Abstract
The invention relates to an air-flow grading unit dust recovery device. The air-flow grading unit dust recovery device comprises a grader, a cyclone separator, and a bag-type dust collector which are connected by an induced draught fan and a pipeline; hopper opening of the grader is provided with a double-layer pneumatic valve; and the cyclone separator and the bag-type dust collector are connected with a charging barrel via a butterfly valve respectively. The air-flow grading unit dust recovery device is characterized in that outlet of the induced draught fan is connected with bag-type dedusting equipment. Beneficial effects of the air-flow grading unit dust recovery device are that: packaging workshop dust obtained in catalytic cracking catalyst preparation processes can be processed and recycled; and energy is saved, cost is reduced, environment is protected, and influences of dust on health of surrounding people are reduced.
Description
Technical field
The invention belongs to oil-refining chemical catalyst preparation field, relate in particular to a kind of air current classifying unit device for recovering powder.
Background technology
The unit of Catalyst Production is divided into raw material plastic, spray shaping, roasting, washing, filtration, pneumatic conveying drying, air current classifying rewinding etc.Catalyst mixes after plastic in raw material plastic unit, spray-dried unit carries out drying and moulding, finished product after moulding (particle diameter 100 microns in powder) is attracted to enter air current classifying rewinding unit through pipeline by blower fan, blower fan mouth place dust carries out direct emptying process, finished product is flowed in barrel (DN300) by air current classifying feed opening, a lot of dust of can kicking up in the process falling at finished product.And this element is mainly hand-filling, even if workman has on anti-dust respirator, also can a lot of dust of inspiration, dust can cause poisoning to human body, or causes various pneumoconiosis.Dust also makes illuminance and visibility reduce, and affects the visual field of office operation.Applicant had once done some transformations with regard to above-mentioned technical problem.Refer to accompanying drawing 2, a pipeline of frame (DN50-80) above grader, then at the feed opening place of grader 1, cyclone separator 2, sack cleaner 3, draw lower three minutes pipelines (DN35-45), the mouth of pipe flushes (instant packed) with feed opening, and in the porch of blower fan, adds a butterfly valve control air force.By improving, the dust of packing shop reduces, but the dust of collecting has all been discharged in air.Dust emission in atmosphere again severe contamination atmospheric environment, harm periphery population health.Dust can also absorb solar ultraviolet shortwave part in a large number, has a strong impact on growing of children.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, and a kind of air current classifying unit device for recovering powder is provided, and after the dust of packing shop is reclaimed by sack cleaner, the more anti-plastic unit of throwing into reuses.
The present invention for achieving the above object, be achieved through the following technical solutions, a kind of air current classifying unit device for recovering powder, comprise that grader, cyclone separator and sack cleaner are connected with pipeline by air-introduced machine, described grader hopper port is provided with double-layer pneumatic valve, on described cyclone separator and sack cleaner, by butterfly valve, be connected with barrel respectively, it is characterized in that: described air-introduced machine outlet is connected with bag-type dust equipment.
Described bag-type dust equipment comprises deduster body, several filter bags, compressed air gas bag, filter chamber and ash bucket, described deduster body forms integral body by filter chamber with the ash bucket that filter chamber below is connected, several filter bags are radially set in described filter chamber, described filter bag upper opening is communicated with compressed air air flue, and described compressed air air flue is connected with the compressed air gas bag that is placed in deduster body outside.
The filter chamber top of described deduster body is provided with the air-purifying chamber being communicated with it, and described air-purifying chamber is provided with the exhaust duct with atmosphere UNICOM.
On described compressed air gas bag, be connected with magnetic valve.
Beneficial effect: packing shop dust in catalytic cracking catalyst preparation process is processed to recycling.Dust is recycled, reached the object of energy-conservation, consumption reduction, protection of the environment.Reduced the impact of dust on periphery population health.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of air current classifying unit before transformation.
In figure: 1, grader, 2, cyclone separator, 3, sack cleaner, 4, air-introduced machine, 5, double-layer pneumatic valve, 6, butterfly valve, 7, barrel, 8, the filter bag under filtration condition, 9, compressed air gas bag, 10, magnetic valve, 11, air-purifying chamber, 12, the filter bag under deashing state, 13, filter chamber, 14, ash bucket, 15, pipeline, 16, bag-type dust equipment, 17, deduster body, 18, compressed air air flue, 19, exhaust duct.
The specific embodiment
Below in conjunction with preferred embodiment, to according to the specific embodiment provided by the invention, details are as follows: refer to accompanying drawing, a kind of air current classifying unit device for recovering powder, comprise that grader 1, cyclone separator 2 and sack cleaner 3 are connected with pipeline 15 by air-introduced machine 4, described grader hopper port is provided with double-layer pneumatic valve 5, on described cyclone separator and sack cleaner, be connected with barrel 7 respectively by butterfly valve 6, described air-introduced machine outlet is connected with bag-type dust equipment 16.Described bag-type dust equipment comprises deduster body 17, several filter bags 8,12, compressed air gas bag 9, filter chamber 13 and ash bucket 14, described deduster body forms integral body by filter chamber with the ash bucket that filter chamber below is connected, several filter bags are radially set in described filter chamber, described filter bag upper opening is communicated with compressed air air flue 18, and described compressed air air flue is connected with the compressed air gas bag that is placed in deduster body outside.The filter chamber top of described deduster body is provided with the air-purifying chamber 11 being communicated with it, and described air-purifying chamber is provided with the exhaust duct 19 with atmosphere UNICOM.On described compressed air gas bag, be connected with magnetic valve 10.
The course of work: the dusty gas that air-introduced machine is taken out is incorporated in bag-type dust equipment, with the gas of dust, by the filter bag 8 under the filtration condition in filter chamber 13, the filter bag under adsorbing powder dust, deashing state 12 is carried out to become clean gas after removing dust and clearing ash and enter in atmosphere, the dust under filter reclaims through exporting 14.Flue dust is inhaled in filter chamber by conduit, enters uniformly after the casing at sack cleaner middle part, is adsorbed on filter bag in appearance, and dusty gas enters air-purifying chamber after filter bag filters, and through exhaust duct, enters atmosphere.When resistance of the filter bag reaches limit value, deashing device is opened electric control pulse valve by pressure reduction program and is carried out pulse jet, and now compressed air is shaken off the dust of filter bag surface attachment, through ash bucket, falls discharge.
The above, be only preferred embodiment of the present invention, not structure of the present invention done to any pro forma restriction.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical scheme of the present invention.
