Comparison of filter filter collector and bag filter

The filter cartridge dust collector is also commonly known as the filter cartridge dust collector.

Cartridge dust collector is a kind of pulse filter cartridge dust removal equipment, also called filter element dust collector, filter cartridge dust collector has the characteristics of small size, large filtration area, good filtration effect, small pressure loss, long service life of filter cartridge, fast and convenient installation and maintenance, and continuous use.

Pulse cartridge dust collectors are commonly used for:

1. Cement plant: dust removal of crusher, grinder, coal mill, conveyor, warehouse roof, raw meal mill, cement mill, packaging and other links;

2. Metallurgical plant: dust removal of electric furnace, blast furnace, desulfurization furnace, induction furnace, casting, sandblasting, cylinder furnace and other equipment;

3. Chemical plant: dust removal of plastic fibers, resins, tires, rubber, coking, bleaching powder and packaging;

4. Food and medicine: additives, drying processes, flour and grain processing, sugar-coated tablets and dust removal in packaging links;

5. Aluminum plant: dust removal of fluidized bed dry cleaning tower, venturi jet dry cleaning tower, self-baking dry cleaning tower, carbon dust, anodic crushing, electrolytic aluminum and other links;

6. Dust purification and materials in power plants, cigarette factories, wood factories and other related workshops.

The bag filter is composed of an inlet of dusty gas to an outlet of purified flue gas, and the body structure is composed of an air inlet pipeline, an air inlet chamber, a bag room, an ash hopper, an ash discharge valve, an outlet pipeline, a reverse blowing system and an ash cleaning control system.

The body of the bag filter is an all-steel structure, and is designed by an anti-thermal expansion mechanism, the shell is made of lightweight rock wool board double-layer insulation, the appearance is protected by galvanized sheet, and the new process of pulling rivets is used, and the flower plate is used with cold stamping and rolling forming process, which not only increases the strength but also ensures the quality of the equipment.

The bag filter uses a specially treated high-temperature resistant glass fiber bag, which has good bending resistance, wear resistance, strength and thermal shock performance, and can be treated accordingly according to different flue gas characteristics to meet the requirements and emission standards of the demander.

Comparison of the performance of filter filters and traditional baghouses.

1. The effective filtration area has been doubled.

2. The differential pressure is reduced and the air volume is improved.

3. The air-to-cloth ratio is reduced, which effectively improves the filtration efficiency.

4. The working efficiency of the pulse backflushing system is improved and energy consumption is saved.

5. Venturi tube and skeleton are exempted, and the structure is simple.

6. The filter cartridge elements become shorter and fewer, which is conducive to installation.

7. Greatly improve the service life of dust removal spare parts and reduce the number of shutdowns of equipment.

8. The structure is compact, which greatly reduces the volume of the equipment and saves the floor space.

Generally, the wind speed of the bag filter can be reached, below the glass fiber lamination, below the thermal power plant, the good is left and right, biomass power generation, the wind speed may be better than the following, and the wind speed of the bag filter at room temperature is controlled; It is advisable to control the air speed of high-temperature bag filtration.

The size of the filter wind speed of the bag filter is related to many aspects, mainly depends on the dust characteristics and concentration, gas characteristics, filter material varieties and ash cleaning type. For the filtration of fine particles, large concentration, large viscosity, strong abrasive pecking and high temperature and high humidity gases, the filter wind speed of the bag filter should be a small value, and a large value should be taken otherwise. For the filter material, the resistance of the woven fabric is large, the filtration wind speed is small, and the porosity of the needle felt is large.

Bag filter.

Bag filter is an efficient dust removal equipment, which is mainly used in dust control in industrial production. It consists of one or more bags, which are usually made of special materials that effectively capture fine dust particles.

First, the working principle of the bag filter.

Baghouses are filters that capture dust particles in the air and separate them from the airstream. Filters consist of one or more layers of fabric or nonwovens, which are typically made of polyester, polypropylene, polyurethane, or other materials.

The surface of these fabrics or nonwovens has a special fiber structure that effectively traps dust particles in the air.

Second, the advantages of the bag filter.

High efficiency: The filter of the baghouse can effectively capture the fine dust particles and make them meet the safe emission standards.

Reliability: The filter bags of the baghouse can be used for a long time, so their maintenance costs are low.

Ease of Maintenance: The baghouse's filter bags are easy to replace, making maintenance much easier.

Strong adaptability: The bag filter is suitable for various industrial production environments, including chemical, electric power, metallurgy, building materials and other industries.

Third, the shortcomings of the bag filter.

Short bag life: Bag filters have a relatively short bag life and need to be replaced regularly, so their operating costs are high.

High requirements for the size of dust particles: The diameter of the dust particles that need to be captured by the baghouse is relatively small, so its application range is relatively narrow.

Overall, the bag filter is an efficient, reliable, and easy-to-maintain dust collection equipment that is suitable for dust control in various industrial production environments. Its advantages include high efficiency, reliability, and ease of maintenance, while disadvantages include higher costs and higher requirements for dust particle size.

Features of the bag filter include:

Efficient dust removal: The bag filter can effectively filter out fine particles and has a high dust removal efficiency.

Wide range of application: It can be applied to a variety of industrial fields and occasions, such as pharmaceutical, cement, metallurgy and other industries.

Low operating cost: Compared with other dust removal equipment, the operating cost of the bag filter is lower and the maintenance is relatively simple.

Compact structure: The bag filter is small in size, compact in structure, small in footprint, and easy to install.

Convenient operation: The operation is simple and can realize the fully automatic operation with a high degree of automation.

Environmental protection and energy saving: Bag filter is an environmentally friendly and energy-saving equipment, which is in line with the development trend of modern industry.

Filter media is used to make bags or cylindrical filter bags to capture dust in the flue gas.

It is characterized by the fact that it can filter 99% of dust.

The dust removal and filtration of the vacuum truck have their own advantages and disadvantages, and the specific choice of which filtration method is better depends on the actual needs and scenarios of users.

The advantage of bag filtration is that the filtration effect is good, because the surface of the bag is smooth, it can effectively filter out fine dust and particles, and the filtration area is large, which can meet the requirements of large-flow dust removal. However, the disadvantage of bag filtration is that the filtration area is relatively small, the bag needs to be replaced and cleaned frequently, and the maintenance cost is high.

The advantages of cartridge filtration are that the filtration area is large, which can meet the requirements of high-flow dust removal, and the filter element has a long life and low maintenance cost. However, the disadvantage of cartridge filtration is that the filtration effect is relatively poor, because there are wrinkles on the surface of the filter element, and fine dust and particles are easy to remain in the filter element and are difficult to remove.

Therefore, for scenarios that require high filtration effect, such as indoor cleaning, hospital operating rooms, etc., bag filtering may be more resistant to coarse lesions. For scenarios that require a large filtration area and low maintenance costs, such as factories, warehouses, etc., cartridge filtration may be more suitable.

Most of the dust removal filters on the market are still filter elements, and I have never seen a cloth bag.

1. The hard filter material of the filter cartridge or filter bag is folded and arranged to form a cylinder, without skeleton, short, with a large spacing between the cylinders, thorough ash cleaning, and no secondary pollution.

2. The cloth bag is sewn into a filter bag with soft filter material, which is inserted into the skeleton welded by steel bars (commonly known as the keel frame), the filter bag is densely distributed, and the filter material is long polyester fiber and its post-treatment material is mostly a single-layer ordinary industrial polyester cloth.

3. Filtration principle: surface filtration principle: the dust of the filter cartridge dust collector does not penetrate deep into the filter material, and the principle of depth filtration. The dust of the bag filter penetrates deep into the filter material, and the dust layer is established on the outer surface of the filter material to maintain the dust removal efficiency.

The difference between a bag filter and a cartridge dust collector:

1.The principle of filtration is different.

The dust of the bag filter penetrates deep into the filter media, some dust is trapped on the outside of the dust removal bag, and the purified air is discharged through the fan inside the filter media.

The dust of the filter cartridge dust collector does not penetrate deep into the filter material, and it is deeply filtered.

2.The filter material is different.

The inside of the bag filter filter is used, and the filter material is mostly a single-layer ordinary industrial polyester cloth, which is supported by a dust bag cage.

The filter cartridge dust collector is a filter cartridge, which does not need to be supported by a skeleton, is short, has a large spacing between the cartridges, cleans the ash thoroughly, and has no secondary pollution.

Cartridge dust collector and bag filter are two types of equipment that are widely used in the field of industrial dust collection. They have different structures and properties and are suitable for different types of dust handling.

The structure and filtration principle of the cartridge dust collector and the bag filter are different. The characteristics of the filter cartridge and the cloth bag are also very different.

The filter cartridge has good air permeability and is not easy to be contaminated with dust, while the cloth bag has poor performance and poor air permeability and is easy to be contaminated with dust. Therefore, when dealing with dirty air with high humidity, it should be treated to prevent condensation from causing "sticky bags". Baghouses are suitable for the handling of dry dust, which requires the humidity of the purified air.

The cartridge or bag is folded into a cartridge with the rigid media. The ash is cleaned carefully, and there is no secondary pollution.

The cloth bag is sewn into a filter bag with soft filter material and put on the skeleton of steel welding. Filter bags are densely distributed vertically. The filter material is polyester fiber, and the post-treatment material is mostly single-layer ordinary industrial polyester fabric.

In terms of the difference in filtration principle, the cartridge dust collector dust does not penetrate deep into the filter material. Baghouse dust penetrates into the filter material, and a dust layer is established on the outer surface of the filter material to maintain dust removal efficiency.

In terms of shape and volume, the filter cartridge is smaller in size, lighter in weight, more flexible in assembly, and takes up less space. However, the baghouse is huge in appearance, heavy in volume and large in installation space. Another advantage of the cartridge is that the cartridge is less worn and does not need to be replaced as often.

When the filter cartridge dust collector is working, the back and forth friction seriously damages the filter bag and needs to be replaced frequently.

When used, the dust removal efficiency of the filter cartridge dust collector is higher than that of the bag filter, and the cost and maintenance cost are lower than that of the bag dust collector, which is very suitable for purifying the smoke and dust generated in the process of welding and grinding, which is the main development direction of the industrial dust collector at present. However, baghouses also have their advantages. It is suitable for the purification of fine dry fumes, and is more reliable when dealing with fumes and dusts that are in danger of bursting and sparks.

Aonasen Environmental Protection is a domestic company that makes bag filters. Committed to passing the environmental impact assessment of enterprises.

Bag filter.

The dust removal efficiency is high, generally more than 99%, and the dust concentration of the outlet gas of the dust collector is within tens of mg m3, which has a high classification efficiency for fine dust with sub-micron particle size.

The range of air volume is wide, the small one is only 1 min m3, and the large one can reach 1 min tens of thousands of m3, which can be used for flue gas dust removal in industrial furnaces and kilns to reduce the emission of air pollutants.

The structure is simple, and the maintenance and operation are convenient.

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.

Personal suggestion: In this regard, I suggest you look for manufacturers in the Kunshan area, Aunason Environmental Protection Company focuses on waste gas treatment and provides one-stop solutions, you can consider it.
