Description

Technical Field

[0001] This invention relates to the field of flue gas treatment technology, and more specifically to a device for enhanced cooling treatment of acidic high-temperature gases. Background Technology

[0002] Acidic high-temperature gases are typical exhaust gases produced during the production processes of industries such as metallurgy, chemical industry, power generation, and waste incineration. They not only contain acidic and corrosive components such as hydrogen chloride, sulfur dioxide, and nitrogen oxides, but also carry high temperatures and dust and fine solid particles. Direct emission of these gases can cause air pollution and corrosion of downstream equipment.

[0003] In existing technologies, spray-type devices for treating acidic high-temperature gases typically include a sealed tank, a single-channel inlet pipe, a top outlet pipe, a packing layer inside the tank, and a spray system and waste liquid recovery tank connected to the tank. Some devices incorporate a single-layer filter plate in the waste liquid recovery tank to filter the alkaline waste liquid after spraying. The filtered waste liquid is then recycled back to the spray system via a circulating pump. Gas enters the tank through the single-channel inlet pipe, passes upwards through the packing layer, and contacts the spray liquid to achieve cooling and deacidification. The treated gas is then discharged through the top outlet pipe. However, existing technologies still have the following problems: The gas is introduced through a single direct inlet, which can easily lead to local accumulation within the tank, resulting in insufficient contact with the sprayed liquid. Furthermore, a large amount of high-temperature gas will continuously flow onto the same packing layer, causing a continuous increase in temperature to the packing layer and the alkaline solution sprayed onto it, thus reducing cooling and deacidification efficiency.

[0004] Based on this, the present invention designs an enhanced cooling treatment device containing acidic high-temperature gas to solve the above problems. Summary of the Invention

[0007] Compared with the prior art, the beneficial effects of this invention are as follows: 1. The acid-containing high-temperature gas enters the diversion component through the inlet pipe and flows towards the location of the sealed tank. Subsequently, the diversion component controls the acid-containing high-temperature gas to flow into different partition components, thereby enabling the acid-containing high-temperature gas to be evenly distributed in the sealed tank. This allows the acid-containing high-temperature gas to undergo sufficient deacidification and cooling treatment, thereby improving the treatment efficiency of the acid-containing high-temperature gas. Furthermore, when the diversion component controls the acid-containing high-temperature gas to flow into different partition components, the circulating deacidification mechanism also sprays alkaline solution into the corresponding partition component, causing the acid-containing high-temperature gas to undergo a neutralization reaction with the alkaline solution, thereby completing the deacidification and cooling treatment. In addition, the partition components further disperse the acid-containing high-temperature gas inside, allowing the acid-containing high-temperature gas to fully contact the alkaline solution, improving the quality of deacidification and cooling, and adsorbing the tiny particles in the acid-containing high-temperature gas. 2. After deacidification and cooling, the purified gas continues to move upwards along the separator to the droplet separator. The droplet separator then separates the droplets entrained in the purified gas from the gas. Finally, the gas, after deacidification, cooling, and droplet separation, is discharged through the discharge pipe for the next processing step. Meanwhile, the alkaline solution sprayed by the circulating deacidification mechanism neutralizes the acid-containing high-temperature gas and flows downwards along the separator into the collection assembly. During this flow, the first and second filter components alternately filter the particulate matter in the alkaline solution. Furthermore, when one of the first and second filter components is filtering, the other performs self-cleaning. This allows the device to continuously and efficiently recover the alkaline solution after neutralization, enabling the alkaline solution to be recycled and reducing the probability of damage to the device during alkaline solution recovery due to particulate matter accumulation, thus extending the device's service life. 3. The circulating deacidification mechanism will extract the alkaline solution after particulate filtration from the base, neutralize the new alkaline solution with the alkaline solution after particulate filtration, and then spray it out from the separation component, thereby realizing the automatic and continuous deacidification and cooling treatment of acid-containing high-temperature gas.

A partition is fixedly installed in the middle of the base 1, dividing the base 1 into two areas, left and right, from the inside. In this invention, acid-containing high-temperature gas enters the diversion assembly through the inlet pipe 31 and flows towards the location of the sealed tank 2. Subsequently, the diversion assembly controls the acid-containing high-temperature gas to flow into different partition components, so that the acid-containing high-temperature gas can be evenly distributed in the sealed tank 2, thereby enabling the acid-containing high-temperature gas to undergo sufficient deacidification and cooling treatment, thereby improving the treatment efficiency of the acid-containing high-temperature gas. Furthermore, when the diversion component controls the flow of acid-containing high-temperature gas to different separation components, the circulating deacidification mechanism 5 also sprays alkaline solution into the corresponding separation component, so that the acid-containing high-temperature gas and the alkaline solution undergo a neutralization reaction, thereby completing the deacidification and cooling process; and the separation component will further disperse the acid-containing high-temperature gas inside, so that the acid-containing high-temperature gas and the alkaline solution can fully contact each other, improve the quality of deacidification and cooling, and adsorb the tiny particles in the acid-containing high-temperature gas. After the deacidification and cooling are completed, the purified gas will continue to move upward along the separator to the location of the droplet separator 22. Then the droplet separator 22 will separate the droplets entrained in the purified gas from the gas. Finally, the gas after deacidification, cooling and droplet separation will be discharged out through the discharge pipe 21 for the next processing step. After the alkaline solution sprayed by the circulating deacidification unit 5 completes the neutralization reaction with the acid-containing high-temperature gas, it will flow down along the separator to the liquid collection unit. During the flow, the first filter unit and the second filter unit will alternately filter the particulate matter in the alkaline solution. Furthermore, when one of the first and second filter components is performing filtration, the other will perform self-cleaning, enabling the device to continuously and efficiently recover the alkaline solution after the neutralization reaction, allowing the alkaline solution to be recycled, and reducing the probability of damage to the device during alkaline solution recovery due to particulate matter accumulation, thus extending the service life of the device. Subsequently, the circulating deacidification mechanism 5 will extract the alkaline solution after particulate filtration from the base 1, neutralize the new alkaline solution with the alkaline solution after particulate filtration, and then spray it out from the separation component, thereby realizing the automatic and continuous deacidification and cooling treatment of acid-containing high-temperature gas.

[0014] Example 2: In some embodiments, such as Figures 1-7 As shown, in a preferred embodiment of the present invention, the diversion assembly includes a rotary joint 32, a control shaft 33, a control motor 34, and a V-shaped guide tube 35; the control shaft 33 is rotatably mounted on the inner bottom of the sealed tank 2; the rotary joint 32 is sleeved on the outside of the control shaft 33; and the stator of the rotary joint 32 is fixedly connected to the inner bottom of the sealed tank 2; the air inlet pipe 31 is connected to the stator of the rotary joint 32. The control motor 34 is fixedly installed on the inner top left side of the base 1; the output end of the control motor 34 is fixedly connected to the control shaft 33; V-shaped guide tube 35 is fixedly installed on the upper end of control shaft 33 and rotatably connected to the middle of diverter tube 36; The rotor of the rotary joint 32 is connected to the interior of the V-shaped guide tube 35 through an air pipe; The separation assembly includes a V-shaped partition plate 39, a grid plate 310, and a filter packing 311; the V-shaped partition plate 39 is fixedly installed on the inner wall of the sealed tank 2; the diversion cylinder 36 is fixedly connected to multiple V-shaped partition plates 39. A clearance groove 38 is provided on the lower side of the V-shaped partition plate 39 to facilitate gas flow; The grid plate 310 is symmetrically fixedly installed on the upper and lower sides of the V-shaped partition plate 39; the filter media 311 is fixedly installed on the upper end of the grid plate 310. V-shaped partition plate 39 is connected to liquid collection assembly and circulating deacidification mechanism 5; In this invention, acid-containing high-temperature gas enters the rotary joint 32 through the inlet pipe 31 and flows along the rotary joint 32 into the V-shaped guide tube 35 and the diverter tube 36. Then, it moves along the outlet hole 37 on the diverter tube 36 and the clearance groove 38 on the V-shaped partition plate 39 into the V-shaped partition plate 39, and moves upward along the V-shaped partition plate 39. Furthermore, the control motor 34 will also drive the control shaft 33 to rotate, causing the control shaft 33 to drive the V-shaped guide tube 35 to rotate along the inner wall of the diversion tube 36. This allows the acid-containing high-temperature gas in the V-shaped guide tube 35 to flow through the vent holes 37 on the diversion tube 36 to different V-shaped partition plates 39, thereby ensuring that the acid-containing high-temperature gas is evenly distributed in the sealed tank 2. This allows the acid-containing high-temperature gas to undergo sufficient deacidification and cooling treatment, thereby improving the processing efficiency of the acid-containing high-temperature gas. Furthermore, when the control motor 34 directs the acid-containing high-temperature gas to different V-shaped partition plates 39, the circulating deacidification mechanism 5 also sprays alkaline solution into the corresponding V-shaped partition plate 39, causing the acid-containing high-temperature gas to undergo a neutralization reaction with the alkaline solution, thereby completing the deacidification and cooling process; and the filter packing 311 further disperses the acid-containing high-temperature gas, allowing the acid-containing high-temperature gas to fully contact the alkaline solution, improving the quality of deacidification and cooling, and adsorbing the tiny particles in the acid-containing high-temperature gas; After the deacidification and cooling are completed, the purified gas will continue to move upward along the V-shaped partition plate 39 to the location of the droplet separator 22. Then, the droplet separator 22 will separate the droplets entrained in the purified gas from the gas. Finally, the gas after deacidification, cooling and droplet separation will be discharged outward through the discharge pipe 21 for the next processing step.

[0015] The circulating deacidification mechanism 5 includes a circulating pump 51, a liquid guide pipe 52, a liquid inlet main pipe 53, a liquid inlet ring pipe 54, a diversion pipe 55, an electric valve 56, a feeding assembly, a feeding pipe 59, and a liquid outlet main pipe 510; the circulating pump 51 is located on the right side of the base 1. The left end of the liquid guide tube 52 is fixedly connected to the right end of the base 1 and communicates with the interior of the base 1; the right end of the liquid guide tube 52 is fixedly connected to the inlet end of the circulating pump 51. The lower end of the liquid inlet pipe 53 is fixedly connected to the liquid outlet end of the circulating pump 51; One end of each of the two inlet ring pipes 54 is fixedly installed at the left end of the inlet main pipe 53 and connected to the inlet main pipe 53; The liquid outlet pipe 510 is fixedly installed on the upper right side of the base 1 and communicates with the interior of the base 1; the other end of the liquid inlet ring pipe 54 is fixedly connected to the liquid outlet pipe 510 and communicates with the interior of the liquid outlet pipe 510. Multiple diversion pipes 55 are fixedly installed in a circumferential array at equal intervals on the inner side of the inlet ring pipe 54 and are connected to the sealed tank 2 and the V-shaped partition plate 39; Multiple spray nozzles 57 are provided on the diversion pipe 55; an electric valve 56 is fixedly installed at the connection between the diversion pipe 55 and the liquid inlet ring pipe 54. The feeding assembly is located to the right of the circulating pump 51; and the inlet pipe 53 is connected to the feeding assembly; The feeding assembly includes a storage tank 58 and a feeding pipe 59; the storage tank 58 is located to the right of the circulating pump 51; the right end of the feeding pipe 59 is fixedly connected to the discharge end of the storage tank 58; the left end of the feeding pipe 59 is fixedly connected to the main inlet pipe 53; an electric valve 56 is also fixedly installed at the connection between the feeding pipe 59 and the main inlet pipe 53. A pump body (not shown in the figure) is fixedly installed at the connection between the feed pipe 59 and the storage tank 58. The storage tank 58 is filled with an alkaline solution; In this invention, acid-containing high-temperature gas enters the rotary joint 32 through the inlet pipe 31 and flows along the rotary joint 32 into the V-shaped guide tube 35 and the diverter tube 36. Then, it moves along the outlet hole 37 on the diverter tube 36 and the clearance groove 38 on the V-shaped partition plate 39 into the V-shaped partition plate 39, and moves upward along the V-shaped partition plate 39. Furthermore, the control motor 34 will also drive the control shaft 33 to rotate, causing the control shaft 33 to drive the V-shaped guide tube 35 to rotate along the inner wall of the diversion tube 36. This allows the acid-containing high-temperature gas in the V-shaped guide tube 35 to flow through the vent holes 37 on the diversion tube 36 to different V-shaped partition plates 39, thereby ensuring that the acid-containing high-temperature gas is evenly distributed in the sealed tank 2. This allows the acid-containing high-temperature gas to undergo sufficient deacidification and cooling treatment, thereby improving the processing efficiency of the acid-containing high-temperature gas. Furthermore, when the control motor 34 directs the acid-containing high-temperature gas to different V-shaped partition plates 39, the circulation pump 51 will extract the alkaline solution after acid-base neutralization from the liquid collection assembly through the liquid guide pipe 52 and pump the alkaline solution into the liquid inlet main pipe 53, so that the alkaline solution flows along the liquid inlet main pipe 53 to the spray nozzle 57. At this time, the alkaline solution in the storage tank 58 will flow along the feed pipe 59 to the liquid inlet main pipe 53 and combine with the alkaline solution after acid-base neutralization, so that the spray solution meets the deacidification conditions again. Subsequently, the spray solution enters the inlet ring pipe 54 along the inlet main pipe 53. When the acid-containing high-temperature gas enters one of the V-shaped partition plates 39, the electric valve 56 corresponding to the V-shaped partition plate 39 will connect the diversion pipe 55 with the inlet ring pipe 54, so that the spray solution is sprayed into the V-shaped partition plate 39 through the spray nozzle 57 and reacts with the acid-containing high-temperature gas to complete the deacidification and cooling process. The spray solution remaining in the inlet ring pipe 54 will also return to the liquid collection assembly through the outlet pipe 510, realizing continuous deacidification and cooling treatment of acid-containing high-temperature gas.

[0016] Example 3: In some embodiments, such as Figures 1-7 As shown, in a preferred embodiment of the present invention, the liquid collection assembly includes a conical ring plate 41, a guide pipe 43, and a diversion plate 44; the conical ring plate 41 is fixedly connected to the lower end of a plurality of V-shaped partition plates 39; liquid outlet grooves 42 are symmetrically opened on the front and rear sides of the inner bottom of the conical ring plate 41. The upper end of the guide pipe 43 is fixedly connected to the liquid outlet tank 42; the lower end of the guide pipe 43 is fixedly connected to the inner top of the base 1. The diversion plate 44 is symmetrically fixedly installed on the front and rear inner walls of the base 1; the upper side of the diversion plate 44 is provided with a downward inclined surface. A sealing groove 45 is provided at one end of the two front and rear diversion plates 44 that are close to each other; and the two front and rear sealing grooves 45 are arranged in an alternating manner. The first filter assembly and the second filter assembly each include a material changing cylinder 46, a filter plate 47, a horizontal guide rod 48, and a cleaning pipe 49; the material changing cylinders 46 of the first filter assembly and the second filter assembly are respectively fixedly installed at the front and rear ends of the base 1. The filter plate 47 is fixedly connected to the output end of the material changing cylinder 46; A horizontal guide rod 48 is also fixedly installed on the filter plate 47; the horizontal guide rod 48 is slidably connected to the base 1; the cleaning pipe 49 is fixedly installed on the inner wall of the base 1; the cleaning pipe 49 has an opening to facilitate liquid outflow; the cleaning pipe 49 is connected to the external pump body through a water pipe. In this invention, the purified gas after deacidification and cooling will continue to move upward along the V-shaped partition plate 39 to the location of the droplet separator 22. Then the droplet separator 22 will separate the droplets entrained in the purified gas from the gas. Finally, the gas after deacidification, cooling and droplet separation will be discharged outward through the discharge pipe 21 for the next processing step. After the alkaline solution sprayed from the spray nozzle 57 completes the neutralization reaction with the acid-containing high-temperature gas, it will flow down along the V-shaped partition plate 39 into the conical ring plate 41, and then through the liquid outlet groove 42 opened at the bottom of the conical ring plate 41 into the guide pipe 43, and through the guide pipe 43 into the base 1, and then flow down along the inclined surface opened at the upper end of the front and rear guide plates 44. During the flow, the filter plates 47 of the first filter assembly and the second filter assembly will alternately adsorb and filter the particulate matter in the alkaline solution. Furthermore, when one of the filter plates 47 in the first and second filter components is performing filtration, the cleaning pipe 49 sprays cleaning fluid onto the other filter plate 47 to flush away the particulate matter in the filter plate 47, thereby achieving self-cleaning of the filter plate 47. After the filter plate 47 completes self-cleaning, the corresponding material replacement cylinder 46 will push the filter plate 47 to move and reset towards the center of the base 1 following the horizontal guide rod 48. This allows the device to perform continuous and efficient recycling of the alkaline solution after the neutralization reaction, enabling the alkaline solution to be recycled and reducing the probability of damage to the device during alkaline solution recycling due to particulate matter accumulation, thus improving the service life of the device. Subsequently, the circulating pump 51 will draw the alkaline solution after particulate matter filtration from the base 1 through the liquid guide pipe 52, and neutralize the new alkaline solution with the alkaline solution after particulate matter filtration, and then spray it out from the V-shaped partition plate 39, thereby realizing the continuous deacidification and cooling treatment of acid-containing high-temperature gas.
