Abstract
The invention relates to an exhaust gas purifier, in particular to a high temperature bag dedusting exhaust gas purifier. The high temperature bag dedusting exhaust gas purifier comprises a base seat, a bag chamber is arranged above the base seat, a clean air chamber is arranged above the bag chamber, an air outlet and an air inlet are formed in the side face of the bag chamber, an ash bucket is arranged inside the base seat, the air outlet is communicated with the clean air chamber, and the air inlet is communicated with the ash bucket. The bag chamber is provided with a plurality of filter bags, the bottom portions of the filter bags are arranged above the ash bucket, a spiral conveyer is arranged on the bottom portion of the ash bucket, and the spiral conveyer is provided with a rotating discharger. The mouth portions of the filters are communicated with the clean air chamber, the mouth portion of each filter bag is communicated with a blowpipe through a communication pipe, and the blowpipe is connected with an air storage tank through a pulse valve. Lime and active carbon granules are arranged outside the filter bags. The high temperature bag dedusting exhaust gas purifier is simple and compact in structure, and not only can remove big granules in dust ahead of time, but also cannot lower the flow speed of air flow. Each filter bag can achieve independent ash removal, and cannot affect the normal work of other parts.
Description
Technical field
The present invention is a kind of catalytic converter, particularly a kind ofly is applicable to collect the flue gas aluminium powder, purifies the high temperature bag dust-removing waste gas clarifier of the blowing purification combination of the inorganic waste gases that aluminium metallurgy industry and various industry produce.
Background technology
Traditional catalytic converter is off-line ash-clearing, adopts compressed air blowback cloth bag, and the dust that cloth bag is outer blows off as far as possible, and its dedusting effect is not good enough, and use is inconvenient, and in waste gas, the inorganic pollution emission level can't purify, and does not reach environmental requirement.
Summary of the invention
The objective of the invention is to invent a kind of high temperature bag dust-removing waste gas clarifier that adopts online ash removal to use simultaneously compressed air blowback cloth bag in order to overcome the not good enough defective of using inconvenience of existing catalytic converter efficiency of dust collection.
The objective of the invention is to realize as follows: described high temperature bag dust-removing waste gas clarifier, comprise base, the base top is provided with a bag chamber, top, bag chamber is provided with air-purifying chamber, the side of bag chamber is provided with gas outlet and air inlet, be provided with ash bucket in base, the gas outlet is communicated with air-purifying chamber, and air inlet is communicated with ash bucket; Bag is indoor is provided with a plurality of filter bags, and the bottom of filter bag is positioned at the top of ash bucket, and the bottom of ash bucket is provided with conveying worm, and conveying worm is provided with the revolution discharger; The oral area of filter bag is communicated with air-purifying chamber, and by being communicated with injection tube a communicating pipe, injection tube is connected with air accumulator by pulse valve the oral area of each filter bag separately.
The top of described air-purifying chamber is provided with changes a bag access door.
Pressure gauge and blowoff valve are housed on described air accumulator.
The outside of described filter bag is provided with lime and activated carbon granule.
Described filter bag adopts terylene needled felt, Chopped Strand Mat or heat resisting film-coating filtrate to make.
Good effect of the present invention is as follows: the present invention is simple and compact for structure, and it can either remove particle larger in dust and fine particle in advance, can not reduce again the flow velocity of air-flow; Each filter bag can realize that independent pressure reduction ash is clear, and namely keeping cloth bag pressure is 1700Pa, and the cloth bag Pressure Drop gets off and quits work again when impulse electromagnetic valve is started working, and can not affect the normal operation of other parts; Can also thoroughly purify the inorganic waste gases that aluminium metallurgy industry and various industry produce, automaticity is high, and good dedusting effect operates very easy to use.

The specific embodiment
As shown in Figure 1, described high temperature bag dust-removing waste gas clarifier comprises base 1, base 1 top is provided with bag chamber 2, and bag 2 tops, chamber are provided with air-purifying chamber 3, and the side of bag chamber 2 is provided with gas outlet 4 and air inlet 5, be provided with ash bucket 6 in base 1, gas outlet 4 is communicated with air-purifying chamber 3, and air inlet 5 is communicated with ash bucket 6; Bag is provided with a plurality of filter bags 7 in chamber 2, and the bottom of filter bag 7 is positioned at the top of ash bucket 6, and the bottom of ash bucket 6 is provided with conveying worm 8, and conveying worm 8 is provided with revolution discharger 9; The oral area of filter bag 7 is communicated with air-purifying chamber 3, and by being communicated with injection tube 11 communicating pipe 10, injection tube 11 is connected with air accumulator 13 by pulse valve 12 oral area of each filter bag 7 separately.
The top of described air-purifying chamber 3 is provided with changes bag access door 14.Can change bag by access door repair apparatus and locellus in normal operation, not affect the cleaner normal operation.
On described air accumulator 13, Pressure gauge and blowoff valve are housed.Can get rid of ponding and dirt in air accumulator by blowoff valve.
The outside of described filter bag 6 is provided with lime and activated carbon granule.Lime and activated carbon granule are favourable for the inorganic wastes of removing in waste gas.
Described filter bag 6 adopts terylene needled felt to make.Terylene needled felt, Chopped Strand Mat or heat resisting film-coating filtrate are made.These materials allow filtration velocity high, and resistance is low, easy-to-clean ash, and the life-span is long.
Operation principle of the present invention is as follows: dusty gas enters a bag chamber from air inlet by ash bucket, crude particle dust in air-flow directly falls into ash bucket, play the effect of gathering dust in advance, then air-flow upwards passes through filter bag, make dust be trapped in the outer surface of filter bag, purified gas enters air-purifying chamber by filter bag, then discharges from the gas outlet.During to certain thickness, the pulse valve action makes compressed air stream enter injection tube when the dust accumulation of filter bag outside, and sprays into communicating pipe in each filter bag by one group, makes the dust releasing that is captured on the filter bag outer wall.The dust settling that comes off is drained into technique through screw reamer and revolution discharger in the ash bucket and returns in grey conveying equipment.
