Description

Drop into the air separation unit of rectifying operation fast
Technical field:
The utility model relates to a kind of equipment that makes gas or admixture of gas liquefy or separate through pressurization and cooling processing, refers in particular to a kind of air separation unit of quick input rectifying operation.
Background technology:
At present; The big-and-middle-sized oxygenerator that uses in the production generally all be with air by compressor compresses, through the cooling after portion of air obtain low temperature through decompressor; 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.
Summary of the invention:
The utility model provides a kind of air separation unit that can improve the quick startup of air separation unit productivity ratio and energy savings.
The utility model is realized through following technical scheme: the air separation unit that drops into the rectifying operation fast comprises that 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, storage tank feed tube link 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, the other end and the above oxygenerator group of cover, and cold liquid oxygen circulation pipe of the master between two units and storage tank interconnected through communicating pipe, also were provided with communicating valve on the pipeline; This device comprises the above oxygenerator group of two covers, and cold liquid oxygen circulation pipe of the master between two units and storage tank interconnected through communicating pipe, also were provided with communicating valve on the pipeline; Storage tank is a cryogenic liquid tank lorry.
The utility model improvements are 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 utilize the vaporization of low temperature liquid oxygen to absorb 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 nominal situation.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
As shown in Figure 1, this device comprises 2 cover oxygenerator groups, and 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 through communicating pipe 19; Communicating valve 4,5,6 on communicating pipe 19 is cold angle valve, and 7 of storage tank 3 and storage tank boosters are communicated with corresponding feed liquor valve 10, the tapping valve 11 of being provided with on it through storage tank booster feed tube 8 and storage tank booster discharging tube 9; 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 with main cold 1, the liquid oxygen pump 16 that outlet is connected with main cold liquid oxygen circulation pipe.
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# oxygenerator group 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# oxygenerator group master reached certain altitude, 1# oxygenerator group was because of receiving 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, be about to the unnecessary liquid of 1# oxygenerator and be transported in the storage tank and accumulate.
When 2# oxygenerator group is normally moved, when 1# oxygenerator group starts, can utilize communicating pipe 19 oppositely to use.Open cold angle valve 6, stop valve 13, cold angle valve 5 and 1# oxygenerator group liquid oxygen adsorber by-passing valve are closed when stop valve 13 frostings, and 2# oxygenerator group liquid gets into 1# oxygenerator master cold 1.Because the resistance of liquid oxygen adsorber 17 when cold angle valve 5 mistake liquid are slow, can be closed cold angle valve 5, opens stop valve 15.When the cold liquid level of 1# oxygenerator group master reach a certain height, after pressure rose gradually, 2# oxygenerator group liquid can not be mended into 1# oxygenerator group by pressure reduction, opened cold angle valve 4, closed cold angle valve 6 and can liquid 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 through 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# oxygenerator group master; Open stop valve 15 or cold angle valve 5, to the cold anti-topping up body of 2# oxygenerator group master.
