Integrated type sulfur-containing waste gas purifying device

Abstract

The invention relates to an integrated type sulfur-containing waste gas purifying device comprising a monomer sulfur precipitation region, an aerobic biological sulfur-removing region and an anaerobic biological sulfur-removing region, wherein the monomer sulfur precipitation region comprises a base, sulfur discharging pipes and tapered sulfur discharging hoppers, wherein a plurality of the tapered sulfur discharging hoppers are fixed on the upper surface of the base, and the sulfur discharging pipes are arranged at the bottoms of the grooves of the tapered sulfur discharging hoppers; the aerobic biological sulfur-removing region comprises an air aerator, an overflowing box, a circulating flow guide plate and an air baffle; and the anaerobic biological sulfur-removing region is sequentially composed of a biological packing layer A, a liquid distribution device A, a biological packing layer B and a liquid distribution device B from bottom to top, wherein a sulfur-containing waste gas feeding pipe is introduced at one side below the biological packing layer A, and a waste gas collecting opening is arranged at the top of the anaerobic biological sulfur-removing region. The integrated type sulfur-containing waste gas purifying device integrates sulfur-removing bacterial culture and waste gas sulfur removing, and can efficiently and safely finish the purification work of the sulfur-containing waste gas; and the integrated type sulfur-containing waste gas purifying device has the advantages of reasonable and simple structure, convenience in machining and convenience in popularization and application.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, in particular to a one-piece purification device for sulfur-containing waste gas. Background technique [0002] Sulfur oxide is a gaseous pollutant with a large amount and a wide range of impacts among current air pollutants. There are many sources of sulfur oxides in the atmosphere, and almost all industrial enterprises may produce them, mainly from the combustion of sulfur-containing fuels (coal, petroleum). Coal is the first energy source for my country's economic development, accounting for about 70% of my country's energy consumption. The sulfur content in my country's coal is high, and a large amount of coal combustion and high sulfur content in coal lead to a large amount of SO 2 emission. SO 2 The existence of SO has caused a certain degree of harm to the natural ecological environment, human health, industrial and agricultural production, buildings and materials, etc., esp...

Problems solved by technology

In addition, as shown in Equation 2, in the case of excess oxygen, sulfide will be oxidized to sulfate, which will affect the desulfurization yield. Furthermore, how to ensure the efficient operation of desulfurization bacteria in the desulfurization device is also a difficulty in biological desulfurization technology

These deficiencies have not been effectively resolved, hindering the popularization and application of biological desulfurization technology
