Description

Technical Field

[0001] The utility model relates to the technical field of associated gas recovery, in particular to an associated gas recovery device. Background Art

[0002] Associated gas usually refers to natural gas that coexists with petroleum. According to the theory of oil generation from organic hydrocarbons, organic matter can evolve into liquid hydrocarbons and gaseous hydrocarbons. Gaseous hydrocarbons are either dissolved in liquid hydrocarbons or exist in the upper part of oil and gas reservoirs in the form of gas caps. Both types of gaseous hydrocarbons are called oilfield associated gas or associated gas. From the perspective of oil production, it refers to the natural gas produced when exploiting oil fields or oil reservoirs.

[0003] At present, in the process of associated gas recovery, the associated gas is transported to the associated gas recovery device for recovery and treatment. The existing associated gas contains a large amount of water vapor. If the associated gas is burned in the recovery device, a large amount of water vapor will affect the combustion of the associated gas. At the same time, a catalyst is built into the associated gas recovery device. Water vapor will also block the honeycomb carrier purification catalyst in the catalyst and reduce the purification performance of the catalyst. Therefore, we propose an associated gas recovery device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Refer to Figures 1-3 , an associated gas recovery device, including an associated gas storage tank 1, an associated gas recovery device body 2, and a sealed recovery box 3 fixedly arranged on the top of the associated gas storage tank 1 and communicated with its air outlet pipe. The bottom of the associated gas recovery device body 2 and the top of the sealed recovery box 3 are connected through a connecting pipe 4. A through hole communicated with the connecting pipe 4 is opened at the top of the sealed recovery box 3, and the sealed recovery box 3 can collect condensed water;

[0020] A condensed water inlet pipe 5 and a condensed water outlet pipe 6 are fixedly connected to the inner side wall of the sealed recovery box 3. The condensed water inlet pipe 5 is connected with a condensed liquid production machine. The condensed liquid can be transported in the condensed water inlet pipe 5. The condensed liquid production machine is not shown in the figure. This is the prior art and will not be elaborated here. A plurality of first bent connecting pipes 7 and a plurality of second bent connecting pipes 8 are respectively fixedly connected to the outer side walls of the condensed water inlet pipe 5 and the condensed water outlet pipe 6. The first bent connecting pipes 7 and the second bent connecting pipes 8 on the same side are connected through an inclined ultra-thin metal water delivery pipe 9. The distance between adjacent two inclined ultra-thin metal water delivery pipes 9 is the same. The position of the inclined ultra-thin metal water delivery pipe 9 is as Figure 1 shown. The purpose of the inclined ultra-thin metal water delivery pipe 9 being inclined is to facilitate the condensed water attached to the inclined ultra-thin metal water delivery pipe 9 to flow and concentrate in the sealed recovery box 3 for accumulation;

[0021] A same collection box 10 is fixedly connected to the outer side walls of a plurality of inclined ultra-thin metal water delivery pipes 9. A plurality of mounting holes are opened on the outer side wall of the collection box 10. The outer side wall of the inclined ultra-thin metal water delivery pipe 9 on the same side is fixedly connected to the inner side wall of the mounting hole. A conical metal liquid collection block 11 is fixedly sleeved on the outer side wall of the inclined ultra-thin metal water delivery pipe 9 located in the collection box 10. The conical metal liquid collection block 11 is convenient for the concentration of condensed water. A drain pipe 12 communicated with it is fixedly connected to the outer side wall of the collection box 10. Two partition plates 13 are fixedly connected to the inner side wall of the sealed recovery box 3;

[0022] A condensate increasing device is arranged on the outer side wall of the inclined ultra-thin metal water delivery pipe 9. The condensate increasing device includes a plurality of fixing holes 14 opened on the outer side wall of the inclined ultra-thin metal water delivery pipe 9. Adjacent two fixing holes 14 are connected through a U-shaped metal pipe 15. A plurality of flow dividing blocks 16 are fixedly connected to the inner side wall of the inclined ultra-thin metal water delivery pipe 9. The position of the flow dividing blocks 16 is as Figure 2As shown, the function of the flow splitting block 16 is to facilitate the condensate to enter the fixing holes 14 and the U-shaped metal pipes 15 when the condensate moves in the inclined ultra-thin metal water delivery pipe 9. The distance between two adjacent U-shaped metal pipes 15 is the same as the distance between two adjacent flow splitting blocks 16. Vertically, the flow splitting block 16 is located directly below the U-shaped metal pipe 15.

[0023] The functional principle of the present utility model can be elaborated through the following operation method: During the process of the associated gas storage tank 1 delivering the associated raw gas to the associated gas recovery device body 2, the outlet pipe of the associated gas storage tank 1 will deliver the associated raw gas into the sealed recovery box 3, and the condensed water will be transported through the condensed water inlet pipe 5 and the first bent connecting pipe 7 to the inclined ultra-thin metal water delivery pipe 9, and then discharged through the inclined ultra-thin metal water delivery pipe 9, the second bent connecting pipe 8 and the condensed water outlet pipe 6;

[0024] Meanwhile, when the condensed water passes through the inclined ultra-thin metal water delivery pipe 9, the condensed water will enter the fixing holes 14 and the U-shaped metal pipes 15 through the flow splitting block 16, and the above process is repeated until all the U-shaped metal pipes 15 are transporting condensed water. When the condensed water passes through the inclined ultra-thin metal water delivery pipe 9 and the U-shaped metal pipes 15, it will cool the outer walls of the inclined ultra-thin metal water delivery pipe 9 and the U-shaped metal pipes 15, which causes the water vapor in the associated raw gas to adhere to the outer walls of the inclined ultra-thin metal water delivery pipe 9 and the U-shaped metal pipes 15 and condense, thus forming condensed water on the outer walls of the inclined ultra-thin metal water delivery pipe 9 and the U-shaped metal pipes 15. The condensed water located on the outer wall of the U-shaped metal pipe 15 will flow onto the inclined ultra-thin metal water delivery pipe 9;

[0025] Due to the inclined setting of the inclined ultra-thin metal water delivery pipe 9, the condensed water located on the inclined ultra-thin metal water delivery pipe 9 will flow into the collection box 10 through the conical metal liquid collection block 11 for accumulation. Finally, the condensed water in the collection box 10 will be discharged through the drain pipe 12, and the associated raw gas after discharging the water vapor will enter the associated gas recovery device body 2 for recovery until all the associated raw gas is processed.

[0026] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
