Background The catalyst has the important function in the chemical industry, and can change the chemical reaction rate (increase or decrease) of the reactant without changing the chemical balance and has no change in the quality and chemical property before and after the chemical reaction. In practical use, the catalyst is usually stored in a storage tank, and part of the liquid catalyst has certain requirements on temperature during storage, for example, triethylenediamine, the melting point of a pure product is 158-160 ℃, but a solution (such as 33% in DPG) is easy to precipitate crystals below 15 ℃, the crystals are difficult to redissolve after forming, and active components are likely to be unevenly distributed, so that the catalyst needs to be heated during storage. For example, patent publication No. CN220549508U discloses a constant temperature storage tank for preparing ruthenium zinc catalyst, which heats raw materials inside a main body through an electric heating wire, but since the electric heating wire is fixedly wound outside the main body, distances between catalysts at different positions inside the main body and the electric heating wire are different, which makes it difficult for the electric heating wire to uniformly heat the catalysts at different positions inside the main body, and finally, there may be a temperature difference between the catalysts at different positions inside the main body, so that improvement is required.
