Description

Technical Field

[0001] The invention relates to the technical field of chemical pharmacy, and in particular to a baffle tube box and a reactor. Background Art

[0002] Reactor equipment commonly used in the field of chemical and pharmaceutical technology includes tubular reactors and kettle reactors, among which kettle reactors are often equipped with stirring devices for mixing liquid reactants. The purity of the synthesized product and the reaction conversion rate are low, and the energy consumption and pollution are relatively serious. Since the chemical and pharmaceutical fields have high requirements for product purity, the commonly used reactor equipment is the continuous flow tubular reactor.

[0003] In the continuous flow reactors currently on the market, the pipes are mainly connected in the form of elbows or U-shaped pipes, which have the following problems:

[0004] 1. The traditional connection method is limited by the radius of the elbow or U-shaped pipe, so the pipes must be kept at a long distance, the reactor pipes are relatively sparse, resulting in a larger reactor volume. If the radius of the elbow or U-shaped pipe is small, it is very easy to be damaged during use.

[0005] 2. It is impossible to set up detection, sampling and other instruments in the middle of the pipeline.

[0006] 3. Since the elbow or U-shaped tube is exposed to the outside of the reactor shell and is in direct contact with the air, it absorbs or releases heat in the air, causing the temperature of the reactants in the elbow or U-shaped tube to be different from the temperature of the reactants in the reaction tube in the shell, affecting the reaction rate, the stability and consistency of the reaction process, and ultimately affecting the conversion rate and yield of the reaction products.
