Float glass melting furnace flue gas waste heat utilization and denitrification purification treatment device

Abstract

The invention relates to a floating glass melting furnace flue gas waste heat utilization and denitration purification treatment device including a waste heat boiler, a desulfurization tower connected with the waste heat boiler, and a dust remover connected with the desulfurization tower; the waste heat boiler is internally provided with an inner baffle plate for dividing the waste heat boiler into a first hot section and a second hot section; an inlet of the first hot section is connected with a glass melting furnace flue gas discharge port, an outlet of the first hot section is connected with a denitration reactor, and an outlet of the denitration reactor is connected with an inlet of the second hot section; an outlet of the waste heat boiler is connected with an inlet at the bottom of the desulfurization tower, an outlet at the top of the desulfurization tower is connected with the desulfurization dust remover, and the desulfurization dust remover is connected with a chimney through a draught fan. The waste heat boiler is divided into the first hot section and the second hot section by the inner baffle plate, the first hot section and the second hot section can be connected or cut off, and heat exchange is carried out in the waste heat boiler according to different temperatures of flue gas, and thus waste heat utilization is completed; the temperature of the flue gas entering the denitration reactor can be reduced through the waste heat boiler, so as to avoid the temperature of the flue gas in the denitration reactor from being too high and avoid the denitration efficiency from being affected.

Description

technical field [0001] The invention relates to a flue gas treatment device of a float glass melting furnace, in particular to a waste heat utilization and denitrification purification treatment device of the flue gas of a float glass melting furnace. Background technique [0002] The wet method (lime-gypsum method) is currently the most commonly used desulfurization technology in power, chemical and other industries. This method has obvious advantages and disadvantages: a. High desulfurization efficiency (desulfurization rate is as high as 95%), but the system is prone to corrosion and blockage And other phenomena, the operation is more complicated, and the maintenance workload is larger. b. The material in the whole system is in the form of slurry. The pulping, spraying system and demister are prone to fouling and clogging. The process is complex and the system management and maintenance costs are high. c. The system is complex, occupies a large area, and requires relativ...
