Multi-gas uniform mixing tank

The invention discloses a multi-gas uniform gas mixing tank which comprises a gas mixing tank body, and a first gas mixing mesh plate, a second gas mixing mesh plate, a third gas mixing mesh plate and a fourth gas mixing mesh plate are arranged in the middle of the interior of the gas mixing tank body according to different heights. The first gas mixing mesh plate, the second gas mixing mesh plate, the third gas mixing mesh plate and the fourth gas mixing mesh plate penetrate through the circle center and are fixedly provided with mesh plate connecting columns, a first mixing cavity is formed between the first gas mixing mesh plate and the second gas mixing mesh plate, and a second mixing cavity is formed between the second gas mixing mesh plate and the third gas mixing mesh plate. A third mixing cavity is formed between the third gas mixing mesh plate and the fourth gas mixing mesh plate. According to the multi-gas uniform gas mixing tank, the problem that gas entering independently cannot be homogenized in
