Temperature range of enamel reaction kettle

enamel reaction kettleThe operating temperature isBelow 200 degrees Celsius. Because the enamel layer is sintered on the surface of the enamel reaction kettle, and the enamel layer will melt when it exceeds 200 degrees Celsius, the temperature of the material inside the kettle is not allowed to exceed 200 degrees Celsius.

Do not suddenly heat during the high-temperature quenching process to avoid damaging the surface of the enamel reaction vessel glass lining. The heating or condensing speed should be maintained at approximately3 minutes, should not exceed 5 minutes. When the low temperature is less than or equal to 0, the water stored in the conduit rack should be drained after use to avoid damaging the equipment due to freezing. The temperature resistance of the reaction kettle changes rapidly, with a difference of 100 between the temperature of the enamel reaction kettle during thermal shock and the temperature of the heating or condensing medium, and 90 during cold shock. In order to adapt to the corrosiveness of various solutions, enamel reaction vessels are sometimes lined with various materials such as lead lining, porcelain tile lining, and even the pot body is made of steel or cast iron. Increasing the heat transfer area per unit volume can increase the heat load. Compared to the jacket, the coil can be placed in the kettle, but it is inconvenient to install and clean the coil. It can be installed when needed. Open the steam or condensate inlet valve. It cannot be opened at once. The jacket should be introduced in advance until the pressure reaches around 0.1 MPa. After a few minutes, slowly open the inlet valve to prevent the equipment from being damaged by thermal shock. When introducing steam heating, the water in the jacket should be drained first.

Open type glass lined reactor(Open enamel reaction kettle) is a composite material product made by uniformly spraying enamel glaze containing high silica on the inner surface of a steel reaction kettle container, and then firmly adhering it to the metal surface through a reasonable high-temperature burning process (professional term: enamel equipment enamel burning process). The lid and body of the open glass lined reaction kettle can be separated, and a sealing gasket is placed between the lid and body and fixed around it with a clamp. This series of glass lined reaction vessels is easy to use, maintain, and repair. It has the dual advantages of glass stability and metal strength, and is an excellent corrosion-resistant chemical equipment with reliable performance such as corrosion resistance, impact resistance, smoothness and aesthetics, insulation and heat resistance, pressure resistance, and easy cleaning. Open type glass lined reaction vessels are widely used in industrial production processes such as chemical, petroleum, pharmaceutical, pesticide, food, dye, etc. They are ideal equipment for hydrolysis, neutralization, crystallization, mixing, emulsification, etc.

The reaction temperature of the enamel reaction kettle isAt 160 ℃, the jacket of the reaction kettle is filled with steam at a pressure of 6-7 kilograms. At this point, it suddenly switches to cooling water at 10 ℃, with a temperature difference exceeding 150 ℃. If the temperature difference is too large, the enamel reaction kettle is prone to bursting and will be finished after a few uses. At this point, you need to set up a hot water tank. For example, first use 80 ℃ water to cool the material to around 100 ℃, and then switch to 10 ℃ cooling water. This can greatly increase the service life of the enamel reaction kettle.
