[0002] Hydrocatalytic dechlorination is a key reaction technology that selectively removes chlorine atoms from chlorine-containing organic matter and converts them into harmless products through the action of hydrogen and catalyst. It is widely used in chemical industry, environmental protection (such as treatment of chlorine-containing pollutants), preparation of pharmaceutical intermediates and other fields.

[0003] The existing reactor has a single internal heating method, with a significant temperature gradient. Local overheating may cause side reactions, while the low-temperature area will not react completely. The traditional agitator blades are fixed. Although they can drive the raw materials to move in the tank by rotating, they cannot effectively drive the raw materials near the outside (high-temperature area) and the raw materials near the inside (low-temperature area) of the tank to change and adjust, resulting in a significant difference in mixing efficiency between the early and late stages of the reaction, and the overall reaction time is prolonged. To this end, we proposed a hydrogenation catalytic dechlorination reactor. Utility Model Content

[0025] In this embodiment, as the stirring sleeve 5 rotates and cooperates with the fixation of the fixed column 10, the pushing rod 12 will fit the auxiliary pushing groove 11 on the fixed column 10 for adaptation and adjustment. The block 15 on the pushing rod 12 can drive the movable sleeve 7 to adapt and adjust on the fixed rod 6, so that during the rotating stirring operation, the raw materials on the outside can be moved inward, and at the same time, the raw materials on the inside will also move outward with the rotation.
