Embodiment 1

[0021] The gas production test system of the biogas project in this example is composed of a precision flowmeter 3 and a soft bag 4. One end of the precision flowmeter 3 is connected to the original measuring interface on the gas pipeline 2, and the other end is connected to the soft bag 4 through a valve 7.

[0022] The precision flowmeter 3 is a precision flowmeter capable of measuring gas flow, gas pressure and gas temperature.

[0023] The method of using the gas production test system of this biogas project is as follows:

[0024] First close the valve 5 and valve 6 at both ends of the original measuring interface on the gas pipeline 2, close the valve 7, connect one end of the precision flow meter 3 to the original measuring interface on the gas pipeline 2, and connect the other end to the soft bag 4 through the valve 7 connect;

[0025] Open the valve 5 and read the atmospheric pressure P after the precision flow meter 3 stabilizes 0 , biogas pressure P 1 , temperatu...

Abstract

The invention discloses a gas production rate testing system for methane project, belonging to the energy field. The gas production rate testing system is composed of a precision flowmeter 3 and a soft bag 4, wherein one end of the precision flowmeter 3 is connected with an original measurement interface on a gas pipeline 2, and the other end of the precision flowmeter 3 is connected with the soft bag 4 by a valve 7. The gas production rate testing system can overcome the defects that the existing gas production rate testing system for methane project has low accuracy and narrow applicability and the measurement values of the gas production rates do not have lateral comparability. The gas production rate testing system for methane project is simple, and can be operated conveniently; and the measurement result is stable and reliable and has lateral comparability.

Description

Technical field: [0001] The invention belongs to the field of energy, and in particular relates to a gas production test system for a biogas project. Background technique: [0002] Measuring the gas production of a biogas project over a period of time is an important parameter to detect the design level and construction quality of the biogas project. For biogas projects in operation, non-destructive detection methods should be used to measure the gas production to ensure that the biogas projects can operate normally before and after the measurement. There are two methods for measuring the gas production of existing biogas projects. One method is to use the existing flow meter on the gas transmission pipeline of the project to record the 24-hour gas production; the other method is to use the wet gas storage tank of the biogas project to measure The cross-sectional area of ​​the floating cover of the gas storage tank is converted to the gas production by recording the rising ...
