When the temperature of the flue gas treated by the high-temperature dust bag is too high, the cooling measures such as reducing the operating temperature and releasing the cold air shall be adopted immediately; when the temperature of the flue gas is low, the temperature raising measures such as increasing the operating temperature shall be taken immediately. The temperature of the flue gas can be stabilized within the specified range, ensuring the normal and stable operation of the high-temperature dust bag and reducing the condensation phenomenon. Use in aggressive or explosive conditions should be based on the safety requirements of the first choice of resistance to corrosion. If the space is limited, please use multi-function electromagnetic pulse valve, the temperature of the gas below the dew point temperature must be taken measures. The resistance has the initial resistance and the running resistance of the dust removal accessories. Some of the coarse dust particles fall into the ash hopper due to inertia or natural sedimentation. Most of the rest of the dust particles enter the baghouse as the air flow rises. After being filtered by the filter bag, the dust particles are trapped on the outside of the filter bag and the purified gas From the inside of the filter bag into the upper box, and then from the valve plate hole, exhaust vent into the atmosphere, so as to achieve the purpose of dust.
