Electric bag composite dust remover and processing method thereof

Abstract

The invention discloses an electric bag composite dust remover and a processing method thereof. The processing method comprises the steps of dissolving 3-4 parts of tetrabutyl titanate in 5-6 parts ofabsolute ethanol according to a volume ratio, continuously stirring and adding 2-3 parts of a stabilizer to prepare a solution A; adding 2-3 parts of a precious metal precursor reagent to 13-15 partsof ethyl ether according to a volume ratio, stirring continuously, adding 3-5 parts of a penetrant to prepare a precious metal solution B; adding the solution A into the solution B, stirring uniformly to form a solution C; immersing a filter bag in the solution C for vacuum impregnation; drying the impregnated filter bag, performing heat treatment, and cooling to obtain a precious metal-loaded filter bag. According to the processing method, the precious metals are loaded on the filter bag of a bag-type dust remover by methods of impregnation and the like. In the process of dust removal, the precious metals loaded on the filter bag can be used in denitration of flue gas by catalysis action to achieve dust removal and denitration of the flue gas at the same time. The precious metal materials can overcome the disadvantage that the vanadium-based catalyst is toxic.

Description

technical field [0001] The invention relates to the technical field of atmospheric dust removal, and more specifically relates to an electric bag composite dust collector and a processing method. Background technique [0002] The pollution of NOx to the atmospheric environment has become a global environmental problem. Selective catalytic reduction technology (SCR) is the most widely and most effective technology for removing nitrogen oxides in flue gas today. At present, most of the technological processes of flue gas treatment technologies adopted by coal-fired power plants in my country are denitrification first, dust removal, and desulfurization at last. This process has certain problems in practical engineering applications. In actual industrial applications, the SCR reactor is usually arranged before the dust collector. A large amount of dust in the high-temperature flue gas will form ash piles on the surface of the catalyst, causing blockage and wear of the catalyst, ...
