Description

Technical Field

[0001] This invention belongs to the technical field of wastewater treatment equipment, specifically relating to a wet catalytic oxidation reactor with wastewater degassing function. Background Technology

[0002] With the continuous progress and development of production and daily life, water resource problems are becoming increasingly prominent, among which the treatment of industrial and domestic wastewater is particularly important and closely related to the quality of social development. Wet catalytic oxidation technology, as a highly efficient advanced oxidation process, has significant advantages in treating high-concentration, recalcitrant, and toxic industrial wastewater. This technology utilizes a catalyst to activate the oxidant under high temperature and pressure conditions, generating highly oxidizing hydroxyl radicals, thereby completely degrading organic pollutants into carbon dioxide, water, and small-molecule inorganic substances.

[0003] In traditional reactors, heat is typically added from the bottom or sidewalls. Due to the low density of the hydrothermal fluid, it naturally rises, creating strong temperature stratification within the reactor, resulting in a high temperature at the bottom and a low temperature at the top. This non-uniformity leads to uneven wastewater reaction rates, with the reaction rate in the lower-temperature upper zone being significantly slower than that in the higher-temperature lower zone. This lowers the average efficiency of the entire reactor, increases energy consumption, and creates conditions for the formation of byproducts. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a wet catalytic oxidation reactor with wastewater degassing function.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows: a wet catalytic oxidation reactor with wastewater degassing function, including a catalytic reaction shell, an upper fixed seat fixedly connected to the lower end of the catalytic reaction shell, a degassing reaction shell arranged below the upper fixed seat, a lower fixed seat fixedly connected to the upper end of the degassing reaction shell, the lower fixed seat and the upper fixed seat being fixedly installed by multiple fixing bolts, a reaction cover arranged on the top of the catalytic reaction shell, a feed pipe fixedly connected to one side of the upper end of the reaction cover, a sealing strip fixedly connected to the lower surface of the reaction cover, a guide ring fixedly installed inside the lower end of the catalytic reaction shell; an exhaust pipe fixedly connected to one side of the catalytic reaction shell, a pressurization pipe fixedly connected to the other side of the catalytic reaction shell, an integrated drive assembly arranged on one side of the catalytic reaction shell, and a degassing reinforcement assembly fixedly installed on the degassing reaction shell.

[0006] Through the above technical solution, after the wastewater fully reacts with the catalytic particles inside the catalytic bed, it permeates out and falls into the degassing reaction shell through the guiding effect of the guide ring. The sealing strip set on the lower surface of the reaction cover can realize the high-pressure sealing of the reactor, maintain a stable pressure environment inside the reactor, and at the same time, it can also isolate the intrusion of external air to avoid interfering with the catalytic reaction and degassing of the wastewater.

[0007] Furthermore, valves are fixedly connected to both the exhaust pipe and the pressurization pipe, and the exhaust pipe and the pressurization pipe are interconnected with the interior of the catalytic reaction shell. A pressurization device is fixedly installed at the end of the pressurization pipe away from the catalytic reaction shell.

[0008] Through the above technical solution, the pressurization device greatly improves the solubility of ozone in wastewater during the reaction, providing more sufficient oxidant for the reaction. At high temperatures, water easily boils and vaporizes, and pressurization can raise the boiling point of water, ensuring that the wastewater remains liquid in the reactor at all times.

[0009] Furthermore, a support frame is fixedly connected to the lower end of the degassing reaction shell, and multiple sets of fixing ribs are evenly fixedly connected to the lower surface of the support frame. The other end of the fixing ribs is fixedly installed between the support base and the lower surface of the support base. A rubber pad is fixedly connected to the lower end of the degassing reaction shell, and a discharge pipe is fixedly connected to the discharge pipe. A valve is fixedly installed on the discharge pipe.

[0010] With the above technical solution, after the liquid reaction is completed, the valve on the discharge pipe is opened. The reactor usually maintains a high pressure during operation. When the valve is opened, this pressure difference will act as a powerful driving force to instantly push the liquid toward the low-pressure outlet, thereby achieving rapid unloading, shortening the production or processing cycle, and improving equipment utilization.

[0011] Furthermore, the integrated drive assembly includes a top plate mounting bracket fixedly installed on one side of the upper end of the reaction cover. Guide rods are symmetrically slidably connected to the top plate mounting bracket. A mounting base is fixedly connected to the lower end of the guide rods. The mounting base is fixedly connected to the outer wall of the catalytic reaction shell. A drive motor is fixedly installed inside the mounting base. A threaded rod is fixedly connected to the output end of the drive motor. The threaded rod is threadedly connected to the top plate mounting bracket. A weight block is fixedly installed at the end of the top plate mounting bracket away from the reaction cover.

[0012] Through the above technical solution, the drive motor drives the threaded rod to rotate. The threaded rod drives the top plate fixing frame and the reaction cover integrated with the top plate fixing frame to move upward through the threaded connection. The upward movement of the reaction cover in turn drives the catalyst fixing seat, which is magnetically fixed to the connecting column, to move upward. After the connecting column is completely removed from the device, the staff can more easily clean the inside of the device.

[0013] Furthermore, a connecting column is fixedly connected inside the reaction cover, and a connecting crossbar is evenly fixedly connected around the circumference of the connecting column. A mounting bracket is fixedly connected to the end of the connecting crossbar away from the connecting column. An outer ring positive magnetic block is fixedly embedded inside the mounting bracket, and an inner ring positive magnetic block is fixedly embedded on the outer wall of the lower end of the connecting column.

[0014] Furthermore, a catalytic fixing seat is sleeved on the outer side of the lower end of the connecting column, a catalytic bed is fixedly installed between the catalytic fixing seats, the catalytic bed is filled with catalytic particles, an inner ring negative pole magnetic block is fixedly embedded in the inner ring of the catalytic fixing seat, and an outer ring negative pole magnetic block is fixedly embedded in the outer ring of the catalytic fixing seat.

[0015] With the above technical solution, wastewater containing oxidant is sprayed onto the catalyst bed. After the wastewater fully reacts with the catalytic particles inside the catalyst bed, it permeates out. By holding both ends of the catalyst fixing seat, the catalyst bed can be directly separated from the connecting column, and the catalyst bed can be replaced.

[0016] Furthermore, the degassing enhancement component includes two fan-shaped air outlet seats fixedly installed inside the degassing reaction shell. The fan-shaped air outlet seats are inclined hole structures sloping towards the lower end of the degassing reaction shell. Air guide covers are symmetrically fixedly installed on the outer side of the degassing reaction shell, and the air guide covers communicate with the fan-shaped air outlet seats. A hot air cavity is opened inside the air guide cover. A wind guide plate is fixedly connected to one side of the center of the air guide cover, dividing the hot air cavity into two cavities. One end of each of the two air guide covers is fixed... The device is connected to an air supply duct. An air outlet is provided at one end of the air supply duct near the air supply duct. The air supply duct is connected to the hot air cavity through the air outlet. The ends of the two air supply ducts away from the air supply duct are installed between them and the installation fan. The installation fan is fixedly installed on a fixed plate. The fixed plate is fixedly installed between it and the degassing reaction shell. An air intake duct is fixedly installed at the lower end of the installation fan. The air inlet of the installation fan is fixedly connected to one end of the air intake duct. The other ends of the two air supply ducts are connected to the air outlet of the installation fan.

[0017] Through the above technical solution, the installed fan will draw hot air generated inside the heating chamber through the suction duct, and send part of the hot air inside the heating chamber into two air guide hoods through two air supply ducts. Then, the hot air will be blown into the upper part of the wastewater reaction liquid through the corresponding fan-shaped air outlet. The installed fan can quickly compensate for the heat required by the upper liquid reaction by delivering the hot air in the lower hot air chamber to the upper part of the lower liquid. This will quickly deliver the high temperature hot air accumulated in the bottom hot air chamber to the upper part of the lower temperature liquid, thereby eliminating the vertical temperature gradient during the wastewater reaction and making the liquid temperature in the entire degassing reaction shell more stable.

[0018] Furthermore, a heating seat is fixedly connected to the lower end of the degassing reaction shell. The heating seat is made of stainless steel. A heating cavity is provided between the heating seat and the degassing reaction shell. A heating disc tube is fixedly connected to the heating cavity. The end of the suction pipe away from the air inlet of the fan is fixedly extended into the heating cavity.

[0019] By connecting the power supply to the heating disc tube, the wastewater can undergo a heating oxidation reaction. The heating base can conduct heat to the wastewater reaction liquid above, providing a basic heat source for the entire reaction system, maintaining the temperature inside the degassing reaction shell, thereby activating the catalyst activity and accelerating the oxidation and degradation of recalcitrant organic matter.

[0020] The beneficial effects of the present invention are as follows: (1) The present invention, through the design of a matching integrated drive assembly and multiple magnetic pole blocks fixed inside the catalyst fixing seat, allows the threaded rod to drive the top plate fixing frame and the reaction cover integrated with the top plate fixing frame to move upward through the threaded connection. The upward movement of the reaction cover can then drive the catalyst fixing seat, which is magnetically fixed to the connecting column, to move upward. After the connecting column is completely removed from the device, the staff can more easily clean the inside of the device. At the same time, the setting of multiple magnetic blocks makes the replacement of the catalyst bed more convenient, improving the cleaning and maintenance efficiency of the entire device; (2) The present invention, through the design of a matching integrated drive assembly and multiple magnetic pole blocks fixed inside the catalyst fixing seat, allows the threaded rod to drive the top plate fixing frame and the reaction cover integrated with the top plate fixing frame to move upward through the threaded connection. The upward movement of the reaction cover can then drive the catalyst fixing seat, which is magnetically fixed to the connecting column, to move upward through the connecting column. After the connecting column is completely removed from the device, the staff can more easily clean the inside of the device. At the same time, the setting of multiple magnetic pole blocks makes the replacement of the catalyst bed more convenient, improving the cleaning and maintenance efficiency of the entire device; (2) The present invention, through the design of a matching integrated drive assembly and multiple magnetic pole blocks fixed inside the catalyst fixing seat, allows the threaded rod to drive the top plate fixing frame and the reaction cover integrated with the top plate fixing frame to move upward through the threaded connection.

The The degassing enhancement component uses a lower heating disc tube to directly transfer heat to the wastewater at the bottom of the degassing reaction shell via a heating base, providing a basic heat source for the entire reaction system and maintaining the temperature inside the degassing reaction shell. A fan is installed to transport hot air from the lower hot air chamber to the liquid above, which can quickly compensate for the heat required for the reaction of the liquid above. The high-temperature hot air accumulated in the bottom hot air chamber is quickly transported to the upper part of the cooler liquid, thereby eliminating the vertical temperature gradient during the wastewater reaction, making the liquid temperature inside the entire degassing reaction shell more stable, increasing the reaction rate within the device, and improving the degradation efficiency of pollutants.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] like Figures 1-3As shown, this embodiment of a wet catalytic oxidation reactor with wastewater degassing function includes a catalytic reaction shell 1. An upper fixing seat 10 is fixedly connected to the lower end of the catalytic reaction shell 1. A degassing reaction shell 11 is disposed below the upper fixing seat 10. A lower fixing seat 12 is fixedly connected to the upper end of the degassing reaction shell 11. The lower fixing seat 12 and the upper fixing seat 10 are fixedly installed by multiple fixing bolts 13. A reaction cover 2 is disposed above the catalytic reaction shell 1. A feed pipe 20 is fixedly connected to one side of the upper end of the reaction cover 2. A sealing strip is fixedly connected to the lower surface of the reaction cover 2. A guide is fixedly installed inside the lower end of the catalytic reaction shell 1. The catalytic reaction shell 1 is fixedly connected to an exhaust pipe 17 on one side and a pressurization pipe 18 on the other side. An integrated drive assembly 3 is provided on one side of the catalytic reaction shell 1. A degassing reinforcement assembly 5 is fixedly installed on the degassing reaction shell 11. After the wastewater fully reacts with the catalytic particles inside the catalytic bed 40, it permeates out and falls into the degassing reaction shell 11 through the guiding effect of the flow guide ring. The sealing strip provided on the lower surface of the reaction cover 2 can achieve high-pressure sealing of the reactor, maintain a stable pressure environment inside the reactor, and at the same time isolate external air from intrusion to avoid interfering with the catalytic reaction and degassing of the wastewater.

[0034] like Figures 1-2 As shown, valves are fixedly connected to both the exhaust pipe 17 and the pressurization pipe 18. The exhaust pipe 17 and the pressurization pipe 18 are interconnected with the interior of the catalytic reaction shell 1. A pressurization device is fixedly installed at the end of the pressurization pipe 18 away from the catalytic reaction shell 1. During the reaction, the pressurization device greatly increases the solubility of ozone in the wastewater, providing more sufficient oxidant for the reaction. At high temperatures, water easily boils and vaporizes. Pressurization raises the boiling point of water, ensuring that the wastewater remains liquid in the reactor. A support frame 14 is fixedly connected to the lower end of the degassing reaction shell 11. Multiple sets of fixing ribs 15 are evenly fixedly connected to the lower circumference of the support frame 14. The other end of the fixing ribs 15 is fixedly installed between the support base 16 and the lower surface of the support base 16. A rubber pad is fixedly connected to the lower end of the degassing reaction shell 11. A discharge pipe 19 is fixedly installed on the discharge pipe 19. After the liquid reaction is completed, the valve on the discharge pipe 19 is opened. The reactor usually maintains a high pressure during operation. When the valve is opened, this pressure difference acts as a powerful driving force, instantly pushing the liquid towards the low-pressure outlet, achieving rapid unloading, thereby shortening the production or processing cycle and improving equipment utilization.

[0035] like Figures 1-2As shown, the integrated drive assembly 3 includes a top plate mounting bracket 30 fixedly installed on one side of the upper end of the reaction cover 2. A guide rod 31 is symmetrically slidably connected to the top plate mounting bracket 30. A mounting base 33 is fixedly connected to the lower end of the guide rod 31. The mounting base 33 is fixedly connected to the outer wall of the catalytic reaction shell 1. A drive motor 34 is fixedly installed inside the mounting base 33. A threaded rod 32 is fixedly connected to the output end of the drive motor 34. The threaded rod 32 is threadedly connected to the top plate mounting bracket 30. A weight block 35 is fixedly installed at the end of the top plate mounting bracket 30 away from the reaction cover 2. The drive motor 34 drives the threaded rod 32 to rotate. The threaded rod 32 drives the top plate mounting bracket 30 and the reaction cover 2, which is integrated with the top plate mounting bracket 30, to move upward through the threaded connection. The upward movement of the reaction cover 2 drives the catalytic fixing seat 4, which is magnetically fixed to the connecting column 36, to move upward. After the connecting column 36 is completely removed from the device, the staff can more easily clean the inside of the device.

[0036] like Figures 1-5 As shown, a connecting column 36 is fixedly connected inside the reaction cover 2. A connecting crossbar 37 is evenly fixedly connected around the circumference of the connecting column 36. A mounting bracket 38 is fixedly connected to the end of the connecting crossbar 37 away from the connecting column 36. An outer ring positive electrode magnetic block 39 is fixedly embedded inside the mounting bracket 38. An inner ring positive electrode magnetic block 310 is fixedly embedded on the lower outer wall of the connecting column 36. A catalyst fixing seat 4 is sleeved on the lower outer side of the connecting column 36. A catalyst bed 40 is fixedly installed between the catalyst fixing seats 4. The catalyst bed 40 is filled with catalyst particles. An inner ring negative electrode magnetic block 42 is fixedly embedded in the inner ring of the catalyst fixing seat 4. An outer ring negative electrode magnetic block 41 is fixedly embedded in the outer ring of the catalyst fixing seat 4. Wastewater containing oxidant is sprinkled onto the catalyst bed 40. After the wastewater fully reacts with the catalyst particles inside the catalyst bed 40, it seeps out. By holding both ends of the catalyst fixing seat 4, the catalyst bed 40 can be directly separated from the connecting column 36, and the catalyst bed 40 can be replaced.

[0037] like Figures 1-10As shown, the degassing enhancement component 5 includes two fan-shaped air outlet seats 57 fixedly installed inside the degassing reaction housing 11. The fan-shaped air outlet seats 57 have oblique hole structures that slope towards the lower end of the degassing reaction housing 11. Air guide mounting covers 54 are symmetrically fixedly installed on the outer side of the degassing reaction housing 11. The air guide mounting covers 54 and the fan-shaped air outlet seats 57 are interconnected. A hot air cavity 58 is opened inside the air guide mounting covers 54. An air guide plate 5 is fixedly connected to one side of the center of the air guide mounting covers 54. 6. The air guide plate 56 divides the hot air cavity 58 into two cavities. One end of each of the two air guide mounting covers 54 is fixedly connected to an air supply duct 52. An air outlet 55 is provided at the end of the air guide mounting cover 54 near the air supply duct 52. The air supply duct 52 is connected to the hot air cavity 58 through the air outlet 55. The ends of the two air supply ducts 52 away from the air guide mounting cover 54 are installed between them and the mounting fan 51. The mounting fan 51 is fixedly mounted on the fixing plate 50. The fan 51 is fixedly installed with the degassing reaction shell 11. The lower end of the fan 51 is fixedly installed with a suction pipe 53. The air inlet of the fan 51 is fixedly connected to one end of the suction pipe 53. The other ends of the two air supply pipes 52 are connected to the air outlet of the fan 51. The fan 51 draws hot air generated inside the heating chamber 510 through the suction pipe 53 and sends part of the hot air inside the heating chamber 510 into the two air guide mounting covers 54 through the two air supply pipes 52. Then the hot air is blown into the upper part of the wastewater reaction liquid through the corresponding fan-shaped air outlet seat 57. The fan 51 delivers the hot air in the lower hot air chamber 58 to the upper part of the liquid to quickly compensate for the heat required by the upper liquid reaction. The high temperature hot air accumulated in the lower hot air chamber 58 is quickly delivered to the upper part of the lower temperature liquid, thereby eliminating the vertical temperature gradient during the wastewater reaction and making the liquid temperature in the entire degassing reaction shell 11 more stable.

[0038] like Figures 1-9 As shown, a heating base 59 is fixedly connected to the lower end of the degassing reaction shell 11. The heating base 59 is made of stainless steel. A heating chamber 510 is provided between the heating base 59 and the degassing reaction shell 11. A heating disc tube 511 is fixedly connected inside the heating chamber 510. The end of the suction pipe 53 away from the air inlet of the fan 51 is fixedly extended into the heating chamber 510. When the power supply of the heating disc tube 511 is turned on, the wastewater can undergo a heating oxidation reaction. The heating base 59 can conduct heat to the wastewater reaction liquid above, providing a basic heat source for the entire reaction system, maintaining the temperature inside the degassing reaction shell 11, thereby activating the catalyst activity and accelerating the oxidation and degradation of recalcitrant organic matter.

[0039] The working principle of this embodiment is as follows: the staff puts the wastewater containing oxidant into the catalytic reaction shell 1 through the guiding effect of the feed pipe 20. The wastewater is sprinkled on the catalytic bed 40. After the wastewater fully reacts with the catalytic particles inside the catalytic bed 40, it permeates out and falls into the degassing reaction shell 11 through the guiding effect of the guide ring.

[0040] Power is switched on to the heating disc tube 511, enabling the wastewater to undergo a heating and oxidation reaction. Simultaneously, the installation fan 51 is activated. The installation fan 51 draws in the hot air generated inside the heating chamber 510 through the suction pipe 53 and sends some of the hot air inside the heating chamber 510 into the two air guide mounting covers 54 through the two air supply pipes 52. Then, the hot air is blown into the wastewater reaction liquid above through the corresponding fan-shaped air outlet seat 57. At the same time, when the heating disc tube 511 is heating, the heating seat 59 can conduct heat to the wastewater reaction liquid above, thereby activating the catalyst activity and accelerating the oxidation and degradation of refractory organic matter. Furthermore, some of the hot air inside the heating chamber 510 is drawn away to prevent the temperature around the heating disc tube 511 from rising continuously, thus stabilizing the operating temperature of the heating disc tube 511 within the design range.

[0041] When the device needs to be cleaned after a period of use, the drive motor 34 drives the threaded rod 32 to rotate. The threaded rod 32 drives the top plate fixing frame 30 and the reaction cover 2, which is integrated with the top plate fixing frame 30, to move upward through the threaded connection. The upward movement of the reaction cover 2 in turn drives the catalyst fixing seat 4, which is magnetically fixed to the connecting column 36, to move upward. At this time, by holding both ends of the catalyst fixing seat 4, the catalyst bed 40 can be directly separated from the connecting column 36, and the catalyst bed 40 can be replaced. After the connecting column 36 is completely removed from the device, the staff can more easily clean the inside of the device.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
