Description

Technical Field

[0001] The utility model relates to the technical field of waste gas desulfurization and cleaning, in particular to a filtering, desulfurization and cleaning device for sulfur-containing industrial waste gas. Background Art

[0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during fuel combustion and production processes within the factory area of ​​an enterprise. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist), lead and mercury, beryllium, smoke and production dust, which are discharged into the atmosphere and pollute the air. These substances enter the human body through different respiratory tracts. Some of them directly cause harm, while others have an accumulation effect, which will more seriously endanger human health. Different substances will have different effects, among which sulfide waste gas has the highest degree of pollution. Therefore, in modern industrial production, the premise of waste gas treatment is to perform desulfurization and cleaning operations on it.

[0003] However, when the existing industrial waste gas desulfurization cleaning device is cleaning the waste gas, the waste gas is usually directly introduced into a desulfurizable cleaning agent, the sulfur-containing substances and sulfides are reacted in the cleaning agent, and the gas after the reaction is discharged for other purification operations and then discharged to the outside. However, the industrial waste gas contains a lot of dust. If it is directly introduced into the cleaning agent for cleaning, the squeezing between the dust will cause insufficient contact between the sulfide and the cleaning agent, affecting the desulfurization effect. At the same time, when the dust flows in the device, it is easy to cause blockage of the air inlet and outlet ends, affecting the normal air intake cleaning of the device, thereby reducing the practicability of the device.
