Description

Technical Field

[0001] The invention belongs to the technical direction of incinerators, and specifically relates to an RTO regenerative heat incinerator. Background Art

[0002] Regenerative Thermal Oxidizer, also known as Regenerative Thermal Oxidizer, is abbreviated as RTO. Its principle is to heat the organic waste gas to above 760 degrees Celsius, so that the VOC in the waste gas is oxidized and decomposed into carbon dioxide and water. The high-temperature gas produced by oxidation flows through a special ceramic heat storage body, so that the ceramic body heats up and "storages heat". This "heat storage" is used to preheat the subsequent organic waste gas, thereby saving the fuel consumption of waste gas heating. The ceramic heat storage body should be divided into two (including two) or more areas or chambers. Each heat storage chamber undergoes heat storage-heat release-cleaning procedures in turn, over and over again, and works continuously. After the heat storage chamber "releases heat", part of the clean exhaust gas that has been treated and qualified should be immediately introduced to clean the heat storage chamber (to ensure that the VOC removal rate is above 95%). Only after the cleaning is completed can the "heat storage" procedure be entered.

[0041] Heat recovery operation:

[0042] When the staff needs to use the RTO regenerative incinerator 1 for production operation, the staff first turns on the power of the workshop. At this time, the RTO regenerative incinerator 1 is started, and the equipment program is started. The equipment program detects the temperature in the exhaust box 2 through three groups of temperature sensors 26 and compares it with the set value. The equipment program sets the temperature value to M1, M2, and M3, M1 is the minimum value, and M3 is the maximum value, which 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, N1 is the minimum value, and N2 is the maximum value, which can be adjusted according to specific needs. When the equipment program detects that the temperature value is M1, the equipment program determines that the temperature of the gas discharged from the RTO regenerative incinerator 1 is low and the waste heat cannot be recovered. The equipment program controls the first electric fan blade 313 not to open, and the gas discharged from the RTO regenerative incinerator 1 is discharged from the air inlet pipe 21 into the exhaust box 2, and is initially filtered by the filter screen plate 25 and then transported to the second air outlet pipe 24, and then discharged into the subsequent gas treatment device for treatment;

[0043] When the temperature value detected by the equipment program is M2, the equipment program determines that the gas discharged from the RTO thermal storage incinerator 1 is hot and can be heat recovered. The equipment program controls the first electric fan blade 313 to open, and the opening value is N1. The first electric fan blade 313 opens to the minimum value, and the second electric fan blade 37 is in a closed state. The gas discharged from the RTO thermal storage incinerator 1 is discharged into the exhaust box 2 from the air inlet pipe 21, and is transported backward after preliminary filtration by the filter screen 25. At this time, the warm gas is diverted into the heat collecting pipe 312 through the first electric fan blade 313. The warm gas heats the first heat conducting rod 319, and the first heat conducting rod 319 conducts heat to the cleaning liquid in the cleaning water tank 31 to heat it and improve the subsequent cleaning efficiency. In the process of exhausting air, the warm gas will blow the two sets of rotating blades 316 to rotate, and the two sets of rotating blades 316 drive the two sets of stirring rods 317 to rotate, and stir the cleaning liquid stored in the cleaning water tank 31, so that it is heated evenly, thereby 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 RTO thermal storage incinerator 1 is high-temperature gas, and heat can be recovered from it. The equipment program controls the opening value of the first electric fan blade 313 to be adjusted to N2, and the first electric fan blade 313 is opened to the maximum value. The gas discharged from the RTO thermal storage incinerator 1 is discharged from the air inlet pipe 21 into the exhaust box 2, and is transported backward after preliminary filtration by the filter screen 25. At this time, the warm gas is diverted into the heat collecting pipe 312 through the first electric fan blade 313, and the warm gas heats the first heat conducting rod 319. The first heat conducting rod 319 conducts heat to the cleaning liquid in the cleaning water tank 31 to heat it and improve the subsequent cleaning efficiency. In the process of exhausting air, the warm gas will blow the two sets of rotating blades 316 to rotate, and the two sets of rotating blades 316 drive the two sets of stirring rods 317 to rotate, and stir the cleaning liquid stored in the cleaning water tank 31, so that it is heated evenly, thereby improving the heating efficiency of the cleaning liquid;

[0045] By using the first electric fan blade 313, the temperature sensor 26 and the equipment program in coordination, the heat recovery method can be changed according to the different exhaust gas temperatures. When the exhaust gas temperature is low, no heat recovery operation is performed and the exhaust gas is directly discharged to the subsequent gas processing device, thereby reducing energy consumption and achieving the effect of energy conservation and emission reduction. When the exhaust gas temperature is high, the opening value of the first electric fan blade 313 is changed to change the air intake volume of the hot gas, and the waste heat of the hot gas is recovered for heating the cleaning water. There is no need to use an additional heating device, thereby reducing energy consumption and reducing the production cost of the factory. By using two sets of rotating paddles and two sets of stirring rods 317 in coordination, the hot gas can be used to drive the two sets of stirring rods 317 to rotate while exhausting the air to stir the cleaning liquid stored in the cleaning water tank 31, thereby improving the heating efficiency of the cleaning liquid and allowing it to be heated evenly.

[0046] Preheating operation:

[0047] In the process of performing the above operations, the equipment program controls the preheating operation. When the equipment program detects that the temperature value of the three groups of temperature sensors 26 is M2, the equipment program determines that the gas discharged from the RTO regenerative incinerator 1 is hotter and can be used for preheating. The equipment program controls the second electric fan blade 37 to open, and the opening value is N1. The first electric fan blade 313 is in a closed state. In the process of exhausting the exhaust box 2, the hot gas will pass through several groups of second heat conducting rods 361. At this time, several groups of second heat conducting rods 361 will 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. In the process of exhausting, 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 circulate to the air inlet of the RTO regenerative incinerator 1, and the air inhaled by the RTO regenerative incinerator 1 will be preheated to improve the production efficiency of the RTO regenerative incinerator 1;

[0048] When the equipment program detects that the temperature value of the three groups of temperature sensors 26 is M3, the equipment program determines that the gas discharged from the RTO regenerative incinerator 1 is high-temperature gas, which 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 a closed state. During the exhaust process of the exhaust box 2, the hot gas will pass through a plurality of groups of second heat conducting rods 361. At this time, the plurality of groups of second heat conducting 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 circulate to the air inlet of the RTO regenerative incinerator 1, and the air inhaled by the RTO regenerative incinerator 1 will be preheated to improve the production efficiency of the RTO regenerative incinerator 1;

[0049] By using three groups of temperature sensors 26, the second electric fan blades 37 in coordination with the equipment program, the preheating mode can be changed according to the different exhaust gas temperatures, and the exhaust high-temperature gas can be used for a second time to heat the chamber. When the exhaust gas temperature is low, the opening value of the second electric fan blades 37 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 blades 37 is increased to increase the air intake, accelerate the blowing of hot gas, improve the preheating efficiency, and improve the production efficiency of the factory.

[0050] Cleaning operation:

[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, T1 is the minimum value, T2 is the maximum value, and can be adjusted according to specific needs. The second electric fan blade 37 is in a closed state, and the speed of the motor 332 is V1 and V2, V1 is the minimum value, and V2 is the maximum value, which can be adjusted according to specific needs. When the equipment program checks that the temperature value of the three groups of temperature sensors is M2, the equipment program determines that the temperature of the exhaust gas is low and the temperature of the cleaning liquid is not high. The equipment program controls the water pump 321 to start, the two groups of electric valves to start, the motor 332 to start, the speed is V2, and the cleaning liquid in the cleaning water tank 31 is turned on. It will also be sprayed from two groups of cleaning nozzles. The first cleaning nozzle 318 sprays the cleaning liquid obliquely downward to the surface of the filter screen plate 25 to clean the smoke and dust adhering to the surface of the filter screen plate 25. The second cleaning nozzle 322 sprays the cleaning liquid to the surface of the partition 36 to clean it. The motor 332 drives the first cleaning brush cylinder 33 to rotate rapidly, and the transmission belt 34 drives the second cleaning brush cylinder 35 to rotate rapidly. The two groups of cleaning brush cylinders use the cleaning liquid to brush away the smoke and dust deposited on the bottom of the partition 36. The equipment program sets the cleaning time to T1. When the T1 time is up, the equipment program controls the built-in drainage valve of the drain pipe 23 to open, and discharges the waste water generated by cleaning to the external sewage collection device;

[0052] When the equipment program checks that the temperature value of the three groups of temperature sensors is M3, the equipment program determines that the temperature of the exhaust gas is high and the temperature of the cleaning liquid is high. The equipment program controls the water pump 321 to start, the two groups of electric valves to start, the motor 332 to start, the speed is V1, and the cleaning in the cleaning water tank 31 will also be sprayed out from the two groups of cleaning nozzles. The first cleaning nozzle 318 sprays the cleaning liquid obliquely downward to the surface of the filter screen plate 25 to wash away the smoke and dust adhering to the surface of the filter screen plate 25. The second cleaning nozzle 322 sprays the cleaning liquid to 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 groups of cleaning brush cylinders use the cleaning liquid to brush away the smoke and dust deposited on the bottom of the partition 36. The equipment program sets the cleaning time to T1. When the T1 time is up, the equipment program controls the built-in drainage valve of the drain pipe 23 to open, and discharges the wastewater generated by cleaning to the external sewage collection device;

[0053] By using two groups of cleaning nozzles, two groups of cleaning brush cylinders and equipment programs in coordination, the cleaning speed can be changed according to the different temperatures of the cleaning liquid. When the temperature of the cleaning liquid is not high, the two groups of cleaning brush cylinders are rotated quickly to increase the cleaning speed and avoid the accumulation of stubborn smoke and dust. There is no need to manually clean the filter screen plate 25, which reduces the labor intensity of the staff. When the temperature of the cleaning liquid is high, the two groups of cleaning brush cylinders are rotated slowly to improve the cleaning efficiency and avoid the accumulation of oil stains generated by processing at the bottom of the exhaust box 2 to affect normal use. There is no need for manual cleaning by the staff, which improves the cleaning efficiency of the factory and the safety factor of the factory during production.
