For different industries, we need to choose the appropriate dust removal bag according to different working conditions, different industries, and different requirements. Here we talk about the wood machinery industry, where the main purpose of the industry is to filter dust and prevent static electricity. Therefore, we need to focus on these two aspects when making the dust collector bag. In addition to the advantages of high open space, good air permeability, high dust collection efficiency and long service life, the anti-static polyester needle-punched felt cloth bag has the advantages of high open space, good air permeability, and long service life. , In addition to the characteristics of moderate acid and alkali resistance, it also has very good wear resistance. The anti-static polyester needle-punched felt cloth bag is made of polyester fine denier and large chemical fiber filaments to improve the production of polyester (polyester) fiber needle-punched filter felt by the predecessor equipment, which can mix a variety of fibers evenly and quantitatively, and then use multiple mixed open cotton units and The carding unit is conducive to the layering and compounding and gradient transformation of different fibers between the fiber webs. Anti-static polyester needle-punched felt bag is the mainstream of the wood machinery industry. Anti-static wire is introduced into the production process of dust bag manufacturers, which has anti-static properties and is often used for dust purification in chemical plants, or dust purification in flour mills, dust purification in coal powder factories The dust and flue gas generated in the above environment are low in nature, and are easily exploded in case of open fire, sparks, static electricity, etc. In this case, use an anti-static dust removal bag to eliminate the existence of dust and static electricity, and use the entire dust removal process reliably.

The dust filter bag will be damaged due to long-term continuous use, such as failure and other reasons. Therefore, we need to analyze the daily use of the dust cloth bag. The common reasons for the damage of the dust filter bag are mainly reflected in several aspects. For example, we usually remove dust In the case of bag filtration, if the wind speed is too high, the dust removal bag will be damaged; the other is the temperature of the dust removal bag. If the temperature is too high, it may also cause the dust removal bag to burn out; and whether the filter medium of the dust removal bag is not There are various corrosive substances such as acid and alkali, which will directly affect the damage of the dust removal bag. Finally, we need to be able to find a regular dust removal bag manufacturer to produce high-quality dust removal bags, so that we can better Guarantee the quality of our dust collector bag. 1. Dust medium The choice of dust filter bag cloth depends on the dust properties of the dust, and it is necessary to consider whether the dust contains acid, alkali or strong corrosive substances. Select the suitable filter material according to the nature of the dust, so that the filter bag can absorb the dust normally without affecting its service life. 2. Product quality The processing of cloth bags is particularly important. In recent years, some small manufacturers use small sewing machines as processing equipment, and use inferior threads as raw materials for processing, which are fake and real, and the processing level is far behind. So that the filter bag will open lines, cracks, bottoms and other phenomena in a short time of use. Although the size of the cloth bag is slightly smaller, it can also be used, but after absorbing the dust with a larger specific gravity, the bag will drop out after a period of use. 3. Filter wind speed The filter wind speed of the bag filter is too high, which is the main reason for the damage of the dust bag. In recent years, some units have blindly reduced equipment costs and increased profits. When designing a bag filter, the filter wind speed has been increased. In a short period of time, the user has no obvious response, but the service life of the filter bag is shortened. In this way, instead of saving money for customers, it brings a very large economic burden and wastes time. 4. Use temperature The key to the filter bag is to correctly select the dust filter bag suitable for the corresponding dust temperature. If the temperature is too high, the selected dust filter bag will exceed the normal use temperature, the filter bag will shorten the service life in light, and will be burned in a short time in serious cases. Therefore, when selecting the filter bag, the temperature of the dust collector should be measured and calculated, and the corresponding dust filter bag should be selected.

The reasons for the corrosion of dust filter bags are mainly reflected in several aspects. For example, strong oxidants, acid gases, alkaline gases, etc. will cause corrosion. At the same time, if the damage traces from the inside to the outside, the damage is at the contact of the vertical ribs of the dust bag cage, indicating that the vertical rib of the dust bag cage is de-welded or corroded, the dust bag is worn off or the injection pressure is too high, and the injection is too frequent, so that the contact position between the dust collector bag and the dust bag cage is folded and broken, causing damage. 1. Acid gas It mostly occurs in the use of high temperature filter media, mainly sulfide. If the high temperature flue gas contains a lot of acid gas, it is recommended to use a dust filtration bag with better acid resistance. If ordinary dust removal bags are used, the acid-containing flue gas will corrode the fiber structure in the dust removal bags, resulting in a decrease in the strength of the dust removal bags and eventually damage. Damage marks are from outside to inside. Lowering the temperature can reduce the corrosion of the dust bag by the acid gas. Acid gases include sulfur dioxide, sulfur trioxide, hydrogen sulfide, hydrogen chloride, hydrogen fluoride, etc. 2. Alkaline gas It mostly occurs in the working conditions containing ammonia gas, mainly ammonia gas. For damage and acid corrosion, lowering the temperature can reduce the corrosion of the dust bag by the alkaline gas. 3. Strong oxidant If it is not treated for a long time, it is easy to cause the strength of the fiber to decrease, resulting in the damage of the dust bag due to the decrease of strength.

We all know that dust removal bags have their own service life and cycle. If we want to use dust removal bags for a long time, we need to do a few essential aspects: 1. Be sure to buy high-quality dust removal bag products. Of course, different dust removal bag products will be determined according to different working conditions. We must be able to find manufacturers specializing in dust removal bags to make good quality cloth bags, and at the same time meet our working conditions. If necessary, such a filter cloth bag will take a relatively long time. 2. If the dust removal bag is blocked in operation, clean it up in time. Increase the frequency of cleaning the surface of the dust bag, and clean it in time when there is dust accumulation, which can greatly improve the dust removal efficiency of the dust filter bag. 3. The correct installation of dust removal bags can achieve efficient dust removal. The shape, installation method and mechanism of the bag filter bag are also easily damaged, so be careful during installation.

Many friends' factories have dust removal bags for dust removal. After a certain period of use, the effect of the dust removal bags is not ideal. At this time, it is necessary to replace the dust removal bags. When will it be replaced? First of all, after most of the dust removal bags are made, they will have their own service life and service life. When to replace the dust filter bag, it needs to be determined according to the cycle of its use. It depends on how it is used, how long it has been used, and whether it is damaged. The dust bag is often used, and the high-intensity use of the dust collector bag will greatly reduce the life cycle of the dust bag. Another aspect is the material of the dust removal bag itself, and whether it is produced by a professional dust removal bag manufacturer, that is, whether the product quality of the bag is excellent. Therefore, we comprehensively consider that the replacement of dust removal bags is affected by the following factors. 1. Look at the frequency of use of the dust filter bag, how many hours it has worked, whether it is close to the production life of the dust filter bag, and if it is closer, it needs to be replaced. The longer the running time, the shorter the cycle of the dust collector bag. 2. Find out how the dust concentration is in the working conditions of the factory. If the concentration is dense and the dust removal workload is huge, the service life of the dust removal bag will be accelerated. 3. If you work at high intensity every day, it will lead to a short service life of the dust bag, which is about 1-2 years. A good quality dust bag is about 2-3 years old.

The application range of glass fiber dust removal bags needs to be selected according to the characteristics and characteristics of their own dust removal bags, and then combined with the working conditions of different industries. First of all, the material of each type of dust filter bag is different, and the characteristics are also different. Each type of filter material has its own advantages and disadvantages. Let's analyze the characteristics of glass fiber material. The advantages are mainly good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but there are also disadvantages: brittleness and poor wear resistance. Therefore, we will also match other filter materials for combined production according to the weakness of our own glass fiber. According to the analysis of the characteristics of the glass fiber dust bag, the current glass fiber bag is mainly used in the flue gas industry, non-ferrous metal, dust industry, chemical industry, steel, incineration and carbon black industry. Of course, in order to have more extensive and perfect the weakness of our own glass fiber, we will add some materials, such as glass fiber long glass fiber or short glass fiber reinforced products, such as glass fiber reinforced nylon, glass fiber reinforced pp, glass fiber reinforced PBT, etc.; In the actual purchase process, we still have to choose according to the working conditions of the factory, especially the size of the cloth bag, the installation of the cloth filter bag, and what kind of filter cloth bag is suitable for.
