Description
The utility model relates to wet type triple effect deduster, is applicable to mine, metallurgy, chemical industry, papermaking. and the dedusting of the non-hydrophobicity dusty gas of industries such as cement is specially adapted to brilliant, high humidity, viscosity is big, initial dustiness degree height, the occasion that dust granules is thin.
Wet scrubber is that water washs dust laden air and reaches the dedusting purpose.Press mode of washing, wet scrubber has the moisture film cyclone dust collectors, auto-excitation type cleaning type, venturi scrubber.The moisture film cyclone dust collectors are to add water spray on the sidewall of cyclone dust collectors, again discrete, horizontal two kinds.Vertical is widely used, and under dust granularity d 〉=20 μ m conditions, it has higher efficiency of dust collection, but when d＜20 μ m, particularly d＜10 μ m, efficiency of dust collection declines to a great extent.Use fewer in the dedusting in boiler, mine at present.Self-induced scrubber in indoor design " S " type curved, when dust-collecting air is curved by the S type, swashs the formula spray air fully contacted with water, thereby reach the dedusting purpose.It is applicable to the dust pelletizing system of dust granularity d 〉=10 μ m.Venturi scrubber utilizes the principle of Venturi throat, and violent the mixing collides when making water and air pass through Venturi tube in high speed, thereby reaches the purpose of dedusting.According to the difference of water and air, divide basic, normal, high pressure three kinds of forms again at aditus laryngis speed and drag losses.The dedusting that is applied to the mine is the low pressure venturi scrubber, drag losses is below 1500Pa, but dust pelletizing system for large-scale mine, the low pressure venturi scrubber has great weakness, because the air inlet after cleaner maximizes can't uniform air intake, it is low to cause aditus laryngis speed to have height to have, thereby efficiency of dust collection significantly reduces, the dewatering efficiency of deduster also declines to a great extent simultaneously, cause the fan belt water after the dedusting, the performance of blower fan is descended, cause that systematic air flow reduces, and causes vicious circle.In. the application of high pressure venturi scrubber all is limited to the occasion of special dedusting, as the converter gas recovery system of steel mill, plumbous flue gas during smelting cleaning system.
The purpose of this utility model is in order to improve above-mentioned several deduster, to propose the forceful action with draught fan impeller, allow water and dust laden air mix strong collision in blower fan, greatly improving the wet type triple effect deduster of efficiency of dust collection.
To achieve these goals, the utility model by the following technical solutions.
