Experiment and Research on the Mechanism of Foam Dedusting Agent
This paper explains how to solve the problem that the foam dedusting agent is not able to dedust efficiently according to its low foaming rate and poor wettability and finally obtains an optimal formula of foam dedusting agent. We first studied the mechanism of foam dedusting and learned that the process of foam-dedusting is comprised of interception, adhesion, wetting, and sedimentation. Then the optimal formula named Foam Dedusting Agent CNSD-1 were obtained, which is comprised of Sodium Dodecyl sulfate being foaming agent, Soluble starch being foam stabilizer, Dioctyl sodium sulfosuccinate being wetting agent, by an advanced ROSS-Miles experiment and contact angle measurement. The mass concentration of the three kind of powders respectively are 0.5%, 0.06% and 0.3%. Through the field application the conclusion can be draw that the total coal dust dedusting percentage of it is 96.35% and the respiratory coal dust dedusting percentage of it is 86.08%, the Effect is remarkable.
