Description
Technical field
The invention belongs to waste gas purification apparatus technical field, be specifically related to a kind of flue gas desulfurization and dedusting haze purification device, be applicable to produce the factories and miness of exhaust gas dust and the tobacco process of electric furnace steel making.
Background technology
Traditionally, for the dust in elimination furnace flue gas, conventional method is cell-type water film dedusting method, and this method is while the flue gas of being discharged by stove is introduced in dirt pocket, after the flue gas entered in dirt pocket being sprayed with the spray equipment that can form moisture film, then discharge.Adopt in this way, although also can remove the part fine grained dust in flue gas, because the dust in flue gas is soaked rear ability sedimentation by moisture film aloft, for not yet by the micronic dust soaked, still do not have filtering effect, dust removing effects is bad.In addition, this dust collection method needs huge dirt pocket and equipment, and not only floor space is large, and investment is also many.
The applicant once the applying date be on December 23rd, 1998, the patent No. is disclose a kind of deduster in the Chinese invention patent of 98247422.9, it comprises housing, there are base and dust fall bucket in the lower end of housing, its upper and lower end has respectively and draws mouth and enter mouth, it is characterized in that the shelf had in the middle of housing cavity for forming upper and lower chamber.Upper and lower chamber respectively with draw mouth and enter mouth and communicate, be stacked with some hollow adsorbents in epicoele, this hollow adsorbent have some through holes communicated with its inner chamber.Have spray equipment in epicoele, this spray equipment is on hollow adsorbent.This deduster can filter out the grade crude particle dust in flue gas, but can not meet today that the needs of environmental protection now, particularly haze have a strong impact on people's life, and this deduster is for SO
2and micronic dust is just helpless.
Summary of the invention
The invention provides a kind of flue gas desulfurization and dedusting haze purification device, adopt level Four purification, by the SO in flue gas
2and dust, and PM2.5 micronic dust is all removed totally, can meet the needs of environmental protection now, allows the life of people affect from haze, is specially adapted to produce the factories and miness of exhaust gas dust and the tobacco process of electric furnace steel making.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: flue gas desulfurization and dedusting haze purification device, comprise the first dedusting and desulfurization chamber be communicated with successively, second dedusting and desulfurization chamber, except haze room and smart filter chamber, described first dedusting and desulfurization chamber and the second dust-removal and desulfurizing indoor are respectively equipped with the first dividing plate and second partition, hollow adsorbing sphere is all stacked with above described first dividing plate and second partition, described first dedusting and desulfurization chamber and the second dust-removal and desulfurizing indoor, water ring is equipped with above described hollow adsorbing sphere, dust fall bucket is equipped with bottom described first dedusting and desulfurization chamber and the second dedusting and desulfurization chamber, neutralization pond is provided with below described dust fall bucket, alkaline solution is contained with in described neutralization pond, described removing below haze room is provided with storage pool, is contained with the emulsion for the manufacture of foam, is positioned at described emulsion liquid level place and is provided with blast orifice in described storage pool, and described haze indoor of removing are provided with the 3rd dividing plate, are provided with water filter above described 3rd dividing plate, be provided with the 4th dividing plate in described smart filter chamber, above described 4th dividing plate, be stacked with steel wire lump.
Be provided with below first dividing plate into mouth, the first dedusting and desulfurization chamber is communicated with the second dedusting and desulfurization chamber top, and the cavity below second partition is communicated with the cavity below the 3rd dividing plate, except haze room is communicated with smart filter chamber top, is provided with and draws mouth below the 4th dividing plate.
