Abstract
The invention relates to a nozzle for a bag filter. The nozzle for the bag filter is mounted on a blowing pipe (3) and comprises a nozzle body (2), a nozzle (4) and a flow guiding body (5), wherein the flow guiding body (5) is arranged on the nozzle body (2), a channel with a larger upper end and a smaller lower end is arranged in the flow guiding body (5), and the nozzle (4) is placed in the channel of the flow guiding body and is communicated with the blowing port of the blowing pipe (3). Air-flow is blown into the flow guiding body (5) via the nozzle (4) under guiding, enters from the larger end of the channel in the flow guiding body (5) and flows out from the smaller end of the channel in the flow guiding body (5). Compared with the prior art, the nozzle for the bag filter in the invention has the following advantages: secondary flow guiding effect of the nozzle is utilized, so the air blowing capacity of an ash removal system of the bag filter is greatly improved, and dedusting effect is substantially enhanced.
Description
Technical field
The present invention relates to a kind of pulse valve, particularly a kind of sack cleaner nozzle.
Background technology
Since sack cleaner comes out from the fifties, Jing is widely used both at home and abroad, is updated, in purification dusty gas
Aspect is achieved and is developed on a large scale very much, and as ash-clearing technology is advanced, air cloth ratio is increased substantially, therefore air quantity is big, take up an area face with processing
The features such as accumulating high little, purification efficiency, reliable operation, simple structure, a little repair.Efficiency of dust collection can reach more than 99%, be one
Plant high-effective dust-removing equipment.
Its operation principle is：Dusty gas is by ash bucket（Or bottom spaciousness open type flange）It is into filter chamber, straight compared with coarse granule
Connect and fall into ash bucket or ash silo, dust gas Jing sock filtrations, dust are detained to filter bag surface, net gas Jing bag mouth to air-purifying chamber, by
Blower fan enters air, when the dust on filter bag surface is continuously increased, and causes equipment resistance to rise to setting value, the time relay
（Or elementary errors pressure controller）Output signal, program control instrument are started working, one by one unbalanced pulse valve, make compressed air by spout to filter
Bag carries out jetting deashing, filter bag is expanded suddenly, and in the presence of back draught, the dust for investing filter bag surface departs from rapidly filter
Bag falls into ash bucket（Or ash silo）Interior, dust is discharged by unloading valve, and after whole filter-bag blowing deashings terminate, cleaner unit recovers normal work
Make.
Sack cleaner guides blast pass to enter filter element interior by the perforate in injection tube, makes to be attached to filtration
Powder body on element is peeled off, but ash-removal effect is poor.
The content of the invention
The purpose of the present invention is exactly to provide one kind and be greatly improved and remove to overcome defect that above-mentioned prior art is present
The sack cleaner nozzle of dirt effect.
The purpose of the present invention can be achieved through the following technical solutions：A kind of sack cleaner nozzle, installed in spray
On blowpipe, it is characterised in that including nozzle body, nozzle, drain body, described drain body is arranged on nozzle body, in drain body
Up big and down small passage is provided with, described nozzle is placed in the passage of drain body, and is connected with the injection mouth of injection tube, guide gas
Stream is blown Dao drain body in by nozzle, and air-flow is entered from the big end for drawing fluid passage, and small end flows out.
In up big and down small horn-like, its stub end is fixed on nozzle body described drain body.
The stub end of described drain body and nozzle body integrated setting.
Described nozzle is arranged on nozzle body, and is enclosed in drain body, the port of export of nozzle with draw fluid passage
Small end it is corresponding.
Be connected with ring for fixing on described nozzle body, fixed trap in injection tube, so as to nozzle is fixed on injection tube
On.
Described ring for fixing is bolted on nozzle body.
Compared with prior art, the present invention is arranged a up big and down small drain body outside conventional nozzle, and nozzle sprays
Air-flow enter drain body stub end, then from little head end spray, formed secondary drainage effect, substantially increase sack cleaner
The injection tolerance of soot cleaning system, greatly improves dust removing effects.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
As shown in figure 1, a kind of sack cleaner nozzle, in injection tube 3, including nozzle body 2, nozzle 4, drain
Body 5, in up big and down small horn-like, its stub end is fixed on integrated with nozzle body 2 on nozzle body 2 setting for described drain body 5
Put, in drain body 5, be provided with up big and down small passage, described nozzle 4 is arranged on nozzle body 2 and is placed in the passage of drain body,
And be enclosed in drain body 5, the port of export of nozzle 4 is corresponding with the small end of 5 passage of drain body, described nozzle 4 and injection
The injection mouth connection of pipe 3, guiding air-flow are blown Dao drain body 5 in by nozzle 4, and air-flow is entered from the big end of 5 passage of drain body,
Small end flows out.
Ring for fixing 1 is connected with described nozzle body 2, ring for fixing 1 is enclosed within injection tube 3, so as to nozzle is fixed on spray
On blowpipe.Described ring for fixing 1 is bolted on nozzle body 2.
