Precautions for use of boiling dryer

After the normal operation of the boiling dryer, the operation of each system shall be regularly checked, the process parameters shall be recorded, and the vibrating filter screen shall be cleaned For the heater, check whether the tube of the hot boiling dryer is normal If necessary, clean the filter screen at the oil tube, oil pump and oil nozzle If the boiling dryer operates for a long time or due to improper operation, aggregates will appear in some equipment, which will affect normal operation, at this time, it is necessary to stop working for cleaning To ensure that the rate of boiling dryer and less failure of course, pay attention to the daily operation and precautions 1 At the end of granulation, turn off the heating device of boiling granulation dryer and stop the operation of gas turbine Then close the spray gun valve, replace the spray gun, screw off the spray nozzle and wash it 2 Then turn on the forced draft fan and exhaust fan in turn, and then turn on the heating switch to start heating When the outlet temperature reaches the set temperature (generally about 130 ℃), start the feed pump and dust removal system 3 In the daily production process, necessary preparations shall be made before starting the equipment First of all, check whether the connection of bearing and sealing part of each device is loose, whether the lubricating oil condition of each mechanical part and the valve port of each water, air and slurry pipe are in the required position 4 In case of emergency, the equipment must be shut down immediately, and the blower and feed pump shall be shut down first In case of power failure, the gas turbine shall be pulled out to cool the tower naturally, and then the blowdown valve shall be opened to drain the slurry in the slurry pipeline and clean the equipment 5 Then turn on the power supply to check whether the voltage and instrument of the boiling granulation dryer are normal After Zui, check the quantity and concentration of the slurry in the slurry mixing drum If there is any problem, it should be eliminated in time 6 When the inlet temperature drops below 100 ℃, the operation of forced draft fan and exhaust fan can be stopped Then clean up the residual materials in the drying tower and dust remover, close the dust remover and air hammer boiling granulation dryer, after Zui, close the total electric boiling granulation dryer source, and complete the production operation 7 When the pump pressure reaches 2MPa, open the spray gun and start granulating After the operation of the equipment, the atomization condition and the working condition of the material pump of the boiling granulation dryer shall be observed in time If the boiling granulation dryer is blocked, the nozzle shall be cleaned or replaced immediately.
