Problems solved by technology

[0003] At present, at least half of the heat in industrial production is directly discharged into the atmosphere in various forms of waste heat. These discharged and unused heat not only increase the production cost of the enterprise, but also cause serious pollution to the environment, which is not conducive to the economy. healthy development of society

Abstract

The invention relates to a metal and nonmetal high temperature smelting device and a method. The metal and nonmetal high temperature smelting device comprises a reducing furnace, a hydrator, a centrifugation separator, a liquid solid separator, a carbonization reactor, a Covapor unit, a ferrosilicon separator, a transformation separating system, an ammonification separator, and an amine hydrogen system. Coke powder, coal powder or organic carbides in garbage are subjected to combustion reaction with pure oxygen in the reducing furnace to generate high temperature, and reductive carbon monoxidegas, ferrosilicon, and heavy metals are generated; carbon monoxide is used for producing hydrogen in the amine hydrogen system, high temperature waste heat from the reducing furnace is introduced into the Covapor unit for electricity generation, generated electricity is provided for the reducing furnace to use; a mixture of ferrosilicon and nonmetal from the reducing furnace is introduced into the ferrosilicon separator to generate ferrosilicon and heavy metal products through separation. The Covapor unit and the amino hydrogen system are used for heat energy recycling, so that waste heat utilization rate is increased; the reducing furnace is used for reduction recycling of metal and nonmetal substances, waste is changed into valuables, and full utilization of natural resource is realized.

Description

technical field [0001] The invention belongs to the technical field of metal and nonmetal production, and relates to a device and method for high-temperature smelting of metal and nonmetal. Background technique [0002] Energy is an important material basis for the survival and development of human beings. Under the background of rapid industrial development, rising energy consumption on a global scale, energy shortage and intensified greenhouse effect, the development of a low-carbon, environmentally friendly and environment-friendly economy has become an inevitable choice. . Energy conservation and emission reduction, and the development and utilization of new energy-saving technologies are regarded as the "fifth conventional energy source" after coal, oil, natural gas, and hydropower. tension, to achieve sustainable development, and ultimately achieve the coordinated development of resources, environment, economy, and society. At present, my country's economy is in a pe...
