Abstract

The invention discloses a hydrate absorption supercharging device. The hydrate absorption supercharging device comprises a hydrate generator, a hydrate decomposer, a low-temperature and constant-temperature system, a solution pump, a transfusion pipeline, a pressure reduction valve and a reflux liquid pipeline, wherein the hydrate generator is a low-pressure sealed container in which water is filled; a low-pressure gas inlet is formed on the wall of the container; the low-temperature and constant-temperature system is arranged outside the hydrate generator so as to keep the water temperature in the hydrate generator; the hydrate decomposer is a high-pressure sealed container; a high-pressure gas outlet is formed in the top of the hydrate decomposer; the transfusion pipeline and the refluxliquid pipeline are connected with the hydrate generator and the hydrate decomposer; the solution pump is arranged on the transfusion pipeline; and the pressure reduction valve is arranged on the reflux liquid pipeline. The invention also discloses a method for supercharging gas by using the device. The device has a simple structure and low cost; as a mechanical moving component is absent in the device, the device runs quietly and has advantages of small vibration, low noise and high reliability; and the invention can be applied to various systems such as chemical engineering, gas liquefaction separation, refrigeration, power and the like for realizing supercharging of the gas.

Description

Technical field: [0001] The invention relates to a gas pressurizing device, in particular to a hydrate absorption type gas pressurizing device and method for obtaining high pressure by utilizing gas hydrate to decompose and release gas when the temperature increases, belonging to the technical field of thermal energy. Background technique: [0002] In the field of engineering technology, it is often required to pressurize the gas at normal pressure. The gas compressors currently used are usually electrically driven mechanical compressors, and their working principle is fundamentally based on the change of the gas volume or the change of the speed to achieve the purpose of compressing the gas to increase the air pressure. However, this type of gas compressor will encounter many complex technical problems when the compression target pressure value is high, especially when the compressed gas is condensable gas, such as low efficiency, complex machine structure, rising cost, etc...
