Abstract
The utility model relates to a spray nozzle for a bag type dust filter. The spray nozzle is mounted on a spray pipe (3) and comprises a spray nozzle body (2), a spray nozzle head (4) and a drainage body (5), wherein the drainage body (5) is arranged on the spray nozzle body (2), and a channel with a large upper part and a small lower part is formed in the drainage body (5); the spray nozzle head (4) is arranged in the channel of the drainage body (5) and is communicated with the spray opening of the spray pipe (3). Airflow is guided to be sprayed into the drainage body (5) through the spray nozzle head (4), and the airflow enters from the large end of the channel of the drainage body (5) and flows out from the small end of the channel. Compared with the prior art, the spray nozzle has the advantages that the secondary drainage effect of the spray nozzle is utilized, so that the sprayed air flow of the dust cleaning system of the bag type dust filter is greatly increased, and the dust removal effect is greatly improved.
Description
Technical field
The utility model 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 being widely used both at home and abroad, update, aspect purification dusty gas, obtaining very great development, due to ash-clearing technology advanced person, air cloth ratio increases substantially, therefore have the features such as the air quantity of processing is large, floor space is little, purification efficiency is high, reliable operation, simple in structure, 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), directly fall into ash bucket or ash silo compared with coarse granule, dust gas filters through filter bag, dust detention is in filter bag surface, pure qi (oxygen) arrives air-purifying chamber through sack, enter atmosphere by blower fan, when the dust on filter bag surface constantly increases, while causing equipment resistance to rise to setting value, the time relay (or differential pressure controller) output signal, program control instrument is started working, unbalanced pulse valve one by one, make compressed air carry out jetting deashing by spout to filter bag, filter bag is expanded suddenly, under the effect of back draught, the dust that invests filter bag surface hightails filter bag and falls in ash bucket (or ash silo), dust is discharged by unloading valve, after all filter-bag blowing deashing finishes, deduster recovers normal work.
Sack cleaner enters filter element inside by the guiding of perforate in injection tube winding-up air-flow, and the powder that makes to be attached on filter element is peeled off, but ash-removal effect is poor.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of sack cleaner nozzle that can greatly improve dust removing effects in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model 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, in drainage body, be provided with up big and down small passage, described nozzle is placed in the passage of drainage body, and is communicated with the winding-up mouth of injection tube, and guiding air-flow is jetted in drainage body by nozzle, air-flow enters from the large end that draws 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 that draws fluid passage.
On described nozzle body, be connected with retainer plate, fixed trap in injection tube, thereby nozzle is fixed in injection tube.
Described retainer plate is bolted on nozzle body.
Compared with prior art, the utility model is a sheathed up big and down small drainage body outside conventional nozzle, the air-flow of nozzle ejection enters drainage body stub end, hold ejection from microcephaly again, form the effect of secondary drainage, the winding-up tolerance that has greatly improved sack cleaner soot cleaning system, improves dust removing effects greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Fig. 1～2, 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 is fixed on nozzle body 2 and nozzle body 2 integrated setting, in drainage body 5, be provided with up big and down small passage, described nozzle 4 is arranged in the passage that is placed in drainage body on nozzle body 2, and be enclosed in drainage body 5, the port of export of nozzle 4 is corresponding with the small end of drainage body 5 passages, described nozzle 4 is communicated with the winding-up mouth of injection tube 3, guiding air-flow arrives in drainage body 5 by nozzle 4 winding-ups, air-flow enters from the large end of drainage body 5 passages, small end flows out.
On described nozzle body 2, be connected with retainer plate 1, retainer plate 1 is enclosed within injection tube 3, thereby nozzle is fixed in injection tube.Described retainer plate 1 is bolted on nozzle body 2.
