Description

Technical Field

[0001] This utility model relates to the field of instrument technology, and more specifically, to a portable oil and gas recovery detection device. Background Technology

[0002] Oil and gas recovery detection devices are mainly used to test the effectiveness of oil and gas recovery systems in gas stations, oil depots, and other similar locations. They can measure parameters such as oil and gas concentrations in these areas to confirm whether the oil and gas recovery system is operating normally and to reduce environmental pollution from oil and gas evaporation.

[0003] Current oil and gas recovery detection devices typically employ active air intake, creating a negative pressure environment inside the sampling tube by connecting an external air extraction device, such as a small vacuum pump or air extraction pump. This draws external gas into the sampling tube due to the pressure difference. The air extraction device can control the flow rate and velocity of the intake air to meet different sampling requirements.

[0004] However, since the oil and gas detection area is of a certain size, the results of single-point gas sampling are not very representative. At the same time, the results of single-time-node sampling are also not very representative. Therefore, in order to obtain more accurate results from the possible oil and gas environment that people are exposed to, it is necessary to design a multi-point collection and multi-node sampling scheme to more accurately measure parameters such as environmental oil and gas concentration, and to more accurately reflect whether the oil and gas recovery system is operating normally. Utility Model Content

[0005] To address the technical problem of needing to design multi-point acquisition and multi-node sampling schemes as mentioned in the background art, this utility model utilizes a timing module equipped with multiple sampling interfaces and arranges a sampling pipeline system at the testing site to achieve the functions of timing and multi-point sampling. The gas is temporarily stored in a gas mixing tank, detected by a gas detection module, and the test results are displayed through a data transmission and display module, thus realizing a multi-point acquisition and multi-node sampling scheme.
