Description

Technical Field

[0001] This utility model relates to the field of desulfurization technology, and in particular to a multi-stage separation device for desulfurization of trial production gas. Background Technology

[0002] After drilling and completion, gas wells need to undergo gas testing and production testing to obtain dynamic data of the gas reservoir and understand the characteristics of the gas reservoir as early as possible. The data obtained from gas testing and production testing are used to analyze the production capacity of the gas well, determine the reasonable production capacity of a single well, and carry out the production of the gas field. In order to ensure that the tail gas emission standards are met, the produced gas needs to undergo multi-stage desulfurization and separation treatment.

[0003] Existing methods typically require multiple desulfurization tanks, allowing waste gas to pass through them sequentially for multi-stage treatment. This multi-stage treatment requires a lot of equipment, resulting in high waste gas treatment costs and a large space requirement.

[0004] Therefore, we propose a multi-stage separation device for desulfurization of pilot-produced gas to solve the problems in the background technology.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-stage separation device for desulfurization and recovery of trial-produced gas.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A multi-stage separation device for desulfurization of pilot-produced gas includes a base plate, a round rod, and a drive mechanism;

[0009] A desulfurization tank is mounted on the base plate. A round rod is rotatably connected to the desulfurization tank. A driving mechanism is located at the top of the desulfurization tank and is connected to the round rod. The round rod has two cavities, and multiple air inlets are connected to the cavities. An exhaust pipe is sealed to the round rod, and one end of each exhaust pipe extends into the cavities. A partition plate is sealed inside the desulfurization tank. Both the first and second baffles are rotatably connected to the round rod. Through the coordinated design of the desulfurization tank, the round rod, the first and second baffles, the first and second exhaust pipes, the baffles, and the drive mechanism, not only can multi-stage desulfurization of the exhaust gas be achieved, but also the primary, secondary, and tertiary desulfurization liquids can be stirred and agitated. This increases the chemical reaction time between the gas and the primary, secondary, and tertiary desulfurization liquids, thereby further improving the desulfurization effect on the gas. Moreover, the structure is simple and saves cost and space.

[0010] Preferably, the partitions one and two are arranged alternately with the cavities one and two. The partition one is located between the plurality of air inlets one and the exhaust pipe one, and the partition two is located between the plurality of air inlets two and the exhaust pipe two. Through the action of the partitions one and two, the desulfurization tank can be divided into multiple stages.

[0011] Preferably, multiple baffles are fixedly installed on the round rod, and the multiple baffles are arranged alternately with the first and second partitions. The round rod drives the multiple baffles to rotate synchronously, and the multiple baffles respectively turbulent and agitate the primary desulfurization liquid, the secondary desulfurization liquid and the tertiary desulfurization liquid, thereby increasing the chemical reaction time between the gas and the primary desulfurization liquid, the secondary desulfurization liquid and the tertiary desulfurization liquid, thereby further improving the desulfurization effect on the gas.

[0012] Preferably, the driving mechanism includes a motor, a gear, and a gear ring.

[0013] Preferably, the desulfurization tank is sealed with an air inlet pipe located below the first partition. The air inlet pipe delivers the gas to be desulfurized to the primary desulfurization liquid between the desulfurization tank and the first partition. The desulfurization tank is sealed with multiple liquid exchange pipes, which are arranged alternately with the first and second partitions. The multiple liquid exchange pipes facilitate the replacement of the primary, secondary, and tertiary desulfurization liquids.

[0014] Preferably, the top of the desulfurization tank is provided with an exhaust pipe three, and valves are provided on each of the multiple liquid exchange pipes. One-way valves are provided on the air inlet pipe, exhaust pipe one and exhaust pipe two.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a multi-stage separation device for desulfurization and recovery of trial production gas, referring to... Figure 1-5 A multi-stage separation device for desulfurization of pilot-produced gas includes a base plate 1, a round rod 3, and a drive mechanism;

[0027] A desulfurization tank 2 is mounted on a base plate 1. A round rod 3 is rotatably connected to the desulfurization tank 2. A driving mechanism is located on the top of the desulfurization tank 2 and is connected to the round rod 3. The round rod 3 has a cavity 5 and a cavity 8, and multiple air inlets 6 and 9, which are respectively connected to cavities 5 and 8. An exhaust pipe 7 and an exhaust pipe 10 are sealed and connected to the round rod 3. One end of the exhaust pipe 7 and the exhaust pipe 10 extends into cavities 5 and 8, respectively. A partition 11 and a partition 12 are sealed and connected inside the desulfurization tank 2. Both baffle 11 and baffle 2 12 are rotatably connected to the round rod 3. Through the coordinated design of the desulfurization tank 2, the round rod 3, baffle 11, baffle 2 12, exhaust pipe 1 7, exhaust pipe 2 10, baffle 13 and drive mechanism, not only can the multi-stage desulfurization effect of the exhaust gas be achieved, but also the turbulence and stirring of the first-stage desulfurization liquid, the second-stage desulfurization liquid and the third-stage desulfurization liquid can be realized. This increases the chemical reaction time between the gas and the first-stage desulfurization liquid, the second-stage desulfurization liquid and the third-stage desulfurization liquid, thereby further improving the desulfurization effect of the gas. Moreover, the structure is simple and saves cost and space.

[0028] See attached document Figure 2 The partitions 11 and 12 are arranged alternately with the cavities 5 and 8. The partition 11 is located between the multiple air inlets 6 and the exhaust pipe 7, and the partition 12 is located between the multiple air inlets 9 and the exhaust pipe 10. Through the action of the partitions 11 and 12, the desulfurization tank 2 can be divided into multiple stages. The air inlets 6 and 9 are both higher than the desulfurization liquid level. Moreover, the circular rod 3 drives the multiple baffles 13 to rotate at a relatively slow speed, and the desulfurization liquid level is flush with the top of the baffles 13, thereby preventing the desulfurization liquid from entering the air inlets 6 and 9.

[0029] See attached document Figure 2-4 Multiple baffles 13 are fixedly installed on the round rod 3. The multiple baffles 13 are arranged alternately with the first baffle 11 and the second baffle 12. The round rod 3 drives the multiple baffles 13 to rotate synchronously, and the multiple baffles 13 respectively turbulent and agitate the primary desulfurization liquid, the secondary desulfurization liquid and the tertiary desulfurization liquid, thereby increasing the chemical reaction time between the gas and the primary desulfurization liquid, the secondary desulfurization liquid and the tertiary desulfurization liquid, thereby further improving the desulfurization effect on the gas.

[0030] See attached document Figure 1-2 The drive mechanism includes a motor 14, a gear 15, and a gear ring 16. The motor 14 is fixedly installed on the top of the desulfurization tank 2. The output end of the motor 14 is fixedly connected to the gear 15. The gear ring 16 is meshed on the gear 15. The gear ring 16 is fixedly sleeved on the round rod 3 for driving the round rod 3.

[0031] See attached document Figure 1-2 The desulfurization tank 2 is sealed with an air inlet pipe 17, which is located below the partition 11. The air inlet pipe 17 is used to transport the gas to be desulfurized to the primary desulfurization liquid between the desulfurization tank 2 and the partition 11. The desulfurization tank 2 is sealed with multiple liquid exchange pipes 19, which are arranged alternately with the partition 11 and the partition 2 12. The multiple liquid exchange pipes 19 facilitate the replacement of the primary, secondary and tertiary desulfurization liquids. The top of the desulfurization tank 2 is equipped with an exhaust pipe 3 18. Valves are installed on the multiple liquid exchange pipes 19. One-way valves are installed on the air inlet pipe 17, exhaust pipe 1 7 and exhaust pipe 2 10. The multiple one-way valves can prevent the desulfurization liquid from flowing back into the air inlet pipe 17, exhaust pipe 1 7 and exhaust pipe 2 10.

[0032] See attached document Figure 2 A sealed bearing is fixedly sleeved on the round rod 3. The outer wall of the sealed bearing is fixedly connected to the desulfurization tank 2. A filter plate 4 is rotatably connected to the round rod 3. The filter plate 4 is fixedly connected to the desulfurization tank 2. Two sealed bearings are fixedly sleeved on the round rod 3. The outer walls of the two sealed bearings are fixedly connected to the partition plate 11 and the partition plate 12, respectively. The function of the sealed bearing and the two sealed bearings not only ensures the rotation of the round rod 3, but also prevents the leakage of waste gas, secondary desulfurization liquid and tertiary desulfurization liquid.

[0033] Working principle: First, the gas that needs to be desulfurized is transported to the primary desulfurization liquid between the desulfurization tank 2 and the baffle 11 through the air inlet pipe 17. Through the chemical reaction between the liquid and the gas, the gas is desulfurized in the first stage.

[0034] Then, under the action of air pressure, the gas enters the cavity 5 through multiple air inlets 6 on the round rod 3, and is discharged into the desulfurization liquid between the partition 11 and the partition 2 12 through the exhaust pipe 7 to carry out a chemical reaction, thereby achieving the effect of secondary desulfurization of the gas.

[0035] Subsequently, under the action of air pressure, the gas enters the cavity 8 through the multiple air inlets 9 on the round rod 3, and is discharged into the tertiary desulfurization liquid between the partition plate 12 and the filter plate 4 through the exhaust pipe 10 to carry out a chemical reaction, thereby achieving the effect of tertiary desulfurization of the gas.

[0036] Finally, the filter plate 4 can filter out harmful substances in the gas, thereby achieving further purification of the gas. Then, the purified gas is discharged through the exhaust pipe 18.

[0037] During the aforementioned gas desulfurization process, the electric motor 14 is started, which drives the gear 15 to rotate and transmit power to the gear ring 16. The gear ring 16 drives the round rod 3 to rotate on the desulfurization tank 2. At the same time, the round rod 3 drives multiple baffles 13 to rotate synchronously, causing the baffles 13 to turbulently agitate the primary, secondary, and tertiary desulfurization liquids, thereby increasing the chemical reaction time between the gas and the primary, secondary, and tertiary desulfurization liquids, and thus further improving the desulfurization effect of the gas.

[0038] The technological advancements of this invention compared to existing technologies are as follows: by coordinating various components, it is possible to achieve multi-stage desulfurization of waste gas without the need for multiple desulfurization devices. Moreover, the structure is simple, saves costs and space, and greatly enhances practicality.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
