Multi-component gas simulation mixing system

Abstract

The invention discloses a multi-component gas simulation mixing system, which belongs to the technical field of gas simulation mixing. After each component gas independently enters a rotary mixer, thecomponent gases are fully and uniformly mixed in an annular gas mixing chamber. Water vapor is added by a water vapor generation unit. After relevant parameters of multiple component gases and the water vapor are adjusted through data fed back by a monitoring unit, a simulated mixed gas is obtained and connected into a required system. The system is reasonable in design, wide in application range, easy and convenient to operate and high in efficiency. The concentration and flow velocity distribution uniformity of multiple component gases is improved, and accurate adjustment and control of moisture can be achieved.

Description

technical field [0001] The invention belongs to the technical field of gas simulation mixing, and in particular relates to a multi-component gas simulation mixing system. Background technique [0002] Multi-component gas simulation mixing is widely used in laboratory research, industrial scale-up test and actual industrial production. The simulation mixing effect directly affects the test conclusion and industrial production, and its important role is obvious. The common gas simulation mixing mainly adopts special geometric shapes to make the fluid flow horizontally or disorderly to achieve the purpose of mixing. The concentration distribution and flow velocity distribution of the simulated mixed gas are the key indicators for evaluating the simulated mixing effect. [0003] In scientific experiments and scale-up experiments, the general multi-component gas simulation mixing is relatively easy to realize, but for many components or special components, the multi-component gas...

AI Technical Summary

Problems solved by technology

[0003] In scientific experiments and scale-up experiments, the general multi-component gas simulation mixing is relatively easy to realize, but for many components or special components, the multi-component gas simulation mixing brings people difficulties. Now Some gas simulation methods have some problems and deficiencies

1. When more than four components are simulated, there is poor uniformity of gas concentration distribution, resulting in unstable properties of the simulated mixed gas; 2. The flow rate deviation is large, and the mixing ratio of gas components fluctuates greatly; 3. When water is one of the component gases, There are problems such as difficulty in adding water and difficulty in controlling the concentration of water vapor; 4. There are problems such as unstable pressure of multi-component gases, large temperature fluctuations, and difficult adjustment of single components
