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 incom

Abstract

The invention discloses garbage classification equipment and a garbage classification method based on chemical element properties as well as application. The garbage classification method comprises the following steps: carrying out pre-treatment including bag breaking, crushing, sieving and the like on garbage; putting a garbage mixture which is pre-treated on a garbage conveying device; carrying out detection analysis on garbage by using equipment for detecting the garbage on line and in real time based on the chemical element properties; receiving a signal detected by the detection equipment by a computer control system, and sending an instruction to a device for classifying the garbage in real time; and classifying the garbage. The garbage classification method is applied to garbage recycling and preparation of raw materials with the stable chemical element properties; the garbage can be recycled and resources are saved; the garbage also can be prepared into the raw materials with the stable chemical element properties; and when the raw materials are used for processes including pyrolysis, gasification, combustion and the like, and good conditions are created for stable and effective operation of the processes, so that the reduction of the garbage is realized, and the aims of recycling and energy generation are realized.

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...
