Problems solved by technology

The disadvantage of using this technology is that the atomization effect cannot be guaranteed to be stable.
When the atomizing spray gun is atomized, it is necessary to ensure that the pressure of the waterway matches the pressure of the compressed air. When the spray volume of the quench tower decreases and the speed of the pump decreases, the pressure of the waterway also decreases, while the compressed air remains constant, which will cause uneven atomization. Well, it may not even be possible to atomize

Description

technical field [0001] The invention relates to a full-scale electronic and electrical waste continuous pyrolysis incineration device and its incinerator [0002] The process belongs to the technical field of combustible hazardous solid waste disposal and incineration. Background technique [0003] The heat treatment and recovery technologies of electronic and electrical waste mainly include incineration, pyrolysis, gasification, and vacuum heat treatment. The pyrolysis incineration technology was first used to treat radioactive solid waste. At present, the research and development of pyrolysis incineration technology and equipment is mainly aimed at medical waste. There are few reports on the application of pyrolysis incineration technology to the treatment of electrical and electronic waste. Therefore, it is necessary to conduct in-depth and detailed research on the pyrolysis and incineration characteristics of electronic and electrical waste when the amount of material ...
