Abstract

The utility model relates to an inclined folding bag dry-method dust remover for a pulse device, which can rotate and vibrate; the dust remover belongs to a connection net device which is slantingly arranged in a dust-containing warehouse, connected by a folding circular bag dust cylinder, a rotary vibration device and a combination-typed piston nozzle, and composed of multi-row staggered chains. The dust remover has the structure function of automatic rotation, vibration and blowback, and can quickly remove the dust which is absorbed on the bag; the method of using the clean gas as the blowback dust removal carrier is favorable for the application in the dust removal of the furnace gas. The dust remover can carry out dust removal processing to the dust-containing air with the dust-containing concentration of more than 40g/m <3> and enables the dust-containing concentration to be reduced below 20mg/m <3>. The dust remover is not only applicable to the processing of the dust-containing gas in various furnace gas industries, but also applicable to the processing of the dust-containing gas in the industries like processing, mining, light industry and so on.

Description

The oblique collapsible sack cleaner of whirling vibration pulse

Affiliated technical field

The utility model relates to a kind of oblique collapsible cloth bag nonaqueous dust cleaner with rotation, vibration, pulser.Be applicable to the dust removal process of the dusty gas of all kinds of kiln coal gas, also be applicable to the dust removal process of the dusty gas of industries such as metallurgy, machinery, mine, light textile and materials processing.

Background technology

At present, the cloth bag nonaqueous dust cleaner that uses is the cloth bag of vertical straight shape, its effective dedusting face is effective, the general employing divided the storehouse blowback, vibration is finished by machinery or electromagnetic pulse etc., and produce certain negative pressure to the nozzle place at the cloth sack, too the blowback efficiency of dust collection is low with air quantity, influences the discharge of Purge gas; And volume is bigger, and maintenance is inconvenient.

Summary of the invention

Deficiencies such as existing sack cleaner volume is big, effectively the dedusting area is little, blowback efficient is low in order to overcome, maintenance inconvenience.The collapsible sack cleaner that the utility model provides a kind of separate unit to be combined into, this deduster can not only carry out dedusting by collapsible round bag-type dust tube, but also the blowback dust pelletizing system that has unique time rotation, vibration, carries out synchronously.

The technical scheme that its technical problem that solves the utility model adopts is: be connected with the whirligig of interior chamfered indentations wheel construction (6) with the similar collapsible round bag-type dust tube end opening place of accordion structure, suitable for readingly be connected, and be seated in the dust-laden storehouse with the form of constant slope with built-up piston nozzle (7).1 gear is equipped with in the lower end on the every fulcrum of dedusting tube of upper and lower layer (Fig. 2) outside the dedusting warehouse, 3～4 gears are housed on the every fulcrum in intermediate layer, forms a synchronous transmission web frame network (Fig. 3) thus; The upper end outlet is carried out closed blowback Purge gas control by piston type nozzle to single group dedusting tube in the Purge gas storehouse; Use the matching structure design of sprocket wheel and interior oblique serrated wheel, make the rotation of dedusting tube, vibration reach the effect of carrying out synchronously.The beneficial effects of the utility model are, volume is little, efficiency of dust collection is high, simple in structure, easy to maintenance.Quote clean gas in the cleaning position as blowback dedusting gas, the application in more helping aspect the dedusting of kiln coal gas.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1. be process principle figure of the present utility model.

Fig. 2. be (A-A) generalized section that cloth bag is arranged among Fig. 1.

Fig. 3. be that rotating mechanism is arranged schematic diagram (sprocket wheel layout schematic diagram).

1. flue dust cooler, 2. whirlwind gravitational precipitator, 3. dust-laden storehouse, 4. collapsible cloth bag, 5. cleaning position, 6. tiltedly serrated wheel, 7. closed type piston nozzle, the 8. clear dirt of blowback system, 9. unloading valve in the whirling vibration, 10. slanting baffle, 11. chains, 12 sprocket wheels, 13. handle dusty gases.

The specific embodiment

In Fig. 1, flue dust cooler (1) mainly is at handling high-temperature smoke gas (13), when processed gas enters whirlwind gravitational precipitator (2), can be to dust content 40g/m by whirlwind gravitational precipitator (2) ³Above dusty gas is by this kind dust removal process method; The gas that contains fine particles enters dust-laden storehouse (3), and the dust removal process of the oblique collapsible cloth bag (4) by having functions such as rotation, vibration, pulse can drop to 20mg/m with dust content again ³Below, the Purge gas after the processing enters cleaning position (5) and discharges.

By motor drives chain (11), what the sprocket wheel (12) of chain (11) and each dust removing units was formed an orderly layering is connected net (Fig. 3), interconnect rotation, tiltedly serrated wheel (6) rotation in driven rotary vibration when connecting axle rotates, make folding bag-type dust tube rotation and produce displacement upwards on the sawtooth inclined-plane, compression spring during displacement is when moving to certain position, effect by compression rear spring power makes the laying up bag dust collector produce unexpected falling, thereby has produced the effect of vibration; When oblique collapsible cloth bag (4) tube is installed, be set to different setting angles respectively, the sawtooth inclined-plane is rotated on different angle faces simultaneously, thereby produced the function of timesharing vibration.

When rotating to the position of setting, system opens blowback gauge tap (being that the clear dirt of blowback system (8) opens the bi-bit bi-pass control valve) automatically, Purge gas after the compression enters closed type piston nozzle (7) earlier conical lid is pushed to before, Compressed Gas be blown into purification in collapsible cloth bag (4) when sealing collapsible cloth bag (4) exhaust outlet after makes the attached long-pending dust of collapsible cloth bag (4) outer surface be subjected to vibration and blowback wind action and coming off; Locating (except the upper strata) above collapsible cloth bag tube is provided with the dust that comes off above the suitable dust block board (see figure 2) and is lived by slanting baffle (10) shelves, dust group can not directly drop to collapsible cloth bag (4) and get on, and drop at the bottom of the storehouse, the dust at the bottom of the storehouse enters dust compartment by unloading valve (9).
