Tetrafluorohydrazine lining reaction kettle

Abstract

The present application discloses a tetrafluorohydrazine lining reaction kettle comprising a reaction kettle body, a first tetrafluorohydrazine lining, a second tetrafluorohydrazine lining and a flowblocking assembly. The first tetrafluorohydrazine lining is disposed on the inner wall of the reaction kettle body, the flow blocking assembly is fixed on the inner wall of the reaction kettle body, and the second tetrafluorohydrazine lining is arranged on the flow blocking assembly. By arranging the flow blocking assembly in the reaction kettle body and arranging the second tetrafluorohydrazine lining on the flow blocking assembly, during the stirring, materials continuously collide with the flow blocking assembly, the materials are dispersed evenly, and thus full reaction is performed; the materials in the reaction kettle body are prevented from forming a vortex, a turbulent flow in the reaction kettle body is added, thereby improving overall stability of the reaction kettle body, also improving stirring efficiency and production efficiency, and also reducing the abrasion of the first tetrafluorohydrazine lining in the reaction kettle body after the materials form the vortex.

Description

technical field [0001] The invention relates to the field of chemical production equipment, in particular to a reaction kettle lined with tetrafluoroethylene. Background technique [0002] Reactors in chemical production are generally equipped with stirring devices, and PTFE-lined reactors are no exception. In the actual stirring process, due to the influence of some factors such as the state of the stirred material and the temperature of the stirring, there will be shortcomings such as insufficient stirring uniformity. At the same time, stirring will cause the material to form a vortex in the kettle. When the rotating speed is fast, the material will rise along the cylinder wall to a position much higher than the design liquid level, causing a safety hazard. In addition, there is a PTFE lining in the reaction kettle, and it is easy to cause the PTFE lining in the reaction kettle to be gradually worn out during stirring. When the PTFE lining is severely worn, there will be ...

AI Technical Summary

Problems solved by technology

In the actual stirring process, due to the influence of some factors such as the state of the stirred material and the temperature of the stirring, there will be shortcomings such as insufficient stirring uniformity.

At the same time, stirring will cause the material to form a vortex in the kettle. When the speed is fast, the material will rise along the wall of the cylinder to a position far above the design liquid level, causing a safety hazard.

In addition, there is a PTFE lining in the reaction kettle, and it is easy to cause the PTFE lining in the reaction kettle to be gradually worn out during stirring. When the PTFE lining is severely worn, there will be a great safety hazard, which will cause the equipment to be unsafe and stable. normal operation, resulting in increased production costs
