[0002] A rotary desulfurization tower mainly consists of a tower body, an inlet, an outlet, a rotary gas distributor, a spray system, desulfurizing agent packing, a mixing device, and related pipes, valves, and monitoring equipment. Biogas typically contains a certain amount of impurities, including solid particles (such as dust, sand, and fermentation residue), liquid droplets (such as water vapor and unseparated fermentation liquid), and some gaseous impurities (such as carbon dioxide and nitrogen). If these impurities enter the desulfurization tower with the biogas, they will adversely affect the desulfurization process and the equipment.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: biogas usually contains a certain amount of impurities, including solid particles (such as dust, sand, fermentation residue, etc.), liquid droplets (such as water vapor, unseparated fermentation liquid, etc.), and some gaseous impurities (such as carbon dioxide, nitrogen, etc.). If these impurities enter the desulfurization tower with the biogas, they will have an adverse effect on the desulfurization process and equipment. Because solid impurities enter the tower, the desulfurization microorganisms are affected, resulting in a reduction in desulfurization capacity. Therefore, a rotary biogas biological desulfurization tower is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where solid impurities entering the tower affect the desulfurization microorganisms, thereby reducing the desulfurization capacity. Therefore, a rotary biogas biological desulfurization tower is proposed.

[0016] The effect achieved by the above-mentioned components is to block the fixing rod, preventing the fixing rod from falling out of the connecting frame due to shaking caused by external factors, thus preventing the fixing rod from being damaged and unable to continue to be used.

[0017] Preferably, the arc surface of the rotating rod is fitted with a torsion spring, and the two ends of the torsion spring are fixedly connected to the support plate and the protective cover, respectively.

[0028] Reference Figure 1As shown, this utility model provides a technical solution: a rotary biogas biological desulfurization tower, including a desulfurization tower body 1. The surface of the desulfurization tower body 1 is provided with an auxiliary device 2, which achieves the effect of filtering solid impurities, avoiding the situation where solid impurities enter the tower and affect the desulfurization microorganisms, thereby reducing the desulfurization capacity and improving the practicality of the device. The surface of the desulfurization tower body 1 is provided with a protective device 3, which achieves the effect of protecting the exhaust port of the desulfurization tower body 1, avoiding the situation where rainwater flows in and dilutes the desulfurizing agent in the tower and causes rust and corrosion of the facilities in the tower, thereby affecting the entire desulfurization system and improving the practicality of the device.

[0029] The specific setup and function of its auxiliary device 2 and protective device 3 will be described in detail below.

[0030] Reference Figure 2As shown in this embodiment: the auxiliary device 2 includes two short rods 201, which are fixedly connected to the surface of the desulfurization tower body 1. One end of each short rod 201 is fixedly connected to a screw plate 204. A push plate 202 is slidably connected to the arc surface of each short rod 201. A limiting rod 205 is slidably inserted into the push plate 202. One end of the limiting rod 205 is fixedly connected to a circular plate 207. A filter screen 211 is slidably connected to the surface of the desulfurization tower body 1. Two limiting grooves 208 are formed on the surface of the filter screen 211. A spring 206 is fitted onto the arc surface of the limiting rod 205. The two ends of the spring 206 are respectively connected to the push plate 204. The moving plate 202 and the circular plate 207 are fixedly connected. When the circular plate 207 is released, the rebound force of the spring 206 drives the circular plate 207, which in turn drives the limiting rod 205 to slide within the pushing plate 202 until the limiting rod 205 is inserted into the limiting groove 208. This achieves a stable connection of the limiting rod 205, preventing shaking caused by external factors from causing the limiting rod 205 to detach from the filter screen 211 and improving the stability of the device. The arc surface of the short rod 201 is rotatably connected to a rotating ring 203, and the surface of the rotating ring 203 is fixedly connected to the pushing plate 202. The surface of the desulfurization tower body 1 is provided with... The recycling trough 209 works by pulling the limiting rod 205 out of the limiting groove 208, then rotating the rotating ring 203 to drive the push plate 202 to rotate on the arc surface of the short rod 201. The push plate 202 drives the limiting rod 205, which in turn drives the circular plate 207 until the limiting rod 205 is perpendicular to the recycling trough 209. Then, the circular plate 207 is pushed, causing the limiting rod 205 to slide within the push plate 202 until the limiting rod 205 is inserted into the recycling trough 209. This achieves the effect of rotating and recycling the limiting rod 205, avoiding the shaking caused during disassembly that would cause the limiting rod 205 to move back and forth within the push plate 202. The sliding motion causes the staff to continuously pull the limit rod 205. The surface of the desulfurization tower body 1 is fixedly connected to the positioning plate 210. The size of the limit rod 205 is adapted to the size of the limit groove 208. Rotating the rotating ring 203 drives the push plate 202 to rotate on the arc surface of the short rod 201. The push plate 202 drives the limit rod 205, and the limit rod 205 drives the circular plate 207 until the limit rod 205 touches the positioning plate 210, achieving the effect of quickly positioning the limit rod 205. This allows the staff to quickly complete the cleaning and installation of the filter screen 211, thereby accelerating the desulfurization speed of biogas.

[0031] Reference Figure 3 , Figure 4 as well as Figure 5As shown, specifically, the protective device 3 includes a connecting block 31, which is fixedly connected to the surface of the desulfurization tower body 1. A connecting rod 32 is fixedly connected inside the connecting block 31, and support plates 33 are fixedly connected to both ends of the connecting rod 32. A rotating rod 34 is fixedly connected to one side of the two support plates 33 that are close to each other. A protective cover 36 is rotatably connected to the arc surface of the rotating rod 34. A fixing groove is opened on the surface of the protective cover 36. A connecting frame 37 is fixedly connected to one side of the support plate 33. A fixing rod 38 is slidably inserted into the connecting frame 37. A baffle 39 is fixedly connected to the arc surface of the fixing rod 38. The size of the fixing rod 38 is adapted to the size of the fixing groove on the surface of the protective cover 36. By pulling the fixing rod 38, it slides in the connecting frame 37, and the fixing rod 38... The baffle 39 moves until it touches the connecting frame 37, thus blocking the fixed rod 38 and preventing it from falling off the connecting frame 37 due to shaking caused by external factors. This would prevent the fixed rod 38 from being damaged and unusable. The arc surface of the rotating rod 34 is fitted with a torsion spring 35, and the two ends of the torsion spring 35 are fixedly connected to the support plate 33 and the protective cover 36, respectively. When the protective cover 36 is released, the torque of the torsion spring 35 drives the protective cover 36 to rotate on the arc surface of the rotating rod 34 until the protective cover 36 fits against the exhaust port of the desulfurization tower, thus achieving the effect of automatically closing the protective cover 36. This reduces the number of operating steps for the staff, increases the work efficiency of the staff, and improves the convenience of the device.

[0032] Working principle: When the filter screen 211 needs cleaning, the limiting rod 205 is pulled out from the limiting groove 208, and then the rotating ring 203 is rotated to drive the pushing plate 202 to rotate on the arc surface of the short rod 201. The pushing plate 202 drives the limiting rod 205, and the limiting rod 205 drives the circular plate 207 until the limiting rod 205 touches the positioning plate 210. Then the circular plate 207 is pushed, and the circular plate 207 drives the limiting rod 205 to slide within the pushing plate 202 until the limiting rod 205 is inserted into the recycling groove 209. After cleaning, when installing, the limiting rod 205 is pulled out from the recycling groove 209, and then the rotating ring 203 is rotated. The push plate 202 rotates on the arc surface of the short rod 201, which in turn drives the limiting rod 205. The limiting rod 205 then drives the circular plate 207 until the limiting rod 205 is perpendicular to the limiting groove 208. The circular plate 207 is then released, and the spring force of the spring 206 drives the circular plate 207. The circular plate 207 then drives the limiting rod 205 to slide within the push plate 202 until the limiting rod 205 is inserted into the limiting groove 208. This achieves the effect of filtering solid impurities, preventing the desulfurization microorganisms from being affected by solid impurities entering the tower, thus avoiding a reduction in desulfurization capacity and improving the practicality of the device.

[0033] When protection is not required, the protective cover 36 is pushed to rotate on the arc surface of the rotating rod 34 until the protective cover 36 is fully opened. When protection is required, the fixed rod 38 is pulled to slide within the connecting frame 37. The fixed rod 38 drives the baffle 39 until the baffle 39 touches the connecting frame 37. The torque of the torsion spring 35 drives the protective cover 36 to rotate on the arc surface of the rotating rod 34 until the protective cover 36 fits against the exhaust port of the desulfurization tower. This achieves the effect of protecting the exhaust port of the desulfurization tower body 1, preventing the desulfurizing agent inside the tower from being diluted and the facilities inside the tower from rusting and corroding due to the inflow of rainwater, thus affecting the entire desulfurization system and improving the practicality of the device.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
