Abstract
The utility model relates to an induced draft type dust removal and desulfurization device for separating dispersed particles in flue gas and removing harmful gases such as sulfur dioxide. The smoke dust separation device comprises a shell, a smoke dust separation part and a water pool, wherein the smoke dust separation part and the water pool are arranged in the shell, the smoke dust separation part is a rotary impeller which plays a role in inducing air and separating smoke dust, an air inlet communicated with an impeller inlet is formed in the shell on the front side of the impeller, a baffle plate with holes is arranged on the rear side of the impeller, and the water pool is arranged below the impeller. It features that it integrates air-inducing and dust-removing into one body, and utilizes the centrifugal force produced by high-speed rotation of blade wheel to separate flue gas from dust, at the same time can send out flue gas, and its structure is simple, cost is low and dust-removing and desulfurizing efficiency is high.
Description
The utility model relates to dispersed granules in a kind of minute separable flue gas and removes the induced air type dust-removing desulfurating apparatus of pernicious gas such as sulfur dioxide.
Existing deduster all is to be used with air-introduced machine, promptly make the flue gas cleaner of flowing through by the effect of air-introduced machine, by it grit in flue gas is separated, its deficiency is: because deduster self has certain resistance, therefore the blower fan power demand is bigger, and its operating cost is higher; Deduster cost height.
It is one that the purpose of this utility model is to provide a kind of collection air inducing, dedusting, has the induced air type dust-removing desulfurating apparatus of higher dust-removal and desulfurizing efficient.
The purpose of this utility model be achieved in that with have dust-removal and desulfurizing equipment identical be that it has housing, is arranged on flue dust separating component and pond in the housing, its special character is that the flue dust separating component is for playing air inducing and with the rotary blade of flue dust centrifugation, the housing that is positioned at the impeller front side is provided with the air inlet that links to each other and can lead to impeller inlet, the impeller rear side is provided with baffle plate with holes, and the below of impeller is provided with the pond.
Described baffle plate with holes is a spirality plate washer with holes, and flue gas is discharged from baffle holes after baffle plate forms swirling eddy, can further remove pernicious gases such as flue dust and sulfur dioxide.
The water surface in pond, impeller below and the distance of impeller end are 10～20cm.Can under the acting in conjunction of the impeller of at a high speed rotation and whereabouts flue dust, constantly hit spray like this and reacted, reach the purpose of desulfurization with sulfur in smoke.
The pond of impeller below is connected with settling tank, and the bottom surface in pond is the inclined-plane.The dust that adopts this structure can guarantee to enter in the pond directly falls into settling tank.
In housing, be tiltedly installed with the herringbone water fender by the place, gas outlet.
Characteristics of the present utility model are:
1, its collection air inducing and dedusting is an one, promptly utilizes centrifugal force that impeller rotates generation at a high speed in flue gas and dust separation, can send flue gas automatically again, and it is simple in structure, cost is low, the efficiency of dust collection height.
2, the extraneous resistance of induced air type dust-removing desulfurating apparatus is less, and impeller rotation power demand is little, saves electric energy, reduces operating cost.
3, utilize the centrifugal force of impeller generation and the dust of whereabouts constantly to hit spray, it is fully mixed with flue gas, can remove pernicious gases such as sulfur in smoke effectively, the desulfuration efficiency height.
4, the utility model floor space is little, and installation and maintenance are convenient, and are stable.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side diagrammatic sketch of Fig. 1.
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, 2, housing of the present utility model (1) is to be connected and composed by upper and lower two parts, so that maintenance.The housing employing is anticorrosion, high-abrasive material is made.Case top is provided with gas outlet (2), and a side is provided with air inlet (3), and lower openings is connected with pond (4), and promptly parallel with the impeller shaft housing sidewall in the one or both sides of its middle shell is goed deep in the pond, and all the other sidewalls then are tightly connected with the pond.The pond is connected with settling tank (5), and the bottom surface in pond is the inclined-plane.The settling tank top is provided with cover plate (6), and a side is provided with overflow pipe (7) and water inlet pipe (8).Two pipes the water surface elevation that can guarantee the pond is set.The spacing of the present embodiment pond water surface and impeller end is about 13cm.If water level rises, then discharge by overflow pipe.When water level descends, can be by water inlet pipe to the pond water filling.The impeller (9) that is made of blade and forward and backward cover plate adopts corrosion-proof wear-resistant material to make, and what of the size of impeller and blade should be determined according to supporting boiler.Impeller inlet is connected with shell air inlet contraction section (16).The baffle plate with holes (10) that is positioned at the impeller rear side is spiral baffle with holes, and it is fixed on the inner walls.Being provided with of baffle plate can make liquid, gas further fully mix and stop that the dust of throwing to shell wall taken away by flue gas stream again.Stretch out the outer impeller shaft (11) of housing and be arranged on the bearing block (12), its end is provided with by the belt pulley of driven by motor (13).Bearing block is fixed on the support (14).Be tiltedly installed with herringbone water fender (15) by the place, gas outlet in the housing.
During work, rotate by the driven by motor impeller shaft, impeller rotates thereupon, ash-laden gas enters in the impeller, under the action of centrifugal force of rotary blade, dust is thrown to shell wall and is fallen in the pond along it, and this moment is at the impeller of at a high speed rotation and fall into dust in the pond and hit a large amount of sprays under impacting in order to adsorb pernicious gas such as sulfur in smoke.Flue gas forms eddy flow during through spiral baffle with holes, and it will make liquid gas further mix collision, decompose to quicken chemical combination.The flue gas through after the dust-removal and desulfurizing processing of discharging from the spiral baffle hole is discharged from the housing gas outlet through water fender again.
