Welding dust purification equipment instructions dust purification equipment should have a professional operation management, professional staff must be on the equipment performance, operation requirements, safety and maintenance have a more comprehensive understanding of knowledge, and familiar with welding dust purification equipment operation instruction.
Must be installed before driving equipment strict check again.
Item by item, inspection records.
Of driving step 1, run the inspection work before the end, all of the safety measures to be implemented, the relevant personnel to be in position 2, each heater at least 8 h before the start of commissioning, to ensure that the ash hopper and other insulation parts (
Insulating porcelain jacket, electrical porcelain, shaft, etc. )
Dry, to prevent any damage caused by condensation creepage.
Check the current of heater system is normal.
3, the start of induced draft fan.
General flue gas preheating in order to eliminate electrostatic precipitator to the electric field on the internal parts of the moisture, preheating time according to the electric field on the temperature and humidity of the gas, general with the electric field at the end of the outlet temperature of flue gas dew point above.
Pay attention to put out the insulator indoor moisture at this time.
Such as electrostatic precipitator outlet flue gas temperature is lower than the dew point temperature, the high voltage silicon rectifier transformer should not be started.
4, 5 start all vibrating mechanism, to start the various function of low voltage operating system, the alarm and safety interlock, temperature control temperature measurement device, the automatic control operation of the material level detection.
6, to prevent the mixture of putty glue on the plate, pole line and affects the purification equipment operation after welding, welding dust purification equipment should be in boiler combustion completely normal, to remove oil gun, running stable after closed the power switch of high voltage control cabinet.
Then press the start button to start the high-pressure control system functions, waiting for the electric field voltage to flashover point, make the electric field in operation.
