Document Type and Number:
WIPO Patent Application WO/2018/192010
Kind Code:
A1
Abstract:
Disclosed is a device for preparing an experimental gas. The device comprises a mixing vessel (1) and several buffer vessels (2) connected in sequence. The mixing vessel (1) and the buffer vessels (2) are respectively provided with an input opening (3) and an output opening (4), with the input opening (3) being connected to a pipeline (5) extending into the respective vessel. The mixing vessel (1) is further provided with an injection opening (7) cooperating with an injector. Further disclosed is a method for preparing an experimental gas by using the device. The method comprises the following steps: (1) respectively inputting a functional liquid and a carrier gas into the mixing vessel by means of the injection opening and the input opening, so as to perform preliminary mixing, and then obtaining a mixed gas; and (2) enabling the mixed gas to successively pass through the buffer vessels so as to be sufficiently mixed, and then obtaining an experimental gas. The above-mentioned device and method are simple in operation, and the prepared experimental gas has an accurate concentration, a relatively wide range, and uniform dispersion.
