Embodiment 1

[0040] as Figure 1 As shown, the emergency working conditions of the present embodiment of the natural gas long-distance pipeline yard temporary treatment device, comprising a curved plate device 2, the arc plate device 2 and the opening on the gas pipeline 1 in conjunction, the arc plate device 2 is connected to the valve 3, the other end of the valve 3 is connected to the quick change joint 4; the other end of the quick change joint 4 is connected to the venting device 5 or nitrogen injection device 6 or bridging device 7, the other end of the bridging device 7 is connected to the other opening after the gas pipeline 1 crosses the blocked section.

[0041] In the gas shutdown maintenance, the venting device 5 is first connected to the quick change joint 4, so that most of the natural gas in the gas pipeline 1 is diverted to the flare device 54 is ignited. Then connect the nitrogen injection device 6 on the quick coupling 4, by injecting nitrogen into the gas pipeline 1, empty th...

Embodiment 2

[0052] A temporary treatment method for natural gas long-distance pipeline yard under emergency working conditions, including the following steps:

[0053] Air outage maintenance conditions:

[0054]S1: An opening hole is provided on the gas pipeline 1, the arc plate device 2 is connected at the opening of the gas pipeline 1, the valve 3 is connected on the curved plate device 2, the quick change joint 4 is connected at the other end of the valve 3, and the venting device 5 is connected on the quick change joint 4;

[0055] The venting device 5 includes an empty hose 51, a horizontal tube 52, a riser 53 and a flare device 54;

[0056] When connecting the venting device 5, the venting hose 51 is connected on the quick change joint 4, the horizontal tube 52 is connected at the other end of the venting hose 51, the riser 53 is connected at the other end of the horizontal pipe 52, and the flare device 54 is connected at the other end of the riser 53;

[0057] S2: open the valve 3, ign...

Abstract

The invention belongs to the technical field of oil and gas storage and transportation devices, and particularly relates to a temporary treatment device and method for a natural gas long-distance pipeline station yard under emergency working conditions. According to the technical scheme, the temporary treatment device for the natural gas long-distance pipeline station yard under the emergency working condition comprises an arc-shaped plate device, the arc-shaped plate device is matched with an opening in a gas conveying pipeline, a valve is connected to the arc-shaped plate device, and the other end of the valve is connected with a quick-change connector; the other end of the quick-change connector is connected with an emptying device or a nitrogen injection device or a bridging device, and the other end of the bridging device is connected to the other opening, crossing the blocking section, of the gas conveying pipeline. The invention provides a temporary treatment device and method for a natural gas long-distance pipeline station yard under an emergency working condition.

Description

Technical field [0001] The present invention belongs to the technical field of oil and gas storage and transportation device, specifically relates to a kind of emergency working conditions of natural gas long-distance pipeline station temporary treatment device and method. Background [0002] With the rapid development of China's natural gas pipeline construction, the pipelines and equipment in the station will inevitably encounter fire construction operations such as reconstruction and expansion, modernization, maintenance, and emergency repair. Natural gas long-distance pipeline yard is responsible for the production of oil and gas, and the fire operation often requires the station to stop the transmission or equipment to stop operation, so under the premise of ensuring the safety of the operation and the quality of construction, each process of the fire operation should save time as much as possible, and the fire operation process includes stopping the transmission and emptyin...
