Normal temperature stainless steel reaction kettle is commonly used enamel kettle, that is, the inner wall of the kettle is coated with acid and alkali resistant enamel, which has glass chemical stability and pressure-bearing performance of steel containers. The lining glaze is a kind of glaze composed of silica as the main body and a variety of other elements. After multiple spraying and sintering, it is a kind of enamel coated on the surface of the metal substrate. It can resist various concentrations of organic acid, inorganic acid, Corrosion of organic solvents, weak alkalis and other media, except hydrofluoric acid and strong alkalis.
In the stainless steel reactor, the negative pressure is below 1O1kPa. There is a hole at the bottom of the ferrule, which can be connected to the cold water pipe and can also discharge the excess steam and cooling water in the ferrule. There are 1-2 air holes in the upper part of the jacket, connected to the steam pipe to discharge the cooling water, which can not only make full use of the heat, but also take away the heat released by the reaction, avoid the temperature of the reaction liquid from being too high, and thus can effectively control the exothermic reaction. There is only one exit at the bottom of the ellipse. The dome cover is provided with a feeding port or a manhole (a population hole is opened in a large tank), an observation hole, a sampling hole, a cooling reflux device port, a temperature measuring device port, and a stirrer installation hole.
