Description

Technical Field

[0001] The invention relates to the technical field of natural gas desulfurization, and in particular to a natural gas desulfurization atomization device. Background Art

[0002] The process of removing acidic components such as sulfide from natural gas is called desulfurization. At the end of the 19th century, Britain began to use dry iron oxide to remove sulfide from gas flow, but it became an independent industrial branch after alcohol amine solvents were used in gas desulfurization in the 1930s. After nearly 80 years of development, nearly 100 desulfurization methods have been reported at home and abroad. According to weak acidity and strong reducibility, it can be divided into two categories: wet method and dry method. The wet method includes absorption method and wet oxidation method; the dry method includes iron oxide method, activated carbon method, zinc oxide method, etc.; and other desulfurization methods such as molecular sieve method, slurry desulfurization, membrane separation method, biochemical desulfurization, etc.

[0003] At present, the wet centralized desulfurization is mainly used in the natural gas desulfurization process, mainly based on the traditional amine method-Claus sulfur recovery and tail gas treatment process, which has good economic efficiency. However, when the traditional amine method is used to treat high carbon-sulfur ratio, low potential sulfur and remote dispersed sulfur-containing gas wells, due to its low sulfur content and the particularity of its geographical location, as well as the cost of pipeline gathering and transportation, the traditional amine centralized desulfurization treatment process is difficult to apply, which seriously affects the cost of natural gas development.

[0004] In order to make up 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 process principle is to directly convert hydrogen sulfide in natural gas into elemental sulfur or sulfide while desulfurizing, eliminating the subsequent sulfur recovery and tail gas treatment processes, thereby simplifying the process flow, facilitating operation, and reducing secondary environmental pollution.

[0005] Dry and wet natural gas desulfurization, because natural gas exists in gaseous form, cannot fully contact with solid or liquid reagents, which will greatly affect the treatment effect. In order to increase the contact area between natural gas and reagents, a desulfurization tower is usually required. However, due to the large size of the desulfurization tower, the desulfurization cost is high, the desulfurization efficiency is low, the equipment maintenance is difficult, and there are safety risks.

[0025] Figure 1 This is a schematic diagram of the natural gas desulfurization atomization device. Figure 1 As shown, and refer to Figures 2 to 3 The embodiment of the present invention provides a natural gas desulfurization atomization device, which includes a gas pipeline 100, an atomization mechanism 200 and a medicine supply mechanism. The gas pipeline 100 is used to transport natural gas, and the atomization mechanism 200 is connected to the gas pipeline 100, and is used to atomize the liquid desulfurizer and pass the atomized liquid desulfurizer into the gas pipeline 100. The medicine supply mechanism is connected to the atomization mechanism 200, and is used to pressurize the liquid desulfurizer and pass it into the atomization mechanism 200.

[0026] Specifically, the drug supply mechanism is used to store a large amount of liquid desulfurizer, so that the liquid desulfurizer can be continuously delivered to the atomizing mechanism 200. Furthermore, the setting of the drug supply mechanism to pressurize the liquid desulfurizer can make the liquid desulfurizer be delivered forward, and at the same time, the liquid desulfurizer in a high-pressure state can be more fully atomized under the action of the atomizing mechanism 200, thereby increasing the desulfurization effect of the desulfurizer on natural gas.

[0027] Specifically, the atomizing mechanism 200 can convert the liquid desulfurizer into an atomized state, thereby increasing the contact area between the desulfurizer and the natural gas, and thus greatly increasing the desulfurization effect on the natural gas. At the same time, the atomizing mechanism 200 can desulfurize the natural gas under normal circumstances, thereby simplifying the processing equipment, improving the desulfurization efficiency, and reducing the processing cost.

[0028] During operation, the desulfurized natural gas is introduced into the gas pipeline 100, and the drug supply mechanism and the atomizing mechanism 200 are started. The drug supply mechanism pressurizes the liquid desulfurizer and introduces it into the atomizing mechanism 200, and the atomizing mechanism 200 atomizes the liquid desulfurizer. The atomized sulfidizing agent is introduced into the gas pipeline 100, thereby desulfurizing the natural gas.

[0029] In some embodiments of the present invention, Figure 2As shown, the gas pipeline 100 includes a main pipeline 110, a sub-pipeline 120, a main ball valve 130 and two sub-ball valves 140. The sub-pipeline 120 is connected in parallel to the main pipeline 110 and communicates with the main pipeline 110. The atomizing mechanism 200 is detachably mounted on the sub-pipeline 120, and the sub-ball valves 140 are mounted on the sub-pipeline 120 and are located on both sides of the atomizing mechanism 200. The main ball valve 130 is mounted on the main pipeline 110 and is located between the two ends of the sub-pipeline 120.

[0030] Specifically, the main ball valve 130 is provided to control the opening and closing of the main pipeline 110, and the secondary ball valve 140 is used to control the opening and closing of the secondary pipeline 120. Further, the atomizing mechanism 200 is detachably provided, so that the atomizing mechanism 200 can be conveniently replaced and repaired. Further, under normal working conditions, the main ball valve 130 is closed, and the two secondary ball valves 140 are opened, so that the natural gas is only transported forward from the secondary pipeline 120, thereby ensuring that the atomized desulfurizer reacts with the natural gas. Further, when the atomizing mechanism 200 needs to be disassembled and replaced, the two secondary ball valves 140 are closed, the main ball valve 130 is opened, and the flow of natural gas in the secondary pipeline 120 is cut off, so that the natural gas only passes through the main pipeline 110. Therefore, the provision of the secondary pipeline 120 and the secondary ball valve 140 can prevent the leakage of natural gas when the atomizing mechanism 200 is replaced or repaired, and can also ensure that the natural gas is normally transported forward.

[0031] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the atomization mechanism 200 includes a drug feed pipe 210, a high-pressure spray nozzle 220 and a drug feed flange 230. The drug feed pipe 210 has a drug outlet at one end, which is located in the gas pipe 100, and a drug feed port at the other end, which is located outside the gas pipe 100. The drug feed flange 230 is fixedly arranged at the drug feed port of the drug feed pipe 210, and is used to be fixedly connected to the outlet of the drug supply mechanism. The high-pressure spray nozzle 220 is arranged at the drug outlet of the drug feed pipe 210.

[0032] Specifically, the drug inlet of the drug inlet pipeline 210 is connected to the drug supply mechanism. Further, the drug inlet flange 230 can increase the connection stability. Specifically, the direction of the high-pressure atomizing nozzle is set in the same direction as the flow direction of the natural gas, so that the atomized desulfurizing agent can flow along the flow direction of the natural gas. Further, the high-pressure atomizing nozzle can further pressurize and atomize the liquid sulfiding agent.

[0033] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the atomizing mechanism 200 further includes an atomizing housing 240. The atomizing housing 240 is in the shape of a three-way pipe, and the two ends of the atomizing housing 240 along the axial direction are flange-connected to two auxiliary ball valves 140. The medicine feeding pipeline 210 is inserted into the atomizing housing 240 from the other end thereof.

[0034] Specifically, the atomizing housing 240 is a right-angle three-way pipe, and the two ends along the axial direction are respectively connected to the two auxiliary ball valves 140 by flanges in a detachable manner, which can facilitate the disassembly of the atomizing housing 240. Furthermore, a flange is coaxially fixedly provided on the medicine feeding pipe 210, and the medicine feeding pipe 210 is detachably installed at the other end opening of the atomizing housing 240 through the flange, so that the medicine feeding pipe 210 and the high-pressure spray nozzle 220 can be easily disassembled from the atomizing housing 240.

[0035] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the drug supply mechanism includes a drug supply pipeline 310, a drug supply box 320 and a drug dosing metering pump 330. Liquid desulfurizer is stored in the drug supply box 320. One end of the drug supply pipeline 310 is connected to the drug dosing box, and the other end is fixedly connected to the drug inlet flange 230. The drug dosing metering pump 330 is arranged on the drug supply pipeline 310, and is used to measure the liquid desulfurizer in the drug supply pipeline 310 and control the flow rate of the liquid desulfurizer in the drug supply pipeline 310.

[0036] Specifically, the dosing metering pump 330 can adjust the flow rate of the desulfurizer in the drug supply pipeline 310 according to the demand for liquid desulfurizer. In this embodiment, a main switch valve is provided at the outlet of the drug supply box 320, and the inlet end of the drug supply pipeline 310 is connected to the drug supply box 320 through the main switch valve, and the main switch valve can control the opening and closing of the drug supply box 320.

[0037] In some embodiments of the present invention, Figure 1 As shown, the medicine supply mechanism also includes a damping valve 340. The damping valve 340 is arranged on the medicine supply pipeline 310, and is used to slow down the flow rate of the liquid desulfurizing agent in the medicine supply pipeline 310. Specifically, the damping valve 340 is of an airbag type, the main body is made of stainless steel, and the airbag is made of polytetrafluoroethylene. Furthermore, the setting of the damping valve 340 can increase the resistance to the flow of the liquid, thereby slowing down the flow rate of the liquid vulcanizing agent in the medicine supply pipeline 310, thereby reducing the kinetic energy of the liquid vulcanizing agent in the medicine supply pipeline 310, and can alleviate the pressure fluctuation in the medicine supply pipeline 310, prevent the medicine supply pipeline 310 from vibrating due to pressure fluctuations, and avoid the phenomenon that the nuts and other connectors on the medicine supply pipeline 310 are loosened due to vibration, thereby achieving the effect of protecting the pipeline and equipment.

[0038] In some embodiments of the present invention, Figure 1As shown, the drug supply mechanism also includes a pressure gauge 350. The pressure gauge 350 is arranged on the drug supply pipeline 310 to display the pressure in the drug supply pipeline 310. Specifically, the setting of the pressure gauge 350 can display the pressure in the drug supply pipeline 310 in real time, which is convenient for real-time observation and recording of the pressure data in the drug supply pipeline 310. In this embodiment, the pressure gauge 350 has a range of 0 to 10 MPa, is set to 5.2 MPa, and the drug dosing metering pump 330 stops working at the same time.

[0039] In some embodiments of the present invention, Figure 1 As shown, the drug supply mechanism further 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 desulfurizer to flow toward the drug inlet of the drug feed pipeline 210. Specifically, the one-way valve 360 ​​can prevent the liquid desulfurizer and / or natural gas from flowing back in the drug supply pipeline 310.

[0040] In some embodiments of the present invention, Figure 1 As shown, the drug supply mechanism further includes a safety valve 370. The safety valve 370 is disposed on the drug supply pipeline 310 and is used to open when the pressure in the drug supply pipeline 310 is higher than a preset pressure to release the pressure in the drug supply pipeline 310.

[0041] Specifically, the safety valve 370 is provided with a preset pressure value, which is the upper limit of the safety 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 relieve the pressure in the drug supply pipeline 310, thereby enabling the drug supply pipeline 310 to be maintained within the safety pressure, thereby protecting each component.

[0042] In some embodiments of the present invention, Figure 1 As shown, the drug supply mechanism further includes a back pressure pipe 380. One end of the back pressure pipe 380 is connected to the safety valve 370, and the other end is connected to the drug supply box 320. Specifically, when the safety valve 370 is opened, the liquid desulfurizer in the drug supply pipe 310 flows back to the drug supply box 320 through the back pressure pipe, thereby preventing the desulfurizer from being sprayed into the air and polluting the environment.

[0043] In some embodiments of the present invention, Figure 1 As shown, the medicine supply mechanism further includes two medicine supply ball valves 390, which are arranged on the medicine supply pipeline 310. The two medicine supply ball valves 390 are respectively arranged on both sides of the one-way valve 360, and the two ends of the one-way valve 360 ​​are respectively detachably connected to the two medicine supply ball valves 390. Specifically, the arrangement of the two medicine supply ball valves 390 can keep the one-way valve 360 ​​in a closed state when it is necessary to replace and repair the one-way valve 360, so that the maintenance and replacement of the one-way valve 360 ​​can be facilitated.

[0044] 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 its front and rear sides, so as to facilitate the maintenance and replacement of the corresponding components.
