Description
Technical field
The present invention relates to a kind of bag dust-collector pulse jetting cleaning device, particularly for a kind of pulse jetting deashing device of field of Environment Protection sack cleaner deashing.
Background technology
Pulse bag type dust collector is that the filter bag utilizing filtering material to make filters dusty gas, makes the cleaner that dust is separated from gas.When sack cleaner runs, filter bag surface dust is cumulative, and filtration resistance is also more and more higher, and when resistance reaches setting value, sack cleaner should carry out deashing.Traditional pulse dust cleaning mode realizes by pulse valve (it comprises magnetic valve, diaphragm, valve body, valve seat etc.) work, namely control system provides a signal of telecommunication, the magnetic valve of pulse valve is powered, diaphragm is shifted, open blast pipe, the Compressed Gas be stored in gas bag discharges from blast pipe, by the nozzle in an injection tube to corresponding row's filter-bag blowing deashing; Control system provides a signal of telecommunication again, magnetic valve dead electricity, and diaphragm resets, and cover exhaust pipe mouth, this pulse valve quits work, and completes a deashing process.By that analogy, each pulse valve takes turns to operate, the structure of traditional pulse jetting deashing device common in engineering that Here it is and principle.
Be not difficult to find out that above traditional deashing device exists three problems: one is that each pulse valve can only to row's filter bag ash removal, and when filter bag One's name is legion, pulse valve consumption is large, and equipment cost is high, and maintenance workload is large; Compressed air in two gas bags when being each deashings is only from an injection tube release, winding-up tolerance is often excessive, and winding-up intensity is uncontrollable, and after deashing, filter bag surface is too clean, easily cause PM2.5 minuteness particle to penetrate escape when refiltering, affect the arresting efficiency of deduster to minuteness particle; Three intensity of winding-up when being deashings are excessive, can shorten the service life of filter bag.
Summary of the invention
The object of the invention is, for traditional deashing device Problems existing, to propose a kind of pulse jetting deashing device of brand new, be mainly used in sack cleaner deashing.
Technical solution of the present invention proposes a kind of new pulse jetting deashing device, comprise air receiver housing, divide gas tank housing, air receiver end socket is welded with at air receiver housing two ends, a point gas tank end socket is welded with at point gas tank housing two ends, between air receiver housing and point gas tank housing, establish flat partition board, in point gas tank housing, set up dividing plate; Air receiver housing, flat partition board and air receiver end socket form an air receiver space; Air receiver housing is installed the blast pipe of pulse valve and equivalent amount, a termination pulse valve of blast pipe, the other end is welded on flat partition board; Flat partition board, vertical dividing plate, point gas tank housing and point gas tank end socket is utilized to form a point gas tank space, blast pipe UNICOM air receiver space and point gas tank space; Perforate on point gas tank housing in point gas tank space of each formation, install gas-distributing pipe, on gas-distributing pipe, grafting injection tube, injection tube configures nozzle; Air receiver housing establishes air inlet pipe.
The air receiver space of device of the present invention is communicated with, compressed (such as compressed air); The length of air receiver housing is variable, and the pulse valve installed and the quantity of blast pipe are variable, and the quantity of the pulse valve that the length according to air receiver housing is installed and blast pipe is 5 ~ 20.
Device of the present invention, point gas tank space utilizing vertical dividing plate to be formed is identical with the quantity of blast pipe with pulse valve, and a point gas tank space is disconnected, not holding compressed air.The quantity of the gas-distributing pipe that point gas tank housing in point gas tank space of each formation is installed is greater than 1, and according to the length of injection tube, its nozzle quantity configured above is greater than 1.
When a pulse valve job, simultaneously to many injection tube air feed, can namely realize the many sprays of a valve.This is the feature not available for traditional blowing device, and changing traditional blowing device blowing valve can only to the present situation of an injection tube winding-up.
Device of the present invention, by arranging blast pipe, establish contacting between air receiver space and point gas tank space, namely after the diaphragm of pulse valve is opened, Compressed Gas first-selection in air receiver space is discharged into a point gas tank space by blast pipe, be redistributed to many injection tubes, jetting deashing is carried out to filter bag.
The operation principle of device of the present invention is: the Compressed Gas for jetting deashing enters air receiver space from air inlet pipe; When sack cleaner running resistance rises to setting value, control system sends a signal of telecommunication to one of them pulse valve, the magnetic valve of pulse valve is powered, diaphragm is shifted, open the exhaust outlet of blast pipe, the compressed air be stored in gas bag is discharged into a point gas tank space from blast pipe, and filter bag is counter cleans to many rows to be redistributed to many injection tubes; Control system gives a signal of telecommunication again, the magnetic valve dead electricity of pulse valve, and diaphragm resets, and cover the exhaust outlet of blast pipe, this pulse valve quits work, and completes a deashing process.By that analogy, other pulse valve takes turns to operate.
The pulse jetting deashing device that the present invention proposes, because a point gas tank space has blowing gas distribution function, namely tolerance of jetting and winding-up energy can be assigned on many gas-distributing pipes, change traditional blowing device blowing gas only from an injection tube release, jet large-minded, the uncontrollable shortcoming of winding-up intensity.According to the characteristic of flue dust and filtrate, the quantity of the gas-distributing pipe that point gas tank housing is arranged can change, and can be 2,3 ... n root.Select gas-distributing pipe 6 quantity different, also different with intensity to the deashing tolerance of filter bag, achieve the adjustment of deashing tolerance and intensity.The position of gas-distributing pipe 6 can in the side of point gas tank housing, also can in the bottom surface of point gas tank housing.
Pulse jetting deashing device proposed by the invention, the length of injection tube can change, and the quantity of nozzle also can change, and combines with gas-distributing pipe, can realize the accurately control further of winding-up tolerance and winding-up intensity, this is the progress on traditional blowing device.
Pulse jetting deashing device proposed by the invention, the cross section in its air receiver space formed and point gas tank space can be rectangle, also can be semicircle or circular arc, is of value to and improves housing compressive resistance and reduce distortion.
Beneficial effect of the present invention: this device overcomes that the pulse valve quantity that traditional pulse jetting deashing device exists is many, large-minded, winding-up intensity uncontrollable defect of jetting, have that structure is simple, characteristics of compact layout, low cost of manufacture, feature that winding-up intensity is adjustable.Compared with traditional pulse jetting deashing device, this device can realize a pulse valve to many row's filter bags jetting deashing simultaneously, reduces the consumption of pulse valve, reduces deduster cost of manufacture; Can control winding-up tolerance and winding-up intensity, its importance is to avoid the excessive deashing of filter bag, and filter bag surface is too clean, causes PM2.5 minuteness particle to penetrate escape, improves deduster to the arresting efficiency of minuteness particle, extends life-span of the filter bag simultaneously.
