Short pipe supporting type jacket structure reaction kettle

Abstract

The invention belongs to the field of chemical industry production device and particularly relates to a short pipe supporting type jacket structure reaction kettle. A jacket is arranged on the surface of a reaction kettle body and the surface of a conical head. A through hole is formed in the cellular jacket, and a reinforcing sleeve connected to the surface of the reaction kettle body is fixed in the through hole. According to the short pipe supporting type jacket structure reaction kettle, the pressure bearing capacity of the reaction kettle body and the jacket can be enhanced, the wall thickness of the reaction kettle body is reduced, and improvement of the heat transfer effect is facilitated. Meanwhile, the reinforcing sleeve can constantly change the flow direction and the flow velocity of fluid in the jacket, so that turbulence is formed and an original laminar flow layer is damaged or thinned, and therefore cold and heat exchange is accelerated and the heat transfer effect between the fluid in the jacket and the interior of the kettle body is greatly enhanced.

Description

technical field [0001] The invention belongs to the field of chemical production equipment, in particular to a reaction kettle with a short tube supporting jacket structure. Background technique [0002] At present, the heating, heat preservation and stirring reactors commonly used in the chemical, food, and pharmaceutical industries are all jacketed or semicircular tube structures. For equipment with larger diameters, the inner cylinder body has to withstand a certain amount of pressure under the action of external pressure. Rigidity, in the case of not being unstable, it is necessary to increase the thickness of the inner cylinder shell, which will increase the material cost of the equipment. The semicircular pipe jacket structure is all welded with half pipe joints, and the welding workload is large. In addition, the cylinder body When it is thin, it is prone to welding deformation and quality problems. Contents of the invention [0003] Aiming at the deficiencies of t...
