Description
Technical Field
The invention belongs to the technical field of solid waste power generation, and particularly relates to a novel multifunctional integrated system for integrated pollutant disposal and high-power steam turbine power generation, which is established by a supercritical water gasification technology and integrates household garbage, toxic soil and hazardous waste harmless treatment and high-power steam turbine safety power generation.
Background
Domestic garbage power plants burn and treat domestic garbage, and toxic soil and hazardous waste are treated by special mechanisms. The waste incineration power generation is a mode of treating urban waste at present, but zero emission is not achieved, aerial emission of harmful substances such as dioxin is not fundamentally stopped, and zero carbon emission is more difficult to realize. Along with the development of the world economy and the great development of the express industry and the E-commerce platform, the urban garbage amount rises rapidly. In addition, some chemical bases and surrounding soil in China are seriously polluted, and the underground water is also influenced. In the place where the garbage is buried, the leakage liquid also reaches the underground soil, and even pollutes the underground water. Therefore, the method has an incremental requirement for harmless treatment of toxic soil and hazardous waste. Here, the pollutants such as toxic soil and dangerous waste are not treated harmlessly in a garbage power plant which is a domestic garbage-based disposal site, but are treated in other special ways. After the landfill is dug again, the garbage is transported to a household garbage power plant. The surrounding soil and hazardous waste contaminated by the landfill waste are expensive to dispose of, and may be buried or not disposed of. Therefore, if the garbage power plant can treat a plurality of pollutants, the harmless treatment content is greatly increased due to the convenience of treatment together.
The main technologies of the current garbage incinerator of a garbage power plant comprise five technologies, namely a mechanical grate incinerator, a fluidized bed incinerator, a rotary incinerator, a CAO (regenerative incinerator) type incinerator, a pulse-jet incinerator and the like. The technology mainly popularized by the state mainly comprises a mechanical grate incinerator and an advanced pulse throwing incinerator, wherein garbage enters an inclined downward grate (the grate is divided into a drying area, a combustion area and a burnout area) through a feed hopper until the garbage is burnt out and discharged out of a hearth. Combustion air enters from the lower part of the grateAnd mixing with the garbage; the high-temperature flue gas passes through the heating surface of the boiler to generate hot steam, meanwhile, the flue gas is cooled, and finally, the flue gas is discharged after being treated by the flue gas treatment device. Whatever advanced incinerator is adopted in the garbage power plant, the garbage incineration has the requirement of waste gas treatment, such as dust, hydrogen chloride (HCl) and sulfur dioxide (SO) 2 ) Nitrogen Oxide (NO) X ) Carbon monoxide (CO), organic pollutants, dioxins and heavy metals. The flue gas generated by burning the garbage coexists with carbon dioxide, harmful gas and heavy metal, and the requirements of carbon-free, harmless and zero-emission environmental protection and 'double-carbon' policy are difficult to meet. The waste heat boiler for burning the garbage is polluted and corroded by materials, the power generation capacity is limited, and the economic scale and the economic benefit of a garbage power plant are influenced by the technical factors. The garbage incineration does not realize zero emission, and the living development space of a garbage power plant is also influenced.
The invention is based on establishing a brand-new system of harmless treatment of domestic garbage, toxic soil and hazardous waste-safe power generation of a high-power steam turbine, designing and applying a high-power steam turbine power generation system with no carbon and no smoke dust and zero emission of 100MW or above, making fundamental breakthrough and innovation on the products and technologies directly related to carbon discharge of the current garbage incineration generator set, and meanwhile, a garbage power plant can be compatible with, expand the range of pollutant treatment and update treatment means, so that no carbide, smoke dust and harmful pollutants are discharged to the sky, thereby benefiting the human society.
As for how to graft the supercritical water gasification technology to the garbage power plant, the traditional mode of garbage incineration after landfill is completely changed, the garbage power plant does not have a large chimney because the garbage incineration is carried out by open fire, the boiler is saved, the domestic garbage, the toxic soil and the dangerous waste can be directly and simultaneously treated by applying the supercritical water gasification technology, the emission of secondary pollution after the incineration of garbage such as dioxin, carbon dioxide and other harmful gases is fundamentally stopped, and the investment of the treatment part of the harmful gas and the leakage liquid is saved.
