In this paper, by applying air-curtain dust-controlling technique, a new fan, the air-curtain dust-controlling fan, is introduced, and has been manufactured. And its structure and application are described. Simultaneously, the theory of short-circuit flow field is put forward. Based on the principle of flow field superimposition, a mathematical model is established for the flow field. A new and highly...
In order to take effective dust removal measurement of transfer point of a coal preparation plant, it is necessary to put forward the optimal dust removal scheme. Production workmanship and dust pollution mechanism of the transfer point in a typical coal preparation plant has been analyzed. Based on the analyses, two feasible dust removal schemes of transfer point, namely the guide-chute dust removal...
