The units are connected by pipelines, which are complex to manufacture, poorly unified, occupy a large space, and have a potential risk of water in the outlet sample gas (refer to Figure 1 ). Therefore, it is urgent to develop a standard integrated gas lift tank that integrates extraction, pressure stabilization and cooling. Utility Model Content

[0027] The following is combined with Figure 2 This application is described in further detail.

[0028] The embodiment of the present application discloses an integrated gas lift tank.

[0029] Reference Figure 2 An integrated gas lift tank includes a tank body 1. In a feasible embodiment, the tank body 1 can be a columnar tank body 1 of any shape. As a preferred embodiment, in this embodiment, the tank body 1 is cylindrical, the tank body 1 is 700 mm high, and the outer diameter is 60 mm. A cooling chamber 2 and a separation chamber 3 are provided in the tank body 1. The separation chamber 3 is located below the cooling chamber 2 and is not connected to each other. A gas pipe 4 for guiding the separated gas out of the separation chamber 3 is penetrated in the cooling chamber 2, so that the gas lift tank occupies a smaller system space, reduces the size of the system cabinet, saves the cabinet cost, and facilitates the user's on-site installation.

[0030] Reference Figure 2In a further embodiment, a gas-liquid mixing inlet 5 and a sewage outlet 6 connected to the separation chamber 3 are integrally formed on the bottom wall of the tank body 1, and a guide pipe 7 connected to the gas-liquid mixing inlet 5 is installed in the tank body 1; an overflow port 8 connected to the separation chamber 3 is integrally formed on the outer wall of the tank body 1, and the overflow port 8 is arranged on the side of the separation chamber 3 close to the cooling chamber 2, and a pressure-stabilizing liquid sealing pipe 9 connected to the overflow port 8 is installed in the tank body 1, and the pressure-stabilizing liquid sealing pipe 9 extends to the bottom of the separation chamber 3, and the guide pipe 7 extends upward in a direction close to the cooling chamber 2, and the height of the upwardly extending end is lower than the height of the overflow port 8, and a cold air inlet 10 is integrally formed on the outer wall of the tank body 1 on the side of the cooling chamber 2 away from the separation chamber 3;

[0031] In a further embodiment, a 1 / 4NPT internal thread for installing a terminal joint is provided in the gas-liquid mixing inlet 5, a 1 / 2 internal thread for installing a sewage pipe is provided in the sewage outlet 6, a 1 / 2 external thread for installing an overflow pipe is provided on the outer wall of the overflow port 8, and a 1 / 4 external thread for connecting to an external cold air source is provided on the outer wall of the cold air inlet 10.

[0032] Reference Figure 2 In a further embodiment, a gas outlet 11 is provided on the top wall of the tank body 1. In this embodiment, the gas outlet 11 is welded by a 3 / 8 ferrule, the gas pipe 4 is a 3 / 8 pipe, the gas outlet 11 and the gas pipe 4 are coaxially arranged with the tank body 1, one end of the gas pipe 4 extends into the separation chamber 3, and the other end of the gas pipe 4 is adapted to be connected with the gas outlet 11 to conduct the extraction of the separated gas.

[0033] Reference Figure 2 In a further embodiment, a heat-insulating layer 12 is installed on the inner wall of the cooling chamber 2, and the heat-insulating layer 12 is wrapped around the outer periphery of the gas pipe 4 to improve the cooling efficiency.

[0034] The implementation principle of an integrated air lift tank in the embodiment of the present application is:

[0035] The original assembled gas lift device is complicated to assemble, and the units are connected by pipes, which has poor aesthetics and consistency. As a molded product, the integrated gas lift tank has high consistency and simple and beautiful layout. At the same time, the integrated gas lift tank integrates three independent tanks 1 into one tank, which can occupy a smaller system space, reduce the size of the system cabinet, save cabinet costs, and facilitate on-site installation by users.

[0036] The sample liquid of the original gas lift device enters from the top of the extraction tank and is mixed with nitrogen in the middle of the tank with a filler. When the sample liquid flow rate is high, it is easy to get clogged at the filler, causing the liquid to be unable to be discharged but to be discharged from the top with the gas, affecting the normal operation of the subsequent surface process and even risking the liquid being brought into the instrument. The sample water of the integrated gas lift tank enters from the bottom of the tank and is discharged through the pressure-stabilizing liquid seal tube 9, so that the liquid will not be discharged from the upper gas port, ensuring the safety of the subsequent process.

[0037] The gas separated from the separation tank has a high water content. The gas outlet 11 of the separation tank of the original gas lift device is connected to the cooling tank by a pipeline. Condensate is easy to appear in the pipeline. Because the pipeline is long, curved and sloped, it is easy to block the pipeline. The condensate is not easy to discharge and it is easy to cause fluctuations in gas flow. The integrated gas lift tank directly enters the condensation chamber from the separation chamber 3 for cooling. The pipeline is short, the inner diameter is large, and it is a vertical pipeline. The formed condensate can be directly and automatically discharged to the lower separation chamber 3.

[0038] The original cooling tank middle gas outlet 11 pipe is a double-layer structure with a small gap inside the pipe. The condensate produced during the cooling process will be adsorbed on the pipe wall or enter the instrument with the gas. The cooling part of the integrated tank uses a single-layer pipe with a large space, and the condensate produced during the cooling process can easily flow down to the separation chamber 3.

[0039] The original assembled gas lift device is difficult to achieve complete consistency in layout, pipeline direction, and pipeline length during system assembly. Inconsistency in manufacturing will cause uncertainty in product extraction effect, cooling effect, pressure stability and other performance. As a standard product, the integrated gas lift tank is fully integrated in one tank with complete consistency, and its various performances are also completely consistent, which is more convenient in project application and easy to monitor and improve its various indicators.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
