Purification device used for removing solid and liquid impurities in gas

Abstract

The invention discloses a purification device used for removing solid and liquid impurities in gas, which comprises an air inlet, an air outlet, a cylinder body and a filtering assembly arranged in the cylinder body, wherein the cylinder body is divided into an upper cylinder body and a lower cylinder body by a partition board; the air inlet is arranged on the lower cylinder body; the air outlet is arranged above the upper cylinder body; the top end of the upper cylinder body is provided with a filtering assembly mounting and dismounting hole; the filtering assembly is arranged in the upper cylinder body; the filtering assembly comprises a filtering element and a filtering element fixing device; and a high-efficiency cyclone separator and a gravity settling chamber are arranged in the lower cylinder body. The purification device used for removing the solid and liquid impurities in the gas has triple separating effect, i.e. gravity settling separation, high-efficiency cyclone separation and high-efficiency multilayer precise filtering separation, and therefore, the purification device has good filtering effect and high pollutant carrying capacity; moreover, the filter cylinder has convenient and fast replacement, stable structure and high reliability.

Description

technical field [0001] The invention relates to a gas-solid or gas-liquid separation device, in particular to a purification device for removing solid-liquid impurities in high-pressure natural gas. Background technique [0002] As we all know, the filter separator uses a porous body to remove dispersed solid particles from the gas. The filter mechanism mainly includes inertial collision, interception, diffusion and static electricity. Superior separation performance than other types of dust collectors. [0003] At present, cartridge filters are usually used in the filtration system of traditional natural gas purification devices, but ordinary cartridge filters are only suitable for natural gas with less impurities. Impurities such as dust and dust adhere to the pipe wall, and due to the erosion and corrosion of long-distance pipelines by high-flow gas, a large amount of dust often flows into the filter instantaneously, resulting in the filter cartridge being unable to with...

Problems solved by technology

[0003] At present, cartridge filters are usually used in the filtration system of traditional natural gas purification devices, but ordinary cartridge filters are only suitable for natural gas with less impurities. Impurities such as dust and dust adhere to the pipe wall, and because of the erosion and corrosion of long-distance pipelines by high-velocity gas, a large amount of dust often flows into the filter instantaneously, resulting in the filter cartridge being unable to withstand a large pressure difference. The damage and deformation will endanger the follow-up precision equipment. It is obvious that the filter in the traditional natural gas purification device has too little dirt holding capacity, and the filter cartridge needs to be replaced frequently; at the same time, the filter cartridge has poor tolerance and is easy to be damaged by pressure.
