Multi-stage spray drying tower operation manual and inspection work Multi-stage spray drying tower has small installation site and low price; it can perform automatic cleaning for a short time; it is a non-burning binary hot air heating method; it can change the hot air due to the characteristics of different materials. The diameter of the inlet and outlet pipes and the adjustment of the temperature; the use of cooling cyclone dust collectors to cool the finished products and many other features have been highly evaluated in the market.
Multi-stage spray drying tower operation and inspection work In the daily production process, necessary preparations must be performed before starting a multi-stage spray drying tower. First, check the looseness of the joints between the bearings and the sealing parts of the various devices, and the lubricating oil conditions of the various mechanical parts and whether the respective water, wind, and slurry valve ports are in the desired positions. Then turn on the power to check if the voltage and the meter are normal. Finally, check the amount and concentration of the slurry in the slurry mixing tank. If any problem occurs, remove it in time.
Then turn on the multi-stage spray drying tower blower, exhaust fan, and then turn on the heating switch to start heating. When the outlet temperature reaches the set temperature (usually about 130 °C), start the feed pump and dust removal system. When the pump pressure reached 2 MPa, the spray gun was turned on to start granulation. After the multi-stage spray drying tower is operated, the atomization condition and the material pump working condition should be observed in time. If there is a blocking phenomenon, the nozzle must be cleaned or replaced immediately. At the end of granulation, the heating device should be shut down first to stop the operation of the gas engine. Then close the gun valve, replace the gun, unscrew the nozzle and rinse it clean. When the inlet temperature is reduced below 100°C, the operation of the blower and the exhaust fan can be stopped. Then clean up the remaining materials in the spray drying tower and the dust collector, close the dust collector and air hammer, and finally turn off the main power supply to complete the production operation.
After the normal operation of the multi-stage spray drying tower, it is also necessary to periodically receive the materials and regularly check the operation of each system, record the process parameters, and pay attention to cleaning the vibrating screen.
Multi-stage spray drying tower operation precautions:
In case of emergency, the multi-stage spray drying tower must be shut down immediately. The blower and material pump should be shut down first. If there is a sudden power outage, the gas engine should be pulled out to cool the tower body naturally, then the sewage valve is opened, the slurry in the slurry pipeline is drained, and the equipment is cleaned.
