Abstract

The present invention discloses a plasma gasification furnace for treating hazardous waste and a process. The comprising plasma gasification furnace comprises a plasma gasification furnace body, wherein the plasma gasification furnace body comprises an integrally-formed cylindrical upper part, an inverted-circular-table-shaped middle part and a cylindrical lower part; both the inner wall of the upper part and the inner wall of the middle part are provided with calcium silicate plate layers, corundum castable layers and high alumina castable layers; and sum of thicknesses of the corundum castable layers and the high alumina castable layers are 300-500 mm. The inner wall of the lower part is provided with a calcium silicate plate layer, a corundum castable layer and a chrome-containing brick layer; and the sum of thicknesses of the calcium silicate plate layer, the corundum castable layer and the chrome-containing brick layer is 300-500 mm. A height ratio of the upper part, the middle part and the lower part is 70: (25-30): (30-35). The invention provides a plasma gasification process, which is good in raw material adaptability, advanced in technology, high in gasification efficiency and free of secondary pollution, for treating and utilizing the hazardous waste and equipment thereof.

Description

technical field [0001] The invention relates to an energy-saving and environment-friendly gasification furnace, and more specifically relates to a plasma gasification furnace and a process for treating hazardous waste. Background technique [0002] With the rapid development of the national economy, the output of hazardous waste in our country is increasing year by year. As of 2014, the annual production of hazardous waste has exceeded 14 million tons, and it is still increasing. The living environment will be seriously polluted and destroyed. [0003] Compared with general waste, hazardous waste has characteristics such as corrosiveness, leaching toxicity, acute toxicity, flammability, and infectivity. For the treatment of hazardous waste, the world and even my country have successively issued a series of laws and regulations. The treatment of hazardous waste is a key and difficult issue for the world. The common treatment methods of hazardous waste are divided into pretr...
