Abstract
High efficiency of intensive work of wet scrubbers is the result of simultaneous formation of different collectors - dust collectors. Under the collectors it can understand the drops of the sprayed liquid, the bubbles generated in the conditions of intense bubbling, the liquid surface and the wet surface. All collectors are formed during the operation of the circulation unit, the features of which were considered in a previous article by the same authors. This article discusses the laboratory installation to assess the impact of various factors on the efficiency of collectors. The first device consists of three chambers in which the dust separation with a varying concentration of the suspension was analyzed independently in the drop area, under bubbling conditions, as well as upon impact on the wetted surface. To estimate the fractional effectiveness a multi-stage cascade impact mechanisms was used. A significant part of the second test bench was the dust collecting chamber, which provides a cross-flow of the suspension with respect to the dust gas acting on the surface of the liquid. A number of general efficiency tests were carried out at the stand under varying conditions of the impact of the outflow of dusty air on the surface of the liquid with constant dust dosing into the system. Dust removal efficiency was evaluated by measuring the mass of dust supplied to the system compared to the dust held by the filter on the outflow pipeline. The physical model of the phenomenon was developed on the basis of the hypothesis that the efficiency of dust particles capture by wet scrubbers depends on the absorption capacity of the liquid and, therefore, is associated with the concentration of the suspension. A high concentration of a suspension may prevent the penetration of particles in the reservoirs and not disclose them to the surface for further collisions of the dust particles.
