Problems solved by technology
The disadvantage of these traditional test instruments is that the measurement of oil and gas concentration by these devices is not comprehensive enough, and all of them need to be wired with the outside world to power on the equipment, and often near the oil and gas concentration field, electrical explosion protection needs to be vigilant at all times, and the use of equipment has certain security risks

Embodiment Construction
[0015] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0016] Such as Figure 1 ~ Figure 3 A non-destructive testing device for a movable nanometer oil and gas concentration field is shown, including a data acquisition and signal sending module and a signal receiving and data analysis and processing module.
[0017] The data collection and signal sending module has a base 4 which can be moved and fixed. The base 4 is 1500mm long, 500mm wide and 40mm high. A brakeable wheel set consisting of a wheel 1 and a brake lever 2 is arranged under the base, and the brakeable wheel set is fixed under the base 4 through a connecting rod 3 . The diameter of the wheel 1 is 150mm. When in use, move the test equipment to the de...

Abstract
The invention relates to a non-destructive testing device for a movable nano-type oil and gas concentration field, which includes a data acquisition and signal transmission module and a signal reception and data analysis and processing module. The data acquisition and signal transmission module has a base, and a pair of retractable The bracket is fixed with barbed wire between the upper ends of the telescopic bracket, and the wire net is provided with a number of thermal conductivity detectors arranged longitudinally. An electrical signal transmitter for electrical signals; the signal receiving and data analysis and processing module includes an electrical signal receiver for receiving the electrical signal of oil and gas concentration sent by the electrical signal transmitter, and the electrical signal receiver is connected to a chromatographic workstation. The thermal conductivity detector used in the present invention has high sensitivity and is in direct contact with the oil and gas to be tested during detection, and the detected electric signal can convert the generated chromatographic peak value into an oil and gas concentration fitting curve through the chromatographic workstation.
Description
technical field [0001] The invention relates to the technical field of oil and gas concentration field testing, in particular to non-destructive testing equipment for a movable nanometer oil and gas concentration field. Background technique [0002] At present, most of the oil and its products on the market are stored in storage tanks. During the storage process, due to factors such as environmental changes and equipment conditions, liquid oil products often evaporate and emit a large amount of organic gases into the atmosphere. , resulting in loss. This not only brings serious waste of resources and economic losses to enterprises and society, but also seriously pollutes the environment. At the same time, the leaked and diffused oil and gas are a great safety hazard, which poses a great risk to the safety of people's lives and property. [0003] Existing methods for testing the concentration of oil and gas mainly include combustible gas detectors, gas chromatographs and oth...
