Circular suspension type semi-dry fume purifier

Abstract

The fume cleaning equipment possesses an inverted spray-drying desulfurizing tower, the lower portion of one end of said desulfurizing tower is equipped with water atomizing nozzle, slurry atomizing nozzle, venturi air-distributing device and ash valve, the other end of the desulfurizing tower is connected with dust remover, the other end of said dust remover is connected with induced fan, and the outlet of bottom of the dust remover is connected with fan and feeding injection pump, and is connected with underside of water atomizing nozzle in lower portion of the desulfurizing tower, the slurry atomizing nozzle is connected with air compressor and sturry metering feeding equipment. Said product is simple in structure, also can remove other harmful gas and heavy metal, etc.

Description

technical field [0001] The invention relates to a circulating suspension semi-dry flue gas purification device. Background technique [0002] With the development of industry, my country's SO 2 The emission of high acid rain has caused serious acid rain in many areas, and the average economic loss caused by it is more than 100 billion yuan. In order to solve the current air pollution problem, my country has formulated stricter SO 2 Pollution control laws and regulations, according to the "Reply of the State Council on Relevant Issues Concerning Acid Rain Control Areas and Sulfur Dioxide Pollution Control Areas" (State Council [1998 No. 75] document requirements, in 2000, the national SO 2 Pollution emissions are less than 16 million tons, and the air quality of the municipalities, provincial capitals, open cities and key tourist cities in the "two control areas" meets the national environmental quality standards, and measures to limit high-sulfur coal mining, develop desul...

AI Technical Summary

Problems solved by technology

[0003] At present, foreign desulfurization technology is relatively mature, but the price of desulfurization equipment is quite expensive, and its operation cost is also very high, so that it cannot be popularized and applied on a large scale in my country

Taking Luohuang Power Plant as an example, the investment cost of flue gas desulfurization equipment is 300 million yuan, and the annual operation cost of flue gas desulfurization can reach more than 40 million yuan. Therefore, foreign desulfurization equipment generally has the problem of not being able to build or operate in my country.
