Description

Technical Field

[0001] The invention belongs to the technical field of waste incineration equipment, and in particular relates to a high-efficiency incinerator. Background Art

[0002] Small-scale domestic waste incinerators are necessary waste treatment equipment for industry, daily life and remote areas. There is currently no traditional production standard for small-scale domestic waste incinerators. Most existing manufacturers use fuel oil for incineration. This incineration method generates smoke emissions into the air when the combustion is incomplete, which can cause environmental pollution.

[0003] Small-scale domestic waste incinerators often use intermittent incineration when burning garbage, that is, after completing the loading of garbage once, the feed port is closed for incineration, and garbage is loaded again after the incineration is completed. The smoke exhaust port of existing small-scale domestic waste incinerators is usually set above the furnace, which will cause the garbage accumulated above the furnace in the case of wet garbage such as weeds, fallen leaves, and kitchen waste to affect the rise of smoke generated by the burning of garbage below, which will not only lead to incomplete combustion of garbage, but also dead corners of combustion, and fail to achieve the 3T+E combustion index ("3T+E" refers to the comprehensive application of temperature, time, turbulence, and energy). Even because the flue gas stays in the furnace for a long time, the pressure in the furnace increases, causing part of the flue gas to be discharged from the ash discharge port and inspection port, causing environmental pollution.

[0004] Therefore, it is necessary to study an efficient incinerator with no dead corners in the furnace, full combustion, long residence time of flue gas in the furnace, and smooth discharge through the exhaust pipe. Summary of the invention

[0038] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0039] See also Figures 1 to 10 As shown, a high-efficiency incinerator comprises: a frame 1 for supporting, a circular furnace 2 for incinerating garbage, a feeding mechanism 4 for filling the circular furnace 2 with garbage, and an oxygen supply device 5 for aerating the circular furnace 2.

[0040] The frame 1 is provided with an ash discharge mechanism 12 and a first smoke pipe 13. The ash discharge mechanism 12 is provided at the bottom of the frame 1. It should be noted that the ash discharge mechanism 12 can store part of the ash generated by incineration, and at the same time, the valve below can be opened to discharge the ash from the incinerator. Specifically, the frame 1 is provided with an inspection port 11, and the inspection port 11 is connected to the circular furnace 2.

[0041] The circular furnace 2 is provided with a grate 21, a dust reduction mechanism 23 and a smoke collection mechanism 3. Preferably, the circular furnace 2 is cast and molded with a high-strength, shock-resistant and corrosion-resistant corundum mullite refractory material to prevent the loosening of the refractory brick furnace used in the incinerator during transportation, causing the combustion smoke to be exposed. The grate 21 is fixedly arranged at the bottom of the circular furnace 2. It can be understood that the ash produced after the incineration of garbage can fall into the ash discharge mechanism 12 through the grate 21. The smoke collection mechanism 3 is fixedly arranged on the side wall of the circular furnace 2. It should be noted that the circular furnace 2 is a vertical circular structure. The purpose of adopting this structure is to allow high-temperature smoke and oxygen to be more fully mixed and burned through the turbulent wind during the aeration of the oxygen supply device 5, which can effectively ensure that there is no dead corner smoke escape problem in the furnace and the combustion is more complete.

[0042] The smoke collecting mechanism 3 includes a plurality of smoke inlet components 31, a smoke collecting ring pipe 32 and a plurality of ash discharge components 33. The plurality of smoke inlet components 31 are evenly arranged on the upper end surface of the smoke collecting ring pipe 32 along the circumference. Specifically, the smoke inlet component 31 is provided with a first flap 311, a first limit block 312 and a second limit block 313. The lower end of the first flap 311 is hinged on the smoke inlet component 31, and the first flap 311 is connected to the smoke inlet component 31 through a torsion spring. It can be understood that when there is no external force pushing, the torsion spring will push the upper end of the first flap 311 to flip toward the circular furnace 2. The first stop block 312 and the second stop block 313 are fixedly connected to the upper end of the smoke inlet assembly 31. The first stop block 312 cooperates with the side of the first flap 311 close to the circular furnace 2, and the second stop block 313 cooperates with the other side of the first flap 311, that is, the first stop block 312 can limit the angle at which the first flap 311 flips toward the circular furnace 2. At the same time, the first flap 311 cooperates with the first stop block 312 to prevent garbage from entering the smoke inlet assembly 31. When burning garbage, under the action of pressure, the first flap 311 flips in the direction away from the circular furnace 2, and the smoke generated by the burning can enter the smoke collecting ring duct 32 through the smoke inlet assembly 31. The second stop block 313 can limit the flip angle of the first flap 311 to prevent garbage from entering the smoke collecting ring duct 32 through the smoke inlet assembly 31 together with the smoke. Part of the ash generated by the combustion can enter the smoke collecting ring duct 32 with the smoke, and sewage in the wet garbage can also enter the smoke collecting ring duct 32.

[0043] The multiple ash discharge components 33 are evenly arranged along the circumference on the lower end surface of the smoke collecting ring tube 32. Specifically, the ash discharge component 33 is provided with a second flap 331 and a third limit block 332. The upper end of the second flap 331 is hinged to the ash discharge component 33, and the second flap 331 is connected to the ash discharge component 33 through a torsion spring. It can be understood that the torsion spring can drive the lower end of the second flap 331 to flip toward the side away from the circular furnace 2. The third limit block 332 is fixedly arranged at the lower end of the ash discharge component 33, and the side of the second flap 331 away from the circular furnace 2 cooperates with the third limit block 332, and the third limit block 332 can limit the lower end of the second flap 331 from flipping into the ash discharge component 33. It can be understood that when the ash and sewage in the smoke collecting ring pipe 32 enter the ash discharge component 33 under the action of gravity, after the gravity is sufficient to push the second flap 331, the lower end of the second flap 331 flips toward the circular furnace 2, and the ash and sewage return to the bottom of the circular furnace 2 through the ash discharge component 33. While ensuring the discharge of the flue gas flow, it can effectively prevent the smoke inlet component 31 and the smoke collecting ring pipe 32 from being blocked, thereby causing the pressure in the circular furnace 2 to increase, resulting in the exposure of flue gas and causing pollution.

[0044] The annular baffle 321 is vertically arranged on the inner wall of the smoke collecting ring pipe 32, and there is a gap between the lower end of the annular baffle 321 and the inside of the smoke collecting ring pipe 32. The smoke inlet assembly 31 is arranged on the side of the first flap 311 close to the circular furnace 2. It can be understood that when the ashes and sewage accumulated in the ash discharge component 33 do not submerge the lower end of the annular baffle 321, the smoke can enter the dust reduction mechanism 23 after passing through the gap between the annular baffle 321 and the smoke collecting ring pipe 32. When the ashes and sewage accumulated in the ash discharge component 33 submerge the lower end of the annular baffle 321, the smoke cannot enter the dust reduction mechanism 23 after passing through the gap between the annular baffle 321 and the smoke collecting ring pipe 32, so that the pressure on the side of the annular baffle 321 close to the circular furnace 2 increases rapidly, pushing the ashes and sewage downward, so that it pushes the lower end of the second flap 331 to flip toward the side of the circular furnace 2, and the ashes and sewage in the ash discharge component 33 quickly return to the circular furnace 2.

[0045] The smoke collecting mechanism 3 is connected to the first smoke pipe 13 through a dust reduction mechanism 23. Specifically, the dust reduction mechanism 23 includes a connecting pipe 231 and a dust reduction pipe 232, the dust reduction pipe 232 is connected to the smoke collecting ring pipe 32 through the connecting pipe 231, and the dust reduction pipe 232 is connected to the first smoke pipe 13. Correspondingly, a second smoke pipe 22 is provided on the top of the circular furnace 2, and the second smoke pipe 22 is connected to the connecting pipe 231 through a pipeline. It can be understood that the smoke from the smoke collecting ring pipe 32 and the second smoke pipe 22 entering the connecting pipe 231 rises to the dust reduction pipe 232, and in the process of rising, the ash will fall back into the ash discharge component 33 through the dust reduction pipe 232, the connecting pipe 231, and the smoke collecting ring pipe 32.

[0046] The feeding mechanism 4 is fixedly arranged on the frame 1, and the feeding mechanism 4 is connected to the circular furnace 2. Specifically, the feeding mechanism 4 includes a gate 41, a screw conveyor 42 and a third flap 43. The screw conveyor 42 is fixedly connected to the frame 1, and the gate 41 is fixedly installed at the feeding port of the screw conveyor 42. The discharge end of the screw conveyor 42 passes through the side wall of the circular furnace 2 and extends into the circular furnace 2. The upper end of the third flap 43 is hinged at the discharge end of the screw conveyor 42. It can be understood that after the gate 41 is opened, the garbage is fed into the feeding end of the screw conveyor 42 manually or by conveying equipment, the screw conveyor 42 transports the garbage into the circular furnace 2, the garbage pushes the third flap 43, and the garbage is loaded into the circular furnace 2. At the same time, the third flap 43 and the gate 41 can prevent the smoke generated during incineration from being exposed to the incinerator through the feeding mechanism 4, and can also be placed in the incineration, and the air enters the circular furnace 2 through the feeding mechanism 4, thereby affecting the incineration of the garbage. The feeding of the incinerator adopts high-point parabolic feeding, so that the material has sufficient contact with the high-temperature flue gas rising in the furnace, and the wet material has a drying effect after the high-temperature flue gas, and falls into the incineration area, so that the garbage combustion is more stable.

[0047] The oxygen supply device 5 includes a fan 51, a heat exchange tube 52 and a turbulent air pressure tube 53. The turbulent air pressure tube 53 is fixedly connected to the grate 21, and the upper end of the turbulent air pressure tube 53 extends into the circular furnace 2 until its upper end is located above the smoke inlet assembly 31. The heat exchange tube 52 is arranged in the dust reduction mechanism 23, and the turbulent air pressure tube 53 is connected to the air outlet end of the heat exchange tube 52 through a pipeline, and the air inlet end of the heat exchange tube 52 is connected to the fan 51 through a pipeline. It can be understood that after the garbage incineration starts, the air sent into the heat exchange tube 52 by the fan 51 will exchange heat with the flue gas in the dust reduction tube 232, and preheat the air in the heat exchange tube 52, which can increase the efficiency of garbage incineration after the turbulent air pressure tube 53 sends the air into the circular furnace 2.

[0048] Specifically, the turbulent air pressure pipe 53 is provided with a hood 531, a first aeration hole 532, and a second aeration hole 533. The hood 531 is fixedly arranged at the top of the turbulent air pressure pipe 53. The first aeration holes 532 are evenly arranged on the side wall of the turbulent air pressure pipe 53 along the circumference, and the second aeration holes 533 are evenly arranged on the top of the side wall of the turbulent air pressure pipe 53 along the circumference.

[0049] Correspondingly, the first aeration hole 532 is a horizontal through hole, and the second aeration hole 533 is an inclined hole inclined downward at 45 degrees. The first aeration hole 532 distributes air horizontally into the circular furnace 2. The mixing degree of the combustion flue gas and oxygen can be increased to make the combustion more complete. The first aeration hole 532 arranged in a 360° ring is matched with the vertical circular furnace 2, so that the degree of turbulence of this structural combination reaches 90%. In addition, the upper end of the turbulent wind pressure pipe 53 is provided with a second aeration hole 533 inclined downward at an angle of 45°, which can form a downward pressure wind curtain, allowing the flue gas to reflux in the furnace and move toward the smoke collection mechanism 3. The up and down winds make the garbage burn fully without the need for additional oil.
