Determination of Settling Efficiency of Solid Finely Dispersed Particles Within Devices with Rectangular Separators

摘要

Design of dust-collecting device, characterized by low hydraulic resistance and high efficiency of collecting the fine particles, has been developed. It has a simple construction. It lacks small parts and small channels, which increases the reliability of its operation. It can be disassembled and restored. Separators are using for solid particles and droplets capturing from gas flow by means of gravity, inertia of centrifugal force. They can be used in industrial vacuum cleaners and can allow increasing the cleaning efficiency. The influence of design and technological parameters on collecting efficiency has been researched. The availability of several rows of separators leads to an increase in the settling efficiency of solid dispersed particles due to a more ordered structure of the gas flow. The studies of the influence of the geometrical constant of the proposed device on the settling efficiency show that in order to collect the relatively large particles, the dimensions of settling elements should be increased up to 50 mm.
