Description

Pulse blowing bag type dust precipitator with conduction type spray nozzle device

Technical field:

The present invention relates to a kind of pulse blowing bag type dust precipitator, particularly relate to a kind of pulse blowing bag type dust precipitator with conduction type spray nozzle device.

Background technology:

In order to safeguard the demand of production environment cleaning; and clear up at any time by the place of dirt ash fouling; capital set pulse blowing bag-type dust remover carries out cleaning; yet; pulse blowing bag type dust precipitator is in dust removal process; can be at leisure on the filter bag of pulse blowing bag type dust precipitator dirt ash layer by layer on the bonding; accumulate over a long period and promptly can reduce efficiency of dust collection; therefore; regular meeting carries out the dedusting cleaning according to different operating positions to the filter bag surface; so that recover good dust removing effects; the injection system of common employed pulse blowing bag type dust precipitator all is directly to blow to the filter bag inner surface by compressed air by the spout on the winding-up pipe to implement the dedusting of filter bag outer surface is cleared up; both ash-removal effect is poor like this; it is bad to cause filter bag to be blown easily again; and the complete machine work that also can give the afterpulse blowing bag-type dust remover brings certain influence, and causes that the dirt ash fouling to peripheral production environment does not reach timely or perfect processing.

Summary of the invention:

The objective of the invention is to provide a kind of pulse blowing bag type dust precipitator with conduction type spray nozzle device, it not only can effectively utilize pulse jet ash disposal cleaning filter bag, and, make filter bag be difficult for suffering damage.

In order to realize that above-mentioned purpose the present invention proposes following design: the pulse blowing bag type dust precipitator with conduction type spray nozzle device of the present invention has an ash bucket, the end, lower end of described ash bucket is provided with a unloading valve, be equiped with a casing by steel frame on the upper end end face of described ash bucket, the clean room that is separated into by card with holes in the end, upper end of described casing, be provided in the pulse jet part on the end face of described clean room upper end, the left end sidewall of described casing is provided with dusty gas inlet, the right-hand member sidewall of described casing is provided with a purified gas outlet that communicates with clean room by the pipeline in the casing, be provided with a winding-up pipe that is communicated with the pulse valve of pulse jet part in the described clean room, described winding-up pipe is provided with spout, be installed on the filter pocket mouths of the filter bag of band filter bag cage bone in the hole on the bottom surface card of described clean room, the filter bag of described band filter bag cage bone is to hang in the casing, be mounted with a conduction type spray nozzle device between the spout of described winding-up pipe and the described filter pocket mouths place, described conduction type spray nozzle device includes the winding-up short tube that connects with the spout of described winding-up pipe, the mozzle that connects with winding-up short tube lower end, the venturi short tube of installing on the filter pocket mouths with respect to the filter bag below the mozzle has certain space between described venturi short tube and the described filter pocket mouths.

Because the present invention has improved existing pulse blowing bag type dust precipitator, spout place at described winding-up pipe is provided with the winding-up short tube, mozzle, filter pocket mouths place with respect to the filter bag below the mozzle also is mounted with the venturi short tube that leaves the space with filter pocket mouths, compressed air passes through the winding-up short tube by the spout ejection in the winding-up pipe, mozzle, the venturi short tube, blow to filter bag at last, when being jetted by spout, compressed air will produce four drainages air-flow on every side, tens times in the clean room ambient gas are introduced in the air-flow, thereby enhancing ash-removal effect, simultaneously, make the winding-up air-flow smooth-going and blow to filter bag equably, and it is impaired to guarantee that filter bag is difficult for.

Description of drawings:

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the structural representation with pulse blowing bag type dust precipitator of conduction type spray nozzle device of the present invention.

Fig. 2 is that schematic diagram is looked on the left side of Fig. 1.

Fig. 3 is the structural representation of the conduction type spray nozzle device of the pulse blowing bag type dust precipitator with conduction type spray nozzle device of the present invention.

Fig. 4 is the user mode schematic diagram of the conduction type spray nozzle device of the pulse blowing bag type dust precipitator with conduction type spray nozzle device of the present invention.

The specific embodiment:

Below with reference to accompanying drawing the pulse blowing bag type dust precipitator with conduction type spray nozzle device of the present invention is described in further detail.

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the pulse blowing bag type dust precipitator with conduction type spray nozzle device of this invention is made up of ash bucket (2), casing (4), clean room (6) and pulse jet part (7).

The end, lower end of described ash bucket (2) is equipped with a unloading valve (1), be fixedly connected by steel frame (3) and casing (4) formation on the upper end end face of described ash bucket (2), be divided into clean room (6) by card (5) in the end, upper end of described casing (4), described card is shaped on the hole on (5), the number in the hole on the described card (5) is chosen by designing requirement, be equipped with pulse jet part (7) on the upper end end face of described clean room (6), be equipped with dusty gas inlet (8) on the left end sidewall of described casing (4), be equiped with a purified gas outlet (9) on the right-hand member sidewall of described casing (4), described purified gas outlet (9) communicates with clean room (6) connection by the pipeline in the casing (4), be installed on a winding-up pipe (10) in the described clean room (6), described winding-up pipe (10) is communicated with the pulse valve of pulse jet part (7), be equipped with spout on the described winding-up pipe (10), described winding-up pipe (10) but on spout a tree name designing requirement of number root and set, be placed with the filter bag (11) of band filter bag cage bone in the hole on the bottom surface card (5) of described clean room (6), the filter pocket mouths of the filter bag (11) of described band filter bag cage bone is the place, hole that is shelved on the described card (5), the filter bag (11) of described band filter bag cage bone is to hang in the casing (4), be equipped with a conduction type spray nozzle device (15) between the filter pocket mouths place of the spout place of described winding-up pipe (10) and described filter bag (11), the winding-up short tube (12) that described conduction type spray nozzle device (15) is connected by the spout place with described winding-up pipe (10), the mozzle (13) that connects with winding-up short tube (12) lower end, be installed in respect to the filter pocket mouths of the filter bag (11) of mozzle (13) below the place and form with venturi short tube (14) that filter pocket mouths has a fixed gap.

Pulse blowing bag type dust precipitator with conduction type spray nozzle device of the present invention is when carrying out clearly dirt to the filter bag surface, to make compressed air in the winding-up pipe, blow to mozzle by the winding-up short tube by the spout place, blow to the venturi short tube again, blow to filter bag at last, in the winding-up process, respectively by the winding-up short tube, mozzle, venturi short tube and filter pocket mouths are everywhere, but gases a large amount of around in the drainage clean room have increased winding-up throughput and intensity in the winding-up air-flow, improved ash-removal effect widely, simultaneously, because of air-flow smooth-going, the filter bag of jetting has equably been avoided filter bag very easily to be blown bad result fully, and has been prolonged the service life of filter bag.
