Description

A kind of bag-type dust collector
Technical field
The invention discloses a kind of bag-type dust collectors, are related to environmental protecting device design field.
Background technique
Bag filter is mostly used to be filtered to the processing of dusty gas at present, its working principle is that passing through connecting tube Dusty gas is introduced into the cabinet of bag filter by road, and dusty gas is moved by the graviational interaction of air-introduced machine to cloth bag, powder Dirt is attracted on cloth bag, and cleaned gas is discharged out of cloth bag, to achieve the effect that air cleaning.But because existing Bag filter gas connection pipe is directly connected on the upside of the middle cabinet of bag filter, enters the intracorporal ash-laden gas of case Body air-introduced machine under the action of can flow velocity become larger, pour the cabinet of bag filter at a high speed under the action of inertia force, into Cartonning intracorporal high speed dusty gas part is discharged directly through after cloth bag from upper box gas discharge outlet, another part dust-laden Gas declines after impacting cloth bag from cabinet air inlet side, is then arranged by gas after Bag filter from the gas discharge outlet of upper box Out.It is very strong to the scouring force of cloth bag windward side due to entering the intracorporal dusty gas of case at a high speed, cause cloth bag windward side can not Stick dust, and a large amount of dust is gathered in the leeward of cloth bag.The leeward dust absorption that will lead to deduster in this way is blocked up, Gas can not pass through, and necessarily will increase blowback frequency in this way;Windward side is then because of good permeability, and strong adsorption force, tiny grit can be straight It connects and is discharged into atmosphere across cloth bag.The purification efficiency and efficiency of dust collection for leading to existing bag filter can not improve.It is wherein above-mentioned to lack Be trapped in flue gas dry cleaning processing system show it is the most obvious, because need in flue gas dry cleaning processing system will be in flue gas Pernicious gas carry out adsorption cleaning using adsorbent, adsorbent is generally all kinds of dust, and the adsorbent of addition needs to recycle benefit With being for these reasons unevenly distributed the adsorbent on cloth bag, it is just directly logical that part pernicious gas is not exposed to adsorbent Cloth bag enters air-purifying chamber, and the gas permeability of the catharsis being not achieved, windward side is preferable, the little particle absorption that need to partially recycle Agent also passes through cloth bag and enters air-purifying chamber, and recovery efficiency is low.
Summary of the invention
The present invention solves the technical problem of: in use for conventional cloth bag deduster, dusty gas is straight It connects and washes away cloth bag, cloth bag is caused to damage, and low efficiency during blowback, need multiple blowback, cause the higher problem of energy consumption, provide A kind of bag-type dust collector.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that:
A kind of bag-type dust collector, including dust collector box body, dust collector box body outside the top are equipped with air outlet, air outlet Lower section is equipped with air inlet, and dust collector box body lower half is equipped with ash bucket, and hopper bottom is equipped with discharge port, and dust collector box body passes through bottom The support frame of portion's installation is fixed on ground, and the top is equipped with back-blowing device inside dust collector box body, and back-blowing device is located at cloth bag Top, it is characterised in that: be equipped with helical blade inside cloth bag, and be equipped with inside dust collector box body in cloth bag installation site side Baffle is evenly distributed with baffle fan blade on baffle;
When using the bag-type dust collector, dusty gas enters dust collector box body by air inlet, in airflow function Under, equally distributed baffle fan blade rotation above baffle is driven, dusty gas is avoided directly to impact to cloth bag and cloth bag is caused to damage It is bad, while larger particles are directly fallen into ash bucket, under the action of negative pressure by the later dusty gas of baffle, are passed through cloth bag, are made Gas and dust are separated in cloth bag surface, and filtered clean gas was being used by being discharged after cloth bag through air outlet Cheng Zhong drives the helical blade in cloth bag to rotate, and generate when cloth bag surface dust accumulation thickness reaches 2~4mm by back-blowing device Centrifugal force makes cloth bag surface dust accumulation fall into ash bucket, and the dust in ash bucket is discharged through discharge port.
The helical blade is fixed on inside cloth bag using central axis, and central axis is free to rotate.
The baffle surface is evenly distributed with baffle fan blade, and baffle fan blade is fixed in baffle circular hole by bearing, and Baffle fan blade can 360 ° be freely rotated.
The baffle fan blade material therefor is 304 stainless steel plates with a thickness of 2~4mm.
The back-blowing device uses compressed air for gas source, and compressed air pressure is 0.6~0.8MPa.
Material used in the helical blade is 302B stainless steel.
The beneficial effects of the present invention are:
(1) bag filter that the present invention develops in use, is made using the buffering of the baffle with baffle fan blade With slowing down the dusty gas into bag filter directly to the percussion of cloth bag, can effectively avoid dusty gas to cloth bag Directly wash away caused by cloth bag be lost, reduce maintenance of equipment frequency, effectively reduce manpower and material resources;
(2) the bag filter blowback that the present invention develops is high-efficient, during blowback, drives cloth bag using purge gas The helical blade of middle installation rotates, and generates centrifugal force, reaches the efficient removing to cloth bag all angles dust accumulation, and have benefited from baffle The interception function of fan blade can make most crude particle fall directly into ash bucket, and excessive coarse granule is avoided to be adsorbed in cloth bag surface, influence Blowback effect can be such that cloth bag surface dust accumulation falls into ash bucket, save energy consumption without multiple blowback in use, tool Have broad application prospects.
