Abstract

The invention relates to a wet desulphurization device forcoal bed gas. The wet desulphurization device comprises a bottom plate, an impurity removal mechanism and a desulphurization mechanism, the impurity removal mechanism comprises a spraying mechanism, a filtering mechanism and an impurity removal box, the filtering mechanism and the spraying mechanism are arranged in the impurity removal box, the spraying mechanism is located over the filtering mechanism, the desulphurization mechanism comprises a reaction box, a motor is fixedly mounted at the top of the reaction box, a shaft rod is fixedly mounted on an output shaft of the motor, stirring blades are fixedly mounted in the outer side of the shaft rod, a first mounting rod and a second mounting rod located over the first mounting rod are fixedly mounted in the outer side of the shaft rod, a scraping plate is fixedly connected between the ends, away from the shaft rod, of the first mounting rod and the second mounting rod, a partition plate is fixedly mounted on the inner side of the reaction box, and evenly-distributed air holes are formed in the top of the partition plate. According to the wet desulphurization device for coal bed gas, gas can be in full contact with chemicals, the desulphurization effect is thorough, and therefore the desulphurization efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of coal bed gas desulfurization, in particular to a coal bed gas wet desulfurization device. Background technique [0002] Coalbed methane is an unconventional energy source, its main component is methane. China has abundant reserves of coalbed methane resources. If it can be effectively utilized, it will be able to alleviate the current energy shortage situation. H2S widely exists in coalbed methane, which is toxic and harmful. Strong corrosive impurities, colorless and smell of rotten eggs, will cause deep-hole corrosion and embrittlement to metals such as iron and steel, especially harmful to the human nervous system, large amounts of inhalation will cause death and pollute the environment, so coalbed methane Before utilization, it must undergo desulfurization and purification treatment, which is not only beneficial to environmental protection, but also can effectively improve the utilization efficiency o...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a coal bed gas wet desulfurization device, which has the advantages of good desulfurization effect, etc., and solves the problem that the impurity contained in the gas cannot be processed before desulfurization, which will affect the later desulfurization reaction. efficiency, and after desulfurization, the desulfurization body will produce sediment and adhere to the inner wall of the desulfurization body, which is very troublesome and time-consuming to clean. many inconveniences
