Optimization of Slurry Mixing Performance Based on Parameters of Diffusion Chamber Using Response Surface Method
There is relatively little research on the influence of the diffusion chamber structure on the gas con-tent in the slurry mixing circulation system and the"cement emission"phenomenon of the slurry mixing tank.In order to clarify the influence of the diffusion chamber structure on the gas content in the recirculating system of ce-menting and the cement emission out of the tank deck,combined with the simulation analysis method,the re-sponse surface method was used to study the responses of H1(height of diffusion chamber outlet to liquid level),H2(height of mixer outlet to liquid level),v1(recirculation velocity)and A1(mixer inlet angle)to R1(gas con-tent in circulating medium)and R2(gas discharge out of tank deck).The study results show that v1 has the most significant influence on R1 and R2,while the influences of H1,H2 and A1 are different to some extent.The fitting functions of response constructed based on response surface method has high fitting accuracy and meets the design requirements.The optimization scheme obtained using optimization model within a limited range shows a 68%re-duction in the gas content of circulating medium and a 71.4%reduction in the gas discharge out of tank deck com-pared to the original scheme.This method provides certain technical reference for the design of diffusion chambers.
