Types and Characteristics of Tubular Reactors
Tubular reactors come in many types, each with distinct characteristics and applicable industries. However, they all are suitable for phase reaction, vapor-phase reaction, and pressure reaction. Below is a detailed introduction.
① The tubular reactor is divided into a sliding reactor and a column reactor, with the sliding reactor characteristics suitable for liquid phase.
The vertical reactor is suitable for processes such as hydrogenation, phase oxidation-reduction reactions, and others.
③ The coil reactor is designed in a fan coil configuration, making the equipment compact and easy to use, as well as convenient for maintenance and cleaning. There are many coil reactors composed of horizontally overlapping fan coils. Each fan coil consists of many semi-circular pipes of different radii interconnected in a spiral manner. The spiral center leaves an open space for indoor installation and maintenance.
④ The multi-tube reactor features a large total heat exchange area, suitable for the entire process with significant thermoelectric effects, as well as for the entire process of gas-solid and liquid-solid heterogeneous catalytic reaction rates. The reaction tubes of the multi-tube reactor can also be filled with solid particles to enhance liquid flowability or promote excellent contact of heterogeneous fluids, and are primarily used to store heat to better control the environmental temperature of the reactor.
⑤ The tubes of the U-shaped reactor are equipped with baffles or mixing equipment to enhance heat transfer and the heat transfer process. The large orifices of the U-tubes increase the residence time of raw materials, making them suitable for reactions that are relatively slow.
The standard function of a tubular reactor
This nuclear reactor design stands out uniquely compared to other reactor designs. The distinctive features of this design will be vividly illustrated in this section, highlighting its differences from other types of reactors. A fuel rod is produced.
A cylindrical fixed bracket is formed within this type of fuel rod to create a fuel assembly. The two main parts of the rod are inserted into the working pressure tube. Since the fuel safety channel is blocked and can be removed from the core, the tube reactor can supply uranium oil during the operation of the nuclear reactor. After the fuel is loaded into this sturdy metal hose, the working pressure tube is vertically arranged inside the reactor core. Cool light water passes through it, absorbing heat from the fuel assembly. This allows the fuel to cool and heat the light water. Under these conditions, water is released as steam from the top of the rock sample. The shell structure in non-modern nuclear power plants is complete. In the Chernobyl accident, it was proven to be ineffective, as the internal working pressure from the top of the core escaped and exposed the radioactive material to the outside. The vessel is made of concrete and metal and can act as a shielding layer. The control rod is made of boron carbide, which serves to absorb hydrogen nuclei. This controls the fission speed within the nuclear reactor; as the control rod moves further into the core, it absorbs more hydrogen nuclei, slowing down the rate of fission.
