The difference between a reactor and a stirred tank
There were many differences between a reaction kettle and a stirred tank: 1. ** In terms of cost **: The reactor has a complex structure and a high cost, while the stirring tank has a simple structure and a relatively low cost. 2. ** In terms of structure ** - ** Top cover structure **: The top cover of the reaction kettle is a head structure or a conical structure; the top cover of the stirring tank can be a flat cover structure or a sealed structure. - ** Overall structure **: The overall structure of the mixing tank is simpler than that of the reaction kettle. It is easy to manufacture and simple to use. 3. ** Sealing **: The reaction kettle has high requirements for sealing, so it needs to use mechanical seals; the sealing form of the stirring tank can be made into mechanical seals or packing seals according to requirements. 4. ** Operation observation **: The reaction kettle can only observe the materials in the tank with the assistance of the mirror, pressure gauge, level gauge and other accessories; the open-cover stirring tank can observe the materials in the tank through the opening of the cover or the manholes, and the observation range is larger than the observation range of the mirror of the reaction kettle. 5. ** Working conditions ** - ** Pressure **: The pressure resistance of the reactor is higher than that of the stirred tank. The reactor usually needs to work under a certain pressure. For example, the stirred reactor often needs to be installed with a mechanical seal to meet the requirements of vacuum packaging or work under a certain pressure. The stirred tank can be sealed with ordinary packing. - ** Temperatures **: There is usually a reaction bed in the reactor and it can be treated at a high temperature to resist heat. For example, the temperature of the materials in the stainless steel reactor can reach 400 degrees Celsius, and the pressure in the reactor can be maintained at dozens of kilograms or even hundreds of kilograms. The stirred reactor is usually equipped with a constant temperature. The temperature of the materials in the porcelain reactor cannot exceed 200 degrees Celsius. If the temperature is too high, it will cause the glaze layer to melt. - ** Function **: The reaction kettle can carry out reactions, and the reaction process is often accompanied by temperature changes. For example, the reaction kettle needs a heating jacket, or an air pipe to heat and cool; the stirring tank is generally only used as a stirring and mixing equipment, not involved in the reaction process, and usually does not need to be heated. 6. ** Stirring paddle types (related to the reaction kettle stirring equipment)**: The widely used stirring paddles in the reaction kettle include paddle type, propeller type, turbine type, anchor type, and frame type. Paddle-type agitators were mainly used to prevent solid settlement in solid liquids; propeller agitators were more commonly used in liquids with low stickiness; turbine agitators could basically complete all stirring operations and were suitable for fluids with a wider range of stickiness; anchor agitators and frame agitators had simple structures and were generally used in situations where mixing requirements were not too strict.

Is the reactor 201 or 304?
201 stainless steel contains high Manganese, low Ni, poor corrosion resistance, easy to rust;304 stainless steel contains more Chromite, easy to rust, strong corrosion resistance. When choosing the reactor to use 201 or 304 stainless steel, it is necessary to consider the corrosion resistance requirements of the working environment of the reactor. If the working environment is not corrosive and sensitive to cost, 201 stainless steel can be considered; if the working environment has certain corrosive requirements, 304 stainless steel is more suitable. At the same time, we must also consider the standards and specifications of different industries. For example, in industries such as medicine and food that have high requirements for hygiene and corrosion resistance, 304 stainless steel may be a better choice. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Is the cracking precipitator a reactor?
The FCCU consisted of a reactor (discharger), a regenerating, and other equipment. The discharger was a part of the reactor. It was not an overall concept of the reactor in a separate sense, but a component of the reactor that carried specific functions in the FCCU reaction system. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Nuclear fission in the reactor
Take Uranium-235 as an example. When the nucleus of Uranium-235 was bombarded by external neutrons, one nucleus would absorb a neutron and split into two smaller nuclei, releasing two to three neutrons at the same time. The neutrons produced by the fission bombarded another Uranium-235 nucleus, causing new fission. If this continued, it would be a fission chain reaction, which would produce a large amount of heat. In order to achieve such a nuclear fission reaction, the reasonable structure of the reactor should include nuclear fuel, moderator, heat carrier, control facilities, and protective devices. The nuclear fuel needed to be made from uranium ore through processes such as selection, crushing, acid soaking, and concentration to produce a certain amount of uranium and a certain geometric shape of the rod. In a traditional nuclear fission reactor, in order to improve the chain fission reaction efficiency of nuclear fuel, it was necessary to decelerate the high-speed neutrons (fast neutrons) produced by fission into slower neutrons (thermal neutrons). A neutron moderator composed of lighter nuclei (such as light water, heavy water, etc.) would be added to use the hydrogen atoms to decelerate the high-speed neutrons. The heat carrier could be used to take away heat to prevent the reactor from burning down due to overheating. The heat that was extracted could turn the water nuclear reactor into steam to drive the gas turbine to generate electricity. The control facility allowed the nuclear reactor to operate according to human wishes. The protective device was because uranium and fission products were highly radioactive and could cause harm to humans. In addition to the traditional reactors that used Uranium-235 as nuclear fuel, there were also fast neutron reactors (nuclear fission reactors without neutron moderators) and thorium-based molten salt reactors (fourth-generation reactor nuclear energy systems that used thorium as nuclear fuel and composite fluorides as coolants). Their nuclear fission reaction principles were similar, but there were differences in specific fuel, efficiency, safety, and so on. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
byd reactor principle
In the BYD reactor, fresh and recycled formalin from the formalin plant entered the liquid phase of the BYD reactor, while the ethyne gas entered the bottom of the reactor and dispersed in the liquid-solid phase. Under the effect of the catalyst, the reaction occurred to form 1,4-butynegol (C2H2 + 2HHamster → HOCH2C = ccH20H (BYD)). After the pulp in the ByD reactor was filtered by the candle filter in the reactor, the filtered liquid entered the ByD collection tank (BD-V104). The reactor's internal components included a candle filter, an ethyne loop, a stirring device, a cooling coil, etc. The shell was made of Q345R + 316L. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The filter in the photocatalysis reactor
The optical filter in the photocatalysis reactor played an important role in many aspects. First of all, it could filter light and only allow light of a specific wavelength to pass through, thereby achieving fine control of the reaction light source, which helped to improve the specialization and efficiency of the biochemical reaction. Secondly, different filter had different spectral transmissances, which could be used to control the light intensity and spectral distribution during the reaction process. This would not only help in the optimization of experimental conditions and increase the purity and yield of the product, but also help to reduce the occurrence of side reactions and reduce energy consumption and experimental costs. In addition, the filter also had the function of protecting the photocatalysis reactor. Some light sources would generate high temperatures during long-term operation, which could cause the performance of the instrument to decline or even be damaged. The filter could effectively filter out excess light and reduce the heat of the light source, thereby extending the service life of the instrument. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
