Background

Industrial waste gas is a generic term for various pollutant-containing gases discharged into the air during the combustion and production processes of fuels in the factory area of an enterprise. These exhaust gases are: carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, lead mercury (mist) sulfate, beryllium compounds, smoke dust and productive dust, which are discharged into the atmosphere and pollute the air. The substances enter human bodies through different paths of respiratory tracts, some substances directly cause harm, and some substances have an accumulation effect and can seriously harm the health of people. The industrial waste gas treatment refers to the work of pre-treating waste gas generated in industrial places such as factories and workshops before the waste gas is discharged to the outside so as to reach the national standard of the external discharge of the waste gas.

The general industrial waste gas contains particulate matters, the particulate matters are also called dust, various solid or liquid particles are uniformly dispersed in an aerosol system, the particulate matters are generally impurities contained in raw materials in the industrial production process, and the impurities are not completely combusted and decomposed and are mixed in the gas in the form of smoke dust to form waste gas containing the particulate matters for emission, so that the waste gas needs to be filtered and removed in the waste gas treatment process.

The treatment of particulate pollutants such as smoke dust contained in exhaust gas is generally purified by a filtering method, but in the filtering treatment, the most common problem is that the filtering equipment is blocked due to particulate matters and is difficult to clean, so that the filtering effect of the equipment is poor, and even the normal use of the equipment is influenced.

s2, waste gas filtration: waste gas is introduced into the filter cartridge (1) through the gas inlet pipe (10), when the waste gas passes through a fibril filter layer formed by gathering the double-end adsorption filaments (8) from bottom to top, particulate pollutants in the waste gas are filtered by the fibril filter layer so as to be adsorbed on the double-end adsorption filaments (8), and the filtered waste gas is discharged from the filter cartridge (1) through the gas outlet pipe (11);

s3, adding water for cleaning: after the filtration is finished, clean water is sufficiently introduced into the filter cartridge (1) through the water inlet pipe (12), so that the liquid level of the clean water is positioned at the upper side of the double-spiral annular cartridge (2);

s4, dispersing and desorbing: starting the electric telescopic rod (9), driving the movable screen plate (4) to move up and down repeatedly, enabling the double-end adsorption wires (8) to repeatedly perform a mutual gathering, extrusion and diffusion process in water, expanding the filling gaps of the double-end adsorption wires (8), and enabling the double-end adsorption wires (8) to be mutually extruded and ground, so that particles are desorbed from the double-end adsorption wires (8);

s5, in the up-and-down moving process of the movable screen plate (4), the main limiting sliding column (6) and the auxiliary limiting sliding column (7) are respectively matched with the main spiral groove (201) and the auxiliary spiral groove (202) to move, so that the movable screen plate (4) synchronously rotates horizontally in the up-and-down moving process, water flow is driven to flow in the vertical-horizontal two directions, and desorption of particles is accelerated.
