Embodiment
The utility model is further described below in conjunction with the accompanying drawings, the scope of protection of the utility model be not limited to
It is lower described：
As shown in figure 1, a kind of Full-automatic drainage gas recovery facility, it includes controller, natural gas compressor 1, nitrogen compression
Machine 2, knockout drum 3 and the closure 5 for being fixedly arranged on the top of gas well 4, the described top of closure 5 are provided with joint 6 and connected
Ventilate the centre bore of well 4, be installed with delivery pipe 7 in centre bore, 7 vertical setting of delivery pipe, the bottom of delivery pipe 7 extends gas
In well 4, the upper end of delivery pipe 7 is extended outside gas well 4, and inlet 8 and row are provided with the side wall of described knockout drum 3
Liquid mouth 9, inlet 8 are connected with the upper end of delivery pipe 7, and high-pressure pump 10 is connected with leakage fluid dram 9, and the top of knockout drum 3 is set
Gas outlet 11 is equipped with, gas outlet 11 is connected with the arrival end of natural gas compressor 1, and blast pipe is provided with natural gas compressor 1
12, chuck 13 is cased with blast pipe 12, and the gas outlet of described nitrogen compressor 2 is connected with joint 6；Described knockout drum
High level sensor 14 and low liquid level sensor 15 are provided with 3, high level sensor 14 is located at the lower section of inlet 8, described
High level sensor 14, low liquid level sensor 15 and high-pressure pump 10 be connected with controller.
Described controller is PLC, and controller is connected with natural gas compressor 1 and nitrogen compressor 2, passes through control
