Description

Detachable salt bath jacket of reaction kettle Technical Field The utility model relates to a detachable salt bath jacket suitable for an experimental device reaction kettle, and belongs to the technical field of chemical heat exchange. Background The reaction kettle is in an important reactor form of a chemical test device, the heating mode can be an electric furnace or a heating sleeve for directly heating the outer wall of the reaction kettle, or a salt bath jacket is arranged outside the reaction kettle, and the electric furnace is used for heating the salt bath jacket to indirectly heat the reaction kettle. The electric furnace is adopted for direct heating, and the strong radiation heat of the electric furnace wire at high temperature is easy to coke the materials contacting the inner wall in the reaction kettle, although the electric furnace wire is simple in form and convenient to process. Especially for the easily coked materials such as coal tar, kerosene slurry, petroleum residual oil and the like, the phenomenon of in-situ coking in the reaction kettle occurs in the high-temperature test process. The salt bath jacket is arranged outside the reaction kettle, and the high-temperature molten salt is used for heating the wall of the reaction kettle, so that the influence of strong radiant heat of a heater can be avoided, and the coking tendency of test materials is greatly relieved. However, for high-temperature and high-pressure reaction kettles, a salt bath jacket is directly welded on the reaction kettle body, equipment manufacturers worry about unpredictable damage to the reaction kettle body caused by welding operation, the pressure resistance of the reaction kettle is affected, and danger occurs in the use process. Therefore, development of a detachable salt bath jacket which does not need to be welded with the reaction kettle is very necessary to ensure the safe use of the reaction kettle under severe conditions. Disclosure of Invention The utility model aims to solve the technical problem of providing a detachable salt bath jacket suitable for a reaction kettle of a test device. In order to solve the problems, the utility model provides a detachable reaction kettle salt bath jacket, which comprises a salt bath jacket arranged outside a reaction kettle, wherein a salt bath heater is arranged outside the salt bath jacket, a quick-opening flange is arranged at the top of the salt bath jacket, the inner edge of the quick-opening flange is limited at a supporting boss of the outer edge of the reaction kettle, a quick-opening flange outer edge inner return hook is arranged at the outer edge of the quick-opening flange, an outwards extending salt bath jacket top outward extending edge is arranged at the top of the salt bath jacket, and the quick-opening flange outer edge inner return hook extends to the bottom of the salt bath jacket top outward extending edge. Preferably, the width of the supporting boss is 1-2mm. The distance between the support boss and the body flange of the reaction kettle is as small as possible, but the quick-opening flange is ensured to be convenient to install. Preferably, the distance between the inner wall of the salt bath jacket and the outer wall of the reaction kettle is 20-50mm.
