foreword
With the rapid development of my country's productivity and the rapid rise of the economy, municipal solid waste, as a kind of biomass energy, can be burned for power generation, which can effectively save fossil energy.
construction background
With the acceleration of urbanization and the continuous improvement of people's living standards, the amount of municipal solid waste is also increasing year by year. Household garbage is "misplaced resources". Whether these "misplaced resources" can be handled well is related to the ecological environment of urban and rural human settlements. Comprehensive treatment and recycling are the inevitable requirements of urban development.
The most common domestic waste disposal methods are: landfill, composting and incineration. Compared with other treatment methods, domestic waste incineration power generation has the advantages of less land occupation, complete harmlessness, and high degree of resource utilization. Therefore, it is imperative to vigorously develop the research on municipal waste incineration technology and the development and application of equipment in our country.
System Overview
Show results
Based on the visualized online platform, this example constructs 3D models for waste incineration equipment, power generation equipment, and buildings. The 2D panel is linked to the 3D scene to help operation managers monitor parameters in real time in the form of charts, and use 2D configuration to display the process flow, assisting remote automatic control and Find problems in the operation process to meet the business needs of different managers.
system analysis
Using 2D configuration diagrams to restore the working principle of waste-to-energy, managers can more intuitively see the working status and detection information of each system, including temperature/pressure in the combustion furnace, steam drum pressure, turbine speed, flue gas concentration, etc.
Waste Incineration System
After the garbage enters the incinerator, it is fully burned at high temperature. The system combines the temperature measurement system to count the furnace temperature, boiler feed water temperature, flue gas temperature and steam temperature in the incinerator, and monitor the operating status of the slag treatment system and fly ash treatment system. Ensure that the fuel combustion energy in the furnace meets the needs of the boiler, maintain the safe and economical operation of the boiler, and maintain the stable operation of the incineration system.
Flue gas purification system
The process of the flue gas purification system commonly used in domestic waste power plants is "in-furnace denitrification system + semi-dry flue gas deacidification tower + dry powder injection + activated carbon injection adsorption system + bag filter". The flue gas is monitored through processes such as the flue gas generated by the incineration of the garbage, the flue gas treatment system, and the exhaustion into the atmosphere through the chimney after purification. The 2D panel updates the waste heat boiler steam pressure, steam temperature, feed water temperature, boiler blowdown rate, steam evaporation, and body resistance in real time.
Turbine Power Generation System
The heat energy generated by the complete combustion of the waste incineration system is converted into steam by the waste heat boiler, and then converted into electrical energy by the steam turbine generator, thus completing a series of energy conversions. The external structure and working status of the generator are presented through 2D configuration; steam flow, motor revolutions, power generation, motor temperature, etc. are displayed on the 2D panel and played automatically.
Security Management System
Supports the integration of data from the plant security management system, provides a picture of security situation monitoring, supports real-time monitoring of key parts of the plant, personnel, vehicles, alarm events and other elements, quickly displays and locates security alarm events, and retrieves surveillance videos around the event in real time , assist managers to effectively improve the effectiveness of plant safety control.
Energy management system
Supports the integration of energy consumption data in the plant area, real-time monitoring and multi-dimensional analysis of the production and operation status of various subsystems such as heating, water supply and drainage, energy consumption, and power supply in the plant area, supports energy consumption trend analysis, and comprehensive evaluation of energy consumption indicators to help managers Understand the energy consumption status of the park in real time, and provide a strong data basis for the rational allocation of resources, energy conservation and emission reduction in the plant area.
video surveillance system
It supports seamless fusion of video surveillance functions, conducts dynamic security monitoring of the factory area and its surroundings, and links with fire alarm, access control systems, personnel management and other systems to perform accurate positioning video camera viewing, and supports parallel viewing of multiple camera windows. Integrated with the video security monitoring system, the management personnel can view the on-site situation through real-time video, and the operation and maintenance personnel carry out real-time, transparent, process-oriented and globalized visual management of the factory area.

Development Technology
Taking the waste incineration plant as the object, relying on the self-developed Sovit2D/Sovit3D visualization platform, it highly restores the real 3D scene of the factory area, and monitors the equipment, personnel, buildings, environment, security and other elements of the factory area in real time. Visually display the implementation progress of waste incineration, environmental monitoring, equipment operation status, control status of flue gas pollutants, etc., and realize the visual management and application of production data of waste incineration plants.
construction value
The 3D visualization system of the smart waste incineration plant is based on the concept of "full life cycle management, integration of management and control, and high degree of information integration", with the structure of "smart equipment layer, smart control layer, and smart management layer", using the Internet, Internet of Things, artificial intelligence , big data analysis, cloud computing, mobile applications, virtual reality and other technologies, conduct in-depth analysis of waste incineration power plant systems and data, so as to be "perceivable, predictable, analyzable, and monitorable" to "safer, more Efficient, greener and smarter" is the goal of production and operation.
Summarize
As an industry with dual emission reduction effects, domestic waste incineration power generation has significant advantages compared with traditional landfill disposal and composting disposal. It meets the current "double carbon" goal, and exploring the green value of waste incineration power generation industry has become a development focus. The 3D visualization system for smart waste incineration power plants starts from optimizing the operation of domestic waste incineration power plants, and introduces new technologies such as visualization and big data into production and application links to effectively improve the stability of waste incineration.
