Abstract

The invention discloses a surface impurity removal system for a gas field flow measurement device, which includes a main system including a pipeline module and a control module, wherein the pipeline module includes a first air inlet pipe, a measurement circuit, a dust outlet pipe and a second pipeline module. An air outlet pipe, the first air inlet pipe is connected to the measurement circuit at the first interface, the dust outlet pipe is connected to the measurement circuit at the second interface, the first air outlet pipe is connected to the dust outlet The third interface at the middle part of the tube is connected; the measurement circuit includes a switching tube and a detection tube, and the detection tube communicates with the fourth interface and the fifth interface on the switching tube; through the main system and the backup system Switching enables the standby system to be activated when the main system fails, achieving the purpose of uninterrupted measurement; it can realize flow measurement while cleaning impurities, and the cleaning effect is more excellent by using the two-way impurity removal method.

Description

technical field [0001] The invention relates to the technical field of gas field metering, in particular to a surface impurity removal system and method for a gas field flow measurement device. Background technique [0002] With the enhancement of global environmental protection awareness, people's demand for energy is getting higher and higher. The excessive use of traditional coal, oil and other energy sources has brought great pollution to the environment. Therefore, my country's demand for clean energy continues to increase, and oil and gas fields, The exploration and development of natural gas fields are also paid more attention to. In the process of gas field exploitation, accurate measurement of the extracted oil and gas and natural gas ensures the safe and reliable transportation of gas, which is conducive to providing scientific and accurate data for subsequent exploitation and resource allocation, which must involve the use of flow measurement devices. [0003] The...
