Solid waste homogeneous modified gasification clean power generation treatment method

Abstract

The invention relates to a method for simultaneously carrying out reduction, harmless and resourceful processing on multiple mixed solid wastes and generating electric energy in a cleaning manner. The method comprises technologies such as a sorting technology, a crushing technology, a homogeneity modified technology, a gasification cleaning electricity generation technology and a carbon recycling technology. The method comprises the steps of enabling the solid wastes to enter a homogeneity modified process through preprocessing processes such as the sorting process and the crushing process, enabling the uniform material the property of which is changed to enter a high temperature gasification process, decomposing a solid state organic matter into the clean fuel gas state at high temperature, burning the fuel gas through a combustor introduced with oxygen at 1200 DEG C, or carrying out electricity generation through the combustion of a fuel gas unit, enabling overheating flue gas to pass through a boiler to carry out secondary electricity generation by using a steam turbine, discharging the flue gas and filtering the flue gas through desulfuration and a cloth bag, and recycling organic carbon from the gasified residues through a carbon recycling unit. The method provided by the invention has the advantages that a pollutant is solidified, a dioxin generating condition is eliminated, the tail gas is clean, a percolate does not need to be independently processed, the electricity generation capacity is large, the benefit is high, the output waste residues are inert residues, and the pollutant is not dissolved out.

Description

1. Technical field [0001] The invention relates to a treatment method for homogeneously modified gasification of solid waste for clean power generation, in particular to a method capable of improving the form and properties of various mixed solid wastes, so as to include: urban domestic garbage, corn stalks, Wheat straw, cotton straw, garden waste, general hospital waste, sludge generated during sewage treatment, etc., or any or all of the solid waste mixtures are reduced and harmless treated and produced in a clean way A method for resourceful processing of electric energy. 2. Background technology [0002] General solid waste in cities or rural areas usually includes urban domestic waste (such as residential area waste, office area waste, streets, garden waste, etc.), agricultural waste (such as corn stalks, wheat straw, cotton stalks, etc.), general hospital waste, sewage Sludge and other types generated during the treatment process. [0003] At present, these different...

Problems solved by technology

However, since the original solid waste material often has the characteristics of high moisture content, high entanglement, and large property changes, the pyrolysis process cannot be completely carried out when it is directly fed, so the pyrolysis temperature cannot be raised above 650-700 ° C, and the organic carbon cannot be completely processed. Decomposition, so the heat recovery rate is low and the treatment effect is poor

After adding a large amount of additional fuel (such as diesel oil), although the temperature of the cracking process can be guaranteed, a large amount of fuel is consumed, and the gain outweighs the gain

[0011] In addition, neither of these two technologies can treat multiple solid wastes at the same time
