Description

Water bath turbulent mixed jet flue gas purification equipment

technical field

The invention relates to the technical field of purification equipment, in particular to a water bath turbulent mixed jet flue gas purification equipment.

Background technique

Dust is one of the main sources of air pollution. As the fuel structure in my country is still dominated by coal, the air pollution in my country is dominated by soot-type pollution. Among them, dust and acid rain are the most harmful. Therefore, controlling the emission of dust and sulfur dioxide will improve the atmosphere Contamination status is critical. At present, the development of dust removal technology is relatively complete, mainly including bag type dust removal, mechanical dust removal, electrostatic dust removal and wet dust removal; among them, there are bag type, cyclone type, electrostatic type, water film type, spray type, water bath type and other dust removal technologies. The first three types only have the function of dust removal and cannot eliminate harmful gases. The latter three types of technologies belong to wet dust removal, which has the functions of dust removal and filtering harmful gases, but the dust removal efficiency is relatively low, and it is difficult to achieve ultra-low emission standards. In recent years, although these technologies have been improved, they have not been separated from the original technical principles. Therefore, there has been no major breakthrough in technology. Other technologies such as spraying, spraying and adding cloth bags imported from abroad (the United States, Japan and other countries) have no new breakthrough in principle, and the cost of the equipment used is also very high. The future development direction of fog removal and dust removal technology is mainly to improve efficiency and reduce energy consumption, and the technology of the present invention conforms to the current development trend and has a wide range of adaptability, and is an updated product of current fog removal and dust removal technology.
