Problems solved by technology

[0002] The collection of carbon dioxide in scientific research is currently a difficult point in the industry. The disadvantages of all collection instruments are high cost, expensive maintenance, and difficult to be widely used. When there are many parallel tests, it is difficult to evenly allocate test equipment, which affects the progress.
[0003] At the same time, all the equipment requires high manpower, and it cannot be operated without anyone, which seriously affects the work and rest of the test personnel, because some tests need to last for several days

Embodiment Construction

[0022] Embodiment of the present invention is described below in conjunction with accompanying drawing, embodiment does not constitute limitation of the present invention:

[0023] The device for automatically collecting gas is characterized in that it includes a water-filling device 1 below which includes a drip tube 2, and the drip tube 2 opens downwards, and also includes an air inlet pipe, which is connected to the top of the water-filling device 1 or connected to the On the dripper 2. At least the technical effect that can be realized here is that the gas can be sucked into the water-filling device 1 by the negative pressure.

[0024] The way of realization can be as follows:

[0025] Turn the plastic bucket filled with water upside down, and insert a drip tube into the mouth of the bucket. During the dripping process, a negative pressure is generated in the space above the liquid level. In order to achieve the balance of internal and external pressure, the external gas ...

Abstract

The invention relates to the field of scientific research, especially to an automatic gas collection device and a method thereof. The device provided by the invention contains a water holding device, below which a weep pipe is arranged. The weep pipe is opened at the bottom. The device also contains a gas inlet pipe which is connected above the water holding device or connected to the weep pipe. The invention has beneficial effects as follows: a, field no-power collection is realized; b, by drip control to control air input, environmental gas collection at different time scales is realized; c, multiple gases in the environment are collected simultaneously; d, by quick coupling, operation is simple and fast; e, as ceramic fiber with light weight and good thermal insulation is used to manufacture an electric furnace, the same analysis temperature in the furnace can be obtained better so as to complete analysis and obtain accurate gaseous mass. The device provided by the invention is convenient, fast and accurate, and can be applied in gas collection such as atmospheric environment gas collection, soil respiration gas collection and the like. A molecular sieve collector for collecting carbon dioxide is arranged additionally. By real-time monitoring, reliable data is provided for fields such as energy-saving and emission-reduction monitoring and the like.

Description

technical field [0001] The invention relates to the field of scientific research, in particular to a device and method for automatically collecting gas. Background technique [0002] The collection of carbon dioxide in scientific research is currently a difficult point in the industry. The disadvantages of all collection instruments are high cost, expensive maintenance, and difficult to be widely used. When there are many parallel tests, it is difficult to evenly allocate test equipment, which affects the progress. [0003] At the same time, all the equipment requires high manpower, and it cannot be operated without people, which seriously affects the work and rest of the test personnel, because some tests need to last for several days. Contents of the invention [0004] The purpose of the invention: to provide a device and method for automatic gas collection, low cost, high efficiency and convenient gas automatic collection. [0005] In order to achieve the above object,...
