Garbage classification equipment, method and application based on chemical element characteristics

Abstract

The invention discloses garbage sorting equipment, methods and applications based on the characteristics of chemical elements. The steps of the garbage sorting method are as follows: the garbage is subjected to pretreatment such as bag breaking, crushing and screening, and the pretreated garbage mixture is placed in the On the garbage transmission device, the equipment for online real-time detection of garbage based on the characteristics of chemical elements detects and analyzes the garbage. The computer control system receives the signal detected by the detection equipment and sends instructions to the device for real-time classification of garbage. Classification. Apply the above-mentioned garbage sorting method to garbage recycling and preparation of raw materials with stable chemical element characteristics, recycle garbage, save resources, and prepare garbage into raw materials with stable chemical element characteristics. When these raw materials are used for pyrolysis and gasification In the process of burning and burning, it creates favorable conditions for the stable and effective operation of these processes, thereby realizing the purpose of waste reduction, resource utilization and energy utilization.

Description

technical field [0001] The invention relates to garbage sorting equipment, methods and applications, in particular to garbage sorting equipment, methods and applications based on chemical element characteristics. Background technique [0002] The composition of garbage varies with regions and seasons, and is unpredictable and controllable. When the garbage is used as fuel, the uncertainty and variability of the garbage lead to unstable operation of the boiler, large temperature fluctuations, incomplete combustion, and in severe cases, the boiler flameout or overheating damages the heat insulation material in the furnace. my country's waste usually contains high water and non-combustible substances, and the waste has a low calorific value and is unstable, resulting in unstable boiler operation, which requires auxiliary coal combustion to maintain operation. The data show that the high-level calorific value of the garbage received varies greatly with time, the lowest is about...

Problems solved by technology

Another problem in the current waste incineration treatment is that because the waste contains substances with high chlorine content such as polyvinyl chloride plastics and table salt, HCl and Cl are generated during the combustion process. 2 , not only lead to severe corrosion of the boiler, but also when the latter and the polyphenol components produced by incomplete combustion of garbage flow in the tail flue (especially when flowing through the electrostatic or bag dust collector), the De Novo synthesis reaction occurs , increase the generation of dioxin / furan toxic gas

At present, the main treatment method of solid waste is landfill, which not only pollutes the environment but also occupies our precious land resources.
