Due to the turbulent mixing between agglomeration agent and dust, number of collisions per unit time particles droplets increases with particle size in process chemical agglomeration, efficiency accordingly. Turbulent can promote effect subsequent by strengthening collision agglomerant droplets. The author used cooperate order improve dust removal. from removal efficiency, which greatly electri...

The separation of particles from gases within electrostatic precipitators is mainly depending on the flow conditions. The flow field is governed by the mutual interaction of the electric field with the gas ions and the turbulent channel flow. Especially for wire-plate electrostatic precipitators this causes secondary flows, well known as the 'ionic wind'. The influence of the ionic wind on the ...

Co2Nx/nitrogen-doped reduced graphene oxide (Co2Nx/NG) is synthesized by electrostatic co-precipitation of Co and rGO followed by high-temperature nitridation, which can serve as an efficient catalyst for sensitive glucose detection due to the unique electrocatalytic property of Co2Nx and synergistic effect between Co2Nx and N-doped rGO.

Small molecular reagents that can efficiently functionalize water soluble CdSe/ZnS nanocrystals (NCs) are reported. These reagents do not cause quenching or precipitation of NCs as seen with commercially available activators. The results demonstrate that controlling the electrostatic character of the materials is critical in the design of functionalization schemes.

The impact of electrostatic precipitation as a useful form of particulate filtration in the breathing zone is investigated in an intervention study in an air-conditioned commercial office in central London. Surface dust deposition and airborne dust levels are measured in the open plan zones of two floors--a control floor and a floor where the intervention is effected. The intervention consists ...

Small particles are of great interest in a variety applications. Spray drying is common technique for particle synthesis, but it limited with respect to sizes below 10 μm. Therefore, new laboratory-scale spray dryer was designed address this issue. A novel aerosol generator consisting piezo crystal swirl chamber obtain droplets the low micrometer range. After and cooling, were deposited molten ...

In this work, the development of a point-of-care (PoC) system to capture aerosol from litres of air directly onto a microfluidic lab-on-chip for subsequent analysis is addressed. The system involves an electrostatic precipitator that uses corona charging and electrophoretic transport to capture aerosol droplets onto a microfluidic air-to-liquid interface for downstream analysis. A theoretical s...

the electrohydrodynamic (EHD) flow in a relatively wide electrostatic precipitator (ESP) (width:height = 2) is 2-or 3-dimensional (3D). The previous our measurements of 3D time-averaged flow velocity fields suggested that the flow in the ESP duct centre is almost 2-dimensional. In this paper we present both the 3D instantaneous and time-averaged flow velocity fields in a relatively wide ESP (wi...
