Structural Design and Features of Dust Collecting Bag of Botou Junzheng Company
The dust bag is the heart of the bag dust collector, and is generally called the filter bag, dust bag, dust bag, dust bag, dust bag, dust bag, etc. The dust bag is the key part of the operation of the bag type dust collector. Generally, the cylindrical bag is suspended vertically in the dust collector.
Dust removal bag structure design:
Dust removal bag is generally divided into pulse type dust removal bag, vibration type dust removal bag, and reverse blow dust removal bag according to different dust removal methods.
Depending on the shape of the dust bag, there are round bag type, flat bag type and envelope type.
Dust removal bag Dust removal bag also has different bag mouth and bag bottom planning methods to choose from.
Dust removal bag features:
The fabric and plan of the dust removal bag should strive for filtering, easy dust peeling and durability.
1. The capillary fiber oil-absorbing dust-removing cloth bag is composed of a pre-filter layer, a main filter layer and a wire mesh cover. It is designed to effectively absorb grease from liquids. The open space rate in the filtered data is as high as 80%, which greatly improves the service life of the product. Oil absorption up to 12-20 times the weight of the dust bag (depending on fluid and grease characteristics and flow rate)
Second, the seamless seamless dust bag is made of pure polypropylene capillary fiber by hot-melt blow molding. The outer layer is thicker and deeper filtering materials to provide layered filtering; the inner-diameter large-diameter filter element is used to further enhance the overall deep filtering effect and improve the ability to contain impurities. The average service life is more than five times the average polypropylene dust bag. The filtering accuracy is 3um. The collar is a plastic ring.
Third, the silk screen dust bag can choose materials include nylon single wire mesh, polyester single wire mesh, and polypropylene multi-strand wire mesh. Filtering accuracy is 20um.
The main materials of dust-removing bag are: polyester needle-punched felt dust-removing bag, water-repellent and oil-repellent needle-punched felt dust-removing bag, anti-static dust-removing bag, three-proof dust-removing bag, acrylic dust-removing bag, flumes dust-removing bag, metas dust-removing bag, PPS dust-removing Cloth bags, P84 dust bag, 208 dust bag, etc. And the thickness of various raw materials for dust-removing cloth bags is different. Among them, the general-purpose boiler PPS high-temperature dust-collecting cloth bag for boilers for flue gas desulfurization and dust-removing is a kind of raw material of the bag. It has high air permeability, unique air-to-ground air-height, high Collecting power and other strengths has won widespread attention in shopping malls, and the amount of use accounts for most of the entire dust bag.
The degree of surface lubrication of the dust filter bag filter material has a great influence on the dynamic running resistance of the filter material. The initial resistance of the dust filter bag filter depends on the air permeability of the filter itself, and the resistance during operation is many times larger than the initial resistance. The running resistance depends on the degree of lubrication on the surface of the filter bag and the dust removal effect. The choice of cloth for the dust removal bag depends on the dust properties of the dust, and whether the dust contains acids, alkalis or strong corrosive substances must be considered. According to the nature of the dust, a suitable filter material is selected, so that the bag can normally absorb the dust without affecting its service life. The correct selection of the dust bag with the appropriate dust temperature is the key to the bag. If the temperature is too high, the dust bag used will exceed the normal use temperature. The light bag will shorten the service life, and it will be burned in a short time. Therefore, when selecting the bag, the inlet temperature of the dust collector must be calculated. Choose the appropriate dust bag.
Summary: Dust removal bag produced by Junzheng Company features: filtration accuracy, high toughness, damage resistance, no fiber free, and can be used repeatedly.
The principle and definition of the dust bag is a high-efficiency dust filter, which has good ventilation performance, high power of the dust bag, and has certain acid resistance, alkali resistance and heat resistance. Multilateral brushing is used in the weaving process. The thickness of the fabric is improved, and the elasticity is provided. The dust removal accessories have a very good effect, and the dust removal rate can reach 99.99%. The dust removal bag is made of polyester staple fiber or long fiber. The service life is generally 4-6 times that of glass fiber fabric. It has good air permeability, high dust collection rate, dust removal capacity, and dust removal power can reach 98.99%. The dust-removing cloth bag is dirty during the operation of the bag-type dust collector. Generally, a cylindrical pulse-type cloth bag is suspended vertically in the dust collector. The dust-containing gas enters the dust collector from the air inlet and passes through the deflector of the ash bucket to make the Part of the large particle dust was separated by the effect of inertia and fell directly into the ash hopper. Dust-containing gas enters the bag filter area of the box, and most of the dust is captured on the outside of the bag. The clean gas enters the inside of the bag through the filter material, and the purified gas enters the upper case through the mouth of the bag, and then is discharged through the air outlet. The cage inside the bag is used to support the bag and prevent the bag from falling. At the same time, it helps to remove and redistribute the dust cake.
Dust removal cloth bags require many processes from raw materials to products, and each process requires strict control. If the filter bag presents quality problems, it will mostly appear in filter bag raw materials, bag mouth diameter, filter bag length, bag mouth spring loop, and sewing thread. What factors affect the specifications of the bag filter? The size of the dust bag is related to the size of the dust cleaning pulse valve and the arrangement of the pulse valve. The diameter of common pulse industrial dust collectors is generally between 120mm and 152mm.
