Method for avoiding freezing up of base soil of cryogenic storage tank
Date: Mar 19, 2020
The production of storage tanks adopts an internal thermal insulation structure design, which has higher thermal insulation performance and reliable performance than traditional structures. The independent innovation of vacuum pumping process and vacuum helium mass spectrometry leak detection can ensure that the storage tank has a long vacuum life and a static evaporation rate. Higher than industry standard requirements.
According to different process requirements and media storage methods, cryogenic tanks can be divided into three types of tanks: single-container, double-container and full-container. The single container tank is generally composed of a steel inner tank and a thermal insulation shell, while the double container tank and the full container tank are composed of a steel inner tank and a steel or concrete outer tank. Between the inner and outer tank walls, the double tank method is currently the most commonly used method.
Cryogenic storage tank is a vertical or horizontal double-layer vacuum insulation tank for storing liquid oxygen, nitrogen, argon, carbon dioxide and other media. Its main function is to fill and store cryogenic liquid. Therefore, the requirements for the manufacture and construction of cryogenic storage tanks are relatively high. Among them, avoiding the phenomenon of frost rise during planning is a factor we must consider.
When planning a cryogenic tank, due to the conductive effect of the low-temperature medium in the tank, the foundation soil is prone to frost and swell, which will cause the foundation to break. Therefore, in order to eliminate this unfavorable factor, in addition to the surface of the tank bottom and bottom In addition to heat preservation methods, anti-freezing measures must be taken on the root of the tank. There are two common methods. One is to use electric or other heating systems in the bottom of the root to make a raft-type root with a circulating heating system. The first method is to choose the foundation floor to be elevated and separate the foundation floor from the foundation soil by the air layer formed by the overhead.
