Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to an environmental protection dust removal and desulfurization equipment. Background Art

[0002] Flue gas is a mixture of gas and smoke, and is the main cause of atmospheric pollution in residential areas. The composition of flue gas is very complex. Gases include water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons and nitrogen oxides, etc. Smoke includes fuel ash, coal particles, oil droplets and high-temperature cracking products, etc. Flue gas contains a large amount of toxic gases (CO, SO2). At the same time, suspended particulates in flue gas are also harmful. The smaller dust particles in the suspended particles can enter the human lungs due to gas diffusion, adhere to and accumulate on the alveolar wall, and can be transported to the whole body with the blood, causing respiratory diseases. Therefore, the flue gas generated by modern industry needs to be dust-removed and desulfurized, and strictly controlled before it is allowed to be discharged.

[0003] In the prior art, when ammonia water is used for desulfurization and dust removal, the sulfur-containing gas usually has a short retention time after entering the treatment equipment, causing the gas to flow out quickly, resulting in insufficient contact between the sulfur-containing gas and the ammonia water, resulting in the sulfur-containing gas being unable to be fully removed, thereby causing corresponding hazards and affecting the overall treatment effect. In addition, dust particles accumulated inside the equipment will sink to the bottom of the water and are difficult to clean. If personnel manually handle it, it will not only pose a threat to their health but also increase their labor intensity, and the use effect is not very ideal. Utility Model Content
