STUDYING AND APPLYING THE EFFECTION OF WHIRLING AIR STREAM ESTABLISHING CENTRIPETAL WET-FILTER PRINCIPLE

Abstract

Filtration is a process which removes Posion gas and Dust from polluted air jet with many different methods. In practice, One normally combines Wet Scrubber with another equiment such as: Cyclon, buffer tower, Ventury equiment... This method has some advantages:  Wet scrubber is easy to manufacture, lower price but high efficent.  This equiment can remove dust which is 0.1 u.  It is able work under hot temperature & moiture condition in which the others cannot satisfy. This equiment filters not only dust but also posionous gas. Howerver, when this filter is applied in Vietnam, some phenomenons occur:  It sometimes works unstable, unefficeni.  The essence of gas jet is that it usually contains variety of dust & toxicant in hot & changing condition so that it is likely to be stucked. Wet cyclon appoarch studied on pratical models which are similar with realities base on the effects of whirling air which combine with vaseline to create tiny & thick density water drop for increasing its feasibility. The result puts forward a new princible of wet scrubber different with the other. The equiment made from this princible is more economy and more out put, easy & stable to operate.
