Description
Technical field
The present invention relates to a kind of high temperature bag filters of boiler.
Background technique
Bag filter is at present using commonplace dust-extraction unit.Its working mechanism is: thick in dusty gas
It being fallen directly into ash bucket after grain and the collision of dust settling pocket inner wall, the fine grained in dusty gas is filtered 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.
Summary of the invention
The present invention provides a kind of high temperature bag filters of boiler.
To solve the above-mentioned problems, the technical scheme adopted by the invention is that such, a kind of boiler is removed with high temperature cloth bag
The inside of dirt device, including dedusting shell, outer case of dust remover is separated into two parts up and down by card, and top is air-purifying chamber, and lower part is
Dirt pocket is arranged exhanst gas outlet on the side wall of air-purifying chamber, smoke inlet is arranged on the side wall of dirt pocket, if being hung on 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,
It is connected at the top of cyclone cylinder with card, the bottom wall that cyclone cylinder top passes through dirt pocket stretches out outside dirt pocket, and the bottom wall with 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 that the fast cooling of boiler smoke, the dedusting shell are double-layer interlayer structure, it is provided in interlayer
Cooling media.
In order to realize the centralized collection processing of dust, flue-dust retainer, the whirlwind are provided with below the dedusting shell
The roof that the taper tapping channel of cylinder passes through flue-dust retainer protrudes into flue-dust retainer, and mutually fixes with the top of flue-dust retainer.Preferably, institute
The flue-dust retainer bottom setting ash exhauster stated.
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 in outside dedusting shell are equipped with above the filter cloth bag
Press is connected.
The utility model has the advantages that
1, when working, boiler smoke by multiple air inlet pipe that cyclone cylinder top is arranged by being entered in dirt pocket in gas inlet machine
In cyclone cylinder, due to air inlet pipe and the tangent connection in cyclone cylinder top, so that accumulating one spiral into the flue gas in cyclone cylinder
The air-flow of shape movement, under the action of gravity and centrifugal force, in flue gas most of particle be thrown to after cyclone cylinder inner wall slide by
The discharge of taper tapping channel, the flue gas by pre- dedusting rises automatically along cyclone cylinder center, after being filtered using filter cloth bag, into
Enter air-purifying chamber, is discharged.The configuration of the present invention is simple plays protective effect good dedusting effect simultaneously to cloth bag.
2, the filter cloth bag that cyclone cylinder is covered in the present invention is exposed in air independently of each other, the nature outside cyclone cylinder
Air can cool down the flue gas in cyclone cylinder, reduce the processing temperature of filter cloth bag 3, therefore, be used for high temperature dust gas
When the processing of body, reduces because of the damage caused by high temperature to filter cloth bag, effectively extend the service life of filter cloth bag, reduce filtering
The maintenance and replacement workload of cloth bag, reduce operation and maintenance cost.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, should
The examples are only for explaining the invention, is not intended to limit the scope of the present invention..
Referring to Fig. 1, a kind of boiler high temperature bag filter, including dedusting shell, the inside of outer case of dust remover is by card
Two parts up and down are separated into, top is air-purifying chamber 1, and lower part is dirt pocket 2, and exhanst gas outlet is arranged on the side wall of air-purifying chamber, described
Exhanst gas outlet be connected with suction ventilator, smoke inlet is set on the side wall of dirt pocket, several opening upwards are hung on card
Filter cloth bag 3, the filter cloth bag 3 are connected with upper air-purifying chamber 1, and injection tube 4, the blowing are equipped with above the filter cloth bag
It manages and is connected with the air compressor machine (not illustrated in Fig. 1) being arranged in outside dedusting shell, the filter cloth bag is covered with cyclone cylinder 5,
The filter cloth bag 4 is located at the center of cyclone cylinder 5, and cyclone cylinder top is cylinder, and lower part is that the taper of reduced diameter discharges
Channel, 5 top of cyclone cylinder are connected with card, and the bottom wall that 5 lower end of cyclone cylinder passes through dirt pocket stretches out outside dirt pocket, and and dirt pocket
