Description

A gas desulfurization treatment device after fatty acid production Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically to a desulfurization treatment device for gases produced from fatty acids. Background Technology

[0002] Fatty acids, as core raw materials in the oleochemical, food, and pharmaceutical industries, inevitably generate industrial waste gases containing sulfur oxides and nitrogen oxides during their production, which involve complex chemical reactions. Direct emission of these gases not only causes serious environmental problems such as acid rain and photochemical smog but also harms human health, production equipment, and surrounding ecosystems. With increasing global efforts to control industrial waste gas pollution, countries have enacted legislation to set emission limits for sulfur oxides and nitrogen oxides, creating a rigid constraint that compels companies to upgrade their waste gas treatment technologies.

[0003] Existing devices primarily employ catalytic reduction technology for denitrification of waste gas, while simultaneously using absorbent liquid adsorption technology for desulfurization. These existing technologies are largely similar to a sintering flue gas desulfurization and denitrification device and method, as disclosed in CN108939901B, which separately treats the flue gas requiring denitrification and the flue gas requiring desulfurization. During the denitrification treatment of the flue gas requiring denitrification, heat exchange is performed between the flue gas and the sintered ore to heat and raise the temperature of the flue gas. This invention fully utilizes the waste heat of the sintered ore, using the denitrification flue gas from the sintering flue gas as the heat exchange gas for cooling the sintered ore and raising the temperature of the denitrification flue gas. This not only saves a significant amount of coal gas resources but also allows the use of the traditional SCR technology, which has high denitrification efficiency. Separating the denitrification and desulfurization flue gas further reduces the amount of flue gas requiring desulfurization and denitrification, thereby lowering the load on desulfurization and denitrification processes, offering advantages in energy saving and environmental protection. However, there are still areas for optimization in this device.

[0004] Existing equipment mainly uses two sets of equipment—a desulfurization tower and a denitrification reactor—to treat waste gas. This results in high initial investment and operating costs for some waste gas treatment systems, leading some companies to choose illegal emissions to reduce costs. Secondly, some devices mainly fix the desulfurization and denitrification components in the waste gas duct, making it difficult to use a ring structure to drive multiple sets of desulfurization and denitrification components to treat the waste gas in rotation. This leads to a heavy load on the desulfurization and denitrification components, making it difficult to efficiently treat waste gas with high sulfur and nitrogen content. Finally, some devices require two sets of power units to drive the desulfurization and denitrification components, making it difficult to use a single power unit to simultaneously transport ammonia and absorbent liquid in the treatment tank. This results in a complex power system for some waste gas treatment devices, reducing the efficiency and practicality of the equipment. Therefore, to solve the above problems, a gas desulfurization treatment device after fatty acid production is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a gas desulfurization treatment device after fatty acid production, addressing the problems mentioned in the background section. Existing devices primarily employ two sets of equipment—a desulfurization tower and a denitrification reactor—to treat waste gas, resulting in high initial investment and operating costs for some waste gas treatment systems.

Secondly, some devices mainly fix the desulfurization and denitrification components within the waste gas flow channel, making it difficult to use a ring structure to drive multiple sets of desulfurization and denitrification components for rotating waste gas treatment. This results in a heavy load on the desulfurization and denitrification components, hindering efficient treatment of waste gas with high sulfur and nitrogen content. Finally, some devices require two sets of power units to drive the desulfurization and denitrification components, making it difficult to use a single power unit to simultaneously transport ammonia and absorbent liquid within the treatment tank, thus leading to a complex power system in some waste gas treatment devices.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please refer to Figures 1-8 for one embodiment of the present invention:

[0032] A desulfurization treatment device for fatty acid production includes a base 101. A bracket 102 is fixedly mounted on the front and rear sides of the top of the base 101. A controller 103 is fixedly connected to the front center of the bracket 102. A treatment box 104 is fixedly mounted inside the bracket 102. A desulfurization and denitrification mechanism 2 is installed inside the treatment box 104. A transmission box 105 is fixedly connected to the right side of the treatment box 104. A rotating mechanism 3 is installed inside the transmission box 105. A recovery box 106 is fixedly connected to the bottom of the treatment box 104. The bottom of the recovery box 106 is fixedly mounted on the top right side of the base 101. A pump body 107 is fixedly mounted on the lower left side of the treatment box 104. A feeding mechanism 4 is installed inside the pump body 107. An ammonia storage tank 108 is fixedly connected to the top left side of the base 101. A mixing cylinder 109 is fixedly inserted into the left side wall of the treatment box 104. The left end of the mixing cylinder 109 can be connected to a waste gas discharge pipe. An exhaust seat 110 is fixedly mounted in the middle of the top of the treatment box 104.

[0033] The desulfurization and denitrification mechanism 2 includes a rotating disk 201. The right side of the rotating disk 201 is rotatably connected to the right side of the inner wall of the treatment tank 104. A first rotating frame 202 is fixedly connected to the inner ring of the left side of the rotating disk 201. An activated carbon catalyst plate 203 is fixedly mounted on the outer wall of the first rotating frame 202. Through this design, the activated carbon catalyst plate 203 can assist in catalyzing the reaction between ammonia and nitrogen oxides, so that nitrogen oxides are converted into nitrogen and discharged.

[0034] The right end of the mixing cylinder 109 passes through a through hole in the left side wall of the first rotating frame 202. An air dispersion hole 204 is provided on the outer wall of the mixing cylinder 109 inside the first rotating frame 202. Spiral guide plates 205 are sequentially fixedly arranged on the right side of the interior of the mixing cylinder 109, with adjacent spiral guide plates 205 having opposite spiral directions. A sealing ring 206 is fixedly arranged on the outer wall of the mixing cylinder 109 on the left side of the first rotating frame 202, with the right side of the sealing ring 206 movably fitting against the inner left side ring of the first rotating frame 202. This design enables the mixing cylinder 109 to uniformly mix waste gas and ammonia and discharge them into the interior of the first rotating frame 202, while the sealing ring 206 effectively prevents waste gas from escaping through the through hole.

[0035] The desulfurization and denitrification mechanism 2 also includes a second rotating frame 207. The right side of the second rotating frame 207 is fixedly connected to the left outer ring of the rotating disk 201. An activated carbon adsorption plate 208 is fixedly connected to the outer wall of the second rotating frame 207. A sealing ring plate 209 is fixedly installed on the left side of the inner wall of the treatment box 104. The right side of the sealing ring plate 209 is movably fitted into the left gap between the first rotating frame 202 and the second rotating frame 207. A spray pipe 409 is provided inside the lower part of the second rotating frame 207. The left end of the spray pipe 409 passes through the sealing ring plate 209 and the treatment box 104 in sequence. Through this design, the spray pipe 409 sprays absorbent liquid onto the inner surface of the activated carbon adsorption plate 208, so that the absorbent liquid in the activated carbon adsorption plate 208 can adsorb sulfur-containing gases in the waste gas. At the same time, the sealing ring plate 209 effectively prevents the waste gas from escaping through the left gap between the first rotating frame 202 and the second rotating frame 207.

[0036] The rotating mechanism 3 includes a first motor 301, which is fixedly mounted at the rear of the transmission box 105. A transmission worm 302 is fixedly connected to the middle of the rear of the first motor 301. The rear end of the transmission worm 302 is movably connected to the rear side of the inner wall of the transmission box 105. A transmission worm wheel 303 is meshed with the lower outer wall of the transmission worm 302. Through this design, the first motor 301 drives the transmission worm 302 to rotate in a limited position, which in turn drives the transmission worm wheel 303 to rotate in a limited position. This gives the rotating mechanism 3 a certain degree of self-locking, effectively preventing the rotating disk 201 from reversing.

[0037] A rotating shaft 304 is fixedly connected to the inner wall of the transmission worm gear 303. The right end of the rotating shaft 304 is movably connected to the right side of the inner wall of the transmission box 105. The left end of the rotating shaft 304 passes through the right side wall of the treatment box 104 and is fixedly connected to the main gear 305. An internal gear 306 is meshed with the lower outer wall of the main gear 305. The left side of the internal gear 306 is fixedly connected to the right side of the rotating disk 201. Through this design, the transmission worm gear 303 drives the rotating shaft 304 and the main gear 305 to rotate in a limited position. The main gear 305 meshes and drives the internal gear 306 and the rotating disk 201 to rotate in a limited position. This allows the rotating disk 201 to drive the activated carbon catalyst plate 203 and the activated carbon adsorption plate 208 to rotate synchronously through the first rotating frame 202 and the second rotating frame 207. This allows the activated carbon catalyst plate 203 and the activated carbon adsorption plate 208 to alternately treat sulfides and nitrogen oxides in the waste gas channel.

[0038] A first ball bearing 307 is fixedly connected to the left outer ring of the first rotating frame 202. The left outer sleeve of the first ball bearing 307 is fixedly mounted on the left side of the inner wall of the processing box 104. A second ball bearing 308 is fixedly connected to the left outer ring of the second rotating frame 207. The left outer sleeve of the second ball bearing 308 is fixedly mounted on the left side of the inner wall of the processing box 104. Through this design, stable and limited rotation of the first rotating frame 202 and the second rotating frame 207 inside the processing box 104 is achieved.

[0039] The feeding mechanism 4 includes a second motor 401. The right side of the second motor 401 is fixedly connected to the left side of the pump body 107. A drive shaft 402 is fixedly connected to the middle of the right side of the second motor 401. The right end of the drive shaft 402 is movably connected to the right side of the inner wall of the pump body 107. A wheel frame 403 is fixedly connected to the outer wall of the drive shaft 402 inside the pump body 107 on the left side. A rolling roller 404 is movably connected to the inner outer ring of the wheel frame 403. Through this design, the second motor 401 drives the drive shaft 402 to rotate in a limited position, so that the drive shaft 402 drives the wheel frame 403 and the rolling roller 404 to rotate synchronously.

[0040] A gas delivery pipe 405 is fixedly connected to the top of the ammonia storage tank 108. The outer wall of the gas delivery pipe 405 passes through the gap between the pump body 107 and the rolling roller 404 and is fixedly connected to a gas diffuser 406. The top of the gas diffuser 406 is fixedly installed inside the mixing cylinder 109 on the left side. Through this design, the rolling roller 404, in conjunction with the pump body 107, can roll and compress the gas delivery pipe 405, so that the gas delivery pipe 405 can stably deliver ammonia gas into the mixing cylinder 109.

[0041] A screw conveyor blade 407 is fixedly mounted on the outer wall of the drive shaft 402, inside the right side of the pump body 107. A liquid extraction pipe 408 is movably connected to the bottom center of the pump body 107. The other end of the liquid extraction pipe 408 passes through the top of the recovery tank 106 and is located inside the lower part of the recovery tank 106. The top right side of the pump body 107 is fixedly connected to the left end of the spray pipe 409. Through this design, the drive shaft 402 can drive the screw conveyor blade 407 to rotate in a limited position, so that the screw conveyor blade 407 can cooperate with the pump body 107 to stably transport the absorbent liquid inside the recovery tank 106, and so that the absorbent liquid is sprayed onto the inner surface of the activated carbon adsorption plate 208 through the spray pipe 409.

[0042] Working principle: When desulfurization and denitrification of waste gas are required, the waste gas and ammonia are first mixed through the mixing cylinder 109 and discharged into the interior of the first rotating frame 202. The activated carbon catalyst plate 203 on the first rotating frame 202 can catalyze the reaction between ammonia and nitrogen oxides, so that the nitrogen oxides are converted into nitrogen and discharged. Then, the denitrified waste gas enters the interior of the second rotating frame 207, so that the absorbent liquid in the activated carbon adsorption plate 208 adsorbs the sulfur-containing gas in the waste gas, thus realizing the desulfurization operation of the waste gas.

[0043] When the activated carbon plates need to be rotated, the first motor 301 is started by the controller 103. The first motor 301 drives the transmission worm gear 302 to rotate in a limited position. The transmission worm gear 302 meshes with and drives the transmission worm wheel 303 to rotate. The transmission worm wheel 303 drives the rotating shaft 304 to rotate in a limited position. The rotating shaft 304 drives the main gear 305 to rotate synchronously. The main gear 305 meshes with and drives the internal gear 306 to rotate. The internal gear 306 drives the rotating disk 201 to rotate in a limited position. The rotating disk 201 drives the activated carbon catalyst plate 203 and the activated carbon adsorption plate 208 to rotate synchronously through the first rotating frame 202 and the second rotating frame 207, thus realizing the rotation operation of the activated carbon plates.

[0044] When simultaneous feeding of ammonia and absorbent is required, the second motor 401 is first started by the controller 103. The second motor 401 drives the drive shaft 402 to rotate in a limited position. The drive shaft 402 drives the wheel frame 403 and the rolling roller 404 to rotate synchronously. The rolling roller 404, in conjunction with the pump body 107, rolls and squeezes the gas delivery pipe 405, so that the gas delivery pipe 405 stably delivers the ammonia inside the ammonia storage tank 108 to the mixing cylinder 109. At the same time, the drive shaft 402 drives the auger blade 407 to rotate in a limited position, so that the auger blade 407 can work with the pump body 107 to stably draw the absorbent inside the recovery tank 106, so that the absorbent is sprayed onto the inner surface of the activated carbon adsorption plate 208 through the spray pipe 409, thus realizing the simultaneous feeding operation of ammonia and absorbent. The operation ends here.
