GMC pulse jet bag filter has the following features:
1 Each row of filter bags is cleaned, the kinetic energy of the cleaning is large, the distribution of kinetic energy of the cleaning ash is uniform, the cleaning of ash is thorough, the operation resistance of the filter is low, and the resistance is ≤ 1200Pa.
2 The length of the filter bag is up to 8m, and the ratio of length to diameter is large. The dust collector has a small volume, a small footprint, and a light weight. The weight of the GMC pulse jet bag dryer dust collector is half the weight of the same air volume counter-blow bag filter.
3 When the dust is removed, a relatively small amount of high-pressure gas source is used to induce the filtered high-temperature clean gas around the nozzle to form a dedusting air flow, cleaning the filter bag, minimizing the introduction of cold air into the dust collector, and improving the resistance of the filter. Dew condensation performance.
4 can be used off-line cleaning or online cleaning methods. Offline cleaning can achieve online maintenance and change bags without stopping the machine.
(5) Adoption of air intake and external filtration method for sedimentation pre-collecting dust uniform air device reduces the abrasion of dust to the equipment and filter media, reduces the load of the filter bag, and also allows the exhaust gas to evenly distribute the different positions of the filter bag, so that the dust filter can Treat high concentrations of dusty exhaust gas.
GMC pulse jet bag filter can be selected according to the dust characteristics of the dryer. The domestic filter material can ensure that the filtration speed is about 1.0m/min, and the dust emission concentration is ≤50mg/Nm3. The imported high quality filter material can guarantee The filtration speed is about 1.2m/min, and the dust emission concentration is ≤10mg/Nm3.
GMC Dryer Pulse Jet Bag Dust Collector Anti-condensation and Anti-wear Measures
GMC Dryer Pulse Jet Bag Dust Collector has taken a series of measures in material selection, structural design and processing technology.
High-pressure pulse jet cleaning technology anti-condensation and eliminate dust on the bag's wear advantage. The high-pressure pulse jet cleaning uses a small amount of compressed air to induce more filtered clean hot gas cleaning to improve the anti-condensation performance of the equipment; the external filtration method allows the gas passing through the bag mouth to be filtered. Clean gas eliminates the wear of dust on the bag mouth.
The pre-dust collection effect of the precipitating and precipitating dust uniform wind device reduces the filter bag filter load and the wear of the coarse dust particles on the equipment and the filter bag. The function of precipitating and collecting dust air ducts is to evenly distribute the unfiltered dust-containing gas into the baghouses horizontally into the dust collector so as to ensure even resistance of each bag room. After the dust-laden gas enters the air duct, due to the rapid drop of the gas velocity and the obstruction of the special device on the common wind plate, there is a pre-settling process before the dust is filtered. Part of the dust, especially coarse dust particles, is not filtered before the filter bag Has fallen into the hopper, reducing wear on other parts of the equipment and filter bags.
According to different dust characteristics, choose a more suitable high-performance anti-condensation filter. Only when the system is abnormal, the exhaust gas temperature of the dryer will exceed 120°C. The pulse jet cleaning can provide enough clean energy. Combined with the over-temperature alarm and protection measures of the control system, the choice of filter material is larger. Filtration media is not the only choice. When selecting the filter media, factors such as anti-condensation and air-blanket ratio should be considered. Many processed normal, medium and high-temperature filter media are available for selection.
Take internal corrosion and wear resistance measures. Pre-harvesting dust ducts are made of wear-resistant material in the wind deflector device. The inside of the dust collector and the bag cage are sprayed with a high-temperature resistant anti-corrosive paint after being de-rusted.
Strict equipment processing technology, so that the equipment leakage to a minimum, in order to control the dust collection system leakage rate of 2% or less, the dust collector can be used to lock the air discharge valve can use electric or pneumatic double valve.
The appearance of insulation layer of dust collector is good.
Dryer dust collector application example
A cement plant steel slag dryer system adopts a rotary dryer with a specification of Ф2.4m×18m. The material adopts steel slag and the processing air volume is 40000m3/h. Use effect: dust collector resistance <1000Pa, emission concentration <50mg/Nm3.
The GMC pulse jet bag filter can handle the high concentration of exhaust gas to ensure the simplification and low resistance of the dust removal system under the premise of primary dust removal.
The pulse jet bag filter is more cost-effective, lighter in weight, lighter in size, less in annual operating costs, and has a much higher dust removal efficiency, lower equipment resistance, and a lower current in the exhaust fan at the end of the filter. A substantial reduction.
Effect of Pulse Jet Bag Dust Collector
The use of GMC pulse jet bag filter can reduce the exhaust gas emission concentration from 100mg/Nm3 using conventional dust removal equipment to 50mg/Nm3 or less without increasing investment or even saving investment.
The use of GMC Pulse Jet Bag Dust Collector expands the scope of use of filter media, allows the exhaust gas treatment of the dryer to select the best filter media according to the characteristics of the exhaust gas and dust, changing the effect of the traditional bag filter in different working conditions. With the large current situation, the performance-cost ratio of the dust collector system is greatly increased.
After the implementation of the “Emission Standard for Air Pollutants in the Cement Industry†(GB4915-2004), the GMC Pulse Jet Bag Dust Collector is the replacement product of the dryer bag filter.
