| Abstract: | Based on the mixture model and CFD numerical simulation,the effects of the decanter on the separation process of coal gasification ash water are studied by drum speed,handling capacity and differential speed.The results show that the solid content rate of the discharge slag increases rapidly with the increase of the rotating drum speed.After the rotating drum speed reaching 2000r/min,the solid content of the discharge slag increases slowly with the rotating drum speed continuing to increase;The solid content rate of the discharge slag does not change significantly with the increase of the handling capacity,but it decreases with the continuous increase of the handling capacity after 50.75m3/h;The difference of rotation speed between rotor drum and screw pusher has no obvious effect on the separation performance of the decanter.The field separation test of gasification. |
