1. structure small stainless steel reactor structure is basically the same, in addition to the stainless steel reactor body, and transmission device, stirring and heating (or cooling) device, can improve the heat transfer conditions, the reaction temperature control is more uniform, does not strengthen the mass transfer process. 2. operating pressure small stainless steel reactor operating pressure is higher. The pressure in the kettle is produced by a chemical reaction or by an increase in temperature. The pressure fluctuates greatly, sometimes the operation is unstable, and the sudden pressure increase may exceed several times the normal pressure. Therefore, most stainless steel reactors are pressurized vessels. 3. operating temperature small stainless steel reverse

1. structure 
SmallStainless steel reaction kettleThe structure is basically the same,Stainless steel reaction kettleIn vitro, there are transmission devices, stirring and heating (or cooling) devices, etc., which can improve the heat transfer conditions, so that the reaction temperature is controlled more evenly, and the mass transfer process is not enhanced. 
2. operating pressure 
SmallStainless steel reaction kettleThe operating pressure is higher. The pressure in the kettle is generated by a chemical reaction or formed by an increase in temperature. The pressure fluctuates greatly, and sometimes the operation is unstable. The sudden pressure increase may exceed several times the normal pressure.Stainless steel reaction kettleIt belongs to pressurized vessel. 
3. operating temperature 
SmallStainless steel reaction kettleThe operating temperature is high, usually chemical reactions need to be carried out under certain temperature conditions, soStainless steel reaction kettleWithstand both pressure and temperature. The methods of obtaining high temperature are usually the following: 
1. Water heating
When the temperature is not required, it can be used, and its heating system is open and closed. 
2. Steam heating
The heating temperature isBelow 100 ℃, steam below one atmospheric pressure can be used for heating; in the range of 100~180 ℃, saturated steam is used; when the temperature is higher, high pressure superheated steam can be used.
3. Heating with other media
If the process requires operation at high temperature or to avoid the use of high-pressure heating system, other media can be used instead of water and steam, such as mineral oil (275~300 ℃), diphenyl ether mixture (boiling point 258 ℃), molten salt (140~540 ℃), liquid lead (melting point 327 ℃), etc.
4. Electric heating
Wrap the resistance wire aroundStainless steel reaction kettleOn the insulation layer of the cylinder, or installed onStainless steel reaction kettleseveral distances on the ad hoc insulator, so that the resistance wire andStainless steel reaction kettleA small space gap is formed between the bodies. 
The first three methods to obtain high temperature all need to add a jacket on the kettle body. Due to the large range of temperature change, the jacket and shell of the kettle bear temperature change and produce temperature difference pressure. When electric heating is used, the equipment is lighter and simpler, the temperature is easier to adjust, and there is no need for pumps, furnaces, chimneys and other facilities, the start is also very simple, the risk is not high, the cost is low, but the operating cost is higher than other heating methods, The thermal efficiency is in85%, so it is suitable for heating temperature below 400 ℃ and the price of electricity is low.
4. stirring structure 
in smallStainless steel reaction kettleIn order to ensure that the reaction can be carried out evenly and quickly, improve efficiency, usually in.Stainless steel reaction kettleThe corresponding mixing device is installed, so it brings the dynamic seal of the drive shaft and the problem of preventing leakage. 
Small 5.Stainless steel reaction kettleThe work 
  Stainless steel reaction kettleMost of them are clearance operations. Sometimes, in order to ensure the quality of products, each batch of materials needs to be cleaned after discharging. The top of the kettle is equipped with quick-opening manholes and hand holes, which are convenient for sampling, measuring volume, observing reaction conditions and entering the equipment for internal maintenance.
