Embodiment 1

[0055] refer to Figure 1a , is a schematic diagram of a plasma furnace with a rectangular cross-section layout for plasma-enhanced pyrolysis of organic waste. The plasma furnace includes a furnace body 10, the inner side of the furnace body is provided with a furnace lining made of alumina refractory material and a thermal insulation layer, the furnace wall is provided with a feed inlet 1, and two Plasma torch 2, plasma torch is installed on the rotating device, and this rotating device is that plasma torch 2 is installed on a metal water-cooled sphere 21, and water-cooled sphere 21 is positioned on the water-cooled base 22 that two hemispherical metals are made, installs plasma The base 22 of the torch is mounted on the plasma furnace body 10 . The water-cooled sphere 21 can rotate and rotate on the spherical base 22, the sphere's rotation angle ranges from 0 to 40 degrees, and the rotation angle around the center line of the plasma torch is 0 to 20 degrees to match the rot...

Embodiment 2

[0057] refer to Figure 1b , is a furnace type with a circular cross-section arrangement for plasma-enhanced cracking of organic waste, the plasma furnace includes a furnace body 10, and the inner side of the furnace wall of the furnace body is provided with a magnesia refractory lining and a thermal insulation layer, A cooling water jacket can be arranged outside the thermal insulation material. The furnace wall is provided with a feed port 1, and three plasma torches 2 are installed alternately on the furnace wall, and the three plasma torches are evenly distributed along the furnace circumference, and the axis of the plasma torch is at 80° to the normal direction of the circle. The angle of degree is 60 degrees with the furnace axis; to promote the flow of gas in the furnace and make the temperature distribution in the furnace even; the bottom of the furnace body is provided with a slag outlet 5, and the top of the furnace wall is provided with an exhaust port 4. The furna...

Embodiment 3

[0058] Embodiment 3, using the plasma furnace provided by the present invention to treat medical waste

[0059] The present invention used provides as Figure 1b The plasma furnace shown. The meat containing plastic, cotton yarn and other medical waste and simulated limbs is crushed to a size of 1-50 mm under the condition of being isolated from the outside world and maintaining a slight negative pressure of 0-50 mm water column, and then continuously and stably fed into the plasma through the feeder In the body furnace, the broken organic waste is pyrolyzed in the above-mentioned plasma furnace. The working gas of the plasma torch in the furnace is oxygen, and the total amount of oxygen is controlled so that the amount of oxygen in the furnace is equivalent to the complete combustion of organic waste. 5% of the required theoretical oxygen amount; add oxygen to control the cracking temperature at 1200-1500K, and increase the cracking temperature by increasing the oxygen suppl...

Abstract

The present invention relates to plasma reinforced organic waste cracking method and plasma furnace. The plasma furnace includes furnace body, furnace hearth with material feeding port, plasma torch, bottom slag hole, top exhaust port and at least one gas inlet port connected via gas cylinder via pipeline with valve. The plasma reinforced organic waste cracking method includes the pre-treatment of solid, semi-solid, liquid or gaseous organic waste, high temperature cracking the waste in the plasma furnace of the present invention, re-burning the cracked gas and purifying cracked gas before or after re-burning. The present invention has low power consumption, low cost in apparatus and running, stable and simple operation, and is suitable for treating various kinds of organic waste.

Description

technical field [0001] The invention relates to a plasma cracking method and a plasma furnace, in particular to a plasma enhanced cracking method for organic waste and a plasma furnace. Background technique [0002] Organic waste is not only extremely harmful in itself, but may also contain various other toxic and harmful components. For example, the bacteria and viruses carried by medical waste are highly infectious, and chemical waste contains toxic and harmful organic substances such as polycyclic aromatic hydrocarbons and polychlorinated biphenyls, so they must be effectively treated and disposed of. At present, the treatment of medical waste and other organic waste has become an important environmental protection issue, and all sectors of society pay great attention to harmless treatment methods. Traditional burial and stacking methods not only take up a lot of land, but also often cause hidden dangers due to improper handling, which may cause the spread of pathogens. ...
