Abstract

The invention discloses an intelligent monitoring device for preventing pulverized coal smoldering in a thermal power plant, and the device comprises a charging unit which comprises a charging base and a plurality of charging grooves uniformly formed in the charging base, wherein charging piles are symmetrically arranged in the charging grooves; and a monitoring unit which comprises a shell located in the charging groove and a monitoring assembly located in the shell. The device is provided with the charging unit, the monitoring unit, the information acquisition module, the electric quantity acquisition module and the processing module, through cooperative operation of the charging unit, the monitoring unit, the information acquisition module, the electric quantity acquisition module and the processing module, huge risks existing in a fuel system all the time are solved, and postmortem rescue is changed into beforehand early warning; the portable passive wireless device can be movably installed at any time as required, can be carried by a maintainer, can be reused, and can supervise key risk areas in a targeted manner every day, thereby greatly saving the safety supervision cost of an enterprise, and improving the safety management capability of the enterprise.

Description

technical field [0001] The technical field of thermal power plant systems that the present invention relates to, in particular, relates to an intelligent monitoring device and system for preventing pulverized coal smoldering in thermal power plants. Background technique [0002] The coal handling system of thermal power plants has a long front line, generally in centralized control operation, unattended on site, and the production method is continuous production in three shifts. During the production process, there is inevitably a certain amount of coal dust on site, some of which are hidden in the building. In the corners or crevices, despite the equipment cleaning and flushing system, it is difficult to clean them completely; according to the equipment defects, the maintenance professional of the fuel system will arrange a certain amount of maintenance work every day during the day, and there will be 1-2 on-site hot work on average every day point; after the hot work of th...
