Specific embodiment
Heatless regeneration formula dried-air drier mainly is made up of drying tower A and drying tower B; Drying tower A bottom is communicated with muffler by the exhaust Pneumatic butterfly valve of drying tower A, and drying tower A bottom is communicated with admission line by the air inlet Pneumatic butterfly valve of drying tower A, and drying tower A top connects outlet pipe by the check-valves of giving vent to anger of drying tower A; Drying tower B bottom is communicated with muffler by the exhaust Pneumatic butterfly valve of drying tower B, and drying tower B bottom is communicated with admission line by the air inlet Pneumatic butterfly valve of drying tower B, and drying tower B top connects outlet pipe by the check-valves of giving vent to anger of drying tower B; Drying tower A top is connected with drying tower B top by choke valve.
Described heatless regeneration formula dried-air drier, drying tower is by stent support, the drying tower bottom is provided with air inlet, the inner air inlet of drying tower top is provided with baffle plate, between baffle plate and the body of the tower space is arranged, the baffle plate top is provided with the adsorbent bed of horizontal positioned, be connected with body of the tower around the adsorbent bed, the 10 purpose stainless steel cloths that adsorbent bed is placed by steel plate that is covered with through hole and steel plate top constitute, the drying tower top is provided with opening, opening has the gas outlet in the radial direction, and opening has the shutoff sealing, and shutoff connects tremie pipe downwards, the external diameter of tremie pipe is less than the internal diameter of opening, the feed opening lower end connects the air permeable plate that is cone, and air permeable plate is provided with several through holes, is connected with body of the tower around the air permeable plate lower end.
Open shutoff, dry adsorbent is poured in the drying tower, fill up the whole whole space that forms by adsorbent bed, body of the tower, air permeable plate and tremie pipe, then with shutoff good seal opening by tremie pipe.
Dry adsorbent adopts activated alumina and molecular sieve layering to load in mixture.
Utilize transformation absorption, regeneration cycle, make compressed air alternately be full of dry adsorbent drying tower A and drying tower B through two, that is: drying tower is under high partial pressures (1M Pa) state during adsorbed water steam, another tank body is resolved down in low dividing potential drop (0.7M Pa), switches by the time-program(me) of setting then.
