performance of a combined Cyclone Filter aerosol collector
Particulate Science and Technology, 2011Co-Authors: Mason Sangkhamanee, Perapong Tekasakul, Surajit Tekasakul, Yoshio OtaniAbstract:The collection efficiency of fine aerosol particles of a Cyclone collector was improved by combining the Cyclone with Filters. The effects of particle size and inlet velocity on the penetration and pressure drop were studied. Results show that the penetration of the Cyclone combined with a 4-mm and a 8-mm fibrous Filter for particle sizes between 0.3 to 1.0 μm was lower than that of the Cyclone up to about 20%. The penetration of the Cyclone combined with 0.94 and 1.83 g stainless steel Filter was found to be lower than that of the Cyclone up to about 41%. Moreover, the pressure drop of the Cyclone combined with a 4-mm and a 8-mm fibrous Filter width was 39.9 and 48.9%, respectively, lower. For a Cyclone combined with 0.94 and 1.83 g stainless steel, the pressure drop was 30.6 and 25.7%, respectively, lower. The improvement of the collection performance, a higher collection efficiency, and a lower pressure drop, is attributed to a change of the collection mechanism from centrifugal force to partial filtra...

Effect of a combined filtration system and drip irrigation laterals on quality of rainbow trout farm effluent
Irrigation Science, 2020Co-Authors: Naser Manbari, Eisa Maroufpoor, Younes Aminpour, Barzan Bahrami Kamangar, Jaume Puig BarguésAbstract:The main aim of this study was to investigate the qualitative changes of the rainbow trout effluent as water supply in a drip irrigation system. Two drip irrigation systems with a hydro-Cyclone Filter, sand Filter and screen Filter for using freshwater (control treatment) and fish farm effluent were tested in Kurdistan province (northwest of Iran) in 2017. In addition, the effect of lateral drainage at the end of each irrigation event was also studied. Two emitter types with different discharge flows were used for each treatment. In the 16 irrigation events carried out, samples were collected from the different water sources (dam, well, and river), Filter outlets and lateral locations for measuring total suspended solids (TSS), particle size, pH, electrical conductivity, different compounds (Fe, Na, K, Ca, Mg, NO_3, PO_4, HCO_3) and the number of coliform bacteria. The results showed changes in the TSS and the number of coliform bacteria, but the remaining parameters had slight changes. In both control and effluent treatments, the filtration system significantly reduced TSS, having the screen Filters the greatest effect on this decrease and hydro-Cyclone and sand Filter the least. To achieve higher removals, it is recommended to use finer grains in sand Filters. The filtration of both control and effluent treatments increased the number of bacteria. The highest number of bacteria in the control treatment was measured after the sand Filter and in the effluent treatments after the screen Filter.

Improving Energy and Environmental Efficiency of Flue Gas Cleaning at Thermal Power Plants
IOP Conference Series: Earth and Environmental Science, 2019Co-Authors: A.t. Zamalieva, M.g. ZiganshinAbstract:The aim of the work is to improve Cyclone and Filter dust collectors by increasing the efficiency of fine particle deposition classes PM10, PM2,5 as well as reducing energy and material costs. The analysis of existing methods of cyclonic filtration of industrial dispersed emissions is carried out. The laboratory tests of the Cyclone Filter, made by modernization of the Cyclone CN-11-200, were performed, the aerodynamic characteristics of its operation were found. The calculated determination of the efficiency of suspension deposition from multiphase flow in the separator using a dimensionless Re r criterion is performed, derived from the Navier-Stokes single-phase flow equations of motion and the particle motion equation based on Newton's law. A numerically studied the aerodynamic parameters of the Cyclone on the basis of computational fluid dynamics methods. For mathematical modeling of turbulence we used the DES model

Numerical and experimental studies of gas cleaning in multi-Cyclone elements with Filter inserts
IOP Conference Series: Materials Science and Engineering, 2019Co-Authors: G I Belyaeva, A.t. Zamalieva, M.g. ZiganshinAbstract:As a result of the tightening of standards for the content of suspended particles with a particle size of less than 10 μm in the atmospheric air, the development of production structures in the urban environment often becomes closely linked to the problem of deep cleaning of heterogeneous emissions, that requires, at a minimum, two-stage cleaning. In this paper, we consider the effectiveness of using a multi-Cyclone apparatus for such purposes, the elements of which combine both stages of purification. A bench test of such an element, which is a Cyclone Filter with a diameter of 250 mm on the basis of a serial Cyclone TsN-11, was carried out. A numerical model of the multi-Cyclone has been investigated, which has made it possible to establish the optimal arrangement of the Cyclone elements with respect to the trajectories of the streams of trapped particles.

Numerical study on pressure drop and filtration efficiency of gas–solid flow through axial Cyclone separators
International Journal of Advances in Engineering Sciences and Applied Mathematics, 2020Co-Authors: B. Gopalakrishnan, K. Arul PrakashAbstract:The separation of particulate matter from incoming gas flow is necessary for different industrial applications, and this filtration process is primarily done by Cyclone separators. In axial inlet Cyclone separators, a swirling motion is imparted to the incoming flow by means of a swirl generator and particle separation is achieved by centrifugal separation. In this paper, the gas-particle flow through an axial inlet Cyclone separator is analysed by the Eulerian–Lagrangian CFD approach using the open-source package OpenFOAM. The turbulent flow field is modelled using Reynolds-averaged Navier–Stokes equations with RNG k – ε model, and the particle trajectory is calculated by discrete phase modelling. The study mainly focuses on the modelling and simulation of the dispersed flow, the development of the turbulent flow field inside the Cyclone Filter and the influence of the solid phase on the flow field. The simulation results show that the solver effectively models the flow field and the centrifugal separation of particles. The analysis of particle trajectory and the effect of particle density on the flow with both uniform and varying inlet particle distribution are also discussed.
