Small solid waste incinerator

The invention relates to the technical field of solid waste treatment devices, in particular to a small solid waste incinerator which comprises an incinerator body, a feeding port and a flue gas outlet, the feeding port is connected to one side of the incinerator body, the flue gas outlet is connected to the upper side of the incinerator body, and a pusher is fixedly connected to the position of the feeding port; a feeding hopper is connected to the pusher, and a combustor is connected to the side of the incinerator. A first smoke blocking wall and a second smoke blocking wall are arranged, under the same hearth volume, a smoke circulation path is lengthened, the stroke track of particulate matter is tracked through numerical simulation calculation, and the emission requirement that the staying time of smoke at the temperature of 850 DEG C or above is 3.2 seconds to the shortest and is larger than the staying time 2 seconds required by a standard is met; and through the arranged ash residue treatment mechanis
