Study On The Application Of Two Stage Liquid Gas Jet Devices For The Mixing Reaction Technique

Based on the theory of two phase flow mass transfer and liquid-gas jet pump, the two stage liquid-gas jet mixing reaction device has been developed and applied in Guangxiwuzhou 1500 ton/year linalool plant and Tangshan steel company 1,300,000 ton/year coking enlarge plant. Through industry testing and analyzing, the design method has been improved. The basic to improving the efficiency of mass transfer and extending the application of this jet device is founded.In chapter 1, the history of the development and the application about the liquid-gas jet device is summarized. The purpose and significance of the research work is provided. The difficulty and the innovation of the research work are indicated. In chapter 2, the theory of liquid gas flow and liquid-gas jet pump has been analyzed systematically. In chapter 3, the process of developing the two stage circulating jet oxidation reactor is introduced. According to the; theory on chapter 2, the design method and calculation program is provided. The problem of the liquid-gas jet pump calculation for changing viscosity and density is solved. In chapter 4, the development of two stage liquid-gas jet pump for coal gas wetting desulfuration technology is presented, in which the air quantity is big and the air bladder is tiny. The calculation program of this jet device has been initially validated by the industry testing. In chapter 5, the research work is summarized and the expectation of this jet device application in industry is presented.
