1. Background

At present, China is developing towards a “strong cement country”. The development trend of the international cement industry is centered on high performance, energy saving, low consumption and increased productivity by following the road of sustainable development, so the development of co-processing of solid waste in the cement industry is of great significance in China. The process of cement co-processing production includes solid waste collection, storage, conveying, metering, feeding, calcination, combustion gas monitoring and other like. In general, the choice of feeding point includes main burner, decomposition furnace, preheater, etc., in order to ensure that the solid waste can be completely burned, and at the same time, to minimize the impact of the input of solid waste on the cement process, currently the solid waste is generall put into the furnace after pre-combustion. During the entire feed pre-combustion process, it is necessary to monitor the skinning status and the feeding and combustion conditions in the furnace. The main existing problem is that the pre-combustion furnace is closed, and the smoke and dust are too massive to observe the internal combustion through the external observation hole.

2, plan

The system is mainly composed of a probe, a control box and a back-end decoding and display device, and is aimed at the small space of the feed port combustion furnace for the co-processing of hazardous waste and the air cannon’s influence on the internal working conditions, the wide-angle probe is used to improve the field of view, and the direct impact of the air cannon on the imaging probe is avoided by reasonable selection of the opening position. The structure adopts a well-sealed transmission imaging integrated probe. It has the functions of probe self-inspection protection, endoscopic high-definition imaging, and  outputing standard data.

3, value

● Improve process to achieve fine control of the production process;

● Real-time monitoring of the scaling and combustion conditions in the furnace to prevent clogging of the feed opening;

● Improve the efficiency of solid waste treatment, save energy, and increase the economic benefits.
