High field strengths lead to a significant increase of the adhesive force. Here, more insight into the underlying mechanisms is given by experiments on the microscopic scale. An experimental arrangement is described which allows to study a particle pair subject to a strong electric field. Both the current and the force between the particles (150 μm) can be measured as a function of voltage and gap distance. The results show an extremely complex behaviour of the contact for the case of highly resistive particles. For current transport, both gas discharges and thermionic field emission are observed, depending on the width of the contact gap and the field strength. For both the force and the current across the gap, a strongly non-linear behaviour with pronounced time effects is observed.

Being the first study case, this work is focused on the influence of electrostatic fields and space charge on the velocity field inside a wire-plate Electrostatic Precipitator (ESP) with one-way-coupling dynamics. The study case is an attempt to replicate velocity profiles and Turbulent Kinetic Energy (TKE) budgets obtained in the Direct Numerical Simulation (DNS) carried out by Soldati and Banerjee (1998). Qualitative trends are confirmed in preliminary ODT results, thus showing the potential of the stochastic ODT modeling approach for other types of EHD flows.

Industriebeispiel HKM Duisburg T2 - Jahrestreffen der ProcessNet-Fachgruppen Mechanische Flüssigkeitsabtrennung und Gasreinigung, 14.-15. März 2019, Bamberg N2 - Elektroabscheider bewähren sich in Rauchgasreinigung als sehr robust und zuverlässig. Allerdings werden zahlreiche und nicht immer genau bekannte Parameter für eine sichere Auslegung von Elektroabscheidern benötigt. Eine nachträgliche Veränderung der Betriebsparameter kann zur Minderung der Zuverlässigkeit eines Elektroabscheiders führen. Das Rauchgas aus dem Stahlkonverter (HKM, Duisburg) wird in einem Nass-elektroabscheider von Partikeln befreit. Als HV-Elektroden kommen sog. „high emission electrodes“ zum Einsatz. Diese weisen eine sehr geringe Corona-Einsatz-spannung auf und erschöpfen die Leistungsreserven des HV-Trafos bereits bei mittleren Spannungen. Eine weitere Erhöhung der Spannung ist aufgrund der Strombegrenzung nicht möglich. Eine zweistufige auf das Aerosol abgestimmte HV-Elektrode wird entwickelt und im Technikums-Maßstab ausprobiert. Diese ermöglicht eine äußerst effiziente Nutzung des Corona-Stromes. Die Aufladung von Partikeln erfolgt damit fast ausschließlich im gequenchten Bereich, in dem die Gasionen ihre Ladung fast vollständig auf die Aerosolpartikeln übertragen. Eine deutlich höhere Betriebsspannung kann erreicht werden. Eine originale HKM Elektrode wird einer optimierten im Technikumsversuch gegenübergestellt. Der Betriebspunkt (Spannung und Strom) des HKM Elektro-abscheiders wird durch die Veränderung der Aerosol-Anzahlkonzentration und Größenverteilung nachgebildet. Abscheideleistungen bei einer typischen Betriebs-spannung sowie bei der maximalen Trafo-Leistung von 205 W pro Abscheiderohr werden erfasst. Die Versuche werden durch eigene Simulationsrechnungen unterstützt. Die Simulationsergebnisse stimmen mit den Messergebnissen sehr gut überein. Die optimierte Elektrode bringt folgende Vorteile gegenüber der originalen Elektrode: a) 2/3 der Energie werden bei einer gleichen Abscheidung eingespart. b) 9-fache Verbesserung der Abscheidung bei einem gleichen Energieeintrag. Eine technische Umsetzung der gewonnenen Kenntnisse steht in Aussicht. Y1 - 2019 UR - https://dechema.converia.de/frontend/index.php?page_id=6528 ER - TY - GEN A1 - Bürger, Patrick A1 - Riebel, Ulrich T1 - Characterization of flame-generated SiO2 aerosols and their utilization in research of high temperature electrostatic precipitation: A project outlook T2 - Jahrestreffen der ProcessNet-Fachgruppe Gasreinigung und des TAK Aerosoltechnik N2 - Gas-phase particle separation at significantly elevated temperatures is a scope since heat recovery units might be operated with higher efficiency and lower maintenance costs when fouling by particulate deposits could be reduced. However, this proves difficult for most separation techniques for numerous reasons (particle size limitations, material limitations, pressure difference limitations). While the upper temperature limit for standard electrostatic precipitators (ESP) operated at ambient pressure and with negative polarity is around 400°C, positive polarity theoretically should allow an operation with temperatures well above 600°C. However, there seems to be very little experience with high temperature ESPs even on the lab scale or small pilot scale. To close this apparent gap in electrostatic precipitation research our current project aims to investigate the characteristics of a SiO2 aerosol and the capabilities of an ESP dealing with said SiO2 aerosol at 600°C and above. The aerosol is produced by combustion of silicone oil (HMDSO) in a propane flame which leads to particle size distributions ranging from below 10 nm up to 400 nm. The median value of the distribution and the total number concentration is a function of the gaseous HMDSO amount introduced into the flame. Increasing the HMDSO supply shifts the median to larger particle diameters but also reduces the total number concentration, which is an interesting phenomenon to be looked into in more detail during the project since coagulation cannot explain this on its own. The observed high number concentrations at low HMDSO feed rates may involve thermal rebound which needs further investigation. Additionally, the bipolar charge distribution typical for flame-generated aerosols has to be considered when deriving an explanation for the observations. The next steps will be a more detailed characterization of the produced SiO2 aerosol and the operation of a high temperature ESP in wire-tube geometry.

The critical dust layer thickness for the occurrence of back-corona may vary by several orders of magnitude depending on the specific dust resistivity, dust layer porosity, particle size, humidity and operating temperature. Despite the difficulties at elevated operating temperatures, processes involving highly resistive dusts (e.g. oxidic materials) may benefit significantly from utilizing high temperature ESPs (HT-ESPs). This is because the specific resistivity of materials like SiO2, Al2O3 and other oxides decreases below the critical value of 10^11 Ω*cm at higher temperatures. Currently, the separation of oxidic nanoparticle products relies on cloth filters which require exhaust gas quenching prior to dust removal. Using heat exchangers instead to recover excess heat is not feasible due to severe scale formation. Therefore, the development of a reliable HT-ESP would allow heat exchange at clean gas conditions reducing operating costs of the overall process. During preliminary experiments for our ongoing investigation of HT-ESPs, the behaviour of a flame-generated SiO2 aerosol was studied at 200°C in a wire-tube configuration. In order to reach a better understanding of the back-corona, measurements of the particle size distribution, particle charge distribution and electric current were conducted for both polarities. Strong effects are found even though the dust layer thickness is a few μm only. While the separation efficiency decreases rapidly after a critical dust layer thickness is reached, the current uptake increases significantly (up to a factor of 20), and a large number of inversely charged particles is found in the clean gas. These effects may indicate a large-scale back-corona. A detailed discussion will be given on the basis of aerosol size and mobility distributions, SEM images and resistivity measurements of the dust layer.

The experiments have shown that electronic charging of aerosols can be important in technical scale electrostatic precipitators (ESPs). Already at operation voltages just slightly above the corona onset voltage, the contribution of the free electrons to the overall current is estimated to be around 50 %. Due to the high temperature of free electrons, diffusion charging by free electrons allows to reach exceptionally high particle charge and extremely high precipitation efficiency. A strongly simplified theoretical model was developed, which gives a good prediction of particle charge based on averaged values of particle diameter, current density, electric field strength, electron temperature and residence time. The ion mobilities were determined by fitting the current-voltage characteristics with a modified Townsend (Monrolin et al. 2018) equation and are significantly higher than the values typically used to describe diffusion charging in air. This may be ascribed to the very dry gas phase and the short average lifespan of the ions under ESP conditions, which is in the order of 1 ms. From the practical point of view, electronic charging might be relevant in a number of technical applications, including high temperature ESPs, ESP applications in dry and oxygen-free gases and pulsed corona systems.

After a short review of the physical fundamentals it is explained why measurements of the pressure gradient play an important role in the design principles for this technology. Its external influence by operating parameters like voltage polarity and aerosol conditions will also be shown. In the second part, the feasibility of enhanced mass and heat transfer is demonstrated based on laboratory measurements. In combination with the previously discussed pressure gradient measurements, methods for simplified engineering concepts like equivalent mean flow velocities or turbulent diffusion coefficients are shown. The topic is rounded off by outlining a potential use in decentralized power generation.
