Boiler flue gas purification and desulfurization device

Abstract

The invention discloses a boiler flue gas purification and desulfurization device comprising a desulfurization liquid inlet, an inclined flue, a nozzle, a liquid separating baffle, and a flue outlet.The boiler flue gas purification and desulfurization device is characterized in that flue gas discharged by a boiler is sent into a desulfurization tower from a flue gas pipeline under the action of an induced draft fan, when the flue gas passes through the flue, a desulfurization liquid is sprayed by the nozzle, and sulfide in the flue gas is neutralized by the sprayed desulfurization liquid andthen flows into the desulfurization tower along the inclined flue outlet. The boiler flue gas purification and desulfurization device has the advantages: firstly, the device is highly efficient in design, convenient to use and obvious in desulfurization effect, and the desulfurization efficiency is greatly improved; secondly, the device is simple in structure, easy to manufacture and install, andgood in economical efficiency; and thirdly, the device is reasonable in design, a wall face of a pipeline at a connection part of the flue and the desulfurization tower is inclined inwards, and liquidbackflow is effectively avoided so as to prevent blockage of the pipeline.

Description

technical field [0001] The invention relates to a boiler flue gas purification and desulfurization device, which absorbs impurities and sulfides produced in the flue gas by spraying desulfurization liquid through nozzles, so as to achieve the purpose of desulfurization and purification of the flue gas. Background technique [0002] At present, coal-fired boilers are still the main fields in power generation and heating industries, and coal-fired boilers will produce a large amount of smoke and dust mixed gases, including ash and sulfides that cause environmental pollution and endanger ecology; while the flue gas purification and desulfurization of boilers today Efficiency is still not satisfactory. Therefore, it is of great significance to set up purification and desulfurization devices for coal-fired boilers. Contents of the invention [0003] The object of the present invention is to provide a flue gas desulfurization device for a coal-fired boiler, so as to reduce poll...
