[0003] When the air-temperature vaporizer performs heat exchange and gasification of liquid oxygen, frosting often occurs on the fins. The occurrence of this phenomenon will greatly reduce the gasification efficiency, and the frosting will further increase in the continuous gasification. Spreading, and then causing the fins to freeze, and even the pipeline to freeze, so a new gasifier is urgently needed to solve the current problems

Embodiment 1
[0025] like Figure 1-3 As shown, a liquid oxygen vaporizer includes a heat exchange tube 3, the heat exchange tube 3 is a W-shaped tube, and the heat exchange tube 3 is provided with a number of heat exchange components 2 at the vertical pipes, and the heat exchange components 2 are up and down. Arranged to the vertical pipe of the heat exchange pipe 3, the heat exchange assembly 2 includes an outer pipe 21, an inner pipe 22, fins 23 and paddles 24; the inner pipe 22 is sleeved at the vertical pipe of the heat exchange pipe 3, and the inner pipe The outer side of 22 is provided with an outer tube 21, between the outer tube 21 and the inner tube 22, four fins 23 are arranged in an annular distribution shape, and the two ends of the fins 23 are respectively connected to the outer tube 21 and the inner tube 22; Six paddles 24 are equally connected to the annular outer surface of the assembly 2 .
[0026] In this embodiment, by arranging the outer tube 21 and the inner tube 22, ...
Embodiment 2
[0029] like Figure 1-4 As shown, a vaporizer for liquid oxygen, the outer pipe 21 includes a pipe body 211, a ball groove 212 and a ball body 213, the annular bottom end of the pipe body 211 is equally provided with four ball grooves 212, and the ball groove 212 has a rolling sleeve A sphere 213 is inserted, and the sphere 213 rolls in contact with the tube body 211 provided on the bottom side.
[0030] In this embodiment, the outer tubes 21 are spaced by the spheres 213 . On the one hand, this arrangement facilitates the relative rotation between the heat exchange components 2 , and on the other hand, avoids the heat caused by the tight fit between the heat exchange components 2 . It is difficult to reach the fins 23, which leads to the problem of poor heat exchange efficiency.
Embodiment 3
[0032] like Figure 1-5 As shown, a liquid oxygen vaporizer, the outer pipe 21 includes a rolling groove 214, the annular top of the pipe body 211 is equally provided with four rolling grooves 214, and the rolling grooves 214 are arranged in a V shape; the groove depth of the rolling groove 214 smaller than the radius of the sphere 213 .
[0033] In this embodiment, a rolling groove 214 is provided at the top of the outer tube 21, so that the heat exchange assembly 2 alternately rolls between the rolling groove 214 and the tube body 211 through the balls 213 during relative rotation, so as to realize the mutual interaction of the heat exchange assembly 2 during rolling. Impact, the impact will generate vibration, so as to achieve the purpose of shocking the frost body.

Abstract
The invention provides a vaporizer for liquid oxygen, which relates to the field of liquid oxygen gasification, and includes a heat exchange tube. In the present invention, the heat exchange tube is a W-shaped tube, and the heat exchange tube is provided with a number of heat exchange components at the vertical pipe. The heat exchange assembly is arranged up and down to the vertical pipe of the heat exchange pipe, and the heat exchange assembly includes an outer pipe, an inner pipe, fins and paddles; the inner pipe is sleeved at the vertical pipe of the heat exchange pipe, and the outer side of the inner pipe is provided with a The outer tube, the outer tube and the inner tube are provided with four fins in an annular distribution shape, and the two ends of the fins are respectively connected to the outer tube and the inner tube; the annular outer surface of the heat exchange component is equally connected with six fins The heat exchange components are arranged in a combined arrangement relative to the heat exchange tubes. This arrangement can rotate the heat exchange components when the heat exchange components are frosted, so that the heat exchange components can quickly absorb the heat in the air to achieve rapid Defrost function.
Description
technical field [0001] The invention relates to the field of liquid oxygen gasification, in particular to a liquid oxygen gasifier. Background technique [0002] Liquid oxygen gasification supply refers to the use of oxygen that meets the national standard as the gas source, and when the ambient temperature is -40 ~ 50 ° C, it is purified, dehydrated and compressed to no more than 25Mpa by the pressurization station, and then filled into the storage device. means of supplying. [0003] When the air-temperature vaporizer conducts heat exchange and vaporization of liquid oxygen, the phenomenon of frosting on the fins often occurs. The appearance of this phenomenon will greatly reduce the gasification efficiency, and the frosting phenomenon will be further in the continuous gasification. spread, and then cause the fins to freeze and even the pipes to freeze, so a new gasifier is urgently needed to solve the current problems. SUMMARY OF THE INVENTION [0004] The purpose of ...
