The structure principle and characteristics of the reaction tank are composed of a tank body, cover, jacket, support, stirrer, and transmission device, shaft sealing device, etc. The material and opening can be made according to the user's process requirements. Heating forms are electric heating, oil heating, gas heating, water heating (or cooling), open-fire heating, etc. The jacket form is divided into: jacket type and outer half-pipe type, jacket oil heating type is equipped with an inflow device. Stirring form generally has a paddle type, anchor type, frame type, spiral type, scraping wall type, etc. The high-speed category includes high shear type, propeller type, turbine type, and dispersion impeller type for customers to choose from according to the process. The transmission forms are ordinary motors, explosion-proof motors, electromagnetic speed control motors, frequency converters, etc. The heat exchanger is cycloid pinwheel type, worm wheel type, and planetary infinitely variable speed type. The shaft seal is an ordinary water-cooling packing seal, combined tetrafluoro packing seal, and mechanical seal. The discharge form has a ball valve and a downward-spreading valve.

The reaction tank is a wide variety, with advanced technology, stable quality, smooth transmission, easy operation, and other characteristics. Widely used in petroleum, chemical, food, pharmaceutical, pesticide, scientific research, and other industries, is the use of industry to complete the polymerization, condensation, sulfidation, hydro-carbonation, hydrogenation, and other chemical processes, out and organic dyes and intermediates many processes reaction equipment. I three reaction pot (kettle) variety of specifications, pressure 10MPa out of the next, a volume of 0.1 ~ 10M3 ranging, heating methods are jacketed or coil steam heating, electric heating, oil heating, etc. According to the material production requirements and user needs to determine the pressure, temperature, material, stirring device type, speed, sealing structure, heating mode, etc. to design and manufacture.

Reaction kettles are available in a variety of specifications. The pressure is 10MPa and the volume is 0.1~10M3. Heating methods include jacketed or coil steam heating, electric heating, oil heating, etc. According to the material production requirements and user needs to determine the pressure, temperature, material, stirring device type, speed, sealing structure, heating mode, and other designs and manufacture.

Reaction tank consists of a kettle body, stirrer, cover, jacket, transmission device, support, shaft sealing device, etc. When the stirring device is large in height and diameter, multi-layer stirring paddles are available, and they can also be optional according to the user's requirements. A jacket is set outside the kettle wall, or a heat exchange surface is set inside the vessel, and heat exchange can also be carried out through external circulation. It is advisable to use a gear reducer for a rotating speed over 160 rpm.

A. Usually, a packing seal is used in atmospheric or low-pressure conditions, generally using a pressure of less than 2 kg.

B. Mechanical seal is used in general medium pressure or evacuation situations, the general pressure is negative pressure or 4 kg.

C. In the case of high pressure or high volatility of the medium will be used magnetic seal, with a general pressure of more than 14 kg or more. In addition to the magnetic seal being used to cool down the water, other forms of seals at more than 120 degrees will increase the cooling water jacket.

a. Highly controllable. The reaction kettle can precisely control the reaction process, including temperature, pressure, stirring speed, and other parameters, to meet the needs of different reaction conditions.

b. High reaction efficiency. The reaction tank adopts an optimized structure design and stirring system, which can effectively improve the reaction efficiency and shorten the reaction time.

c. Strong adaptability. The chemical treatment tank can adapt to the needs of different reaction substances, including different reaction media, the concentration of reaction substances, the nature of reaction substances, etc.

d. High safety. The reactor adopts multiple safety protection measures, including a pressure sensor, temperature sensor, safety valve, etc., which can ensure the safety of operators.

e. Easy maintenance. The structure of the reactor is simple and easy to maintain, which can effectively extend the service life.

f. Environmental protection and energy saving. The reaction kettle adopts advanced energy-saving technology, which can effectively reduce energy consumption and also meet the requirements of environmental protection.

The reactor is a comprehensive reaction vessel and the design of the reactor structure function and configuration accessories according to the reaction conditions. It can complete the pre-set reaction steps with a high degree of automation from the beginning of feeding-reaction-discharge and strictly regulate the important parameters such as temperature, pressure, mechanical control (stirring, air blowing, etc.), and concentration of reactants/products in the reaction process. Its structure is generally composed of a kettle body, transmission device, stirring device, heating device, cooling device, and sealing device. Corresponding auxiliary equipment includes a condenser, water divider, fractionation column, collection tank, filter, etc.

Reaction kettle materials generally include zirconium, nickel-based (Hastelloy, Monel) alloy, carbon manganese steel, stainless steel, and other composite materials. The reaction kettle can be made of SUS304, SUS316L, and other stainless-steel materials. The stirrers are the anchor type, frame type, paddle type, turbine type, scraper type, and combined type, and the rotating mechanism can adopt a cycloid reducer, stepless speed reducer or frequency conversion speed control, etc., which can meet the special reaction requirements of various materials. Sealing devices can adopt a mechanical seal, packing seal, and other sealing structures.

The reaction tank is a kind of reaction equipment that must be operated with care, otherwise, it can be damaged for many reasons, forcing production to stop.

a. Be sure to operate the reactor in strict accordance with the rules and regulations.

b. Before the operation, check carefully for any abnormalities. In normal operation, do not open the top cover and touch the terminals on the board to avoid electric shock; operation under pressure is strictly prohibited; in the process of testing pressure with nitrogen, observe carefully the changes of the pressure gauge, and close the nitrogen valve switch immediately when the test pressure is reached; the heating speed should not be too fast, and the pressurization should also be carried out slowly, especially the stirring speed, which is only allowed to rise slowly.

c. When the kettle is heated to a higher temperature, do not contact the kettle to avoid scalding; the experiment should be cooled down first afterward. No quick cooling should be allowed to prevent damage caused by excessive temperature pressure differences. Please remember that the power should be unplugged in time.

In addition to the above aspects, we should pay attention to maintenance after using the reactor so that the autoclave can have a better service life.

Reaction tanks are used in large quantities in the chemical industry. Due to the corrosiveness of the medium, reaction conditions hot and cold, transportation, use, man-made and other problems, there will always be such and such damage to the enamel layer, resulting in unnecessary production stops, such as a large area off, it is recommended to only return to the factory to re-enamel. The enamel kettle price is high, and tiny damage when there is no need to update the whole equipment, which requires the selection of a suitable repair method, otherwise, it will make the reactor kettle solvent corrosion, enamel surface damage will rapidly expand, and the resulting production stoppage, safety accidents and environmental pollution and other unpredictable losses.
