Electrostatic separation of particles used as complement to mechanical recycling plant of industrial waste
This paper concerns the implementation of the electrostatic separation process as complement of the mechanical sorting separators in the recycling industry. Preliminary experiments carried out on the laboratory separator have established the limit values for the speed of the rotating electrode and the high supply voltage for the industrial prototype. Industrial tests have validated the use of electrostatic separation as a complement to the other …
Experimental analysis of micronized plastic particle movement on electrodynamic screens
The electrical curtain board (ECB) is constituted of parallel linear electrodes deposited on a dielectric layer plate and supplied by a poly-phase electrical voltage. This paper reports a study of the movement of Polyvinyl Chloride (PVC) μm-size particles on such an ECB. The experimental setup comprised three ECB plates of different inter-electrodes spacing, and a homemade electric supply. Obtained results show that it is possible to move the qua…
Experimental and numerical analysis of a tribo-electrostatic separation process of micronized plastic particles using rotating disk electrodes
This paper reports an experimental and numerical analysis of a tribo-electrostatic separation process based on a fluidised bed tribo-charging system and two rotating disks connected to two high-voltage DC supplies of opposite polarities. The experiments were performed using a granular mixture composed of μm-size white Polyvinylchloride particles (WPVC) and grey Polyvinylchloride particles that contain a small percentage of carbon (GPVC). A numeri…
Experimental analysis of a corona-charged baghouse filter
This paper describes an experimental investigation of a modified baghouse filter (BHF) configuration for enhancing the collection efficiency of a medium filter. Most baghouses use cylindrical woven or non-woven filter bags as a filter medium. Particles are captured on the filter, and the clean gas escapes. A modified configuration of the BHF is proposed, and the proposed configuration was experimentally tested. The medium filter was electrically …
Experimental analysis of the influence of the voltage waveform on ozone generation efficiency
Although the dielectric barrier discharge (DBD) has been widely considered and studied for ozone generation, only a few studies have examined the influence of the alternating voltage waveform on the ozone rate production. This paper analyses the influence of the voltage shape on the ozone concentration and the energy efficiency of a DBD cylindrical ozone generator. Three voltage signals were studied using a high-voltage amplifier: sinusoidal, tri…
Particle distribution analysis along the collection electrode of a ‘wire-to-cylinder’ electrostatic precipitator
This study determined the value distribution of the ‘charge/mass’ ratio of the particles charged by corona along a ‘wire-cylinder’ electrostatic precipitator (ESP). These particles are absorbed by suction from the openings on the collection electrode. The results enabled the analysis of the particle movement in the ESP. For moderate voltage values (8–12 kV), the constant ratio along the ESP suggests that the product is uniformly collected when th…
Experimental analysis of a novel ozone generator configuration for use in water treatment applications
Volume dielectric barrier discharge (VDBD) is considered to be the most effective method for ozone generation. This paper reports a comparison between a simple ‘classic’ VDBD cylindrical ozone generator and a ‘metallic-mesh-filled-air-gap cylindrical dielectric barrier discharge’ model. The obtained results show that although the majority of ozone generators are of the volume discharge type, the novel volume discharge model has provided better re…
New separation method of metal/plastic micronized particles using travelling wave conveyors
The paper reports an experimental investigation for studying the movement dynamics and the separation of micronized particles on a poly-phase travelling wave conveyor (TWC). A digital balance and a sensitive electrometer controlled by Labview software were used to analyse the velocity and the material flow rate on a three-phase conveyor with respect to the variation of both the amplitude and the frequency of the applied voltage. It was found that…
Determination and analysis of the electrical components of a PEF treated equivalent circuit of potato tissue
The permeabilized membrane state of a pulsed electric field (PEF) treated biological sample is invisible to the naked eye, but can be deduced as the permeabilization causes loss of the insulating properties of the membrane, which can be determined by measuring the electrical impedance. This paper reports a spectroscopic analysis of a PEF treated and untreated potato sample to determine the electrical components of the biological tissue equivalent…
Design and development of a low cost technique for sorting household wastes using eddy current separation process
Recovery and recycling of metals from wastes have a major role in the global economy because of the scarcity of raw materials and the problem of environmental pollution. This paper reports a technical and economic study for the development of a low-cost eddy-current separator for household waste treatment. Waste treatment in African countries suffers a developmental delay owing to the cost of such equipment. On the basis of preliminary results ob…
Experimental investigation of a PV solar generator for supplying water treatment process
The paper describes a photovoltaic solar generator to supply a dielectric barrier discharge ozone generator employed for water treatment. This paper reports trials of the equipment and modelling the solar power generation system's efficiency. The design methodology was used to obtain the optimal set point for the orientation of the solar panel during the passage of clouds which causes the decrease of sunlight and thus reduced ozone production. In…
Robustness testing of the juice extraction process using a pulsed electrical field
As robustness of any industrial process is an important issue, a standard procedure is used to determine the set point and to minimize the process variability of juice extraction to changes in values of some critical factors. This paper reports work to analyse the efficiency of the pulsed electrical fields carrot juice extraction process even when the control factors undergo slight random variation. The experiments were carried out on a laborator…
Set‐point identification of a free‐fall triboelectrostatic separation process for plastic particles
Identification of the optimal operating conditions and evaluation of their sensibility to changes in certain critical factors are critical issues for the industrial application of electrostatic separation techniques. The aim of this paper is to validate an experimental procedure for optimising the selective sorting of non‐conductive constituents of granular industrial plastic wastes using a free‐fall triboelectrostatic separator
Plastic wastes recovery using free‐fall triboelectric separator
Among the separation techniques used in industry, the triboelectric separation of insulating particles using rotary tube is an efficient technology employed in waste recovery and mineral industries. This process, also called free‐fall triboelectric separation, is widely used for the sorting and the purification of granular materials resulting from industrial plastic wastes. This paper offers a comprehensive description of a laboratory triboelectr…
