A hazardous waste incineration compatibility system based on off-line operation optimization

Abstract

The invention relates to a hazardous waste incineration compatibility system based on off-line operation optimization, including a hazardous waste databases, a module to be compatible, a compatibilitystrategy selection module and a compatibility module; by using the mixed integer nonlinear optimization method, the optimal compatibility scheme is calculated under the given limited conditions, Theresulting compatibility scheme can be exported as a user-friendly document for practical reference, The system can assist operators to quickly and simply carry out effective compatibility of various materials, thereby improving equipment operation efficiency, reducing temperature fluctuation caused by improper feed compatibility and equipment unplanned shutdown, and effectively improving the economic benefits of hazardous waste incineration.

Description

technical field [0001] The invention relates to the technical field of hazardous waste incineration treatment, in particular to a hazardous waste incineration compatibility system based on off-line calculation optimization. Background technique [0002] With the rapid development of my country's economy, industrial production capacity and people's living standards have been greatly improved, but at the same time, a large amount of solid waste has also been generated, which needs to be disposed of reasonably and properly. Among them, the special classification of hazardous waste should attract the most attention. Hazardous waste, as a special kind of solid waste, often has one or more characteristics that are potentially destructive to human health and the natural environment, such as toxicity, flammability, explosiveness, corrosiveness, and pathogenicity. . Among various hazardous waste treatment methods, incineration is the preferred treatment method for hazardous waste t...

Problems solved by technology

[0004] Although the rotary kiln incineration method is a widely used hazardous waste treatment technology, there are relatively high requirements for the temperature stability of the rotary kiln in the process of hazardous waste treatment. If the temperature is too high, the insulation layer in the furnace will be damaged, and a large amount of waste in the furnace will be damaged. Coking and slagging have a great impact on the service life of the rotary kiln; if the temperature is too low, the incineration of hazardous waste will be incomplete, and harmful substances cannot be effectively destroyed, resulting in excessive discharge and shutdown

However, in the actual operation process, due to the large fluctuations in the nature of the feed material, the incinerator will often be damaged by the high temperature of the furnace or the furnace temperature will be too low to require a large amount of auxiliary fuel to support the combustion, making it difficult to achieve stable and long-term economic operation of the rotary kiln incinerator.

The existing treatment process mainly relies on manual experience to carry out on-site compatibility and mixing of the feed materials. There is a lack of guidance. It is difficult to control the properties of the materials after compatibility, the element composition and the calorific value of the feed materials. It is prone to excessive or low furnace temperature and excessive emissions. Circumstances, resulting in unplanned downtime, resulting in significant economic losses
