Problems solved by technology
However, the main gasification technologies currently used not only have high construction, operation and maintenance costs, but also the incineration devices usually use fuel oil, gas or coal as heat sources to support combustion
This not only consumes a lot of energy, but also has low thermal efficiency, and it is easy to cause shutdown accidents due to coking, and the cost of flue gas treatment is relatively high.

Embodiment
[0037] Such as figure 1 Shown is the thermal plasma waste incineration device of the present invention, including: an incinerator 9 and a second combustion chamber 12, the incinerator 9 communicates with the second combustion chamber 12, and the garbage goes to the second combustion chamber 12 after being burned by the incinerator 9 To remove residual organic matter, the temperature of the incinerator 9 is controlled at 700-900°C (adjust and set the temperature according to the working conditions). Under this temperature condition, the garbage can be dried, and part of the garbage can be cracked, gasified and carbonized. Cracked tar, dioxin and other substances can also go to the lower secondary combustion chamber 12 for further cracking and gasification. The working temperature of the secondary combustion chamber 12 is controlled at 1200-1500°C (adjust and set the temperature according to the working conditions). A plurality of thermal plasma torches 4 are arranged inside the...

The invention provides a thermal plasma waste incineration device which comprises an incinerator. The incinerator is connected with a secondary combustion chamber, after being incinerated through the incinerator, waste goes to the secondary combustion chamber so as to remove residual organic matter, the incinerator comprises an upper incinerator body, a lower incinerator body and a material channel communicating the upper incinerator body with the lower incinerator body, and the width of the material channel is smaller than that of the upper incinerator body and that of the lower incinerator body. Multiple plasma torches are arranged in the incinerator and the secondary combustion chamber, and the flame core temperature of the plasma torches is 3000 DEG C or above. According to the thermal plasma waste incineration device, waste is incinerated through the thermal plasma technology, the incinerator can be automatically shut down after reaching the preset temperature, sufficient energy saving is achieved, smoke generated after incineration can enter the secondary combustion chamber to be further recycled, and therefore the smoke is effectively treated, and the treatment cost is low.
Description
technical field [0001] The invention relates to the field of waste incineration treatment, in particular to a thermal plasma waste incineration device. Background technique [0002] In the prior art, there are three main treatment methods for domestic waste: landfill, incineration and composting. At present, the leading domestic waste treatment method is landfill. With the continuous optimization and adjustment of waste disposal structure, incineration treatment has gradually become the mainstream of the market. Compared with the high cost investment and potential secondary pollution risks of surface and groundwater resources for subsequent closure restoration and daily anti-seepage maintenance of landfill treatment, as well as the high cost and low return of composting treatment project construction and heavy metal pollution caused by the treatment process, Incineration treatment has overwhelming advantages over the previous two treatment methods in terms of economic benef...
