Description

A kind of rewinding dust arrester
Technical field
The utility model relates to a kind of rewinding dust arrester.
Background technology
Sack cleaner is the general dust arrester of current Application comparison.Sack cleaner type is named according to purge mode mostly, mainly be divided into mechanical oscillation type sack cleaner, air blowback type sack cleaner and pulse jet type sack cleaner three kinds, have the thin dirt of sub-micron particle diameter large compared with the scope of high grade dust-collection efficiency process gas flow.
Purposes: the granule dust in separation industries waste gas and fine solid particle, is widely used in metallurgy, mine, cement, steam power plant, building materials, casting, chemical industry, tobacco, asphalt mixture machine, grain, machining, boiler dusting.Dusty gas is entered by air inlet, and when ash flue bucket, in gas, part big dust particle is separated by inertia force and Action of Gravity Field, directly falls into hopper bottom.Dusty gas is by entering the sock filtration district of raising middle flask body after ash bucket, gas is through filter bag, and dust is delayed at filter bag outer surface, and purified gas enters after upper box through filter pocket mouths, then is discharged by air outlet.Along with the prolongation of filtration time, the dust layer on filter bag is constantly long-pending thick, and the resistance of cleaner constantly rises, and when equipment resistance rises to setting value, deashing device starts to carry out deashing.First, a locellus lift valve cuts out, filtered airflow is blocked, then electromagnetic impulse valve is opened, compressed air, with extremely very brief time undergoes rapid expansion in upper box, pours in filter bag, makes filter bag dilatancy produce vibration, and under the effect of washing away at inverted draft, the dust be attached on filter bag outer surface is stripped and falls into ash bucket.After deashing, electromagnetic impulse valve is closed, and lift valve is opened, and filtration condition is recovered again in this room.The each room of deashing is carried out successively, starts to be a cleaning cycle to deashing next time from the first Room deashing.Fall into ash bucket through the dust filtered and deashing work is retained down, then concentrate discharge by the ash-discharging device of grey quarrel.
Operation principle: deduster is made up of parts such as ash bucket, upper box, middle casing, lower boxes, and upper, middle and lower casing is chamber structure.During work, dusty gas enters ash bucket by air inlet duct, and thick grit directly falls into hopper bottom, dustshot with air-flow turnover upwards enter in, lower box, dust is long-pending is attached to filter bag outer surface, and the gas after filtration enters upper box to pure qi (oxygen) concetrated pipe ~ exhausting duct, drains into air through exhaust blower.Deashing process is the pure qi (oxygen) outlet conduits first cutting off this room, the state (locellus blowing-out deashing) making the cloth bag of this room be in airless to pass through.Then unbalanced pulse valve compressed air carries out pulse jetting deashing, the stop valve shut-in time is enough to ensure that the dust settling peeled off from filter bag after winding-up is to ash bucket, avoid dust behind disengaging filter bag surface again with the phenomenon of the attached collection of air-flow to adjacent filter bag surface, make filter bag ash removal thorough, and by program controller PLC instrument, Automatic Control is carried out to air bleeding valve, pulse valve and unloading valve etc.
Present stage, the research of people to dust arrester is a lot of, most dust arrester is after dedusting operation a period of time, dust removing effects progressively reduces, design one needs manually to clear up dust-removal cloth-bag, adds heating power work, so can reach dustproof function, again can the operation of Automatic clearance dust-removal cloth-bag after filtering surface blockage problem long afterwards, reduce manpower work dust arrester extremely urgent.
The pertinent literature that we find is as follows:
1. Chinese Patent Application No. is: 20139428500.0, denomination of invention: sack cleaner, summary: the invention provides a kind of sack cleaner, comprise casing, upper level board, lower horizontal board, the cavity of casing is divided into three air chambers by two level boards, air chamber is divided into inlet plenum, filter air chamber and discharge chamber from bottom to up, be connected with out ash bucket bottom described inlet plenum, go out outside ash bucket and be provided with vibrating device, go out ash bucket and be communicated with inlet plenum, inlet plenum side is provided with air inlet pipe, and air inlet pipe is provided with valve; Described filter air chamber is provided with multiple cloth bag, and the blind end of cloth bag is fixedly connected with by silk rope with upper level board, and cloth bag is provided with wire, and wire is wrapped in outside cloth bag; Lower horizontal board is provided with the air inlet identical with cloth bag number, and the openend of described air inlet and cloth bag is fixed, and described upper level board is provided with gas outlet, and described discharge chamber is provided with escape pipe.Structure of the present invention is simple, easy to use, solves the problem of ash hole blocking.Shortcoming is: after deduster uses a period of time, is accumulated in the fine dusts cleaning difficulty on dust-removal cloth-bag, causes the dust removing effects of dust-removal cloth-bag not good.
2. Chinese Patent Application No. is: 20119242711.6, denomination of invention: sack cleaner and fan combination unit, summary: the present invention relates to a kind of bag-type dust collecting equipment, particularly a kind of sack cleaner and fan combination unit.Sack cleaner and blower fan are the present invention includes, also include airduct, described sack cleaner includes housing, housing is provided with deduster air inlet and deduster air outlet, blower fan is provided with air inlet and fan outlet, deduster air inlet is directly connected with outside dust sucting pipeline, and deduster air outlet is connected with air inlet by airduct, and fan outlet is connected with outside atmosphere.Structure of the present invention is simple, environmental protection, and service life of fan is long, and sack cleaner is convenient to dismounting transport, and cost of transportation is low.Shortcoming is: after this device long-play, and the fine dusts cleaning difficulty accumulated in sack cleaner, reduce efficiency of dust collection, dust removing effects is not good.
3. Chinese Patent Application No. is: 201190107057.4, denomination of invention: cleaner and dust arrester thereof, summary: the invention discloses a kind of dust arrester, its box house is provided with deduster, the side of deduster is provided with blast pipe, and opposite side is provided with discharge pipe; Box house is also provided with blower fan, is connected with air main between the air inlet of blower fan and discharge pipe; The exhaust outlet of blower fan is connected with the exhaust duct be connected with extraneous air.In use procedure, the air-flow that blower fan drives makes the inside of deduster form vacuum environment, make the air with impurity under atmospheric pressure effect, be entered the inside of dust arrester by blast pipe, pure air after deduster filters drains in extraneous air through the internal pipeline of dust arrester, and whole processing procedure treatment effeciency is higher.In addition, the invention also discloses a kind of cleaner applying above-mentioned dust arrester, its dust treatment effeciency is higher, and processing procedure more thoroughly effectively.Shortcoming is: after this device long-play, and the fine dusts cleaning difficulty accumulated in sack cleaner, reduce efficiency of dust collection, dust removing effects is not good.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of structure simple, easy to operate, good dedusting effect, the rewinding dust arrester that efficiency of dust collection is high.
The technical solution of the utility model is achieved in that
