Abstract

The invention provides a dust removal and purification device for the drying process of a fluidized bed and relates to the technical field of dust removal and purification. The dust removal and purification device comprises a fluidized bed dryer, wherein a dust collection hood is arranged at the upper part of the fluidized bed dryer, and a dust removal pipeline is arranged at the upper part of the dust collection hood; a double-cylinder cyclone dust collector is arranged on the right side of the dust removal pipeline, and a bag-type dust collector is arranged on the right side of the double-cylinder cyclone dust collector; a fan is arranged on the right side of the bag-type dust collector, and a spray tower is arranged on the right side of the fan; a stuffing layer is arranged in the spray tower, and a chimney is arranged at the upper part of the spray tower. The dust removal and purification device has the advantages of simple structure, good purification effect and environmental protection, and dust concentration can be greatly reduced to reduce influence on crops around the fluidized bed. When dusty gas passes through the spray tower, fine dust is further captured so that emission on standard is realized, and the effect is significant.

Description

Fluid bed baking operation dedusting and purifying device
Technical field
The present invention relates to udst separation technical field, be specifically related to fluid bed baking operation dedusting and purifying device.
Background technology
Fluid bed is that a large amount of solid particles are suspended among the fluid of motion, thereby makes particle have some appearance features of fluid, and the solid contact condition of this stream is called fluidization of solid.Our company need to make the production line of a purified treatment soluble glyphosate pulvis, and annual production is 1000T.The dust and the ammonia that while wherein feeding in raw material mixing, produce are larger, and fluid bed produces a large amount of dust while drying, and dry in discharging opening and screening process and produce a large amount of dust at fluid bed.The dust producing due to this production technology has the stronger water-disintegrable faintly acid that is simultaneously, the growth of plant is had to stronger inhibitory action, and dust has certain corrosivity, in order further to reduce dust emission concentration, the impact of minimizing on surrounding enviroment, therefore this part dust and gas cleaning must thoroughly, be worked the mischief to avoid cumulative effect.
Summary of the invention
Technical problem to be solved by this invention is to provide the dedusting and purifying device of a kind of simple in structure, good purification and protection of the environment, i.e. fluid bed baking operation dedusting and purifying device.
Technical problem to be solved by this invention realizes by the following technical solutions:
Fluid bed baking operation dedusting and purifying device, comprise fluid bed dryer, described fluid bed dryer top is provided with dust shield, dust shield top is provided with cleaning shaft, cleaning shaft right side is provided with double-cylinder cyclone dust extractor, double-cylinder cyclone dust extractor right side is provided with sack cleaner, double-cylinder cyclone dust extractor is connected by pipeline with sack cleaner, sack cleaner right side is provided with blower fan, sack cleaner is connected with blower and pipeline, blower fan right side is provided with spray column, spray column inside is provided with the filling bed of material, spray column top is provided with chimney, the surrounding on spray column top is provided with water inlet pipe, the bottom on spray column right side is provided with outlet pipe.Double-cylinder cyclone dust extractor adopts side air intake mode, makes dust-contained airflow reduce local dusty gas concentration evenly to arrive filter bag surface compared with low velocity, improves filter efficiency, and can extend life of bag filter.
Described sack cleaner bottom is provided with ash bucket, and ash bucket has 2, and ash bucket angle is 50 °~65 °.Ash bucket adopts two ash buckets, and ash bucket angle design is for convenience of blanking.Because dust has certain adhesiveness, at ash bucket one side installing pressure-air big gun, rely on high-voltage pulse airstream vibration smooth and easy to guarantee dust underflow, and adopt star device for discharging automatic ash-discharging.
Described water inlet pipe is evenly distributed on spray column top, and water inlet pipe has 6; Described chimney height is 14m~15m.In order further to reduce dust emission concentration, reduce the impact on surrounding enviroment, now design a spray column, blower fan exhaust outlet is connected to spray column.When dusty gas passes through spray column, fine solid particle is further trapped, qualified discharge.
The invention has the beneficial effects as follows: the present invention has advantages of simple in structure, good purification and protection of the environment, can greatly reduce dust concentration, reduce the impact of crops around; when dusty gas passes through spray column; fine solid particle is further trapped, qualified discharge, and effect is remarkable.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
