Comparison of performance of bag filter and electrostatic precipitator


The dust collector is a device for separating dust from the flue gas. It is called a dust collector or a dust collector. At present, electrostatic precipitators and bag dust collectors are the mainstream dust removal equipment in China. So, which one is a bag dust collector or an electrostatic precipitator? Better? The comparison of the performance of the bag filter and electrostatic precipitator is as follows:


Daily business comparison


Bag type dust collector: The entire bag type dust collector operates very stably and has a relatively simple structure. It is equipped with a detection and maintenance platform. Maintenance personnel can observe the air flow and bag usage on the bag type dust collector platform at any time. It is very safe.


Electric precipitator: automatic control is more complicated. High-pressure equipment safety protection is strict. Boiler operation requirements are not high, but equipment management requirements are strict.

Bag type dust collector is also called filter dust collector. It uses fiber woven bags to collect solid particles in flue gas. Its dust removal efficiency is high. Generally it can ensure that the outlet emission concentration is less than 50mg / nm3, and the dust removal effect can be less than 30 mg / nm3 .


At present, the dust removal efficiency of the newly developed bag type dust collector is as high as 99%. Above 99%, it achieves zero smoke and dust emission.

油和观察. Bag Dust Collector: Basically fully automatic control, fewer mechanical parts, and fewer maintenance personnel. It only requires refueling and observation.


Electrostatic precipitator: There are many mechanical transmission parts, many refueling observation parts, high-voltage equipment is inconvenient, there are many maintenance personnel, and the cost is high.

The performance comparison of bag filter and electrostatic precipitator is as follows:


Changes of boiler flue gas


Bag type dust collector: It is related to the filter bag. As long as the filter bag is not damaged, the exhaust gas outlet concentration can be stably discharged. E. Less than 50mg / m3, the ash discharge method can be automatically adjusted according to the system operation.


Electrostatic precipitator: The dust removal efficiency fluctuates greatly. The dust emission concentration fluctuates with the fluctuation of the grid voltage, and the emission is unstable.


Boiler flue gas temperature change


Bag type dust collector: If the temperature of the flue gas is too low, condensation will occur, which may cause the paste bag and the steel structure of the body to corrode. The flue gas temperature is too high, cannot exceed the allowable temperature of the filter material, and it is easy to burn the bag. Therefore, it must be designed next to Smoke system on the road.


Electrostatic precipitator: If the temperature of the flue gas is too low, condensation will also occur, which will not only cause corrosion to the steel structure of the body, but also generate high voltage leakage in the electric field. If the temperature of the flue gas is too high, the plates will be deformed by heat. , The specific resistance of dust will increase and it is not easy to be energized, which will affect the dust removal efficiency. Moreover, the effect is also obvious.


Air leakage from boiler system


Bag type dust collector: For filter bags with poor resistance to oxygen, which affects the service life of the filter bags, such as PPS filter materials, the oxygen content of the flue gas is controlled within 10%, but it does not affect the dust removal efficiency.


Electrostatic precipitator: The increase of air leakage and air volume is equivalent to the increase of the wind speed of the electric field, which affects the dust removal efficiency.


The comparison of the performance of the bag filter and electrostatic precipitator is as follows 5. Comparison of the initial investment of two dust collectors


1. Generally, when the flue gas emission concentration is <200mg / m3, the initial investment in a bag filter is about 10% higher than that of an electrostatic precipitator (four electric fields).

2. The sum of SiO _ 2 and al _ 2o _ 3 in fly ash is greater than 90%, which is not suitable for electrostatic precipitator. When the dust emission concentration is <200mg / m3, initial investment in electrostatic precipitator (large four electric fields) Slightly higher than the cloth dust collector.

3. When the dust emission concentration of the vacuum cleaner meets the environmental protection emission requirement <50mg / m3, the initial investment of the bag filter is about 10% lower than that of the electrostatic precipitator (five electric fields).


The comparison of the performance of the bag filter and electrostatic precipitator is as follows:


Bag type dust collector: The service life of bag type dust collector is generally 3-5 years. Users can replace the bags with electricity and sewage charges saved by efficient dust removal.


Electric precipitator: The main maintenance of the electric precipitator is to replace the cathode plate, anode plate and dust removal vibration system of the electric field. The replacement cycle is relatively long, generally about 5-8 years, but the replacement cost is higher.


The comparison of the performance of bag filter and electrostatic precipitator is as follows


Running power

Bag type dust collector: The main induced draft fan has high power consumption, and the dust cleaning system has low power consumption.

Electrostatic precipitator: The power consumption of the main induced draft fan is low, and the corona power consumption generated by the electric field adsorption of dust is high. The overall calculation shows that the power consumption of the two types of dust collectors is not much different. Generally, the power consumption of the bag type dust collector is lower than Four-field electric dust collector is higher than three-field electric dust collector.

Sewage charges

Bag type dust collector: The flue gas emission can be stabilized within the range of flue gas emission requirements set by the state. It also has the function of assisting the circulating fluidized bed boiler to spray calcium and desulfurize. The desulfurization efficiency is increased by about 15%, and the sewage charge is relatively small.

Electrostatic Precipitator: At present, the best discharge concentration of four-field electrostatic precipitators in China is also above 80 mg / m3, and it is unstable. Each year, hundreds of thousands or even millions of sewage charges must be paid, which is unmatched by bag-type dust collectors. of.


In summary, under the same working conditions, the cost performance of the bag type dust collector is better than that of the electric dust collector.
