The chemical reaction of stainless steel reactor usually needs to be carried out under certain temperature conditions, so the reactor is subject to both pressure and temperature. Stainless steel reaction kettle to obtain high temperature is usually the following methods:

Steam heating temperature, available below one atmosphere to heat the steam; range, with saturated steam; when the temperature is higher, high pressure superheated steam water heating requirements can be used when the temperature is not high, the heating system has an open and closed two types. Open type is relatively simple, it consists of circulating pumps, tanks, pipelines and control valves regulator is composed of when the use of high-pressure water, the mechanical strength of the equipment requires high reaction kettle welded on the outer surface of the snake tube, snake tube and kettle wall has a gap, so that the thermal resistance to increase the effect of heat transfer is reduced.

Electric heating will be wound in the kettle cylinder resistance wire insulation, or installed in the kettle from the ad hoc insulator a number of distances from the kettle, with other media heating process requirements must be operated at high temperatures or want to avoid the use of high-pressure heating system, other media can be used instead of water and steam, such as mineral oil diphenyl ether mixtures, molten salts, liquid lead, and so on. As a result, a small space gap is formed between the resistance wire and the reactor body.

The first three methods to obtain high temperatures are required in the kettle body with additional jackets, due to large temperature changes, so that the reactor jacket and shell to withstand temperature changes and temperature difference pressure. When using electric heating, the equipment is lighter and simpler, the temperature is easier to adjust, and no pumps, furnaces and other facilities, start is also very simple, the danger is not high, the cost is lower, but the operating costs are higher than other heating methods, thermal efficiency in the following, so it is suitable for heating temperature in the following and the price of electricity is low.

In the stainless steel reaction kettle usually want to carry out chemical reaction, in order to ensure that the reaction can be uniform and faster, improve efficiency, usually in the reaction kettle is equipped with the corresponding stirring device, so it will bring the dynamic sealing of the drive shaft and prevent leakage of the problem. The work of the reactor kettle is mostly intermittent operation, and sometimes to ensure product quality, each batch of material needs to be cleaned after entering the internal maintenance of the equipment.
