Coal distribution detection method and device

Abstract

The invention provides a coal distribution detection method and device, and the method comprises the steps: recognizing a plurality of pieces of raw coal, and obtaining the coal quality information corresponding to each piece of raw coal; obtaining to-be-paired labels with the same number as the multiple pieces of coal quality information from the bidding machine, wherein unique number informationis stored in each to-be-paired label; paring the multiple to-be-paired labels with the multiple pieces of coal quality information in a one-to-one mode, writing the coal quality information into thepaired to-be-paired labels to obtain multiple coal quality information labels, wherein the coal quality information labels are attached to the corresponding raw coal; and reading the coal quality information labels on a plurality of raw coals entering the raw coal bunker through reader-writers arranged in the raw coal bunker at intervals to obtain a plurality of pieces of serial number information. The RFID technology can be applied to the raw coal bunker, a scientific reader-writer arrangement method is provided, the coal distribution condition is precisely predicted in the raw coal bunker, the coal quality of the coal before entering the boiler for combustion is accurately speculated, and combustion of the boiler is assisted to be regulated and controlled.

Description

technical field [0001] The invention mainly relates to the technical field of coal tracer, in particular to a coal material distribution detection method and device. Background technique [0002] Coal is still used as the main energy source in my country today, and it is used for power generation by combustion, and coal quality has a great impact on boiler combustion efficiency and pollutants; implementing different combustion strategies in the furnace for different coal qualities can achieve the maximum utilization efficiency of coal combustion change. Therefore, before the coal enters the boiler for combustion, it is very important to predict the coal type and coal combustion characteristics. [0003] In the coal handling system of power plants, coal enters the raw coal bunker from the coal yard through coal crushers, iron removers and other equipment, and then enters the coal mill to meet the combustion requirements, and then enters the boiler through the pulverized coal ...

AI Technical Summary

Problems solved by technology

However, there are some deficiencies in the actual application of the system and the refined tracing of multiple coal types: first, the application of the system is relatively vague, and it is not clear how to scientifically arrange and apply the non-contact RFID (radio frequency identification) technology; When there are multiple types of coal in the pulverized coal bunker, the system cannot predict the complex distribution of coal, and thus cannot accurately predict the quality of the incoming coal for combustion regulation, and the refined identification information system has not been achieved.
