Abstract

The invention provides a process method for cooperatively treating hazardous waste through rotary kiln incineration and oxygen-enriched side-blown reduction smelting. The process method comprises the following steps that firstly, the hazardous waste is conveyed into a rotary kiln to be incinerated to obtain rotary kiln incineration hot slag; and then the rotary kiln incineration hot slag obtained in the previous step, a reducing agent and a flux are fed into a side-blown converter and then are subjected to reduction smelting to obtain matte alloy and solid waste. The process method for cooperatively treating the hazardous wastes through rotary kiln incineration and side-blown converter reduction smelting and a corresponding process device are provided, so that resource recycling of wastes of hazardous waste treatment and reduction and harmlessness of waste emission are realized, the advantages of being low in investment, energy-saving, consumption-reducing, low in operation cost, easy to popularize and the like are achieved, and reduction, harmlessness and resource recycling in a real sense are realized.

Description

technical field [0001] The invention belongs to the technical field of hazardous waste treatment and disposal, and relates to a process method and a process device for incinerating hazardous waste, in particular to a process method and a process device for synergistically treating hazardous waste with rotary kiln incineration and side-blown furnace reduction smelting. Background technique [0002] With the development of industry, the hazardous waste discharged from industrial production process is increasing day by day. It is estimated that 330 million tons of hazardous waste are generated worldwide each year. Public sensitivity to hazardous waste issues is high in many developed countries due to the high levels of pollution and potentially severe impacts of hazardous waste. Hazardous waste, referred to as hazardous waste, according to the "Law of the People's Republic of China on the Prevention and Control of Environmental Pollution by Solid Waste", hazardous waste refers...
