In order to avoid the situation of ultra-low temperature paste bags generated by the high-voltage electrostatic precipitator , the air inlet and the precipitator itself must be insulated and heat-preserved. In addition, when the temperature of the dust is higher than 20 ℃ above the leakage point, the high-voltage electrostatic precipitator  The electric bell will automatically alarm to remind the actual operators to adopt measures to increase the temperature. When the temperature of the smoke and dust is close to the leakage point, the high-voltage electrostatic precipitator will automatically turn off the air supply and the smoke and dust will be converted to the bypass flue duct , The by-pass valve is opened, and the smoke enters the by-pass flue exhaust duct for exhaustion, ensuring that the high-voltage electrostatic precipitator can operate normally.

　　Once the temperature of the dust is higher than the normal application temperature of the high-voltage electrostatic precipitator, the automatic temperature control equipment will start the air-conditioning valve and put in the air-conditioning. In addition, the electric bell will also automatically alarm to remind the actual operating staff to adopt the countermeasures of temperature reduction; When the temperature of the smoke and dust drops to the temperature of all normal applications, the air-conditioning valve will automatically turn off and the actual operation will be restored; after ignoring the air-conditioning, when the temperature of the smoke and dust still exceeds the limit temperature of the dust collector, the electric air valve will be fully automatic When it is turned off, the bypass valve is opened, and the smoke enters the bypass flue for exhaustion, so that the high-voltage electrostatic precipitator can operate normally.
