Abstract
The utility model provides a dust removing device for producing a compound fertilizer. The dust removing device comprises an induced draft fan, a dust settling chamber, a chimney and a cyclone dust collector; the cyclone dust collector is formed by connecting two grades in sequence; an inlet of the induced draft fan is communicated with a dust outlet of a granulating machine, while an outlet of the induced draft fan is communicated with an inlet of the first-grade cyclone dust collector; the outlet of the first cyclone dust collector is communicated with the inlet of the second-grade cyclone dust collector; the outlet of the second-grade cyclone dust collector is communicated with the inlet of the dust settling chamber; and the outlet of the dust settling chamber is communicated with the inlet of the chimney. According to the dust removing device for producing the compound fertilizer, the three-grade dust removing effect is greatly improved, the pollution is effectively reduced, the raw materials are saved, and the production cost is reduced.
Description
Technical field
The utility model belongs to the industrial dedusting apparatus field, is specifically related to a kind of dust arrester that composite fertilizer uses of producing.
Background technology
At present the technique of every country or regional production composite fertilizer mainly contains following several: dry method blending technique, pellet granulation, undertaken by the material of chemically reactive granulation tower granulation, extrusion, liquid compound fertilizer material, the melt pelletization method of non-slurry pelletizing, slurry process granulation, concentrated solution.More than these several production technologies, a granulation stage all produce a large amount of dust at the granule of production process, and the base fertilizer that adopts of granulation is most of is powder raw material, so more dust in producing perplexs enterprise and produces always.Present domestic composite fertilizer manufacturing enterprise generally adopts indoor sedimentation dedusting in composite fertilizer produces, although this process of cleaning is simple and easy, economical, be widely used, but dust removing effects is relatively poor, the air inducing amount is regulated relatively difficulty, and it is outdoor to still have a large amount of dust to be discharged into, and environmental pollution is serious, raw material runs off, and has increased production cost.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is a kind of dust arrester that composite fertilizer uses of producing, and has increased by two cover cyclone dust collectors in this device to improve efficiency of dust collection, alleviates environmental pollution, reduces raw material and runs off, and reduces production costs.
The purpose of this utility model is achieved through the following technical solutions:
A kind ofly produce the dust arrester that composite fertilizer uses; comprise air-introduced machine, dust setting chamber, chimney; the characteristics of this programme are also to comprise cyclone dust collectors; cyclone dust collectors have two-stage series connection to connect; described air-introduced machine entrance is connected with the outlet of comminutor dust; this air-introduced machine outlet is connected with first order cyclone dust collectors entrance; described first order cyclone dust collectors outlet is connected with second level cyclone dust collectors entrance; the cyclone dust collectors outlet of the described second level is connected with described dust settling chamber inlet, and dust setting chamber's outlet is connected with described chimney entrance.
The concrete characteristics of this programme also have, and described second level cyclone dust collectors high and low position is lower than described first order cyclone dust collectors.
The beneficial effects of the utility model are: because this programme has adopted the two stage cyclone duster parallels, the setting of this two stage cyclone deduster can make raw material dust major part reclaim with the dry state form, has reduced raw materials consumption.And air-introduced machine is contained in the middle of comminutor and the cyclone dust collectors, can make the air inducing amount more stable, is more conducive to a dust and is transported to endlessly cyclone dust collectors.In described cyclone dust collectors back the dust setting chamber is set, further residual dust raw material is carried out sedimentation, form 3-stage dust-removal, realized the tail gas qualified discharge, thoroughly solve environmental issue.
Description of drawings
Fig. 1 is the structural representation of dust arrester described in the utility model.
Among the figure: 1 air-introduced machine, 2 first order cyclone dust collectors, 3 second level cyclone dust collectors, 4 dust setting chambers, 5 chimneys.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to accompanying drawing; the utility model comprises air-introduced machine 1; dust setting chamber 4; chimney 5; the characteristics of this programme are also to comprise cyclone dust collectors; cyclone dust collectors have two-stage series connection to connect; described air-introduced machine 1 entrance is connected with the outlet of comminutor dust; this air-introduced machine 1 outlet is connected with first order cyclone dust collectors 2 entrances; described first order cyclone dust collectors 2 outlets are connected with second level cyclone dust collectors 3 entrances; cyclone dust collectors 3 outlets in the described second level are connected with described dust setting chamber 4 entrances, and dust setting chamber's 4 outlets are connected with described chimney 5 entrances.
The concrete characteristics of this programme also have, and described second level cyclone dust collectors 3 high and low positions are lower than described first order cyclone dust collectors 2.
The comminutor dust is delivered to first order cyclone dust collectors 2 by air-introduced machine 1 air inducing; dust carries out centrifugal sedimentation in first order cyclone dust collectors 2; dust enters second level cyclone dust collectors 3 and carries out centrifugal sedimentation afterwards; the dust of a large amount of sedimentations is emitted by cyclone dust collectors lower end drain hole; remaining a small amount of dust enters dust setting chamber 4 together with the mixture of flue gas; the basic sedimentation of residue dust is complete, and the minute quantity dust is discharged by chimney 5 together with flue gas.3-stage dust-removal is realized the tail gas qualified discharge, thoroughly solves environmental issue.
Through improved 3-stage dust-removal effect, be significantly improved and improve with indoor sedimentation dust removing effects before transforming, dust removing effects has improved 30%-40% than originally, effectively alleviated pollution, has saved raw material, has reduced production cost.
Claims (2)
