Abstract
The utility model relates to a dryer de-dusting system. The de-dusting system comprises a fan connected with a dryer outlet, a cyclone dust extractor connected with a fan outlet, a buffer setting chamber connected with a cyclone dust extractor, and an electric dust extractor connected with a buffer setting chamber outlet, wherein the outlet of the electric dust extractor is equipped with a dust choking frame on which a stainless steel separating screen is arranged, and the mesh aperture of the stainless steel separating screen is 0.5-0.6 mm. The de-dusting system provided by the utility model can greatly improve the de-dusting effect through the four-stage de-dusting of the cyclone dust extractor, the buffer setting chamber, the electric dust extractor and the stainless steel separating screen, the dust concentration entering the electric dust extractor is obviously lower than the standard design value, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of dryer auxiliary device, more particularly, relates to a kind of dryer dust pelletizing system.
Background technology
In the chemical fertilizer preparation process, need to adopt dryer that the finished product or the semi-finished product that make in the process are dried.In the drying course, will inevitably produce some dust.These dust enter into the next link of the manufacturing, can affect the product quality of next link.
Existing method is to export give a dinner for a visitor from afar machine and electric cleaner at dryer, by blower fan dust is sucked first, then enters into the electric cleaner dedusting.Usually the dedusting standard of electric cleaner is that the requirement dust concentration is less than 40g/m3, but enter at present dust concentration in the electric cleaner greater than 80g/m3, in the situation that dust content significantly exceeds standard, " corona blocking " phenomenon appears in electric field pole easily, and affect dust removing effects, the simultaneously greatly brief service life of electric cleaner.
The utility model content
For overcoming the defective of above-mentioned prior art, the utility model proposes a kind of new dryer dust pelletizing system, its good dedusting effect, and do not affect service life of electric cleaner.
Dryer dust pelletizing system of the present utility model, comprise the blower fan that is connected with the dryer outlet, the cyclone dust collectors that are connected with described fan outlet, the buffering expansion chamber that is connected with described cyclone dust collectors outlet, export the electric cleaner that is connected with described buffering expansion chamber, the dust flow blocking rack is equipped with in the exit of described electric cleaner, be provided with the stainless steel filter on the described dust flow blocking rack, the mesh aperture of described stainless steel filter is 0.5～0.6mm.
In dryer dust pelletizing system described in the utility model, the bottom of described cyclone dust collectors and buffering expansion chamber is provided with the removing dust and clearing ash mouth.
Adopt dryer dust pelletizing system of the present utility model, has following beneficial effect: carried out the level Four dedusting by cyclone dust collectors, buffering expansion chamber, electric cleaner, stainless steel filter, can greatly improve dust removing effects, the dust concentration that enters electric cleaner also is starkly lower than the standard design value, obtains its service life prolonging.
Description of drawings
Fig. 1 is the designs simplification figure of dryer dust pelletizing system of the present utility model.
The specific embodiment
The utility model relates to a kind of dryer dust pelletizing system of 3-stage dust-removal, as shown in Figure 1, comprises blower fan 2, cyclone dust collectors 3, buffering expansion chamber 4, electric cleaner 5, dust flow blocking rack 6, stainless steel filter 7.
Wherein, 1 outlet of the entrance of blower fan 2 and dryer is connected, is 110g/m3 through the dust concentration of blower fan 2 compressions and acceleration.The outlet of blower fan 2 is connected with the entrance of cyclone dust collectors 3, and cyclone dust collectors 3 are as the first order treating apparatus of dedusting, mainly processes particle diameter greater than 10 microns dust.The bottom of cyclone dust collectors 3 offers the removing dust and clearing ash mouth, is used for regularly removing handled dust.
The outlet of cyclone dust collectors 3 is connected with buffering expansion chamber 4, and as second level dust treatment plant, the precipitation of utilizing flue dust gravity is carried out the sedimentation second time to the flue dust of greater particle size.Equally, for making things convenient for deashing, buffering expansion chamber 4 bottoms also offer the dust cleaning door.
Electric cleaner 5 is connected with the outlet of buffering expansion chamber 4, two-stage dedusting through the front, the dust concentration that enters electric cleaner 5 entrances obviously reduces, there is original 110g/m3 to be down to 38g/m3 once, reach in the standard design value scope of electric cleaner 5, can not produce a little dizzy inaccessible phenomenon, its use state and greatly being taken on a new look service life.
Further, in electric cleaner 5 outlets dust flow blocking rack 6 is housed also, the stainless steel filter 7 that stretched tight on this dust flow blocking rack 6, dust can be blocked through behind this stainless steel filter 7, thereby further improves dust removing effects.The aperture of preferred stainless steel filter 7 is between 0.5～0.6mm, and 3-stage dust-removal does not have the dust of processing before being used for intercepting.
Adopt the large dryer dust pelletizing system of the utility model, carried out the level Four dedusting by cyclone dust collectors, buffering expansion chamber, electric cleaner, stainless steel filter, can greatly improve dust removing effects, the dust concentration that enters electric cleaner also is starkly lower than the standard design value, obtains its service life prolonging.
Specific embodiment described herein only is to the explanation for example of the present invention's spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, and these are revised, replenish and substitute and all belong within the scope that the utility model protects.
Claims (2)
1. dryer dust pelletizing system, it is characterized in that, comprise the blower fan that is connected with the dryer outlet, the cyclone dust collectors that are connected with described fan outlet, the buffering expansion chamber that is connected with described cyclone dust collectors outlet, export the electric cleaner that is connected with described buffering expansion chamber, the dust flow blocking rack is equipped with in the exit of described electric cleaner, be provided with the stainless steel filter on the described dust flow blocking rack, the mesh aperture of described stainless steel filter is 0.5～0.6mm.
2. dryer dust pelletizing system according to claim 1 is characterized in that, the bottom of described cyclone dust collectors and buffering expansion chamber is provided with the removing dust and clearing ash mouth.
