At present the coal-burning boiler environmental emission reduction use gallet water curtain dust collector more generally.The gallet water curtain dust collector import that has also adds above mound star, in order to improve the desulfurization and dedusting effect, the star aditus laryngis position, civilian mound that has also adds shower water, the repacking eddy flow plate in granite duster that also has, the former dust removing effects is all right, desulfurized effect is poor, and latter's dust removing effects is bad, and desulfurized effect is also undesirable.Also often stop up on the eddy flow plate because of being stained with ash, bigger to boiler stability and safety influence on system operation.The dust-remover water consumption is big, and dust-containing water needs very big sedimentation basin, and heavy need of the ash that precipitates taken out with the driving grab bucket, and floor space is big, investment and operating cost height.Therefore, large-sized boiler is now many with electric precipitation or cloth bag dry method dust, semidry method or wet type desulfurizing are then adopted in desulfurization, total unavoidable three elutriations of dust secondary of dry method dust, contaminated environment, electric cleaner need increase power consumption, cloth bag dry method dust resistance has increased the air-introduced machine power consumption greatly equally, cloth bag is also bad easily, and maintenance load is big, and the investment cost of these two kinds of dust collection methods and operating cost are all quite high, large-sized boiler is used desulfurizer device structure complexity at present, investment cost is bigger, and operating cost is higher, and therefore a lot of medium and small boilers also do not have desulfurization.
The utility model content
The purpose of this utility model is to provide a kind of efficiency of dust collection height, the dust-removing desulfurating apparatus that resistance is little.
For achieving the above object, the utility model provides a kind of dust-removing desulfurating apparatus, it comprises cyclone separator, is arranged on the precipitation pond of cyclone separator bottom, be arranged on the airduct on cyclone separator top and be arranged on airduct interior Venturi tube and water inlet pipe, it is characterized in that: be provided with in the described airduct more than two and in parallelly be the Venturi tube of one, the throat of each Venturi tube is equipped with the sparge pipe that is connected with water inlet pipe.
The beneficial effects of the utility model are the fine deficiency that remedies above deduster of dust-removing desulfurizing device energy, it has dedusting, the two high integrated effects of desulfuration efficiency, simultaneously simple in structure, floor space is little, and expenditure of construction is low, and operating cost is low, there is not secondary pollution, durable in use, characteristics such as resistance is low, be little, in, the desirable environmental protection equipment of large coal-fired boiler.
Purification efficiency of the present utility model is improved, and has reduced drag losses, only is 2/3 of existing boiler smoke hydrofilter.At resistance with render a service under the constant situation, the minor diameter Venturi tube is many more in the airduct, and the air quantity of handling dust laden air is big more.When the gas flow of processed dust-laden sulfur-bearing was big, its efficiency of dust collection and resistance were constant substantially.
Description of drawings
Fig. 1 is the structural framing schematic diagram that meets a kind of dust-removing desulfurating apparatus of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing 1.But content of the present utility model is not only limited to so.
A kind of dust-removing desulfurating apparatus 1, it comprises cyclone separator 11, is arranged on the precipitation pond 12 of cyclone separator 11 bottoms, is arranged on the airduct 13 on cyclone separator 11 tops and is arranged on Venturi tube 14 and water inlet pipe 15 in the airduct 13.Be provided with in the described airduct 13 more than two and in parallelly be the Venturi tube 14 of one, the throat of each Venturi tube 14 is equipped with the sparge pipe 16 that is connected with water inlet pipe 15.
The beneficial effects of the utility model are the fine deficiency that remedies above deduster of dust-removing desulfurizing device energy, it has dedusting, the two high integrated effects of desulfuration efficiency, simultaneously simple in structure, floor space is little, and expenditure of construction is low, and operating cost is low, there is not secondary pollution, durable in use, characteristics such as resistance is low, be little, in, the desirable environmental protection equipment of large coal-fired boiler.
Purification efficiency of the present utility model is improved, and has reduced drag losses, only is 2/3 of existing boiler smoke hydrofilter.At resistance with render a service under the constant situation, the minor diameter Venturi tube is many more in the airduct, and the air quantity of handling dust laden air is big more.When the gas flow of processed dust-laden sulfur-bearing was big, its efficiency of dust collection and resistance were constant substantially.
