Original Title Simple and Easy to Understand Classification Advantages and Disadvantages and Selection of Various Reactor Agitators The agitator is one of the key components of the reactor According to the physical properties capacity and stirring purpose of different media in the reactor the selection of the corresponding agitator can play a great role in promoting the chemical reaction speed and improving the production efficiency Mastering the classification and application of the agitator is helpful to choose the right agitator to achieve better reaction effect Learn from Xiao Qi! Application of reaction kettle Reactor is a pressure vessel widely used in petroleum chemical industry rubber pesticides dyes medicine and food to complete the process of vulcanization cbd centrifugal extractor nitration hydrogenation alkylation polymerization and condensation The composition of the reactor Expand the full text The reaction kettle consists of a kettle body a kettle cover a jacket a stirrer a transmission device a shaft sealing device a support and the like 1 Shell of reaction kettle The shell consists of a circular cylinder an upper cover and a lower end socket There are two ways to connect the upper cover and the cylinder one is to weld the cover and the cylinder directly to form a whole; the other is to consider the convenience of disassembly Flange connection is available The flow pattern depends on the form of the agitator the geometry of the agitator vessel and internals as well as fluid properties agitator speed and other factors Axial flow The flow direction of that fluid is parallel to the stir shaft jacketed glass reactor and the fluid is pushed by the blade to flow downward and then turn upward when meeting the bottom surface of the container to form an up-and-down circulating flow Radial flow
The folding blade type has less power consumption and lower operating cost than the straight blade type so the folding blade propeller is used more The paddle type agitator cannot be used in the gas-liquid dispersion operation for the purpose of keeping the gas and for the purpose of fining The rotating speed of the paddle agitator is generally 20 ~ 100 R/min and the common parameters are shown in the following table 2 Propeller hemp extraction centrifuge agitator The propeller-type stirrer can make the materials circulate in the reaction kettle during stirring and the function is mainly volume circulation the shearing function is small and the up and down tumbling effect is good When a larger flow rate is required the reaction kettle is internally provided with a guide cylinder
