Description

Technical Field

[0001] The invention relates to the technical field of industrial gas processing, and in particular to a bubble reaction tower. Background Art

[0002] The bubble reaction tower is a type of gas-liquid reaction device. It disperses the gas in the reaction through a plate with through holes for mass transfer reaction. Similar to the spray desulfurization tower, the exhaust gas treatment capacity is improved by increasing the gas-liquid contact area. Since the gas is injected into the water, the bubble reaction tower has better exhaust gas treatment capacity than the spray tower by reducing the bubble size and increasing the gas-liquid contact area.

[0003] In the existing bubble reaction tower, the air intake device is located at the bottom of the bubble plate. Since part of the gas participates in the gas-liquid reaction before entering the bubble plate to generate smaller bubbles, precipitation will occur and fall at this position. Common devices only have a solution circulation pipeline. Due to the slow solution circulation speed, the precipitation cannot be removed smoothly, resulting in accumulation, affecting the air intake device and even affecting the bubble generation. In addition, the existing bubble generating device usually faces problems such as high energy consumption and small air volume in order to generate micron-level bubbles. Moreover, due to the surface tension of the liquid, the gas cannot continue to pass through the orifice plate smoothly, affecting the reaction efficiency.

[0004] In the prior art, a Chinese patent document with the announcement number CN106000070B discloses a bubble reaction tower, including a multi-stage reaction zone distributed from bottom to top, and a bubble generator is provided on the air inlet pipeline of each stage of the reaction zone, and the bubble generator is provided with a gas inlet, a liquid inlet, a gas-liquid mixing chamber and a bubble outflow outlet. At the gas-liquid interface, due to the rapid flow of liquid on one side, the gas passing through the air hole is sheared into tiny bubbles at the tip of the air hole corner structure, thereby improving the gas-liquid mass transfer efficiency and reducing energy consumption. However, for a bubble reactor that produces precipitation and impurities, the impurities produced are easily accumulated in the gas-liquid mixing chamber. As the accumulation amount increases and blockage occurs, the overall bubble generation efficiency is affected, and ultimately the overall exhaust gas treatment efficiency is affected. Summary of the invention

[0005] The invention provides a bubble reaction tower to solve the technical problems in the prior art that the air intake structure of the bubble reaction tower is easily blocked and the sediment is difficult to clean.

[0006] To solve the above problems, the present invention provides a bubble reaction tower, including a tower body assembly and a bubble generating mechanism arranged in the tower body assembly, the tower body assembly includes a cylindrical tower body, the bubble generating mechanism includes a bubble generating shell, an air intake mechanism and a bubble plate assembly, and a sediment discharge mechanism is provided at the inner bottom end of the tower body assembly.

[0007] The bubble plate assembly includes a bubble plate and a vibration switch plate. The upper surface of the bubble plate is conical, and the bubble plate is provided with a plurality of exhaust columns that are arranged at intervals and vertically penetrate the bubble plate. The vibration switch plate is conical and is fitted on the upper surface of the bubble plate, and the vibration switch plate is provided with a plurality of air holes.

[0008] A power chamber is provided at the center of the upper end of the bubble plate, a downwardly extending shaft sleeve is provided on the lower surface of the vibration switch plate and the shaft sleeve is rotatably arranged in the power chamber, and a power mechanism for driving the vibration switch plate to reciprocate on the bubble plate is provided in the power chamber.

[0009] By adopting the above technical scheme, a vertically penetrating exhaust column is provided on the bubble plate, and the air holes on the vibration switch plate and the exhaust column can be arranged relative to or staggered, thereby reducing the energy consumption of aeration and enabling the gas to form uniform and small bubbles when passing through the bubble plate, greatly increasing the gas-liquid contact area. The vibration switch plate generates vibration during the reciprocating rotation process, which, on the one hand, facilitates shaking off the precipitated impurities thereon, and on the other hand, disturbs the surrounding liquid, increases the flow of the liquid and the mixing of the bubbles, further enhancing the mixing effect between the reactants and facilitating the reaction.

The floating connection of the telescopic column allows it to have a certain buffer and adjustment space when it is subjected to the force of the toggle gear, and the second spring further enhances this adjustment ability, and cooperates with the elastic reset component to ensure the stability of the vibration frequency and amplitude.

[0021] Furthermore, a discharge pipe is provided at the lower end of the aggregate plate, and the discharge pipe runs through the cylindrical tower body.

The U-shaped tube is an inverted U-shape, which is convenient for assisting in controlling the liquid level height, passively outflowing the liquid, and maintaining the stability of the environment inside the tower and the reaction efficiency.

[0025] The beneficial effects of the present invention are as follows: in the present invention, a vertically penetrating exhaust column is provided on the bubble plate, and the air holes on the vibration switch plate and the exhaust column can be arranged relative to or staggered, thereby reducing the energy consumption of aeration, so that the gas can more smoothly form uniform and fine bubbles when passing through the bubble plate, greatly increasing the gas-liquid contact area, and the vibration switch plate generates vibration during the reciprocating rotation process, which is convenient for shaking off the precipitated impurities thereon on the one hand, and on the other hand, disturbs the surrounding liquid, increases the flow of the liquid and the mixing of the bubbles, further enhances the mixing effect between the reactants, and is conducive to the reaction;

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0042] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0043] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0044] Embodiment of the bubble reaction tower provided by the present invention:

[0045] like Figures 1 to 11 As shown, the bubble reaction tower includes a tower body assembly 1 and a bubble generating mechanism 2 arranged in the tower body assembly 1. The tower body assembly 1 includes a cylindrical tower body 11. The bubble generating mechanism 2 includes a bubble generating shell 21, an air intake mechanism 22 and a bubble plate assembly 23.

[0046] The bubble generating shell 21 is fixedly connected to the inner wall of the cylindrical tower body 11 through a bracket, and a distance is left between the bubble generating shell 21 and the inner wall of the cylindrical tower body 11 .

[0047] The bubble plate assembly 23 includes a bubble plate 231 and a vibration switch plate 233 arranged at the top of the bubble generating shell 21. The upper surface of the bubble plate 231 is conical, and the bubble plate 231 is provided with a plurality of exhaust columns 2311 which are arranged at intervals and vertically penetrate the bubble plate 231. The vibration switch plate 233 is conical and is fitted on the upper surface of the bubble plate 231. The vibration switch plate 233 is provided with a plurality of air holes 2331.

[0048] A power chamber 234 is provided at the center of the upper end of the bubble plate 231, and a downwardly extending shaft sleeve 2332 is provided on the lower surface of the vibration switch plate 233, and the shaft sleeve 2332 is rotatably provided in the power chamber 234. A power mechanism for driving the vibration switch plate 233 to reciprocate on the bubble plate 231 is provided in the power chamber 234. During the reciprocating rotation of the vibration switch plate 233, vibration is generated and the air vent 2331 is arranged vertically opposite to or staggered with the exhaust column 2311.

[0049] Among them, the bubble plate 231 is provided with a vertically penetrating exhaust column 2311, and the air holes 2331 on the vibration switch plate 233 and the exhaust column 2311 can be arranged relative to or staggered, so that the gas can form uniform and small bubbles when passing through the bubble plate 231, reducing the volume of a single bubble and greatly increasing the gas-liquid contact area. The vibration switch plate 233 generates vibration during the reciprocating rotation process, which is convenient for shaking off the precipitated impurities thereon to avoid impurity accumulation and blockage of the bubble plate assembly 23. On the other hand, it will disturb the surrounding liquid, increase the flow of the liquid and the mixing of the bubbles, further enhance the mixing effect between the reactants, and is conducive to the reaction.

[0050] Specifically, a first limit stop 2313 and a second limit stop 2314 are provided at intervals on the bottom surface of the power chamber 234, a baffle 2333 is provided between the first limit stop 2313 and the second limit stop 2314 on the inner wall of the sleeve 2332, a floatingly connected telescopic column 2335 is provided on one side of the baffle 2333, a second spring 5 is provided on the outer sleeve of the telescopic column 2335, and a shift block 2336 is provided at the free end of the telescopic column 2335.

[0051] One end of the telescopic column 2335 slides into the baffle 2333 and cooperates with the second spring 5 to achieve left and right floating movement.

[0052] The power mechanism includes a shifting gear 2321 disposed in the power cavity 234 and driven to rotate by the first motor 232. When the shifting gear 2321 rotates, it intermittently contacts the shifting block 2336. The shifting block 2336 cooperates with the elastic reset component 235 disposed in the power cavity 234 to make the vibration switch plate 233 rotate reciprocatingly.

[0053] Specifically, the top-view cross-section of the shift block 2336 is triangular, which facilitates the cooperation with the shift gear 2321.

[0054] The elastic reset assembly 235 includes a spring guide rod 2351 arranged in the power chamber 234. The spring guide rod 2351 is in an arc shape. One end of the spring guide rod 2351 is provided with a limit plate 2352 fixed on the bottom surface of the power chamber 234. The shaft sleeve 2332 is provided with a guide plate 2334. The spring guide rod 2351 slides through the guide plate 2334. The spring guide rod 2351 is sleeved with a first spring 4 located between the guide plate 2334 and the limit plate 2352.

[0055] In the specific use process, such as Figure 6 , Figure 7 As shown, in the initial state, the first spring 4 is in the original unstressed state, the baffle 2333 is in contact with the second limit block 2314, the toggle gear 2321 rotates counterclockwise, and the toggle block 2336 is driven to drive the vibration switch plate 233 to rotate counterclockwise, while compressing the first spring 4. When the baffle 2333 abuts against the first limit block 2313, the teeth on the toggle gear 2321 and the toggle block 2336 are disengaged from each other. Under the action of the first spring 4, the vibration switch plate 233 rotates clockwise by a certain angle to achieve reset, and this cycle is repeated to achieve the reciprocating rotation motion of the vibration switch plate 233.

[0056] When the teeth on the shifting gear 2321 are disengaged from the shifting block 2336 and are quickly reset by the first spring 4, vibration and shaking effects will be generated.

[0057] In this embodiment, the air intake mechanism 22 includes an air intake pipe 222 and an air intake shower 223. The air intake pipe 222 passes through the bubble generating shell 21. A gate 2221 is provided on the air intake pipe 222. A valve assembly is provided at the gate 2221 for controlling the opening and closing of the gate 2221 according to the liquid level in the bubble generating shell 21.

[0058] Among them, a groove plate 2222 connected to the inside of the air intake pipe 222 is provided at the gate 2221, and the valve assembly includes a floating plate 221 slidably arranged in the groove plate 2222, and a connecting plate 2213 is provided at the lower end of the floating plate 221. The connecting plate 2213 seals and slides through the groove plate 2222 and the bottom end extends out of the groove plate 2222, and the bottom end of the connecting plate 2213 is connected to a floating block 2212.

[0059] When the exhaust column 2311 or the air hole 2331 is blocked, the gas in the bubble generating shell 21 accumulates and a gas cavity is formed under the bubble plate 231, causing the liquid level inside the bubble generating shell 21 to change, that is, the liquid level drops. The float block 2212 follows the change of the liquid level and drives the float plate 221 to move downward, thereby controlling the air intake pipe 222 to be blocked, avoiding continuous introduction of gas when the equipment is blocked. It can also assist in controlling the air intake volume and improve the stability of the overall equipment operation.

[0060] In this embodiment, a sediment discharge mechanism 3 is provided at the inner bottom end of the tower body assembly 1 .

[0061] Among them, the sediment discharge mechanism 3 includes an arc-shaped scraper 31, a collecting plate 32 and a discharging spring piece 33. The collecting plate 32 is placed at the bottom of the cylindrical tower body 11. A baffle plate 321 is fixedly provided at the center of the upper surface of the collecting plate 32. An opening 3221 is provided on the baffle plate 321. The discharging spring piece 33 is arranged at the opening 3221. The collecting plate 32 is provided with a discharge port located in the baffle plate 321.

[0062] A cylindrical sleeve 310 is provided at one end of the arc-shaped scraper 31 , and the cylindrical sleeve 310 is slidably sleeved outside the material-blocking circular plate 321 , and a notch 313 is provided on the cylindrical sleeve 310 .

[0064] A power shaft 312 rotatably supported by the collecting plate 32 is disposed in the cylindrical sleeve 310 . The power shaft 312 penetrates the collecting plate 32 and is driven to rotate by a power member. A partition plate 311 disposed in the cylindrical sleeve 310 is disposed on the power shaft 312 .

[0065] The side surface of the partition plate 311 opposite to the cylindrical sleeve 310 is fixedly connected to the inner wall of the cylindrical sleeve 310 .

[0066] A discharge pipe 34 is provided at the lower end of the collecting plate 32 , and the discharge pipe 34 runs through the cylindrical tower body 11 .

[0067] In the specific use process, such as Fig.11 Some precipitated impurities produced by the reaction of gas and solution will be deposited on the upper surface of the collecting plate 32. During the rotation of the power shaft 312, the arc scraper 31 is driven to scrape and collect the precipitated impurities on the surface of the collecting plate 32. During the rotation of the cylindrical sleeve 310, when the notch 313 is opposite to the opening 3221, the discharge spring 33 pops open, and the collected impurities will enter the retaining circular plate 321 and be gradually discharged from the discharge port through the discharge pipe 34 to avoid the accumulation of precipitated impurities inside.

[0069] The solution circulation outlet pipe 13 is connected to the U-shaped tube 10 at the pipe opening outside the cylindrical tower body 11. The U-shaped tube 10 is an inverted U-shape, which is convenient for assisting in controlling the liquid level, passively outflowing the liquid, and maintaining the stability of the environment inside the tower and the reaction efficiency.

[0070] During the overall use of the bubble reaction tower of the present invention, the gas enters from the air intake pipe 222 and is dispersed into the bubble generating shell 21 for the first time through the air intake shower 223. The rising bubbles will rise through the exhaust column 2311 on the bubble plate 231. When the exhaust column 2311 is opposite to the air hole 2331, the gas is discharged. In addition, the rotation of the vibration switch plate 233 can reduce the volume of a single bubble, greatly increasing the gas-liquid contact area, and the rising bubbles fully react with the solution to improve the treatment effect and efficiency of the exhaust gas.

[0071] The precipitated impurities generated by the reaction of the gas and the solution are automatically discharged through the precipitate discharge mechanism 3, and the operator does not need to frequently stop the machine to clean the precipitate, thereby improving the overall production efficiency.
