Description

Technical Field

[0001] This utility model belongs to the field of desulfurization agent testing, specifically a pretreatment desulfurization agent testing device. Background Technology

[0002] During the drilling process in oilfield development, when encountering hydrogen sulfide formations, hydrogen sulfide can rapidly corrode drilling tools, severely affecting drilling efficiency. To prevent hydrogen sulfide pollution during drilling, desulfurizing agents are usually used for desulfurization. To ensure the quality of the desulfurizing agents, testing is then conducted.

[0003] In existing technologies, when testing desulfurizing agents, the sample is first taken out of the storage device and placed in a container. A diluent is then added to the container to dilute the sample. The diluted sample is then transferred to a gas chromatograph (GC), where the concentration of sulfides in the treated gas is analyzed to assess the desulfurization efficiency of the agent. However, in practice, because the sample is directly transferred to the GC without further processing, the composition of the sample becomes uneven, and particles or impurities in the sample can interfere with the analysis, thus reducing the accuracy and reliability of the analytical results.

[0004] In summary, this utility model provides a pretreatment desulfurizer detection device to solve the above problems. Utility Model Content

The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0022] Example 1

[0023] like Figure 1-5 As shown, this is the first embodiment of the present invention. This embodiment provides a pretreatment type desulfurizer detection device, including a tank 1. A tank cover 2 is movably connected to the top of the tank 1. A connecting cylinder 3 is fixedly connected to the bottom of the tank cover 2. A ceramic filter 4 and a polymer filter 5 are threadedly connected to the upper and lower ends of the inner cavity of the connecting cylinder 3, respectively. The ceramic filter 4 and the polymer filter 5 are fixedly connected by a connecting rod. A pH sensor 6 is fixedly connected to the bottom of the inner cavity of the tank 1. A motor 7 is fixedly connected to the bottom of the tank 1. The output shaft of the motor 7 extends into the inner cavity of the tank 1 and is driven by a stirring blade 8. An exhaust pipe 9 is connected to the top of the tank cover 2. An ozone filter 10 and an activated carbon adsorption screen 11 are fixedly connected to the upper and lower ends of the inner cavity of the exhaust pipe 9, respectively.

[0024] like Figure 1-5As shown, tank 1 provides space for desulfurizer pretreatment. When the desulfurizer and diluent pass through ceramic filter 4 and polymer filter 5, the ceramic filter 4 and polymer filter 5 filter and intercept impurities in the desulfurizer and diluent, effectively preventing impurities from interfering with the quality of subsequent testing. The ceramic filter 4 and polymer filter 5 are threadedly connected to the connecting cylinder 3, which facilitates the disassembly and cleaning of the ceramic filter 4 and polymer filter 5. They can be reused without affecting the filtration accuracy. As the diluent and desulfurizer fall to the bottom of the inner cavity of tank 1, the output shaft of motor 7 drives the stirring blade 8 to rotate. The rotation of stirring blade 8 can improve the dilution efficiency and make the components in the desulfurizer evenly distributed, which can improve the accuracy of subsequent testing. The pH sensor 6 can detect the acidity and alkalinity of the solution in real time, making it easy to know whether the desulfurizer is within the effective requirements.

[0025] Example 2

[0026] Reference Figure 1 and 5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0027] In this embodiment, the top of the exhaust pipe 9 is threadedly connected to the cylinder cover 12, both sides of the top of the tank cover 2 are connected to the liquid inlet pipe 13, the lower end of the front of the tank body 1 is connected to the liquid delivery pipe 14, and the other end of the liquid delivery pipe 14 is connected to an external gas chromatograph.

[0028] A fixing sleeve 15 is fixedly connected to the surface of the tank body 1, and a support frame 16 is fixedly connected to the surface of the fixing sleeve 15. A microcontroller 17 is fixedly connected to the front of the fixing sleeve 15, and a display screen is provided on the front of the microcontroller 17.

[0029] The output of the microcontroller 17 is connected to the display screen and the input of the motor 7, respectively, and the output of the PH sensor 6 is connected to the input of the motor 7.

[0030] like Figure 1 and 5 As shown, the exhaust pipe 9 can be sealed by the cylinder cover 12 to prevent external impurities from entering the interior of the exhaust pipe 9. The desulfurizing agent and diluent can be transferred through the liquid inlet pipe 13 to facilitate their entry into the inner cavity of the connecting cylinder 3. The treated desulfurizing agent can be transferred to the gas chromatograph for detection through the liquid delivery pipe 14. The tank body 1 can be stably supported by the fixing sleeve 15 and the support frame 16 to ensure its stability during use. The motor 7 can be controlled by the microcontroller 17, and the detection data of the pH sensor 6 can be received at the same time.

[0031] Example 3

[0032] Reference Figure 1-3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0033] In this embodiment, a first magnetic ring 18 is fixedly connected to the bottom of the connecting cylinder 3, and a second magnetic ring 19 is fixedly connected to the upper end of the inner cavity of the tank body 1. The bottom of the first magnetic ring 18 is in contact with the top of the second magnetic ring 19, and the first magnetic ring 18 and the second magnetic ring 19 are magnetically connected.

[0034] The connecting cylinder 3 is located in the inner cavity of the tank body 1 and is movably connected to the inner cavity of the tank body 1. A sealing ring 20 is fixedly connected to the bottom of the tank cover 2 and on the surface of the connecting cylinder 3. The bottom of the sealing ring 20 is in contact with the top of the tank body 1.

[0035] like Figure 1-3 As shown, the can lid 2 drives the connecting cylinder 3 and the sealing ring 20 to move downwards. The connecting cylinder 3 will enter the inner cavity of the can body 1, and the sealing ring 20 will contact the can body 1, thus sealing the connection between the can lid 2 and the can body 1. At the same time, the connecting cylinder 3 drives the first magnetic ring 18 to contact the second magnetic ring 19, so that the two are magnetically connected, thereby ensuring the firmness of the connection.

[0036] In use, the desulfurizing agent and diluent are first transferred to the inner cavity of the connecting cylinder 3 through the inlet pipe 13. The desulfurizing agent and diluent then pass through the ceramic filter screen 4 and the polymer filter screen 5. These filters effectively intercept impurities in the desulfurizing agent and diluent, preventing them from interfering with subsequent testing. The ceramic filter screen 4 and polymer filter screen 5 are threadedly connected to the connecting cylinder 3, facilitating disassembly and cleaning. They are reusable without affecting filtration accuracy. The filtered diluent and desulfurizing agent then fall to the bottom of the inner cavity of the tank 1. The microcontroller 17 then activates the motor 7, and the output shaft of the motor 7... The stirring blade 8 rotates, which improves the dilution efficiency and ensures uniform distribution of the desulfurizing agent's components, thus enhancing the accuracy of subsequent testing. During the mixing process, the pH sensor 6 detects the solution's acidity and alkalinity in real time and transmits the data to the microcontroller 17. The microcontroller 17 analyzes the data and displays it on a screen, allowing personnel to easily understand whether the desulfurizing agent is within the effective threshold. The diluted desulfurizing agent is then transferred to an external gas chromatograph via the infusion tube 14. Finally, the gas chromatograph analyzes the concentration of sulfides in the treated gas to evaluate the desulfurization efficiency of the desulfurizing agent.
