Automatic low-temperature cold trap water removal system

Abstract

The invention discloses an automatic low-temperature cold trap water removal system which comprises a medium-temperature-level refrigeration circulation system, a low-temperature-level refrigeration circulation system and a low-temperature liquid precise temperature control circulation system. The medium-temperature-level refrigeration circulation system and the low-temperature-level refrigeration circulation system are connected to two heat exchange pipes of an intermediate heat exchanger respectively, and the low-temperature-level refrigeration circulation system and the low-temperature liquid precise temperature control circulation system are connected to two heat exchange pipes of a low-temperature heat exchange pipe respectively. The medium-temperature-level refrigeration circulation system provides a medium-temperature environment for the low-temperature-level refrigeration circulation system through the intermediate heat exchanger, and the low-temperature-level refrigeration circulation system provides a low-temperature environment for the low-temperature liquid precise temperature control circulation system through the low-temperature heat exchanger. Automatic ice melting and automatic water drainage are achieved, a cold trap pipe does not need to be replaced, manpower and time cost is reduced, and therefore use is easy and convenient, and high practical value is achieved.

Description

technical field [0001] The present application relates to the technical field of cold trap water removal, in particular to an automatic cryogenic cold trap water removal system. Background technique [0002] When the prior art detects the greenhouse gases in the atmosphere, the greenhouse gases in the atmosphere are generally monitored through a special gas monitoring system, and the composition and content of the greenhouse gases can be accurately grasped through the monitoring system. However, since the greenhouse gas to be monitored contains a certain amount of water, the presence of water affects the detection accuracy of the gas. Therefore, before gas monitoring, it is necessary to remove water from the greenhouse gas, so that the detected gas is a dry gas and improve the accuracy of the detection value. [0003] Usually, the American FTS ultra-low temperature cold trap method is used to remove water from greenhouse gases in the atmosphere. This method is to place the ...

AI Technical Summary

Problems solved by technology

However, after the cold trap tube is used for a long time, a lot of ice will accumulate on the inner wall of the cold trap tube, which will affect the passage of gas in the cold trap tube, so it is necessary to manually replace the cold trap tube, resulting in increased labor costs

In addition, the original gas path will be disconnected when replacing the cold trap tube, which will affect the continuity of detection and cause pollution to the gas path
