Environmental protection device for dedusting and desulfurizing smoke

Abstract

The invention relates to the technical field of environmental protection devices, and discloses an environmental protection device for dedusting and desulfurizing smoke. The device comprises a dedusting tower, the bottom end of one side of the dedusting tower is fixedly connected with a smoke introduction tube, an exporting tube is fixedly mounted at the top of the dedusting tower, a connecting threaded groove 1 is arranged on the external of one end, away from the dedusting tower, of the exporting tube, and a sealed connecting groove 1 positioned at one end, away from the dedusting tower, ofthe exporting tube is arranged at the inner side of the connecting threaded groove 1. The number of inner casings is same to the total number of pipelines in the environmental protection device for dedusting and desulfurizing smoke, so the inner casings can effectively protect the inner walls of the pipelines in the working process of the device to make scales formed by corrosion and condensationattached to the inner walls of the inner casings, and the inner casings have a detachable function, so the convenience and the high efficiency of pickling and cleaning of a pipeline assembly in the device are further improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to environmental protection equipment for flue gas dedusting and sulfur removal. Background technique [0002] With the rapid development of the economy, metallurgical steelmaking electric furnaces and boilers fueled by raw coal have increased a lot. The air pollutants emitted by these furnaces have caused great harm to the surrounding environment. Therefore, the technology of dedusting and desulfurizing the gas discharged from the furnaces It is becoming more and more important. Dust removal refers to: technical measures to remove particulate matter from dusty gas to reduce its emission to the atmosphere; The desulfurization process is one of the important technical measures to prevent and control air pollution. The common equipment for dust removal and desulfurization of industrial waste gas is mainly dust removal and desulfurization tower. The dust remo...

AI Technical Summary

Problems solved by technology

[0013] Aiming at the deficiencies of the technology in the above comparative examples, the present invention provides an environmental protection equipment for flue gas dedusting and desulfurization, which can effectively prevent fouling on the inner wall of the pipeline, enable the pipeline to be connected and assembled in real time, and can clean the dust after spraying and dedusting. The advantages of gas diversion and export solve the common environmental protection equipment for dust removal and desulfurization of flue gas. Because there is no structure that can protect the inner wall of the pipeline, a large amount of scaling occurs on the inner wall of the pipeline, which greatly increases Difficulty in pickling and scaling cleaning work, because the connecting pipeline does not have a structure that can be easily disassembled and assembled, making it difficult for the equipment to conduct real-time assembly and assembly of the pipeline according to the actual length of the pipeline during the actual dust removal and desulfurization work. At the same time, it further increases the difficulty of pickling and cleaning the pipeline in the later stage, because it does not have a structure that can divert and synchronously export the gas after spraying and dust removal, thus greatly reducing the efficiency of the export work.
