Problems solved by technology

Since this technology uses a medium-high temperature SCR catalyst, the temperature of the flue gas before entering the catalyst needs to be 350°C, so a fuel-fired hot blast stove is required to heat the flue gas, which will result in high operating costs and is diffi

Abstract

The invention belongs to the technical field of waste gas treatment, and particularly relates to a glass melter flue gas dust removal, desulfurization and denitrification synergetic treatment system, a treatment method and an application. The system comprises an inlet flue, a first flue gas heat exchanger, a desulfurizing tower, a dust remover, an SCR reactor, a second flue gas heat exchanger and an ammonia supply device. The ammonia supply device comprises an ammonium hydroxide storage tank, an ammonia gas evaporator, a mixer and an ammonia spraying grid, all of which are sequentially connected. Compared with an existing glass melter flue gas treatment system, the technical scheme of carrying out desulfuration, dust removal and desulfuration in sequence is adopted, the poisoning effect and blocking of harmful substances in glass melter flue gas on an SCR catalyst are avoided, and the application condition of the SCR low-temperature catalyst can be met. In addition, the SCR low-temperature catalyst is adopted, heat of original flue gas is utilized through two times of heat exchange, the whole system does not need an additional heat source, and operating cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a glass melting furnace flue gas dust removal, desulfurization and denitrification cooperative treatment system, treatment method and application. Background technique [0002] The Ministry of Environmental Protection has promulgated the "Emission Standard of Air Pollutants for Flat Glass Industry GB26453-2011" and "Emission Standard of Air Pollutants for Electronic Glass Industry GB29495-2013", and the "Emission Standard of Air Pollutants for Daily Glass Industry" is also seeking opinions Therefore, the treatment of air pollutants in glass melting furnaces has been carried out one after another. Most of the projects that have been implemented so far are in poor operating conditions, and it is difficult to meet the standard requirements. The task of air pollution control in glass melting furnaces is still extremely arduous. [0003] The flue gas of glass ...
