Problems solved by technology

[0003] At present, the drying methods of domestic garbage are mainly: mechanical extrusion and thermal evaporation; the effect of the former is limited by the unevenness of garbage particles, and the drying effect is not ideal; the latter usually needs to consume external heat energy, causing resource and cost problems
Due to low energy consumption and low pollution, biological drying method will become the trend of drying methods in the future. However, factors such as temperature, humidity, oxygen content, ventilation rate and moisture content will affect the drying effect

Abstract

The invention belongs to the field of environmental engineering. A method and device for optimal design of municipal solid waste drying, characterized in that the method can realize different The optimal design of the domestic waste drying parameters of components, and the determination of the conversion balance point of aerobic-anaerobic fermentation drying. The above optimization design method can optimize the drying process to make the drying stable and controllable.

Description

technical field [0001] The invention belongs to the field of environmental protection engineering, and in particular relates to an optimal design method and device for drying urban domestic garbage. Background technique [0002] Since the reform and opening up, with the rapid development of my country's economy and the acceleration of industrialization and urbanization, the output of urban garbage has also increased day by day, resulting in random piles of garbage, a large amount of land occupation, serious environmental pollution, and a large amount of waste of resources. At present, the annual output of urban garbage in my country is nearly 150 million tons, and it is increasing at a rate of about 8% every year. Nearly 2 / 3 of the cities are trapped in the dilemma of garbage siege. However, the direct sanitary landfill treatment of domestic waste will increase the water content of the landfill, and the stench produced by the fermentation of waste will also cause secondary p...
