Description
Technical field
The utility model relates to dedusting technology field more particularly to a kind of band deflector hole sprays for pulsed jet cloth filter
Mouth device.
Background technique
Cause today of environmental degradation in industry rapid development, the improvement and protection of environment are most important, and pulse bag removes
For dirt technology maturation in last century the nineties, it is the major product for being used for industrial dedusting now, in the overall structure of deduster
Defect is still remained to have much room for improvement.
Pulsed jet cloth filter is equipped with injection tube above filter bag, has several injection holes and nozzle to fill in each injection tube
It sets, each injection hole is directed at a filter pocket mouths, and the air pulse that when deashing sprays from pulse valve passes through injection hole and spray nozzle device
Jet-action inject filter bag, dust releasing under the action of inverted draft on filter bag, to complete deashing process.
Existing spray nozzle device is fairly simple, and 1 steel pipe is only arranged, after high-speed pulse blast pass is by spray nozzle device,
Air-flow expands to form jet stream to surrounding along blowing axis, then sprays to filter bag, because spray nozzle device is shorter to filter bag distance, sucks gas
It measures limited, causes too fast in filter pocket mouth portions region flow velocity, but flow is too small, is easy for filter pocket mouths to be blown and damage, and causes
Each pulse valve blowing filter bag quantity is reduced, and finally makes the reduction of filter bag of dust collector service life, and use cost increases, and for up to
To identical blowing area, it is desirable that dust remover blowing systems increase, increase equipment cost.
Utility model content
The purpose of the utility model is to overcome defect of the existing technology, provide that a kind of service life increases, cost subtracts
The band deflector hole spray nozzle device for pulsed jet cloth filter small, that blowing tolerance can be increased.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of band for pulsed jet cloth filter
Deflector hole spray nozzle device connects inside the nozzle and injection tube including injection tube and several nozzles being uniformly arranged along injection tube
It is logical, deflector hole is offered respectively on the nozzle.
Preferably, the one end of nozzle close to injection tube is arranged in the deflector hole.
In one preferred embodiment of the utility model, a pair of of deflector hole is symmetrically arranged on the nozzle.
In the utility model another preferred embodiment, several deflector holes are evenly arranged on the nozzle.
It installs and fixes for the ease of nozzle, the nozzle includes the diversion division and interconnecting part being wholely set, the interconnecting part
It is passed through in injection tube, the deflector hole is arranged on diversion division.
In order to reach preferably blowing tolerance, the diameter of the diversion division is greater than the diameter of interconnecting part.
The utility model has the following beneficial effects:
The band deflector hole spray nozzle device for pulsed jet cloth filter of the utility model is led due to offering on nozzle
Discharge orifice can increase spray nozzle device blowing tolerance, keep the entire exit region flow velocity of spray nozzle device balanced, effect is in balanced flow velocity
It can guarantee that filter pocket mouths are not easy blowing damage under jet action, each pulse valve blowing filter bag quantity will greatly increase, and use the longevity
Life increase, to reach identical blowing area, it is desirable that dust remover blowing system it is smaller, reduce equipment cost.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram with deflector hole spray nozzle device that the utility model is used for pulsed jet cloth filter；
Fig. 2 is the structural schematic diagram of the nozzle of the utility model；
Wherein: 1. injection tubes, 2. nozzles, 3. deflector holes, 4. interconnecting parts, 5. diversion divisions.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be understood by those skilled in the art with feature, to make apparent specific boundary to the protection scope of the utility model
It is fixed.
As shown in Figure 1, a kind of band deflector hole spray nozzle device for pulsed jet cloth filter, including injection tube 1 and along spray
It is connected to inside several nozzles 2 that blowpipe 1 is uniformly arranged, the nozzle 2 and injection tube 1, offers water conservancy diversion respectively on the nozzle 2
Hole 3.
Show that the deflector hole 3 is preferably disposed at nozzle 2 close to one end of injection tube 1, Ke Yida by test of many times
To optimal blowing tolerance.
Preferably, being symmetrically arranged with a pair of of deflector hole 3 on the nozzle 2, two deflector holes 3 form a pair of of through-hole.
Certainly, several deflector holes 3 can also be evenly arranged with, on nozzle 2 to improve blowing tolerance.
As shown in Fig. 2, the nozzle 2 includes the diversion division 5 and interconnecting part 4 being wholely set, the interconnecting part 4 is passed through blowing
In pipe 1, the deflector hole 3 is arranged on diversion division 5, and the diameter of the diversion division 5 is greater than the diameter of interconnecting part 4.I.e. nozzle 2 is in
Ladder-like, the small end interconnecting part 4 of nozzle 2 is inserted into injection tube 1, and nozzle 2 is detachably connected by interconnecting part 4 with injection tube 1.
The utility model is used for the band deflector hole spray nozzle device of pulsed jet cloth filter due to offering water conservancy diversion on nozzle 2
Hole 3, when high-speed pulse blast pass passes through spray nozzle device, because jet action at deflector hole 3 there are larger negative pressure, make water conservancy diversion
3 ambient gas of hole enters spray nozzle device under the action of negative pressure, can finally increase spray nozzle device blowing tolerance, keep spray nozzle device entire
Exit region flow velocity is balanced, effect be can guarantee that filter pocket mouths are not easy blowing damage under balanced flow velocity jet action, and
Because of band deflector hole 3, spray nozzle device considerably increases blowing tolerance, and each pulse valve blowing filter bag quantity will greatly increase, and uses
Service life increase, to reach identical blowing area, it is desirable that dust remover blowing system it is smaller, reduce equipment cost.
It should be appreciated that specific embodiment described above is only used for explaining the utility model, it is not used to limit this reality
With novel.By the utility model the obvious changes or variations extended out of spirit still in the utility model protection
Among range.
