Reaction Kettle Quickly get high temperature method of operation
High temperature Reaction Kettle in the chemical, chemical reaction needs to work under high temperature conditions, for different Reaction Kettle performance structure heating method also has water heating, hot steam heating, other media heating, electric heating and other options.
1, water heating: the temperature is not high when used, the heating system is divided into open and closed two. Open the most simple, it consists of circulating pump, sink, pipe and control valve regulator composed of high pressure water, the mechanical strength requirements of the device, Reaction Kettle surface welding of the snake, snake and kettle wall gap, resulting in Reaction Kettle increases the heat resistance and reduces the heat transfer effect.
2, hot steam heating: Reaction Kettle heating temperature below 100 ℃, the following can be used to heat a steam or less; 100 ~ 180 ℃ range with saturated steam; when Reaction Kettle higher temperature, you can use high pressure superheated steam.
3, Reaction Kettle heating with other media: If the process requires Reaction Kettle must be operated at high temperatures, or to avoid the use of high-pressure heating system, other media can be used instead of water and steam, such as mineral oil (275 ~ 300 ℃) (Boiling point: 258 ° C), molten salt (140 to 540 ° C), liquid lead (melting point 327 ° C), and the like.
4, the new Reaction Kettle electric heating: the resistance wire wrapped in the reaction Kettle cylinder insulation layer, or installed in the reaction Kettle distance from the ad hoc insulator, so the resistance wire and Reaction Kettle kettle body formed between the Large space gap. The use of the first three methods to obtain high temperature are required in the kettle body on the additional jacket, due to the magnitude of the temperature change, so that the kettle jacket and shell to withstand temperature changes in temperature and stress. The use of electric heating, equipment, light and easy, easy to adjust the temperature, while not pumps, stoves, chimneys and other facilities.
 Reaction Kettle is a container for physical or chemical reactions. By the kettle body, kettle cover, jacket, stirrer, transmission, shaft seal device, support and other components. Stirring form generally has anchor type, paddle type, turbo type, push type or frame type. The cooling method for the jacket cooling and the reaction Kettle coil cooling, stirring the form of the blade and so on. Bearing seat with a support or ear-type bearings and so on. Speed more than 160 rpm should use gear reducer.
Let's take a closer look at how to operate Reaction Kettle:
1, before use Check Reaction with the Reaction Kettle pipes and valves, to ensure compliance with the conditions of the material, before feeding.
2, check the mixing motor, reducer, machine seal, etc. are normal, reducer oil level is appropriate, machine cooling water supply is normal.
3, to ensure that no abnormal circumstances, start stirring, according to the provisions of the amount of material into the material. More than 10m3 Reaction Kettle or stir the bearing under the reaction Kettle is strictly prohibited air operation, to ensure that the bottom bearing immersed in the liquid surface, before opening the mixing.
4, strict implementation of the operating procedures, pay close attention to Reaction Kettle temperature and pressure and Reaction Kettle jacket pressure, is strictly prohibited over-temperature and overpressure.
5, the reaction process, should be done touring inspection, found that the problem should be dealt with in a timely manner.
6, if the phenomenon of over-temperature, immediately water cooling. The temperature after cooling should be in accordance with the Reaction Kettle process requirements.
7, if the phenomenon of overpressure, should immediately open the vent valve emergency pressure relief.
8, in case of power outages, should stop feeding, open the vent valve, water cooling. And the Reaction Kettle residual liquid clean, close the bottom valve, feed valve, into the valve, discharge valve and so on.
