High-precision rapid gas mixing device capable of rotating reversely

Abstract

The invention discloses a high-precision rapid gas mixing device capable of rotating reversely. The high-precision rapid gas mixing device capable of rotating reversely comprises a rotating motor, a rotating shell, an axial rotating embossment device, a rotating type outer side cavity flow channel, a gradually shrunk gas mixing outlet flow channel, a first mixed gas concentration detecting device,a first mixed gas storage bottle, a rotatable inner tube type flow channel, a mixed gas mode change-over switch, a mixed gas / third gas flow channel, a flow detection and flow channel change-over device, an air pump, a second mixed gas concentration monitoring device and a second mixed gas storage bottle; the rotating type outer side cavity flow channel is inserted in the rotating shell, and is fixedly connected with the rotating shell through the axial rotating embossment device; the rotatable inner tube type flow channel is inserted in the inner barrel of the rotating type outer side cavityflow channel; the left end of the rotating shell and the rotatable inner tube type flow channel are driven by the rotating motor; and the right end of the rotating shell is connected with the gradually shrunk gas mixing outlet flow channel through a rotating hinge. The high-precision rapid gas mixing device capable of rotating reversely is exquisite in structure, good in mixing effect and high inpracticality, the gas mixing speed is increased, and two modes can be switched over.

Description

technical field [0001] The invention belongs to the technical field of gas mixing devices, and in particular relates to a high-precision and fast gas mixing device with reverse rotation. Background technique [0002] In the process of production practice, it is often encountered that flammable, explosive, toxic and other gases need to be discharged. Improper handling of toxic and harmful gases will cause great harm, and may also cause energy waste and environmental pollution, seriously affecting safe production and threatening people. life safety. Traditional gas mixing devices are difficult to mix flammable and explosive gases. When the combustion method is used to deal with flammable and explosive gases, in order to achieve the best combustion effect and reduce the generation of nitrogen oxides, it is necessary to control combustibles and O 2 In addition, if the gas mixture is not uniform, the combustion effect will not be ideal.

Problems solved by technology

[0002] In the process of production practice, it is often encountered that flammable, explosive, toxic and other gases need to be discharged. Improper handling of toxic and harmful gases will cause great harm, and may also cause energy waste and environmental pollution, seriously affecting safe production and threatening people. safety of life

Traditional gas mixing devices are difficult to mix flammable and explosive gases. When the combustion method is used to deal with flammable and explosive gases, in order to achieve the best combustion effect and reduce the generation of nitrogen oxides, it is necessary to control combustibles and O 2 In addition, if the gas mixture is not uniform, the combustion effect will not be ideal

[0003] On the other hand, in scientific research experiments, it is often necessary to use two gases, or even three gases. Rapid mixing occurs before the experiment. If they cannot be mixed evenly before the experiment, it will greatly affect the progress of the experiment and the results of the experiment. accuracy
