Description

Technical Field

[0001] This invention relates to the field of incineration technology, specifically to an oxygen-enriched incinerator for high-altitude domestic waste that utilizes multi-stage air distribution from an oxygen-generating device. Background Technology

[0002] Waste incineration is the mainstream technology for municipal solid waste treatment, but its application in high-altitude areas faces severe challenges. The thin air at high altitudes, with atmospheric oxygen content only 60%-70% of that at sea level, leads to incomplete combustion, low thermal efficiency, and the generation of large amounts of harmful pollutants such as dioxins, CO, and unburned particulate matter. This not only reduces waste reduction but also exacerbates environmental and health risks. For example, in existing technologies, traditional waste incinerators operating at high altitudes often rely on a single air supply system, which lacks sufficient control over wind speed and oxygen concentration, making it unable to adapt to the complex changes in waste composition. This results in problems such as fluctuating furnace temperature, coking, and excessive emissions. Summary of the Invention

[0003] The purpose of this invention is to provide an oxygen-enriched incinerator for municipal solid waste in high-altitude areas that utilizes a multi-stage air distribution system for oxygen generation equipment. This solves the problems of traditional waste incinerators, which often rely on a single air supply system when operating in high-altitude areas. The system suffers from insufficient control over wind speed and oxygen concentration, making it unable to adapt to the complex changes in waste composition, which in turn leads to furnace temperature fluctuations, coking, and excessive emissions.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An oxygen-enriched incinerator for high-altitude municipal solid waste, utilizing multi-stage air distribution from an oxygen generator, includes an incinerator body and an air supply unit.

An inclined combustion grate is installed within the combustion chamber. A feed inlet is located at the height of the combustion grate on the incinerator body. A drying section is located at the feed inlet on the incinerator body. A drying air duct is located near the top of the combustion chamber, with one end of the drying air duct placed inside the drying section and the other end outside the incinerator body. A first fan is connected to the gas supply section, and a mixing chamber is provided inside the gas supply section. An oxygen generating device for supplying oxygen to the mixing chamber is provided inside the mixing chamber. An air inlet pipe is provided inside the mixing chamber.

A second gas supply pipe is provided above the combustion grate in the combustion chamber. The air inlet end of the second gas supply pipe is placed inside the mixing chamber and is connected to a fourth fan.

[0006] A further technical solution is that a number of first gas outlet short pipes with downward openings are provided on the lower side of the first gas supply pipe, the second gas supply pipe is arranged around the inner wall of the combustion chamber, the second gas supply pipe is connected to the fourth blower through the first connecting pipe, and a number of second gas outlet short pipes connected to the second gas supply pipe are provided on the inner wall of the second gas supply pipe, with the gas outlets of the second gas outlet short pipes facing downwards.

[0007] A further technical solution involves a first rotating tube vertically arranged inside the mixing chamber, with the outlet of the oxygen generator facing upwards and rotatably connected to the lower end of the first rotating tube via a first rotating connecting block. A first motor is installed at the top of the mixing chamber, and the output shaft of the first motor is connected to the upper end of the first rotating tube. Several first air holes penetrating the inside and outside are provided on the outer wall of the first rotating tube. A second rotating tube is vertically arranged inside the mixing chamber, with a second connecting tube at the top of the mixing chamber. The lower end of the second connecting tube is rotatably connected to the upper end of the second rotating tube via a second rotating connecting block. An air inlet pipe is connected to the second connecting tube. A second motor is installed on the upper side of the oxygen generator, and the output shaft of the second motor is connected to the lower end of the second rotating tube. Several second air holes penetrating the inside and outside are provided on the outer wall of the second rotating tube.

[0008] A further technical solution is that a rotating groove is provided on the upper side of the first rotating connecting block, the lower end of the first rotating tube is placed in the rotating groove, and is rotatably connected to the groove wall of the rotating groove through a rotating bearing. The groove opening of the rotating groove is sealed and fitted to the outer wall of the first rotating tube through a sealing ring, and the bottom of the rotating groove is connected to the gas outlet of the oxygen generating equipment through a connecting hole.

[0009] A further technical solution is to have multiple mesh panels on the upper side of the combustion grate, with the middle of the mesh panels protruding towards the high side of the combustion grate.

[0010] A further technical solution is that the drying section includes a drying drum, a support frame, a movable rod, and a fixed rod. The fixed rod is connected to the incinerator body at the feed inlet. The upper side of one end of the movable rod is rotatably connected to the upper side of the fixed rod end via a hinge. The support frame is fixedly connected to the incinerator body below the fixed rod. An electric telescopic rod is vertically installed on the lower side of the support frame away from the incinerator body. The telescopic end of the electric telescopic rod abuts against the lower side of the movable rod. Two arc-shaped guide rails are provided on the upper side of the movable rod.

[0013] Compared with existing technologies, the beneficial effects of this invention are: 1. By setting up a drying duct and a drying section, the waste can be thoroughly dried and preheated before entering the incineration chamber. This avoids incomplete combustion caused by excessive water vapor during incineration, which would affect the combustion effect within the incineration chamber. The drying duct uses the heat within the incineration chamber to heat the air flowing through it, thereby drying the waste in the drying section with high-temperature air. 2. By setting up an air supply section, the oxygen content in the air can be increased using an oxygen generator. This solves the problem of thin air and low oxygen content in high-altitude areas. Furthermore, the air entering the mixing chamber is heated by the air inlet duct, thereby increasing the temperature of the gas entering the incineration chamber and preventing low-temperature air from affecting the combustion effect. 3. By setting up a first air supply pipe and a second air supply pipe, oxygen can be supplied to the burning waste on both sides of the combustion grate, which can greatly improve the combustion effect. The first, third, and fourth fans enable multi-stage air distribution before and during combustion, improving combustion efficiency and combustion effect. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] Figures 1 to 6 The image shows an embodiment of the present invention.

[0023] Example 1:

[0024] An oxygen-enriched incinerator for high-altitude municipal solid waste, utilizing multi-stage air distribution from an oxygen generator, includes an incinerator body 1 and an air supply unit 2. The incinerator body 1 contains a combustion chamber 3. A flue gas pipe 4, connected vertically to the top of a mixing chamber 9, is installed and communicates with the combustion chamber 3. A combustion grate 5 is inclinedly arranged within the combustion chamber 3. An inlet 6 is located at the height of the combustion grate 5 on the incinerator body 1. A drying section is located at the inlet 6 on the incinerator body 1. A drying air duct 7 is located near the top of the combustion chamber 3. One end of the drying air duct 7 is placed inside the drying section, and the other end is connected to a first blower 8 on the outside of the incinerator body 1. The gas supply section 2 is equipped with a mixing chamber 9, and an oxygen generating device 10 for supplying oxygen to the mixing chamber 9 is installed in the mixing chamber 9. An air inlet pipe 11 is installed in the mixing chamber 9. The end of the mixing chamber 9 away from the mixing chamber 9 passes through the combustion chamber 3 and the exhaust pipe 4 in sequence and is connected to a second fan 12. The combustion chamber 3 is equipped with a first gas supply pipe 13 below the combustion grate 5. The air inlet end of the first gas supply pipe 13 is placed in the mixing chamber 9 and is connected to a third fan 14. The combustion chamber 3 is equipped with a second gas supply pipe 15 above the combustion grate 5. The air inlet end of the second gas supply pipe 15 is placed in the mixing chamber 9 and is connected to a fourth fan 16. By setting up a drying duct 7 and a drying section, the waste can be thoroughly dried and preheated before entering the incineration chamber 3. This avoids incomplete combustion caused by excessive moisture during incineration, which would affect the combustion effect within the incineration chamber 3. The drying duct 7 uses the heat from the incineration chamber 3 to heat the air flowing through it, thereby drying the waste in the drying section with high-temperature air. By setting up an air supply section 2, the oxygen content in the air can be increased using an oxygen generator 10, thus solving the problem of thin air and low oxygen content in high-altitude areas. Furthermore, the air entering the mixing chamber 9 is heated by the air inlet duct 11, thereby increasing the temperature of the gas entering the incineration chamber 3 and preventing low-temperature air from affecting the combustion effect. By setting up a first air supply pipe 13 and a second air supply pipe 15, oxygen can be supplied to the burning waste on both sides of the combustion grate 5, which can greatly improve the combustion effect. By using a first fan 8, a third fan 14, and a fourth fan 16, multi-stage air distribution can be achieved before and during combustion, improving combustion efficiency and combustion effect.

[0025] The lower side of the first air supply pipe 13 is provided with several downward-facing first air outlet short pipes 17. The second air supply pipe 15 is arranged around the inner wall of the incineration chamber 3. The second air supply pipe 15 is connected to the fourth blower 16 through the first connecting pipe 18. The inner wall of the second air supply pipe 15 is provided with several second air outlet short pipes 19 connected to the second air supply pipe 15, and the air outlets of the second air outlet short pipes 19 are arranged downward. By setting the first air outlet short pipes 17, the direction of air supply can be controlled to prevent ash and slag from falling into the first air outlet short pipes 17 and blocking them. By setting the second air outlet short pipes 19, the blockage of the second air outlet short pipes 19 can be prevented when garbage enters the incineration chamber 3. With the help of the structure of the second air supply pipe 15, air can be evenly supplied around the incineration chamber 3, and air can be blown from above the combustion position to aid combustion.

[0026] A first rotating tube 20 is vertically arranged inside the mixing chamber 9. The outlet end of the oxygen generating device 10 is rotatably connected to the lower end of the first rotating tube 20 through a first rotating connecting block 21. A first motor 22 is arranged at the top of the mixing chamber 9. The output shaft of the first motor 22 is connected to the upper end of the first rotating tube 20. Several first air holes 23 penetrating the inside and outside are arranged on the outer wall of the first rotating tube 20. A second rotating tube 24 is vertically arranged inside the mixing chamber 9. A second connecting tube 25 is arranged at the top of the mixing chamber 9. The lower end of the second connecting tube 25 is rotatably connected to the upper end of the second rotating tube 24 through a second rotating connecting block 26. The air inlet pipe 11 is connected to the second connecting tube 25. A second motor 27 is installed on the upper side of the oxygen generating device 10. The output shaft of the second motor 27 is connected to the lower end of the second rotating tube 24. Several second air holes 28 penetrating the inside and outside are arranged on the outer wall of the second rotating tube 24. Through the first rotating pipe 20 and the second rotating pipe 24, oxygen and air can be supplied to the mixing chamber 9 during the rotation driven by the first motor 22 and the second motor 27, so that the oxygen and air can be quickly and evenly mixed in the mixing chamber 9, thereby increasing the overall oxygen content. In this way, when the third fan 14 and the fourth fan 16 supply air to the combustion chamber 3, uniform oxygen-rich air can be provided.

[0027] A rotating groove 29 is provided on the upper side of the first rotating connecting block 21. The lower end of the first rotating tube 20 is placed in the rotating groove 29 and is rotatably connected to the groove wall of the rotating groove 29 through a rotating bearing 30. The groove opening of the rotating groove 29 is sealed to the outer wall of the first rotating tube 20 through a sealing ring 31. The bottom of the rotating groove 29 is connected to the outlet of the oxygen generator 10 through a connecting hole 32. With the help of the rotating groove 29 and the rotating bearing 30, the first rotating tube 20 can rotate smoothly in the rotating groove 29 under the drive of the first motor 22. By setting the sealing ring 31, a large amount of oxygen can be prevented from leaking from the connection between the rotating ring groove and the first rotating tube 20. The sealing ring 31 is made of rubber or other flexible sealing material.

[0028] Multiple mesh panels 33 are provided on the upper side of the combustion grate 5, with the center of each mesh panel 33 protruding towards the higher side of the combustion grate 5. By providing multiple mesh panels 33, after the waste is poured into the incineration chamber 3, multiple cavities are formed in the waste pile with the help of the mesh panels 33. This helps to increase the combustion area and improve the gas supply effect, thereby enhancing the combustion efficiency.

[0029] The drying section includes a drying drum 34, a support frame 35, a movable rod 36, and a fixed rod 37. The fixed rod 37 is connected to the incinerator body 1 at the feed inlet 6. The upper side of one end of the movable rod 36 is rotatably connected to the upper side of the fixed rod 37 via a hinge 38. The support frame 35 is fixedly connected to the incinerator body 1 below the fixed rod 37. An electric telescopic rod 39 is vertically installed on the lower side of the support frame 35 away from the incinerator body 1. The telescopic end of the electric telescopic rod 39 abuts against the lower side of the movable rod 36. Two arc-shaped guide rails 40 are provided on the upper side of the movable rod 36, surrounding the drying drum. The outer wall of the rotating drum 34 is provided with a slide rail 41 that is slidably connected to two arc-shaped guide rails 40. A toothed ring 42 is provided around the outer wall of the drying rotating drum 34. A drive motor 43 is installed on the movable rod 36. A gear 44 that meshes with the toothed ring 42 is installed on the output shaft of the drive motor 43. A spiral stirring blade 45 is provided around the inner wall of the drying rotating drum 34. A shielding ring plate 46 is provided at the end of the drying rotating drum 34 away from the incinerator body 1. A removable sealing plate is provided at the center hole of the shielding ring plate 46. A feed hopper 47 is provided at the feed inlet 6 of the incinerator body 1. Before the waste is poured into the incineration chamber 3, it is manually or by a hoisted machine poured into the drying drum 34. A sealing plate is then installed on the baffle ring 46, blocking the central hole of the baffle ring 46. The drying drum 34 is rotated by the drive motor 43, and the spiral stirring blades 45 prevent the waste from falling out during the drying process. High-temperature air is then supplied to the drying drum 34 through the drying air duct 7. This air, combined with the agitated waste, effectively blows the moisture out of the waste, achieving the desired drying effect. After drying is complete, the end of the electric telescopic rod 39 or electric movable rod 36 away from the rotating hinge 38 tilts, causing the drying drum to tilt. The drive motor 43 then rotates the drying drum 34 in the opposite direction, using the stirring blades 45 to discharge the waste from the drying drum. The discharged waste falls into the incineration chamber 3 through the feed hopper 47 and feed inlet 6 for incineration.

[0030] A heating water tank 48 is installed on the upper side of the incinerator body 1, and several first baffles are installed inside the drying air duct 7, while several second baffles are installed inside the air inlet pipe. The heating water tank 48 absorbs the heat generated during waste combustion to heat the water, thus achieving heat energy recovery. The first and second baffles allow air to collide multiple times with the pipe walls as it enters the drying air duct 7 and the air inlet pipe, improving heat exchange efficiency.

[0031] The drying duct 7 is located inside the drying drum 34. One end of the duct has an air outlet 49, and several third air holes 50 connected to the drying duct 7 are arranged around the edge of the air outlet 49. With the help of the air outlet 49 and the third air holes 50, air can enter the drying drum 34 and impact the garbage at an angle, thereby drying the garbage.

[0032] Although the invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
