摘要
楼房猪舍可充分利用土地资源,具有提高单位面积生产效率与减少环境污染面积等优点,但同时由于楼房猪舍中不同楼层不同猪舍的环境要求不同,导致不同猪舍内环境难以精准控制。为了研究楼房猪舍环境精准控制方案,基于计算流体力学(CFD),采用ANSYS FLUENT软件优化改进楼房猪舍气流场分布。设计基于标准k-ε湍流模型模拟楼房猪舍气流场,在此基础上调整和优化猪舍内通风口位置,结果显示,优化后的设计方案可使猪舍内气流场更加均匀,避免同一猪舍内环境偏差较大。最后,基于优化后的设计方案,利用PLC对楼房猪舍内环境的精准控制进行了设计和实现。
Multistory pig building could make full use of land resources,and had the advantages of improving production efficiency per unit area and reducing environmental pollution area.However,due to the different environmental requirements of different floors in the multistory pig building,it was difficult to accurately control the environment in the multistory pig building.In order to study the pre⁃cise control scheme of multistory pig building environment,ANSYS FLUENT software was used to optimize and improve the airflow field distribution of multistory pig building based on computational fluid dynamics(CFD).Based on the standard k-εturbulence mod⁃el,the airflow field in the multistory pig building was simulated,and the ventilation position in the piggery was adjusted and opti⁃mized.The results showed that the optimized design scheme could make the airflow field in the piggery more uniform and avoid large environmental deviation in the same piggery.Finally,based on the optimized design scheme,PLC was used to design and realize the precise control of the environment in the multistory pig building.
