Description

Technical Field

[0001] The present invention relates to the technical field of slag removal devices, and specifically, it is a mesh belt type dry slag removal device.

Background Art

[0002] The core equipment of a dry slag removal system is a slag dryer. As a result of investigations, the slag dryers of current dry slag removal systems for coal-fired boilers in China's thermal power generation mainly use two types: mesh belt type (also called steel belt) slag dryers and scale bucket type slag dryers. The scale bucket type slag dryer has the disadvantage that the manufacturing process of its conveyor belt is complex, and the mesh belt type slag dryer has a high failure rate. In a comprehensive comparison, the scale bucket type slag dryer is superior to the mesh belt slag dryer.

[0003] Existing dry slag removal systems are gradually replacing the original wet slag recovery systems. A dry slag removal system is a system that processes the slag at the furnace bottom using the self-absorption of air under the condition of not using water. After converting to a dry slag removal device at the furnace bottom, the slag at the furnace bottom (about 800 - 950 °C) exchanges heat with cold air in a dry slag conveyor, and can be heated to about 400 °C in the furnace air. The efficiency of the boiler can be improved by about 0.32% (theoretical preliminary estimate). The dry slag removal system can improve the efficiency of the boiler by about 0.32 percent. The furnace bottom slag further burns during the cooling process, and the carbon content of the furnace bottom slag can be reduced to about 0.2% - 0.3% before and after the transformation. Changing the wet slag system of a coal-fired power plant to a dry slag system is in line with China's energy conservation and environmental protection guidelines and policies.

[0004] However, the working environment of the dry slag removal device is generally inside the factory. Since the temperature inside the factory is high, the temperature of the air entering the slag removal device also becomes high, resulting in a poor cooling effect of the slag removal device. At the same time, impurities generally remain at the outlet of the slag removal device, so the operator needs to frequently clean the outlet of the slag removal device, increasing the operator's workload.
