Abstract
Description
Technical Field
[0001] This utility model relates to the field of desulfurization tower technology, and in particular to a high-efficiency desulfurization tower for sulfur-containing natural gas. Background Technology
[0002] Natural gas refers to all gases that exist naturally in the world, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere. However, the commonly used definition of "natural gas" is a narrower one from an energy perspective, referring to a mixture of hydrocarbon and non-hydrocarbon gases naturally occurring in underground strata, including oilfield gas, gas field gas, coalbed methane, mud volcano gas, and biogenic gas, with small amounts also found in coal seams. Natural gas is mainly composed of methane and small amounts of ethane, propane, nitrogen, and butane. It is primarily used as fuel and also as a raw material for manufacturing chemicals such as acetaldehyde, acetylene, ammonia, carbon black, ethanol, formaldehyde, hydrocarbon fuels, hydrogenated oils, methanol, nitric acid, syngas, and vinyl chloride. Therefore, natural gas is a high-quality fuel and chemical raw material. During natural gas extraction, desulfurization towers are used to remove sulfur, thereby ensuring transportation safety, improving combustion efficiency, reducing environmental pollution, and protecting equipment and catalysts.
[0003] Chinese patent CN217103770U discloses a high-efficiency desulfurization tower for sulfur-containing natural gas, belonging to the technical field of natural gas desulfurization equipment. It includes a tower body and an inlet pipe. The inlet pipe is located at the bottom of one side wall of the tower body, and a Roots blower is installed on the inlet pipe. A rotating shaft is located inside the tower body, directly opposite the inlet pipe. A baffle is circumferentially fixed on the outer wall of the rotating shaft, and a through hole is provided on the baffle. A screen is installed in the middle of the tower body. This application designs an automatic cleaning mechanism consisting of an air pump, an air guide pipe, a solenoid valve, and a one-way valve. After desulfurization, the solenoid valve is activated. Because the one-way valve makes the liquid flow in the inlet pipe unidirectional, the high-pressure gas generated by the air pump enters the spray pipe through the air guide pipe, thereby applying pressure to the residual desulfurization liquid in the spray pipe and causing it to be completely discharged. This prevents waste of desulfurization liquid and avoids blockage caused by solidification of the desulfurization liquid in the spray pipe and spray nozzles, ensuring the subsequent spraying effect of the device and improving the functionality of the device.
[0004] However, the aforementioned patent can only clean the spray pipes and nozzles to prevent them from becoming clogged, but it cannot clean the inner wall of the tower. This results in a large amount of impurities adhering to the inner wall of the tower after long-term use, which in turn affects the desulfurization efficiency of natural gas. Utility Model Content
[0005] The purpose of this utility model is to provide a high-efficiency desulfurization tower for sulfur-containing natural gas, which solves the problem of the above-mentioned patent. During use, only the spray pipes and spray nozzles can be cleaned to avoid clogging. The inner wall of the tower cannot be cleaned, which leads to a lot of impurities adhering to the inner wall of the tower after long-term use, thus affecting the desulfurization efficiency of natural gas.
[0006] To achieve the above objectives, this utility model provides a high-efficiency desulfurization tower for sulfur-containing natural gas, comprising a tower body, wherein a fixing plate is fixedly connected between the lower sides of the front and rear side walls of the inner cavity of the tower body, and a motor is fixedly connected to the lower side of the right side wall of the tower body.
[0007] It also includes cleanup agencies;
[0008] The cleaning mechanism includes a rotating shaft, a first bevel gear, a mounting bracket, and a scraper. The rotating shaft is rotatably connected to the top center of the fixed plate. The first bevel gear is fixedly connected to the lower side of the outer wall of the rotating shaft. The mounting bracket is fixedly connected to the top of the rotating shaft. The scraper is fixedly connected to the left and right side walls of the mounting bracket.
[0009] The tower body has a spray frame fixedly connected to the upper inner wall, a high-pressure nozzle fixedly connected to the bottom of the spray frame, a water tank fixedly connected to the upper right side of the tower body, a water supply pipe fixedly connected to the top right side of the water tank, and a water pump fixedly connected to the top left side of the water tank. The water pump is connected to the water tank and the spray frame through a pipe.
[0010] The tower body has an air inlet on the lower side of its left side wall, a slag outlet at the bottom, and an air outlet at the top.
[0011] A spray pipe is fixedly connected to the upper side of the right side wall of the inner cavity of the tower body, and an atomizing nozzle is fixedly connected to the bottom of the spray pipe. A liquid inlet pipe is fixedly connected to the upper side of the left side wall of the tower body. The right end of the liquid inlet pipe passes through the tower body and extends into the inner cavity of the tower body, and the right end of the liquid inlet pipe is fixedly connected to the left end of the spray pipe.
[0012] The tower body has an installation shaft rotatably connected to the middle of the rear side wall of the inner cavity, and a dispersing blade is fixedly connected to the outer side wall of the installation shaft. The outer side wall of the dispersing blade has a through hole.
[0013] The motor's power output shaft is fixedly connected to a connecting shaft at its end. The end of the connecting shaft passes through the tower body and extends into the inner cavity of the tower body. A second bevel gear is fixedly connected to the end of the connecting shaft, and the second bevel gear meshes with the first bevel gear and rotates.
[0014] This utility model discloses a high-efficiency desulfurization tower for sulfur-containing natural gas. A water pump delivers clean water from a tank to a spray frame, where high-pressure nozzles spray the water onto the inner wall of the tower, rinsing it. A motor drives a connecting shaft, which in turn drives a second bevel gear, which in turn drives a first bevel gear, causing the rotating shaft to rotate. This rotating shaft then drives the mounting frame, causing scrapers to clean the inner wall of the tower. This device simultaneously brushes and rinses the inner wall, thoroughly removing impurities and preventing any impact on the desulfurization efficiency of the natural gas.
[0015] This utility model discloses a high-efficiency desulfurization tower for sulfur-containing natural gas. When the sulfur-containing natural gas enters the tower, it has a high flow velocity, which drives the dispersing blades. The dispersing blades then rotate along the mounting shaft, dispersing the sulfur-containing natural gas. Simultaneously, the dispersing blades, in conjunction with through holes, ensure that the sulfur-containing natural gas is evenly dispersed inside the tower. The desulfurization liquid is then transported to the spray pipe through the liquid inlet pipe, where atomizing nozzles spray the desulfurization liquid in a mist. Finally, the even dispersion of the sulfur-containing natural gas and the misting of the desulfurization liquid ensure sufficient contact between the sulfur-containing natural gas and the desulfurization liquid, thereby improving the desulfurization effect of the device and enhancing its overall performance.

Detailed Implementation
[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0024] Please see Figures 1-5A high-efficiency desulfurization tower for sulfur-containing natural gas includes a tower body 100. A fixing plate 200 is fixedly connected between the lower sides of the front and rear side walls of the inner cavity of the tower body 100. A motor 300 is fixedly connected to the lower side of the right side wall of the tower body 100. The tower body 100 also includes a cleaning mechanism, which includes a rotating shaft 210, a first bevel gear 220, a mounting frame 230, and a scraper 240. The rotating shaft 210 is rotatably connected to the top center of the fixing plate 200, and the rotating shaft 210 drives the mounting frame 230 to rotate. A first bevel gear 220 is fixedly connected to the lower side of the outer side wall of the rotating shaft 210. 0 is used to drive the rotating shaft 210 to rotate. A mounting bracket 230 is fixedly connected to the top of the rotating shaft 210. The mounting bracket 230 is used to install scraper 240. Scraper 240s are fixedly connected to the left and right side walls of the mounting bracket 230. Scraper 240s are used to clean the inner wall of the tower body 100. A spray frame 110 is fixedly connected to the upper side of the inner wall of the tower body 100. The spray frame 110 is used to install high-pressure nozzles 111. A high-pressure nozzle 111 is fixedly connected to the bottom of the spray frame 110. The high-pressure nozzle 111 is used to spray clean water to rinse the inner wall of the tower body 100. A mounting bracket 230 is fixedly connected to the upper side of the right side wall of the tower body 100. A water tank 120 is connected to the tower body 100. The water tank 120 is used to supply clean water to the side walls. A water inlet pipe 121 is fixedly connected to the top right side of the water tank 120. The water inlet pipe 121 is used to add clean water to the water tank 120. A water pump 130 is fixedly connected to the top left side of the water tank 120. The water pump 130 is used to transport the clean water in the water tank 120 to the spray frame 110. The water pump 130 is connected to the water tank 120 and the spray frame 110 through a pipe. The water pump 130 delivers the clean water in the water tank 120 to the spray frame 110, so that the high-pressure nozzles 111 spray clean water onto the inner wall of the tower body 100. The process involves flushing the inner wall of the tower body 100 with clean water, then driving the connecting shaft 310 to rotate via the motor 300. This, in turn, drives the second bevel gear 320 to rotate, which in turn drives the first bevel gear 220 to rotate. This, in turn, causes the rotating shaft 210 to rotate, which in turn drives the mounting bracket 230 to rotate. This allows the scraper 240 to clean the inner wall of the tower body 100. As a result, the device can brush and flush the inner wall of the tower body 100 simultaneously, thoroughly removing impurities adhering to the inner wall of the tower body 100 and preventing any impact on the desulfurization efficiency of the natural gas.
[0025] An air inlet 140 is provided on the lower side of the left side wall of the tower body 100, a slag discharge port 150 is provided at the bottom of the tower body 100, and an air outlet 160 is provided at the top of the tower body 100. A spray pipe 170 is fixedly connected to the upper side of the right side wall of the inner cavity of the tower body 100, and an atomizing nozzle 171 is fixedly connected to the bottom of the spray pipe 170. A liquid inlet pipe 180 is fixedly connected to the upper side of the left side wall of the tower body 100, and the right end of the liquid inlet pipe 180 penetrates the tower body 100 and extends to the top of the tower body 100. The inner cavity of the tower body 100 is connected to the tower body 100. The right end of the inlet pipe 180 is fixedly connected to the left end of the spray pipe 170. The middle of the rear side wall of the inner cavity of the tower body 100 is rotatably connected to the mounting shaft 190. The outer side wall of the mounting shaft 190 is fixedly connected to the dispersing blade 191. The outer side wall of the dispersing blade 191 is provided with a through hole 192. The end of the power output shaft of the motor 300 is fixedly connected to the connecting shaft 310. The end of the connecting shaft 310 passes through the tower body 100 and extends to the tower body 100. The inner cavity is connected to a second bevel gear 320, which is fixedly connected to the end of the connecting shaft 310. The second bevel gear 320 meshes with the first bevel gear 220 and rotates. When the sulfur-containing natural gas enters the tower body 100, it has a high flow velocity, which allows the airflow of sulfur-containing natural gas to push the dispersing blade 191, which in turn causes the dispersing blade 191 to rotate along the mounting shaft 190. This causes the dispersing blade 191 to disperse the sulfur-containing natural gas. At the same time, the dispersing blade 191 cooperates with the through hole 192 to evenly disperse the sulfur-containing natural gas into the interior of the tower body 100. Then, the desulfurization liquid is transported to the spray pipe 170 through the liquid inlet pipe 180, so that the atomizing nozzle 171 sprays the desulfurization liquid in a mist. Finally, the sulfur-containing natural gas is evenly dispersed and the desulfurization liquid is atomized, which ensures that the sulfur-containing natural gas and the desulfurization liquid are in full contact, thereby improving the desulfurization effect of the sulfur-containing natural gas and improving the use effect of the device.
[0026] In practical use, sulfur-containing natural gas is introduced into the tower body 100 through the air inlet 140. This sulfur-containing natural gas pushes the dispersing blades 191, causing them to rotate along the mounting shaft 190. This disperses the sulfur-containing natural gas. Simultaneously, the dispersing blades 191, in conjunction with the through-holes 192, ensure the sulfur-containing natural gas is evenly distributed inside the tower body 100. Then, the desulfurization liquid is transported to the spray pipe 170 through the liquid inlet pipe 180, causing the atomizing nozzles 171 to spray the desulfurization liquid in a mist, ensuring full contact between the sulfur-containing natural gas and the desulfurization liquid. The desulfurized natural gas is then discharged through the air outlet 160, while the waste liquid generated from desulfurization is discharged through the slag discharge port 150. When cleaning the interior of the tower body 100 is required, [further steps are needed]. Water is added to the water tank 120 via the water pipe 121, and then the water in the water tank 120 is transported to the spray frame 110 via the water pump 130. This causes the high-pressure nozzle 111 to spray the water onto the inner wall of the tower body 100, thereby rinsing the inner wall of the tower body 100. The motor 300 drives the connecting shaft 310 to rotate, which in turn drives the second bevel gear 320 to rotate. The second bevel gear 320 then drives the first bevel gear 220 to rotate, which in turn causes the rotating shaft 210 to rotate. The rotating shaft 210 then drives the mounting frame 230 to rotate, causing the scraper 240 to clean the inner wall of the tower body 100. This process of brushing and rinsing the inner wall of the tower body 100 is achieved simultaneously. Finally, the wastewater and impurities generated during the cleaning process are discharged through the slag discharge port 150.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
