External silver zeolite adsorption plant for low-temperature tank

Abstract

The invention relates to an external silver zeolite adsorption plant for a low-temperature tank. The external silver zeolite adsorption plant comprises a box body, silver zeolite granules and an electric heating device, wherein an opening of the box body is communicated with an interlayer of the tank, and is welded on a shell of the tank, and a portable electric heating device capable of surrounding the box body for heating is adopted as the electric heating device. According to the invention, the silver zeolite granules are filled in the box body on the outer wall of the shell of the low-temperature tank, therefore, low-temperature heating can be carried out on fiber asbestos paper and high-temperature activation can be carried out on the silver zeolite granules completely according to corresponding required optimum temperature while vacuumizing, so that best performances can be achieved; the external silver zeolite adsorption plant can completely activate silver zeolite, and can also avoid weathering risk of fiber asbestos paper so as to obviously improve the heat-insulating property of the tank; moreover, the external silver zeolite adsorption plant has the advantages of simple and reasonable structure, safety and convenience in use and the like, and is suitable to be mounted on the lower-temperature tank for use.

Description

Technical field [0001] The invention relates to a low-temperature container, in particular to a silver zeolite adsorption device that can maintain the vacuum degree in the interlayer of the low-temperature container for a long time, absorb moisture and remaining gas in the interlayer, and can significantly improve the thermal insulation performance of the low-temperature tank. The device belongs to the low-temperature tank Body accessories. Background technique [0002] With the development of human science in cryogenic technology, various cryogenic equipment has made great strides in the past ten years, especially fixed, high-vacuum multilayer winding low-temperature insulation containers and low-temperature automobile tanks, Low-temperature tanks such as low-temperature box tanks and low-temperature trailer tanks have brought us a lot of convenience in production and scientific research. At the same time, how to ensure that these cryogenic equipment maintain high vacuum for a l...
