Wet electrostatic precipitator (FOG) device overview:
PM2.5 particulate matter is becoming more and more serious, fog and haze day is increasing, coal-fired power plants, iron and steel plants, boilers, waste incineration, building materials and other flue gas emission standards and supervision is more and more strict.
Wet electrostatic precipitator (FOG) for WESP purification device of coal-fired power plants, steel plants, small boilers, waste incineration, flue gas, building materials and other depth, can be very effective treatment of PM2.5 particles (PM0.5, PM10), SO3 acid mist, gypsum rain, ammonia sol, Hg, two dioxin, reduced tail chimney to solve, gypsum rain, white smoke, dust and other standards and ultra clean ultra low emissions.
Wet electrostatic precipitator (FOG) WESP dust collector and conventional dry electrostatic precipitator (ESP) principle is the same, the flue gas environment is different (dry and wet). Direct current high voltage makes the space gas ionization near the cathode line, and the dust particles are charged and moved and deposited on the surface of the dust collecting anode under the action of electric field. The WESP dust is removed by the water film on the surface of the dust collecting anode or by washing.
Wet electrostatic precipitator (FOG) is mainly composed of shell, anode device, cathode device, insulation device, flushing system and high pressure unit.
1, shell: general corrosion resistant material for glass lined steel scales. It is divided into vertical structure and horizontal structure. The shell shape is divided into round and square. According to the actual situation, it can be installed in the upper part of the desulfurization tower, also can be set separately.
2, air intake mode: according to the actual situation may have different settings.
Vertical structure: lower intake, upper air, upper intake, lower vent.
Horizontal structure: flat out into the flat.
3, dust collector anode plate: choose corrosion-resistant materials, all kinds of materials have their respective advantages and disadvantages, according to the composition of the media and temperature and other actual situation selection. Because of the large amount of gas treatment, the anode of the flue gas is plate type and honeycomb type, and the other uses are tubular and honeycomb.
4, discharge cathode: a variety of materials and models can be selected. According to the gas conditions, corrosion-resistant materials are selected, mainly as follows: stainless steel, lead antimony alloy, titanium alloy.
5, insulation device: the main heating methods are electric heating, hot air heating. Prevent the insulating quartz tube from hanging up in the insulation box.
6. Flushing system: intermittent flushing or continuous flushing.
7, in corrosive gas environment operation, shell and internal parts must use anti-corrosion materials manufacturing and anti-corrosion treatment.
Wet electrostatic precipitator (FOG) device features:
1, widely used. Mainly used in power, metallurgy, boiler, chemical industry, waste incineration, building materials and other industries deep purification of wet flue gas, ultra low and ultra clean emissions.
2, simple process: WESP and flue gas desulfurization system integrated design, new and transformation process is simple, compact structure, small footprint. The two transformation can be carried out for a long time without changing the existing desulfurization and dust removal facilities, installed in the desulfurization tower.
3, the amount of flue gas treatment range: thousands to 4 million m3/h (using multiple electric fields or multiple parallel).
4, efficient: PM2.5 particles such as the removal rate of 85 ~ 95%; dust chimney can realize 20mg/Nm3 and export higher 5mg/Nm3 emission standards; SO3 acid mist removal rate of 85 to 99%, greatly reduce the corrosion by flue gas wet stack emission; droplet removal rate of 70 ~ 90%; comprehensive reduction of heavy metals and other pollutants. It can improve the cleanliness of flue gas emission, and solve the problems of gypsum rain and white smoke.
5, other: resistance is small (< 300Pa); operation and maintenance costs are low; service life is more than 30 years.
In view of the coal-fired power plant flue gas dust removal and environmental protection standard of our country increasingly stringent conditions, Xi'an Thermal Power Research Institute in February 2011, independent research and development project of wet electrostatic precipitator (FOG) technology to control the wet flue gas desulfurization tower after carrying droplets and dust, the dust into the atmosphere to achieve discharge standards, PM2.5 is effectively controlled. At present, the technology has carried out demonstration projects in No. 8 unit of Huangtai Power Plant successfully.
Wet electrostatic precipitator (FOG) is the technical principle of
The principle of dry and wet electric dust collector of ESP are the same, conveying DC negative high voltage electric field to the space, the space gas ionization, dust particles and droplets charged under the action of electric field force, moving to the collecting plate (collector), which is collected in the dust collecting pole surface. Dry type electric dust remover by rapping dust shock will be collected ash to ash, and wet electric dust collector is through the collection of the droplets in the flue gas, the dust collecting electrode is formed on the surface of the dust hopper to overflow wash (water bucket).
The difference between wet electrostatic precipitator and dry electrostatic precipitator is the difference of flue gas working fluid, dry flue gas is dry flue gas, the flue gas temperature is higher, and the flue gas basically contains no droplets. The wet ESP is wet saturated flue gas, the flue gas temperature is low, and the flue gas contains a large number of droplets.
Wet electrostatic precipitator is usually installed in wet desulfurization device, after desulfurization, a large number of water droplets are accumulated in saturated flue gas, which is captured by high voltage electric field, which can reduce the probability of gypsum rain formation. At the same time has a good effect on PM2.5, collecting fine particles such as fog, dust emission concentration can reach ≤ 10 mg / m3.
