Description
Technical field
The utility model belongs to dedusting technology field in chemical fertilizer production, specifically, relates to a kind of pipeline dust purging system for cyclone dust removal.
Background technology
In fertilizer industry, dust arrester application is quite general, particularly in the products such as production composite fertilizer, phosphorus ammonium, in dry, granulation process, can produce a large amount of dust, remove dust the most frequently used be to utilize blower fan for power source, by cyclone dust collectors or sack cleaner, carry out dedusting.But problem of this dedusting method ubiquity---pipeline dust accumulation problem.Because pipeline angle of inclination is too small, conveyance conduit is long or air current flow speed is excessively slow, and the gravitational settling effect of dust self, cause part dust granules to be deposited in pipeline, therefore or pipeline relatively mild position long at dead angle, the pipeline of channel bend place, pipeline very easily produces the phenomenon that dust accumulation even causes line clogging, as dust stratification is not cleared up in time, can get more and more, cause pipe ventilated area to reduce, resistance increment, affects flowing of air-flow; When serious, cause obstruction, affect the operation of upstream and downstream equipment, so that cause production accident.
Particularly in production composite fertilizer, because kind is numerous, operating temperature is inconsistent, it is low that the aridity of dust also has height to have, once temperature is slightly low, dust is also easy to the caking that makes moist, and being workman, the processing mode for the treatment of this situation just needs at set intervals to beat dredging pipeline or on pipeline, open cleaning eye, parking is cleared up, and has so just delayed a large amount of time, causes inefficiency.
Utility model content
For solving above technical problem, the purpose of this utility model is to provide a kind of pipeline dust purging system for cyclone dust removal, can effectively be dried and the interior dust of accumulating of purging system pipeline, prevents the accumulation of dust, thus the obstruction of prevention pipeline.
The utility model object is achieved in that a kind of pipeline dust purging system for cyclone dust removal, its key is: comprise one-level whirlwind, secondary whirlwind and blower fan, described one-level whirlwind, secondary whirlwind and blower fan are connected successively by connecting pipe, the air inlet pipe of described one-level whirlwind is provided with electric heater, the outlet pipe of described blower fan is communicated with dust blow device, this dust blow device comprises purging house steward and at least 2 purging arms, described purging house steward is communicated with the outlet pipe of blower fan, described purging arm one end is communicated with described purging house steward, the other end is communicated with described connecting pipe.
Adopt said structure, the high wind of cyclic utilization system blower fan accesses purging arm by purging house steward, purges arm connecting pipe is purged, and the place of easy sedimentating dust in connecting pipe is dried and purges cleaning, can also prevent the accumulation of dust, thus the obstruction of prevention connecting pipe.
Above-mentioned purging arm is communicated with the front and back section of horizontal segment, bending place or close this bending place of described connecting pipe.
Due to horizontal segment, bending place sedimentating dust very easily, therefore adopt said structure, can effectively process targetedly the problem of dust accumulation in connecting pipe.
Being provided with at least 2 and being the connecting branch of α angle with this connecting pipe of above-mentioned connecting pipe, this α angle is acute angle and the direction of gas flow in described connecting pipe dorsad, described connecting branch is positioned at the front and back section of horizontal segment, bending place or close this bending place of described connecting pipe, and this connecting branch is communicated with described purging arm.
Adopt said structure, connecting branch can purge along the direction of gas flow in connecting pipe, reduces to purge resistance, can also work in coordination with mobile gas and together the dust of piling up be purged, and has improved the efficiency purging.
The diameter of above-mentioned connecting branch is less than the radius of described connecting pipe.
Adopt said structure, the wind-force that the connecting branch that diameter is little produces is stronger, can effectively purge the dust in connecting pipe.
Above-mentioned one-level whirlwind is comprised of a primary cyclone, and described secondary whirlwind is composed in parallel by two secondary cyclones.
Above-mentioned purging house steward is provided with master control valve, and described purging arm is provided with branch line control valve.
Adopt said structure, the whole running of controlling dust blow device of master control valve energy, branch line control valve can be controlled the purging of everywhere, easy to use.
Beneficial effect:
A kind of pipeline dust purging system for cyclone dust removal of the utility model, can effectively be dried and the interior dust of accumulating of purging system pipeline, prevent the accumulation of dust, thereby the obstruction of prevention pipeline, and simple and practical, purge simple and fast, without parking, greatly reduce workman's labour intensity, and improve greatly equipment driving rate.
