一种多级式余压自适应分流型高速雾化减温器
By using a multi-stage residual pressure adaptive flow-dividing high-speed atomizing desuperheater, the steam pressure is regulated by a flow-dividing ring and a pressure-reducing pump. Combined with a hybrid design of Venturi tube and Laval nozzle structure, the problem of unstable atomization effect caused by the fixed nozzle structure of traditional desuperheaters is solved, and stable atomization and efficient cooling are achieved under steam pressure fluctuations.

AI Technical Summary
Traditional desuperheaters have a fixed nozzle structure, which results in a fixed direction of cooling water spray, making it difficult to adjust and lacking flexibility. They cannot adapt to fluctuations in steam pressure, leading to unstable atomization effects and making them prone to pipe erosion or equipment damage.
A multi-stage residual pressure adaptive flow-dividing high-speed atomizing desuperheater is adopted. The steam pressure is regulated by the flow-dividing ring and pressure reducing pump. The mixing time of steam and cooling water is increased by combining the Venturi tube and Laval nozzle structure. The mixing is accelerated by using reflux and swirl plate. The nozzle angle can be adjusted to control the atomization direction. Combined with high-pressure gas to assist atomization, multi-stage regulation is achieved.
It achieves stable atomization under fluctuating steam pressure, avoids localized overheating and uneven cooling of steam, improves cooling efficiency, and protects equipment safety.
