[0002] A reaction vessel, broadly understood, is a container where physical or chemical reactions occur. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. It is widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries as a pressure vessel to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation.

[0003] Reactors often generate large amounts of waste gas during reactions, which needs to be transported to a purification chamber for treatment to prevent direct dispersion into the air and environmental pollution. However, the above structure has shortcomings. Since activated carbon is often used in the purification chamber to adsorb the waste gas, when the activated carbon reaches saturation and needs to be replaced, the air inlet pipe must be closed, and the adsorption and purification operation can only continue after the activated carbon has been replaced, which affects the waste gas purification efficiency.

[0004] Therefore, it is necessary to provide a new purification reactor for waste gas treatment to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problem that when the activated carbon in a reactor reaches saturation and needs to be replaced during the waste gas purification process, the inlet pipe must be shut off and the adsorption purification operation can only continue after the activated carbon has been replaced, thus affecting the waste gas purification efficiency, this utility model provides a purification reactor for waste gas treatment.

[0012] As a further embodiment of this utility model, a water pump is fixedly installed in the water tank, and a spray pipe is fixedly installed at the bottom of the liquid nitrogen tank. The water outlet of the water pump is fixedly connected to the water inlet of the spray pipe.

[0013] Compared with related technologies, the purification reactor for waste gas treatment provided by this utility model has the following beneficial effects:

[0014] This utility model provides a purification reaction vessel for waste gas treatment:

[0015] 1. The exhaust pipe allows the waste gas from the reactor body to be introduced into the purification box. The liquid nitrogen tank cools the water in the water tank, keeping it at a low temperature. The water tank provides a stable and continuous water source for the nozzles. The arrangement of several nozzles ensures that the waste gas entering the purification box is sufficiently cooled by the cold water. The water also removes some pollutants from the waste gas through its dissolving and adsorption capabilities. The two placement chambers in the fixed box can accommodate two activated carbon boxes. The activated carbon boxes can adsorb some pollutants from the waste gas, further purifying it.

[0016] 2. The support groove provides stable rotation space for the support plate, which can adjust the open state of the activated carbon box. The drive motor provides stable power to drive the rotation of the support plate. The air outlet facilitates the discharge of the waste gas treated by activated carbon adsorption into the purification box. The sealing cover keeps the activated carbon box closed, preventing external moisture from entering and consuming it. At the same time, the support plate can be opened to replace the saturated activated carbon box. The air inlet guides the waste gas into the fixed cylinder, which then facilitates the waste gas entering the corresponding activated carbon box through the open air inlet pipe for adsorption treatment. The sliding port provides sliding space for the slide, which can drive the sealing plug into or out of the air inlet pipe, thereby controlling the closed or open state of the air inlet pipe. This allows for precise introduction of waste gas into any activated carbon box and convenient replacement of the saturated activated carbon box without closing the air inlet channel.

[0017] 3. The guide rod allows the guide plate to slide stably within the drive box. The guide plate controls the sealing plugs on both sides to close or open the air intake pipe on their respective sides, thus facilitating accurate control of the exhaust gas flow direction. The motor continuously provides power, ensuring the cam is stably driven. The cam contacts the guide plate, and under the support of the compression spring, the guide plate remains in contact with the cam, allowing the guide plate to slide stably back and forth along the guide rod, facilitating control of the air intake pipe's opening or closing. The water pump draws cold water from the water tank and delivers it to the nozzles through the spray pipe, thereby cooling and initially treating the exhaust gas entering the purification box.

The purification reactor for waste gas treatment includes: a reactor body 27; an outlet pipe 28, the inlet end of which is threadedly installed at the outlet end of the reactor body 27; a purification tank 1, which is located on one side of the reactor body 27, and the outlet end of the outlet pipe 28 is threadedly connected to the inlet end of the purification tank 1; a liquid nitrogen tank 2, which is fixedly installed on one side inside the purification tank 1; a water tank 3, which is fixedly installed inside the liquid nitrogen tank 2; several nozzles 4, which are located at the bottom of the liquid nitrogen tank 2 and above the inlet of the purification tank 1; and a fixed box 5, which is fixedly installed on the top of the purification tank 1, and contains [missing information]. Two placement chambers; two activated carbon boxes 6, which can be placed in the two placement chambers respectively; the exhaust gas in the reactor body 27 can be introduced into the purification box 1 through the exhaust pipe 28; the liquid nitrogen box 2 can cool the water in the water tank 3, so that the water in the water tank 3 is in a low temperature state; the water tank 3 can provide a stable and continuous water source for the nozzles 4; the arrangement of several nozzles 4 can ensure that the exhaust gas entering the purification box 1 can be fully cooled by the cold water, and can also remove some pollutants in the exhaust gas through the dissolving and adsorption capacity of water; the two placement chambers in the fixed box 5 can be used to accommodate the placement of the two activated carbon boxes 6, which can adsorb some pollutants in the exhaust gas, and further purify the exhaust gas.

[0025] The top of the purification box 1 is provided with a support groove 7, and a support plate 8 is provided in the support groove 7. A drive motor 9 is fixedly installed on the top of the fixed box 5. The output shaft of the drive motor 9 is fixedly connected to the support plate 8. Several air outlets 10 are provided on one side of the support plate 8, and a sealing cover 11 is provided on the opening on the other side of the support plate 8. The support groove 7 provides a stable space for the support plate 8 to rotate. The support plate 8 can adjust the open state of the activated carbon box 6. The drive motor 9 can provide stable power to drive the rotation of the support plate 8. The air outlets 10 facilitate the discharge of the waste gas after being adsorbed by the activated carbon into the purification box 1. The sealing cover 11 can keep the activated carbon box 6 closed when it is not open, preventing external moisture from entering the activated carbon box 6 and consuming it. At the same time, the support plate 8 can be opened to replace the activated carbon box 6 when it is saturated.

[0026] A fixed cylinder 12 is fixedly installed on the top of the liquid nitrogen tank 2. The top of the fixed cylinder 12 is fixedly connected to the fixed box 5. The fixed cylinder 12 has several air inlets 13. Air inlet pipes 14 are fixedly installed on both sides of the fixed cylinder 12. An installation box 15 is fixedly installed on the air inlet side of the placement cavity. The air outlet end of the air inlet pipe 14 is fixedly connected to the air inlet end of the installation box 15. Waste gas can be introduced into the fixed cylinder 12 through the air inlets 13, so that the waste gas can easily enter the corresponding activated carbon box 6 through the open air inlet pipe 14, which facilitates the adsorption treatment of the waste gas.

[0027] The bottom of the mounting box 15 has a sliding opening 16, and a slide 17 is slidably mounted in the mounting box 15. The slide 17 closes the sliding opening 16, and a sealing plug 18 is fixedly installed on one side of the slide 17. The sealing plug 18 can extend into the air inlet pipe 14 and can be used to close the air outlet of the air inlet pipe 14. The sliding opening 16 provides sliding space for the slide 17, and the slide 17 can drive the sealing plug 18 into or out of the air inlet pipe 14, thereby controlling the closed or open state of the air inlet pipe 14. This facilitates the precise introduction of exhaust gas into any activated carbon box 6 and allows for the replacement of the saturated activated carbon box 6 without closing the air inlet channel.

[0028] A drive box 19 is fixedly installed on one inner wall of the purification box 1. A guide rod 20 is fixedly installed in the drive box 19. A guide plate 21 is slidably installed on the guide rod 20. The two sides of the guide plate 21 are fixedly connected to the two slides 17 extending to the outside of the mounting box 15. A compression spring 22 is sleeved on the guide rod 20. The two ends of the compression spring 22 are fixedly connected to the inner wall of the drive box 19 and the guide plate 21, respectively. The guide rod 20 enables the guide plate 21 to slide stably in the drive box 19. The guide plate 21 can control the sealing plugs 18 on both sides to close or open the air inlet pipe 14 on their respective sides, thereby facilitating accurate control of the flow direction of the exhaust gas.

[0029] An adjusting motor 23 is fixedly installed in the drive box 19. A cam 24 is fixedly installed on the output shaft of the adjusting motor 23. The cam 24 is in contact with the guide plate 21. The adjusting motor 23 can continuously provide power so that the cam 24 can be stably driven and can contact the guide plate 21. Under the elastic support of the compression spring 22, the guide plate 21 can always be in contact with the cam 24, thereby realizing the stable back and forth sliding of the guide plate 21 along the guide rod 20, which facilitates the control of the opening or closing of the air intake pipe 14.

[0030] A water pump 25 is fixedly installed in the water tank 3, and a spray pipe 26 is fixedly installed at the bottom of the liquid nitrogen tank 2. The water outlet of the water pump 25 is fixedly connected to the water inlet of the spray pipe 26. The water pump 25 can pump cold water from the water tank 3 and deliver it to the nozzle 4 through the spray pipe 26, thereby achieving cooling and preliminary treatment of the exhaust gas entering the purification box 1.

[0031] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0032] The working principle of the purification reaction vessel for waste gas treatment provided by this utility model is as follows:

[0033] This solution also includes an electrical control cabinet, which is installed on the equipment. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those in the field, so it will not be described in detail here.

[0034] In use, the exhaust gas in the main body 27 of the reactor enters the purification box 1 through the exhaust pipe 28. The water pump 25 pumps cold water from the water tank 3 and delivers it to the spray pipe 26, and then sprays it out through the nozzle 4. This can reduce the temperature of the exhaust gas entering the purification box 1, and can also remove some pollutants in the exhaust gas through the dissolving and adsorption capacity of water. The remaining exhaust gas continues to flow upward and enters the fixed cylinder 12 through the air inlet 13. Then, it flows into the corresponding activated carbon box 6 through the air inlet pipe 14 which is not sealed by the sealing plug 18. After the exhaust gas has adsorbed some pollutants by the activated carbon, it continues to flow upward and flows out through the air outlet 10 located above the activated carbon box 6.

[0035] When the activated carbon in the activated carbon box 6 on this side reaches saturation, the regulating motor 23 is started, causing the regulating motor 23 to drive the cam 24 to rotate. Under the elastic support of the compression spring 22, the guide plate 21 is driven to slide to one side along the guide rod 20 with the cam 24, causing the slides 17 on both sides to slide to the same side, causing the sealing plug 18 located in the rotation direction to leave the air inlet pipe 14 on this side, so that the air inlet pipe 14 on this side enters the open state. Similarly, the sealing plug 18 on the other side is driven into the air inlet pipe 14 on this side, so that the air inlet pipe 14 on this side is closed, and then the exhaust gas can enter the corresponding activated carbon box 6 through the open side air inlet pipe 14.

[0036] While the regulating motor 23 is starting, the drive motor 9 is also driven, causing the support plate 8 to rotate along the support groove 7, so that the air outlet 10 rotates to the same side as the open air inlet pipe 14, so that the exhaust gas entering this side can be discharged through the air outlet 10 after being adsorbed by the activated carbon. At the same time, the closed cover 11 on the other side can be opened to replace the activated carbon box 6 on this side.

[0037] Compared with related technologies, the purification reactor for waste gas treatment provided by this utility model has the following beneficial effects:

[0038] This utility model provides a purification reactor for waste gas treatment. Waste gas from the reactor body 27 can be introduced into a purification chamber 1 via an outlet pipe 28. A liquid nitrogen tank 2 cools the water in a water tank 3, keeping the water at a low temperature. The water tank 3 provides a stable and continuous water source for the nozzles 4. The arrangement of several nozzles 4 ensures that the waste gas entering the purification chamber 1 is sufficiently cooled by the cold water, and that some pollutants in the waste gas are removed through the dissolving and adsorption capabilities of water. Two placement chambers in the fixed box 5 can accommodate two activated carbon boxes 6, which can remove some pollutants from the waste gas. The activated carbon box 6 undergoes adsorption treatment to further purify the waste gas. The support groove 7 provides stable space for the support plate 8 to rotate, and the support plate 8 can adjust the open / closed state of the activated carbon box 6. The drive motor 9 provides stable power to drive the rotation of the support plate 8. The exhaust port 10 facilitates the discharge of the waste gas treated by activated carbon adsorption into the purification box 1. The sealing cover 11 keeps the activated carbon box 6 closed, preventing external moisture from entering and consuming it. Simultaneously, the support plate 8 can be opened to replace the saturated activated carbon box 6. The exhaust gas can be introduced into the fixed cylinder 12 through the air inlet 13. This allows exhaust gas to easily enter the corresponding activated carbon box 6 through the open intake pipe 14, facilitating adsorption treatment. The sliding port 16 provides sliding space for the slide frame 17, which can move the sealing plug 18 into or out of the intake pipe 14, thus controlling the closed or open state of the intake pipe 14. This allows for precise and convenient introduction of exhaust gas into any activated carbon box 6, facilitating replacement of a saturated activated carbon box 6 without closing the intake channel. The guide rod 20 allows the guide plate 21 to slide stably within the drive box 19, and the guide plate 21 controls the sealing plugs 18 on both sides to align with their respective sides. The intake pipe 14 can be closed or opened to facilitate accurate control of the flow direction of exhaust gas. The motor 23 can continuously provide power to drive the cam 24 stably. The cam 24 can contact the guide plate 21. Under the elastic support of the compression spring 22, the guide plate 21 can always contact the cam 24, so that the guide plate 21 can slide back and forth stably along the guide rod 20, which facilitates the control of the opening or closing of the intake pipe 14. The water pump 25 can pump cold water from the water tank 3 and deliver it to the nozzle 4 through the spray pipe 26, thereby achieving the cooling and preliminary treatment of the exhaust gas entering the purification box 1.
