What are the advantages and disadvantages of bag filters, who knows?

The advantages and disadvantages of baghouses are as follows:

Advantages: The processing efficiency of granular materials is high, and the dust removal effect can reach more than 99%.

It is suitable for the treatment of high temperature, high humidity and corrosive gases, and can work normally in harsh industrial environments.

The operation and maintenance are relatively simple, and the cloth bag is easy to replace.

The cloth bag has a certain elasticity and flexibility, which can effectively prevent damage to equipment, crushing and other problems.

Disadvantages: The initial investment cost of the dust collector is high.

The cloth bag is easy to clog during use, needs to be cleaned, and the cycle is short.

After a long period of operation, the bag is easy to age, deform and wear, resulting in a decrease in dust removal efficiency.

For some special particulate materials (such as fibers, droplets, etc.), it cannot be effectively filtered.

The equipment occupies a large area.

In a word, the bag filter is a relatively common dust removal equipment, which has efficient and stable dust removal performance, but there are also some shortcomings, which need to be selected according to the specific situation.

Bag filters are the most widely used in many industrial sectors such as steel, non-ferrous metallurgy, chemical industry, machinery, building materials, electric power, light industry, textile, food, and transportation.

Baghouses have the following advantages:

1) The dust removal efficiency is very high, generally it can reach 99%, and it can capture fine dust particles with a particle size greater than microns, which can meet strict environmental protection requirements.

2) Stable performance. Changes in working conditions such as air volume, gas dust content, and temperature have little impact on the dust removal effect of the bag filter.

3) Easy dust disposal. The bag filter is a dry purification equipment that does not require water, so there is no sewage treatment or mud treatment problem, and the collected dust is easy to use.

4) Flexible use. The air volume can be from hundreds of cubic meters per hour to hundreds of thousands of cubic meters per hour, and can be used as a small unit directly located indoors and nearby, or it can be made into a large dust removal room.

5) The structure is relatively simple, the operation is relatively stable, the initial investment is less, and the maintenance is convenient.

But there are also some drawbacks to baghouses.

1) There is a limit to the ability to withstand temperature. Cotton and wool filter media can withstand temperatures of 80-95 degrees, synthetic fiber filter media can withstand temperatures of 200-260 degrees, and glass fiber filter media can withstand temperatures of 280 degrees. When purifying flue gases with higher temperatures, measures must be taken to reduce the temperature of the flue gases.

2) Some flue gas contains more moisture, or the dust carried has strong hygroscopicity, which often leads to the adhesion of the filter bag and the blockage of the filter material. In order to ensure the normal operation of the baghouse, necessary insulation measures must be taken to ensure that the moisture in the gas does not condense.

3) Some types of baghouse dust collectors have poor working conditions, and when inspecting and replacing the filter bags, they need to enter the box.

The advantage of baghouses is that they meet the particulate emission standards and can meet the stringent emission requirements. And the operation is relatively stable. His disadvantage is also obvious: we need to change the dust bag regularly, which is time-consuming and labor-intensive.

Baghouse is a common gas purification device, which uses a fiber bag filter to filter the exhaust gas, and traps the dust and particles in it on the surface of the bag, so as to achieve the purpose of purification. Its advantages and disadvantages are as follows:

Advantages: High dust removal efficiency: The dust removal efficiency of the bag filter can reach more than 99%, which can effectively filter out the fine particles and dust in the exhaust gas, and the purification effect is good.

Large flow rate of treated gas: The bag filter has a simple structure and a large flow rate of treated gas, which is suitable for large-scale industrial production sites.

Ease of operation and maintenance: Baghouses are chemical-free, relatively simple to operate and maintain, and easy to change and clean bags.

Disadvantages: Higher cost: Compared with other dust removal equipment, the cost of bag filter is higher and requires higher investment cost.

Large footprint: Because the bag filter requires more filter bags, it occupies a large area and needs to occupy a certain amount of space.

Easy to be blocked: If the treated exhaust gas contains more moisture, oil and other substances, it is easy to cause the filter bag to be blocked, which needs to be cleaned and replaced, which increases the maintenance cost.

Not suitable for high temperature and corrosive gases: The filter bags of bag filters are generally made of polyester, glass fiber and other materials, and are not suitable for the treatment of high temperature and corrosive gases.

However, the advantages of the dust collector are high filtration accuracy, particulate matter emission standards, and stable operation. His shortcomings are: Decide to replace the filtered dust bag. The cost varies depending on the working conditions.

**Also different.

The advantage of the baghouse is the high filtration accuracy and accuracy. Particulate matter emissions meet the standard. The line is relatively stable. It is widely used. The downside is that the filter bags need to be replaced regularly.

The bag filter has a good cleaning effect, and its heat resistance can reach a continuous temperature of 190 and an instantaneous temperature of 200. It is currently the most widely used modal dust removal device in the world. Let's take a look at the advantages and disadvantages of bag filters!

Bag type dust collector.

1. Advantages of bag type dust collector.

1. The dust removal efficiency is high, and it can reach above.

2. There are few ancillary equipment, and the technical requirements are not as high as those of electrostatic precipitators.

3. The celery section can capture dust with high specific resistance and difficult to remove electrostatic precipitators.

4. The performance of the bag filter is stable and reliable, the adaptability to load changes is good, the operation and management are simple, and it is especially suitable for capturing fine and dry dust, and the collected dry dust is easy to handle and utilize.

5. The main function of the dust collector is dust removal, so there is a pre-dust collection mechanism in terms of functional design, which can overcome the shortcomings of the dust directly washing the Rongdan first source easy to wear filter cartridge, and can greatly improve the dust concentration at the entrance of the dust collector.

Advantages of bag type dust collector.

6. The service life is not too short, generally speaking, it can be used for up to 2 to 3 years, if it is properly maintained, and the filter element is replaced regularly, it will be more useful.

Second, the shortcomings of the bag filter.

1. When it is used to deal with dusty gases with high relative humidity, thermal insulation measures should be taken, especially in winter, so as not to cause "paste bags" due to condensation.

2. When used to purify corrosive gases, appropriate corrosion-resistant filter materials should be selected, and cooling measures should be taken for the treatment of high-temperature flue gases. The flue gas temperature is lowered below the temperature that the filter bag can withstand for long-term operation, and the filter material with high temperature resistance is used as much as possible.

3. The resistance is large, and the general pressure loss is 1000 1500pa.

Disadvantages of bag filter.

1. The dust removal efficiency of the bag filter is very high, and the bag dust collector can capture fine dust with a particle size greater than microns, and the dust removal efficiency can reach more than 99%.

2. The bag filter is very flexible to use, can be placed directly indoors, and the air volume can be increased from 100 cubic meters per hour to hundreds of thousands of cubic meters per hour.

3. The structure of the bag filter is relatively simple, the operation is relatively stable, the initial investment is small, and the maintenance is also very convenient. Therefore, the bag filter is widely used, which can be used to eliminate dust pollution and improve the environment.

4. The dust is very easy to deal with, the bag filter is a dry purification equipment, and the bag filter does not need water, so there is no sewage treatment problem and mud treatment problem.

The dust removal efficiency of the bag filter is very high, generally above 99, and it has a high classification efficiency for fine dust with sub-micron particle size.

The bag filter has a wide range of air volume, which can be used for flue gas dust in industrial furnaces and kilns, and can also reduce the emission of air pollutants.

The structure of the bag filter is very simple, and it is also very convenient for maintenance operations.

On the premise of ensuring the same high dust removal efficiency, the cost is lower than that of electrostatic precipitators.

When using high-temperature resistant filter materials such as glass fiber, PTFE, P84, etc., it can operate under the condition of more than 200 high temperatures.

It is not sensitive to the characteristics of dust, and is not affected by dust and resistance.

1.The dust removal efficiency is very high, and the bag dust removal relies on the filter bag made of fiber filter material, and the most important thing is to purify the gas through the dust layer on the surface of the filter bag. Therefore, the gas efficiency of bag dust removal for purified dust particles is high, generally reaching 99%.

If the filter material used has good performance, its dust removal efficiency can even be achieved, and the performance is stable.

2.The operating system is relatively simple, easy to run, easy to maintain, easy to handle dust, and flexible to use. It can be used on any occasion.

3.Environmentally friendly, the baghouse is a dry purification equipment that does not produce sewage and sludge because it does not require the use of water. And the collected dust is easy to use.

4.Small, the bag filter can also be made into a small one for convenience, and it can be installed on or near the dust collection equipment. The compact baghouse is particularly suitable for dust collection that disperses dust sources.

5.The efficiency is good, and the dust-containing gas has little impact on the dust removal efficiency and resistance of the bag filter in a considerable range.
