Advantage of the present utility model and having the beneficial effects that: provide a kind of spray dryer, it is possible to by cyclone separator
The dust that tail gas is carried secretly reclaims, and improves product yield, environmental protection and energy saving.
The work process of spray dryer of the present utility model is as follows:
Compound zirconium hydroxide serosity in slurry can sends into spray drying tower by serosity input pipe, and hot blast input pipe is to spray
Mist drying tower input hot blast, compound zirconium hydroxide forms fine particle after hot air drying, and with hot-air by the first pipeline
Enter cyclone separator and carry out solid and gas separation, major part granule after cyclone separator separates from cyclone separator bottom discharge
Mouth discharging.The tail gas of cyclone separator enters in spray column by second pipe, opens infusion pump and the second control on the 3rd pipeline
Valve processed, cuts out the 3rd control valve, by infusion pump, spray column tower bottom liquid body is squeezed into spray equipment, carries the tail gas of dust with spray
Drenching liquid to be fully contacted in spray column, dust granules weight increases, and enters at the bottom of spray column tower with ejecting liquid, and tail gas is by spray
The gas outlet drenching tower discharges.After reclaiming after a while, in spray column tower bottom liquid body, the content of powder increases, and closes the 3rd
The second control valve on pipeline, opens the 3rd control valve on the 4th pipeline, and spray column tower bottom liquid body is defeated by the 4th pipeline
Delivering to filter in pressure filter, the filter cake obtained enters subsequent processing, and the filtrate obtained is squeezed into and is continuing with at the bottom of spray column tower.
Tail gas in second pipe can carry out heat exchange, to heat by the gas not heated in heat exchanger and hot blast input pipe
Gas in wind input pipe preheats, and improves efficiency, reduces energy consumption.
On hot blast input pipe, medium effeciency filter is set, the cold air of aerator input can be filtered, prevent spraying
In drying tower, material is contaminated.
Gas-liquid separation device is set in spray column, gas liquid separating function can be played, improve product yield further.
