摘要

针对不同的喉嘴距、面积比

实验研究了不同的进水压力、进水温度和出水压力对低温乏汽回收利用装置性能的影响规律.发现在进水压力为0.14～0.50 MPa、进水温度为23～60 ℃、出水压力为0.096～0.110 MPa

以及4种喉嘴距、3种面积比的实验条件范围内

随着喉嘴距和面积比的增加

加热温升和流量比先增大后减小

得到最佳归一化喉嘴距L=4.50

以及最佳面积比m=6.25

使得加热温升和流量比最大.同时

加热温升和流量比均随着进水压力和进水温度的增加而减小

当出水压力升高时

装置性能变差

加热温升和流量比均减小.

Abstract

An experiment on the performance of water-driven jet steam ejectors with three area ratios and four distances between the throat and the spout was conducted at the inlet water pressure of 0.14-0.50 MPa

the temperature of 23-60 ℃

and the outlet water pressure of 0.096-0.110 MPa. The results show that the temperature rise and the flux ratio increased first and then decreased with the increase of the area ratio and the distance between the throat and the spout. The values of the temperature rise and the flux ratio would be maximum when the area ratio equaled 6.25 and the dimensionless distance between the throat and the spout was 4.50. In addition

the temperature rise and the flux ratio decreased with the increase of the inlet water pressure

the inlet water temperature

and the outlet pressure

respectively.
