Garbage incinerator with flue gas filtration function

The invention relates to the technical field of incinerator flue gas filtration and purification, in particular to a garbage incinerator with a flue gas filtration function. The garbage incinerator comprises an incineration mechanism, a placement mechanism, a collection mechanism, a shaking mechanism, a purification mechanism and a locking mechanism. Under the action of the incineration mechanism, garbage and sundries can be incinerated conveniently, exhausted glue gas can be filtered and purified conveniently, and meanwhile, the garbage and sundries can be placed in the incineration mechanism conveniently under the action of the placement mechanism; under the action of the shaking mechanism, dust and sundries fall into the collection mechanism through the placement mechanism to be stored, subsequent cleaning and recycling are facilitated, and secondary pollution is reduced; under the action of the purification mechanism, flue gas can be sufficiently adsorbed and filtered, external pollution of the flue gas i
