At present on ferroalloy smelting stove, mostly adopt malleation deashing dust-collecting equipment of reverse absorption, if dust arrester structure or filter bag design improper, usually occur that dust arrester runs unstable, faults frequent, many defects such as the construction life-span is short.
Utility model content
The technical problem to be solved in the present invention is to provide that a kind of structure is simple, the suction type action of low-voltage pulse bag-type dust collector of good dedusting effect, long service life.
For solving the problems of the technologies described above, the technical solution of the utility model is:
Process a suction type action of low-voltage pulse bag-type dust collector for boiler smoke, comprise air inlet duct, exhaust passage, Gas-cleaning box, dust filtering system, pulse jetting deashing system, store up grey ash discharging system and deflector, deflector is positioned at above air inlet duct; Dust filtering system is by the card of filter bag, installation filter bag and the bag cage of support filter bag and form; Gas-cleaning box is positioned at above filter bag; Store up grey ash discharging system to be made up of ash bucket and unloading valve, be positioned at below filter bag; Pulse jetting deashing system is made up of electromagnetic impulse valve, gas bag, air cylinder lifting valve, injection tube and winding-up mouth, and mouth of wherein jetting aims at filter pocket mouths downwards.
The spacing of described deflector and described card is greater than 500mm.
Described ash bucket is V-type, and base angle scope is 60 degree to 70 degree.
Described electromagnetic impulse valve is type submerged electromagnetic pulse valve, is directly installed on gas bag.
Described filter pocket mouths is provided with protective sleeve.
The utility model, by appropriate design, sets up deflector above air inlet duct, guides dusty gas to flow downward, then turns back upwards, dusty gas is fully contacted with filter bag under the effect of negative pressure, reaches desirable filter effect; The dust of filter bag can be removed easily by pulse jetting deashing system.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
A kind of suction type action of low-voltage pulse bag-type dust collector processing boiler smoke, as Figure 1-3, comprise air inlet duct 9, exhaust passage 7, Gas-cleaning box 1, dust filtering system, pulse jetting deashing system, store up grey ash discharging system, also comprise deflector 8, deflector 8 is positioned at above air inlet duct 9.Dust filtering system is made up of the bag cage of filter bag 12, the card 6 installing filter bag and support filter bag; Gas-cleaning box 1 is positioned at above filter bag 12; Store up grey ash discharging system to be made up of ash bucket 10 and unloading valve 11, be positioned at below filter bag 12; Pulse jetting deashing system is made up of electromagnetic impulse valve 4, gas bag 13, air cylinder lifting valve 5, injection tube 2 and winding-up mouth 3, and mouth 3 of wherein jetting aims at filter pocket mouths downwards.
Described deflector 8 is greater than 500mm with the spacing of described card 6, ensures equal wind, prevents local resistance too large, causes Gas-cleaning box 1 choke-out of keeping to the side, actual not situation in working order.
Described ash bucket 10 is V-type, and base angle scope is 60 degree to 70 degree.For the ash bucket 10 that surface is roomy, also should add inner support in ash bucket 10 inside, and add backing plate between inner support and ash bucket 10, avoid inner support to act directly on ash bucket 10, burst ash bucket 10 when high negative pressure; Inner support needs to do accumulatingdust process, and the general pipe that adopts does inner support.
Described electromagnetic impulse valve 4 is type submerged electromagnetic pulse valve, is directly installed on gas bag 13.Gas bag 13 can square air tank or circular gas bag, with reference to Fig. 2 and Fig. 3.
Gas bag 13 can be arranged on Gas-cleaning box top or Gas-cleaning box sidepiece, with reference to Fig. 4 and Fig. 5, and wherein preferred gas bag mounting means shown in Fig. 5.Because filter bag can not be installed in the space, bag room in the gas bag mounting means shown in Fig. 4 corresponding to gas bag bottom, waste a bag space, room; In gas bag mounting means shown in Fig. 5, gas bag has been contained in the outside of bag room, is fully used in space, bag room, and identical filter area steel consumption reduces, and the bent tube section of injection tube is exposed to air-purifying chamber outside, and construction and installation are more convenient.
Described filter pocket mouths is provided with protective sleeve, and protective sleeve can be built-in, also can be external, as shown in Figure 6.Protective metal shell is placed in filter pocket mouths by built-in sheath, have lost a part of filter area; External sheath, is placed in filter pocket mouths top by protective metal shell, ensure that the due filter area of filter bag.
Smoke filtration flow process of the present utility model: dusty gas is downward through air inlet duct 9 water conservancy diversion, then turns back upwards, enters into filter bag 12 inside by filter bag is outside through filter bag 12, and upwards flows out filter pocket mouths under the effect of negative pressure; In the process through filter bag 12, dust granules is retained by filter bag 12 filter course, and dusty gas is purified; Purified gas enters Gas-cleaning box 1 after flowing out filter pocket mouths, arrives exhaust passage 7, is entered in air by tail exhaust blower.
