[0016] Operating Instructions for Special Equipment Used for Maleic Anhydride Recovery and Treatment:

[0017] S1: When performing gas recovery treatment for maleic anhydride recovery, the treatment chamber and the connecting ring are first connected. With the connection plate and the limiting plate connected, the supporting plate and the limiting block provide support for the position of the connecting plate. Then, the gas enters the interior of the connecting chamber and the treatment chamber through the inlet pipe. In the treatment plate, the reaction and purification of the gas causes the particulate matter inside the gas to condense and fall into the collection plate. Under the action of the collection plate and the control ring, the connection of the control rod and the abutment block, and the connection of the abutment block and the connecting groove, the abutment and separation control between the connecting chamber and the treatment chamber are achieved, thus completing the recovery operation of the particulate matter in the collection plate.

[0018] S2: When replacing the processing plate, first separate the connecting compartment and the processing compartment, then pull the pull plate to make the plate slide in the control groove. With the connection of the movable rod and the support rod, change the position of the support rod in the slide groove. Through the connection of the guide rod and the guide groove, change the working length of the support rod, so that the support rod and the fixed block in the processing compartment are separated, and the disassembly operation of the processing plate in the processing compartment is completed.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. By connecting the processing chamber and the control ring, and connecting the connecting chamber and the fixed ring, and through the rotational connection of the control rod and the fixed ring, the angle of the abutment on the connecting groove can be adjusted, thereby achieving the separation effect of the processing chamber and the connecting chamber. This facilitates the pouring operation of particles formed on the collection tray, avoiding repeated reactions between particles and gas, which would affect the gas treatment effect. Under the connection of the connecting ring and the connecting plate, the limiting plate and the support plate complete the support and control effect of the processing chamber.

[0021] 2. By connecting the processing disc and the actuating rod, and with the actuating rod and the control groove connected, and the pull plate and the pull disc connected, the sliding effect of the pull disc in the control groove is achieved. With the connection of the movable rod and the support rod, the position of the support rod in the slide groove is changed. Through the sliding connection of the guide rod and the guide groove, the working length of the support rod is changed, thus completing the separation operation of the processing disc in the processing chamber and achieving the disassembly effect of the processing disc in the processing chamber.
