Description

Technical Field

[0001] The utility model relates to the technical field of gas, in particular to a gas preprocessor dedicated for direct combustion of low-concentration gas. Background Art

[0002] The main components of gas are alkanes, of which methane accounts for the vast majority, with a small amount of ethane, propane and butane. In addition, it generally contains hydrogen sulfide, carbon dioxide, nitrogen and water vapor, as well as trace amounts of inert gases such as helium and argon. It is an important industrial raw material and daily life fuel gas, with a lower limit of 5.3% and an upper limit of 15% in the atmosphere. In the manufacturing process of existing gas, due to variables in the production process, the concentration of the produced gas will deviate, and low-concentration gas cannot be collected and used, but direct emission will cause air pollution or be inhaled by people, causing injuries. The gas preprocessor dedicated to low-concentration gas direct combustion is a device used to treat low-concentration gas, which is designed to purify and pressurize low-concentration natural gas or other combustible gases and prepare them for direct combustion or power generation.

[0003] The pre-treatment process includes gas purification. Regardless of whether low-concentration gas is used for direct combustion or discharge, the gas will contain solid particles and impurities. If it is not purified, it may cause damage to the direct combustion equipment, such as corrosion of pipes, clogging of nozzles, etc., reducing the service life of the equipment. If it is discharged directly, the pollutants in the gas may be discharged into the atmosphere, causing environmental pollution and adversely affecting the surrounding environment and ecosystem.
