AI Technical Summary

Technical Problem

Existing flow regulation devices in grate coolers suffer from poor linearity between opening and flow, unstable regulation, and are prone to jamming or sealing failure under high-temperature conditions. Furthermore, they lack a multi-valve coordination mechanism, making it difficult to optimize system energy consumption while ensuring equipment safety.

Method used

The design incorporates a multi-stage damping adaptive cooling intelligent flow regulating valve, which, combined with a regulating unit and valve plate, adjusts the flow rate by changing the airflow channel path and cross-sectional area. It is also equipped with a cooling channel and sensor group, and utilizes a control module to achieve conflict coordination and operating mode management.

Benefits of technology

It improves the linearity and stability of flow regulation, prevents valves from jamming due to high temperature, realizes intelligent optimization of air volume resources and rapid response to abnormal operating conditions, and enhances the operating efficiency and safety of the grate cooler.
