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
Sack cleaner is since the fifties comes out, through widely using both at home and abroad, update, achieve in purification dusty gas and develop on a large scale very much, because ash-clearing technology is advanced, air cloth ratio increases substantially, therefore has the features such as process air quantity is large, floor space is little, purification efficiency is high, reliable operation, structure simple, a little repair.Efficiency of dust collection can reach more than 99%, is a kind of high-effective dust-removing equipment.
Its operation principle is: dusty gas enters filter chamber by ash bucket (or the spacious open type flange in bottom), comparatively coarse granule directly falls into ash bucket or ash silo, dust gas is through sock filtration, dust detention is in filter bag surface, pure qi (oxygen) through sack to air-purifying chamber, air is entered by blower fan, dust when filter bag surface constantly increases, when causing equipment resistance to rise to setting value, the time relay (or differential pressure controller) outputs signal, program control instrument is started working, unbalanced pulse valve one by one, compressed air is made to carry out jetting deashing by spout to filter bag, filter bag is expanded suddenly, under the effect of back draught, the dust investing filter bag surface hightails filter bag and falls in ash bucket (or ash silo), dust is discharged by unloading valve, after whole filter-bag blowing deashing terminates, deduster recovers normal work.
Sack cleaner guides blast pass to enter filter element interior by perforate in injection tube, the powder be attached on filter element is peeled off, but ash-removal effect is poor.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and a kind of sack cleaner nozzle that greatly can improve dust removing effects is provided.
Object of the present invention can be achieved through the following technical solutions: a kind of sack cleaner nozzle, be arranged in injection tube, it is characterized in that, comprise nozzle body, nozzle, drainage body, described drainage body is arranged on nozzle body, up big and down small passage is provided with in drainage body, described nozzle is placed in the passage of drainage body, and is communicated with the winding-up mouth of injection tube, guides air-flow to jet in drainage body by nozzle, air-flow enters from the large end drawing fluid passage, and small end flows out.
Big up and small down horn-like of described drainage body, its stub end is fixed on nozzle body.
The stub end of described drainage body and nozzle body integrated setting.
Described nozzle is arranged on nozzle body, and is enclosed in drainage body, and the port of export of nozzle is corresponding with the small end drawing fluid passage.
Described nozzle body is connected with retainer plate, and nozzle in injection tube, thus is fixed in injection tube by fixed trap.
Described retainer plate is bolted on nozzle body.
Compared with prior art, the present invention is at the outer sheathed up big and down small drainage body of the nozzle of routine, the air-flow of nozzle ejection enters drainage body stub end, spray from little head end again, form the effect of secondary drainage, substantially increase the winding-up tolerance of sack cleaner soot cleaning system, dust removing effects is improved greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
As shown in Figure 1, a kind of sack cleaner nozzle, be arranged in injection tube 3, comprise nozzle body 2, nozzle 4, drainage body 5, big up and small down horn-like of described drainage body 5, its stub end be fixed on nozzle body 2 with nozzle body 2 integrated setting, up big and down small passage is provided with in drainage body 5, described nozzle 4 be arranged on nozzle body 2 is placed in drainage body passage in, and be enclosed in drainage body 5, the port of export of nozzle 4 is corresponding with the small end of drainage body 5 passage, described nozzle 4 is communicated with the winding-up mouth of injection tube 3, air-flow is guided to jet in drainage body 5 by nozzle 4, air-flow enters from the large end of drainage body 5 passage, small end flows out.
Described nozzle body 2 is connected with retainer plate 1, and retainer plate 1 is enclosed within injection tube 3, thus is fixed in injection tube by nozzle.Described retainer plate 1 is bolted on nozzle body 2.
