Specific embodiment
The present invention is described in further details with reference to the accompanying drawing.
Inventive closure formula water circulation air purification system, including level-one compressor 1, two-stage compressor 2, motor 3, heat exchange
Device 4, condenser 5, separator 6, turbine 7, front filter 8, water tank 9, after-filter 10 and pump 11.
The level-one compressor 1 is connected with turbine 7, drives work by turbine 7.The outlet end of level-one compressor 1 is successively
It is connected by water-flow circuit 13, cooling line 12 with the arrival end of two-stage compressor 2, two-stage compressor 2 is driven by motor.Ring
Border air enters water-flow circuit 13 by the outlet of level-one compressor 1 after the compression of level-one compressor 1.On water-flow circuit 13
Design has spout 13a, and the liquid water sprayed by spout 13a cools down the air in water-flow circuit 13, is formed
Humid air containing vapor, and enter two-stage compressor 2 through cooling line 12 and compress；Two-stage compressor 2 is discharged when working
A part of heat transfer to water-flow circuit 13, so that the liquid water for being not converted into vapor in water-flow circuit 13 is converted into water
Steam avoids it in 2 inside of two-stage compressor for a long time in the state of air-flow with water droplets.The outlet end of two-stage compressor 2 is logical
It crosses pipeline and is connected with heat exchanger 4, condenser 5 and separator 6 in turn；Wherein, the part heat in humid air is absorbed by heat exchanger 4
Amount, is delivered to condenser 5, and most of heat is discharged in condenser 5, reaches hypersaturated state, and with the suspension in air
Grain object condenses vapor sufficiently as the nuclei of condensation, at this point, original particle suspensions can be because of the condensation of vapor in air
Effect is removed, and the pernicious gases such as sulfhydryl compound, oxygen sulfur compound and ammonia in industrial exhaust gas can be dissolved in condensation
In the liquid water of generation.Separator 6 is used to separate the liquid water for condensing generation in condenser 5, obtains suspending containing particle
The liquid water and pure air of the impurity such as object；Then liquid water and pure air are handled respectively by two-way pipeline, had
Body are as follows:
All the way be used to handle the liquid water containing impurity such as particle suspensions, employing mode are as follows: by separator 6 by pipeline according to
After secondary connection front filter 8, water tank 9, after-filter 10, pump 11, heat exchanger 4 is accessed；And heat exchanger 4 is followed by pipeline and water
Spout 13a connection in loop back path 13.Enter as a result, through the liquid water containing impurity such as particle suspensions that separator 6 is discharged
After front filter 8 filters out liquid impurities in water, it is sent into water tank 9, water tank 9 plays heat sink and buffering, protects water temperature in water tank 9
It holds constant.After water in water tank 9 is delivered to the progress secondary filter of after-filter 10, heat exchanger 4 is pumped to by pump 11, by heat exchanger
After 4 absorb heat, water-flow circuit 13 is sprayed by spout 13a, realizes the closed circulation in water route.
Another way is used to handle pure air, employing mode are as follows: separator 6 is passed through piping connection to turbine 7.As a result,
The pure air being discharged through separator 6 expands cooling in turbine 7, and adjusts temperature heel row on the cold side for entering condenser 5
Out.The expansion work of turbine 7 is for driving stage compressor 1.
