Abstract

Cyclonic duster has become the mainstream in fully mechanized workface, better than any other kinds of dusters in dust removal efficiency, sewage discharge, disassembly and assembly, moving with the boring machine etc. This paper reveals the effect that the opening of the throttle plate significantly affects the water jet by Bernoulli equation, and the parameters related to the vibration effect by the vibration frequency formula, and also states that when the centrifugal force and the air resistance are in balance, dust particles began settling on the cavity. Wet dust removal technology has developed rapidly over the last two to three decades and become mainstream technology in coal mine production. There are lots of papers focusing on dusting efficiency influenced by changing parameters, such as nozzle types, structure parameters, wind speed and ventilation volume. This paper summarizes characteristics related to mechanisms of wet dusting and dust capturing. It also outlines the research advance of mine wet duster and analyzes the existing problems. The paper focuses on the mechanisms of three types of wet duster in fully mechanized workface. The research and application of future are also prospected.
