Description
Technical field
The chilldown system in cryogenic air separation unit is the utility model is related to, more particularly to a kind of chilldown system that improves puts into operation effect
The matched tube structure of rate.
Background technology
Space division unit is the separator of the various composition of air in modern plant, takes Cryogenic air separation technology
Space division unit include air compressor system, chilldown system, molecular sieve system, expander system, fractionating system, output of products system,
Circulation etc., wherein chilldown system are used to reduce air themperature.At present, the process of putting into operation of chilldown system is in air compressor machine liter
After pressure terminates, successively start cooling water pump and start chilled water pump, restart refrigerator and chilled water is cooled down, need to wait for
Chilled water temperature could carry out follow-up power-on operation after being reduced to assigned temperature, and flow is complicated, and system link is more, chilldown system
Put into operation less efficient, space division unit starting energy consumption is larger.
Utility model content
The utility model provides a kind of chilldown system that improves and put into operation the matched tube structure of efficiency in view of the shortcomings of the prior art,
The structure can securely and reliably improve chilldown system and put into operation efficiency, reduce the startup energy consumption of space division unit.
The technical solution of the utility model is：A kind of chilldown system that improves puts into operation the matched tube structure of efficiency, and the structure includes
First valve, the second valve, branch pipe, the branch pipe is arranged between refrigerator and water-cooling tower, for connecting refrigerator and water cooling
Tower；First valve is arranged on the pipeline between air cooling tower and refrigerator, for controlling chilled water in air cooling tower and freezing
Flowing between machine；Second valve is arranged on branch pipe, for controlling stream of the chilled water between water-cooling tower and refrigerator
It is dynamic；The chilled water pump is arranged between refrigerator and water-cooling tower, for conveying chilled water into refrigerator from water-cooling tower.
Further, the branch pipe is that carbon steel or stainless steel is made.
Further, first valve, the second valve use the stop valve or butterfly valve of forced seal formula, both at not
The steel that becomes rusty is made.
Compared with prior art, the utility model has the advantages that：It ensure that chilldown system in the same of air compressor machine boost process
When chilled water continued down in the presence of refrigerator, and reach assigned temperature, after air compressor machine boosting terminates, it is not necessary to again
Start refrigerator or wait cooling water temperature, simplify power-on operation, reduce the startup time of space division unit, improve precooling
The efficiency that puts into operation of system, space division unit is shortened from the time for starting to out oxygen, reduce the startup energy consumption of space division unit.
Brief description of the drawings
Fig. 1 is the utility model schematic flow sheet：
10- air cooling towers, 20- cooling water pumps, 30- chilled water pumps, 40- refrigerators, 50- water-cooling towers, the valves of 11- first, 12-
Second valve, 13- branch pipes.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As shown in figure 1, a kind of chilldown system that improves puts into operation the matched tube structure of efficiency, the structure includes the first valve 11, the
Two valves 12, branch pipe 13, the branch pipe 13 is arranged between refrigerator 40 and water-cooling tower 50, for connecting refrigerator 40 and water cooling
Tower 50；First valve 11 is arranged on the pipeline between air cooling tower 10 and refrigerator 40, for controlling chilled water in air cooling
Flowing between tower 10 and refrigerator 40；Second valve 12 is arranged on branch pipe 13, for controlling chilled water in refrigerator
Flowing between 40 and water-cooling tower 50.
Chilldown system opens the second valve 12 while air compressor machine boost process, closes the first valve 11, makes chilled water
Flowed between refrigerator 40, water-cooling tower 50, chilled water pump 30, i.e., chilled water is also being carried out while air compressor machine boost process
Temperature-fall period；At the end of air compressor machine boosts, the second valve 12 is closed, opens the first valve 11, makes chilldown system input normal
Use, now chilled water have been lowered to assigned temperature, chilled water can be directly entered air cooling tower in the presence of chilled water pump 30
10, subsequent operation can be carried out without waiting for the temperature-fall period of chilled water, meanwhile, pressurizeed by cooling water pump 20 to air cooling tower 10
Conveying cooling water cools down to air, shortens space division unit from the time for starting to out oxygen.
The above should be understood to that these embodiments are only used for being illustrated more clearly that the utility model, rather than limitation
The scope of the utility model, after the utility model has been read, those skilled in the art are to various equivalences of the present utility model
The modification of form each falls within the application appended claims limited range.
