Problems solved by technology

However, the device occupies a large space, the linear system is not compact enough, and the temperature operation of the segmental control is complicated. Multiple sensors need to be controlled at the same time, and the heating rate and the stability of the temperature field in the microwave field are low.

Abstract

The invention discloses an improved compact waste heat-microwave high-temperature hydrothermal uninterrupted operation device and method. By arranging the microwave launcher and the reaction vessel in a ring, the heating rate and the stability of the temperature field in the microwave field are realized, which improves the stability of the microwave continuous operation system; at the same time, the ring track setting improves the compactness of the system and reduces the footprint area, space utilization is more reasonable. The opening and closing of the inlet and outlet of the reaction vessel is controlled by light sensing, combined with the automatic sampling system of gravity sensing-flow control, truly realizing the uninterrupted operation of the microwave high-temperature hydrothermal process. By recovering and utilizing the waste heat of the product after the reaction, the energy consumption and reaction time during the microwave heating period are reduced. In addition, the top and bottom of the reaction vessel are both designed to have zigzag planes, combined with the retractable sealing strip at the entrance and exit of the device, to avoid microwave leakage. The device is compact and reasonable, and is suitable for microwave high-temperature hydrothermal application of waste incineration fly ash and other solid waste.

Description

technical field [0001] The invention relates to an improved compact waste heat-microwave high-temperature hydrothermal uninterrupted operation device and method, and belongs to the technical fields of microwave application technology and waste incineration fly ash disposal. Background technique [0002] With the rapid development of the economy and the acceleration of urbanization, China is facing more and more severe problems of waste disposal. In 2017, China's municipal solid waste removal volume reached 215 million tons, a year-on-year (2016, 2.04) increase of 5.39%, and the amount of harmless waste disposal was 210 million tons, a year-on-year (2015, 197 million tons) increase of 6.60%. . [0003] As waste incineration becomes more and more common, the output of waste incineration fly ash in my country is also increasing. Fly ash contains a lot of toxic and harmful components such as heavy metals, chlorinated organic compounds, sulfides, and dioxins. Compared with deve...
