Problems solved by technology
During the production process of coalbed methane wells, due to reasons such as failure to connect pipelines in time at the initial stage of drainage or failure of pipelines, and low gas production pressure, a part of the gas will be vented and burned. Some gas wells still use manual ignition when venting torches , very dangerous, and the cumulative amount of this part of the air is quite considerable, if recycling can bring certain economic and social benefits
In addition, with the expansion of the coalbed methane sector, the construction of pipeline infrastructure in new blocks lags behind, and the development of coalbed methane will inevitably face gathering and transportation problems

Embodiment 1
[0023] like figure 1 As shown, a low pressure coal layer air well is emptied to the recovery linkage, including the control system 5 and the automatic ignition system 1 and the recovery system 8 connected to the control system 5, wherein the automatic ignition system 1 is used for gas pressure. Leada does not receive the empty gas 7 when the recovery condition or the recovery system 8 needs to be repaired and combustion. The control system 5 is used to implement separate operation of the automatic ignition system 1 or the recovery system 8 based on the switching request. The recovery system 8 is used to separate moisture and impurities in the coalbed methane, boost or compress the coalbed methane. Thus the gas after recovery can enter the outer transmission line or the loading of the vehicle.
[0024] The automatic ignition system 1 includes a radiating valve 4, a damper valve 3, and a high-altitator 2, and the empty gas 7 is sealed by the high-altitator 2 after the vent valve 4 a...

The invention relates to a low-pressure coalbed methane well venting and recovery linkage device, which belongs to the technical field of coalbed methane recovery; it includes a control system and an automatic ignition system and a recovery system respectively connected to the control system, wherein the automatic ignition system is used when the gas production pressure is too high When the recovery condition cannot be met or the recovery system needs to be overhauled, the vented gas is ignited and burned; the control system is used to realize the independent operation of the automatic ignition system or the recovery system according to the switching request; the recovery system is used to separate the moisture and Impurities, pressurization or compression liquefaction of coalbed methane: the invention has the function of venting and recovery linkage, which can realize the mutual switching between automatic ignition and venting gas recovery, improve energy utilization efficiency and reduce environmental pollution.
Description
Technical field [0001] According to a low pressure coal layer air well, emptying and recycling linkage, belonging to the technical field of coalbed methane recovery. Background technique [0002] The emptying the torch system is an indispensable safety facility in the production of gas industries, which is the combustion gas in the event of normal production and the incident in the accident. During the production of coal seamless well production, since the piping is not in time, the pipeline failure is not in time, the gas pressure is too small, resulting in a part of the gas will be emptied, and some gas wells still use artificial ignition mode when leaving the torch , Very dangerous, and this partial air accumulation is considerable, and if recycling can bring certain economic and social benefits. In addition, as the coalbed metal plate expansion, the new block piping infrastructure is lagging, and the coalbed methane development will face the collection challenge. Therefore, i...
