Embodiment 1
[0048] refer to Figure 1~3 , this embodiment provides a system for removing surface impurities of a gas field flow measurement device, including:
[0049] The main system S1 includes a pipeline module 100 and a control module 200, wherein,
[0050] The pipeline module 100 includes a first air inlet pipe 101, a measurement circuit 102, a dust outlet pipe 103 and a first air outlet pipe 104. The first air inlet pipe 101 is connected to the measurement circuit 102 at the first interface A, and the dust outlet pipe 103 is connected to the measurement circuit The circuit 102 is connected, and the first air outlet pipe 104 is connected with the second interface B at the middle part of the dust outlet pipe 103;
[0051] The measurement circuit 102 includes a four-way conversion ball valve 102a and a detection tube 102b. The four-way conversion ball valve 102a is arranged at the connection between the dust outlet pipe 103 and the measurement circuit 102; The ball valve 102a is conn...
Embodiment 2
[0065] refer to Figure 1~5 , the present embodiment provides a method for removing surface impurities of a gas field flow measurement device, which is implemented by using the above-mentioned system for removing surface impurities of a gas field flow measurement device, specifically as follows:
[0066] In the working state of the main system S1, close the fifth valve 502 and the sixth valve 602, open the first valve 201 on the first air inlet pipe 101 and the fourth valve 204 on the first air outlet pipe 104, and select the main system S1 to work;
[0067] Send the measured flow to the air inlet, adjust the valve of the control module 200 to make the measured flow pass through the flow meter 102c;
[0068] Switch the valve switch, close the first valve 201 and the fourth valve 204, open the fifth valve 502 and the sixth valve 602, select the standby system S2 to work, and clean the main system S1;
[0069] Start the cleaning pump 301, deliver the flushing fluid to the measu...
