Detailed description of the invention
Fig. 1 is the structure chart of prior art adsorption tower, and absorption tower body (103) two ends have for passing in and out compressed-air actuated air vents 15(101,102), absorption tower body (103) inside is full of adsorbent (104).In order to prevent adsorbent (104) from running out of, screen pack (105,106) is housed in absorption tower body (103) inside.The working method of drying tower is divided into adsorption process and regenerative process.Adsorption process: compressed air is from air vents 15(101) enter, by adsorbent (104) by the water adsorption in compressed air in adsorbent (104), dry compressed air is from air vents 15(102) output.Regenerative process: regeneration air is from air vents 15(102) enter, departed from by moisture wherein by adsorbent (104), the air of band water is from air vents 15(101) be disposed to air.During the moisture of adsorbent in adsorption compression air, can discharge a large amount of heats (heat of condensation), adsorbent, when regenerating dehydration, absorb a large amount of heats (heat of vaporization).Particularly when adsorption tower dehydration regeneration, regeneration air is from air vents 15(102) enter to air vents 15(101) discharge, while regeneration air receives moisture, by carrying out when supplementary adsorbent dewaters heat of vaporization with the heat exchange of adsorbent (104), temperature promptly reduces.The temperature of regeneration tail gas directly determines the ability that regeneration air receives steam, and regeneration tail gas temperature is high, and the steam vapour amount that can receive is just many, and regeneration air amount just can correspondingly reduce.The adsorption tower of prior art is owing to only relying on regeneration air to carry heat, and by regeneration air quantitative limitation, promptly the temperature of regeneration tail gas can not be improved (temperature that can reduce regeneration tail gas during heatless regeneration), the water vapour that receives of regeneration air is few in a long time, cause regeneration air consumption to increase, energy consumption increases.In absorption tower adsorbs process, compressed air is from air vents 15(101) enter to air vents 15(102) output, when moisture in compressed air is adsorbed, releases heat (heat of condensation), these heat parts are taken away by compressed air, remaining heat accumulation is inner at adsorption tower, makes the temperature of adsorbent (104) increase.After adsorbent (104) heats up, adsorption efficiency declines, and can only terminate adsorption process in advance and regenerate, reduce the adsorption efficiency of adsorbent (104).
