Staged-temperature-controlled reactor and stirring shaft thereof

Abstract

The invention discloses a staged-temperature-controlled reactor and a stirring shaft thereof and belongs to the technical field of reactors. The reactor comprises a chamber body and the stirring shaft, wherein the chamber body contains reactants, the stirring shaft can rotate in the chamber body so as to stir the reactants, a first chamber and a second chamber are arranged at the two ends of the stirring shaft, a partition plate is arranged between the first chamber and the second chamber so as to isolate the two chambers, heat exchange media of different temperatures flow in the two chambers, the reactants in the chamber body will be subjected to heat exchange due to the first and second chambers so as to achieve staged temperature control, and thus, the reactants can be subjected to a heated reaction and cooling treatment simultaneously in one chamber body. Thus, temperatures of the materials in the chamber body at upper and lower stages are controllable, the function of simultaneously controlling inside and outside temperatures of the chamber body is achieved, and the diversity and practicability of functions are improved to the maximum.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a segmented temperature-controlled reactor and a stirring shaft thereof. Background technique [0002] Chemical reactions usually generate a lot of heat, so a heat exchange device is often installed on the reactor to control the temperature of the chemical reactor. Many companies still use manual control. During normal driving and parking, in order to ensure the reaction temperature, heat media such as water or heat transfer oil are used to heat the material, and a large amount of heat is released after the reaction occurs. If the product cannot be discharged in time, overheating will lead to the activity of the generated material. Ineffective, so the traditional way of working is to arrange workers in the operating room to observe the reaction temperature on the operating panel and make timely adjustments. [0003] If the temperature is too high, a cold source valve is opened ...

Problems solved by technology

These reactors are used in the rapid reaction process, not only the response is not timely, but also it is difficult to ensure sufficient mixing

[0004] Research on the existing mechanical stirrer heat exchange device found that the current structure of the heat exchange device has high energy consumption and poor heat transfer effect. Although the heat exchange device with the mechanical stirrer structure can improve the heat exchange and stirring capacity of the reactor, This structure makes the structure of the reactor and the stirrer complex, and at a certain stirring speed, the stirring power increased by the scraper of the stirrer will be converted into stirring heat, increasing the load of heat exchange

[0005] At the same time, the existing mechanical stirrer can only play the role of stirring and heat exchange. When the chemical reaction is carried out in the tubular reactor, the raw material of the reactant needs to enter from one end of the tubular reactor. The output from the other end of the tubular reactor requires that the mechanical stirrer in the tubular reactor not only needs to have the function of stirring and heat exchange, but also needs to have the function of moving the reactant raw material from one end of the tubular reactor to the other end.
