Abstract
The present invention relates to a method for treating medical garbage. In the method, an incinerator for blowing air and catalyzing, incinerating and decomposing garbage is adopted in a high-pressure grade separation mode. Under the action of multiple-trace high-pressure air, multiple-ring vortex and turbulent motion is formed in the 850 to 1100 DEG C of the incinerator, and thus, the medical garbage can be quickly dried, incinerated and decomposed. Incinerated smoke gas flows in an electric arc generating furnace, and the medical garbage is incinerated and decomposed again at the high temperature of 1600 to 1700 DEG C in the oxygen atmosphere. Thus, organic substances, stench, bacteria and harmful substances generated by decomposing the organic substances, the stench, the bacteria in the garbage are fully decomposed. After incinerated smoke gas flows through a series of purifying devices, smoke dust and decomposition products generated by incinerating the garbage, such as HCI, SO2, NO<X>, CO2, water, etc., in the smoke gas are removed step by step. Purified tail gas is returned to the electric arc generating furnace to be continuously treated with internal circulation.
