It should be understood that: the garbage is burnt on the receiving net 18, the aperture of the receiving net 18 is smaller than that of the grid net 6, and the garbage is prevented from falling from the receiving net 18 without being burnt. The trapezoidal cross section of the gas hood 20 is mainly to reduce the diameter of the gas head 19 and increase the pressure of the gas to be sprayed, thereby increasing the height of the flame for burning the gas. The dust cap 21 is provided on the top of the gas cap 20 to prevent ash generated by burning garbage from falling into the gas cap 20 and causing blockage, so that the burning operation cannot be performed. Moreover, during the combustion of the garbage, the gas introduced from the drying oven 40 into the incinerator 5 increases the combustion temperature of the gas, so that the garbage can be combusted more fully, and the generation of toxic and harmful gases is reduced.

The specific setting mode of the dust cover 21 is as follows: the gas cover is characterized in that protective covers 22 are symmetrically and fixedly arranged on the side wall of the gas cover 20, a connecting plate 23 is hinged to the side wall of the gas cover 20 in each protective cover 22, a spring 24 is fixed between the connecting plate 23 and the side wall of the gas cover 20, a supporting rod 25 is fixed to the top of the connecting plate 23, the other end of the supporting rod 25 is fixed to the dust cover 21, a strip-shaped through hole 26 for the supporting rod 25 to move is formed in the protective cover 22, the length of the strip-shaped through hole 26 is larger than the path of the dust cover 21 in the rotating process, and the two corresponding dust covers 21 cover the outlet of the. The specific process is as follows: after gas is introduced into the gas pipe 17, the gas enters each gas head 19, the dust-proof cover 21 is opened, the gas is sprayed out from the gas cover 20 and is ignited at the same time, an ignition port is arranged on the side wall of the incinerator 5, and manual ignition is carried out through an igniter. And the ignition is in a conventional setting which can be carried out according to actual conditions. When the dust cap 21 receives the impact force from the gas cap 20, the connecting plate 23 compresses the spring 24, so that the two combined dust caps 21 are opened. After the gas cap 20 is no longer vented, the spring will exert a reaction force on the connecting plate 23, so that the two dust caps 21 are re-combined together to cover the outlet of the gas cap 20.

Furthermore, in order to avoid the garbage ashes falling from the receiving net 18 from being accumulated on the gas pipe 17, a dust cover 56 may be disposed on the gas pipe 17, the dust cover 56 is shaped like a Chinese character 'ren', and a through hole for the gas burner 19 to pass through is disposed, so that the garbage ashes slide down to the bottom of the incinerator 5 from the side wall of the dust cover 56, and the cross section of the bottom of the incinerator 5 is inverted trapezoid, thereby preventing the garbage ashes from being accumulated at the bottom of the incinerator 5.
