离心脱盐集渣一体机设计与性能研究
Design and performance research of centrifugal desalination and slag collection integrated equipment
摘要
Abstract
In view of the characteristics of high salinity of suspended particles in the tail water discharged from high-density intensive aquaculture,and the low efficiency and high cost of traditional tail water treatment equipment,this study designed a centrifugal desalting and slag collection machine integrating centrifugal dehydration,high-pressure spraying and negative-pressure collection,completed the structural design and control system of the equipment,and made a prototype to carry out performance tests.The raw water mixed with feed and seawater is used to simulate the actual tail water,and the collection rate,desalination rate and water content of treated solid particles of the equipment are taken as indicators.By using the single factor experimental design method,the performance test is carried out under the working conditions of the same equipment operating parameters and different liquid-solid concentration ratios,and the treated solid particles are dried to calculate the index value of the equipment.The results show that the equipment has a good effect of solid-liquid separation and salt reduction.The collection rate of solid particles in aquaculture tail water can reach over 60％,the desalination rate is over 80％,and the water content of treated solid particles is about 65％.The research shows that the equipment can significantly reduce the pollution risk of water and soil caused by direct discharge of tail water,and realize the resource utilization of tail water tailings,which has a good prospect of popularization and application.关键词
