Technical field
The present invention relates to a kind of sack cleaner nozzle, especially relate to a kind of bag-type dusting metal v-belt laser school
The spray nozzle device of orthofunction.
Background technology
In recent years, the situation is tense for China's atmospheric pollution, pellet (PM10), fine particle (PM2.5)
The Polluted area atmospheric environment problem being characterized becomes increasingly conspicuous, the puzzlement that especially haze weather is brought to common people
The most serious.Along with China's industrialization, the deep propelling of urbanization, energy consumption continues to increase, and air is dirty
Dye preventing and treating pressure continues to strengthen, the atmosphere pollutants emission standards of each industrial trade also increasingly stringent.Carry on the back in the industry
Under scape, sack cleaner is widely used in major part industrial undertaking because of its efficient efficiency of dust collection.
Its operation principle: sack cleaner be utilize filter element (or referred to as filtrate) by the solid-state in dusty gas,
Liquid particulate or harmful gas detention separate or the high-effective dust-removing equipment of absorption.The operating mode of sack cleaner is by filtering
With deashing transient alternately.Proceeding to a certain degree when filtering operating mode, the dust layer of filter material surface is more
Long-pending the thickest, the running resistance of cleaner unit is increasing, processes air quantity more and more less, now has to enter into deashing operating mode,
Filtrate is made again to recover filtering function.The most frequently used purge mode of sack cleaner is pulse jet mode, i.e. utilizes
Compressed gas is deashing medium, compressed gas abrupt release, the deashing air-flow of high velocity jet is lured by spraying and blowing organ
Oneself secondary gas flow of derivative times together sprays into filter bag, so that filter bag is able to deashing.Spraying and blowing organ includes: gas
Bag 11, pulse valve 12, injection tube 1, nozzle A etc. (as shown in Figure 1).When the signal of telecommunication received by pulse valve 12
During unlatching, compressed gas flows to injection tube 1 in abrupt release.Injection tube 1 has some spray orifices (or dress
Have some nozzles), its quantity is identical with the quantity of row's filter bag 13, and each spray orifice (or nozzle) is directed at a filter
The center of bag 13.Compressed gas (deashing air-flow or blast pass) is from spray orifice (or nozzle) ejection at a high speed, same
Time induction be several times as much as oneself ambient gas, and make the energy of two parts gas transmit, mixed gas sprays into filter bag
Thus realizing deashing, dust falls in the ash bucket 14 of sack cleaner D.
There is the inhomogeneities of pressure and flow in the pulse dust cleaning air-flow of each spray orifice of sack cleaner, causes pulse jet
Filter bag corresponding to pipe end spray orifice is the most damaged, and some producer is by being arranged to pre-large post-small by spray orifice bore at present
Two kinds to three kinds bore specifications, thus alleviate the uneven problem of deashing air-flow to a certain extent.But in winding-up
Directly opening different spray orifice bores one on pipe is to produce inconvenience, and two is also cannot to change, to cleaner unit after perforate again
Producer brings no small puzzlement.
There is an air velocity flowed with spray inner axial tube at spray orifice in the deashing air-flow of sack cleaner, causes
There is certain skewness in jetting deashing air-flow, thus causes filter bag top to be skewed air-flow and directly jet and rupture.
Current most cleaner unit producer is all by installing Venturi tube or protection short tube protection on the top of filter bag frame
Filter bag is not skewed air-flow and directly blows brokenly, or welds one section of short tube correcting blast pass, this section of short tube at spray orifice
Under the operating modes such as different pulse valve sizes, jetting pressure, many heavy calibers should be set to respectively and length is not the most fixed
Opinion, air-flow correcting effect is the most undesirable.
Because the inhomogeneities of above-mentioned jetting deashing air-flow and deflection do not obtain basic correction, thus cause mesh
The earlier breakage of the part filter bag being widely present in front sack cleaner and filter bag local lost efficacy.Although can by and
Shi Genghuan filter bag continue ensure sack cleaner properly functioning, but improve cost, have impact on operating efficiency,
Reduce service life.
