What’s the function of dust collector

It separates the dust from the flue gas is called a dust collector or dust removal equipment. The role of the dust collector will be to filter out these dusts. For example, in coal mines, some coal powder will appear during construction. For construction workers, These dusts will have a great impact on their bodies, and may also explode. These dusts can be filtered out by the dust collector.

Vibrating bag dust collector and pulse dust collector are two commonly used dust collectors

Comprehensive Comparison of Mechanical Vibration Dust Collector and Pulse Reverse Dust Collector

1.Mechanical vibrating bag dust collector is generally used for working conditions where the air volume for dust removal is not large and the atmospheric emission requirements are not high. It is a more traditional method of dust removal. One time. Its advantages are: small footprint, simple production and installation. During the dust removal process, the dust sticking to the surface of the bag is shaken off by vibrating and sags by gravity.

2.Pulse back-blowing bag dust collector is used in the working condition with increased dust removal air volume and relatively high atmospheric emission requirements. It is the most widely used dust removal method at present. Use, the bag has a special skeleton support, the dust on the surface of the bag is back blown by compressed air, the intake pipe has a special venturi, a special back blowing channel, a pulse controller and a pulse control valve to control the back blowing time and beat , Dust sticking to the surface of the cloth bag is combined with gravity to fall down by blowing back. It has the advantages of high dust removal efficiency, obvious dust removal effect, and less dust emission from the atmosphere; the disadvantage is that the area is slightly larger and the cost is slightly higher.

3.The principle of the pulse reverse filter cartridge dust collector is the same as that of the pulse reverse bag filter, except that the filter material is the filter cartridge. The filter cartridge is pleated and has a skeleton, so it has a larger filtration area and a smaller volume , The overall cost is not much different from the pulse blowback bag filter. The advantages are: the volume and shape of the equipment are slightly smaller, and the transportation and installation are convenient. It is mostly used in the steel structure industry and workshops, grinding and dust removal industries. If it is used in the casting and forging industry, it needs to be equipped with a cyclone dust collector for primary filtration. The disadvantage is that the cost of replacing a single filter cartridge is slightly higher, but the overall price and the price of the pulse bag filter are moderate

3.Pulse cleaning cartridge filter and bag filter pulse cleaning principle, in that it is a cartridge filter material, the filter cartridge is due to the fold-shaped, with its own frame, so compared to the filter area, small overall cost and pulse cleaning bag filter is not very different. Advantages are: the volume of the device is slightly smaller form factor, easy to transport and install. Used for the steel industry and workshop, grinding dust and other industries, such as casting and forging industry uses front Cyclones need to be equipped with a preliminary filter. The disadvantages are: single filter cartridge replacement cost is slightly higher, but moderate overall price and pulse bag filter Price

Advantages of pulse Reverse Dust Collector

1. High dust removal efficiency: the pulse reverse blow type dust collector adopts the sub-room stop wind pulse spray dust cleaning technology, and the cleaning efficiency is higher
2.Improved the operating conditions of bag changing: the pulse back-blowing dust collector adopts the upper bag drawing method.After the skeleton is drawn out when the bag is changed, the dirty bag is put into the lower part of the box …
3.Good sealing: The box body is designed with airtightness, good sealing, and the door is made of excellent sealing materials.During the production process, it is detected by kerosene.

3. Reduced energy consumption for dust cleaning: Since the pulse-reverse-type dust collector adopts the sub-chamber air-stop pulse spraying for dust cleaning, the purpose of complete dust cleaning can be achieved by blowing once, so the dust cleaning cycle is prolonged and the energy consumption for dust cleaning is reduced ,

The long life of the filter bag: overhauling and replacing the bag can be carried out in separate rooms under the normal operating conditions of the system fan. The filter bag mouth adopts elastic expansion ring, which has good sealing performance, firm and reliable. The filter bag keel adopts polygonal shape, which reduces the friction between the bag and the keel, prolongs the life of the bag, and is convenient for unloading the bag.

Improved bag-changing operating conditions: the pulse backflushing dust collector adopts the upper bag-drawing method. After the bag is withdrawn, the dirty bag is put into the ash hopper at the bottom of the box and taken out through the manhole, which improves the bag-changing operating conditions.

Good airtightness: The airtight design of the box body, good airtightness, excellent sealing material for inspection doors, kerosene leak detection during production, low air leakage rate
