Description
The utility model relates to a kind of equipment that makes gas or admixture of gas liquefy or separate by pressurization and cooling processing, particularly fast and stable and drops into the air separation unit of rectifying operation.
At present, the big-and-middle-sized oxygenerator that uses in the production generally all is by compressor compresses, portion of air is obtained low temperature through decompressor after cooling off with air, another part air advances to cool off rectifying column and plate type heat exchanger cooling and liquefaction back to be separated in rectifying column, produces oxygen and nitrogen etc. respectively.Because supporting with it expander refrigeration ability is little, the start-up time of its air separation unit, board-like flow process reached about 40 hours mostly, and the molecular sieve flow startup time was at 70-80 hour, and is that have even longer.Air separation unit product-free output in start-up course, and supporting with it corollary equipments such as air compressor machine consumed power as usual.So start-up time is long more, then water, electric flux consumption are high more.
The utility model purpose is to overcome above-mentioned shortcoming of the prior art and air separation unit that a kind of quick startup is provided, thereby realizes improving the purpose of air separation unit productivity ratio and energy savings.
The purpose of this utility model is achieved by the following technical solution:
During forming, the air separation unit of fast and stable input rectifying operation comprises main cold, main cold liquid oxygen circulation pipe, storage tank, storage tank booster, storage tank feed tube, storage tank booster feed tube, storage tank booster discharging tube, the storage tank feed tube links to each other with main cold liquid oxygen circulation pipe, main cold liquid oxygen circulation pipe links to each other with main cold-peace storage tank, which is provided with communicating valve.One end of the feed tube of storage tank booster, liquid back pipe connects the storage tank booster, and the other end links to each other with storage tank.
Can comprise the above oxygenerator group of 2 covers during the utility model is formed, the communicating pipe between two units is interconnected with main cold liquid oxygen circulation pipe and storage tank, and pipeline is provided with communicating valve.Above-mentioned storage tank also can be a cryogenic liquid tank lorry.
Key improvements part of the present utility model is will lead between cold and storage tank and cold of the master of two above oxygenerator groups is communicated with the liquid oxygen circulation pipe.When needing, open the valve on the pipeline, the liquid oxygen that operation oxygenerator group master is stored in the cold or storage tank is counter deliver to the master who starts unit cold in, thereby the vaporization that utilizes the low temperature liquid oxygen absorbs a large amount of evaporation latent heats, auxiliary expander refrigeration, thereby make the cold accumulating liquid as early as possible of master that starts unit, set up normal rectifying operating mode.
The utility model can fast, stably drop into the rectifying operation, can shorten start-up time more than 60%, reduces water, electric energy consumption when starting significantly, boosts productivity, and reduces the empty cost that divides.
Accompanying drawing is the structural representation of the utility model embodiment.
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
Comprise 2 cover oxygenerator groups during the utility model is formed, 1# is board-like flow process oxygenerator group, and 2# is a molecular sieve flow process oxygenerator group.The master of oxygenerator group cold 1 links to each other with main cold liquid oxygen circulation pipe 2, the cold liquid oxygen circulation pipe 2 of master and the storage tank feed tube 12 of two cover oxygenerator groups interconnected by communicating pipe 19, communicating valve 4,5,6 on communicating pipe 19 is cold angle valve, 7 of storage tank 3 and storage tank boosters are communicated with by storage tank booster feed tube 8 and storage tank booster discharging tube 9, corresponding feed liquor valve 10, the tapping valve 11 of being provided with on it, main cold liquid oxygen circulation pipe is provided with liquid oxygen adsorber 17, is used for adsorbing the impurity of liquid oxygen.1# oxygenerator group also is provided with import and is connected, exports the liquid oxygen pump 16 that is connected with main cold liquid oxygen circulation pipe with main cold 1.
When 1# oxygenerator group is normally moved, when 2# oxygenerator group starts, can pass through communicating pipe 19 to the anti-topping up body of 2# unit by 1# oxygenerator group, utilize vaporizing liquid to obtain cold, cooling device makes main cold accumulating liquid as early as possible.Open cold angle valve 5, stop valve 13,14, crack cold angle valve 6 preheating pipelines.After stop valve 14 frostings, close, open stop valve 15, close cold angle valve 5, to the cold liquor charging of master that starts unit.When the cold liquid level of 2# unit master reached certain altitude, the 1# unit was because of being subjected to the restriction of liquid oxygen pump 16 lifts, and liquid oxygen is crossed and do not come.Open cold angle valve 4 this moment, close stop valve 15, soon the unnecessary liquid of 1# unit is transported in the storage tank and accumulates.
When the 2# unit normally moves, during the 1# unit starting, can utilize communicating pipe 19 oppositely to use.Open cold angle valve 6, stop valve 13, cold angle valve 5 and 1# machine liquid oxygen adsorber by-passing valve are closed when stop valve 13 frostings, and 2# unit liquid enters 1# unit master cold 1.Because the resistance of liquid oxygen adsorber 17 when cold angle valve 5 mistake liquid are slow, can close cold angle valve 5, open stop valve 15.When the cold liquid level of 1# unit master reach a certain height, after pressure rose gradually, 2# unit liquid can not pressured difference mend the 1# unit, opened cold angle valve 4, closed cold angle valve 6 and liquid can be accumulated in the storage tank.
When the cold liquid of unit master adds to certain altitude, when another set of unit liquid can not be annotated into, the liquid in the available storage tank 3 instead was charged to main coldly 1 by communicating pipe 19, continues fluid injection.Close storage tank feed liquor valve 18, open storage tank booster 7 the storage tank internal pressure is increased, open storage tank feed liquor valve 18 again, open cold angle valve 4,6, to the cold anti-topping up body of 1# master; Open stop valve 15 or cold angle valve 5, to the cold anti-topping up body of 2# master.
