AI Technical Summary

Technical Problem

Existing ash and slag removal systems for metallurgical waste heat boilers suffer from problems such as high-temperature ash and slag blockage, corrosion of crushers, poor sealing, and low safety, which affect the stability and safety of equipment operation.

Method used

It adopts a ash hopper and ground ash bin structure, combined with a high-power electric hoist driving a double flap valve. The electric hoist controls the ash and slag to enter the ground ash bin. The flap valve plate is made of high-temperature resistant and corrosion-resistant material, the guide wall design improves the impact resistance, and the sealing door ensures airtightness. The electric hoist drives the flap valve and the sealing door to open and close in coordination to ensure safety.

Benefits of technology

It enables safe centralized collection and temporary storage of high-temperature ash and slag, improves sealing and driving force, prevents flue gas leakage, enhances the equipment's impact resistance and ash removal efficiency, and ensures operational safety and system stability.
