LONGKING HZdsp-33f-s HZ-WESP wet electrostatic precipitator

The wet electrostatic precipitator is mainly installed in wet saturated flue gas as the final precision treatment environmental protection equipment. Its dust removal performance is independent of the characteristics of fuel dust, and it can effectively capture fine particles. The outlet dust concentration can reach below 10mg/m3. It has the advantages of no secondary dust, high dust removal efficiency, low pressure loss, no moving parts, basically maintenance free, compact structure and small footprint. In recent years, the effectiveness of wet electrostatic precipitators in meeting ultra-low emissions and controlling PM2.5 has been unanimously recognized by industry experts, and their application fields are extending from the power industry to other non power industries.

Wet electrostatic precipitators are used in biomass boilers as ultra clean emission devices, and a spray washing tower must be added in front of them. This is similar to the multi tube cyclone dust removal required for bag dust removal. On the one hand, wet saturated flue gas is formed by humidifying and cooling the flue gas, ensuring the condensation and capture of fine particles such as PM2.5. On the other hand, because the spray circulating water is alkaline water quality of plant ash, it can further remove acidic pollutants such as SO2 and HCI in the exhaust gas. The system process is as follows:


The wet electrostatic precipitator applied to the treatment of biomass boiler exhaust gas can all use stainless steel devices without further anti-corrosion treatment. Even in the event of a short-term spray water pump failure or high-temperature open flame operation of the boiler, the wet electrostatic precipitator can operate normally, greatly reducing the requirements for boiler operators. It is very suitable for the dust removal and efficiency improvement of biomass boilers that cannot use bag dust removal, such as wood chips, bamboo chips, sugarcane bagasse, etc.

Practice has proven that the operating conditions and fuel characteristics of different biomass boilers vary greatly, and simply using bag filters cannot meet the increasingly strict environmental emission requirements of the country. Especially due to unsuitable working conditions, many biomass small boilers in the furniture industry frequently experience bag burning and breakage, causing unbearable maintenance costs for users. As an advanced flue gas treatment technology, wet electrostatic precipitator has a simple structure, basic maintenance free, low operating cost, strong ability to remove fine smoke and dust, and can also achieve the removal of multiple pollutants. Especially suitable for smoke and dust control of special biomass boilers such as wood chips, bamboo chips, sugarcane bagasse, etc., it has incomparable advantages in reliability and dust removal efficiency,
