Description

Technical Field

[0001] This invention belongs to the field of environmental management technology for steel enterprises, and relates to an integrated control system and method for gaseous and solid pollutant emissions from steel enterprises. Background Technology

[0002] Steel enterprises have long production processes and numerous solid waste generation points. Apart from smelting slag, most of the solid waste is byproduct of air pollution control, which has not yet been fully managed and utilized. This solid waste is highly discrete both spatially and temporally, and currently relies heavily on manual statistics. There is a lack of coordination between various stages, including measurement, testing, transportation, transshipment, and disposal. Information silos and isolated processes exist among different management departments, resulting in long-standing problems of low efficiency, significant delays, and poor effectiveness in on-site solid waste management. This leads to high environmental risks and makes it difficult to meet the needs of enterprises for green sustainable development and digital transformation. Therefore, this invention aims to establish an integrated system for the control of air and solid pollutant emissions, providing comprehensive intelligent management and decision support for enterprises to improve the level of refined solid waste management, achieve efficient utilization of solid waste, and reduce the risk of environmental violations. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide an integrated management system and method for controlling the emission of gaseous and solid pollutants, to connect the real-time data chain of pollution control, emission and circulation, to form an intelligent diagnosis and automatic optimization model based on big data analysis and machine learning, and to realize intelligent prediction and optimized scheduling from the source of waste generation, transit storage to the end of disposal.

[0029] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] The integrated management and control system for gaseous and solid pollutant emissions from steel enterprises includes an environmental digital map module, an intelligent scheduling and path optimization module, a risk early warning module, and a ledger management module, such as... Figure 1 , Figure 2 ;

[0031] The environmental digital map refers to the use of a plant-wide digital map (generally achieved through aerial photography, laser scanning, or 3D virtual modeling) to mark upstream dust removal facilities, plant roads and production layouts, and downstream solid waste treatment units (including their names, main functions, affiliated plant / unit, management unit, production status, and other key attributes) to achieve overall visualization. This is primarily achieved by establishing a plant-wide waste gas treatment information database, uniformly coding and naming dust removal facilities and their associated solid waste in each production unit, and electronically tagging them. Radio frequency identification (RFID), QR codes, barcodes, and sensors are used to mark the names, main functions, affiliated plant / unit, management unit, and production status of dust removal facilities, plant roads and production layouts, and solid waste treatment units.

[0032] Intelligent scheduling and route optimization refers to the automatic allocation and scheduling of solid waste generated upstream based on backend calculations, relying on frontend digital maps, and considering transit inventory information and the production status of downstream solid waste treatment units. (For example, if a downstream treatment unit is under maintenance or temporarily shut down, the system automatically adjusts the plan, arranging the relevant solid waste to other treatment units or intermediate warehouses for temporary storage, and then rescheduling it after the downstream resumes normal production.) At the same time, it automatically calculates the optimal route by combining the real-time road conditions within the plant, and then corrects and tracks the vehicle transportation status through real-time feedback from vehicle GPS and other positioning devices for dynamic adjustment.

[0033] Risk warning refers to pushing and alerting various abnormal information to the environmental protection map on the PC and mobile APP after the background judgment and analysis. Such information includes environmental emission indicators exceeding the standard, traffic congestion in the middle road, vehicle failure, emergency shutdown of downstream treatment unit, etc., so that production management personnel can keep abreast of the situation.

[0034] Ledger management refers to the collection, recording, classification, and summarization of various types of data and information, and then presenting them in chart form.

[0035] In this embodiment, each dust removal facility, solid waste treatment unit, metering system, testing and analysis system, transfer warehouse, and transport vehicle communicates with the integrated management and control system through a communication network, Internet of Things, or Internet.

[0036] The integrated control method for gaseous and solid pollutant emissions of the present invention specifically includes the following steps:

[0037] S1. Establish a plant-wide waste gas treatment information database and uniformly code and name the waste gas treatment facilities and associated solid waste of each production unit;

[0038] S2. Transform each air pollution control site and its associated solid waste into electronic tags to achieve automatic identification of solid waste names and batch information;

[0039] S3. Analyze the ways to utilize solid waste throughout the plant and solidify the standard operating procedures for solid waste treatment;

[0040] S4. Implement online positioning upgrades for solid waste transport vehicles to achieve real-time monitoring of vehicle trajectories;

[0041] S5. Implement online detection and real-time transmission upgrades for all waste gas emission points, and establish environmental monitoring points in key areas within the plant;

[0042] S6. Upgrade the metering system with information technology to achieve automatic identification and scanning of electronic tags for transported solid waste and real-time transmission of metering data;

[0043] S7. Connect to the testing and analysis system to synchronize information on solid waste names, chemical compositions, and inventory levels;

[0044] Solid waste is categorized based on its iron, zinc, and alkali metal content into: iron-free (valueless) solid waste, high-zinc (iron-containing) solid waste, low-zinc (iron-containing) solid waste, and high-alkali metal (iron-containing) solid waste. Figure 3 As shown.

[0045] Ferrous solid waste can be outsourced for treatment or reused within the plant. High-zinc iron-containing solid waste is sent to the dezincification line for treatment, low-zinc iron-containing solid waste is reused within the plant, and high-alkali metal iron-containing solid waste is sent to the washing line for treatment.

[0046] S8. Access the inventory information and operating status of the transfer warehouse and each solid waste treatment unit. The transfer warehouse can be divided into two types: warehouse storage and ground storage, depending on the type of solid waste. Dry powder solid waste is loaded into the silo and its inventory can be monitored by the level gauge. Wet mud solid waste can be predicted by establishing a three-dimensional model of the material pile through laser scanning. At the same time, it can be combined with the weighbridge measurement data in the plant for correction processing.

[0047] S9. Build a digital environmental protection map for the entire plant, and establish a data management ledger for the entire process of waste gas treatment and solid waste transfer. Connect the real-time data chain of pollution treatment, emission and transfer, and form an intelligent diagnosis and automatic optimization model based on big data analysis and machine learning. Realize intelligent prediction and optimized scheduling from the source of waste generation, intermediate storage to the end of disposal, and present it in a visual way. At the same time, build a risk early warning system to complete the integrated treatment, management and control of gaseous and solid pollutants.

[0048] In this embodiment, the control of air pollutant emissions is mainly achieved through a continuous emission monitoring system (CEMS) for stationary pollution sources. If the emissions of gaseous pollutants exceed the environmental protection limit, an early warning will be issued immediately and promptly pushed to relevant production management personnel. At the same time, feedback will be given to the transfer and dispatch system so as to deal with production reduction and other situations in advance.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
