The utility model has reasonable method. The device keeps the advantages of the traditional equipment and has the characteristics of simple structure, low equipment cost and low maintenance workload.

Description

A kind of pre-dedusting device
Technical field
The utility model relates to a kind of pre-dedusting device, belongs to the udst separation technical field.
Background technology
In industrial production, having bad luck of raw material and finished product all can produce a large amount of dust in fragmentation and the production process.For the protection environment reduces the raw material loss, the dust cleaning system is essential.For the higher place of some dust content, only use the one-level sack cleaner too big to the cloth bag load, frequent deashing also can cause damage to cloth bag.We need be provided with a cover pre-dedusting device before sack cleaner, most crude particle dust is disposed.The simple structure of the present cyclone dust collectors of using always, cost of equipment is low, and maintenance workload is few, uses more extensive.But rise because cyclone duster structure causes dusty gas to touch the end at the ash bucket place, carry the isolated dust of part and discharge, dust removing effects is not good.
Summary of the invention
The purpose of this utility model is, a kind of pre-dedusting device is provided, so that original cyclone dust collectors are carried out structural adjustment and optimization, can avoid air-flow that the dust that has separated in the flue-dust retainer is rolled again and taken away as far as possible, thereby improve dust removing effects and overcome the deficiencies in the prior art.
The technical solution of the utility model: a kind of pre-dedusting device of the present utility model comprises the cylindrical shell of the top cylindrical shell, conical shell, circular cylinder body and the flue-dust retainer formation that set gradually from top to bottom; The tangential direction of top cylindrical shell is provided with smoke inlet, and the top of top cylindrical shell is provided with exhanst gas outlet; Be provided with radiation shield in the cylindrical shell, cinder-discharging port is arranged at the flue-dust retainer bottom.
In the aforesaid pre-dedusting device, described exhanst gas outlet inserts the top inner barrel, and the nadir of exhanst gas outlet is lower than the minimum point of smoke inlet.
In the aforesaid pre-dedusting device, the awl tube that described radiation shield is, the bottom of radiation shield is provided with the dust passage between radiation shield and the circular cylinder body between circular cylinder body.
In the aforesaid pre-dedusting device, described radiation shield top is provided with air-vent.
In the aforesaid pre-dedusting device, described radiation shield is fixedlyed connected with cylinder inboard wall through support bar.
Owing to adopted technique scheme, compared with prior art, the utility model can efficiently be handled dusty gas, and the dust of avoiding secondary gas flow to have separated is rolled again and taken away, and can improve the udst separation effect.Method of the present utility model is reasonable, and used device has kept the advantage of existing equipment, has simple structure, and cost of equipment is low, the characteristics that maintenance workload is few.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-smoke inlet, 2-exhanst gas outlet, 3-top cylindrical shell, 4-conical shell, 5-circular cylinder body, 6-flue-dust retainer, 7-cinder-discharging port, 8-radiation shield, 9-air-vent, 10-dust passage, 11-support bar.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment of the present utility model: structural representation of the present utility model as shown in Figure 1, device of the present utility model comprises the cylindrical shell that the top cylindrical shell 3 that sets gradually, conical shell 4, circular cylinder body 5 and flue-dust retainer 6 constitute from top to bottom; The tangential direction of top cylindrical shell 3 is provided with smoke inlet 1, and the top of top cylindrical shell 3 is provided with exhanst gas outlet 2; Exhanst gas outlet 2 inserts cylindrical shell 3 inside, top, and the nadir of exhanst gas outlet 2 is lower than the minimum point of smoke inlet 1.Be provided with radiation shield 8 in the cylindrical shell, radiation shield 8 is fixedlyed connected with cylinder inboard wall through support bar 11.The awl tube that radiation shield 8 is, the bottom of radiation shield 8 are provided with the dust path 10 between radiation shield 8 and the circular cylinder body 5 between circular cylinder body 5.Cinder-discharging port 7 is arranged at flue-dust retainer 6 bottoms.Radiation shield 8 tops are provided with air-vent 9.
The employed method of the utility model is that dusty gas is entered pre-dedusting device by the smoke inlet of top cylindrical shell along tangent line; Because dust slips into flue-dust retainer and discharges by ash discharging hole along rotatablely move dust passage between radiation shield and circular cylinder body of cylinder inboard wall in the centrifugal force that air-flow rotation is produced, air-flow; Enter the most of upwards reflection of air-flow of cylindrical shell, only have a small amount of gas to enter flue-dust retainer, can prevent that the dust that secondary air will separate from rolling again and being pulled away, thereby improve dust removing effects with grit.The exhanst gas outlet of described pre-dedusting device stretches into inner barrel, and the nadir of exhanst gas outlet is lower than the minimum point of smoke inlet, avoids dust-contained airflow directly to discharge from exhanst gas outlet.Described radiation shield top is provided with air-vent, and a small amount of gas that enters flue-dust retainer can be discharged by air-vent.
Operation principle of the present utility model is as follows:
Dusty gas tangentially enters pre-duster and rotation moves downward.Because dust will be close to cylinder inboard wall and slip in the centrifugal action, air-flow.After dust-contained airflow entered conical shell, because cylindrical shell enlarges, air velocity significantly reduced, and air-flow is reflected and moves upward after screen stops, the air communication after the processing is crossed outlet and discharged.Dust in the air-flow enters flue-dust retainer by the dust passage between radiation shield and cylindrical shell and discharges by cinder-discharging port.On a small quantity the air-vent of gas by the radiation shield top that enters in the flue-dust retainer through the dust passage enters cylindrical shell.Can effectively dust in the flue-dust retainer and air-flow be separated by radiation shield, the dust of avoiding secondary gas flow to have separated is rolled again and is taken away, thereby has improved the udst separation effect.
Device of the present utility model can insert dust separation system as required and use.When having relatively high expectations as purification, can add sack cleaner behind this device, this device uses as pre-duster.
