Key points to pay attention to in the design of the half pipe jacket of the glass lined reaction kettle:
1. When designing, attention should be paid to ensuring the cross-sectional area of the circulating medium inside the half pipe jacket and its thermal conductivity or insulation performance;
2. In order to avoid contamination of the outer wall of the inlet of the container by jacket steam or other media, it is necessary to design an anti impact plate, which is welded to the outer wall of the container and directly faces the inlet of the jacket media.
3. In order to fill the jacket space with medium, it is necessary to exhaust all gases in the jacket space. This requires designing an exhaust hole with a diameter of no less than 10mm at the top of the jacket, and the more it is located at the top of the jacket, the better the exhaust effect.
4. Do a good job in flaw detection and heat treatment: If the medium inside the enamel reactor is a highly hazardous or extremely hazardous medium, 100% radiographic testing should be carried out, and then heat treatment work should be carried out after welding the closed parts and containers; For those with heat treatment requirements, the heat treatment work should be carried out after completing the welding work of the closure and container.
Advantages of half tube jacket glass lined reaction kettle:
In terms of heat exchange, ordinary standard jacket glass lined reaction kettles can obtain a larger heat exchange area, but the flow speed inside the jacket is slow and the heat transfer system is low, while half tube jacket glass lined reaction kettles have a slightly smaller heat exchange area, but the flow speed is fast and the heat exchange system is high.
