1. Background and meaning

The cement industry is an important basic industry for the development of the national economy It is widely used in civil engineering, water conservancy, national defense and other projects, and has played an important role in improving people's lives, promoting national economic construction and national defense security. The main process of the cement production process is to crush and grind the raw materials into raw materials, and then send the raw materials to the high-temperature kiln to burn the mature materials with fuel, and finally mix the clinker and appropriate amount of gypsum to make cement. , It needs to go through multiple processes such as mining, raw material crushing, clay drying, raw meal grinding, clinker burning, clinker cooling, cement grinding and finished product packaging. In order to realize the automation and intelligent control of the cement production process, it is necessary to realize online monitoring of the temperature, gas, composition, etc. in the production process, to reflect the production status and equipment status in real time, and to improve production efficiency, ensure equipment safety and reduce pollution emissions. Effective protection.

2, plan

● Temperature monitoring: kiln calcining belt, grate cooler interior and outlet clinker, rotary kiln carcass, secondary air, tertiary air, kiln tail gas chamber

● Image monitoring: kiln head flame, grate cooler 1st stage, grate cooler 2nd stage, drum water level

● Gas monitoring: kiln tail smoke chamber, calciner outlet, preheater outlet, coal mill bag dust collection outlet, pulverized coal bin, denitrification ammonia escape

● Granularity detection: cement mill, raw meal mill, coal mill

3, value

● Replace manual inspections to reduce labor intensity and safety risks;

● Real-time reflection of the production process status, assist in optimizing control, improve production efficiency, and control product quality;

● Monitor the status of key equipment to ensure the safe and long-term operation of equipment;

● Monitoring the gas composition helps reduce environmental emissions;
