Problems solved by technology

The former makes insufficient use of low-pressure gas, while the latter is likely to damage the life of the internal combustion unit and increase unsafe factors
[0004] At the same time, the dust in the gas will also cause blockage of the flame arrester in the pipeline, and also cause wear and tear on the cylinder of the internal combustion engine, and the gas needs to be dedusted
As a flammable and explosive gas, low-concentration gas cannot use conventional static electricity or other dry dust removal methods, while general wet dust removal occupies a large area, has poor dust

Abstract

The invention relates to a high-efficiency energy-saving pretreatment process used for generating gas. The invention relates to a high-efficiency energy-saving pre-treatment method for generating gas. The method employs a dedusting, dehumidification and supercharging machine and integrated equipment to dedust, dehumidify and supercharge the gas sent to a generator set. The method has the advantages of high dehumidification efficiency, energy saving, and high efficiency of dust removal, and maximum dust particle size of from the outlet is not greater than 1.5 [mu]m, and pressurization mixing pressure is adjustable. By adopting the process method of the invention, pretreatment of gas is carried out, efficient utilization of resources can be satisfied, operation cost is reduced, and energy is saved and cost is reduced.

Description

technical field [0001] The present invention relates to a pretreatment process for power generation gas, specifically including the process of dehumidifying, pressurizing and dedusting the gas sent to the generator set by using a dust removal, dehumidification and pressurization integrated machine and supporting assembly equipment. It belongs to the field of chemical industry and energy. Background technique [0002] When mineral gas is used for power generation, the temperature of the extracted gas will rise and contain saturated water vapor and free water because it is extracted and transported by a liquid ring vacuum pump. There is spray water, which makes the gas have a high moisture content before entering the generator set, which cannot meet the humidity requirements of the generator set. Because the high water content in the gas not only affects the thermal power conversion efficiency of the unit, but also accelerates the emulsification of the lubricating oil to caus...
