Abstract

The utility model discloses a dust catcher which comprises an electric precipitator and a bag deduster. An air outlet of the electric precipitator is communicated with an air inlet of the bag deduster; a shell body of the electric precipitator and a shell body of the bag deduster, which are combined, and the communication part of the air outlet of the electric precipitator and the air inlet of the bag deduster are combined to form a comprehensive transition part of the electric precipitator and the bag deduster. The composite electric bag dust catcher can maximize the comprehensive dedusting function of the dust catching function and the electric precipitator and the dust filtering and collecting function of the bag deduster when the temperature, the humidity and other natures of the smoke volume change in the working condition of a production enterprise, so as to achieve the dedusting effect which can not be achieved by a single electric precipitator or a bag deduster. Therefore, the dust catcher of the utility model has wider application occasions and range and unique high-low pressure automatic control system, and can realize patrol inspection, middle control and centralized control.

Description

A kind of deduster

Technical field

The utility model relates to a kind of deduster.

Background technology

The big-and-middle-sized environmental protection equipment that current manufacturing enterprise uses is mainly single electricity of structure or bag dust collector, but when manufacturing enterprise's operating mode flue gas fluctuation technological parameter is unstable, single electricity or its dust removing effects of bag dust collector are difficult to reach the requirement of the dust concentration discharge standard of national regulation on the performance, issuing and implementation along with new national environmental standard, enterprise's Air Pollutant Emission is had higher requirement, many for this reason enterprises begin to adopt low-sulfur coal or desulfurization measure, the wall resistance of dust changes in this emission that makes, exceeded the optimum scope of single electric cleaner, cause the dust collection efficiency of electric cleaner to reduce greatly, in recent years, bag dust collector is at filtrate, ash-clearing technology, technology such as automatic control have had very big progress, belong to high-effective dust-removing equipment, but the big particle in the exhaust gas dust has very galling to the filter bag of bag dust collector, reduce the service life of filter bag, because Dust Capacity is big, the cloth bag running resistance also improves, use the weak point of unicity deduster apparent, so its use occasion of electricity or bag dust collector and range of application all have certain limitation.

Summary of the invention

Technical problem to be solved in the utility model just provides a kind of deduster, and electric cleaner and bag dust collector combination are become one, and brings into play the combined dust-eliminating effect that electric cleaner captures the filtration collection dust of dust and bag dedusting to greatest extent.

In order to address the above problem, the utility model adopts following technical scheme: a kind of deduster, comprise electric cleaner and bag dust collector, and the electric precipitation air outlet is communicated with bag dedusting air inlet.

Electric cleaner housing and bag dust collector housing engage and are combined to form the comprehensive part of electricity bag transition with electric precipitation air outlet and the bag dedusting air inlet place of connection.

As preferably, the electric cleaner porch is provided with the airflow-distribution board of percent opening 〉=50% successively and has the deflector of flue gas guide effect.

As preferably, be linked with spoiler in the bag dust collector vertically downward, the top is provided with pulse valve and nozzle.

The utility model adopts the beneficial effect after the technique scheme: when manufacturing enterprise's operating mode exhaust gas volumn temperature, humidity and other smoke property change, can bring into play the combined dust-eliminating effect that electric cleaner captures the filtration collection dust of dust and bag dedusting to greatest extent, play the inaccessiable dust removing effects of single electricity or bag dust collector, be suitable for high resistivity dust collection, efficiency of dust collection has high efficiency and stability; Its use occasion and range of application are more extensive, have unique high-low pressure automatic control system, can realize patrolling and examining and centralized Control.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model electric cleaner and bag dust collector combining structure schematic diagram;

Fig. 2 is the vertical view of Fig. 1.

The specific embodiment

Deduster as shown in Figure 1 comprises electric cleaner 1 and bag dust collector 2, electric precipitation air outlet 6 is communicated with bag dedusting air inlet 7, and electric cleaner 1 housing and bag dust collector 2 housings engage and are combined to form the comprehensive part 3 of electricity bag transition with electric precipitation air outlet 6 and bag dedusting air inlet 7 places of connection.Ash-laden gas enters electric cleaner from electric precipitation air inlet 5, the first deflector 12 that passes through the airflow-distribution board 11 of percent opening 〉=50% and have the flue gas guide effect, in electric cleaner 1, be provided with relative positive plate 13 and minus plate 14, two battery lead plates are applied high voltage direct current, produce high voltage electric field between pole plate, when applying voltage when enough high, produce corona discharges near the minus plate 13, form a large amount of electronics, anion and cation.When ash-laden gas passes through electric field, dust adion or electronics are and charged, and charged dust is under the effect of electric field force, and the anisotropy electrode moves, the dust that arrives positive plate and discharges electric charge to pole plate in the effect deposit of electric field force and dust adhesion power in the above; And the dust of positively charged also is deposited on the minus plate 13 simultaneously, and dust granules is separated.When the two-plate dust reaches certain thickness, mode by rapping, dust releasing is entered in the electric precipitation ash bucket 15 below the electric field, the ash-laden gas that separated enters bag dust collector 2 by the comprehensive part 3 of electricity bag transition, bag dust collector 2 inside are divided into three parts by card 22 and central dividing plate 23, above the card 22 is air-purifying chamber 29, it between card 22 and the central dividing plate 23 middle casing 28, below the central dividing plate 23 is lower box 27, be connected with ash bucket 4 below the lower box 27, ash-laden gas at first enters lower box 27, oarse-grained slightly dust is subjected to stopping of central dividing plate 23, directly fall into following ash bucket 4, the flue gas that contains micronic dust directly enters air-purifying chamber 29 by updraft through central dividing plate 23, be linked with spoiler 24 in the air-purifying chamber 29 vertically downward, reduced the resistance of bag dust collector, make air current composition reasonable, flue gas enters filter bag 21 by spoiler 24, adsorbable all kinds of dust on the filter bag 21, flue gas after the dedusting is discharged through bag dedusting air outlet 8, as shown in Figure 2, the air-purifying chamber top is provided with pulse valve 25 and nozzle 26, when filter bag 21 surface dusts reach certain thickness, control system is sent the deashing instruction, compressed air makes filter bag 21 produce the pulse vibrations by pulse valve 25 and nozzle 26, and the dust shake on the filter bag 21 falls into ash bucket 4.

In addition to the implementation, the utility model also has other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the present utility model.
