Problems solved by technology

However, the heat of the main flue is not fully utilized, the heat will still be lost from the main flue, and the heat of the flue gas cannot be effectively used
Moreover, the current treatment of boiler flue gas in the market is mainly focused on recovering the energy in it, and the harmful particulate matter and harmful gas components in the flue gas are not well removed, resulting in environmental pollution caused by the emission of flue gas

Abstract

The invention discloses a boiler flue gas treatment device for an oil refinery. The boiler flue gas treatment device comprises a chimney hood (1), a water jacket (5), a cyclone (6), a strainer (7), an exhaust fan (8), an activated carbon filter (9) and a slag charge collector (11), and is characterized in that the chimney hood (1) is connected with the cyclone (6) through a pipeline; the cyclone (6), the strainer (7), the exhaust fan (8) and the activated carbon filter (9) are connected sequentially; and the bottoms of the cyclone (6) and the strainer (7) are connected with the slag charge collector (11) respectively. The boiler flue gas treatment device can recover energy from waste heat in flue gas and purify suspended particles, dust, harmful gas and the like, so that emission of harmful substances in the flue gas is reduced, and energy saving and emission reduction are realized.

Description

technical field [0001] The invention relates to the field of oil refinery clean production equipment, in particular to a refinery boiler flue gas treatment device. Background technique [0002] Boilers using waste oil as fuel are widely used in the petrochemical industry, but most of the flue gas produced by the boiler combustion is directly discharged, which will discharge a large amount of heat and dust, which not only wastes energy but also pollutes the environment. At present, equipment for energy recovery of boiler waste flue gas is not uncommon, such as [Patent No.] CN201320500198, [Name] a heat-saving heat pipe waste heat recovery boiler system, [Notice No.] CN203464310U, the invention discloses a heat-saving heat pipe The waste heat recovery boiler system includes a boiler, a chimney, and a main flue from the smoke outlet of the boiler to the chimney. The main flue is provided with a heat pipe heat exchanger, and the heat pipe heat exchanger is connected to the boile...
