Abstract
The utility model relates to a dust-removal device and especially relates to a boiler spray desulphurization and dust-removal device. The boiler spray desulphurization and dust-removal device belongs to the technical field of boiler dust-removal equipment. The boiler spray desulphurization and dust-removal device comprises a housing, a gas inlet, a spray generator, a water tank and a gas outlet. An upper part of the housing is provided with the gas inlet. One side of the housing is provided with the gas outlet and the other side of the housing is provided with a desulphurization opening and a dust-removal opening, wherein the desulphurization opening and the dust-removal opening are distributed from top to bottom. A baffle is arranged in the housing. The spray generator is arranged below the baffle. The boiler spray desulphurization and dust-removal device has a simple structure and good desulphurization and dust-removal effects. In working, under the action of the gas outlet, when flue gas with a desulphurization liquid moves to the joint of a top plate and a reflux plate, a large amount of foam is produced by reflux plate blocking so that dust and sulfur dioxide in the flue gas are dissolved in the foam and then are precipitated in the desulphurization liquid and thus desulphurization and dust-removal are realized. The boiler spray desulphurization and dust-removal device has dust-removal efficiency of 99% and desulphurization efficiency more than 90%.
Description
Technical field
The utility model relates to a kind of dust arrester, is specifically related to a kind of boiler foam desulfation dust-extraction device, belongs to the boiler dust removal equipment technical field.
Background technology
Coal-burning boiler is the main heating equipment of industrial production and domestic life aspect.Because coal-fired sulfur content is high, cause dust and sulfur dioxide gas contained in the flue gas that boiler emission goes out a lot, be to cause one of environment and air-polluting primary pollution source.Especially the moisture in the wet flue gas is discharged in a large number and forms fog in the atmosphere, very easily people's breathing is produced certain impact, even affects people's normal life.
For a long time, in the employed cleaner of desulfurization and dedusting in the boiler smoke, in the majority with the double-tower type water dust scrubber, desulfurization and dedusting mainly contains dry type and two kinds of ripe techniques of wet desulphurization, dry type desulfurizing technique is lime stone directly to be blown in the boiler furnace burn with fire coal, reach the purpose of desulfurization with the discharge that reduces sulfur dioxide, its shortcoming is to be applicable to large-sized boiler, and medium small boiler can't use.Wet desulphurization is to carry out circulated sprinkling with the water that contains alkaline matter, reaches the purpose of desulfurization and dedusting by steam-water mixing, because during the work of double-tower type water dust scrubber, constantly the water of spray makes operating cost very high, has indirectly increased the production cost of enterprise.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, operating cost is low, and desulfurization and dedusting is effective, and boiler foam desulfation dust-extraction device easy to install.
The technical solution of the utility model is:
A kind of boiler foam desulfation dust-extraction device, it is made of housing, air inlet, foam generator, pond and gas outlet, it is characterized in that: the top of housing is provided with air inlet, one side of housing is provided with the gas outlet, the opposite side of housing is up and down, and shape is provided with desulfurization mouth and dedusting mouth, enclosure interior is provided with baffle plate, and the baffle plate below is provided with the foam generator, and described foam generator below is provided with the pond.
Described foam generator is made of reaction plate, top board, back flow plate and shock plate, reaction plate, top board and back flow plate be "
∩" setting of word shape, the top board below vertical configuration between reaction plate and the back flow plate is provided with shock plate.
The utility model has the advantage of:
The foam generator of this boiler foam desulfation dust-extraction device is learned principle according to motive fluid and is developed, have simple in structure, the characteristics that desulfurization and dedusting is effective, in the course of work, the flue gas that is entered by air inlet forms one to the doctor solution in the pond and dives and be dissolved in the doctor solution, under the effect of gas outlet, the smoke movement that is being mingled with doctor solution is during to top board and back flow plate junction, the a large amount of foam of formation under the stopping of back flow plate, thereby make dust in the flue gas and sulfur dioxide be dissolved in the foam and be deposited in the doctor solution, reach thus the desulfurization and dedusting purpose.The water of effectively having avoided existing water dust scrubber constantly to spray makes operating cost very high, has indirectly increased the problem of enterprise's production cost.The efficiency of dust collection of this boiler foam desulfation dust-extraction device can reach 99%, and desulfuration efficiency can reach more than 90%.
Description of drawings
Fig. 1 is sectional structure schematic diagram of the present utility model.
Among the figure: 1, housing, 2, air inlet, 3, the pond, 4, the gas outlet, 5, the desulfurization mouth, 6, the dedusting mouth, 7, baffle plate, 8, doctor solution, 9, reaction plate, 10, top board, 11, back flow plate, 12, shock plate.
The specific embodiment
This boiler foam desulfation dust-extraction device is made of housing 1, air inlet 2, foam generator, pond 3 and gas outlet 4.The top of housing 1 is provided with air inlet 2, and a side of housing 1 is provided with gas outlet 4, and shape was provided with desulfurization mouth 5 and dedusting mouth 6 about the opposite side of housing 1 was.Desulfurization mouth 5 is used for the injection of desulfurizing agent, outside the discharge housing 1 of dedusting mouth 6 for the impurity such as dust that will precipitate.Housing 1 inner and upper is provided with baffle plate 7, and baffle plate 7 belows are provided with the foam generator, and the foam generator is made of reaction plate 9, top board 10, back flow plate 11 and shock plate 12, reaction plate 9, top board 10 and back flow plate 11 be "
∩" setting of word shape, the top board 10 below vertical configurations between reaction plate 9 and the back flow plate 11 are provided with shock plate 12.
Foam generator below is provided with pond 3, and pond 3 is loaded with doctor solution 8.
Foam generator of the present utility model is to learn principle and develop according to motive fluid, in the course of work, the desulphurizer mixing that the flue gas that is entered by air inlet 2 at first enters with the desulfurization mouth, simultaneously the doctor solution 8 in the pond 3 is formed one and impact and form aerosol, make part dust and sulfur dioxide in the flue gas be dissolved in the doctor solution 8 and precipitation, under the fan action of gas outlet 4, the smoke movement that is being mingled with doctor solution 8 is during to top board 10 and back flow plate 11 junction, the a large amount of foam (spray) of formation under the stopping of back flow plate 11, thereby make dust residual in the flue gas and sulfur dioxide again be dissolved in the foam and be deposited in the doctor solution 8, reach thus the desulfurization and dedusting purpose.The efficiency of dust collection of this boiler foam desulfation dust-extraction device can reach 99%, and desulfuration efficiency can reach more than 90%, have simple in structure, the characteristics that desulfurization and dedusting is effective.
