[0002] According to the published patent CN219518333U, a recycling device for N-methylpyrrolidone organic waste gas is described. A gas filtration mechanism is installed on the waste gas recycling pipeline, which is connected to a waste heat recovery mechanism. The waste heat recovery mechanism is connected to a gas condensation mechanism via a gas transition pipeline. The gas filtration mechanism removes particulate matter and other impurities from the waste gas, improving the efficiency of N-methylpyrrolidone recycling. - The recovery quality of methylpyrrolidone is good, but the following shortcomings still exist;

[0016] 1. This utility model incorporates a flow-limiting plate. To adjust the flow rate of the exhaust gas, a knob can be turned clockwise. The knob rotates the worm gear, which in turn rotates the worm wheel. The worm wheel then rotates the rotating sleeve, which in turn rotates several protruding rods around it. These protruding rods then cause the slide rail to swing, which in turn causes the shaft block to rotate. The shaft block then rotates the rotating rod, which in turn causes the flow-limiting plate to rotate. This allows for free adjustment of the exhaust gas flow rate during the recycling process, ensuring that the exhaust gas can be accepted into the subsequent recycling process at a suitable flow rate, thus preventing the exhaust gas flow rate from being too fast and affecting the recycling efficiency.

[0017] 2. This utility model incorporates a filter plate. To replace the filter plate, turn knob two counterclockwise. Knob two rotates worm gear two, which in turn rotates worm wheel two, which in turn rotates gear two. Gear two then rotates gear two, which in turn moves several racks, which in turn move the clips. All the clips disengage from the mounting slots, thus no longer restricting the filter plate's movement. The filter plate can then be pulled out of the mounting slot. A new filter plate can be installed by reversing the steps described above. This design effectively filters exhaust gas to remove particles and impurities, preventing impurities from being recycled along with the exhaust gas. Furthermore, it allows for quick and easy replacement of the filter plate after prolonged use.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
