Anti-freezing POC type gas cabinet

Abstract

The invention relates to an anti-freezing POC type gas cabinet, and belongs to the technical field of gas storage engineering. The anti-freezing POC type gas cabinet comprises a cabinet body and a piston which is arranged in the cabinet body and moves up and down, wherein the cabinet body comprises stand columns, side plates and T-shaped steel; an electric heating belt and a heat insulation layerare arranged on the outer wall of each side plate; heat insulation layers cover the T-shaped steel and the stand columns; and the upper part of the piston is coated with a heat insulation layer. According to the anti-freezing POC type gas cabinet, a heating heat insulation device is arranged on the outer side of the cabinet body and the heat insulation layer is arranged in the piston area, so thatsafe and stable operation of the gas cabinet in a cold area under the condition that the input heat of the gas is smaller than the heat dissipation is achieved.

Description

technical field

[0001] The invention belongs to the technical field of gas storage engineering and relates to an antifreeze POC type gas tank. Background technique

[0002] POC type gas cabinet, that is, cylindrical thin oil-sealed dry gas cabinet, also called cylindrical cabinet or new type gas cabinet, combines the cylindrical barrel structure of the Kolon gas cabinet and the lever counterweight mechanism to compress and seal The piston sealing structure with the rubber belt tightly attached to the side plate, and the advantages of high sealing safety and reliability of the thin oil of the polygonal thin oil seal gas cabinet, adopt the automatic closed-circuit forced circulation of the sealing oil to continuously supply the sealing oil to the piston oil groove, and keep the piston oil groove The height of the oil seal, together with the piston sealing device to prevent the gas from escaping, seals the gas. It has the advantages of high gas storage pressure and small fluctu...
