Experimental Analysis of Controlling Pollutants by the Convergent Jet Air Curtain
In order to solve the problem of ventilation systems and pollution control systems where exist pollutants, taking into account the traditional sealed enclosures or partial enclosures, and other pollutants in exhaust hood to control the collection rate is very low. As the collection rate of the Traditional closed cover and local cover which control pollutants is poor, besides that, the energy consumption is Large, based on The actual needs of field and laboratory, the Prototypes and experimental models of Convergent air curtain generator have been set up. And with them univariate and multivariate orthogonal experiments have also been made. Through a large number of experimental analyses, the most Optimal parameters has been got, and the Theoretical model of Convergent jet air curtain. Based on the experimental and theoretical analysis, with the Case studies and Under the conditions of heat radiation of the convergent flow air curtain jet, Comparing with the static test, it has been found that Convergent air curtain makes the room temperature, dust and pollutant concentration, the concentration of air pollutants and energy consumption have been greatly reduced. The theoretical model and experimental results has some reference value and significance on environmental protection, labor protection and health protection related to protection design.
