The working principle and main characteristics of the outer coil reactor
When designing and manufacturing the outer coil reactor, the pressure, temperature, material, stirring device type, speed, sealing structure and heating method are often combined with the production requirements of the material and the actual needs of the user at the same time. The lower part of the outer coil reaction kettle is provided with a discharge hole, a stirrer is arranged in the kettle, and a reaction solvent is placed in the inner layer for stirring reaction.
In practical applications, we can pass different cold and heat sources, such as refrigerating liquid, hot water or hot oil, into the interlayer of the outer coil reactor to perform cyclic heating or cooling reactions. In this way, through the interlayer of the reactor, a constant temperature (high or low temperature) hot melt medium or cooling medium is injected to heat or cool the materials in the reactor at a constant temperature. In addition, the stirring reaction can be carried out under normal pressure or negative pressure according to user requirements.
Generally, multiple pipe holes are opened on the lid of the outer coil reactor, such as process pipe holes for feeding, stirring, observation, temperature measurement, pressure measurement, steam extraction and fractionation, and safe venting. In addition, the heating coil is provided with connection holes for inlet and outlet of oil (steam), temperature measurement, and venting, which can be heated or cooled by steam, heat transfer oil, and water. For users, the product has the characteristics of rapid heating, high temperature resistance, corrosion resistance, sanitation, no environmental pollution, no need for automatic boiler heating, and convenient use.
Not only that, the structural design of the outer coil reactor is also unique. At the same time, due to its spiral-shaped outer coil half-pipe design, it can not only reduce the wall thickness of the reactor body and increase the pressure capacity of the reactor body, but also help Improve heat transfer efficiency. It can not only increase the thermal coefficient, but also reduce the thermal resistance. In practical applications, energy consumption can also be reduced. In addition, its own structural design is relatively special, so the overall diameter of the kettle body can also be reduced, which is beneficial to the layout of the workshop.
In comparison, the amount of steel can be saved when designing and manufacturing the outer coil reactor. At the same time, it can also increase the flow rate of the medium in the coil, and the high-speed flowing medium can effectively prevent fouling on the inner surface of the jacket. For some cooling process operations, this product can also meet its application requirements. Under normal conditions, its operation is stable and reliable, with low noise, easy to clean, and can be used continuously to disperse and stir materials.
The sealing effect of the outer coil reactor is also good, so there is no need to worry about leakage during use. Because the outer coil reactor adopts built-in discharge, it can ensure that the discharge is clean and free of residue, so it can meet the requirements of equipment and equipment with too much structure in the kettle or too many holes on the kettle.
