Pollutant control process for treating hazardous wastes by using steelmaking converter

Abstract

The invention discloses a pollutant control process for treating hazardous wastes by a steelmaking converter. The pollutant control process is implemented by: cyclone dust removal; denitration treatment; waste heat treatment; rapid cooling; neutralization and adsorption; cloth bag dust removal; spraying and adsorption; and pollutant treatment. According to the pollutant control process, in the process that an exhaust chimney exhausts the flue gas, the concentration of CO and the concentration of CO2 in the exhausted flue gas are detected, the combustion efficiency of the hazardous waste during co-treatment in the steelmaking converter and a secondary combustion chamber can be conveniently calculated, and then the ventilation capacity of a combustion-supporting machine can be conveniently and rapidly regulated and controlled; therefore, combustion values in the steelmaking converter and the secondary combustion chamber are conveniently and reasonably regulated and controlled, the hazardous waste has a higher treatment effect in the actual treatment process, meanwhile, incineration heat of the hazardous waste can be effectively utilized when the hazardous waste is treated, the phenomenon of rapid combustion of hazardous wastes and combustible fuels due to an overhigh combustion value is avoided, and resource loss is prevented.

Description

technical field [0001] The invention relates to the technical field of hazardous waste treatment, in particular to a pollutant control process for treating hazardous waste in a steelmaking converter. Background technique [0002] Co-processing of hazardous waste by industrial kilns refers to the use of existing high-temperature industrial kilns, such as cement kilns, sintering machines, steelmaking converters, rotary kilns, and coal-fired boilers, to combine hazardous waste with other raw materials or Fuel co-processing, while meeting the normal production requirements of enterprises and ensuring product quality and environmental safety, realizes the harmless disposal and resource utilization of hazardous waste. In the process of co-processing of hazardous waste, hazardous waste forms a combustion Residue and flue gas, therefore, further treatment methods are needed to deal with the combustion residue and flue gas, so as to avoid the phenomenon that the pollutants produced a...

Problems solved by technology

[0004] The present invention provides a pollutant control process for steel-making converters to treat hazardous wastes, which can effectively solve the problem in the above-mentioned background technology that the products after incineration of hazardous wastes currently only have the processing capacity of conventional treatment means, so they are only limited to products after incineration of hazardous wastes. Carry out a series of treatments for the purpose of reducing pollution, so the current treatment technology is only limited to the level of treatment, so there is a lack of means for detection and analysis of incineration products, resulting in the inability to treat hazardous waste incineration products during the treatment process Carry out better analysis and understanding, so that people cannot timely and accurately grasp the combustion efficiency of the steelmaking converter and the combustion in the secondary combustion chamber, and then in the combustion process, when the combustion support is strong, the phenomenon of excessive combustion value is prone to occur , resulting in the rapid combustion of the combustibles, resulting in waste of excessive combustion heat and loss of resources, while the combustion-supporting force is too small, prone to the phenomenon that the combustion value is too low, so that the combustibles cannot be fully and completely combusted, which not only reduces The effect of disposal of hazardous waste is not guaranteed, but also because the combustion value does not meet the standard, it has an impact on industrial production
