The Working Principle of Compressed Air Dryer

Clicks: 2246

A: Refrigerated dryer

The refrigerated dryer uses the cooling air to precipitate the moisture of the moist air from the air after condensation and obtain the drier air.

working principle

The humid and high temperature of the compressed air into the front cooler (high temperature type) heat dissipation into the heat exchange and discharged from the evaporator cool air for heat exchange, so that the compressor into the compressed air temperature.

After the heat transfer of compressed air into the evaporator through the evaporator heat transfer function and refrigerant heat exchange, compressed air heat is taken away by the refrigerant, compressed air quickly cooled, moisture in the humid air to saturation temperature quickly condensed, After the condensation of water after the formation of water droplets, through the gas-water separator high-speed rotation, the role of centrifugal force and air separation, separation of water from the automatic drainage valve discharge. After the cooling of the compressed air pressure dew point theory up to +3 ~ +10 ℃, the general measured at +20 ℃ above.

B: Adsorption dryer

Adsorption dryer using the principle of pressure swing adsorption, wet air through the adsorbent, the moisture absorbed by the adsorbent to get dry air.

working principle

A large amount of air discharged from the air compressor flows through the compressed air inlet pipe and enters the running tower in the two towers through the valve, where the moisture is absorbed by the adsorbent and dried. When the air flow to the top of the tower, the moisture in the air is completely absorbed, the pressure dew point of up to -20 ~ -70 ℃, so as to achieve the purpose of drying, the entire cycle standard takes 10 minutes, each tower for 5 minutes, During the course of work (running tower), the other tower in the regeneration state (non-operating tower) regeneration time of 4.5 minutes, continued pressure time 0.5 minutes. During the regeneration process, a portion of the dry air in the running tower enters the non-operating tower by the regenerated air volume control valve to bring the water in the tower to the atmosphere through the silencer. Its operating time for the amount of equipment handling capacity of 12% to 15%....

Heatless regeneration: regeneration of dry air by the regeneration of the air flow control valve into the regeneration group outlet buffer chamber, dry gas in the regeneration group core adsorption chamber expansion after decompression to atmospheric pressure, from top to bottom on the regeneration of the sub-sieve to purify the adsorbent In vivo molecular sieves and adsorbent separation, analysis in dry air, with the regeneration of gas from the muffler excluded. Regeneration gas consumption ≤ 5%

Heated regeneration: regeneration of dry air through the regeneration of the air flow control valve into the regeneration group outlet gas flow chamber, high temperature dry gas in the regeneration group core adsorption chamber expansion decompression to atmospheric pressure, from top to bottom on the regeneration of the sub-sieve for cleaning, adsorption Agent will speed up the body of water and adsorbent separation, analysis in dry air, with the regeneration of gas from the muffler discharge.
