Abstract
The utility model relates to an electrostatic desulfurized dust remover in front of a shaft well for desulfurizing, removing dust and purifying air, comprising an electrostatic dust remover. The utility model is characterized in that a shaft well for desulfurizing and removing dust is arranged in front of the electrostatic dust remover, and the side lower part of the shaft well is provided with a fume inlet; the middle upper part of the shaft well is provided with a Ca liquid spraying device, and a spray head of the device is communicated with a filter, a Ca liquid pump and a Ca liquid tank through pipelines. The utility model having the advantages of high desulfurizing and dust removing efficiencies, low running cost and proper price is ideal environmental protection equipment.
Description
The utility model relates to a kind of device of desulfurization dust separation air.
At present, the desulfurization and dedusting modification scheme of coal-burned industrial boiler mainly is to transform on the basis of former venturi water film deduster, the dust-removal and desulfurizing equipment that its representative scheme has Changsha Lu Nan environmental protection equipment factory, the global environmental protection equipment in Changsha factory to produce, its basic characteristics are that the cylindrical shell of former water dust scrubber is transformed, use has the function on chemical industry absorption tower, the major defect of this type of scheme is that efficiency of dust collection is lower than 98%, desulfurized effect is then lower, and the flue windage increases, outlet flue gas with water, desulfurization and dedusting partly wear and tear dirty stifled heavier.
The purpose of this utility model is to provide a kind of desulfurization dust-removing efficiency higher, and the low environmental protection equipment of operating cost.
The purpose of this utility model is achieved in that the utility model comprises electrostatic precipitator, before electrostatic precipitator, be provided with a desulfurization and dedusting vertical shaft, its structure is that the side lower part of vertical shaft is provided with gas approach, be provided with Ca liquid flusher on vertical shaft top, the shower nozzle of this device is connected with filter, Ca liquid pump, Ca liquid case by pipeline.
Be provided with mortar circulation flusher in the utility model vertical shaft, its structure is that the silo bottom outlet links to each other with mortar circulating pump shower nozzle by pipeline.
First utmost point of the utility model electrostatic precipitator is provided with positive plate dust water flushing device, and its structure is for to be equipped with water pipe on positive plate, and water pipe is provided with baffle plate.
Advantage of the present utility model is the dust-remover vertical shaft is combined with electrostatic precipitator, realize the desulfurization of flue gas, the dedusting dehumidifying, efficiency of dust collection is reached more than 99.5%, in the first order of electrostatic precipitator, remove simultaneously the anode rapping apparatus, the anode water flusher is set, thereby guaranteed the cleaning of positive plate, and utilize this deduster can remove moisture content in the air-flow, further remove water-soluble SO2 and SO3, reach the purpose of further raising desulfuration efficiency, in the utility model, be provided with grey water circulation system, to make full use of the desulfidation of alkaline matter contained in Ca (OH) 2 that add of spray and the buck, to realize reducing the purpose of operating cost.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model positive plate dust water flushing device side view.
Wherein 1 is electrostatic precipitator, and 2 is vertical shaft, and 3 is nozzle, and 4 is filter, and 5 is the Ca liquid pump, and 6 is Ca liquid case, and 7 is mortar pool, and 8 is the mortar circulating pump, and 9 is gas approach, and 10 is positive plate, and 11 is water pipe, and 12 is baffle plate.
Below in conjunction with accompanying drawing the utility model is done detailed description.
As shown in drawings, the utility model is made up of the two large divisions, and a preceding part is a desulfurization and dedusting vertical shaft 2, and desulfurization and dedusting vertical shaft 2 is connected with electrostatic precipitator 1, in vertical shaft 2, be provided with nozzle 3, and nozzle 3 is an atomizer, utilizes ceramic material, to improve its anti-wear performance and decay resistance, the quantity of nozzle 3 is many more, its desulfurization and dedusting effect is good more, and nozzle 3 and filter 4, Ca liquid pump 5 and Ca liquid case 6 communicate the Ca (OH) in the Ca liquid case 6 by pipeline
2Flow at the drive lower edge of Ca liquid pump 5 pipeline, filtration through filter 4, from nozzle 3 ejections, combine with flue gas and reach the purpose of desulfurization and dedusting, in vertical shaft 2, also be provided with mortar circulation flusher, primary structure is for being provided with mortar pool 7 in vertical shaft 2 bottoms, the outlet of mortar pool 7 links to each other with mortar circulating pump 8 by pipeline, alkaline matter in the available mortar is transported to nozzle 3 in the vertical shaft 2 once more by mortar circulating pump 8, the recirculation of realization mortar, the side lower part of vertical shaft 2 is provided with gas approach 9.First utmost point in electrostatic precipitator 1 is provided with positive plate dust water flushing device, as shown in Figure 2, its structure is provided with water pipe 11 for the top of this positive plate 10, is provided with baffle plate 12 for anti-sealing arbitrarily flashes on water pipe 11, positive plate is kept clean, to improve its efficiency of dust collection.
Claims (3)
