Deduster can be multiple stage, and multiple stage duster parallels uses together.
Powder material of the present invention and liquid material mixing apparatus work like this: close blow-off valve and charging valve, open intake valve, starts blower fan, in effect downstream high-speed circulating flowing in circulation canal of blower fan; Open charging valve and add powder, powder forms fluidisation state and high-speed circulating flowing in circulating line under the effect of high velocity air; Start atomizer and add liquid material, the powder Quick uniform of the liquid material and fluidisation state that are dispersed into particulate mixes, heat and exchange of moisture is carried out rapidly between high degree of dispersion compound in the gas flow and gas, moisture in compound is vaporized, the air-flow separated with deduster is discharged through deduster exhaust outlet, and compound obtains drying; After drying completes, open blow-off valve, compound is discharged through blow-off valve along with air-flow.
In order to increase heating load, on circulation line II, heater can be installed.
Powder material of the present invention and liquid material mixing apparatus form circulation canal by blower fan, circulation line I, deduster, control valve, air inlet threeway, circulation line II, powder material is added by charging valve, liquid material is added by atomizer, under the airflow function that blower fan produces, powder material and liquid material complete and mix and drying in circulation canal, the air-flow that moisture is separated with deduster is discharged, and device structure is simple, easy to operate, rate of drying is fast.
