The inner coil is arranged in the kettle during cooling, the refrigerant directly cools the system through the inner coil, and the heating and cooling mode has the characteristics of simple appearance, compact structure and convenient operation. But exposes a number of serious problems in the production process. Firstly, due to the limitation of the jacket, the contact area between the heating pipe and the oil is limited, the surface temperature of the electric heating pipe reaches hundreds of degrees, the oil is easily carbonized due to local high temperature, the heat conduction oil is deteriorated, the heat conduction efficiency of the heat conduction oil is influenced, and then safety parameters such as flash point and the like are influenced, so the heat conduction oil cannot be continuously used when the heat conduction oil is deteriorated to a certain degree. Secondly, in the cooling process, because the inner coil is arranged, the coil is directly contacted with the system, the leakproofness and the corrosion resistance of the coil are required to be ensured, the coil needs to be pressed and tested to be dense before each use, and the coil can be used only when no electric leakage exists. However, as the service life of the coil pipe is prolonged, the inner cooling medium of the coil pipe enters the reaction kettle system to cause the reaction to be deteriorated if the inner corrosion of the coil pipe is low, and serious safety accidents occur if the inner corrosion of the coil pipe is high.
Disclosure of Invention
In order to solve the problem that temperature measurement exists among the prior art nitration reation kettle, the utility model discloses an electric heating cauldron sets up parts such as electric heating oil stove and oil cooler outside the electric heating cauldron, heats the conduction oil at the cauldron external, then carries the conduction oil after will heating to the system that electric heating cauldron presss from both sides the cover in to electric heating cauldron and heaies up, reduces the temperature that gets into the conduction oil through the oil cooler, and then adjusts the heating temperature in the electric heating cauldron.
