Waste incineration equipment with flue gas self-collection function, and waste incineration method thereof

The invention provides waste incineration equipment with a flue gas self-collection function, and a waste incineration method thereof. The waste incineration method comprises the following steps that (S1) waste recycling, specifically flatly laying waste on a recycling assembly line and recycling the waste, and recycling metal, such as scrap iron; (S2) fine crushing of the garbage, specifically pouring the recycled waste into a crusher, and finely crushing the waste; (S3) waste incineration, specifically, taking out the finely-crushed waste and putting the waste into an incinerator, and incinerating the waste; and (S4) flue gas collection, specifically absorbing flue gas generated during waste incineration through a flue gas collection box, and discharging the absorbed flue gas through the flue gas collection box. According to the waste incineration method, the waste is firstly screened to remove the scrap iron, and then the recycled waste is conveyed into the crusher, and screened and crushed at the same tim
