Abstract
The utility model belongs to the boiler fixture, which adopts the device combining a hollow helicoid heat exchanger and a centrifugal dust remover as integration. The structure of the coal-saving dust remover is composed of multi groups of hollow helicoids, and the cooling water passes in the hollow helicoids. The boiler flue gas enters the outer cavities of the helicoids along the tangential direction, the dust in the flue gas is divided into the dust storage tin at the lower part after rotated, and the flue gas is discharged from the exhaust port at the upper part. The cooling water reclaims and reuses the residual heat in the flue gas. The utility model has the advantages of small space volume, steel-saving, good effects of coal saving and dust removing, etc.
Description
The utility model belongs to boiler fixture.
Boiler all is two equipment that separate with economizer and deduster at present.Economizer takes up space greatly, and the consumption steel are many, and the cost height uses easy dewfall dust, stops up flue.Deduster generally adopts water film dedusting, bag-type dust or centrifugal dust-removing.Water film dedusting can cause the secondary pollution of water, is difficult for handling, and moisture film easily freezed again and should not use winter; The bag-type dust consumable accessory is many, the operating cost height; The centrifugal dust-removing effect is better.
The purpose of this utility model is to provide a kind of deduster of economizing on coal of economizing on coal and combining with two kinds of functions of dedusting.Adopt the method for empty stomach conveyor screw heat exchanger and centrifugal dust-removing, have the saving steel, spatial volume is little, the characteristics of the good dedusting effect of economizing on coal.
As shown in Figure 1, the utility model is to realize like this.4～5 groups of conveyor screws 2 are on an empty stomach arranged in spiral shell shell 1, insert a water inlet pipe 4, one outlet pipes 6 from spiral shell shell external vertical.Water inlet pipe directly with conveyor screw on an empty stomach in the rounded head bottom is in series, outlet pipe directly is in series with the top of the outer rounded head of conveyor screw on an empty stomach.On the tangential direction of spiral shell shell cylindrical, connect a gas approach 5, one exhaust opening 3 is arranged in center, spiral shell shell upper end.Connect a hollow cone body 7 in spiral shell shell bottom by flange.The hollow cone body can be made vertical.As shown in Figure 2, can also make ox horn shape curved formula.A fixing annular radiation shield 8 is arranged in the bottom of hollow cone body, the gap is between 20～30 millimeters between radiation shield cylindrical and the hollow cone body inwall, the annular internal diameter is 40～50 millimeters, bottom at the hollow cone body connects a dust collecting bucket 9 with flange, and Weight type dust discharge valve 10 is arranged at the dust collecting bucket bottom.
As shown in Figure 3, in order to adapt to the needs of large-tonnage boiler, two dedusters of economizing on coal can also parallel connection be a gas approach and a smoke evacuation outlet.The import and export size is amplified accordingly.
The deduster of economizing on coal that provides according to the utility model enters water and the external hot flue gas reverse flow that imports from gas approach in the conveyor screw by feed pump, and the temperature of water is improved constantly.Calculate with 20 tons of water/hour water supply, by behind this device, temperature can improve 4 ℃, and reclaiming heat is 75000 kilocalories/hour, and boiler thermal output improves 12%.Accomplish to make full use of the heat of flue hot gas, owing to reduced flue-gas temperature, can also prolong the life-span of air-introduced machine simultaneously.
Hot flue gas rotates after the conveyor screw tangential direction enters conveyor screw gradually, and soot dust granule is subjected to action of centrifugal force and descends along wall, enters in the dust collecting bucket.Because there is an annular reflection screen dust collecting bucket top, the interior ring of radiation shield central authorities can make and be formed centrally negative pressure whirlwind post in the bullet, therefrom by after spread, reduce or avoid the dust that falls into dust collecting bucket is discharged from exhaust opening again.Record dust removing effects 75～95% through test, particle size of dust accounts for more than 25% below 200 orders, reaches the purpose of purifying and dedusting.
Economizer and two kinds of equipment of centrifugal deduster are united two into one, significantly reduced spatial volume, save steel, reduce cost.
