High-purity gas pipeline constant temperature system for experiment

Abstract

The invention discloses a high-purity gas pipeline constant temperature system for experiment. The high-purity gas pipeline constant temperature system comprises a gas pipeline, and further comprises a gas extracting and supplying device, a constant temperature box, a reactor, a heating block, a heating wire and a temperature sensor, wherein the constant temperature box is divided into a first box body, a second box body and a third box body through two layers of division plates; the gas pipeline of the gas extracting and supplying device is divided into two branch pipes; the first branch pipe penetrates through the first box body of the constant box body, and the second branch pipe penetrates through the second box body of the constant box body; the two branch pipes are connected with the reactor after being gathered. The heating block and the heating wire are arranged in the constant temperature box, so that gas flowing through the constant temperature box reaches the experiment temperature meeting the requirement, and the effects of preserving and stabilizing the temperature are achieved; furthermore, the gas pipeline is divided into the two branch pipes respectively adopting a snake-shaped structure and a linear structure; the first branch pipe with the snake-shaped structure can enhance the gas travel under the condition that the size of the box body is the same, and the temperature increase effect is better.

Description

technical field [0001] The invention relates to a high-purity gas experiment system, in particular to a high-purity gas pipeline constant temperature system for experiments. Background technique [0002] In the experiment process of some high-purity gases, due to the limitation of the nature of the high-purity gases in various experiments, it is necessary to maintain a certain temperature in the experiment, so that the experiment can be carried out better and reliable experimental data can be obtained. [0003] For example, some gases will liquefy when the temperature is lowered, which will reduce the amount of gas when entering the experimental equipment or reactor, which will affect the experimental results, or when performing catalytic reactions or other experiments, high-purity gases must reach a certain experimental temperature. , in order to successfully complete the experimental content, so a system that can keep the temperature of the high-purity gas constant when it...
