Operation principle of the present utility model is, is first adsorption process (from top to bottom): the compressed air that water content reaches capacity enters drying machine by import, switches butterfly valve enter the second drier bucket groove from the first entrance; Flow distributor can be guaranteed the uniform distribution of humid air; Simultaneously moist compressed air will pass through drier bucket groove the second drier bucket groove from bottom to top, and the water vapour agent that will be dried is adsorbed.Through dried air, will enter each by dump valve the first dump valve and use point; Secondly: desorption process, at compressed air, when the second drier bucket groove is dry, the first drier bucket groove that moisture reaches capacity starts to carry out regenerative process.Before reproducer starts, the pressure in the first drier bucket groove will slowly decline, until atmospheric pressure.The absorption drier of FRA series is used atmospheric air to carry out desorption processing.Air blast is delivered to atmosphere in heater below, by air heat to desired desorption temperature; Secondly, air enters the first drier bucket groove by the 3rd valve and the 5th valve and carries out desorption processing; The moisture adsorbing then along with air-flow is discharged into atmosphere from valve the 4th entrance switching butterfly valve and the first valve, carries out evaporation by back draught, moisture enters air with prestissimo from equipment; Under the evaporation of moisture, the air being heated will obtain cooling when flowing through drier bucket groove, and temperature during all desorption Bas Dischargeds is far from evaporating temperature so high (being about 40-60 ℃); Along with desorption process carries out, the reduction of moisture, the temperature of desorption air will rise; Once reach after desired temperature, desorption process will stop.
Refrigerating function, for temperature after avoiding changing and dew point reach the highest, the heat storing in drier (after the desorption) air draught that will be cooled is taken away.The direction of cooling blast is the same with adsorption process, from top to bottom.By making to prevent that in this way drier from transshipping, this will affect dry mass greatly.After cooling program completes, regeneration valve will be closed, and drier bucket groove B2 is by slowly supercharging.Once pressure and system pressure are consistent, will enter alternate program.
Standby operation: if controlled and stopped adsorption cycle by dew point measurement device, the standby time is depended on the saturation degree of drier in the second drier bucket groove 42.Once reach the drying capacity (pressure leak source increase) of drier, start program changed; If adsorption cycle was controlled by the time, once reach so after predefined cycle time, start program is changed.
Parallel work-flow: before starting the first drier bucket groove and the conversion of the second drier bucket groove program, two bucket grooves all start parallel work-flow by opening the 3rd entrance switching butterfly valve.After 5 to 15 minutes (can regulate separately), compressed air stream will enter two bucket grooves simultaneously.
Finally, after parallel work-flow finishes, regeneration drier bucket groove will carry out the following step: first entrance of closing the second drier bucket groove reaching capacity switches butterfly valve; Closing presure is recovered valve; Open and will carry out the pressure relief valve of the bucket groove of regenerative operation; Open regeneration valve; Connect present moisture the second drier bucket groove reaching capacity of air blast and heater and enter desorption manipulation, the first drier bucket groove starts dried compressed air simultaneously.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, is therefore intended to include in the utility model dropping on the implication that is equal to important document of claim and all changes in scope.Any Reference numeral in claim should be considered as limiting related claim.
