Abstract
Determination of the actual size of the particles of dust emission building industry and construction
Incoming article date: 19.04.2015This article describes a way of reducing dust emissions of pollutions exhausted in the atmosphere in the manufacture of expanded clay aggregates and building construction industry, production of building materials using high effective dust cleaners. There described a promising approach to determining the actual size of the particles of dust emission building industry and construction in this article. It was proposed a common generalized approach to determine the actual effective or hydraulic sized dust particles. It could be done based on the on the results of analysis of variance (ANOVA) for expanded clay dust and bulk building construction materials. The development of new dust collectors with a high degree of separation, as a method to reduce dust emissions decreasing dust separation systems of aspiration scheme in the production of construction materials exhausted in the atmosphere. It was shown so that the hydraulic size of dust particles should be taken into consideration for design and account of dust separation devices. It was disclosed a practical method of estimating the effective value of horizontal cross-sectional area of projection of the dust particles. There presented one of the ways for numerical determination of hydraulic equivalent of particle size particle’s size in this paper. The results of this research should be considered when developing new designs of highly effective precipitators using ANOVA results of captured dust.
