Abstract

The invention discloses a tank interlayer low-temperature adsorption device and a working method. The tank interlayer low-temperature adsorption device comprises an adsorbent filling unit, an adsorbent activation assembly and an adsorbent sealing and storing assembly; the adsorbent filling unit comprises a closed whole formed by welding a manhole shell ring, a process seal head, a metal seal plate, a lower connecting flange and an adsorbent filling pipe; the adsorbent activation assembly comprises a heat preservation heating box, an upper connecting flange, a first pipeline, a second pipeline,an inflation stop valve, a vacuum butterfly valve, a vacuum pump and a nitrogen cylinder; and the adsorbent sealing and storing assembly comprises a rupture disk capable of being arranged on an upperpipe opening of the adsorbent filling pipe, a flange plate capable of being arranged on the lower connecting flange, a perforated metal plate capable of covering the upper surface of the flange plate, and a fastener capable of connecting the perforated metal plate, the flange plate and the lower connecting flange. The tank interlayer low-temperature adsorption device is a low-temperature adsorption device integrating an adsorbent activation function and a low-temperature adsorption function, and can ensure that the adsorbent plays an efficient role; and by means of the invention, the vacuum service life of the container interlayer can reach 5 years.

Description

technical field [0001] The invention belongs to the field of vacuum interlayer treatment of heat-insulating containers, and relates to a tank interlayer low-temperature adsorption device and a working method. Background technique [0002] Ensuring long-lasting and good vacuum performance is the basic guarantee for the normal operation of high-vacuum multi-layer insulation cryogenic containers. During the use of high-vacuum multi-layer heat-insulated cryogenic containers, due to the outgassing of the interlayer material of the container and the leakage of air from the external environment to the interlayer, the vacuum degree of the container will inevitably decrease; The placed adsorbent (such as molecular sieve, activated carbon, etc.) adsorbs the gas existing in the interlayer, so as to maintain the vacuum performance of the container. Under normal circumstances, it is hoped that the adsorbent will work again after the moisture and impurity gases in the interlayer are remo...
