Abstract

The invention discloses a gas-liquid separation and backheating device of a low-temperature refrigeration system. The gas-liquid separation and backheating device of the low-temperature refrigerationsystem comprises a shell, an upper sealing head and a lower sealing head. The upper sealing head and the lower sealing head are arranged on the upper portion and the lower portion of the shell correspondingly, a cavity structure is formed by the shell, the upper sealing head and the lower sealing head, the upper portion of the upper sealing head communicates with an upper bend, the bottom of the lower sealing head communicates with a lower bend, and the lower bend communicates with a throttling capillary pipe. A gas return pipe is coiled on the inner wall of the shell, the lower end of the gasreturn pipe stretches out of the shell from the position close to the lower sealing head, and the upper end of the gas return pipe penetrates out from the upper portion of the shell and extends upwards.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a gas-liquid separation and heat recovery device of a low-temperature refrigeration system. Background technique [0002] Mixed refrigerant is composed of a mixture of gas and liquid. The temperature of the mixed refrigerant rises after cooling, and it can cool itself if the temperature drops. At present, the mixed refrigerant refrigeration is not used after self-cooling is completed, and new mixed refrigerant is added continuously, which causes the cooling capacity to be lost and the self-cooling effect is not good. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention provides a gas-liquid separation and heat recovery device for a low-temperature refrigeration system. [0004] The gas-liquid separation and heat recovery device of the low-temperature refrigeration system, including the shell, the upper head and the l...
