Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reactors, in particular to a high-temperature solid phase reactor for catalyst preparation. Background Art
[0002] Solid-phase reaction is the process of chemical reaction between solids to generate new solid products. There are different ways to classify solid-phase reactions. According to different reaction mechanisms, they can be divided into diffusion-controlled processes, chemical reaction rate-controlled processes, crystal nucleation rate-controlled processes, and sublimation-controlled processes. According to different states of reactants, they can be divided into pure solid-phase reactions, gas-solid-phase reactions, liquid-solid-phase reactions, and gas-liquid-solid-phase reactions. According to different reaction properties, they can be divided into oxidation reactions, reduction reactions, addition reactions, replacement reactions, and decomposition reactions.
[0003] Since some solid-phase reactions require heating, existing reactor designs do not fully consider heating needs. These reactors often lack built-in heating devices or their heating systems are not efficient, which leads to a major problem for researchers and engineers when conducting solid-phase reactions that require heating. When there is no appropriate heating mechanism, the reactants may not reach the necessary activation state, which can seriously affect the progress of the reaction. In some cases, the reactants may not react fully due to insufficient heat, which not only leads to a decrease in reaction rate, but also may lead to a decrease in the yield of the target product or even the generation of undesirable byproducts.

The end of the heating tube away from the oil pipeline is connected to an L-shaped third connecting tube, and the end of the third connecting tube away from the heating tube is connected to an oil outlet pipe. The end of the oil outlet pipe is connected to the auxiliary heating tube and is on the same side as the oil inlet pipe. They are respectively located at the upper and lower ends of the auxiliary heating tube to achieve the purpose of bottom-in and top-out. The heating oil circulates inside the auxiliary heating tube through a water pump. Several heating rods heat the heating oil through the heating tubes wrapped around their sides, and transport it through several connecting tubes connected to them.

[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] The utility model achieves the purpose of heating the material through auxiliary heating pipes, heating pipes, connecting pipes, heating rods and water pumps. The device achieves high efficiency in the transfer and utilization of heat energy through structures such as heating pipes. The heating oil is rapidly heated by the heating rod in the heating pipe. Then the heating oil excited by the high temperature flows through the auxiliary heating pipe and transfers the heat to the catalyst in the reaction tank.

During the whole process, the heating oil circulates continuously in the closed system, which not only avoids the waste of heat energy, but also ensures the safe and stable operation of the system. At the same time, because the heating oil has excellent thermal stability and temperature resistance, the design can adapt to various complex industrial conditions and needs. It not only ensures the smooth progress of the catalytic reaction, but also improves the preparation effect of the catalyst. BRIEF DESCRIPTION OF THE DRAWINGS
