摘要
液包式雾化喷嘴是一种新型脱硫雾化喷嘴,其出口锥角直接影响其雾化性能。采用图3所示实验台架,选用喷嘴出口锥角开展实验,并利用Winner318型激光粒径分析仪,进行了雾化特性试验。结果表明,内锥角的变化对雾化角的影响明显,而外锥角的变化对雾化角基本无影响;内、外锥角的改变对平均雾化粒径基本无影响,喷嘴的雾化角和平均雾化粒径随着气液压力比的增大而减小,当气液压力比达到1.5后,气液压力比的影响作用降低。
The liquid bag type atomization nozzle represents a novel type desulfurization atomization nozzle and its outlet cone angle directly affects the atomization performance.The test rig as shown in Fig.3 was used and a nozzle with a cone angle at the outlet was chosen to conduct a test.The atomization characteristics were tested by using a Winner 318 type laser particle diameter analyzer.The test results show that a change of the inner cone angle conspicuously affects the atomization angle while a change of the outer cone angle basically does not influence the atomization angle.A change of the inner and outer cone angle basically has no influence on the mean atomization particle diameter.Both atomization angle and mean atomization particle diameter of the nozzle will decrease with an increase of the gas/liquid pressure ratio.After the gas/liquid pressure ratio has reached 1.5,the influence of the gas/liquid pressure ratio will become smaller.
