Gas-liquid separation device suitable for spray system

Abstract: The utility model discloses a gas-liquid separation device suitable for a spray system. The gas-liquid separation device comprises a spray tower, wherein a spray device, a filler layer and a gas inlet are sequentially arranged at the middle part of the spray tower from top to bottom; and a gas-liquid separation layer is arranged at the top of the spray tower. According to the gas-liquid separation device disclosed by the utility model, the gas-liquid separation layer is added to the top of the spray tower, gas flow is guided via a fixed impeller to generate a centrifugal vortex, the passing section area of the gas flow is reduced to increase the flowing speed of the gas flow and improve the centrifugal effect, so that liquid effectively contacts a gas-liquid separation surface to be separated, and arrives at a waste liquid drainage point via a flow guide device; the separation effect is not influenced by a wind speed and a wind pressure; and the adjustment is easy.

Optimization on inlet angle for spray tower of industrial boiler by numerical simulation

Abstract: Based on Fluent of the computational fluid dynamics(CFD),numerical simulation of spray scrubber of the wet flue gas desulphurization,wet flue gas desulphurization(WFGD) was carried out in order to improve performances.The continuous gas phase has been modeled in an Eulerian framework,while the dispersed liquid phase with a Lagranian approaches.Through the method,the velocity and the change of pressure and temperature have been got.At the same time,the weighted average of mole fraction of SO_2 in different surface was analyzed for the angles of gas inlet.The results show that 10 degree angle of gas inlet should be chosen.
