Description

Technical Field

[0001] This utility model relates to the technical field of RCO catalytic combustion equipment, and in particular to an RCO catalytic combustion equipment that utilizes waste heat. Background Technology

[0002] RCO catalytic combustion equipment is an organic waste gas treatment device that combines low-temperature catalytic oxidation with heat storage technology. It is used for the treatment of medium and high concentration organic waste gas purification. RCO regenerative catalytic combustion equipment is developed based on RTO regenerative incineration equipment. A catalyst is arranged on the heat storage ceramic layer of the heat storage equipment, so that the incoming waste gas is catalytically burned and decomposed into carbon dioxide and water at 200℃-400℃, thereby achieving the purpose of purifying waste gas.

[0003] During catalytic combustion, organic waste gas is oxidized and decomposed under the action of a catalyst, generating carbon dioxide and water vapor and releasing a large amount of heat energy. The heat exchanger utilizes the heat from this high-temperature purified gas to preheat the fresh waste gas entering the equipment, bringing its temperature close to the temperature required for the catalytic reaction. RCO equipment is usually equipped with a heat storage ceramic body. The heat exchanger and the heat storage ceramic body work together. When the high-temperature purified gas passes through the heat storage ceramic body, the heat is absorbed and stored by the ceramic body. When the low-temperature waste gas enters the equipment, the heat storage ceramic body releases heat to preheat the waste gas. The heat exchanger optimizes the airflow path and heat transfer efficiency to ensure efficient heat transfer between the heat storage ceramic body and the waste gas, forming a continuous heat energy cycle.

[0004] While traditional heat exchangers can preheat low-temperature exhaust gases to a certain extent, they are limited in the precision of heat energy utilization. They cannot fully capture and recycle the residual heat after the reaction, resulting in a large amount of heat being lost invisibly, causing a hidden waste of energy. Utility Model Content

[0030] Example:

[0031] Reference Figures 1-7A waste heat recovery catalytic combustion (RCO) device includes an adsorption bed 1 equipped with a filter box 2, a desorption system 3, a catalytic combustion furnace 4, and an exhaust system 5. The outlet of the adsorption bed 1 is fixedly connected to the inlet of the desorption system 3, and the outlet of the desorption system 3 is fixedly connected to the inlet of the catalytic combustion furnace 4. The device also includes a guide shell 6, fixedly connected to the outlet of the catalytic combustion furnace 4. A spiral blade 14 is fixedly connected inside the guide shell 6. When gas from the catalytic combustion furnace 4 enters the guide shell 6, the spiral blade 14 guides the gas, reducing the gas velocity and improving the water-liquid heat exchange quality. The inlet of the exhaust system 5 is fixedly connected to the inner cavity of the guide shell 6. A water storage tank 7 is fixedly connected inside the guide shell 6. A fixed... The filter box 2 is connected to an outlet pipe 8 and an inlet pipe 15. An electromagnetic valve is fixedly fitted on the inlet pipe 15. The water storage tank 7 is equipped with a drive component to control the movement of the water. A ventilation box 9 is fixedly connected to the air outlet end of the filter box 2. The side of the ventilation box 9 away from the filter box 2 is fixedly connected to the air inlet end of the adsorption bed 1. A water guide shell 10, which is fixedly connected to the outlet pipe 8, is fixedly installed inside the ventilation box 9. The water guide shell 10 is made of metal and has an S-shaped groove inside. When gas enters the ventilation box 9 through the filter box 2, the air velocity can be reduced under the guidance of the S-shaped groove, so that the water guide shell 10 can heat the air evenly. A drain pipe 11 is fixedly connected to the side of the water guide shell 10 away from the outlet pipe 8. Electromagnetic valves are fixedly fitted on both the outlet pipe 8 and the drain pipe 11.

[0032] Specifically, by setting up the air guide shell 6, the heat of the gas can be introduced into the water storage tank 7 to heat the water inside. Then, the hot water is used to preheat the low-temperature exhaust gas, realizing the recovery and utilization of waste heat. In addition, during the continuous heat exchange process, the hot water inside the water guide shell 10 is discharged through the drain pipe 11, which can also be used for heating the factory, avoiding hidden energy waste.

[0033] The driving component includes: a housing 12, which is fitted onto the outside of the water storage tank 7, wherein a support base 121 is fixedly connected inside the housing 12, and both ends of the water storage tank 7 are fixedly connected to the support base 121 and the housing 12 respectively; a motor 122 fixedly installed on the support base 121, wherein the output end of the motor 122 passes through the water storage tank 7 and is fixedly connected to a stirring rod 123, a sealed bearing is fixedly fitted on the output end of the motor 122, the outer ring of the sealed bearing is fixedly connected to the water storage tank 7, and an adjusting component is provided on the housing 12 to apply pressure to the inside of the water storage tank 7 and cause the water inside the water storage tank 7 to flow out.

[0034] Specifically, by setting a driving component, when the output end of the motor 122 drives the stirring rod 123 to rotate, it can stir the water inside the water storage tank 7, thereby improving the heating quality of the water.

[0035] The adjusting component includes a hydraulic cylinder 13 fixedly installed on the housing 12. The output end of the hydraulic cylinder 13 extends into the water storage tank 7 and is fixedly connected to a piston plate 131. The piston plate 131 is slidably connected inside the water storage tank 7.

[0036] Specifically, by setting an adjusting component, when the hot water inside the water storage tank 7 is discharged, the output end of the hydraulic cylinder 13 drives the piston plate 131 to move downward, and uses pressure to push the hot water to the drain pipe 11. After the discharge is completed, the solenoid valve on the drain pipe 11 is closed and the solenoid valve on the inlet pipe 15 is opened. The upward negative pressure of the piston plate 131 can achieve the function of automatic water replenishment.

[0037] The surface of the water outlet pipe 8 is fixedly covered with an insulation sleeve, and the insulation sleeve is made of glass wool.

[0038] Specifically, the insulation sleeve made of glass wool has an extremely low thermal conductivity, which can effectively prevent heat transfer, ensure the temperature of the medium inside the pipe is stable, reduce energy loss, and thus improve the insulation performance of the outlet pipe 8.

[0039] Working principle: During catalytic combustion, organic waste gas is oxidized and decomposed under the action of a catalyst, generating carbon dioxide and water vapor, and releasing a large amount of heat energy. Part of the heat enters the adsorption bed 1 through the catalytic combustion furnace 4 to desorb activated carbon, and the other part of the heat enters the air guide shell 6 and flows downward along the spiral blades 14 to heat the water storage tank 7. During the heating process, the operator starts the motor 122 using an external control switch. The output end of the motor 122 drives the stirring rod 123 to rotate, which can stir the water inside the water storage tank 7, making it evenly heated.

[0040] Once the water inside the storage tank 7 is heated to the designated temperature, the operator opens the solenoid valve on the outlet pipe 8 and activates the hydraulic cylinder 13. The output end of the hydraulic cylinder 13 drives the piston plate 131 to move downwards, squeezing the water and forcing it through the outlet pipe 8 into the guide shell 10. Because the guide shell 10 has an S-shaped groove inside, the low-temperature exhaust gas filtered by the filter box 2 flows downwards along the S-shaped groove when it enters the ventilation box 9. At this time, the heat from the hot water inside the guide shell 10 can preheat the low-temperature exhaust gas.

[0041] During continuous heat exchange, the operator closes the solenoid valve on the outlet pipe 8 and opens the solenoid valve on the inlet pipe 15. At this time, the output end of the hydraulic cylinder 13 drives the piston plate 131 to move upward. The negative pressure inside the water storage tank 7 draws the water in the inner cavity of the inlet pipe 15 into the water storage tank 7, realizing automatic water replenishment. Furthermore, during continuous heat exchange, the water inside the water guide shell 10 still has a temperature. By draining the water inside the water guide shell 10, it can also provide heating for the factory.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
