Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, specifically to an energy-saving and environmentally friendly waste-to-energy device. Background Technology

[0002] Waste-to-energy plants are environmentally friendly systems that use advanced technology to incinerate municipal solid waste at high temperatures. This process reduces waste volume (by 80%-90%) and renders it harmless (by destroying harmful substances and purifying flue gas). At the same time, it recovers the heat energy generated during incineration and converts it into electricity or heat energy, ultimately transforming waste from a pollutant into clean energy.

[0003] Existing waste-to-energy plants stir the waste piled up in the middle during incineration, but the stirring effect is generally poor. The waste in the very center is not easily stirred up, which further affects the overall efficiency of waste incineration. Moreover, when waste is introduced into the incinerator from top to bottom, it piles up from the middle to the surrounding areas, which puts a lot of pressure on the stirring mechanism and reduces its service life in the long run.

[0004] Therefore, a solution is needed. Utility Model Content

[0029] Solution Analysis:

[0030] 1. Regarding the mixing effect and incineration efficiency:

[0031] In the mixing mechanism 7, the distribution plate 78, when rotating, disperses the waste sliding down the guide plate 85 to all sides, achieving uniform descent. The baffle 75, in conjunction with the receiving seat 710, separates the middle of the bottom of the incineration zone. The rotation of the mixing plate 77 and the mixing rod 79 can fully agitate the waste outside the baffle 75, preventing concentrated accumulation. This design allows the waste to be more evenly distributed in the incinerator, enabling more thorough contact with the combustion air, greatly improving the overall efficiency of waste incineration and solving the problem of existing devices where waste in the middle is not easily dispersed, affecting incineration efficiency.

[0032] The grid bar 713 has a triangular prism structure, which allows ash to fall smoothly on the grid bar and pass through the filter screen 2 without obstruction, ensuring smooth ash removal and indirectly creating a good environment for subsequent waste incineration, which is conducive to maintaining a high incineration efficiency.

[0033] 2. Regarding equipment lifespan:

[0034] In the feeding mechanism 8, after the garbage is crushed by the crushing roller 82, it slides down to the distribution plate 78 under the guidance of the guide plate 85. The distribution plate 78 evenly disperses the garbage, so that when the garbage is introduced into the incinerator from top to bottom, it no longer piles up from the middle to the sides, which reduces the pressure on the mixing mechanism 7 and thus extends the service life of the mixing mechanism.

[0035] Working principle:

[0036] During operation, the stepper motor 73 is first started, causing the bottom components to rotate via the rotating shaft 74. Waste is fed through the two inlets 8, crushed by the crushing roller 82, and then guided by the guide plate 85 onto the distribution plate 78. The rotating distribution plate 78 disperses the waste, which is flowing downwards from the left and right, ensuring even descent. As the waste accumulates, the baffle 75, in conjunction with the receiving seat 710, isolates the middle of the bottom of the incineration zone, allowing the waste to be thoroughly agitated outside the baffle 75 by the rotation of the stirring plate 77 and stirring rod 79, preventing concentrated accumulation. After incineration, the ash passes through the filter screen 2 and falls downwards. Finally, driven by the motor 3, the ash is transported to the ash outlet 5 via the spiral feed rod 4. The ash falls smoothly and unobstructed over the triangular grid bars 713.

[0037] Technical effects of implementing this solution:

[0038] This energy-saving and environmentally friendly waste-to-energy device improves waste incineration efficiency and extends equipment lifespan by optimizing the mixing and feeding mechanisms. It can also recover the heat energy from the flue gas generated during waste incineration to generate electricity, while achieving waste reduction and harmless treatment, thus comprehensively realizing the goals of energy conservation, environmental protection, and efficient waste treatment.

These components are all general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that existing waste-to-energy devices stir the waste accumulated in the middle during waste incineration, but the stirring effect is generally poor. The waste in the very center is not easily stirred, further affecting the overall efficiency of waste incineration. Moreover, when waste is introduced into the incinerator from top to bottom, it accumulates from the center outwards, which puts a lot of pressure on the stirring mechanism, reducing its service life in the long run. This utility model improves waste incineration efficiency and extends the service life of the equipment by optimizing the stirring and feeding mechanisms. It can also recover the heat energy from the flue gas generated by waste incineration to generate electricity, while achieving waste reduction and harmless treatment, thus comprehensively realizing the goals of energy conservation, environmental protection, and efficient waste treatment.
