The electric bag composite dust removal equipment fully utilizes the advantages of electrostatic precipitator and bag type dust collector, and effectively makes up for the shortcomings of the two types of dust collectors. The invention has high dust removal efficiency, small equipment resistance and long service life of filter bags. It has low operation and maintenance costs , Small footprint, etc., energy saving and high reliability. It is particularly suitable for the inspection and modification of the electric precipitator of coal-fired boilers, and the dust removal effect is obvious. It has the characteristics of longer service life and more stable operation of the bag, and fully meets the new acceptance standards of environmental protection departments.
Structural composition of electric bag composite dust removal equipment;
1. Fore-stage electric field includes anode and cathode, rapping mechanism, high voltage and low voltage power supply device, etc.
2. The rear bag includes bag cage device, dust cleaning system, poppet valve, pressure difference and temperature detection device, pre-dust coating device, bypass system, and control equipment.
Technical characteristics of electric bag composite dust removal equipment:
1. High dust removal efficiency. The efficiency of the electric bag dust collector is not affected by the specific resistance and particle size of the dust. The emission concentration can be kept below 20 mg / nm3, which is stable for a long time.
2. The low-resistance pre-dusting is reduced, and the dust load of the filter bag is reduced, thereby reducing the resistance increase rate.
3. Due to the small amount of dust collected by the filter bag, the resistance slowly rises, and the dust removal cycle is long, the dust removal cycle of the filter bag can be extended, which can save energy for dust removal and extend the service life of the filter bag.
4. Compared with the traditional bag filter, the electric bag filter's dust removal cycle is 3 to 5 times longer than that of the traditional bag filter, and the compressed air consumption is less than 1/3 of the traditional bag filter. .
5. The coarse particle dust in the smoke and dust that prolongs the service life of the filter bag is collected by the front-stage electric field. After the sedimentation and collection, the remaining fine particle dust slowly enters the bag dust removal area with the flue gas to prevent the coarse particles in the smoke from wearing the filter bag Low running resistance reduces load pressure. For filter bags, a longer cleaning cycle reduces the number of filter bag cleanings. These are all favorable factors to extend the service life of the filter bag. As long as the operation and maintenance are proper, the service life of the electric bag composite dust collector filter bag is several times longer than that of the traditional bag dust collector under the same operating conditions.
6. Low operation and maintenance cost. Compared with the pure bag type dust collector under the same conditions, it has the advantages of high filtering wind speed, low running resistance, and long dust removal period. Therefore, the configuration and air consumption of the luggage system can be greatly reduced, the operating cost can be reduced, and the service life of the luggage can be extended.
Electric bag composite dust removal equipment principle:
In a high-voltage electric field, dust (esp requires inlet humidity less than or equal to 10%) is charged by the ionization of the gas in the previous stage esp. Under the action of the electric field force, it moves to the opposite polarity electrode and is captured As the flue gas is well adjusted (temperature, pressure, humidity and other factors), the early electrostatic precipitator can effectively remove more than 80% of the dust. In addition to the electrostatic precipitator being superior to various dust collectors in terms of running resistance, the technology of the electric bag composite dust collector is complementary . First, the electric bag composite dust removal device is set in front, which can collect a large amount of dust, precipitate the "red star" particles that are not extinguished in the high temperature flue gas, buffer the uniform airflow, connect the bag dust collector in series, and collect a small amount of fine dust afterwards, so that Shut down and discharge. At the same time, when any one of the two dust removal areas is in failure, the other area still maintains a certain dust removal effect and has a strong mutual compensation ability.
It provides a cost-effective solution for the current electrostatic precipitator reconstruction, construction and expansion. In addition, it can also be used for dust removal in building materials, metallurgy and other industries. The new technology of electric bag composite dust removal equipment has great market potential. Due to future emission standards and stricter emission standards, a large number of aging electrostatic precipitators need to be replaced or upgraded. In China, the prospects for the continuous deepening of the research and development of electric bag composite dust removal technology and the continuous improvement of technical level are very broad.
