Abstract
The utility model relates to a dust removing purification device, in particular to a downstream pulse bag type dust collector which is adaptable to purifying welding smoke dust and other dry type non-corrosion non-fiber dust. The dust collector comprises a tank body, a dust collecting hopper is arranged on the bottom portion of the tank body, a plurality of vertically arranged cloth bags are disposed on the dust collecting hopper, bottom ends of the cloth bags are communicated with an air collection chamber, the air collection chamber is communicated with an air outlet on the tank body, top ends of the cloth bags are communicated with blow pipes, the blow pipes are connected with an air manifold via a pulse valve, and the tank body is further equipped with an air inlet which is communicated with a space holding the cloth bags. The dust collector utilizes a design of downstream injection, namely airflow enters from the air inlet on the upper portion of the tank body and then is exhausted from the air outlet on the lower portion of the tank body, and the flowing direction of the airflow is consistent with the pulse blowing direction and the direction of dust dropping in the dust collecting hopper, thereby greatly reducing resistance of the dust collector, saving power consumption and being favorable for dust to drop into the dust collecting hopper. The downstream pulse bag type dust collector is high in dust removing efficiency and filtering air speed, and the filter bags thereof are long in service life and stable in running.
Description
Technical field
The utility model is a kind of dust separation device, particularly a kind of suitable pulsed jet cloth filter that purifies weld fumes and other dry type, the non-fibre dust of non-corrosiveness that is applicable to is applicable to the purification of industrial and mining enterprises' dusty gases such as casting sandblast, refractory material, electric furnace smelting, cement building material, grain processing, mine excavation.
Background technology
Sack cleaner is to utilize cloth bag to filter dusty gas.After dusty gas enters deduster, also from top to bottom flow in the outside of cloth bag, pure qi (oxygen) enters cloth bag behind the cloth bag filtration, and dust then is trapped in the cloth bag outside, and cleaned air passes is discharged by the gas outlet by the cloth bag end opening.When the dust of cloth bag surface loading increases, when reaching certain resistance, will have influence on the effect of dedusting, with the passage of time, the mesh on cloth bag surface can be blocked by dust, and deduster is thoroughly paralysed.In order to dredge mesh, to pull down cloth bag and clean with regard to shutting down, this is a job of wasting time and energy.How just can cloth bag be cleaned under non-stop-machine situation, this is a technical problem that urgency is to be solved.
Summary of the invention
The purpose of this utility model is the present situation that must shutdown could clean cloth bag in order to break away from, invents a kind of compressed air to be sprayed into the suitable pulsed jet cloth filter that impels in the cloth bag attached to the dust releasing on cloth bag surface with transonic air-flow.
The purpose of this utility model realizes as follows: described along pulsed jet cloth filter, comprise casing, the bottom of casing is a flue-dust retainer, is provided with a plurality of vertically disposed cloth bags above the flue-dust retainer, and the bottom of cloth bag is communicated with plenum chamber, plenum chamber is communicated with gas outlet on the casing, the top of cloth bag is communicated with the winding-up pipe, and the winding-up pipe is connected with gas bag by pulse valve, and casing is provided with air inlet, air inlet is communicated with the space at cloth bag place, and air inlet is positioned at the top of gas outlet.
Good effect of the present utility model is as follows: the utility model adopts along spray following current design, being air-flow is entered by the air inlet on casing top, discharge from the gas outlet of lower box again, its flow direction and pulse are blown into direction and dust, and to fall into the direction of flue-dust retainer consistent, so just greatly reduce the resistance of deduster, thereby the saving power consumption, and help dust and drop in the flue-dust retainer; The utility model is convenient to assembling and transportation, easy access and replacing cloth bag; The utility model is the novel sack cleaner that a kind of resistance is low, efficiency of dust collection is high, filtration velocity is big, life of bag filter is long, stable.
Description of drawings
Fig. 1 is the utility model structure chart
Among the figure: 1 casing, 2 flue-dust retainers, 3 cloth bags
4 plenum chambers, 5 gas outlets, 6 winding-up pipes
7 pulse valves, 8 gas bags, 9 air inlets
The specific embodiment
As shown in Figure 1, described suitable pulsed jet cloth filter comprises casing 1, and the bottom of casing 1 is a flue-dust retainer 2, be provided with a plurality of vertically disposed cloth bags 3 above the flue-dust retainer 2, the bottom of cloth bag 3 is communicated with plenum chamber 4, and plenum chamber 4 is communicated with gas outlet 5 on the casing 1, and the top of cloth bag 3 is communicated with winding-up pipe 6, winding-up pipe 6 is connected with gas bag 8 by pulse valve 7, casing 1 is provided with air inlet 9, and air inlet 9 is communicated with the space at cloth bag 3 places, and air inlet 9 is positioned at the top of gas outlet 5.。
In concrete the use, after dusty gas enters the deduster casing by the top, from top to bottom flow, behind the cloth bag filtration, dust is trapped in outside the bag again, and cleaned air passes is then come together in the plenum chamber by the cloth bag end opening, discharges from air outlet again.Dust increase when the cloth bag surface loading, when reaching certain resistance, pulse valve is opened, make the compressed air in the gas bag spray an air-flow with transonic speed from the winding-up pipe, thereby induce secondary gas flow to spray into cloth bag together times over this air-flow, cause cloth bag moment sharply to expand, fall into flue-dust retainer thereby make dust attached to the cloth bag outside break away from cloth bag.
Claims (1)
1. one kind along pulsed jet cloth filter, comprise casing, the bottom of casing is a flue-dust retainer, it is characterized in that: be provided with a plurality of vertically disposed cloth bags above the flue-dust retainer, the bottom of cloth bag is communicated with plenum chamber, and plenum chamber is communicated with gas outlet on the casing, the top of cloth bag is communicated with the winding-up pipe, the winding-up pipe is connected with gas bag by pulse valve, and casing is provided with air inlet, and air inlet is communicated with the space at cloth bag place.
