Novel low-temperature liquid jacket finned tube type vaporization device

Abstract

A novel low-temperature liquid jacket finned tube type vaporization structure is composed of an outer tube and a finned tube arranged in the outer tube. The finned tube is composed of a first finned tube body and a second finned tube body, wherein the first finned tube body and the second finned tube body are vertically arranged, a finned tube compensation elbow is arranged at the joint of the first finned tube body and the second finned tube body, an L-shaped inner tube is formed among the first finned tube body, the second finned tube body and the finned tube compensation elbow, the outer tube is also provided with a first outer tube body, a second outer tube body and an outer tube compensation elbow which are the same as the inner tube in structure, a sampling gas outlet is formed in the first finned tube body, a sampling liquid inlet is formed in the second finned tube body, a heat source gas outlet is formed in the first outer tube body, a heat source gas inlet is formed in the second outer tube body, and tube caps are arranged at the ends of the outer tube respectively. The novel low-temperature liquid jacket finned tube type vaporization structure has the advantages of being simple in structure, high in practicability, low in cost, safe in performance, convenient to install and the like.

Description

technical field [0001] The invention relates to a novel low-temperature liquid jacketed finned tube vaporization structure, which belongs to the technical field of structure design. Background technique [0002] Driven by the rapid development of my country's coal chemical industry, petrochemical industry, electronic gas and other industries, the air separation industry has developed rapidly. critical use. As important products in the air separation industry, liquid oxygen and krypton-xenon liquids contain dangerous components such as methane, carbon dioxide, and nitrous oxide that are flammable, explosive, and easy to crystallize. Once the content exceeds the standard, it is easy to cause a safety accident. Real-time and accurate monitoring of the content of dangerous components in liquid samples has become particularly important. Contents of the invention [0003] The present invention is applied to the vaporization of low-temperature liquid, and the technical problems ...

AI Technical Summary

Problems solved by technology

[0003] The present invention is applied to the vaporization of low-temperature liquid, and the technical problems to be solved are as follows: when the low-temperature liquid is continuously sampled, the components in the liquid cannot be vaporized at the same time due to different boiling points, which in turn causes the liquid phase components in the sampling medium to concentrate or even crystallize Precipitation, final vaporization is not complete, and ultimately cannot truly reflect the content of dangerous components in the sampling liquid; the temperature of the low-temperature liquid is about -185°C, and the problem of compensation for the low-temperature cold shrinkage of the vaporized structure becomes more prominent
