Abstract

The invention discloses a plasma gasification furnace and a process for treating hazardous waste, comprising: a gasification furnace body, which comprises an integrally formed cylindrical upper part, an inverted truncated circular middle part and a cylindrical lower part, the upper Part of the inner wall and the middle part of the inner wall are provided with calcium silicate layer, corundum castable layer and high alumina castable layer, the total thickness of calcium silicate layer, corundum castable layer and high alumina castable layer is 300~ 500mm. The inner wall of the lower part is provided with a calcium silicate layer, a corundum castable layer and a chrome-containing brick layer, and the total thickness of the calcium silicate layer, the corundum castable layer and the chrome-containing brick layer is 300-500mm. The 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 and equipment for treating and utilizing hazardous wastes with good raw material adaptability, advanced technology, high gasification efficiency and no secondary pollution.

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...
