The first aid measures for the spray dryer in the event of failure are as follows:
When the effect of the air filter of the spray dryer is poor, it is necessary to improve the air filtration efficiency, clean or replace the filter in time; the coke powder is mixed into the product during production; in this case, it is necessary to check the coke powder at the hot air inlet and adjust the air flow speed, overcome eddy currents, or use a water- or air-cooled jacket around the hot air distributor outlet.
Or the impurity of the material liquid is high, and the material liquid is filtered before spraying because the equipment is not clean and the equipment needs to be cleaned.
If the product powder is too fine in the reproduction process, the product yield is low, and the loss of powder running is large; most of them are due to the low efficiency of the cyclone separator. It is necessary to check whether the cyclone separator is deformed due to knocking, and check the air tightness and internal Whether there is accumulated material or blockage at the outlet. Maybe it's because the bag filter interface is loose or the interface needs to be repaired, and the bag checked and replaced regularly.
If the speed of the centrifugal sprayer is reduced, the current is increased, and the feed rate is too high, overloading it, you need to reduce the amount of feed or mechanical failure of the sprayer and motor; or stop spraying, check and troubleshoot.
If the sprayer speed fluctuates greatly, it is mostly due to the defect of the motor, which causes mechanical resonance between the sprayer and the motor. At this point, the motor should be carefully checked.
