Abstract
The utility model relates to an external liquid oxygen subcooler which comprises a machine case and an interior circulating system, and comprises a gas sealing cylinder (2), a liquid oxygen inlet (11), a liquid oxygen outlet (12), a liquid nitrogen inlet (13) and a liquid nitrogen outlet (14). When the external liquid oxygen subcooler is used, liquid nitrogen is changed into low-temperature nitrogen to return to a low-temperature nitrogen passage of a main heat exchanger in a cooling box; the average evaporation rate of original liquid oxygen is 8 percent, and the present average evaporation rate is 3 percent; the cost is greatly saved.
Description
Technical field
The utility model relates to a kind of refrigeration plant, relates in particular to a kind of liquid oxygen supercooler.
Background technology
Generally in empty branch trade, (temperature is lower than evaporation point in order to improve fluid product degree of supercoolings such as liquid oxygen, liquid nitrogen, in order to reduce the vaporization rate of fluid product), all heat exchange on subcooler of liquid in ice chest, obtain certain degree of supercooling, different with the subcooler of routine, this subcooler is mounted in the ice chest outside.
When entering 350 cubes of normal pressure storage tanks behind the liquid oxygen cooling box, because degree of supercooling is not enough, it is many that liquid oxygen is steamed into gas oxygen, the discharging of gas oxygen is ceaselessly arranged on the liquid oxygen vessel blow-down pipe, and can evaporation capacity be bigger, recycle, the characteristics that are difficult for recovery at low temperature, low oxygen, we change thinking, and proposing increases the liquid oxygen degree of supercooling with liquid nitrogen, so just can reduce the evaporation capacity of liquid oxygen.According to simple computation, cross cold 6 ℃ for the 1400NM3/h liquid oxygen, need liquid nitrogen 77NM3/h to be vaporized into low temperature nitrogen emptying.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of external liquid oxygen supercooler, to solve the big defective of liquid oxygen evaporation capacity in the prior art.
Technical scheme
The utility model provides a kind of external liquid oxygen supercooler, comprises casing and inner loop system, comprises envelope inflator 2, liquid oxygen import, liquid oxygen outlet, liquid nitrogen import and liquid nitrogen outlet.
Beneficial effect
Liquid nitrogen is through becoming the low-pressure nitrogen passage that low temperature nitrogen returns main heat exchanger in the ice chest behind the subcooler; Originally the average evaporation rate of liquid oxygen is 8%, and average out to 3% has been saved cost greatly now.
