It still includes installation frame 8, furnace body 1 sets up in installation frame 8, installation frame 8 has three-layer operation platform altogether, through operation platform can overhaul furnace body 1.
The furnace body 1 is characterized by further comprising a conveying device, wherein the conveying device comprises a support and a first conveying belt 9, and the first conveying belt 9 is arranged on the support and used for conveying materials into the furnace body 1.
The exhaust pipe 4 is arranged at the top of the furnace body 1, and one end of the exhaust pipe 4 extends into the airtight chamber 2.
The furnace body 1 is provided with a plurality of observation holes 10, and the observation holes 10 are uniformly arranged on one circumference of the surface of the furnace body 1.
The observation hole 10 is provided in the lower part of the furnace body 1.
The outer side of the furnace body 1 is provided with a fireproof layer 11, and the fireproof layer 11 is used for isolating the furnace body 1 from being in direct contact with the outside.
The lower end of the ash discharging valve 6 is also provided with a second conveyor belt 12, the recovery box 7 is arranged on the second conveyor belt 12, and the second conveyor belt 12 is used for carrying out secondary recovery on the residue discharged from the ash discharging valve 6.
The utility model discloses a sufficient theory of operation: a feed inlet 3 is arranged at the top of the furnace body 1, the material to be incinerated is fed into the furnace body 1 through the feed inlet 3, and a plasma torch 5 is arranged in the furnace body 1. The use of plasma torches 5 for waste treatment is prior art, for example: under the action of the plasma torch 5, the central temperature of the plasma torch can reach 2-3 ten thousand DEG C, and the edge temperature of the torch can also reach about 3 thousand DEG C. When the high-temperature and high-pressure plasma impacts the object to be treated, molecules and atoms of the object to be treated are recombined to generate new substances, so that the harmful substances are changed into harmless substances and even into reusable resources. Plasma waste treatment is therefore a waste decomposition and re-recombination process that converts toxic and hazardous organic and inorganic waste into valuable products.
