Abstract
Description
Technical Field
[0001] This utility model relates to the field of reactors, specifically a protective sleeve for the constant temperature section of a reactor. Background Technology
[0002] In laboratory research in fields such as chemistry, materials science, and biotechnology, reactors are key equipment for conducting various chemical reactions, material synthesis, and biological process studies. The performance of the reactor directly affects the accuracy and reliability of experimental results, and temperature control is one of the key performance indicators of the reactor.
[0003] However, due to the structural characteristics of the heating furnace, the temperature distribution inside the reactor is often uneven, with higher temperatures in the middle and lower temperatures at both ends. This temperature difference can lead to inconsistent reaction rates of the reactants inside the reactor, thus affecting the accuracy and repeatability of the experimental results. Utility Model Content
[0004] To overcome the above-mentioned shortcomings, this utility model provides a protective sleeve for the constant temperature section of a reactor.
[0005] The technical solution adopted by this utility model is as follows:
[0006] A protective sleeve for the constant temperature section of a reactor includes a reaction tube. The protective sleeve is fitted onto the outer wall of the reaction tube. The outer wall of the protective sleeve has honeycomb holes distributed around the outer wall of the protective sleeve. The honeycomb holes in the middle of the protective sleeve have larger diameters and are densely distributed, while the honeycomb holes in the middle of the protective sleeve gradually decrease in diameter and become sparser towards both ends.
[0007] The beneficial effects of this utility model are:
[0008] This invention achieves temperature uniformity inside the reaction tube through the honeycomb hole design of the protective sleeve, reducing temperature difference and improving the accuracy and reliability of experimental results. Attached Figure Description

[0012] In all the attached figures, the reference numerals are as follows: 1. Reaction tube; 2. Protective sleeve; 3. Honeycomb pores. Detailed Implementation
[0013] like Figure 1-3As shown: A protective sleeve for the constant temperature section of a reactor includes a reaction tube 1, and a protective sleeve 2 is fitted onto the outer wall of the reaction tube 1. The outer wall of the protective sleeve 2 is provided with honeycomb holes 3, which are distributed around the outer wall of the protective sleeve 2. The honeycomb holes 3 in the middle of the protective sleeve 2 have larger diameters and are densely distributed, while the honeycomb holes 3 in the middle of the protective sleeve 2 gradually decrease in diameter and become sparser towards both ends.
[0014] Place the reaction tube 1 in a suitable position inside the heating furnace, and attach the protective sleeve 2 to the outer wall of the reaction tube 1, ensuring that the protective sleeve 2 fits tightly against the reaction tube 1 without leaving any gaps.
[0015] Start the heating furnace to begin heating reaction tube 1. Due to the structural characteristics of the heating furnace, the temperature in the middle part of reaction tube 1 will be relatively high, while the temperature at the top and bottom ends will be relatively low.
[0016] The honeycomb holes 3 in the middle of the protective sleeve 2 have a large diameter and are densely distributed. This makes the heat storage capacity of this area low, but the heat conduction capacity high. Therefore, the high temperature in the middle can be quickly conducted to other parts of the protective sleeve 2 through the honeycomb holes 3.
[0017] The honeycomb holes 3 at the top and bottom of the protective cover 2 have small diameters and are sparsely distributed. This slows down the heat conduction speed to some extent, but at the same time, it allows the temperature in these areas to gradually rise, thereby reducing the temperature difference with the center.
[0018] After a period of heating and temperature conduction, the temperature inside reaction tube 1 gradually tends to reach equilibrium, and the temperature difference decreases.
[0019] The protective sleeve 2, through its unique honeycomb hole 3 design, effectively conducts the high temperature in the heating furnace from the middle part to both ends, achieving temperature uniformity inside the reaction tube 1.
