Description

Technical Field

[0001] The utility model relates to the technical field of incinerators, in particular to an anti-skid material device for a large-capacity mechanical domestic garbage incinerator. Background Art

[0002] Incineration of domestic waste for power generation is currently the most mainstream method of waste reduction and hazard treatment. The core equipment of this treatment process is the mechanical grate. Mechanical grate waste incineration power generation technology has the advantages of large processing capacity, high operating reliability, short treatment cycle, significant reduction, complete harmlessness and recyclable waste incineration waste heat. It is suitable for large-scale treatment of unsorted high calorific value urban domestic waste.

[0003] The garbage is poured into the garbage incinerator from the feed port, and the garbage enters the incineration grate in the incinerator for incineration through the reciprocating pushing action of the feeding grate. After the garbage is burned out, the remaining slag enters the slag discharge port and is discharged out of the furnace from the slag discharge port.

[0004] However, due to the diversity of sources of domestic waste, the complexity of its composition, and the seasonal fluctuations in its high moisture content, large-capacity mechanical grates cannot adapt well to these characteristics. The distance from the feeding grate to the chute is usually 1.1-1.45 meters. As the moisture content of the waste fluctuates and its composition characteristics change, the structural characteristics of existing incinerators cannot effectively prevent the movement of the waste in a controlled state, causing some of the waste in the chute to fall directly onto the incineration grate without the need for the feeding grate to move, resulting in waste sliding.

[0005] Sliding materials cause the material layer on the grate to accumulate and the thickness of the material layer to be uneven, which in turn leads to the deterioration of the combustion conditions and the failure to achieve the 3T+E combustion conditions, affecting the environmental emission of pollutants. This abnormal condition also brings difficulties to the incinerator's ACC automatic control system. Utility Model Content
