Sintering mixer flue gas dedusting and whitening device

Abstract

The invention discloses a flue gas dedusting and whitening device of a sintering mixer. The device comprises a condensation rotational flow water collecting device connected with a sound wave agglomeration dust removing device. The sound wave agglomeration dust removal equipment comprises an equipment shell, one end of the equipment shell is provided with an equipment inlet; wherein one end of theequipment shell is provided with an equipment inlet, the other end of the equipment shell is provided with an equipment outlet, a sound wave descaling module is arranged on the equipment shell at theequipment inlet, at least a first agglomeration module or a second agglomeration module is arranged in the equipment shell, and the first agglomeration module comprises a first washing assembly and afirst dust removal assembly which are sequentially arranged in the direction from the equipment inlet to the equipment outlet; and the second agglomeration module comprises a seed particle generationassembly, a sound wave agglomeration assembly, a second washing assembly and a second dust removal assembly, which are sequentially arranged in the direction from the equipment inlet to the equipmentoutlet. The device provided by the invention solves the problem of high dust emission of the flue gas of the sintering mixer and the problem of smoke plume emission of diffused flue gas by utilizingthe combination of the sound wave agglomeration dust removal equipment and the condensation rotational flow water collection equipment.

Description

technical field [0001] The invention belongs to the field of metallurgy, and in particular relates to a sintering mixer flue gas dedusting and whitening device composed of a sonic agglomeration dedusting device and a condensing cyclone water collection device. Background technique [0002] With the development of society and the advancement of science and technology, the demand for steel industry has increased significantly. As the country pays more and more attention to environmental protection awareness. As the emission standards of the iron and steel industry and the coal chemical industry are getting higher and higher, the State Environmental Protection Agency requires enterprises to save energy and reduce emissions to protect a green China. [0003] At present, the iron and steel industry applies the mixer system to mix raw materials. The mixer system is mainly responsible for the humidification and mixing of the sinter mixture. During the production process, the mixtu...

Problems solved by technology

The disadvantage of this mixing method is that calcium hydroxide will absorb carbon dioxide in the air to form calcium carbonate and adhere to the inner wall of the pipe

Moreover, calcium carbonate is relatively hard and will form a large solidified substance after accumulating for a long time, which also poses a certain hidden danger to the personal safety of the cleaning personnel.

[0006] Therefore, it is very important to develop a high-efficiency and energy-saving method to solve the problems that the flue gas particles of the mixer cannot be directly discharged, the humidity of the flue gas is high, the white plume is serious, and the flue gas pipeline is easy to be blocked. Blocking and mist eliminator The method of dust removal and water collection can effectively eliminate the problem of blockage of the flue of the mixer, the problem of white smoke plume emitted by the flue gas of the mixer and the problem that the discharge of the mixer is not up to standard
