Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of waste gas incinerator technology, and more specifically, to a waste gas incinerator for the production of insulation boards. Background Technology

[0002] During the production of insulation boards, the volatilization or reaction of raw materials will generate waste gas containing harmful substances such as volatile organic compounds, formaldehyde, and phenols. If these waste gases are directly emitted, they will not only pollute the environment but may also harm human health. Therefore, the waste gases need to be incinerated in an incinerator to decompose the harmful substances into harmless substances through high-temperature combustion, while simultaneously achieving energy recovery and compliance with emission standards.

[0003] When incinerating waste gas, the waste gas is introduced into the incinerator. Through high-temperature oxidation, the organic pollutants and some inorganic harmful substances in the waste gas are decomposed into harmless and stable products. At the same time, the exhaust gas is treated by heat recovery or direct emission.

[0004] During incineration, oxygen and other combustion-supporting air are usually introduced into the incinerator through a blower to directly replenish the oxygen required for the reaction, ensuring that elements such as carbon and hydrogen in the material are fully oxidized and improving combustion efficiency. When introducing the air, pipes are usually run through the top or side of the incinerator to allow the air to mix with the exhaust gas. However, since the air is sprayed directly from the outlet, it is difficult to mix the exhaust gas in different parts of the incinerator, which may result in insufficient and uneven mixing. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide a waste gas incinerator for insulation board production, which solves the technical problem in the prior art where it is difficult to adjust the jet angle of the pipe when supplying gas through the incinerator, so as to achieve more sufficient contact with the waste gas in the incinerator.

[0006] According to one aspect, at least one embodiment of this disclosure provides a waste gas incinerator for insulation board production, including a furnace body mounted on a base plate, and further including a support frame, a side-blowing assembly, a top-blowing assembly, and an angle adjustment assembly. The support frame is fixedly mounted on the base plate. The side-blowing assembly is disposed on the side of the furnace body, and the top-blowing assembly is disposed on the top of the furnace body. The side-blowing assembly and the top-blowing assembly are connected by a gas supply assembly to synchronously supply gas to the top and side of the furnace body. Both the side-blowing assembly and the top-blowing assembly are provided with the angle adjustment assembly for adjusting the blowing angle. A drive assembly is disposed between the two angle adjustment assemblies for driving the two angle adjustment assemblies to adjust synchronously.

[0007] Furthermore, the side-blowing assembly includes an air inlet pipe, an air outlet pipe, and a U-shaped pipe. The air inlet pipe is installed through the support frame. Two air outlet pipes are rotatably connected between the side of the air inlet pipe and the side of the furnace body. The U-shaped pipe is disposed inside the furnace body. The other ends of the two air outlet pipes are connected to the U-shaped pipe, and the air outlet of the U-shaped pipe is connected to an air outlet hopper.

[0008] Furthermore, the top blowing assembly includes an air outlet pipe II, an air inlet pipe II, and a U-shaped pipe II. Two air outlet pipes II are rotatably connected to the top of the furnace body. The air inlet pipe II is connected to the top of the two air outlet pipes II. The U-shaped pipe II is disposed in the furnace body. The other end of the two air outlet pipes II is connected to the U-shaped pipe II, and the air outlet of the U-shaped pipe II is connected to the air outlet hopper.

[0009] Furthermore, the air supply assembly includes a blower, an air supply pipe, and a connecting pipe. The blower is installed on the side of the support frame, the air supply pipe is connected between the blower and the first air inlet pipe, and the connecting pipe is connected between the first air inlet pipe and the second air inlet pipe.

[0010] Furthermore, the angle adjustment assembly includes a first transmission wheel and a second transmission wheel. The first transmission wheel is fixedly installed on each of the two first air outlet pipes, and a transmission belt is tensioned and sleeved between the two first transmission wheels. The second transmission wheel is fixedly installed on each of the two second air outlet pipes, and a transmission belt is tensioned and sleeved between the two second transmission wheels.

[0011] Furthermore, the drive assembly includes a drive shaft, a support plate, a rotating shaft, a driving component, and a linkage component. The drive shaft is rotatably mounted on the side of the furnace body via a connecting plate. The support plate is fixedly mounted on the side of the furnace body, and a motor is mounted on the support plate. The output end of the motor is coaxially connected to the drive shaft. The rotating shaft is rotatably mounted through the side of the support plate. The driving component is disposed on the rotating shaft and the drive shaft, and the linkage component is disposed on the rotating shaft and the drive shaft.

[0012] Furthermore, the driving assembly includes a driving gear ring and a driving gear, the driving gear ring being fixedly mounted on the drive shaft, and the driving gear being fixedly mounted on one end of the rotating shaft.

[0013] Furthermore, the linkage component includes a first gear ring, a first gear, a second gear ring, and a second gear. The first gear ring is fixedly installed on one of the first air outlet pipes. The first gear is coaxially connected to the drive shaft and meshes with the first gear ring. The second gear ring is fixedly installed on one of the second air outlet pipes. The second gear is fixedly installed on the other end of the rotating shaft and meshes with the second gear ring.

[0014] In order to prevent the first U-shaped tube and the second U-shaped tube from contacting each other when rotating, the two second U-shaped tubes are further positioned above and to the sides of the two first U-shaped tubes.

[0015] To make the air entering the furnace more uniform, the two U-shaped tubes are placed perpendicular to the two U-shaped tubes.

[0016] The beneficial effects of the embodiments disclosed herein are as follows:

[0017] 1. In this disclosure, when air is introduced into the furnace body through the air supply component, the air can be simultaneously introduced from the top and side of the furnace body through the side blowing component and the top blowing component, respectively, so that the air entering the furnace body can come into more comprehensive contact with the exhaust gas in the furnace body, and the air can enter the furnace body through U-shaped pipe one and U-shaped pipe two to form two airflows, and be blown out through the air outlet duct.

[0018] 2. In this disclosure, during gas supply, the angle adjustment component can be driven by the drive component, thereby causing the two U-shaped tubes one and two U-shaped tubes two to rotate in the furnace body, thereby increasing the air flow area and increasing the air flow rate during rotation, so that the air can further contact the exhaust gas in the furnace body.

[0019] In summary, through the cooperation of the support frame, the side blowing assembly, the top blowing assembly, and the angle adjustment assembly, the incinerator can allow air to enter the furnace body from multiple directions, and can drive the air to rotate during the introduction, so that the air can fully contact the exhaust gas in the furnace body from multiple angles.

[0034] like Figures 1-6 As shown, this invention discloses an embodiment of a waste gas incinerator for insulating board production, including a furnace body 2 mounted on a base plate 1, a support frame 3, a side blowing assembly, a top blowing assembly, and an angle adjustment assembly. The support frame 3 is fixedly mounted on the base plate 1. The side blowing assembly is disposed on the side of the furnace body 2, and the top blowing assembly is disposed on the top of the furnace body 2. The side blowing assembly and the top blowing assembly are connected by a gas supply assembly to supply gas to the top and side of the furnace body 2 simultaneously. An angle adjustment assembly is provided on both the side blowing assembly and the top blowing assembly for adjusting the blowing angle. A drive assembly is provided between the two angle adjustment assemblies for driving the two angle adjustment assemblies to adjust synchronously.

[0035] like Figure 2 , Figure 3 and Figure 4When air is introduced into the furnace body 2, the air is first introduced into the furnace body 2 through the air supply assembly, the side blowing assembly, and the top blowing assembly. The air supply assembly includes a blower 11, an air supply pipe 12, and a connecting pipe 13. The blower 11 is installed on the side of the support frame 3. The air supply pipe 12 is connected between the blower 11 and the first air inlet pipe 4. The connecting pipe 13 is connected between the first air inlet pipe 4 and the second air inlet pipe 9. Specifically, when the blower 11 is started, the blower 11 introduces air into the side blowing assembly and the top blowing assembly through the air supply pipe 12 and the connecting pipe 13.

[0036] The side-blowing assembly includes an air inlet pipe 4, an air outlet pipe 5, and a U-shaped pipe 6. The air inlet pipe 4 is installed through the support frame 3. Two air outlet pipes 5 are rotatably connected between the side of the air inlet pipe 4 and the side of the furnace body 2. The U-shaped pipe 6 is located inside the furnace body 2. The other end of each of the two air outlet pipes 5 is connected to the U-shaped pipe 6, and the air outlet of the U-shaped pipe 6 is connected to the air outlet 7. The top-blowing assembly includes an air outlet pipe 8, an air inlet pipe 9, and a U-shaped pipe 10. Two air outlet pipes 8 are rotatably connected to the top of the furnace body 2. The air inlet pipe 9 is connected to the top of the two air outlet pipes 8. The U-shaped pipe 10 is located inside the furnace body 2. The other end of each of the two air outlet pipes 8 is connected to the U-shaped pipe 10, and the air outlet of the U-shaped pipe 10 is connected to the air outlet 7.

[0037] Specifically, the air supply pipe 12 introduces air into the inlet pipe 4 and then into the inlet pipe 9 through the connecting pipe 13. The air in the inlet pipe 4 enters the U-shaped pipe 6 through the outlet pipe 5 and is ejected through the outlet 7 of the U-shaped pipe 6. The air in the inlet pipe 9 enters the U-shaped pipe 10 through the two outlet pipes 8 and is ejected through the outlet 7 of the U-shaped pipe 10. The air enters the furnace body 2 simultaneously through the top and side ends, thus mixing with the air in the furnace body 2. Because the two U-shaped pipes 16 are placed perpendicular to the two U-shaped pipes 10 respectively, and the U-shaped design of the U-shaped pipes 16 and 10 allows the air to be ejected in two streams, thus making the contact between the air and the exhaust gas more uniform.

[0038] like Figure 5As shown, after air is introduced, the angles of U-tube 1 6 and U-tube 2 10 can be adjusted by the cooperation of the angle adjustment component and the drive component, thereby changing the angle of the injected air. The angle adjustment component includes a transmission wheel 14 and a transmission wheel 2 16. Transmission wheels 14 are fixedly installed on both air outlet pipes 1 5, and a transmission belt 15 is tensioned between the two transmission wheels 14. Transmission wheels 2 16 are fixedly installed on both air outlet pipes 2 8, and a transmission belt 15 is tensioned between the two transmission wheels 2 16. The drive component includes a drive shaft 17, a support plate 18, a rotating shaft 19, a drive component, and a linkage component. The drive shaft 17 is rotatably mounted on the side of the furnace body 2 through a connecting plate. The support plate 18 is fixedly mounted on the side of the furnace body 2, and a motor 26 is mounted on the support plate 18. The output end of the motor 26 is coaxially connected to the drive shaft 17. A rotating shaft 19 is rotatably mounted on the side of a support plate 18. A drive assembly is mounted on the rotating shaft 19 and a drive shaft 17. A linkage assembly is mounted on the rotating shaft 19 and the drive shaft 17. The drive assembly includes a drive gear ring 20 and a drive gear 21. The drive gear ring 20 is fixedly mounted on the drive shaft 17, and the drive gear 21 is fixedly mounted on one end of the rotating shaft 19. The linkage assembly includes a first gear ring 22, a first gear 23, a second gear ring 24, and a second gear 25. The first gear ring 22 is fixedly mounted on one of the air outlet pipes 5. The first gear 23 is coaxially connected to the drive shaft 17 and meshes with the first gear ring 22. The second gear ring 24 is fixedly mounted on one of the air outlet pipes 8, and the second gear 25 is fixedly mounted on the other end of the rotating shaft 19 and meshes with the second gear 25.

[0039] Specifically, starting the motor 26 causes the output of the motor 26 to drive the drive shaft 17 to rotate. The drive shaft 17 drives the gear ring 20 to rotate, which in turn drives the gear 21 meshing with it to rotate. Simultaneously, the drive shaft 17 drives the first gear 23 to rotate. The first gear 23 and the gear 21 respectively drive the first gear ring 22 and the rotating shaft 19 to rotate. The first gear ring 22 drives one of the air outlet pipes 5 to rotate. Then, the rotating shaft 19 drives the second gear 25 to rotate. The second gear 25 drives another air outlet pipe 5 to rotate. When the second air duct 8 rotates, one of the air outlet ducts 1 and 2 respectively drives one of the transmission wheels 14 and 2 to rotate. Under the tensioning effect of the transmission belt 15, the other air outlet duct 1 and 2 rotate. The air outlet duct 1 and 2 drive the U-shaped tube 6 and U-shaped tube 2 to rotate inside the furnace body 2, thereby allowing the air to come into further contact with the exhaust gas inside the furnace body 2. And because the two U-shaped tubes 2 are located on the sides and above the two U-shaped tubes 6 respectively, the U-shaped tubes 1 and 2 will not touch each other during rotation.

[0040] Working Principle: When incinerating waste gas, the waste gas is first introduced into the incinerator, and simultaneously blower 11 is started. Blower 11 introduces air through air supply pipe 12 into inlet pipe 4, and then through connecting pipe 13 into inlet pipe 9. The air in inlet pipe 4 enters U-shaped pipe 6 through outlet pipe 5, and is ejected through outlet hopper 7 of U-shaped pipe 6. The air in inlet pipe 9 enters U-shaped pipe 10 through two outlet pipes 8, and is ejected through outlet hopper 7 of U-shaped pipe 10. Air enters the furnace body 2 simultaneously through the top and side ends. At the same time, motor 26 is started. The output end of motor 26 drives drive shaft 17 to rotate, drive shaft 17 drives gear ring 20 to rotate, and drives gear ring 20 to drive the belt meshing with it. The rotating gear 21 drives the drive shaft 17 to drive the first gear 23 to rotate. The first gear 23 and the drive gear 21 drive the first gear ring 22 and the rotating shaft 19 to rotate respectively. The first gear ring 22 drives one of the air outlet pipes 5 to rotate. Then the rotating shaft 19 drives the second gear 25 to rotate. The second gear 25 drives the second gear 25 to rotate. The second gear 25 drives one of the air outlet pipes 8 to rotate. One of the air outlet pipes 5 and the second air outlet pipe 8 drive one of the transmission wheels 14 and the second transmission wheel 16 to rotate respectively. Under the action of the tensioning sleeve of the transmission belt 15, the other air outlet pipe 5 and the second air outlet pipe 8 are driven to rotate. The air outlet pipe 5 and the second air outlet pipe 8 drive the U-shaped pipe 6 and the second U-shaped pipe 10 to rotate in the furnace body 2, so that the air and the exhaust gas in the furnace body 2 are further contacted.

[0041] like Figure 6 As shown, the exhaust gas enters the combustion chamber and, under the high temperature generated by the combustion of auxiliary materials, mixes thoroughly with oxygen and undergoes an oxidation reaction. Organic pollutants react with oxygen to form carbon dioxide and water, and toxic and harmful components are completely decomposed, losing their toxicity and odor. Pollutants containing nitrogen, sulfur, and other elements may be converted into nitrogen oxides, sulfur dioxide, etc., which can be further treated by denitrification and desulfurization devices.

[0042] It should be added that multiple protective covers can be detachably installed on the furnace body 2, and the driving gear ring 20, driving gear 21, first gear ring 22, first gear 23, second gear ring 24 and second gear 25 are located inside the protective covers, so that the protective covers protect their meshing. In addition, U-shaped tube 1 6, U-shaped tube 2 10 and air outlet 7 are all made of high temperature resistant material.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
