Description

TECHNICAL FIELD

[0001] The utility model relates to static mixing technical field more specifically, it relates to a kind of static mixers of gas hydrogen doping. BACKGROUND

[0002] In some conventional gas hydrogen doping static mixers, the installation method of mixing element is relatively simple, and the common one is to fix the mixing element directly on the inner wall or support structure of the mixer. Since the fixing method is not accurate enough, the mixing element is prone to displacement or loosening during operation. Especially when the gas flow speed is high or the pressure changes greatly, the stability of the mixing element will be greatly affected, which may lead to uneven mixing effect and even affect the stability of gas flow. Since the mixer needs to handle gases of different temperatures during operation, temperature changes will cause the material to expand or shrink, thereby affecting the fixing stability of the mixing element. If the installation structure does not have enough adaptability, the mixing element is prone to loosening or deformation, causing uneven mixing.

[0003] With the long-term use of gas hydrogen doping static mixers, the performance of the mixing element will gradually decline, especially in the case of poor mixing effect, pollution accumulation or element damage, disassembly and replacement are needed.
