设计并试验了一种低温吸附压力恢复系统组合换热器,它由列管换热器和翅片管换热器组成,用来冷却负压高温高速激光器尾气,实现了尾气大温降、小压损。使用皮托排测量尾气平均总压,使用总温排和能量守恒法测量尾气平均总温,得到了准确可信的气流参数,为换热器优化设计提供了必要的依据。 A low temperature adsorption pressure recovery system combined heat exchanger is designed and tested. It consists of a tube heat exchanger and a finned tube heat exchanger, which is used to cool the exhaust gas at high temperature and high speed, and achieve large temperature drop of the exhaust gas. Pressure loss. The average total pressure of the tail gas is measured by Pitot line. The average total temperature of the tail gas is measured by the total temperature and energy conservation method. The accurate and reliable airflow parameters are obtained, which provides the necessary basis for the optimal design of the heat exchanger.
