Experimental study on aggregation of oily fine particles undercombined action of acoustic waves and water vapor
摘要：
为了分析厂房内生产过程中油性细颗粒物的聚并效率,并探讨聚并过程中的影响因素,本文建立了声-水汽联合作用下的油性细颗粒物聚并长大实验台。实验结果表明:在冷凝室温度10～20 ℃区间内,随着温度的降低,油性细颗粒物的聚并效率逐渐提升;在实验范围内,声强强度小的声波更有利于小粒径油性细颗粒物的聚并,并且小粒径颗粒物在声聚并下的聚并效果优于大粒径颗粒物。
Abstract：
To analyse the aggregation efficiency of oily fine particles during production in industrial workshops, and to explore the influencing factors in the aggregation process,this paper establishes an experimental bench for the aggregation and growth of oily fine particles under the combined action of acoustic waves and water vapor. The experimental results show that within the temperature range of 10 ℃ to 20 ℃ in the condensation chamber, the aggregation and removal efficiency of oily fine particles gradually increases as the temperature decreases. Within the experimental scope, acoustic waves with lower intensity are more conducive to the aggregation of smaller-sized oily fine particles, and the aggregation effect of smaller particles under acoustic aggregation is superior to that of larger particles.
