Problems solved by technology

Due to the uneven gas mixing in the gas storage tank, the process quality will be reduced when the gas storage tank is transported to the production site for use
In addition, this method of inflating and mixing first and then transporting the gas storage tank to the site for use still has the disadvantages of cumbersome operation and high labor intensity
In addition, the valves installed on the existing pipelines are likely to cause the sealing failure of the valves when transporting high-temperature, high-pressure and corrosive gases. This problem also needs to be solved urgently

Abstract

The invention discloses an online gas mixing device with a function of accurately regulating mixing ratios. The online gas mixing device comprises a first gas inlet pipeline, a second gas inlet pipeline, a mixer and a mixed gas outlet pipeline. A first manual regulating valve, a first pressure gauge and a first flow meter are sequentially arranged on the first gas inlet pipeline along a gas flow direction, and a second manual regulating valve, a second pressure gauge and a second flow meter are sequentially arranged on the second gas inlet pipeline along a gas flow direction; two gas inlet branch pipelines are connected with the second gas inlet pipeline by a three-way pipe. The online gas mixing device has the advantages that the online gas mixing device is reasonable in design, and more than two types of gas can be uniformly mixed with one another in the pipelines in gas delivery procedures; the gas input can be regulated according to the mixing ratios, the online gas mixing device is high in regulation precision, and good mixing effects can be realized; the manual regulating valves are good in high-temperature resistance and corrosion resistance, excellent sealing effects can be realized, the sealing is easy to regulate, and the manual regulating valves are convenient to maintain and replace.

Description

technical field [0001] The invention relates to the technical field of gas uniform mixing, in particular to an online gas mixing device for precisely adjusting the mixing ratio. Background technique [0002] In some production enterprises, it is usually necessary to mix two gases in real time and output a mixed gas with a relatively constant temperature and pressure. At present, the general method is to fill these two gases into the high-pressure gas tank successively. During the inflation process, the two gases are mixed, and after the inflation is completed, they are mixed under static conditions. Due to the different molecular weights of the two gases (different specific gravity) ), self-mixing under static conditions will appear that the specific gravity is located in the lower part of the gas storage tank, and the specific gravity is located in the upper part of the gas storage tank. Due to the uneven gas mixing in the gas storage tank, the process quality will be redu...
