Abstract

The invention discloses an efficient fuel gas treatment system for a boiler. The efficient fuel gas treatment system for the boiler comprises the boiler, an efficient catalytic reaction device, a demist dehydrator, an exhaust fan, a precipitation device and a slurry pump, and also comprises a water screen desulfuration dust collector, a water pump and a heat exchanger, wherein the boiler, the heat exchanger, the water screen desulfuration dust collector, the demist dehydrator, the efficient catalytic reaction device and a smoke vent are sequentially connected through a connecting pipe. The efficient fuel gas treatment system for the boiler is suitable for being widely applied to the treatment field of various tail gases. The efficient fuel gas treatment system has the advantages of being strong in adsorptivity, high in purification efficiency and wastewater utilization ratio, long in service life and the like.

Description

technical field [0001] The invention belongs to the technical field of tail gas desulfurization, and relates to a high-efficiency 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 ar...
