Abstract

The invention discloses a boiler smoke treatment device. The boiler smoke treatment device comprises a heat recovery device, a filter box and a dust box. The air inlet end of the heat recovery deviceis connected with a smoke discharging pipe of a boiler through a pipe, and the air outlet end of the heat recovery device is connected with a smoke inlet mechanism through a pipe. The smoke inlet mechanism is connected with the upper end of the dust box, and a dust hopper is integrally arranged at the lower end of the dust box. A first electric valve is arranged at a lower end opening of the dusthopper, and a lower end opening of the first electric valve is covered with a dust collection box. Through the arrangement of the heat recovery device, waste heat in smoke is effectively recovered, and a good heat recovery effect is achieved; and a dispersion mechanism is arranged to disperse smoke in clear limewater, so that the reaction speed of sulfur dioxide in smoke and the limewater is greatly increased, the smoke desulfuration effect is improved, and a deposition tank can collect deposited dust and is convenient to disassemble and clean.

Description

technical field [0001] The invention relates to the technical field of flue gas dust removal, in particular to a boiler flue gas treatment device. Background technique [0002] The fuel used in the combustion of existing boilers is mostly coal or pulverized coal, and a lot of smoke will be produced when coal or pulverized coal is burned, and there are a lot of dust and harmful gases in these flue gases. A large amount of dust and harmful gases in the air will cause serious air pollution, and the sulfur dioxide in the flue gas will cause acid rain and seriously damage the environment. [0003] Existing flue gas treatment devices for boilers have low treatment efficiency for the dust in the flue gas, and the recovery effect of the waste heat in the flue gas is not good, and it is inconvenient to clean the dust precipitated by the dust spraying treatment, and at the same time cannot It is very good to realize the treatment of sulfur dioxide in the flue gas.
