Description
Technical field
The utility model relates to dust arrester technical field, particularly, relates to a kind of pulse bag type dust collector filtration facility of structure optimization.
Background technology
It is high that pulse bag type dust collector has purification efficiency, the advantages such as process gas capacity is large, stable performance, easy to operate, maintenance load is little.During dusty gas is entered by deduster air inlet, lower box, dirt gas is separated by the various effect effects that dusty gas is entered due to filter bag in upper box process by filter bag, dust is attracted on filter bag, and gas enters upper box through filter bag through Venturi tube, discharges from air outlet.Dusty gas by the purification process of filter bag, the long-pending dust be attached on filter bag gets more and more along with the increase of time, is added the resistance of filter bag, causes and reduced gradually by filter bag gas flow.For normal work, control resistance within the specific limits, deashing must be carried out to filter bag once overrun, by pulse control instrument sequence trigger switch each control valve unbalanced pulse valve during deashing, blast injection in gas bag is in filter bag, filter bag moment sharply expands, and make the long-pending dust releasing being attached to filter bag surface, filter bag restPoses.Clear lower dust falls into ash bucket, discharges body through dust removing system.Make the long-pending dust pulse jetting deashing be periodically attached on filter bag thus, make Purge gas normal through, ensure that dust pelletizing system is run.
Pulse jet method is a kind of purge mode that in current sack cleaner industry, deashing ability is stronger.During pulse dust cleaning, the secondary gas flow that compressed air is induced together with it sprays into filter bag in very short time, make filter bag by the expansion produced at the bottom of sack to bag sharply, contraction and impact shock, air-flow sprays from inside to outside simultaneously, thus make the dust layer on filter bag because coming off from filter bag by effect of inertia, reach the object of deashing.Dust releasing mainly relies on the expansion of filter bag, contraction and vibration, and the filter bag of prior art is all adopt single cylinder type filter cloth structure, filter cloth telescopic level is little, and along with the continuous passing of filtering, filter bag can because of the expansion of high frequency time, Shrinkage behavior and breakage occurs.In addition, the structure of existing filtration facility causes mounting process to require, and operating personnel carry out the installation of filter bag, cage respectively above card via card hole, this not only requires to provide enough operating spaces above card, also requires that at least two people operate simultaneously, installs inconvenient.Therefore, for alleviating the breakage that filter bag causes because expanding, shrinking and the fussy degree reducing filter bag, cage mounting process, need to improve filter bag, cage contour structures and mounting means.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of pulse bag type dust collector filtration facility reducing filter bag wearing and tearing, convenient installation, structure optimization.
The technical scheme in the invention for solving the above technical problem is:
A kind of pulse bag type dust collector filtration facility of structure optimization, comprise filter bag and cage, described filter bag is lower end closure, the cylinder type of upper end open, the filter bag upper end open of cylinder type is air outlet A, cage is built in filter bag, the upper end of cage is welded with flange, flange is circumferentially evenly equipped with bolt eyelet, cage is fixedly connected with card by flange, flange is provided with air outlet B, the end face of the side of Flange joint cage is provided with the convex annular edge for installing filter bag, convex annular edge is positioned at the periphery of the bolt eyelet of flange, the upper end of filter bag is provided with elasticity ring plate, elasticity ring plate is fixedly installed in convex annular along upper, the cylinder type sidewall of filter bag is circumferentially evenly equipped with alternately to filter bag inner recess with to filter bag outer projection, the fold extended vertically.
Compared with conventional facilities, filter bag of the present utility model adopts the design of similar pleated curtain, cage is fixed by the bolt eyelet of the flange of cage welded top and card, the bouffancy type design of filter bag improves the elasticity capacity of filter bag reply high velocity air impact, reduce filter bag because acutely expanding, shrinking to self pull, frictional force, reduce filter cloth unit are stressed, during pulse jet, though there is violent expansion, shrink and vibration in filter bag, but because of the buffering of filter bag fold, reduce the wearing and tearing that filter bag itself is subject to, thus reduce filter bag usage quantity.
Filtration facility overall structure and mounting means simple, cage is fixed by flange and card, thus, different from traditional cage mounting means, cage in the utility model impulse bag filter filtration facility is no longer installed downwards via card hole by above card, operating personnel can singlely be installed fixing below card by flange and card, cage and filter bag are installed, without the need to climbing above card, save height and the manpower of card superjacent air space, prepared screw-bolt hole is needed during card design, this cage mounting means stablizing effect is better, install simple, can one man operation, and operating personnel can install integral filter facility without the need to climbing above card, save the height of card superjacent air space.
Preferably, the cylindrical outer wall of described elasticity ring plate is provided with annular slot, the inner cylindrical sidewall on the convex annular edge of flange is provided with annular lug, annular slot is fixed on annular lug, realize the fixing of filter bag and flange, be installed on the structure of card bore edges compared with conventional filter bag, this filter bag mounting means is more conducive to maintenance and the replacing of filter bag, saves the loaded down with trivial details of dismounting cage.
Preferably, described flange is screwed flange.
To sum up, the beneficial effects of the utility model are:
The filter bag of the utility model band fold improves the elasticity capacity of filter bag reply high velocity air impact, reduce filter bag because acutely expanding, shrinking to self pull, frictional force, reduce filter cloth unit are stressed, during pulse jet, though there is violent expansion, shrink and vibration in filter bag, but because of the buffering of filter bag fold, reduce the wearing and tearing that filter bag itself is subject to, thus reduce filter bag usage quantity.
The flange on cage top is conducive to operating personnel and installs cage and filter bag below card, saves manpower and card superjacent air space; Deduster filtration facility structure of the present utility model is simple, and small investment is easy for installation, during for pulse feature deduster, can slow down the degree of wear of gases at high pressure to filter bag, extends the service life of filter bag.
By the enforcement of this utility model patent, the installation of pulse bag type dust collector filtration facility becomes more simple, and the filter bag wear phenomenon that deduster brings because of pulse jet will reduce greatly, saves filter bag cost.
