[0030] Reference Figure 1 and Figure 2The residual gas detection device 1 includes a first connecting pipe 11, a second connecting pipe 12 and a gas receiving box 13. The first connecting pipe 11 and the second connecting pipe 12 are both L-shaped pipes. The gas receiving box 13 is a cube.

To ensure the sealing performance, the residual gas detection device 1 is installed on the gas pipeline by welding.

[0031] Reference Figure 1 and Figure 2 The residual gas detection device 1 also includes a first control switch 14 installed on the first connecting pipe 11, and a second control switch 15 installed on the second connecting pipe 12. The first control switch 14 and the second control switch 15 are both used to control the flow rate of gas, and the first control switch 14 and the second control switch 15 are both electrical control switches.

The other end of the purge pipe 16 is connected to an external gas filling device. The external gas filling device adds gas to the gas pipeline through the purge pipe 16, thereby achieving a purge effect, that is, using an external safety gas to purge the gas pipeline. Generally, the gas used for purging is nitrogen.

[0033] Reference Figure 1 and Figure 2The data detection system 2 includes a gas concentration detection device 22, a first pressure detection device 23 and a second control module 24. The gas concentration detection device 22 and the first pressure detection device 23 are both installed on the gas storage box 13, and the gas concentration detection device 22 and the first supervision detection device are both electrically connected to the second control module 24.

A pressure threshold interval is set in the detection management platform 3. When the pressure value detected by the first pressure sensor is outside the pressure threshold interval, it indicates that there is a blockage or leakage, and the alarm prompt module 33 issues an alarm prompt.

[0035] The implementation principle of a residual gas detection system for a gas pipeline in an embodiment of the present application is as follows: close the first control switch 14 and open the second control switch 15, so that the first connecting pipeline 11 is closed, and gas is added by blowing the pipeline 16. The staff determines whether the connection between the second connecting pipeline 12 and the gas pipeline is blocked according to the detection results of the first pressure detection device 23 and the third pressure detection device 26 displayed on the data display module 34, close the second control switch 15 and open the first control switch 14, so that the second connecting pipeline 12 is closed, and gas is added by blowing the pipeline 16. The staff determines whether the connection between the first connecting pipeline 11 and the gas pipeline is blocked according to the detection results of the first pressure detection device 23 and the second pressure detection device 25 displayed on the data display module 34, and closes the first control switch 14 and the second control switch 15 at the same time, so that both connecting pipelines are in a closed state, and determines whether the first control switch 14 and the second control switch 15 are leaking according to the detection results of the first pressure detection device 23 displayed on the data display module 34. In the case of both being negative, when the detected gas concentration is higher than the safety value, the staff performs ventilation blowing through the blowing pipeline 16.
