Description

Technical Field

[0001] The utility model relates to the technical field of rotary degassing towers, and particularly relates to a rotary degassing tower for biogas purification. Background Technique

[0002] A rotary degassing tower is a device used to remove gases from materials. Its working principle mainly relies on the packing to contact and transfer the gases in the materials with the liquid, so that the gases are stripped from the liquid phase and collected at the bottom of the device to achieve the purpose of gas removal. According to the different packings, the rotary degassing tower can be divided into two types: plate tower and packed tower.

[0003] For example, the utility model with the application number 201620250524.0 discloses a rotary degassing tower for biogas purification. The rotary degassing tower is placed horizontally along the axis of the rotary packing, one end of which is connected to a driving component. A water pipe is inserted horizontally in the rotary packing, one end of the water pipe protrudes out of the degassing tower body, and a plurality of water outlet holes are arranged on its side wall. The driving component is installed on the outer surface of the degassing tower body. Among them, an air outlet is arranged at the top of the degassing tower body, and a water outlet is arranged at the bottom. The purpose of the utility model is to provide a rotary degassing tower for biogas purification, which can remove excessive CH4 in water (absorbent) and avoid unnecessary energy waste. However, for the rotary degassing tower similar to the one in the above document, due to structural factors, there will be certain structural voids inside the degassing tower body for the rotary packing, resulting in a certain amount of gas that cannot be effectively treated by the packing, thus affecting the purification effect.

The structures of the first packing assembly 3, the second packing assembly 4, the third packing assembly 5, and the fourth packing assembly 6 are the same. The first packing assembly 3, the second packing assembly 4, the third packing assembly 5, and the fourth packing assembly 6 are installed in a staggered manner in a "rice" - shaped structure layer by layer. Stacking and staggering the first packing assembly 3, the second packing assembly 4, the third packing assembly 5, and the fourth packing assembly 6 in a "rice" - shaped structure enables the use of the structure operation of each packing assembly to fully filter the gas entering the interior of the degassing tower assembly 2 to the greatest extent, removing impurities in the gas to ensure the purity of biogas refining.

[0025] As Figures 1 to 5As shown in the figure, the base assembly 1 includes a platform 101, a docking groove 102, support piles 103, a grounding frame 104 and rivets 105. A docking groove 102 is formed in the middle of the top surface of the platform 101, and support piles 103 are installed on the four side edges of the platform 101. The base assembly 1 further includes a grounding frame 104 and rivets 105. A grounding frame 104 is installed at the bottom of the side of the support pile 103 away from the platform 101, and rivets 105 vertically penetrate through the four corners of the grounding frame 104. The support pile 103 is fixedly connected to the platform 101, and the support pile 103 is welded to the grounding frame 104. Moreover, the grounding frame 104 is threadedly connected to the rivet 105. The degassing tower assembly 2 includes a tower top cylinder 201, an air outlet flange 202, a first tower body 203, a second tower body 204, a third tower body 205, a fourth tower body 206 and an air inlet flange 207. An air outlet flange 202 is provided at the top of the tower top cylinder 201, and the bottom of the tower top cylinder 201 is connected to the first tower body 203. Moreover, the bottom of the first tower body 203 is successively connected to the second tower body 204, the third tower body 205 and the fourth tower body 206 from top to bottom. And an air inlet flange 207 is horizontally installed on one side of the fourth tower body 206. The tower top cylinder 201 and the air outlet flange 202 are integrally structured, and the tower top cylinder 201, the first tower body 203, the second tower body 204, the third tower body 205 and the fourth tower body 206 are all connected and fixed to each other by flange structures. Moreover, the surface structure of the bottom of the fourth tower body 206 matches the inner surface structure of the docking groove 102, and the air inlet flange 207 is welded to the fourth tower body 206.

By embedding the bottom of the fourth tower body 206 into the docking groove 102 on the top surface of the platform 101 and cooperating with the connection and fixation of bolts, the entire degassing tower assembly 2 and the base assembly 1 can be stably connected. Additionally, by means of the rivets 105 at the bottom of the support piles 103 around the platform 101 where the grounding frame 104 is installed, and driving them vertically into the ground, the entire equipment can be fixed to the ground.

[0026] In summary, as Figures 1 to 5As shown, when the rotary degassing tower for biogas purification is in use, first place the base assembly 1 in the entire device at the designated installation position.

[0027] After that, connect the intake flange 207 on one side of the fourth tower body 206 to the upstream gas transmission equipment through a pipeline, and then use the outlet flange 202 at the top of the tower top cylinder 201 to communicate with the downstream biogas treatment equipment through a pipeline. When the gas to be purified and filtered is transported into the interior of the entire degassing tower assembly 2, at this time, the first packing assembly 3, the second packing assembly 4, the third packing assembly 5, and the fourth packing assembly 6 located inside the first tower body 203, the second tower body 204, the third tower body 205, and the fourth tower body 206 will operate simultaneously;

[0028] The operation of the servo motor 304 on one side of the fixing frame 305 in cooperation with the gearbox 303 will drive the packing mesh cylinder 301 to rotate axially in the horizontal direction. Using the first packing assembly 3, the second packing assembly 4, the third packing assembly 5, and the fourth packing assembly 6 stacked and staggered in a "meter" - shaped structure, the gas entering the interior of the degassing tower assembly 2 will be further processed as thoroughly as possible by twisting, so as to ensure the purity of biogas purification. After that, the biogas will be transported to the downstream equipment from the outlet flange 202 for further processing of the purified biogas.
