Background technology:
In traditional negative pressure off-line pulsed jet cloth filter, the off-line lift valve is that the normally closed type forward is arranged, deduster is when work, if the compressed air of lift valve cylinder is under-supply, to make all lift valves be in the nature normally off, the filtration channel of dedusting will all stop up, the pipe network system of dedusting will be cut off naturally, the negative pressure of blower fan acts on filter bag of dust collector rear portion and the airduct fully, can cause deduster and airduct to become flat, the safety of harm equipment, even Workshop Production technology and production equipment caused adverse effect, and perhaps in order to guarantee the safety of deduster, the deduster of stopping using, but this will cause environmental pollution or influence to produce, and this drawback be never had the good technical scheme solve.
Summary of the invention:
The purpose of anti-flat formula off-line pulsed jet cloth filter of the present invention and ash removal method is to overcome the deficiencies in the prior art, a kind of technology that lift valve oppositely is installed on the air-out passage ledger board of deduster upper box bottom is provided, opening of the lift valve of change control air-out channel air flow, close mode, give lift valve cylinder input compressed air, the control lift valve cuts out, the disconnected compressed air of putting or weaken lift valve, the control lift valve is opened, guarantee that deduster is in normal operating conditions all the time, all the time normal deashing, prevent that deduster housing and pipeline from because of the blower fan negative pressure becomes flat, having prolonged the service life of deduster.
Purpose of the present invention is realized by following manner: by upper box, middle casing, ash bucket, the column filter bag, the winding-up pipe, lift valve, middle casing air-out passage, middle casing air intake passage inclined clapboard, blast pipe, discharge pipe and cat ladder constitute, if upper box, middle casing is tightly connected below the upper box, in the middle casing filter bag is installed, the filter bag upper end is fixed on the card hole of card, seal welding collar tie beam below the middle casing, seal welding ash bucket below the collar tie beam, unloading valve is tightly connected below the ash bucket, set up post respectively for four jiaos, on the collar tie beam during the column upper end is fixed between casing and the ash bucket, the lower end is fixed on the ground pedestal of deduster, cat ladder top is installed in the deduster on the wallboard of casing and the upper box outside, the upper end of bottom is fixed on the support of collar tie beam and column by support, its lower end is fixed on the ground cement pedestal, the rigidity valve seat oppositely is installed in the bottom of air-out passage ledger board, the rigidity valve plate is installed in the lower end of valve rod, the upper end of valve rod is connected with the axle of cylinder, cylinder is fixed on the upper box top board, compressed air piping one end connects the other end of compressed air gas source and is connected with each lift valve cylinder respectively, the winding-up bend pipe of managing with on the gas bag of jetting is connected, each air intake branch one end connects the inlet manifold, an other end ash bucket, discharge pipe one end connects the air-out passage, an other end is communicated with negative-pressure air fan, and negative-pressure air fan is communicated with chimney.
The operation principle of lift valve oppositely is installed: the operation principle of lift valve is to utilize the elastoplasticity principle of the steel plate that constitutes the rigidity valve plate, alternation principle to guarantee the valve plate of lift valve and the sealing between the rigidity valve seat.
The course of work of lift valve oppositely is installed: the compressed air that is provided by compressed air gas source passes through the cylinder that compressed air piping is sent into lift valve, not enough even when dying when compressed air air pressure that compressed air gas source provided, all lift valve rigidity valve plates on the deduster descend naturally, all lift valves are opened naturally, deduster is work as usual, deashing control program by dust pelletizing system electrical control module PLC, automatically enter the online ash removal program, the lifting action of valve rod by cylinder promotes the rigidity valve plate of valve rod lower end and put down, closed and the unlatching with the steel valve seat, thereby control closing and opening of air-out passage, the valve rod that the cylinder of lift valve promptly oppositely is installed promotes downwards, drive the short tube that the steel valve plate leaves the steel valve seat, open air-flow control lift valve, valve rod is upwards mentioned, drive the steel valve plate and draw close the short tube of steel valve seat, closed gas flow control lift valve, the control lift valve opens and closes.
The dusty gas filter process: dusty gas is distributed to each air intake branch, filtration by filter bag by the inlet manifold, dust is separated from air, go forward side by side into ash bucket, unload by unloading valve, purify air from the filter bag inwall enter filter back air duct, through the switch control of lift valve, discharge by chimney at last by flow through air-out passage, discharge pipe, negative-pressure air fan of the short tube of valve seat.
Deashing process: gas bag provides deashing winding-up pressure-air for the winding-up pipe, the electromagnetic pulse control valve of gas bag carries out online jetting deashing on the control deduster, when compressed air air pressure that compressed air gas source provided is in normal condition, deashing control program by dust pelletizing system electrical control module PLC, enter off-line sub-room cleaning program, the electromagnetic pulse control valve of gas bag carries out off-line locellus jetting deashing on the control deduster.
Anti-flat formula off-line pulsed jet cloth filter of the present invention and ash removal method, solved the conventional art dust pelletizing system because the compressed air air pressure that compressed air gas source provided is not enough even when dying, producing the lift valve valve plate descends naturally, all lift valves cut out naturally, the filtration channel of dedusting all stops up, the pipe network system of dedusting is cut off, the negative pressure of blower fan acts on filter bag of dust collector rear portion and the airduct fully, cause deduster to become flat, the technical barrier that situation took place of harm deduster safety, make dust pelletizing system can be not enough even not die and cause deduster body and wind pipe to become flat or stop dust pelletizing system work, influence the situation generation that deduster is used enterprise's ordinary production order even harm workers ' health because of compressed air air pressure.
Anti-flat formula off-line pulsed jet cloth filter of the present invention and ash removal method also comprise the anti-flat formula off-line pulsed jet cloth filter of back-to-back, shared air intake passage and shared air-out channel design type, the i.e. anti-flat formula off-line pulsed jet cloth filter of Y-axis symmetric arrays structure.
Adopt its beneficial effect of the present invention to be: to guarantee that deduster is in normal operating conditions all the time, guaranteed deduster normal deashing all the time, prolonged the service life of deduster.
