(Summary description)Must the dryer be installed in the air compressor post-treatment equipment? The answer is yes, if your enterprise is useful to the air compressor, you must know that the air compressor must be installed after the dryer. After the air compressor, the air storage tank, filter and dryer and other purification equipment need to be installed. It is well known that when the air around us is compressed, the amount of water molecules per unit volume rises dramatically. The compression process results in air containing not only liquid water, oil, and particulate matter, but also large amounts of saturated water molecules. Once the external temperature drops, the saturated water molecules are affected by the low temperature and precipitate liquid water. The lower the temperature, the more liquid water precipitates. When the temperature drops to zero, the liquid water condenses into ice, resulting in ice blockage. And the compressed air containing too much water molecules will also affect the normal operation of the equipment, corrosion of machinery and equipment, causing damage to pneumatic components and so on. Some people may ask, to remove the water molecules in compressed air, you can directly use a filter to remove it, why buy a large price dryer? Why is that? This is because the filter can only remove liquid water in the compressed air, but the water molecules in the compressed air will continue to precipitate liquid water with the lower the temperature. In addition to liquid water, the water molecules in the compressed air will also affect the life of machinery and equipment and the production process of enterprises. Purchase dryer, can dry the water molecules in the compressed air, so that the compressed air can meet the gas standards of the enterprise, so as to meet the production needs of the enterprise. Investment in air compressor post-treatment equipment dryer return is very high, it effectively reduces the water molecules in the air, avoids the damage of machinery and equipment and gas equipment, can improve the production process of enterprises, reduce the product defect rate, and ensure the quality of products.

Working principle of nitrogen making machine

PSA pressure swing adsorption nitrogen production mechanism nitrogen principle Carbon molecular sieve can absorb oxygen and nitrogen in the air at the same time, and its adsorption capacity also increases with the increase of pressure, and at the same pressure oxygen and nitrogen equilibrium adsorption capacity has no obvious difference. Therefore, it is difficult to complete the effective separation of oxygen and nitrogen only by the change of pressure. If further consideration is given to adsorption rates, the adsorption properties of oxygen and nitrogen can be effectively distinguished. The diameter of oxygen molecules is smaller than that of nitrogen molecules, so the diffusion rate is hundreds of times faster than that of nitrogen, so the speed of carbon molecular sieve adsorption of oxygen is also very fast, adsorption of about 1 minutes to reach more than 90%; At this time, the amount of nitrogen adsorption is only about 5%, so the adsorption is mostly oxygen, and the rest is mostly nitrogen. In this way, if the adsorption time is controlled within 1 minute, you can initially separate oxygen and nitrogen, that is to say, adsorption and desorption are achieved by pressure difference, when the pressure increases adsorption, desorption when the pressure drops. The distinction between oxygen and nitrogen is based on the adsorption speed difference between the two, through the control of adsorption time to achieve, the time control is very short, oxygen has been fully adsorbed, and nitrogen has not yet had time to adsorption, stopped the adsorption process. Therefore, pressure change and time control for nitrogen production by pressure swing adsorption should be within 1 minute.

Air compressor terminology and related knowledge

(1), pressure: the pressure referred to in the compressor industry refers to pressure (P) Ⅰ, standard atmospheric pressure (ATM) Ⅱ, working pressure, suction, exhaust pressure, refers to the air compressor suction, exhaust pressure ① The pressure measured with atmospheric pressure as the zero point is called surface pressure P(G). ② The pressure with absolute vacuum as the zero point is called the absolute pressure P(A). The exhaust pressure usually given on the compressor nameplate is the gauge pressure. Ⅲ, differential pressure, pressure difference Ⅳ, loss of pressure: pressure loss Ⅴ, air compressor, the commonly used pressure unit conversion: 1MPa (MPa) =106Pa (PASCAL) 1bar (bar) =0.1MPa 1atm (standard atmospheric pressure) =1.013bar=0.1013MPa Usually in the air compressor industry, "kg" refers to "bar". (2), nominal flow: nominal flow in China is also known as the displacement or nameplate flow. Generally speaking, under the required exhaust pressure, the gas volume discharged by the air compressor per unit time is converted to the intake state, which is the volume value of the suction pressure and suction temperature and humidity at the first stage of the intake pipe. Unit time refers to one minute. That is, the suction volume Q= CM *λ*D3*N=L/D*D3N L: Length of rotor D: Diameter of the rotor N: The shaft speed of the rotor CM: Coefficient of profile line Lambda: length to diameter ratio According to the national standard, the actual exhaust volume of air compressor is ± 5% of the nominal flow. Reference state: a standard atmospheric pressure, temperature 20℃, humidity is 0℃, this reference state in the United States, Britain, Australia and other English-speaking countries T =15℃. Europe and Japan T =0℃. Standard condition: one standard atmosphere, temperature 0℃, humidity 0 If converted to base state, the unit is :m3/min (cubic per minute) If converted to standard state, the unit is :Nm3/min (standard square per minute) After 1 m/min = 1000 l/min 1 nm after/min after = 1.07 m/min (3) Oil content of gas: Ⅰ, per unit volume of compressed air in the oil (including oil, suspended particles and oil steam), the quality of the conversion to off the pressure of 0.1 MPa, temperature is 20 ℃ and relative humidity of 65% the value of the standard atmospheric conditions. Unit :mg/m3 (refers to absolute pair value) Ⅱ, PPM said a trace substances content in the mixture of symbols, refers to the number in every one million hundreds million (weight than PPMw and volume than PPMv). (referring to the ratio) Usually we refer to PPM as the weight ratio. (One millionth of a kilogram is a milligram) 1PPMW =1.2mg/m3(Pa =0.1MPa, t=20℃, φ=65%) (4) Specific power: refers to the power consumed by a certain volume flow of the compressor. It is a kind of index to evaluate the compressor performance under the same gas compression and the same exhaust pressure. Specific power = shaft power (total input power)/ exhaust (kW/m3·min-1) Shaft power: The power required to drive the shaft of the compressor. P axis =√3×U×I× COS φ(9.5)×η(98%) motor ×η drive (5), electrical and other terms Ⅰ, power: current per unit time to do the work (P), the unit is W (watt We usually use kW (kilowatt), but also horsepower (HP) 1 KW HP1HP = 1.34102 = 0.7357 KW Ⅱ, current: electronic under the action of electric field force, there are rules of move in one direction When it moves, it forms A current in A amperes. Ⅲ, voltage: just because have head and water flow, there is also a potential difference, It is called voltage (U), and the unit is V (volts). Ⅳ, phase, refers to the wire, three phase four wire: refers to the three phase thread (or wire) The center line (or zero line), single phase refers to a phase line (or fire line) Root center line (or zero line) Ⅴ, frequency: alternating current (ac) to complete the electromotive force of the positive and negative transformation cycles a second number, use (f), according to the unit - Hertz (Hz) of 50 Hz alternating current frequency in our country, abroad is 60 Hz. Ⅵ, frequency: change the frequency, in air compressor application, by changing the frequency of the power to change the speed of the motor, so as to achieve the purpose of flow adjustment. The flow rate can be adjusted to 0.1bar by frequency conversion, which greatly reduces idle work and achieves the purpose of energy saving. Ⅶ, controller: there are two main types of controller in industry: instrument type and PL System, we use PLC controller, is a kind of by A programmable controller composed of single chip microcomputer and other components.

Air compressor room size design matters needing attention

A lot of air compressor users ignore the importance of the design of air compressor room. They think that the air compressor is installed there as long as it is not in the way. But in the late stage, they have learned the bitter fruit of unreasonable design of air compressor room. In summer, air compressor room heat dissipation is not good, and high temperature of air compressor frequently occurs; Air compressor maintenance is not convenient; The construction of waste heat recovery engineer of air compressor is not convenient, so we should ensure that the design of air compressor in the air compressor room is reasonable. If you are an engineer, what will you remind your users to pay attention to in the design of air compressor room? 1. Before the design of air compressor room, it is necessary to understand the design specification and matters needing attention of air compressor room. 2. Choose a place with low relative humidity, less dust, clean air and good ventilation. If the ambient temperature is too high (greater than 45℃), it is recommended to take cooling measures (such as avoiding direct sunlight, opening doors and Windows, etc.) to avoid unnecessary high-temperature shutdown; If the ambient temperature is low (less than 0℃), the freezing point temperature of the lubricating oil must be controlled above the ambient temperature. Consider not only summer low temperatures, but also winter low temperatures, and think long term. 3. If the factory environment is poor and dusty, a ventilation duct should be installed to lead the intake end to a place where the air is relatively clean. The installation of the conduit must be easy to disassemble and assemble for maintenance. The installation size should refer to the external size of the air compressor. 4. There must be enough space around the air compressor for other parts to enter and leave. There must be at least a distance of more than 1500mm between the air compressor and the wall. As far as possible with lifting equipment. The distance between the air compressor and the top space is more than 1500mm. In a word, the design of air compressor room should come from the gas demand that you want to meet, and can not be strictly in accordance with the book knowledge. But the basic matters needing attention should be understood and applied to the actual design of the air compressor room.

The operation of argon production in air separation unit is complicated.

Total rectification of argon is to separate oxygen from argon in a crude argon column to obtain crude argon with oxygen content less than 1×10-6 directly, and then separate it from fine argon to obtain fine argon with purity of 99.999%.   With the rapid development of air separation technology and the demand of market, more and more air separation units adopt the process of producing argon without hydrogen to produce high purity argon products. However, due to the complexity of argon production operation, many air separation units with argon did not lift argon, and some units in operation of argon system were not satisfactory due to the fluctuation of oxygen use condition and the limitation of operation level. Through the following simple steps, the operator can have a basic understanding of producing argon without hydrogen!   Commissioning of argon making system   * V766 in full opening process before discharging coarse argon column into fine argon column; Liquid blowout and discharge valves V753 and 754 at the bottom of crude argon tower I (24 ~ 36 hours). * Full opening process argon out coarse argon tower I defining argon tower valve V6; Non-condensing gas discharge valve V760 at the top of the argon tower; Precision argon tower, liquid blowing at the bottom of precision argon measuring cylinder, discharge valves V756 and V755 (precooling precision argon tower can be carried out at the same time as precooling coarse argon tower).   Check the argon pump   * Electronic control system -- wiring, control and display are correct; * Sealing gas -- whether the pressure, flow, pipeline is correct and does not leak; * Motor rotation direction -- point motor, confirm the correct rotation direction; * Piping before and after the pump -- check to make sure the piping system is smooth.   Check the argon system instrument thoroughly   (1) Rough argon tower I, Rough argon tower II resistance (+) (-) pressure tube, transmitter and display instrument is correct; (2) Whether all liquid level gauge (+) (-) pressure tube, transmitter and display instrument in argon system are correct; (3) Whether the pressure tube, transmitter and display instrument are correct at all pressure points; (4) Whether the argon flow rate FI-701 (the orifice plate is in the cold box) (+) (-) pressure tube, transmitter and display instrument are correct; ⑤ Check whether all automatic valves and their adjustment and interlocking are correct.   Main tower working condition adjustment   * Increase oxygen production under the premise of ensuring oxygen purity; * Control the lower column oxygen-rich liquid empty 36 ~ 38% (liquid nitrogen restricts into the upper column valve V2); * Reduce the expansion amount under the premise of ensuring the main cold liquid level.   Liquid in coarse argon column   * On the premise of further precooling until the temperature of the argon tower no longer drops (the blowout and discharge valves have been closed), the liquid air is slightly opened (intermittently) and flows into the condensing evaporator valve V3 of the crude argon tower I to make the condenser of the crude argon tower intermittently work to produce backflow liquid, cool the packing of the crude argon tower I thoroughly and accumulate in the bottom part of the tower; Tip: When opening the V3 valve for the first time, pay close attention to the pressure change of PI-701 and do not fluctuate violently (≤ 60kPa); Obact the liquid level LIC-701 at the bottom of crude argon tower I from scratch. Once it rises to 1500mm ~ full scale range, stop precooling and close V3 valve.   Precooling argon pump   * Stop valve before opening the pump; * Blow out the valve V741 and V742 before opening the pump; * slightly open (intermittently) the pump after blowing off valve V737, V738 until the liquid is continuously ejected. Tip: This work is carried out under the guidance of argon pump supplier for the first time. Safety issues to prevent frostbite.   Start the argon pump   * Fully open the return valve after the pump, fully close the stop valve after the pump; * Start argon pump and fully open the back stop valve of argon pump; * Observe that the pump pressure should be stabilized at 0.5 ~ 0.7Mpa(G).   Crude argon column   (1) After starting the argon pump and before opening the V3 valve, the liquid level of LIX-701 will decrease continuously due to the liquid loss. After starting the argon pump, the V3 valve should be opened as soon as possible to make the condenser of the argon tower work and produce backflow liquid. (2) V3 valve opening must be very slow, otherwise the main tower conditions will produce large fluctuations, affecting the purity of oxygen, crude argon tower after work to open the argon pump delivery valve (opening depends on the pump pressure), the final delivery valve and return valve to stabilize the FIC-701 liquid level; (3) The resistance of two crude argon columns is observed. The resistance of
