Embodiment Construction

[0012] The present invention will be described in further detail below by way of examples.

[0013] Such as figure 1 As shown in FIG. 3 , a method for purifying gas by filtering liquid-phase medium, there is a liquid-phase medium in the lower part of the outer cylindrical shell 6, and the liquid-phase medium will be continuously replenished. 1 There is a distance at the bottom, the filtered gas enters the outer shell 6 from the intake pipe 1, and impacts the liquid phase medium at the lower part of the outer shell 6 through the diversion cone 3, the liquid splashed from the bottom and the filtered gas are in the process of rising The mixed slurry passes through the refinement flow hood 4, so that the liquid medium forms a dynamic liquid medium filter layer on the refinement orifice plate 4-1, and at the same time, the filtered gas is divided into countless extremely fine gas columns. The column passes through the liquid medium filter layer on the refined orifice plate 4-1 for...

Abstract

A liquid medium filtering method for cleaning gas includes such steps as introducing the raw gas to inside of external cylindrical casing via gas inlet tube, flowing through guide cone to impact the lower liquid medium while mixing the raw gas with the splashed liquid to become slurry, passing through fining cover, generating a dynamic liquid medium filter layer on a perforated fining plate while dividing the raw gas into innumerable fine gas columns, passing through the perforated plate for filtering and washing, and de-moistening.

Description

technical field [0001] The present invention relates to a liquid-phase medium filter gas purification method and its device, in particular to a method applicable to dust removal and desulfurization of boiler flue gas, air purification and sterilization in public places such as hotels and hospitals, and hydrogen sulfide gas and coal in fertilizer plants. Gas purification method and device for liquid-phase medium filtration gas purification in the process of dust particles, oil fume gas purification in restaurant canteens, capture and elimination of dust and gas gas in coal mine underground operations, etc. in many industries and fields. Background technique [0002] At present, there are many kinds of gas purification methods and matching purification equipment. In various traditional methods of spraying the gas to be treated with a liquid medium (filtering waste gas, purifying air, etc.), the filtered gas to be treated is generally used. After the gas enters the processing c...
