The working principle of the enamel reactor cover is to form a strong, corrosion-resistant and high-temperature resistant protective layer by coating a layer of enamel glaze on the metal surface. During operation, the medium or material of the chemical reaction is added to the reactor, and the reaction temperature is controlled by heating or cooling operations. The enamel reactor cover tank body is mainly composed of a reaction vessel, a stirring device and a transmission device, a water cooling device, a safety device, etc. Its sealing design is excellent, and a variety of sealing methods are used to ensure safety during the reaction process.
