Chemical common sense: How do you know the maintenance and working principle of the reactor?

A variety of various equipments in chemical equipment, as the protagonist of chemical reaction vessels, reactor, it is a comprehensive reaction vessel, has been widely used in petroleum, chemical, rubber, pesticides, dyes, medicine, food, A pressure vessel used to complete processes such as sulfurization, nitration, hydrogenation, alkylation, polymerization, condensation, etc., such as reactors, reaction vessels, decomposition kettles, polymerization kettles, etc.; materials generally include carbon-manganese steel, stainless steel, zirconium, and nickel-based ( Hastelloy, Monel, Inconel alloys and other composite materials.

During the operation of the reaction kettle, the product materials may be polymerized, stirred, mixed, etc., and the temperature, pressure, speed, product reaction characteristics, etc. in the reaction process should be highly controlled, and the user selects the equipment. At the time of the model, we must also understand the product characteristics requirements and equipment specifications, and also carry out maintenance and precautions in the production process to avoid the existence of hidden dangers.

Reactor maintenance:

1. It should be operated strictly according to the working pressure and working temperature marked on the product nameplate to avoid danger.

2. Strictly observe the regulations on cooling and oil filling in the product manual, and do a good job in maintenance and maintenance of the equipment.

3. When all valves are used, the valve stem (needle) should be rotated slowly to close the cover to achieve the sealing effect. It is not easy to use excessive force when closing, so as not to damage the sealing surface.

4. The electrical control instrument shall be operated by a special person and the overload protection facilities shall be set as required.

working principle:

The reaction vessel is placed in the inner layer to carry out a stirring reaction, and the interlayer can be heated or cooled by a different cold heat source (refrigerant, hot water or hot oil). The constant temperature (high temperature or low temperature) hot-dissolving medium or cooling medium is injected through the reaction vessel interlayer, and the materials in the reaction kettle are heated or cooled at a constant temperature. At the same time, the stirring reaction can be carried out under normal pressure or under negative pressure according to the use requirements. The material is reacted in the reaction vessel, and the evaporation and reflux of the reaction solution can be controlled. After the reaction is completed, the material can be discharged from the discharge port of the bottom of the kettle.
