AI Technical Summary
Existing desuperheating and pressure reducing devices are prone to thermal shock under extreme operating conditions such as frequent start-stop and large load changes, leading to equipment damage and safety accidents.
The design employs a segmented, stable cooling system, including a vaporization chamber, a micro-mixing chamber, and a premixing chamber. Through multiple stable heat exchanges, combined with automatic nozzle angle adjustment, a bushing guide structure, and an inlet valve that automatically regulates the steam volume, efficient mixing of steam and water flow and temperature stability are achieved.
It improves the heat exchange stability and operating condition adaptability of the equipment, avoids equipment damage, extends service life, and ensures safety.
