Description

Technical Field

[0001] This utility model relates to the field of natural gas desulfurization technology, and in particular to a natural gas desulfurization atomization device. Background Technology

[0002] The process of removing acidic components such as sulfides from natural gas is called desulfurization. While Britain began using dry iron oxide methods to remove sulfides from gas streams in the late 19th century, it only became an independent industrial branch after the application of amine solvents in gas desulfurization in the 1930s. Over nearly 80 years of development, almost a hundred desulfurization methods have been reported both domestically and internationally. Based on their weak acidity and strong reducing properties, they can be divided into two main categories: wet and dry methods. Wet methods include absorption and wet oxidation; dry methods include iron oxide, activated carbon, and zinc oxide methods; and other desulfurization methods such as molecular sieve methods, slurry desulfurization, membrane separation, and biochemical desulfurization.

[0003] Currently, wet centralized desulfurization is the main method used in natural gas desulfurization, primarily employing the traditional amine-Claus sulfur recovery and tail gas treatment process, which offers good economic benefits. However, the traditional amine method is difficult to apply when treating high carbon-to-sulfur ratio, low latent sulfur, and remote, dispersed sulfur-containing gas wells. This is due to the low sulfur content, the unique geographical location of these wells, and the cost of pipeline transportation. Consequently, the traditional amine-based centralized desulfurization process is challenging to implement, significantly impacting the cost of natural gas development.

[0004] To compensate for the shortcomings of traditional natural gas desulfurization and purification processes, various dry and wet natural gas desulfurization and purification processes have emerged. The basic principle of these processes is to directly convert hydrogen sulfide and other substances in natural gas into elemental sulfur or sulfides during desulfurization, eliminating the need for subsequent sulfur recovery and tail gas treatment processes. This simplifies the process flow, facilitates operation, and reduces secondary environmental pollution.

[0005] Dry and wet natural gas desulfurization methods suffer from limitations. Since natural gas exists in a gaseous state, it cannot fully contact the solid or liquid desulfurizing agents, significantly impacting treatment efficiency. To increase the contact area between natural gas and the agents, atomizing devices are typically used to atomize the liquid desulfurizing agent before introducing it into the natural gas pipeline, allowing for thorough mixing and reaction. However, replacing or repairing existing atomizing devices requires shutting down the entire natural gas pipeline, significantly disrupting natural gas delivery. Furthermore, the replacement or repair of atomizing devices may pose a risk of gas leakage, reducing the safety of the work environment. Utility Model Content

[0039] Figure 1 This is a schematic structural diagram of a natural gas desulfurization atomization device, such as... Figure 1As shown, and with reference Figures 2 to 3 This utility model provides a natural gas desulfurization atomization device, which includes a gas pipeline 100, an atomization mechanism 200, and a chemical supply mechanism. The gas pipeline 100 includes a main pipeline 110, a secondary pipeline 120, a main ball valve 130, and two secondary ball valves 140. The secondary pipeline 120 is connected in parallel to and communicates with the main pipeline 110. The atomization mechanism 200 is detachably mounted on the secondary pipeline 120, and the secondary ball valves 140 are mounted on the secondary pipeline 120 and arranged sequentially along the length of the secondary pipeline 120.

[0040] The main ball valve 130 is installed on the main pipeline 110 and located between the two ends of the secondary pipeline 120. The atomizing mechanism 200 is installed on the secondary pipeline 120 and located between the two secondary ball valves 140. The atomizing mechanism 200 is used to atomize the liquid desulfurizing agent and introduce the atomized liquid desulfurizing agent into the secondary pipeline 120. The drug supply mechanism is connected to the atomizing mechanism 200 and is used to pressurize the liquid desulfurizing agent and introduce it into the atomizing mechanism 200.

[0041] Specifically, the main ball valve 130 controls the opening and closing of the main pipeline 110, while the auxiliary ball valve 140 controls the opening and closing of the auxiliary pipeline 120. Furthermore, the atomizing mechanism 200 is detachably configured, facilitating its replacement and maintenance. Furthermore, under normal operating conditions, the main ball valve 130 is closed, and both auxiliary ball valves 140 are open, thus ensuring that natural gas is only transported forward through the auxiliary pipeline 120, guaranteeing the reaction between the atomized desulfurizer and the natural gas. Furthermore, when the atomizing mechanism 200 needs to be disassembled and replaced, the two auxiliary ball valves 140 are closed, and the main ball valve 130 is opened, cutting off the flow of natural gas in the auxiliary pipeline 120, thus ensuring that natural gas only passes through the main pipeline 110. Therefore, the auxiliary pipeline 120 and the auxiliary ball valves 140 prevent natural gas leakage during the replacement or maintenance of the atomizing mechanism 200, while also ensuring the normal forward transport of natural gas, thereby increasing maintenance safety.

[0042] Specifically, the atomizing mechanism 200 converts the liquid desulfurizing agent into an atomized state, thereby increasing the contact area between the desulfurizing agent and natural gas, and thus greatly enhancing the desulfurization effect on natural gas. Simultaneously, the atomizing mechanism 200 can desulfurize natural gas under normal conditions, thereby simplifying processing equipment, improving desulfurization efficiency, and reducing processing costs.

[0043] During operation, the main ball valve 130 is closed and both auxiliary ball valves 140 are opened, allowing the desulfurized natural gas to flow forward through the auxiliary pipeline 120. The chemical supply mechanism and atomizing mechanism 200 are activated. The chemical supply mechanism pressurizes the liquid desulfurizing agent and introduces it into the atomizing mechanism 200, which atomizes the agent. The atomized desulfurizing agent is then introduced into the gas pipeline 100, thereby desulfurizing the natural gas. Furthermore, when the atomizing mechanism 200 needs replacement or maintenance, the two auxiliary ball valves 140 are closed and the main ball valve 130 is opened, preventing the natural gas to be desulfurized from entering the auxiliary pipeline 120 and allowing it to pass only through the main pipeline 110, thus facilitating the replacement or maintenance of the atomizing mechanism 200.

[0044] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, both auxiliary ball valves 140 are equipped with connecting flanges at one end of the atomizing mechanism 200. The atomizing mechanism 200 includes an atomizing component and an atomizing housing 240. The atomizing housing 240 is in the shape of a three-way pipe, and its two ends along the axial direction are detachably connected to the two auxiliary ball valves 140 via flanges. The atomizing component is connected to the drug supply mechanism and is disposed within the atomizing housing 240 from the other end of the atomizing housing 240.

[0045] Specifically, the atomizing housing 240 is a right-angle tee pipe, with both ends along the axial direction respectively connected to the flanges of two auxiliary ball valves 140, which facilitates the disassembly of the atomizing housing 240.

[0046] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the atomizing assembly includes a drug inlet pipe 210, a high-pressure spray nozzle 220, and a drug inlet flange 230. One end of the drug inlet pipe 210 is the drug outlet, located inside the gas pipeline 100, and the other end is the drug inlet, located outside the gas pipeline 100. The drug inlet flange 230 is fixedly installed at the drug inlet of the drug inlet pipe 210 for fixed connection with the outlet of the drug supply mechanism. The high-pressure spray nozzle 220 is located at the drug outlet of the drug inlet pipe 210.

[0047] Specifically, the drug inlet pipe 210 is inserted into the atomizing housing 240 from the other end, so that the drug outlet is located inside the atomizing housing 240 and the drug inlet is located outside the atomizing housing 240. Furthermore, a flange is coaxially fixed to the drug inlet pipe 210, and the drug inlet pipe 210 is detachably installed at the other end opening of the atomizing housing 240 via the flange, thereby facilitating the disassembly of the drug inlet pipe 210 and the high-pressure spray nozzle 220 from the atomizing housing 240.

[0048] In some embodiments of this utility model, such as Figure 2As shown, the chemical supply mechanism includes a chemical supply pipeline 310, a chemical supply tank 320, and a metering pump 330. The chemical supply tank 320 stores liquid desulfurizing agent. One end of the chemical supply pipeline 310 is connected to the chemical supply tank 320, and the other end is fixedly connected to the inlet flange 230. The metering pump 330 is installed on the chemical supply pipeline 310 and is used to supply the liquid desulfurizing agent in the chemical supply pipeline 310 and control the flow rate of the liquid desulfurizing agent in the chemical supply pipeline 310.

[0049] Specifically, the metering pump 330 can adjust the flow rate of the desulfurizing agent in the supply pipeline 310 according to the demand for liquid desulfurizing agent. In this embodiment, a main switch valve is provided at the outlet of the supply tank 320, and the inlet end of the supply pipeline 310 is connected to the supply tank 320 through the main switch valve, which can control the opening and closing of the supply tank 320.

[0050] In some embodiments of this utility model, such as Figure 2 As shown, the drug supply mechanism also includes a damping valve 340, which is installed on the drug supply pipeline to slow down the flow rate of the liquid desulfurizing agent in the drug supply pipeline 310. Specifically, the damping valve 340 is an airbag type, with a stainless steel body and a PTFE airbag. Furthermore, the damping valve 340 increases the resistance to liquid flow, thereby further slowing down the flow rate of the liquid desulfurizing agent in the drug supply pipeline 310, thus reducing the kinetic energy of the liquid desulfurizing agent in the drug supply pipeline 310. This helps alleviate pressure fluctuations in the drug supply pipeline and prevents the drug supply pipeline 310 from vibrating due to pressure fluctuations, thus avoiding loosening of nuts and other connecting parts on the drug supply pipeline 310 due to vibration, achieving the effect of protecting the pipeline and equipment.

[0051] In some embodiments of this utility model, such as Figure 2 As shown, the drug supply mechanism also includes a pressure gauge 350; the pressure gauge 350 is installed on the drug supply pipeline and is used to display the pressure inside the drug supply pipeline 310. Specifically, the pressure gauge 350 is designed to display the pressure inside the drug supply pipeline 310 in real time, facilitating real-time observation and recording of the pressure data inside the drug supply pipeline 310. In this embodiment, the pressure gauge 350 has a range of 0-10 MPa, is set to 5.2 MPa, and the drug metering pump 330 stops operating simultaneously.

[0052] In some embodiments of this utility model, such as Figure 2 As shown, the drug supply mechanism also includes a safety valve 370. The safety valve 370 is installed on the drug supply pipeline 310 and is used to open when the pressure in the drug supply pipeline 310 is higher than the preset pressure, so as to release the pressure in the drug supply pipeline 310.

[0053] Specifically, the safety valve 370 is set with a preset pressure value, which is the upper limit of the safe pressure value that the drug supply pipeline 310 and each component can withstand. Therefore, when the pressure in the drug supply pipeline 310 is higher than the preset pressure value, the safety valve 370 opens to release pressure in the drug supply pipeline 310, thereby keeping the pressure in the drug supply pipeline 310 within the safe range and thus protecting each component.

[0054] In some embodiments of this utility model, such as Figure 2 As shown, the drug supply mechanism also includes a back pressure pipe 380. One end of the back pressure pipe 380 is connected to a safety valve 370, and the other end is connected to a drug supply box 320.

[0055] Specifically, when the safety valve 370 is opened, the liquid desulfurizing agent in the supply pipeline 310 flows back to the supply tank 320 through the back pressure pipe, thereby preventing the desulfurizing agent from being sprayed into the air and polluting the environment.

[0056] In some embodiments of this utility model, such as Figure 2 As shown, the drug supply mechanism also includes a one-way valve 360. The one-way valve 360 ​​is disposed on the drug supply pipeline 310 and is used to allow the liquid desulfurizing agent and / or natural gas to flow towards the inlet of the drug supply pipeline 210. Specifically, the one-way valve 360 ​​prevents the liquid desulfurizing agent and / or natural gas from flowing back within the drug supply pipeline 310.

[0057] In some embodiments of this utility model, such as Figure 2 As shown, the drug supply mechanism also includes two drug supply ball valves 390; the drug supply ball valves 390 are disposed on the drug supply pipeline 310; the two drug supply ball valves 390 are respectively disposed on both sides of the one-way valve 360; the two ends of the one-way valve 360 ​​are detachably connected to the two drug supply ball valves 390 respectively. Specifically, the arrangement of the two drug supply ball valves 390 allows them to remain closed when the one-way valve 360 ​​needs to be replaced or maintained, thereby facilitating the maintenance and replacement of the one-way valve 360.

[0058] In some embodiments of the present invention, each component on the drug supply pipeline 310 can be provided with a drug supply ball valve 390 on both its front and rear sides to facilitate maintenance and replacement of the corresponding components.

[0059] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
