Description
Technical field
The utility model relates to a kind of industrial deduster, refers in particular to a kind of rotary counter-blowing flat bag deduster.
Background technology
Present domestic common used in industry deduster is a pulse bag type dust collector, and pulse bag type dust collector adopts the pulse of compressed air deashing device to carry out deashing, to remove the laying dust on the filter bag.The shortcoming that adopts the pulse of compressed air deashing device to carry out deashing is: be subjected to the restriction of use occasion gas source condition bigger; The device consumable accessory is more, operational reliability is not high, difficult in maintenance; The operating distance of pulse of compressed air blowing is shorter, is not suitable for adopting long filter bag, influences the space availability ratio of deduster.
The utility model content
The technical problems to be solved in the utility model is: existing as defective pointed in the background technology in order to overcome existing industrial pulse bag type dust collector, and provide a kind of rotary counter-blowing flat bag deduster, this rotary counter-blowing flat bag deduster occupation of land is little, space availability ratio is high, simple and convenient operation and maintenance, and the operation of its reverse gas cleaning device is not subjected to the restriction of use occasion gas source condition.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of rotary counter-blowing flat bag deduster, include filtration barrel body, loam cake and the ash bucket of being with bearing, loam cake, ash bucket respectively with filtration barrel body on, the lower end is affixed, filtration barrel body has tangential air inlet, the ash bucket bottom is provided with discharger, loam cake has the air outlet that disposes air-introduced machine, axis with filtration barrel body in filtration barrel body is that the center line circular row is provided with some filter bags that supported by the skeleton pipe, filter bag is coated on the skeleton pipe, air guide hole and a card that has the fancy top that adapts with many skeleton pipe air guide hole shapes and size of many skeleton pipes are affixed, described loam cake has the reverse gas cleaning device, the reverse gas cleaning device includes the turning arm of band winding-up pipe, reducing motor, back blowing machine and differential pressure transmitter, the corresponding fancy top that pastes card of the nozzle of winding-up pipe, the nozzle of winding-up pipe is corresponding with the fancy top shape and the size of card, turning arm is driven by the reducing motor that is arranged at the loam cake top, back blowing machine is located at the loam cake caping, the blowing mouth of back blowing machine is communicated with the air intake vent in the blowback air port of turning arm, the inlet scoop of back blowing machine communicates with the airtight connection of last cover cavity or with outside atmosphere, differential pressure transmitter with advance, the corresponding interface of the airduct at air outlet place connect and with the back blowing machine Electricity Federation.The course of work of this rotary counter-blowing flat bag deduster is: dusty gas tangentially enters filtration barrel body by air inlet, and bulky grain and cohesion grit fall into ash bucket in the effect of centrifugal force and self gravitation, finish the primary dust removing process; The air-flow of carrying fine dust secretly filters the fancy top outflow of back from card via filter bag, comes together in cover cavity (or claiming clean room), is inhaled by the air-introduced machine at air outlet place to be disposed in the atmosphere; Deduster is after operation a period of time, filter bag in its filtration barrel body can cause windage to increase gradually because of laying dust stops up, air outlet pressure reduces, when differential pressure transmitter detects into, when pressure reduction reaches the higher limit of setting in the airduct at air outlet place, just send the startup signal to back blowing machine, the air-flow that back blowing machine blows out is jetted to the fancy top of card via the winding-up pipe of turning arm, stop filtered airflow that flows out from fancy top and the pressure working condition that changes filter bag, thereby cause the filter bag vibration, shake off laying dust, under the rotational action of turning arm, the winding-up pipe carries out blowback one by one to each filter bag, when the windage of filter bag drops to the lower limit of setting, detect signal and close signal by differential pressure transmitter equally to the back blowing machine transmission, deduster enters normal filter once more.
Filter bag in the direct impact filtration cylindrical shell of dusty gas and influence service life of filter bag, simultaneously for improving the effect of deduster to the dusty gas primary dust removing, promote the rapid landing of bulky grain and cohesion grit, the air inlet of described filtration barrel body is arranged on the bottom of filtration barrel body, near with the junction of ash bucket, and in filtration barrel body, be provided with the whirlwind circle corresponding with the air inlet position, bulky grain in the dusty gas and cohesion grit will fall into ash bucket along the whirlwind circle under the effect of centrifugal force and self gravitation thereof.
The skeleton tube-surface of described support filter bag is zinc-plated or be covered with silicone layer, skeleton tube section ovalize.This skeleton tube-surface is smooth, and the corrosion resistance height is difficult for filter bag is damaged, and structure is more firm, and for filter bag provides bigger coating face, thereby increased filter area.
The fancy top of the suitable for reading and card of the air guide hole of skeleton pipe, filter bag realizes that the traditional approach of sealed engagement is to adopt pressing plate, rubber cushion and bolt and nut to carry out crimping, the implementation process of this scheme is not only taken a lot of work bothersome, sealing effectiveness after the components bonding is also not ideal, and because pressing plate is arranged, bolt and nut is protruding puts on card, cause the winding-up pipe nozzle of turning arm must be far away, be unfavorable for the blowback of winding-up pipe apart from the fancy top of card.The utility model has been banned this juncture, but by the air guide hole at each skeleton pipe circumferential ring expander is set, and makes the fancy top edge sealed engagement by circumferential ring expander and card suitable for reading of each filter bag.Adopt this juncture not only to make implementation process become simple and efficient, and help filter bag and skeleton pipe being carried out maintenance works such as disassembling, assembling and replacing in the future, sealing effectiveness after the components bonding is also better, simultaneously, owing to do not have protruding pressing plate and bolt and nut etc. on the card, make the winding-up pipe nozzle of turning arm be provided with closelyer, thereby the pipe that more helps jetting carry out blowback to the card fancy top from the fancy top of card.
Nozzle place at described winding-up pipe is provided with barricade, and the effect of barricade is to improve the blowback power of blowback air-flow to filter bag, and promotes the blowback air-flow that filter bag bag wall is cleansed.
The beneficial effects of the utility model are: this rotary counter-blowing flat bag deduster is compared with existing pulse bag type dust collector, move more stable, efficiency of dust collection is higher, can make smoke dust discharge concentration far below national regulation, the operation of its reverse gas cleaning device is not subjected to the restriction of use occasion gas source condition, the blowback steady air current is powerful, and dirt is washed in the blowback that can adapt to long filter bag; Simultaneously, it has simple and convenient operation and maintenance, space availability ratio height, takes up an area of advantage little, that the steel consumption is low, and the technology that is specially adapted to fine solid particle reclaims and udst separation.
