Oxygen-free sectional type pyrolysis furnace for household garbage

Abstract

The invention discloses an oxygen-free sectional type pyrolysis furnace for household garbage. The oxygen-free sectional type pyrolysis furnace comprises a heat preservation furnace body, a drying furnace body, a heat insulation furnace body, a pyrolysis furnace body, a carbon stripping furnace body and an ash deposition hopper, wherein the drying furnace body, the heat insulation furnace body, the pyrolysis furnace body, the carbon stripping furnace body and the ash deposition hopper are fixed in the heat preservation furnace body; heat insulation inserting plates are arranged among the drying furnace body, the heat insulation furnace body, the pyrolysis furnace body, the carbon stripping furnace body and the ash deposition hopper; the drying furnace body is used for drying the householdgarbage; the heat insulation furnace body can separate the high-temperature pyrolysis furnace body from the drying furnace body; the pyrolysis furnace body is used for pyrolyzing the household garbage; the carbon stripping furnace body is used for realizing separation of pyrolytic carbon in an oxygen-free state; the ash deposition hopper is used for pyrolyzing the carbon; an interlayer between thepyrolysis furnace body and the heat preservation furnace body is a combustion chamber; a gas supply system is used for conveying combustible gas generated by the pyrolysis furnace body into the combustion chamber and the ash deposition hopper; and a drying system can be used for conveying heat in the combustion chamber and the ash deposition hopper into the drying furnace body. According to the oxygen-free sectional type pyrolysis furnace, the utilization rate of the household garbage is increased, the garbage is changed into non-toxic gas and carbon ash after being combusted and decomposed,and the problem of secondary pollution is avoided.

Description

technical field [0001] The invention belongs to the field of domestic waste treatment devices, in particular to an oxygen-free segmented pyrolysis furnace for domestic waste. Background technique [0002] The existing domestic waste treatment technology generally uses domestic waste incineration to generate electricity. This technology incinerates the waste by adding a combustion enhancer, and then uses the remaining heat from the waste to generate electricity. This technology requires the establishment of a huge collection system. Garbage incineration power generation requires a large amount of combustion accelerants, and the operating cost is high. In addition, the waste incineration process will produce secondary pollution and generate dioxins, sulfides, and nitrogen that affect the environment. Oxides, chlorides, fly ash, etc. These pollutants will cause harm to the environment and the human body, and seriously affect human health. Therefore, solving the problem of ope...
