Abstract
The invention relates to an air box pulse bag deduster. The deduster is formed by parallelly connecting a left box, a middle box and a right box, wherein the top of the box is provided with an upper cover plate; an air outlet is formed on the upper cover plate; the side part of the box is provided with an air buffer tank. The air buffer tank is connected with an air blowpipe via a pulse electromagnetic valve; and the air blowpipe is arranged on the upper part of the box, the interior of the box is provided with a filter bag, the upper part of the filter bag is connected with the box via a filter bag card, the lower part of the box is connected with a dust hopper, the upper part of the dust hopper is provided with an air inlet, and bottom of the dust hopper is provided with a dust discharge opening. Compared with the prior art, the air box pulse bag deduster overcomes shortcomings of conventional pulse dedusters and section reverse dedusters, and achieves the aim of completely removing dust by blowing once. The air box pulse bag deduster has advantages of strong chemical resistance, high filter efficiency, low discharge, large processing air flow, low pressure drop and long service life.
Description
Technical field
The present invention relates to a kind of cleaner, especially relate to a kind of air box impulse bag-type dust remover.
Background technology
The exhausted major part of existing deduster is many all to be to make of carbon steel material, this can't be suitable in the anti-strong acid of ask for something, anti-highly basic, field such as high temperature resistant at all, many times some producer have to adopt rare metal (as TA2) material to make to satisfy instructions for use, but expense is very high like this, causes the increase of production cost.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of anti-strong acid, anti-highly basic, high temperature resistant in order to overcome the defective that above-mentioned prior art exists, and filter efficiency height, discharging are low, the air box impulse bag-type dust remover that the flow of process air amount is big.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of air box impulse bag-type dust remover, it is characterized in that, this deduster is by left box body, middle casing and three parallel connecting to form of casing of right case, described casing top is provided with upper cover plate, this upper cover plate is provided with the gas outlet, the sidepiece of casing is provided with the air cushioning jar, this air cushioning jar is connected with gas blow pipe through the pulse magnetic valve, this gas blow pipe is located at the top of casing, the inside of casing is provided with filter bag, and filter bag top is connected with casing through the filter bag card, and the bottom of casing connects ash bucket, the top of ash bucket is provided with air inlet, and the bottom of ash bucket is provided with ash discharging hole.
Described filter bag adopts polytetrafluoroethylene (PTFE) or ceramic material to make.
Described ash bucket is a funnel shaped.
Compared with prior art, the present invention has the following advantages:
(1) this deduster adopts locellus blowing-out pulse jetting deashing technology, has overcome the shortcoming of conventional pulse dust collector and chamber-dividing counter-blowing deduster, and the deashing ability is strong, the efficiency of dust collection height, concentration of emission is low, and air leak rate of air curtain is little, less energy consumption, and the steel consumption is few, floor space is few, and stable and reliable operation is good in economic efficiency.Be applicable to the purification of dusty gas of metallurgy, building materials, cement, machinery, chemical industry, pharmacy, electric power, light industry and the recovery of material;
(2) owing to adopt locellus blowing-out pulse jetting deashing, winding-up once just can reach the purpose of thorough deashing, so cleaning cycle prolongs, has reduced the deashing energy consumption, and the consumption of calming the anger can greatly reduce.Simultaneously, the also corresponding attenuating of the degree of fatigue of filter bag and pulse valve, thereby the life-span of improving filter bag and valve block exponentially;
(3) after the polytetrafluoroethylene (PTFE) spraying is carried out on casing contact gas surface, but resistance to chemical corrosion is strong, can bear the acid and alkali corrosion of pH value from 0～14, temperature resistant range can be from-200 ℃～260 ℃, instantaneous temperature can arrive 315 ℃, and surperficial hydrophobic, anti-stick, uvioresistant;
(4) filter bag employing polytetrafluoroethylene (PTFE) or ceramic membrane are that material is made, but resistance to chemical corrosion is strong, can bear the acid and alkali corrosion of pH value from 0～14, temperature resistant range can be from-200 ℃～260 ℃, and instantaneous temperature can arrive 315 ℃, and surperficial hydrophobic, anti-stick, uvioresistant, not aging, the filter efficiency height/discharging is low, and the flow of process air amount is big/and pressure drop is low, uses the length of receiving a mandate.

Embodiment
A kind of air box impulse bag-type dust remover, its front view as shown in Figure 1, left view as shown in Figure 2, vertical view as shown in Figure 3, this deduster is by left box body 1, middle casing 2 and 3 three parallel connecting to form of casing of right case, the top of each casing is provided with upper cover plate 4, this upper cover plate 4 is provided with gas outlet 5, the sidepiece of casing is provided with air cushioning jar 6, this air cushioning jar 6 is connected with gas blow pipe 8 through pulse magnetic valve 7, and this gas blow pipe 8 is located at the top of casing, and the inside of casing is provided with filter bag 9, the top of filter bag 9 is connected with casing through filter bag card 10, filter bag 9 adopts polytetrafluoroethylene (PTFE) or ceramic material to make, and the bottom of casing connects ash bucket 11, and this ash bucket 11 is a funnel shaped, the top of ash bucket 11 is provided with air inlet 12, and the bottom of ash bucket 11 is provided with ash discharging hole 13.
During work, dusty gas enters ash bucket 11 by air inlet 12, thick grit directly falls into the bottom of ash bucket 11, discharge through ash discharging hole 12, dustshot upwards enters casing with the air-flow turnover, the long-pending outer surface that is attached to filter bag 9 of dust, the gas after the filtration enters the box cover gas outlet to pure qi (oxygen) concetrated pipe-exhausting duct, drains into atmosphere through exhaust blower.Deashing process is the gas outlet 5 that cuts off this chamber earlier, makes the filter bag 9 of this chamber be in the state (locellus blowing-out deashing) that airless passes through.Unbalanced pulse magnetic valve 7 usefulness compressed air carry out pulse jetting deashing then, the dust settling that the stop valve shut-in time is enough to guarantee after winding-up to peel off from filter bag 9 is to ash bucket 11, avoided dust behind the surface that breaks away from filter bag 9 again with the attached phenomenon that collects adjacent filter bag surface of air-flow, make filter bag 9 deashings thorough, and air bleeding valve, pulse valve and unloading valve etc. are carried out Automatic Control by the programmable controller.
