Research progress of foam dedusting technology in coal mining
To solve the problem of coal dust in coal mining,the development of surfactant,the optimization of parameters and the design of equipment in foam dedusting technology were studied.The influence of particle size on capture efficiency is discussed.The relation-ship between the composition and performance of surfactants was analyzed.The advantages and disadvantages of different foaming de-vices are compared.The concentric tube foam generator has high dust removal efficiency,good system stability and reliability.Studies show the dust removal efficiency of foam dust remover is mostly 80％～90％,and the removal efficiency of total dust is higher than that of inhalable dust.There is still space for the development of surfactants and the structural design of foaming device.
