Abstract
The utility model relates to a channel type turbo fan dust remover, which is suitable for the dust removal of industrial metallurgical electric furnaces and coal-burning boilers. The utility model is provided with a main body of a channel type dust remover; a turbo fan which is driven by a motor is arranged in the main body; a water spraying device is arranged around the turbo fan; two groups of wire meshes are arranged in front of the turbo fan; each group of the wire meshes is composed of multiple-layer wire meshes; the back face of each layer of one group of the wire meshes near the turbo fan is provided with the water spraying device. The utility model utilizes the high-speed turbo fan to pressurize and accelerate the dusty gas in the channel, and simultaneously, utilizes a fan blade to beat the water for atomization. The action of the surface tension of the water is utilized for causing the water to form water membranes at the surfaces of the wire meshes. Thereby, the utility model has the advantages of simple structure, convenient operation, reliable operation and good dust-removing effect. The utility model not only has no pressure loss, but also has large positive pressure.
Description
The utility model relates to a kind of cleaner, is applicable to the dedusting of metallurgical electric furnace, coal-burning boiler, belongs to environmental protection dedusting field.
The industry metallurgy electric furnace produces a large amount of high temperature fine solid particle and pernicious gas, severe contamination work workshop and atmospheric environment in smelting process.The representative cleaner that uses has fiber bag precipitator, electric cleaner, civilian formula hydrofilter etc. at present.They respectively have the characteristics of oneself, but their some defectives have seriously influenced applying of they.
Fiber bag precipitator is used wider, and the subject matter that exists in actual motion is:
(1) material of cloth bag mostly is industrial polyester flannel greatly, and burning-point is lower, requires deduster and high temperature dirt source that certain distance is arranged, and high temperature dust gas is lowered the temperature in passage, or establishes wild air-valve and sneak into the temperature that cold air reduces dusty gas.Thereby dusty gas pressure loss in passage is increased, increased the power loss of whole system.
(2) the easy moisture absorption of fine solid particle that sticks on the cloth bag is tied plate, and the gas permeability of cloth bag is descended, thereby the pressure loss of deduster is increased.
(3) in order to strengthen the processing air quantity of deduster, must increase the filter area of cloth bag, the volume of equipment is increased, take the expensive place of a large amount of guarantors, increase the investment of equipment, strengthen maintenance difficulty.
So fiber bag precipitator is after operation a period of time, dust removing effects greatly descends, and can't normally move
Electric cleaner has adaptability preferably to the high temperature of dusty gas.But deduster is in running, when the battery lead plate laying dust reaches certain thickness, easily produce spark discharge, dust removing effects is greatly descended, if the air inlet end at deduster sprays into water smoke or water vapour, increase the conductance of dusty gas, reduce spark discharge, on battery lead plate, deposit but dust is easier.Wash with water as battery lead plate, can produce the dust-laden water slurry, and make electric cleaner lose the advantage of dry method dust.And the investment of electric cleaner is big, operation, maintenance cost height.Thereby influenced the popularization and application of electric cleaner.
In hydrofilter, representative civilian formula deduster, its dedusting is imitated better, but that greatest problem is the pressure loss is excessive, causes the power of whole dust-removal system bigger, energy consumption increases.
The purpose of this utility model provides a kind of good dedusting effect, and adaptability is strong, and is simple in structure, easy to use, reliable, the deduster of no crushing.
The purpose of this utility model is achieved in that
Channel-type deduster main body is established the turbofan by driven by motor in main body, establish water injector around fan; Before turbofan, establish two groups of woven wires, form by the multiple layer metal silk screen for every group; Establish water injector at one group of each layer of woven wire group back side near turbofan.
Motor is installed in the main body, and motor peripheral hardware radome fairing is cooling water sandwich between motor and the radome fairing.
The turbofan beam barrel is established the water flowing interlayer, and the beam barrel skin is established a plurality of delivery ports.
The water of the water injector ejection around the turbofan, and, all smashed atomizing by the turbofan blade by the water that turbofan beam barrel interlayer throws away.After dusty gas enters deduster by the air inlet end,, fully mix with water smoke simultaneously by turbofan acceleration, supercharging.Water injector is sprayed on the water on each layer woven wire surface of first group of woven wire, because the surface tension effects of water, water forms moisture film on the woven wire surface, and dust-laden water smoke contacts with the multilayer moisture film, reaches the purpose that absorbs dust-laden water smoke.Moisture film is contacted with dust-laden water smoke on second group of woven wire once more by the water droplet that air-flow dispels back formation, further absorbs dust-laden water smoke.Purify back gas through further entering atmosphere after the dehydration, sewage enters plash after cycle of treatment is used.
Advantage of the present utility model is:
The channel-type main body has reduced occupied ground and space, and deduster has big malleation, and deduster is simple in structure, and is easy to use, reliable, applied widely, and good dedusting effect.
Concrete structure of the present utility model is provided by following examples.
Figure (one) is the cutaway view according to the channel-type turbofan deduster that the utility model proposes.
This channel-type turbofan deduster is established channel-type main body (1), in main body, establish the turbofan (2) that drives by motor (6), establish ring-like sparge pipe group (3) in the turbofan stage casing, form by 2-10 sparge pipe for every group, evenly spray water to turbofan (2) blade, water is smashed by the high speed blade and atomizes, water has also washed turbofan (2) simultaneously, in the preceding woven wire group (9) of establishing of turbofan (2), (10), every group of woven wire is made of the 2-10 layer, the wire mesh holes order is the 16-52 order, sparge pipe group (4) is evenly sprayed water to each layer back side of woven wire group (9), because will being full of the woven wire eyelet, the surface tension effects of water, water form moisture film.
Motor (6) is installed in the main body (1), the tapered radome fairing of motor (6) peripheral hardware (5), to reduce resistance to air-flow, establish cooling water sandwich between motor (6) and the radome fairing (5), can feed cooling water, turbofan (2) beam barrel is established interlayer (7), and the beam barrel skin is established a plurality of delivery ports (8), the water that enters beam barrel interlayer (7) is smashed atomizing because centrifugal action throws away the back from delivery port (8) by the sheet leaf, and water has also washed turbofan (2) simultaneously.Radome fairing (5) is a pyramid type.
Dusty gas enters deduster by air inlet (11) end, fully mix with the water smoke that is smashed atomizing by turbofan (2) blade in the time of by turbofan (2) supercharging, acceleration, be first order dedusting, dust-laden water smoke contacts with the surperficial moisture film of woven wire group (9), be second level dedusting, the surperficial moisture film of woven wire group (9) is dispelled back formation by air-flow water droplet upward fully contacts in woven wire group (10) with dust-laden water smoke, be third level dedusting, purify back gas and enter atmosphere after further dewatering, sewage enters that plash is treated to be recycled.
