Temperature needed for space division enters back at the top of air cooling tower and carries out direct contact heat transfer with the air risen, thus make air cooling-down, it is multiple
The recirculated water of heat is returned to water-cooling tower from air-cooled tower bottom.
When the gas of above-mentioned air separation unit production is used for the medicine of GMP standard, food production system, recirculated water is air-cooled
Bacterium can be bred for a long time in tower, water-cooling tower and turbidity rises, and be will increase quality risk after contacting with the air, be unable to reach GMP
Production requirement.
Utility model content
The purpose of the utility model is to provide a kind of air precooling systems of air separation unit, avoid in water circulation system
Bacterium or other materials touch raw air, and the gas of production is made to meet the GMP standard of pharmacy, food service industry.
Purpose of the utility model is realized as follows: a kind of air precooling system of air separation unit, the system comprises

The air inlet of contracting machine is connected, and the gas outlet of raw air compressor is connected with raw air efferent duct, raw air efferent duct
The other end accesses raw air purifier, and water recirculator and freezing water cooling are disposed on the raw air efferent duct
But device, raw air efferent duct are entered by the shell of water recirculator and freezing water cooler, and recirculated water and chilled water are by following
The tube side of ring water cooler and freezing water cooler enters.
Above-mentioned recirculated water is conveyed by circulating water pipe, and circulating water pool and water circulating pump, water circulating pump are provided on circulating water pipe
Recirculated water is driven to recycle in circulating water pipe.
Above-mentioned chilled water is conveyed by chilled water pipe, and chilled water pump and water cooler, chilled water pump are provided on chilled water pipe
Chilled water is driven to recycle in chilled water pipe.
The temperature of above-mentioned recirculated water is room temperature.

Check-valves is provided on raw air efferent duct between above-mentioned raw materials air compressor and water recirculator.
Compared to the prior art the utility model, has the following beneficial effects:
The type of cooling of the utility model is: hot raw air successively enters water recirculator and chilled water by shell
Cooler, recirculated water and chilled water enter water recirculator and freezing water cooler by tube side, and recirculated water and chilled water are cold
But it is not directly contacted with heat exchange with raw air in device, the temperature of raw air is made to be down to the required temperature into before purifier.
Due to being not directly contacted with, bacterium or other materials in water would not enter in raw air, so that air separation plant produces
Gas out meets the GMP standard of pharmacy, food service industry.
In addition, first using circulating water, chilled water cooling is reused, so that cooling effect is more preferable, is consumed energy lower.
