Description

Technical Field

[0001] This utility model relates to the field of coal coking technology, and in particular to a visualization device for experimental coke ovens. Background Technology

[0002] The quality of coke primarily depends on the quality of the coking coal, specifically its caking and coking properties. During the coking process, coking coal undergoes a process from dehydration to melting, and then to shrinkage and coking. Coal coke is formed layer by layer within the coking chamber of the coke oven. Adjacent layers at different coking stages have different temperatures and shrinkage rates. Therefore, the stress within the coke and semi-coke layers constantly changes. When this stress exceeds the strength of the porous structure of the coke, cracks form.

[0003] Patent application number 201410140390.2 discloses a system and method for real-time three-dimensional monitoring of blast furnace status, including sensors for detecting blast furnace body temperature, a PLC, a switch, a server, and a client. The server includes a data acquisition module, a furnace body temperature data analysis module and a hearth erosion line calculation module connected to the output of the data acquisition module, and a data storage module connected to the outputs of the furnace body temperature data analysis module and the hearth erosion line calculation module. The client includes a blast furnace three-dimensional model module and an interaction module connected to the data storage module; data from the blast furnace three-dimensional model module is output to the interaction module. However, this invention can only perform three-dimensional observation and monitoring of parameters such as blast furnace temperature, and cannot monitor the state of coking coal inside the furnace in real time.

[0004] Patent application number 201610016299.9 provides a method for visualizing the material layer distribution based on blast furnace radar data, capable of describing a three-dimensional visual graphic of the material layer during blast furnace charging and unloading. The method includes: acquiring measurement data from various measurement points using blast furnace radar; preprocessing the acquired measurement data to obtain the material surface descent rate during unloading; calculating the material layer descent rate based on the obtained material surface descent rate; obtaining the material layer distribution based on the calculated material layer descent rate; and fitting the material layer distribution trend in three dimensions—time, radial, and height—to obtain a three-dimensional visual graphic of the material layer distribution in time, radial, and height. However, this invention is applicable to the field of blast furnace ironmaking control technology, and obtaining the material layer distribution through the material layer descent rate is different from the real-time monitoring of coking coal conditions in this utility model.

[0005] Patent application number 202010826077.X discloses an online monitoring system for blast furnace burden shape. The system includes a connecting body with a first gas chamber, a first gas inlet, and a first gas outlet, both of which are connected to the first gas chamber and form a first cooling duct. An mounting body is connected to the connecting body and has a second gas chamber, a water chamber, a second gas inlet, a second gas outlet, a water inlet, and a water outlet. Both the second gas inlet and the second gas outlet are connected to the second gas chamber and form a second cooling duct, while the water inlet and the water outlet are connected to the water chamber and form a cooling water duct. The water chamber encloses a portion of the second gas chamber, and the first gas outlet is connected to the second gas chamber. A fixing frame is located at the second gas outlet and is used to fix a laser, with one part of the laser located within the first cooling duct and the other part within the second cooling duct. However, this invention's technical solution for monitoring the burden shape cannot determine the real-time reaction status of the coking coal in the blast furnace.

[0006] Patent application number 202111281461.7 relates to a blast furnace visualization and intelligent sensing platform. This platform utilizes big data analytics combined with mechanistic principles to intelligently model and visualize the dynamic performance of complex industrial processes, and to make intelligent optimization decisions for business management and production operations based on multi-objective dynamic constraints. It connects heterogeneous equipment and aggregates data, enabling edge or cloud computing through complete data acquisition and integration to enhance the connectivity of the industrial internet platform. However, while this invention employs mathematical algorithms and theories, and improves data modeling and big data analytics capabilities through numerous deep learning algorithms, thus enhancing equipment safety, it does not provide a direct visual representation of the reaction conditions inside the blast furnace.
