摘要

建立了喷射式低温乏汽回收利用装置的火用分析模型.对比研究了无旋流、水旋流、蒸汽旋流、水汽旋流4种结构形式下装置火用效率的变化规律

分析了喉嘴距、混合腔收缩角、喉嘴面积比等结构参数对装置火用效率的影响

研究了水旋流形式下装置火用效率随汽水参数变化的规律.发现最佳的结构形式为水旋流结构

最佳的结构参数为:喉嘴距L=145 mm、收缩角θ=18°、面积比M=5.44

得出装置火用效率随进水温度和进汽压力的增加而增加

随进水压力的增加而降低.研究结果可为装置结构的优化和运行参数的选择提供依据.

Abstract

An exergy analysis model of an exhaust steam reclaim device with injector was established. The variation of exergy efficiency was compared under four different structures(without-swirling

water-swirling

steam-swirling and steam-water-swirling)on the basis of the experiment. The influences of the different structure parameters(spout-throat distance

contract angle and area ratio)of the injector and different steam-water parameters on the exergy efficiency of the device were analyzed. The results show that the adoption of the water-swirling structure can obtain the optimum exergy efficiency. Moreover

the exergy efficiency reaches the highest value at the spout-throat distance of 145 mm

the contract angle of 18°

and the area ratio of 5.44. In addition

the exergy efficiency of the injector increases with the increase in the inlet water temperature and the inlet steam pressure and decreases with the increase in the inlet water pressure.
