一种用于含氰废水的破氰系统
By using a heat-conducting plate partition structure and a delayed steam introduction method in an external steam mixer, cyanide-containing wastewater is preheated and mixed with steam through consistent injection. This solves the problems of gas-liquid phase change and hydrogen cyanide volatilization caused by direct steam mixing, and improves flow field stability and reactor utilization.

AI Technical Summary
In existing technologies, when steam is directly mixed with cyanide-containing wastewater inside the reactor, it leads to drastic gas-liquid phase transition, poor flow field stability, increased risk of hydrogen cyanide volatilization, and reduced reactor utilization.
An external steam mixer is used, with a heat-conducting plate partition structure and a delayed steam introduction method. The cyanide-containing wastewater is preheated first, and the temperature is gradually increased. Then, it is mixed with steam injection in the mixing chamber to ensure consistent flow direction and reduce violent gas-liquid phase change and hydrogen cyanide volatilization.
It improves flow field stability, reduces the risk of hydrogen cyanide volatilization, enhances mixing efficiency, and increases the effective utilization rate of the reactor.
