Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, specifically to a waste treatment device that uses high-efficiency combustion to render waste harmless. Background Technology

[0002] With the rapid development of modern life, the amount of household waste generated is gradually increasing, especially urban household waste. There are many ways to deal with household waste. For non-combustible and biodegradable waste, landfill is generally used, while for combustible waste, incineration is generally used. However, the incineration process will burn the land, and the smoke and harmful gases produced by incineration will have a harmful impact on the environment. Therefore, there is a need for a harmless treatment device for waste that uses efficient incineration.

[0003] In existing technologies, waste treatment devices that use high-efficiency combustion generally employ flamethrowers to directly burn the waste. However, it is difficult for piled-up waste to burn completely, and the combustion efficiency is low for the inner layers of waste.

[0004] Therefore, the present invention provides a harmless treatment device for waste by high-efficiency combustion. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a harmless treatment device for waste by high-efficiency combustion to solve the above problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a harmless treatment device for high-efficiency combustion of waste, comprising a combustion chamber, an inlet opening on one side outer wall of the combustion chamber, a flue gas outlet opening on the top outer wall of the combustion chamber, a gas device body being provided on the flue gas outlet, a turning mechanism being provided inside the combustion chamber, and a cleaning mechanism being provided above the turning mechanism.

[0007] The flipping mechanism includes a rotating motor, the output shaft of which is fixedly connected to a rotating shaft, and several flipping plates are fixedly connected to both sides of the rotating shaft. The flipping plates are made of a high-temperature resistant material.

[0008] Preferably, rotating plates are fixedly connected to both sides below the rotating shaft, and the rotating plates are perpendicular to the flipping plate.

[0009] Preferably, an air intake pump is fixedly connected to one side of the outer wall of the combustion chamber, and the exhaust end of the air intake pump extends into the combustion chamber.

[0010] Preferably, the combustion chamber is provided with an air supply ring surrounding the rotating shaft. The outer wall of the air supply ring is opened at the air inlet. The inner wall of the air inlet is connected to and fixed to the exhaust end of the air pump. The inner wall of the air supply ring is opened at a number of evenly distributed air supply ports.

[0011] Preferably, both exhaust ports on both sides of the gas device body are fixedly connected to gas supply pipes, which extend to the bottom of the combustion chamber.

[0012] Preferably, a smoke conveying pipe is fixedly connected to the inner wall of the exhaust port, the smoke conveying pipe is fixed to the smoke inlet end of the gas device body, and a filter screen plate is fixedly connected to the inner wall of the smoke conveying pipe, the filter screen plate having a double-layer structure.

[0013] Preferably, a cleaning screen is fixedly connected to the top of the rotating shaft, and a gap is left between the cleaning screen and the bottom outer wall of the filter screen.

[0014] Preferably, cleaning rods are fixedly connected to both sides of the top inner wall of the combustion chamber. The cleaning rods are L-shaped and contact the bottom of the impurity removal mesh plate.

[0015] Beneficial effects

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] (1) The waste is treated by a high-efficiency combustion harmless treatment device. The waste can be put into the combustion box through the feed port. The waste is ignited by a flamethrower installed on one side in the combustion box. The rotating motor is started. The output shaft of the rotating motor rotates, which causes the rotating shaft to rotate. The rotation of the rotating shaft causes the flipping plate to rotate. The rotation of the flipping plate and the rotating plate can turn the waste. Since the two are perpendicular, the pushing position of the two under the same cross section helps the waste that has been burned into ash to move down or turn quickly. The waste can be turned, and the effect of more complete combustion of waste can be achieved.

[0018] (2) The waste is treated by a high-efficiency combustion harmless treatment device. The rotation of the impurity removal screen plate can form a relative rotation with the filter screen plate, which can remove the residual solid waste between the two through friction. This can prevent the bottom of the filter screen plate from being blocked. At the same time, since the gap between the two is small, the flue gas can enter the filter screen plate through the surface of the impurity removal screen plate, which can share the filtration operation of the filter screen plate and extend the service life of the filter screen plate. In addition, the rotation operation of the impurity removal screen plate can make the cleaning rod scrape its bottom and sides, which can perform a certain cleaning operation on the impurity removal screen plate.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-4 A harmless waste treatment device for high-efficiency combustion includes a combustion chamber 1, a feed inlet 2 is opened on one side outer wall of the combustion chamber 1, a smoke outlet 18 is opened on the top outer wall of the combustion chamber 1, a gas device body 3 is provided on the smoke outlet 18, a turning mechanism is provided inside the combustion chamber 1, and a cleaning mechanism is provided above the turning mechanism.

[0026] The flipping mechanism includes a rotating motor 4, the output shaft of the rotating motor 4 is fixedly connected to a rotating shaft 5, and several flipping plates 6 are fixedly connected to both sides of the rotating shaft 5. The flipping plates 6 are made of high temperature resistant material, and rotating plates 7 are fixedly connected to both sides below the rotating shaft 5. The rotating plates 7 are perpendicular to the flipping plates 6.

[0027] Specifically, waste can be fed into the combustion chamber 1 through the feed inlet 2. Inside the combustion chamber 1, a flamethrower installed on one side is used to ignite the waste. The rotating motor 4 is started, and the output shaft of the rotating motor 4 rotates, which causes the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 causes the flipping plate 6 and the rotating plate 7 to rotate. The rotation of the flipping plate 6 and the rotating plate 7 can turn the waste. Since the two are perpendicular, their pushing positions under the same cross section help the waste that has been burned into ash to move down or turn over quickly, thus turning the waste and achieving a more complete combustion effect.

[0028] As a further improvement of the present invention, an air intake pump 8 is fixedly connected to one side of the outer wall of the combustion chamber 1. The exhaust end of the air intake pump 8 extends into the combustion chamber 1. An air supply ring 9 surrounding the rotating shaft 5 is provided inside the combustion chamber 1. The outer wall of the outer ring of the air supply ring 9 is opened at the air inlet 10. The inner wall of the air inlet 10 is connected to and fixed to the exhaust end of the air intake pump 8. The inner wall of the inner ring of the air supply ring 9 is opened at several evenly distributed air supply ports 11. Air supply pipes 16 are fixedly connected to the exhaust ports on both sides of the gas device body 3. The air supply pipes 16 extend to the bottom of the combustion chamber 1.

[0029] Specifically, by starting the air intake pump 8, the air intake pump 8 can inject air into the air supply ring 9 through the air intake port 10. Combustion-supporting gas can be added. As the gas enters the combustion chamber 1 through the air supply port 11, it can increase the combustion range of the flame and further improve the combustion rate of the waste. At the same time, the gas can blow the waste in the combustion chamber 1, which can make the waste burn more completely. After the gas device body 3 treats the flue gas, the high-temperature harmless flue gas can be blown to the bottom of the combustion chamber 1 through the air supply pipe 16, which can heat up the bottom of the combustion chamber 1. This helps the liquid waste remaining on the inner wall of the bottom of the combustion chamber 1 to dry, which can reduce the interference of liquid waste on the combustion of the waste.

[0030] As a further improvement of the present invention, a smoke conveying pipe 13 is fixedly connected to the inner wall of the smoke outlet 18. The smoke conveying pipe 13 is fixed to the smoke inlet end of the gas device body 3. A filter screen plate 12 is fixedly connected to the inner wall of the smoke conveying pipe 13. The filter screen plate 12 has a double-layer structure. A dirt removal screen plate 14 is fixedly connected to the top of the rotating shaft 5. A gap is left between the dirt removal screen plate 14 and the bottom outer wall of the filter screen plate 12.

[0031] Specifically, the rotation of the rotating shaft 5 allows the impurity removal screen 14 to rotate, and the rotation of the impurity removal screen 14 can form a relative rotation with the filter screen 12, which can remove residual solid waste between the two through friction, thus preventing the bottom of the filter screen 12 from becoming blocked. At the same time, since the gap between the two is small, the flue gas can enter the filter screen 12 through the surface of the impurity removal screen 14, which can share the filtration operation of the filter screen 12 and extend the service life of the filter screen 12.

[0032] As a further improvement of the present invention, cleaning rods 15 are fixedly connected to both sides of the top inner wall of the combustion chamber 1. The cleaning rods 15 are L-shaped and are in contact with the bottom of the impurity removal mesh plate 14.

[0033] Specifically, by rotating the impurity removal screen 14, the cleaning rod 15 can scrape its bottom and sides, thus cleaning the impurity removal screen 14.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] Working principle of the invention: In use, garbage can be put into the combustion chamber 1 through the feed port 2. Inside the combustion chamber 1, the garbage is ignited using a flamethrower installed on one side. The rotating motor 4 is started, and the output shaft of the rotating motor 4 rotates, which causes the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 causes the flipping plate 6 and the rotating plate 7 to rotate. The rotation of the flipping plate 6 and the rotating plate 7 can turn the garbage. Since the two are perpendicular, their pushing positions under the same cross section help the garbage burned to ash to move down or turn quickly, thus turning the garbage and achieving a more complete combustion effect.

[0036] As the waste burns, the air pump 8 can be started. The air pump 8 can inject air into the air supply ring 9 through the air inlet 10. Combustion-supporting gas can be added. As the gas enters the combustion chamber 1 through the air supply port 11, the combustion range of the flame can be increased, which can further improve the combustion rate of the waste. At the same time, the gas can blow the waste in the combustion chamber 1, which can make the waste burn more completely.

[0037] As the waste is burned, a large amount of flue gas is generated. After the flue gas is treated by the gas device body 3, the high-temperature harmless flue gas can be blown to the outside of the combustion chamber 1 through the gas pipe 16. This can heat up the bottom of the combustion chamber 1, which helps the liquid waste remaining in the inner wall of the bottom of the combustion chamber 1 to dry up and reduce the interference of liquid waste on the combustion of waste.

[0038] As the rotating shaft 5 rotates, the impurity removal screen 14 rotates, creating a relative rotation with the filter screen 12. This friction removes residual solid waste between the two screens, preventing the bottom of the filter screen 12 from becoming clogged. Furthermore, due to the small gap between them, flue gas can pass through the surface of the impurity removal screen 14 into the filter screen 12, thus sharing the filtration workload and extending the service life of the filter screen 12. Additionally, the rotation of the impurity removal screen 14 allows the cleaning rod 15 to scrape its bottom and sides, performing a cleaning operation.

[0039] The gas device body 3 in this application can be constructed by sequentially connecting high-temperature coarse dust removal, high-temperature denitrification, and high-temperature fine dust removal + adsorbent injection to form a high-temperature flue gas purification system with no or slight temperature drop throughout the process. This system perfectly matches the high-temperature environment of waste incineration. The core combination consists of a ceramic multi-tube cyclone dust collector (1000℃), an SNCR denitrification device (850-1100℃), a high-temperature ceramic filter tube dust collector (600-800℃), and a high-temperature adsorbent injection device. The flue gas temperature drop throughout the process is <100℃ (all natural heat dissipation, no active cooling), which can fully heat the combustion chamber. Further details are omitted here.
