The working principle and the course of work of heatless regeneration absorption drier 100 are as follows:
When desiccant being arranged in the first drying tower 120 for dry and the second drying tower 130 is used for water desorption, that is, drying
When agent regenerates, gas flows through the first air inlet from air inlet pipe 110 and is in charge of 111 into the first drying tower 120, and gas is contacted with desiccant
Moisture removal is gone to be able to drying.At this point, the first entrance 172 of shuttle valve 170 is connected to outlet 176, second entrance 174 is closed.By
Gas after first drying tower 120 is dry, a part flow through the first entrance 172 of shuttle valve 170, flow into dry gas from outlet 176
It is flowed out after body escape pipe 140；Another part flows into the second drying tower 130 through electric control valve 150, becomes regeneration air stream.Regeneration
After air-flow enters the second drying tower 130, desiccant and water desorption, desiccant regeneration.Regeneration air stream containing moisture passes through the
Two escape pipes 183, are emitted into atmosphere after flowing through silencer 186.
When desiccant being arranged in the second drying tower 130 for dry and the first drying tower 120 is used for water desorption, that is, drying
When agent regenerates, gas flows through the second air inlet from air inlet pipe 110 and is in charge of 113 into the second drying tower 130, and gas is contacted with desiccant
Moisture removal is gone to be able to drying.At this point, the second entrance 174 of shuttle valve 170 is connected to outlet 176, first entrance 172 is closed.By
Gas after second drying tower 130 is dry, a part flow through the second entrance 174 of shuttle valve 170, flow into dry gas from outlet 176
It is flowed out after body escape pipe 140；Another part flows into the first drying tower 120 through electric control valve 150, becomes regeneration air stream, enters
After first drying tower 120, desiccant and water desorption, desiccant regeneration.Regeneration air stream containing moisture passes through the first escape pipe
181, atmosphere is emitted into after flowing through silencer 186.
First drying tower 120 and the second drying tower 130 can alternately dry and desiccant regeneration as a result,.
