The structural characteristics of the glass lined porcelain enamelled half pipe jacket reactor and the principle of half pipe forming: the middle part of the half pipe jacket is the kettle body, the kettle body is surrounded by half pipes longitudinally and the half pipes are equipped with circulating cooling water, the cross section of the half pipes is semi-circular, the porcelain enamelled reactor body and the surrounding half pipes are welded together. The raw material used for the half-pipe is sheet metal. The sheet is then passed through several sets of forming rollers (concave and convex wheels) in straight rows at the front and rear. The rotation of the concave and convex wheels drives the sheet forward, followed by a transverse bending to form a semi-circle, followed by a longitudinal bending to form a ring.

Glass lined reactor half pipe jacket design points to note.

1, the design should pay attention to ensure the circulation cross-sectional area of the circulating medium in the half-pipe jacket and its thermal conductivity or insulation performance.

2, in order to avoid the jacket steam or other media pollution of the outer wall at the entrance of the vessel, it is necessary to design an anti-punching plate, which is welded to the outer wall of the vessel and is facing the entrance of the jacket media.

3, in order to make the jacket space is full of media, it is necessary to exclude the jacket space all the gas, which needs to be designed in the jacket top a diameter of not less than 10mm exhaust hole, and the more is in the jacket top its exhaust effect is better.

4, do a good job of flaw detection and heat treatment: If the medium in the porcelain-lined reactor is highly hazardous medium or extremely hazardous medium, do a good job of 100% ray flaw detection, and then carry out the heat treatment work after the welding of the closure and the container; for the heat treatment requirements to complete the welding of the closure and the container and then carry out the heat treatment work.

Advantages of half-tube jacketed glass-lined reactor.

In terms of heat exchange, the ordinary standard jacketed glass lined reactor can get a larger heat exchange area, but the flow rate in the jacket is slow and the heat transfer system is low, while the half-tube jacketed glass lined reactor has a slightly smaller heat exchange area, but the flow rate is fast and the heat transfer system is high.
