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 to utilize the filter bag that filtering material is made to filter dusty gas, makes the cleaner of dust separation from gas.During sack cleaner operation, 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.By pulse valve (it comprises magnetic valve, diaphragm, valve body, valve seat etc.), work realizes traditional pulse dust cleaning mode, be that control system provides a signal of telecommunication, the magnetic valve of pulse valve is subject to electricity, diaphragm displacement, open blast pipe, the Compressed Gas being stored in gas bag discharges from blast pipe, by the nozzle in an injection tube, to corresponding one, arranges filter-bag blowing deashing; Control system provides a signal of telecommunication again, magnetic valve dead electricity, and diaphragm resets, and covers exhaust pipe mouth, and this pulse valve quits work, and completes a deashing process.By that analogy, each pulse valve takes turns to operate, the structure of common traditional pulse jetting deashing device and principle in engineering that Here it is.
Be not difficult to find out that above traditional deashing device exists three problems: the one, each pulse valve can only be 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; The 2nd, compressed air during each deashing in gas bag only discharges from an injection tube, winding-up tolerance is often excessive, and winding-up intensity is uncontrollable, and after deashing, filter bag surface is too clean, while refiltering, easily cause PM2.5 minuteness particle to penetrate escape, affect the arresting efficiency of deduster to minuteness particle; The 3rd, the intensity of jetting during deashing is excessive, can shorten the service life of filter bag.
Summary of the invention
The object of the invention is the problem existing for traditional deashing device, propose a kind of pulse jetting deashing device of brand new, be mainly used in sack cleaner deashing.
Technical solution of the present invention is to propose a kind of new pulse jetting deashing device, comprise air receiver housing, divide gas tank housing, at air receiver housing two ends, be welded with air receiver end socket, at minute gas tank housing two ends, be welded with a minute gas tank end socket, between air receiver housing and minute gas tank housing, establish flat partition board, in minute gas tank housing, set up dividing plate; Air receiver housing, flat partition board and air receiver end socket form an air receiver space; The blast pipe of pulse valve and equivalent amount is installed on air receiver housing, a termination pulse valve of blast pipe, the other end is welded on flat partition board; Utilize flat partition board, vertical dividing plate, minute gas tank housing and minute gas tank end socket to form a minute gas tank space, blast pipe UNICOM air receiver space and minute gas tank space; Perforate on minute gas tank housing that divides gas tank space of each formation, installs gas-distributing pipe, and the injection tube of pegging graft on gas-distributing pipe configures nozzle in injection tube; On air receiver housing, establish 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 of installing and the quantity of blast pipe are variable, and the pulse valve of installing according to the length of air receiver housing and the quantity of blast pipe are 5 ~ 20.
Device of the present invention, minute gas tank space that utilizes vertical dividing plate to form is identical with the quantity of pulse valve and blast pipe, and a minute gas tank space is disconnected, does not store compressed air.The quantity of the gas-distributing pipe of installing on minute gas tank housing that divides gas tank space of each formation is greater than 1, and according to the length of injection tube, its nozzle quantity configuring is above greater than 1.
When a pulse valve job, can, simultaneously to many injection tube air feed, realize a valve and spray more.This is the not available feature of traditional blowing device, has changed the present situation that blowing valve of traditional blowing device can only be jetted to an injection tube.
Device of the present invention, by blast pipe is set, set up contacting between air receiver space and minute gas tank space, after being the diaphragm unlatching of pulse valve, Compressed Gas first-selection in air receiver space is discharged into a minute gas tank space by blast pipe, be redistributed to many injection tubes, filter bag is carried out to jetting deashing.
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 subject to electricity, diaphragm displacement, open the exhaust outlet of blast pipe, the compressed air being stored in gas bag is discharged into a minute gas tank space from blast pipe, is redistributed to many injection tubes and cleans many rows filter bag is counter; Control system is given a signal of telecommunication again, the magnetic valve dead electricity of pulse valve, and diaphragm resets, and covers the exhaust outlet of blast pipe, and 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 minute gas tank space has blowing gas distribution function, the tolerance of jetting and winding-up energy can be assigned on many gas-distributing pipes, changed traditional blowing device blowing gas only from an injection tube, discharge, 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 arranging on minute gas tank housing can change, and can be 2,3 ... n root.Select gas-distributing pipe 6 quantity different, also different to the deashing tolerance of filter bag and intensity, realized the adjusting of deashing tolerance and intensity.The position of gas-distributing pipe 6 can be in the side of minute gas tank housing, also can be in the bottom surface of minute 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 further accurately controlling 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 the air receiver space of its formation and minute gas tank space can be rectangle, can be also semicircle or circular arc, is of value to and improves housing compressive resistance and reduce distortion.
Beneficial effect of the present invention: this device has overcome that the pulse valve quantity that traditional pulse jetting deashing device exists is many, large-minded, the uncontrollable defect of the intensity of jetting of jetting, has simple in structure, characteristics of compact layout, low cost of manufacture, feature that winding-up intensity is adjustable.Compare with traditional pulse jetting deashing device, this device can be realized a pulse valve to many rows filter bag while jetting deashing, 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 the arresting efficiency of deduster to minuteness particle, extends life-span of the filter bag simultaneously.
