Improved smoke removal purifier

Abstract

The invention discloses an improved smoke removal purifier, which comprises a purification tower, wherein the purification tower comprises an oxidation pond containing absorption solution and an air bubbling component, and a smoke removal purification section containing at least two groups of absorption solution sprinkling components and at least one group of defoaming components; and particularly, the purification tower also comprises a group of washing sprinkling components for purifying flue gas and at least one group of flue gas washing section of a flue gas defoaming component. The washing section is connected with a washing circulating tank, and washing solution is also used for flushing the defoaming components of the smoke removal purification section. Thus, slurry droplets carried by the flue gas after purification are washed in the flue gas washing section and enter the washing solution, the concentration of the slurry droplets is greatly diluted and reduced, even certain droplets are carried out by the flue gas in the flue gas washing section, obvious white spots and equipment corrosion are hardly generated by the droplets, and the problem of the content increment of sulfate rain and smoke dust is solved.

Description

technical field

[0001] The invention relates to an improved smoke exhaust purification device, in particular to a flue gas desulfurization device, and belongs to the technical fields of electric power, metallurgy, environmental protection and chemical industry. Background technique

[0002] Acidic gaseous harmful substances contained in flue gas, especially SO 2 is the main source of acid rain. As we all know, one way to solve acid rain pollution is flue gas desulfurization. At present, the main method used is to produce gypsum with limestone as raw material, which is called the calcium method. Because gypsum is not very useful, the desulfurization product gypsum is often discarded and piled up, occupying cultivated land, and causing new environmental problems. Due to its cheap and easy-to-obtain raw materials, it is still the main flue gas desulfurization method. Another promising method is to use ammonia as raw material, and the desulfurization product is ammonium sulfa...
