Bag filter dust removal efficiency is related with many factors, but mainly depends on the filter. Bag filter dust collector is a synthetic fiber, natural fiber or glass fiber woven fabric or felt. According to the needs of the cloth or felt sewn into a cylinder or flat-shaped bag. According to the flue gas properties, select suitable application conditions of media. Usually, the temperature of the flue gas is lower than 120 DEG C, demand media with acid resistance and durability of the cases, often choose polyester cloth and polyester needled felt; in dealing with high temperature fume ( < 250 degrees C ), mainly uses the graphitization of glass cloth; in some special cases, selection of carbon fiber and other media. In need of coal stone condition also need explosion proof antistatic treatment, the dust bag bag must choose the static-free silk fabric.
Pulse bag dust collector of single ( 2 ) operation of bag dust filter in the control of flue gas through the filter speed ( called the filtration speed ) is very important. General admission filter speed is 0.5 2m / min, for more than 0.1µ m particulate efficiency can reach more than 99%, equipment resistance loss of approximately 980 - I470Pa.
Editor this paragraph of JDMC series pulse long bag dust collector
Bag dust collector is subdivided into more variety, today I will introduce a kind of
Product brief introduction
JDMC series pulse long bag dust collector is the company engineering and technical personnel in the injection pulse ( jet pulse ) except for bag dust collector
Based on the technology of dust, and to meet the wind volume of flue gas purification needs of low pressure pulse bag dust collector. It has not only than the sail cloth bag dust remover deashing ability, high dust removal efficiency, emission concentration is low, but also has stable and reliable, low gas consumption, covers an area of small features, particularly suitable for processing large amount of flue gas . JDMC series low-voltage long bag pulse filter in the world has been widely used, in foreign countries also has a large number of use, promotion, and can be widely used in cement, metallurgy, petrochemical, building materials, food, machinery, electric power, carbon black, garbage, industrial furnace high temperature dust gas purification and dust-shaped materials recovery. This product is integrated sectional reverse blow and pulse cleaning dust remover has the advantages of two types, overcame sectional reverse blow ash strength is insufficient and the general pulse cleaning dust attached such shortcomings, the cleaning efficiency, injection frequency is greatly reduced. The use of the product drowned pulse valve, reducing the blowing air pressure and energy consumption of equipment in operation, prolongs the service life of the valve bag filter, pulse, comprehensive technical performance in improving.
Performance characteristics
The novel design, the air intake structure, coarse particles of a high temperature falls into the ash hopper directly, effectively protects the filter bag. Use of long bag, under the same processing power equipment covers an area of small, more convenient for the transformation of the old factory. Use divided chamber off-line cleaning, high efficiency, two times less dust adsorption, and effectively reducing the energy consumption of the equipment, the filter bag with a pulse valve fatigue degree is reduced accordingly, increase the filter and valve life, reduce the number of equipment operation and maintenance costs. The maintenance for bag can not stop system fan, the normal operation of the system under the conditions of divided chamber. The bag mouth adopts a spring tensioning structure, convenient disassembly and assembly, good sealing performance. The box body through the gas tightness design, and kerosene leak detection, maximum extent possible to reduce air leakage. The whole device by the PLC machine control, automatic cleaning, unloading, automatic temperature control and temperature n. There are many include a variety of dust removal equipment please visit:
Editor this paragraph the main factors affect the life
Effects of dust bag using the main factors of service life of the bag is prolonged life matters needing attention:
Dust bag jam
The bag is blocked, so that the resistance can be increased, by the differential pressure gauge readings increased performance. The bag plug is caused by wear, perforation, bag off phenomenon. The cause of blockage caused by dust bag, press table check and repair. General to take the following measures : 1 temporarily the dust bag, in order to eliminate clogging; partial or total replacement of the bag; the adjustment of the mounting and operating conditions. To prevent dust bag plugging measures
The phenomenon of examination contents and measures
Wet dust collector bag box section water leakage eliminating water leakage, drying, repeated cleaning
Dust damp identifying causes of elimination of causes, repair
Bag insufficient tension adjustment, repair method of hanging
Identifying the causes of lower blocking bag adjustment, repair
Bag mounting bad installation method adjustment, repair
Ash cleaning in 1, hopper is sealed
In 2, the cleaning mechanism of fault
In 3, the reverse blowing volume
In 4, a spray pressure of insufficient adjustment, repair
Identifying the cause of change of bag bag contraction
Filtration rate too high air volume adjustment
Dust filter bag.
Bag shape and bag installation method and mechanism determines the bag easily damaged position, and can check and repair. But mainly consists of the following causes bag breakage, such as occurrence breakage phenomenon can refer to the following table are examined: Reason Reasons measures
Dust cleaning cycle is too long to adjust, shorten the aging identification and elimination of the causes
Cleaning time adjustment, shorten the bag because of heat hardens the identification and elimination of the causes
Insufficient tension adjustment, strengthen burn bag to study bag material
The bag is too slack adjustment leakage dust identification and elimination of the causes
Bag mounting bad adjustment, strengthening high filter speed adjustment to reduce
Bag of aging
Mainly because of the following reasons caused by, be cause investigation, take measures to eliminate and replace the filter bag. 1, because of abnormal high temperature and hardening contraction; 2, with acid, alkali or organic solvent vapor exposure response; 3, and water reaction. 4, filter cloth is hung too loose or too tight, too easy to dust, too easy to pull bad. In 5, the new technology of old bags should not be mixed, to avoid damaging the time different effects of dust removal equipment normal work. 6, replace the bag, first with compressed air blowing net, and then check whether the holes, holes for replacement after repair. As dust covered cloth bag, water washing, drying for replacement.
　　布袋除尘器,工作机理是含尘烟气通过过滤材料,尘粒被过滤下来,过滤材料捕集粗粒粉尘主要靠惯性碰撞作用,捕集细粒粉尘主要靠扩散和筛分作用,滤料的粉尘层也有一定的过滤作用.
