一、问题的提出在气固分离的各种装置中,旋风分离器是应用比较广泛的一种,随着旋风分离技术的发展和各种型式的旋风器相继问世,促进了对旋风器内气固分离机理的研究。许多学者曾对旋风器的流场做过测试,对气固分离机理也曾提出过多种模型和解释。近年来,用二相流理论所进行的研究,已引起了广泛的重视。但是,迄今为止,人们对旋风器的了解还很不完善,各种理论见解和实验结果差距较大,甚至相互矛盾,以致于至今旋风器的设计仍依赖于经验和大量的工业试验。因此,对于旋风器的研究,尤
First, the issue put forward In the gas-solid separation of various devices, the cyclone is a more widely used, with the cyclone separation technology and the development of various types of cyclone have been promoted to promote the cyclone gas Study on Solid Separation Mechanism. Many scholars have tested the flow field of the cyclone and have proposed many models and explanations on the gas-solid separation mechanism. In recent years, research using two-phase flow theory has drawn wide attention. However, to date, people’s understanding of the cyclone is still far from perfect. The theoretical opinions and experimental results are far behind or even contradictory to each other, so far the design of the cyclone still depends on experience and a large number of industrial experiments. Therefore, the study of the cyclone, especially
