System for purifying flue gas by using biomass adsorption material

Abstract

The invention belongs to the field of boiler tail flue gas purification treatment, and particularly discloses a system for purifying flue gas by using a biomass adsorption material. The system comprises a boiler flue gas output module, a flue gas denitration module, a flue gas desulfurization module, a flue gas decarburization module and a chimney; the flue gas denitration module comprises a denitration body with a hollow structure inside and a denitration biomass catalytic adsorption material arranged in the hollow structure of the denitration body; the flue gas desulfurization module comprises a desulfurization body, a first bracket and a desulfurization biomass adsorption material; the desulfurization biomass adsorption material is arranged in the desulfurization body; the flue gas decarburization module comprises a decarburization body, a second bracket and a decarburization biomass adsorption material; and flue gas treated by the flue gas denitrification module, the flue gas desulfurization module and the flue gas decarburization module is discharged through the chimney. The system can effectively solve the problems that corresponding flue gas treatment equipment of a coal-fired power plant boiler is huge and high in cost, and has the advantages of being environmentally friendly, low in energy consumption and high in industrial application value.

Description

technical field

[0001] The invention belongs to the field of boiler tail flue gas purification and treatment, and more specifically relates to a biomass adsorption material purification treatment flue gas system. Background technique

[0002] With the continuous expansion of domestic industrial scale, the emission of air pollutants has increased rapidly, and the SO emitted into the atmosphere 2 , NO x , heavy metals, etc. will cause serious damage to the natural environment and human health, and the emitted CO 2 It is a greenhouse gas that causes global warming and environmental degradation. Therefore, it is imminent to deal with the tail flue gas emissions from industrial combustion represented by power plant boilers. my country attaches great importance to the environmental problems caused by flue gas emissions, and has been increasing research on flue gas emissions, especially denitrification and desulfurization, but there are still certain limitations in these fields....
