The present application relates to the field of measuring the calorific value of natural gas, in particular to a portable conventional natural gas calorific value measuring device and a measuring method thereof. The integrated box is provided with a top cover that opens or closes the top opening, the first end of the test tube protrudes from the side wall of the integrated box and communicates with the four-way valve, and the test tube is connected to the four-way valve. The second end is located outside the integrated box, the four-way valve is communicated with the air inlet of the laser Raman spectrometer through a pipeline, and the four-way valve is also communicated with the standard gas storage bottle through a pipeline. The third stop valve is arranged on the pipeline between the through valve and the standard gas storage bottle, and the laser Raman spectrometer is electrically connected to the portable computer. The invention can effectively measure the natural gas by communicating with the natural gas pipeline through the test pipe extending from the side wall of the integrated box. The integrated box is easy to move and carry, and solves the technical problem of the lack of portable commercial equipment for measuring the calorific value of conventional natural gas.
Description
technical field [0001] The present application relates to the field of measuring the calorific value of natural gas, in particular to a portable conventional natural gas calorific value measuring device and a measuring method thereof. Background technique [0002] The methods of measuring the calorific value of natural gas include the direct measurement method of calorimeter, the indirect measurement method of components and the correlation method. The direct measurement method of the calorimeter has strict requirements on environmental conditions, complicated operation process, easy to be interfered by human factors, difficult to calibrate the equipment accurately and standardized, and high purchase cost, so its application is relatively limited. Correlation technology uses the relationship between the calorific value of natural gas and its associated physical properties to measure, which is in the research stage and not yet mature. The indirect measurement method of compo...
