Description
Technical field
It the utility model is related to a kind of high temperature bag filter of boiler.
Background technology
Bag filter is to apply commonplace dust-extraction unit at present.Its working mechanism is：Thick in dusty gas
With being fallen directly into after the collision of dust settling pocket inner wall in ash bucket, the fine grained in dusty gas is filtered grain by dust settling pocket, from
And realize the dedusting of dusty gas.But existing bag filter, during above-mentioned dedusting, boiler smoke is largely inhaled
Be attached to the filtering function that dust settling pocket has been seriously affected on the filtering surface of dust settling pocket, thus need frequently to the dust on dust settling pocket into
Row cleaning.
Utility model content
The utility model provides a kind of high temperature bag filter of boiler.
To solve the above-mentioned problems, the technical solution adopted in the present invention is such that a kind of boiler is removed with high temperature cloth bag
Dirt device, including dedusting shell, the inside of outer case of dust remover are separated into two parts up and down by card, and top is air-purifying chamber, and lower part is
Dirt pocket, sets exhanst gas outlet on the side wall of air-purifying chamber, smoke inlet is set on the side wall of dirt pocket, if being hung with card
The filter cloth bag of dry opening upwards, the filter cloth bag are connected with upper air-purifying chamber, and the filter cloth bag is covered with cyclone cylinder, should
Filter cloth bag is located at the center of cyclone cylinder, and cyclone cylinder top is cylinder, and lower part is the taper tapping channel of reduced diameter,
Be connected with card at the top of cyclone cylinder, cyclone cylinder top through outside the bottom wall stretching dirt pocket of dirt pocket, and with the bottom wall of dirt pocket
Mutually fixed, cyclone cylinder top is provided with multiple air inlet pipe, the air inlet pipe and the tangent connection in cyclone cylinder top.
In order to realize the fast cooling of boiler smoke, the dedusting shell is double-layer interlayer structure, is provided with interlayer
Cooling media.
In order to realize that the centralized collection of dust is handled, flue-dust retainer, the whirlwind are provided with below the dedusting shell
The roof of the taper tapping channel of cylinder through flue-dust retainer is stretched into flue-dust retainer, and is mutually fixed with the top of flue-dust retainer.Preferably, institute
The flue-dust retainer bottom stated sets ash exhauster.
In order to accelerate efficiency of dust collection, the exhanst gas outlet is connected with suction ventilator.
Preferably, injection tube, the injection tube and the sky being arranged on outside dedusting shell are equipped with above the filter cloth bag
Press is connected.
Beneficial effect：
When the 1st, working, boiler smoke is by multiple air inlet pipe in dirt pocket in gas inlet machine, being set by cyclone cylinder top
Into in cyclone cylinder, due to air inlet pipe and the tangent connection in cyclone cylinder top so that accumulate one into the flue gas in cyclone cylinder
The air-flow of corkscrew motion, under the action of gravity and centrifugal force, most of particle is slided after being thrown to cyclone cylinder inner wall in flue gas
Fall and discharged by taper tapping channel, the flue gas by pre- dedusting rises automatically along cyclone cylinder center, then filtered Bag filter
Afterwards, into air-purifying chamber, discharge.The utility model is simple in structure, and protective effect good dedusting effect at the same time is played to cloth bag.
2nd, the filter cloth bag of cyclone cylinder is covered with the utility model, independently of each other, in air, outside cyclone cylinder
Natural air can cool down the flue gas in cyclone cylinder, reduce the processing temperature of filter cloth bag 3, therefore, contain for high temperature
During the processing of dust and gas body, the damage to filter cloth bag caused by high temperature is reduced, effectively extends the service life of filter cloth bag, is reduced
The maintenance of filter cloth bag and replacement workload, reduce operation and maintenance cost.
