Influence of pollution of the arcuate separator elements on the gas flow structure
Keywords:
separator, cyclone, fine particles, dust, gas purificationAbstract
The paper presents a model of a separator for cleaning a dusty gas flow from fine particles. This device is proposed to be installed as a second cleaning stage after cyclones. Thus, at first the gas flow will be effectively cleaned from dust particles larger than 10 μm by a cyclone, after which the gas flow will be cleaned from particles smaller than 10 μm by a separator. Purification of the dusty flow from small particles in the separator is carried out due to the action of centrifugal forces on the gas flow. As the arcuate elements become clogged with fine dust, the hydraulic resistance of the separator decreases, which is a positive factor contributing to the reduction of energy costs at the enterprise. As a result of the experimental study, it was revealed that as the arc-shaped elements are clogged with fine dust, the hydraulic resistance of the separator decreases, which is a positive factor contributing to the reduction of energy costs at the enterprise. The decrease in hydraulic resistance is due to the exclusion of reverse flows of the gas flow in the separator. The main parameters affecting the energy efficiency of the separator is the degree of clogging of arcuate elements, the inlet velocity of the gas flow and the efficiency of gas flow purification
