Description

Technical Field

[0001] The utility model relates to the technical field of garbage incineration power generation, and more specifically to slag recovery equipment for garbage incineration power generation. Background Art

[0002] A power furnace is a device that burns recycled garbage and converts the heat from the combustion into electricity to generate electricity. After the garbage incineration is completed, slag will remain inside the power furnace. After the slag is discharged, it needs to be recycled.

[0003] After searching, the existing patent (publication number: CN217451455U) discloses a slag recovery device for waste incineration power generation. During use, the collection cover is placed in the ash pile, and the side insert ring can be inserted into the ash pile, so that the sealing and stability of the lower end of the collection cover are greatly improved. Then, the high-speed mixer and the ash collection fan are started, so that the collection cover can suck the external ash into the inside, the side holes can absorb the ash on the side, and the bottom holes can absorb the ash at the lower end of the collection cover, which greatly improves the efficiency of the device in recovering ash. The absorbed ash enters the inside of the inner cover, and the high-speed rotating blades of the high-speed mixer stir the ash to prevent ash blockage. After the ash is sucked into the ash absorption pipe, it passes through the mixing pipe and the recovery pipe in turn, and finally enters the collection cabin inside the ash collection fan to complete the ash collection operation. However, in the process of realizing the utility model, the inventor discovered that the prior art had the following problems: the above-mentioned slag recovery equipment uses wind power to collect ash, but in actual operation, although the garbage has been screened before incineration, there are still some metals, glass and other substances in the garbage. This results in the presence of a small amount of solid slag such as metal and glass that is difficult to burn in the slag. These solid slag parts are difficult to crush, so in the process of wind attracting the ash, these solid slag parts are prone to block the pipeline, thereby affecting the safe use of the overall equipment.

[0004] In view of this, the utility model proposes a slag recovery device for waste incineration power generation, which solves this problem by collecting ash and solid slag separately. Utility Model Content
