Boiler flue gas treatment system

Abstract

The invention discloses a boiler flue gas treatment system which comprises a boiler, an efficient catalytic reaction device, a demisting dewaterer, an exhaust fan, a sedimentation device, a slurry pump, a water screen desulfurization deduster and a water pump. The boiler, the water screen desulfurization deduster, the demisting dewaterer, the efficient catalytic reaction device and a smoke vent are connected sequentially through connecting pipes. The boiler flue gas treatment system is suitable for being widely applied to the treatment field of various tail gases, and has the advantages of high adsorbability, purification efficiency and waste water utilization rate, long service life and the like.

Description

technical field [0001] The invention belongs to the technical field of tail gas desulfurization, and relates to a boiler flue gas treatment system. Background technique [0002] At present, many cities in my country are seriously polluted by sulfur dioxide in the air. In recent years, the acid rain pollution situation in my country has not only not improved significantly, but some areas have shown an aggravating trend. According to the Bulletin on the State of the Environment in China, the total emission of sulfur dioxide in waste gas in the country is 19.266 million tons. Among them, emissions from industrial sources were 15.62 million tons, and emissions from domestic sources were 3.646 million tons. According to authoritative data, the direct or indirect loss due to acid rain in my country is as high as more than 100 billion yuan every year, and sulfur dioxide pollution is the main cause of acid rain. [0003] The main emissions from boiler combustion are sulfur dioxide...
