Working principle of air dryer:
Air drying is the removal of moisture in the air, there are two forms: adsorption and freezing. Adsorption type compressed air dryer using the principle of pressure swing adsorption, wet air through the adsorbent, water is adsorbed, get dry air; The refrigerated compressed air dryer uses the principle of cooling air and reducing the air temperature to precipitation the moisture in the wet air from the air after condensation to get dry air.
Features:
without heat regenerative air dryer is through the "pressure change "(PSA principle) to achieve the drying effect. Due to the ability to hold water vapor gas is inversely proportional to the pressure, the part of the dry air (called again angry) decompression expansion to atmospheric pressure, the pressure change make expanding gas more dry, then let it flow through to regeneration of desiccant layer (i.e., have to absorb enough water vapor drying tower), the water in the dry gas sucked out desiccant, Take it out of the dryer to achieve the purpose of dehumidification. The two towers work in cycle, without heat source, and provide dry gas to the user's gas system continuously. For chemical, light industry, telecommunications, petroleum, textile and other industries of pneumatic control, pneumatic instruments, pneumatic components and industrial gas supply of dry compressed air source, with small size, simple process, investment, easy to use and maintenance, automatic control, energy saving and so on
Process of air dryer:
without heat regenerative air dryer is a kind of unit equipment, but it must be matched with air compressor, cooler, buffer tank and other equipment into the air purification system, the process is as follows:
The compressor compressed air to the cooler, the temperature fell to 40 ℃ or less, again into the buffer tank, degreaser, from the inlet on the dryer cut-off valve IA or IB) into the column A (or B) for temperature in addition to dry, then from the upper part of the check valve CA (CB) output, of which about 85% of the dry air as A finished product after dust filter input air tank, For user use. About 15% of the dry air passes through the re-gas limit valve D on the dryer and enters the drying tower B(or A), which is used as the B tower (or A tower) to regenerate the gas, and the wet air after regeneration is discharged into the atmosphere by the exhaust cut-off valve RB(or RA) through the muffler.
Equipment work for 10 minutes, regeneration cycle regeneration process for 4 minutes, electric control signals, the pressure is mounting on tower B (A), in 4 minutes 5 seconds, tower B (or A tower) ino, make the tower B (or A tower) of pressure to work pressure value, in exchange, the two tower pressure balance; At 5 minutes, the electric control box sends out A signal to close the intake shut-off valve IA(or IB) and open the exhaust shut-off valve RA(or RB), and tower A(or tower B) begins to enter the regeneration stage, so that the repeated circulation continuously sends out dry air, and the dryer itself is also continuously regenerated.
