Dry electrostatic precipitator: this type of precipitator is designed to work above the dew point of the gas stream. Different from wet ESPs, the collecting plates of dry electrostatic precipitators are cleaned by mechanical impulses or vibration. Wet electrostatic precipitator: this type of precipitator is usually applied in saturated gas streams that have 100 percent humidity. It can remove liquid droplets and

The core part of an electrostatic precipitator consists of a row of thin vertical wires (cathode wires) and a stack of large flat vertical metal plates (anode plates). ESP Working Principle The cathode wires are charged with high voltage DC electricity and form a high voltage electric field between the cathode wires and the grounded anode plates

constructed the first large electrostatic precipitator, which was installed at the Riverside Cement Company in Crestmore, California for the recapture of cement kiln dust. This unit remained in service for 54 years. 1.2. Main Characteristics Characteristics Typical Values Operating Voltage, kV 10 to 100

An electrostatic precipitator is a large, industrial emission-control unit. It is designed to trap and remove dust particles from the exhaust gas stream of an industrial process. Precipitators are used in these industries: Power/Electric; Cement; Chemicals; Metals; Paper

We design electrostatic precipitators for use with clinker coolers with or without waste heat recovery in the circuit for a temperature range of 90-400 C. Our deep process knowledge of dust behaviour associated with kilns and raw mills, including how to return dust to the process, has resulted in an effective, highly compact ESP design, which minimises footprint

The scope of works involved upgrading the exhaust gas cleaning process for Lime Kiln 5 by installing a heat exchanger, and converting an electrostatic precipitator into a bag filter. This scope included fabrication, supply, demolition, construction, tie in and commissioning activities and the supply and installation of a 115m exhaust stack was

Jul 18, 2021 A modern electric precipitator from a European manufacturer was commissioned at the process line No. 1 of Topkinskiy Cement (a subsidiary of Sibcem Holding Company). The installation of gas cleaning equipment on the Rotary kiln No. 1, commissioned in 1966, began in 2019. The work was carried out by specialists of a separate subdivision of OOO Sibcemstroy (a subsidiary of AO Holding

Design Of Electrostatic Precipitator for smoke precipitator. Electrostatic precipitation is the most Preferable way to remove solid Particle pollutants (like dust and smoke) or liquid (mist, oil) contained in the gas injected into the environment. This precipitation process is now widely used in apartments, offices and hospitals, as well as workshops, because of its low power consumption and high filtration

Jan 01, 1977 Application of electrostatic precipitator is the most important basic method relating to the emission control in cement industry as well. The most critical dust concerning the separation by electrostatic precipitator in the cement factory is the hot kiln gas dust. At first, corona method of particle charging is discussed

The length of each part of a rotary kiln is designed based on the inner diameter (D) of the kiln shell.. 1) The length of the kiln head overhanging section (l 1): l 1 = (1.2~1.5) D. As the first section of a rotary kiln, l 1 is better not to be designed too long, or the length of the effective parts of the kiln will have to be shortened.. 2) The length of the preheating section (l 2): l 2 = (5

Contemporary dust control techniques in cement industry, electrostatic precipitator - A case study ... design, and system cost analysis. The factory's collected data was the temperature of waste

When there is too much sulfate in the raw meal then part of the kiln gasses are diverted to an Electro static precipitator. The Kiln system sizes are as follows, stages 1-6: Cyclone Diameter/Downpipe Size: 5.4/0.560, 5.4/0.710, 5.7/0.710, 5.7/0.710, 5.7/0.800, 5.7/0.800

Feb 16, 2001 Abstract. Electrostatic precipitators (ESP) are used for gas cleaning in almost every section of cement manufacture. Application of ESP is studied, keeping in view Indian conditions. The characterisation of dust emissions has been done for different units, such as rotary kiln and raw mill, alkali by-pass, clinker cooler, cement and coal mill

The cement dust used in this study was obtained at the raw ma-terial dust precipitator and at the 1st, the 2nd, and the 3rd stage of the clinker dust precipitator in the cement industry.
