Description

Technical Field

[0001] This invention belongs to the field of incinerator technology, specifically relating to an RTO regenerative thermal oxidizer. Background Technology

[0002] A regenerative thermal oxidizer (RTO) works by heating organic waste gas to over 760 degrees Celsius, causing VOCs in the waste gas to oxidize and decompose into carbon dioxide and water. The high-temperature gas produced by oxidation flows through a specially designed ceramic heat storage body, which heats the ceramic body and stores heat. This stored heat is used to preheat the organic waste gas that enters later, thus saving fuel consumption for heating the waste gas. The ceramic heat storage body should be divided into two or more zones or chambers. Each heat storage chamber undergoes a heat storage-heat release-cleaning process in sequence, working continuously. After the heat storage chamber releases heat, a portion of the treated clean exhaust gas should be introduced immediately to clean the heat storage chamber (to ensure that the VOC removal rate is above 95%). Only after cleaning is completed can the heat storage process begin.

[0003] An existing patent publication number CN 219473685 U discloses an RTO regenerative thermal oxidizer, which includes a combustion furnace body. The bottom of both ends of the combustion furnace body is respectively connected to a gas filter box and a cooling box. The top of the combustion furnace body is also connected to a gas pipe. The gas pipe extends into the combustion furnace body and is provided with a combustion head. The combustion head is provided with multiple combustion nozzles. The multiple combustion nozzles are installed radially on the combustion head. It can only filter organic gases and ensure their complete combustion. However, it cannot be cleaned quickly after use, and the production efficiency is not high. Some improvements are needed.

[0008] The present invention further describes that two sets of first mounting base arrays are installed inside the top of the exhaust box, corresponding to the position of the cleaning water tank. Two sets of rotating rods are set on the two sets of first mounting bases. Two sets of rotating blades are detachably installed on one end of the two sets of rotating rods. The two sets of rotating blades are located inside the exhaust box. Two sets of stirring rods are detachably installed on the other end of the two sets of rotating rods. The two sets of stirring rods are located inside the cleaning water tank. The first cleaning nozzle is fixedly installed inside one end of the exhaust box, located on one side of the two sets of moving slide rails. The cleaning water tank has a built-in water supply pipe connected to the first cleaning nozzle. Several sets of first heat conducting rods are fixedly installed in the heat collection tube.

[0013] The present invention further illustrates that the furnace body is placed on the floor of the production workshop.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention, through the combined use of the first electric fan blade, temperature sensor and equipment program, can change the heat recovery method according to the different temperatures of the exhaust gas. When the exhaust gas temperature is low, no heat recovery operation is performed, and it is directly discharged into the subsequent gas treatment device, reducing energy consumption and achieving the effect of energy saving and emission reduction. When the exhaust gas temperature is high, the opening value of the first electric fan blade is changed to change the air intake of hot air, and the waste heat of the hot air is recovered for heating the cleaning water. No additional heating device is required, reducing energy consumption and lowering the production cost of the factory. Through the combined use of two sets of rotating blades and two sets of stirring rods, the hot air can be used to drive the two sets of stirring rods to rotate while exhausting air, thereby stirring the cleaning liquid stored in the cleaning water tank, improving the heating efficiency of the cleaning liquid, and ensuring that it is heated evenly.

[0015] By using three sets of temperature sensors, a second electric fan blade, and the equipment program in conjunction, the preheating method can be changed according to the temperature of the exhaust gas. The high-temperature exhaust gas can also be used for secondary heating of the chamber. When the exhaust gas temperature is low, the opening value of the second electric fan blade is reduced to reduce the air intake, thereby accelerating the accumulation of heat and increasing the preheating temperature. When the exhaust gas temperature is high, the opening value of the second electric fan blade is increased to increase the air intake, accelerate the blowing out of hot gas, improve preheating efficiency, and improve the production efficiency of the factory.

[0016] By using two sets of cleaning nozzles and two sets of cleaning brushes in conjunction with the equipment program, the cleaning speed can be adjusted according to the temperature of the cleaning solution. When the temperature of the cleaning solution is not high, the two sets of cleaning brushes rotate quickly to increase the cleaning speed and prevent the accumulation of stubborn dust. This eliminates the need for manual cleaning of the filter screen and reduces the labor intensity of the workers. When the temperature of the cleaning solution is high, the two sets of cleaning brushes rotate slowly to improve the cleaning efficiency and prevent the oil stains generated during processing from accumulating at the bottom of the exhaust box, affecting normal use. This also eliminates the need for manual cleaning by the workers, improving the cleaning efficiency of the factory and increasing the safety factor during factory production.

[0038] The exhaust box 2 is powered by an external workshop power supply to drive its internal components, and the furnace body 1 is powered by an external workshop power supply.

[0039] The exhaust box 2 is also equipped with a program that can control the opening and closing of two sets of electric fan blades, the start and stop of water pump 321, the start and stop of motor 332, the opening and closing of two sets of electric valves, and the opening and closing of the drain valve built into drain pipe 23.

[0040] The two sets of electric fan blades, water pump 321, motor 332, two sets of electric valves, and drain pipe 23 with built-in drain valve are all connected to the equipment program signal.

[0041] Heat recovery operation:

[0042] When staff need to use the RTO regenerative thermal oxidizer for production operations, they first turn on the workshop power. At this time, the furnace body 1 starts up, and the equipment program starts up. The equipment program detects the temperature in the exhaust box 2 through three sets of temperature sensors 26 and compares it with the set value. The equipment program sets the temperature values ​​to M1, M2, and M3, where M1 is the minimum value and M3 is the maximum value. These values ​​can be adjusted according to specific needs. The opening values ​​of the first electric fan blade 313 and the second electric fan blade 37 are N1 and N2, respectively, where N1 is the minimum value and N2 is the maximum value. These values ​​can also be adjusted according to specific needs. When the equipment program detects a temperature value of M1, it determines that the gas temperature discharged from the furnace body 1 is too low to recover waste heat. The equipment program controls the first electric fan blade 313 not to open, and the gas discharged from the furnace body 1 is discharged into the exhaust box 2 from the air inlet pipe 21. After preliminary filtration by the filter screen 25, it is conveyed to the second air outlet pipe 24 and then discharged into the subsequent gas treatment device for further processing.

[0043] When the temperature value detected by the equipment program is M2, the equipment program determines that the gas discharged from the furnace body 1 is relatively hot and can be recovered. The equipment program controls the first electric fan blade 313 to open, with the opening value being N1. The first electric fan blade 313 is opened to its minimum value, while the second electric fan blade 37 is in the closed state. The gas discharged from the furnace body 1 is discharged into the exhaust box 2 from the air inlet pipe 21. After preliminary filtration by the filter screen plate 25, it is transported backward. At this time, the warm gas is diverted into the heat collection pipe 312 by the first electric fan blade 313. The warm gas heats the first heat conduction rod 319, which conducts heat to the cleaning liquid in the cleaning water tank 31, heating it and improving the subsequent cleaning efficiency. During the exhaust process, the warm gas blows two sets of rotating blades 316 to rotate. The two sets of rotating blades 316 drive two sets of stirring rods 317 to rotate, stirring the cleaning liquid stored in the cleaning water tank 31, making it heated evenly and improving the heating efficiency of the cleaning liquid.

[0044] When the temperature value detected by the equipment program is M3, the equipment program determines that the gas discharged from the furnace body 1 is high-temperature gas and can recover heat from it. The equipment program controls the opening value of the first electric fan blade 313 to be adjusted to N2, the maximum opening value of the first electric fan blade 313. The gas discharged from the furnace body 1 is discharged into the exhaust box 2 from the air inlet pipe 21. After preliminary filtration by the filter screen plate 25, it is transported backward. At this time, the warm gas is diverted into the heat collection tube 312 through the first electric fan blade 313. The warm gas heats the first heat conduction rod 319. The first heat conduction rod 319 conducts heat to the cleaning liquid in the cleaning water tank 31, heating it and improving the subsequent cleaning efficiency. During the exhaust process, the warm gas blows the two sets of rotating blades 316 to rotate. The two sets of rotating blades 316 drive the two sets of stirring rods 317 to rotate, stirring the cleaning liquid stored in the cleaning water tank 31, making it heated evenly and improving the heating efficiency of the cleaning liquid.

[0045] By using the first electric fan blade 313, temperature sensor 26, and equipment program in conjunction with each other, the heat recovery method can be changed according to the temperature of the exhaust gas. When the temperature of the exhaust gas is low, no heat recovery operation is performed, and the gas is directly discharged into the subsequent gas treatment device, reducing energy consumption and achieving energy saving and emission reduction. When the temperature of the exhaust gas is high, the opening value of the first electric fan blade 313 is changed to change the air intake of the hot air, and the waste heat of the hot air is recovered for heating the cleaning water. No additional heating device is needed, reducing energy consumption and lowering the production cost of the factory. By using two sets of rotating blades and two sets of stirring rods 317 in conjunction with each other, the hot air can be used to drive the two sets of stirring rods 317 to rotate while exhausting the air, thereby stirring the cleaning liquid stored in the cleaning water tank 31, improving the heating efficiency of the cleaning liquid, and ensuring that it is heated evenly.

[0046] Preheating process:

[0047] During the above operations, the equipment program controls the preheating operation. When the equipment program detects that the temperature value of the three sets of temperature sensors 26 is M2, the equipment program determines that the gas discharged from the furnace body 1 is hot and can be used for preheating. The equipment program controls the second electric fan blade 37 to open with an opening value of N1, while the first electric fan blade 313 is in the closed state. During the exhaust process of the exhaust box 2, the hot air will pass through several sets of second heat conduction rods 361. At this time, the several sets of second heat conduction rods 361 conduct the heat in the hot air to the heating chamber 39, using the heat in the gas to heat the inside of the heating chamber 39. During the exhaust process, the gas in the exhaust box 2 will be diverted to the third air outlet pipe 371 through the second electric fan blade 37, and then blown downward into the heating chamber 39. At this time, the hot air will flow into the first air outlet pipe 22, and then flow to the air inlet of the furnace body 1 to preheat the air drawn into the furnace body 1, thereby improving the production efficiency of the furnace body 1.

[0048] When the equipment program detects that the temperature value of the three sets of temperature sensors 26 is M3, the equipment program determines that the gas discharged from the furnace body 1 is high-temperature gas and can be used for preheating. The equipment program controls the opening value of the second electric fan blade 37 to be adjusted to N2, and the first electric fan blade 313 is in the closed state. During the exhaust process of the exhaust box 2, the hot gas will pass through several sets of second heat conduction rods 361. At this time, the several sets of second heat conduction rods 361 conduct the heat in the hot gas to the heating chamber 39, and use the heat in the gas to heat the inside of the heating chamber 39. During the exhaust process, the gas in the exhaust box 2 will be diverted to the third air outlet pipe 371 through the second electric fan blade 37, and then blown downward into the heating chamber 39. At this time, the hot gas will flow into the first air outlet pipe 22, and then flow to the air inlet of the furnace body 1 to preheat the air drawn into the furnace body 1 and improve the production efficiency of the furnace body 1.

[0049] By using three sets of temperature sensors 26, the second electric fan blade 37, and the equipment program in conjunction with each other, the preheating method can be changed according to the different temperatures of the discharged gas. The high-temperature discharged gas can also be used for secondary heating of the chamber. When the temperature of the discharged gas is low, the opening value of the second electric fan blade 37 is reduced to reduce the air intake, thereby accelerating the accumulation of heat and increasing the preheating temperature. When the temperature of the discharged gas is high, the opening value of the second electric fan blade 37 is increased to increase the air intake, accelerate the blowing out of hot gas, improve the preheating efficiency, and improve the production efficiency of the factory.

[0050] Cleaning procedure:

[0051] After completing the production operation, the staff performs the cleaning operation through the equipment program control. The equipment program sets the cleaning time to T1 and T2, where T1 is the minimum value and T2 is the maximum value, which can be adjusted according to specific needs. The second electric fan blade 37 is in the off state, and the speed of motor 332 is set to V1 and V2, where V1 is the minimum value and V2 is the maximum value, which can be adjusted according to specific needs. When the equipment program detects that the temperature value of the three sets of temperature sensors is M2, the equipment program determines that the temperature of the discharged gas is low and the temperature of the cleaning fluid is not high. The equipment program controls the water pump 321 to start, the two sets of electric valves to open, and the motor 332 to start at a speed of V2, cleaning the water in the cleaning tank 31. It will also spray from two sets of cleaning nozzles. The first cleaning nozzle 318 sprays the cleaning liquid obliquely downwards onto the surface of the filter screen 25 to wash away the dust adhering to the surface of the filter screen 25. The second cleaning nozzle 322 sprays the cleaning liquid onto the surface of the partition 36 to clean it. The motor 332 drives the first cleaning brush cylinder 33 to rotate quickly, and the transmission belt 34 drives the second cleaning brush cylinder 35 to rotate quickly. The two sets of cleaning brush cylinders clean the dust deposited at the bottom of the partition 36 with the cleaning liquid. The equipment program sets the cleaning time to T1. When T1 time is up, the equipment program controls the drain valve built into the drain pipe 23 to open and discharge the wastewater generated during cleaning to the external sewage collection device.

[0052] When the equipment program detects that the temperature value of the three temperature sensors is M3, the equipment program determines that the temperature of the discharged gas is high and the temperature of the cleaning fluid is high. The equipment program controls the water pump 321 to start, the two sets of electric valves to start, and the motor 332 to start at a speed of V1. The cleaning fluid in the cleaning water tank 31 will also be sprayed out from the two sets of cleaning nozzles. The first cleaning nozzle 318 sprays the cleaning fluid obliquely downward onto the surface of the filter screen 25 to wash away the dust adhering to the surface of the filter screen 25. The second cleaning nozzle 322 sprays the cleaning fluid onto the surface of the partition 36 to clean it. The motor 332 drives the first cleaning brush cylinder 33 to rotate slowly, and the transmission belt 34 drives the second cleaning brush cylinder 35 to rotate slowly. The two sets of cleaning brush cylinders clean the dust deposited at the bottom of the partition 36 with the cleaning fluid. The equipment program sets the cleaning time to T1. When T1 time is up, the equipment program controls the drain valve built into the drain pipe 23 to open and discharge the wastewater generated during cleaning to the external sewage collection device.

[0053] By using two sets of cleaning nozzles, two sets of cleaning brushes, and the equipment program in conjunction with each other, the cleaning speed can be adjusted according to the temperature of the cleaning solution. When the temperature of the cleaning solution is not high, the two sets of cleaning brushes rotate quickly to increase the cleaning speed and prevent the accumulation of stubborn dust. This eliminates the need for manual cleaning of the filter screen 25, reducing the labor intensity of the workers. When the temperature of the cleaning solution is high, the two sets of cleaning brushes rotate slowly to improve the cleaning efficiency and prevent the oil stains generated during processing from accumulating at the bottom of the exhaust box 2, affecting normal use. This also eliminates the need for manual cleaning by the workers, improving the cleaning efficiency of the factory and increasing the safety factor during factory production.
