Free design solution provided for electric bag composite dust collector in thermal power plant
Electric bag composite dust collector is a dust removal equipment developed in recent years. Especially suitable for dust removal of high ash concentration flue gas in thermal power plants and meeting the requirements of current national emission standards.The electric bag composite dust collector is an efficient and energy-saving flue gas purification equipment, which has the advantages of high dust collection efficiency, large flue gas processing capacity, long service life, and low maintenance costs,The electric bag composite dust collector designed and produced by Shiheng Environmental Protection Company is a new energy-saving and efficient dust collector with a two-stage dust removal mechanism of electrostatic dust removal and filter bag filtration dust removal. It has the characteristics of long cleaning cycle, long service life, and low operating resistance. The dust removal power has high efficiency and stability, and can effectively achieve the intention of efficient dust removal.
The system structure of the electric bag composite dust collector in a thermal power plant is divided into two stages. The front stage is the electric dust removal zone, and the rear stage is the bag dust removal zone. The two stages are organically combined in a series structure. A special diversion and drainage device is used between the two-stage dust removal methods to clearly separate the two areas. The electrostatic precipitator is set at the front, which can not capture a large amount of dust, settle the unextinguished particles in the high-temperature flue gas, and buffer the uniform airflow; Connect the filter cartridges in series to collect a small amount of fine dust and strictly control the emissions. At the same time, when either of the two dust removal areas malfunctions, the other area maintains a certain level of dust removal effect and has strong mutual compensation.
Performance characteristics of electric bag composite dust collector in thermal power plant:
The front stage electrostatic precipitator and the rear stage bag filter are arranged in series, sharing the same shell, and a special drainage device is used between the two dust removal methods. It has the following advantages:
1. Widely applicable, with high efficiency and stability in dust removal efficiency. The dust removal efficiency of this equipment is not affected by high specific resistance fine dust, coal type, or ash characteristics. The emission concentration is easily achievable below 20mg/m3 and remains stable for a long time.
2. Save operating costs. The operating resistance is 500Pa lower than that of a pure bag filter, and the power of the induced draft fan can be reduced by 1.74KW per 10000m3/h.
3. Long cleaning cycle, low energy consumption of gas source, and long service life of filter bag. Compared with pure bag filters, the dust collected by the dust filter bag is only 1/4 of its inlet, the cleaning cycle is more than twice as long, the compressed air consumption is less than 1/3, and the service life of the filter bag can be extended by 2-3 years.
4. Compact structure, small footprint, especially suitable for the efficiency improvement of old electrostatic precipitators.The advantages of electric bag composite dust collectors are significant, as they can utilize the original shell of the electrostatic precipitator without increasing land occupation or requiring high maintenance costs like bag filters.
