Problems solved by technology

[0002] The tracking and determination of gases in the photocatalytic process has always been difficult
Large-scale flowmeters are inconvenient to use in the experimental field. They only reflect changes in readings, and it is not convenient to qualitatively determine the composition of gases. They are sensitive to corrosive gases, so their applications are limited and they are relatively expensive.
Through the summary of gas measuring devices at home and abroad, we found that all kinds of devices have their application limitations, and it is difficult to meet the needs of research, production and teaching in the field of photocatalysis

Embodiment Construction

[0015] A preferred embodiment of the present invention is described as follows in conjunction with accompanying drawing:

[0016] Referring to the accompanying drawings, the gas volume change tracking device of the photocatalytic gas measurement system consists of a tee 3, a scale glass 4, a liquid storage tank 5, a glass tube and a latex tube 7. The bottom outlet of the liquid storage tank 5 is connected to the lower port of the vertically installed scale glass tube 4 through the latex tube 7, and the upper port of the scale glass 4 is connected to the two interfaces 1, 2 via the latex tube 7 and the tee 3.

[0017] The above-mentioned one interface 1 is connected with the device with measurement, and the other interface 2 is connected with the initial gas supply system.

[0018] There is an effective amount of liquid 8 in the above-mentioned liquid storage tank 5, and an opening 6 above the liquid storage tank 5 communicates with the atmosphere.

Abstract

The invention relates to a tracking device for variation of gas volume in a photocatalysis gas measuring system, which is composed of a tee, a graduated glass tube, a liquid reservoir, a glass tube and a latex tube. A bottom outlet of the liquid reservoir is communicated with a lower port of the graduated glass tube through the latex tube, and the upper port of the graduated glass tube is communicated with two connections via the latex tube and the tee, wherein one connection is connected with a device with a measurer and the other connection is connected with an initial gas supply system. The device is capable of real-time tracking light-catalyzed reaction, understanding the variation condition of the activity of catalyst, and accurately understanding the variation condition of reactant along with the reaction time by real-time obtaining gas phase samples for analyzing. The tracking device is simple in structure and easy in construction, and can be applied to the field of tacking and measurement of volume change.

Description

Technical field: [0001] The invention relates to a photocatalytic gas measurement device, in particular to a gas volume change tracking device of a photocatalytic gas measurement system, which can be applied to the field of volume change tracking measurement. technical background: [0002] The tracking and determination of gases in the photocatalytic process has always been difficult. Large-scale flowmeters are inconvenient to use in the experimental field. They only reflect changes in readings, and it is not convenient to qualitatively determine the composition of gases. They are sensitive to corrosive gases, so their applications are limited and they are relatively expensive. Through the summary of gas measuring devices at home and abroad, we found that all kinds of devices have their application limitations, and it is difficult to meet the needs of research, production and teaching in the field of photocatalysis. It is promising to invent a practical and economical photo...
