Summary of the invention
The purpose of this utility model provides a kind of fluid column supercharging flow process liquid oxygen evaporimeter that is applicable to liquid oxygen evaporation usefulness.
The utility model is by the following technical solutions:
A kind of fluid column supercharging flow process liquid oxygen evaporimeter, comprise shell, be provided with plate-fin heat exchanger in the shell, plate-fin heat exchanger comprises at least one plate fin heat-exchanging unit, and the plate fin heat-exchanging unit comprises oxygen channel and the air duct that is crisscross arranged, wherein, oxygen channel is a straight channel, air duct is a wing passage, and the sidewall of shell is provided with the liquid oxygen inlet pipe, and cover top portion is provided with oxygen and goes out pipe.
Described oxygen channel and air duct are formed by between adjacent two dividing plates fin, flow deflector and strip of paper used for sealing being set respectively, and the import department of described air duct and exit are respectively equipped with end socket and adapter, take over to extend to outside the shell.
The bottom of described shell is provided with base.
The used fin of described air duct is a serrated fin, and flow deflector is straight perforated fin.
The used fin of described oxygen channel is straight perforated fin, and flow deflector is straight perforated fin.
The utility model is applicable to the evaporation of air separation process fluid column supercharging flow process liquid oxygen, liquid oxygen is entered in the shell by the liquid oxygen inlet pipe, the liquid level of liquid oxygen rises gradually and is immersed in the oxygen channel of plate-fin heat exchanger, and air enters air duct by the air inlet pipe simultaneously, air in the air duct and the liquid oxygen heat exchange in the oxygen channel, the heat of vaporization boiling of liquid oxygen absorption air is vaporizated into oxygen and upwards goes out the pipe discharge by oxygen, thus the evaporation of realization liquid oxygen.The utility model is simple in structure, and is easy to use, can be widely used in empty branch field.
The utility model is used for space division system, adopt air to go out fluid column supercharging flow process liquid oxygen evaporimeter with 30% water capacity with dew-point temperature feed liquor post supercharging flow process liquid oxygen evaporimeter, can effectively enlarge the heat transfer temperature difference of fluid column supercharging flow process liquid oxygen evaporimeter, at air compressor machine pressure at expulsion 0.52Mpa(G) under, oxygen goes out fractionating column ice chest pressure and reaches 108Kpa, make the reduction of oxygen compressor pressure ratio directly cause the decline of shaft power, press the oxygen power consumption to decline to a great extent, energy efficient, save resource, and pave the way for the application of reciprocating type oxygen compressor, make oxygen compressor obtain effective dilatation and pressure at expulsion is effectively improved.
