Coaxial (wire-cylinder) electrodes arrangements are widely used for electrostatic deposition of dust particles in flue gases, when a high voltage is applied to immersed air and provide strongly non-uniform electric field. The efficiency filters mainly depends on the value distribution In this work, two-dimensional computer simulation was constructed study effect different voltages (20, 22, 25, ...

The quality of Al2O3-TiO2 mixed oxides produced in continuous mode by using two original rapid mixers (the impinging jets and the sliding surface mixing device) as precipitation reactors is compared with one obtained by a standard stirred tank. The properties of agglomerate particles strongly depend on the operating conditions and particularly on the type of precipitator used for their production.

The paper is dealing with the presentations of collecting efficiencies of electrostatic precipitators. Whereas the total separation efficiency and effective migration rates respectively bear some problems in interpretation and discussion an observation of the flux of locally precipitated dust should lead to more clarity and an improved insight of precipitation because it is only based on physic...

A sample of airborne dust taken with the standard thermal precipitator consists of two deposits about 1 cm. long and 1 mm. wide obtained from either side of the heated wire (Green and Watson, 1935). These deposits are examined under a microscope and a count is made across each of them to estimate the number of particles collected. The particles commonly have an irregular shape and some consist ...

The waste incineration plants, power generation utility, chemical industry, etc. require the efficient removal of submicrometer particles from raw gases. Wet electrostatic precipitators (WESP) are the most effective control device for fine aerosol from the humid raw gases. They use less energy than mechanical collection devices, have no moving parts to wear, their maintenance costs are lower, p...

Design, fabrication and experiments of a miniature particulate matter (PM) 2.5 sensor based on the surface acoustic wave (SAW) technology were proposed. The sensor contains a virtual impactor (VI) for particle separation, a thermophoretic precipitator (TP) for PM2.5 capture and a SAW sensor chip for PM2.5 mass detection. The separation performance of the VI was evaluated by using the finite ele...

environmental degradation and economic growth are two important proofs in sustainable developmentwhich are followed by steel industry. in this case, energy and environmental damages as sustainabilitypatterns of environment have been investigated in three different dust collectors to select the mostenvironmentally suitable dust collector for electric furnace. in this article, the consumption amo...
