⑶大盖及出口短节安装；大盖结合面装好密封垫，用斜铁紧固好。如果斜铁槽有

(3) Installation of the large cover and the outlet sub-section; install the gasket on the joint surface of the large cover, and fasten it with an inclined iron. <br>If there is open welding or cracks in the inclined iron groove, electric welding should be used to repair the welding, and the inclined iron shall be reinstalled. <br>⑷Adjustment of the pulse solenoid valve; the solenoid valve action interval is normal, every 30 seconds, the pressure is adjusted to 0.4MPa. The <br>differential pressure device is reinstalled. <br>⑸Close the manhole door; replace the sealing ring of the manhole door again. If the top rod is open or deformed, weld it with electric welding and repair it. It is firm and firm without leakage <br>. Reinstallation; the purge and vibration air source tank is fixed and reliable, and there is no leakage at the inlet and outlet joints.

(3) installation of large cover and outlet nipple; Install the sealing gasket on the joint surface of the large cover and fasten it with inclined iron.<br>If there is open welding or crack in the inclined iron groove, repair welding with electric welding and reinstall the inclined iron.<br>(4) adjustment of pulse solenoid valve; The action interval of solenoid valve is normal. It acts every 30 seconds and the pressure is adjusted to 0.4MPa<br>Reinstall the differential pressure device.<br>(5) sealing of manhole door; The sealing ring of manhole door shall be replaced again. If there is open welding or deformation of the pole, it shall be welded by electric welding and repaired, firm and free of leakage<br>(6) purging and rapping of bag filter and reinstallation of air source tank; The purging and rapping air source tank shall be fixed reliably, and the inlet and outlet joints shall be free of leakage.

(3) Installation of big cover and outlet nipple; Install the gasket on the joint surface of the big cover and fasten it with inclined iron. If there is an open weld or crack in the inclined iron trough, repair welding with electric welding and install the inclined iron back. ⑶ Adjustment of pulse solenoid valve; The solenoid valve operates at normal intervals every 30 seconds, and the pressure is adjusted to 0.4MPa. Installation of differential pressure device. 5] Closure of manhole door; Replace the sealing ring of manhole again. If there is open welding or deformation of the stem, weld it with electric welding, repair it, be firm and firm without leakage. [6] Reinstallation of purge and vibration air source tank of bag filter; The purge gas source tank is fixed reliably, and there is no leakage at the inlet and outlet joints.
