What are the advantages and disadvantages of electrostatic precipitator? as follows: The electrostatic precipitator is a plate type horizontal single-chamber dual electric field electrostatic precipitator, which is mainly used in metallurgy, building materials, power and other departments. Compared with the vertical electrostatic precipitator, it has the following advantages. The horizontal electrostatic dedusting equipment along the airflow direction can design multiple electric fields, and each electric field can apply different voltages according to the different requirements of the dedusting, thereby improving the overall efficiency of the dedusting equipment. When it is necessary to increase the dust collection area to improve the dust removal efficiency, it is easier to extend the length of the electric field, and the vertical electric dust removal equipment should not be too high. The horizontal electrostatic precipitator can easily ensure that the airflow is evenly distributed along the cross section of the electric field when handling a large amount of smoke.
The horizontal electrostatic precipitator of the hook is lower than the vertical height, which is convenient for maintenance.
静电除尘设备在使用时有以下要求。 What are the requirements for using electrostatic precipitator? The electrostatic precipitator has the following requirements when using it. This series of products are plate-shaped, figure-shaped, and the corona is a pole-frame star wire. Simple structure, low air velocity, low pressure loss, wide flue gas particle size after treatment, large volume of purified gas, low energy consumption, and capable of purifying dusty flue gas with high temperature
Not suitable for handling high concentrations of dusty gases. Generally, a certain dusty concentration is required
What is a wet electrostatic precipitator? What industries are they currently used for? What are the advantages and disadvantages of electrostatic precipitator? Electric dust removal equipment using wet dust removal is called wet dust removal equipment. It uses overflow or uniform spraying to keep a layer of water film on the surface of the dust collecting rod. When the dust reaches the water film, it flows along the water stream to achieve the purpose of dust removal. Wet dust removal completely avoids secondary dust, and the dust removal efficiency is high. Because the surface of the electrode plate has a thin water film, no back corona is generated, and it is not limited by the dust ratio. In addition, the wet electrostatic precipitator can also purify harmful gases such as 302 and ii. wait. Its disadvantages are the problems of mud and wastewater treatment and the corrosion protection of the material structure. What is dry and wet mixed electrostatic precipitator? What are its advantages? The electrostatic precipitator combined with wet and dry method is called dry and wet mixed electrostatic precipitator. In order to make full use of the respective characteristics of the wet and dry type. Of course, the two are arranged in series in the casing. The dust in the gas is first removed from the dry electrostatic precipitator before 80 ° C,? 90 |. The rest was removed from the wet electrostatic precipitator. In this way, the overall efficiency of the dust removal equipment can reach a very high level, the dust concentration at the gas outlet can be lower than the dust removal equipment, and the volume and cost of the dust removal equipment can be reduced. Most of the recovered dust is dry ash, sludge and sewage are very less..
If the dust removal equipment is used to purify the high-temperature flue gas, the sludge can also be sent to a drying tower for drying, so that all the recovered dust is dry ash. In addition, due to the use of primary wet dust removal, harmful gases such as 302 can also be removed from the flue gas. If you add 30 乇, 0 乇 and 0 003 乇, the effect will be better, but pay attention to the problem of corrosion prevention.
What is wet dust removal equipment? What are the advantages and disadvantages of electrostatic precipitator? Wet dust removal equipment is a device that removes dust using the action of water or other liquids and dust-containing gases. When dust particles meet sprayed water droplets, water films, or wet walls and devices, wetting, condensation, diffusion, and sedimentation occur And other processes to separate them from the gas and achieve the purpose of purifying the gas. Compared with other dust removal equipment, wet dust removal equipment has the following characteristics. Under the same energy consumption conditions, the dust removal efficiency of wet dust removal equipment is higher than that of dry dust removal equipment. The efficiency of wet dust removal equipment (Venturi dust removal equipment) is as low as 0.1 1! Its dust removal efficiency is still very high ... Wet dust removal equipment can simultaneously purify harmful gases and is suitable for processing high temperature and high humidity smoke and viscous dust. In this case, the use of dry dust collectors is often limited by various conditions. Wet dust removal equipment has a simple structure, low investment at one time, small size, and low investment. It is suitable for dust removal projects in mining, metallurgy, machinery, light industry, building materials and other industries. Wet dust removal equipment can purify the gas while removing the dust. When the flammable gas contains flammable components, the equipment can be prevented from exploding. Secondary pollution. However, the wet dust removal equipment has the following main disadvantages.
Secondary pollution, so it has not been widely used in dry dust removal equipment.
