Method for quickly calculating heat value of waste incineration on line

Abstract

The invention discloses a waste incineration heat value online rapid calculation method. The method comprises the steps: collecting the real-time temperature and humidity data and waste fermentation time data of a waste pool, and collecting the real-time temperature data and air chamber pressure difference data of fire grates of all sections of a combustion chamber; inputting the historical data in a database into a data model formula to be automatically compared with the collected real-time data, rapidlly analyzing the garbage heat value of a certain area through big data statistics and the data model formula, and directly regulating and controlling the fire grate speed and the fan opening degree under the support of rapidly analyzing the garbage heat value, and achieving the best combustion working condition, so it is guaranteed that the waste incineration treatment effect and the pollutant emission index meet the national relevant standard requirements. After the heat value of the garbage is rapidly analyzed, the garbage enters the adjusting link of the garbage incinerator control system, the garbage incineration efficiency is improved, and the treatment requirements for harmlessness, reduction and recycling of the garbage solid waste are met.

Description

technical field [0001] The invention relates to the field of garbage disposal, in particular to a method for fast online calculation of the calorific value of garbage incineration. Background technique [0002] With the development of the economy, the increase of the population and the acceleration of the urbanization process, the output of domestic garbage is increasing day by day. Waste incineration power generation is the preferred method for rapid, large-scale, and environmentally friendly disposal under current technical conditions. With the enhancement of people's awareness of environmental protection, the requirements for pollution prevention and control are becoming increasingly stringent. Pollutants from waste incineration power plants have a serious impact on the environment and the human body. Heavy metal ions, dioxins, toxic and harmful gases, etc. enter the human body through the atmosphere, water, and food chain, and are difficult to get rid of. They will accu...

AI Technical Summary

Problems solved by technology

Its commonly used unit: kilocalorie / kg (kcal / kg), it is difficult to carry out accurate statistics in large quantities due to the complex composition of garbage and the great uncertainty, and it is impossible to calculate the calorific value of combustibles like oil, coal, and gas-fired power plants Accurate analysis and calculation

It takes a lot of manpower and material resources to accurately know the calorific value of waste from sampling to measurement and calculation. Due to the complex process, long measurement cycle, and high cost, the waste calorific value statistics and waste calorific value analysis of waste incineration power plants are not available. large scale application

Only a small amount of sporadic sampling and measurement can be carried out, and continuous and reliable data cannot be provided. Traditional sampling and analysis methods have little significance in guiding the operation and regulation control of waste incineration power plants
