Liquid oxygen pump water bath type vaporization device

Abstract

The invention relates to a liquid oxygen pump water bath type vaporization device, and belongs to the technical field of oxygen preparation, the liquid oxygen pump water bath type vaporization device comprises a water bath type vaporizer, and one side of the water bath type vaporizer is sequentially provided with a circulating water pipe inlet, an overflow water pipe outlet, a liquid oxygen pipe inlet and a circulating water pipe outlet from top to bottom; an oxygen pipe outlet and a water vapor inlet are formed in the top end of the water bath type vaporizer, the top end of the water bath type vaporizer is further communicated with a water-sealed tank through a water vapor outlet pipe, an external pipe for water inlet and outlet is arranged at the upper end of the water-sealed tank, an L-shaped pipeline is arranged at the lower end of the water-sealed tank, and a valve is arranged on a transverse pipe of the L-shaped pipeline. And a water vapor absorption accelerant is filled in a transverse pipe on one side, far away from the water bath vaporizer, of the valve and a vertical pipe of the L-shaped pipeline. The device is simple and low in cost, water in the water-sealed tank is used for absorbing water vapor left after heat exchange, a proper amount of potassium nitrate is added into the water to promote absorption when the amount of the residual water vapor is large and the residual water vapor cannot be completely absorbed, and potential safety hazards caused by release of the residual water vapor are avoided.

Description

technical field [0001] The invention relates to a liquid oxygen pump water bath type vaporization device, which belongs to the technical field of oxygen preparation. Background technique [0002] At present, there is a large oxygen gap in the oxygen production supply system, which needs to be supplemented by vaporizing a large amount of liquid oxygen. The low-temperature liquid oxygen is pressurized by a liquid pump and then enters the water bath vaporizer. The water bath vaporizer circulates water and steam to replace the low temperature liquid oxygen. Low-temperature liquid oxygen flows inside the tube, steam flows outside the tube, and part of the condensed water flows back after the heat exchange, and the residual steam of the heat exchange is released through the top pipe, but the release of the residual steam will easily cause the humidity in the local area to increase, which is harmful to electrical equipment. , Corrosion pollution of storage tank equipment; In additi...

[0002] At present, there is a large oxygen gap in the oxygen production supply system, which needs to be supplemented by vaporizing a large amount of liquid oxygen.

The water bath vaporizer circulates water and steam to replace the low temperature liquid oxygen. Low-temperature liquid oxygen flows inside the tube, steam flows outside the tube, and part of the condensed water flows back through the heat exchange, and the residual steam of the heat exchange is released through the top pipe, but the release of residual steam will easily cause the humidity in the local area to increase, which is harmful to electrical equipment. , storage tank equipment corrosion pollution; in addition, the steam mist structure causes poor visibility in the area, and the condensation of overflow steam results in a poor ground operating environment, which brings potential safety hazards
