Technical field
The utility model relates to a kind of heat of compression of utilizing and carries out thermal regeneration, but the compressed air drier of consumption of compressed air cold blowing not.
Background technology
In the prior art, a kind of compression heat regeneration absorption drier is arranged, it utilizes air compressor machine high-temperature exhaust air heat, adsorbent is regenerated, and it combines heatless regeneration and hot regeneration techniques is arranged, and can produce the dry air of low dew point, and do not need air blast and heater, its operation principle is:
The high temperature malaria, at first directly enter regenerator, the adsorbent that has adsorbed moisture is heated, the high gas of high temperature that is higher than 110 ℃ has enough energy, and moisture is parsed from adsorbent, and the relative humidity of high temperature air is lower, compare with adsorbent humidity, enough difference are arranged, therefore the large quantity of moisture that parses can be taken away
Then, the high temperature malaria, flow through water-cooling type heat exchanger cooling after, reduced temperature, discharge a large amount of liquid moisture, by the filter filtering, enter again drying machine and carry out drying processing, this process is similar to common heatless regeneration drying machine.Air after dry the processing has used through just providing behind the after-filter elimination dust,
Regenerator, after finishing heating process, need to cool off and purge, in order to drop into subsequently dry work, the method that cooling purges is: allow whole high temperature compressed airs through supercooling, after the filtration, all enter drying tower and carry out the drying processing, allow simultaneously the regenerator venting reduce pressure, and draw a small amount of low temperature dry air from the gas outlet of drying machine, regenerator is purged, and sweep gas is discharged drying machine. reduce the temperature of adsorbent, after purge finishes, regenerator boosts, whole regenerative process just is through with, and purging air consumption is 2% of total air inflow, during purging and the ratio of heat time heating time be about 1:1, therefore, the average air consumption of whole circulation is about 1%.
Although existing technology has solved: reduce the dew point of output gas, reduce air consumption, energy consumption cost is low, does not need heater, air blast.But air consumption still exists, and energy consumption will be mended consumption, only has air consumption is reduced to zero, has just really solved the energy loss problem, makes energy consumption cost minimum.
