Desulfurization and denitrification afterheat power generation systematization device of glass melter flue gas

Abstract

The invention discloses a desulfurization and denitrification afterheat power generation systematization device of glass melter flue gas. The desulfurization and denitrification afterheat power generation systematization device comprises the process that: a. a fourth flashboard (14) is arranged in an afterheat boiler (15), a high-temperature section (6) and a low-temperature section (5) are formed, a bypass flue (9) of a chimney (7) is connected with the high-temperature section (6), and an exhaust pipeline of the low-temperature section (5) is connected with the chimney (7); b. the high-temperature section (6) is provided with a bypass pipeline and connected with a dry desulfurization reactor (3), a high-temperature electric dust remover (2) and a denitrification reactor (1), and c. the denitrification reactor is connected with the low-temperature section (5) through the pipeline. The desulfurization and denitrification afterheat power generation systematization device has the beneficial effects that: high-temperature flue gas firstly passes through the high-temperature section of the afterheat boiler, and the temperature of the flue gas is reduced, so that electrode material of an ESP (electrostatic precipitator) does not need to adapt to over-high temperature, and the requirements of an SCR (selective catalytic reductor) denitrification system on the temperature can be met. The flue gas enters the low-temperature section of the afterheat boiler again after being desulfurized and dedusted, so that the afterheat of the flue gas is fully and effectively recovered.

Description

Technical field [0001] The present invention involves environmental protection technology fields, especially for desulfurization and denitrification and residual heat generation devices of glass melting kiln flue gas. Background technique [0002] Glass melting kiln is an industrial kiln with high resource consumption, high pollutant emissions and high energy consumption.During the production process of flat glass in my country, it mainly uses heavy oil as a fuel. The molten kiln flue gas emissions caused serious air pollutants. The main pollutants are particulate matter, SO, SO 2 And NO x EssenceAfter years of independent development, the technique of glass foam dumplings has gradually matured, and smoke and SO 2 Pollution has been controlled.However, most of the domestic flue gas desulfurization technologies are mostly wet tobacco desulfurization. The wastewater generated by desulfurization needs to be further treated. The use rate of waste residue generated by desulfurization ...
