With the filter condition progresses, dust bag piled on, when the resistance of the device reaches the limit of resistance value (usually set 1500Pa), by cleaning the differential pressure control device according to the set value or cleaning time the set value is automatically shut off valve after a room, according to the set program opens electronically controlled pulse valve, stop the wind were blowing, blowing with compressed air and instantly increase the inner polyethylene bag pressure will be on the bag and shake off the dust (Even if the fine dust can also stick more thoroughly cleaning) to the ash bucket, ash discharged from the institution. The dust on the staff of the respiratory tract and eyes around will cause great harm, because the wood contains creosote dust containing carcinogenic substances strong, prolonged inhalation, suffering from bronchitis will be part of the workers, asthma and lung emphysema and other occupational diseases, and even cancer; in addition, suspended dust will increase the production of abnormal wear of equipment, shorten the life of equipment, increasing maintenance costs; one of the most serious point of flammable materials, wood dust is the most dangerous, can lead to fire. Wooden doors factory doors of factories precipitator dust composed mainly of the box, the box, hopper, inlet manifold all, stand bag and blowing device, discharging device and other components. Dust and gas from the precipitator inlet manifold are entering the sub-compartment hopper and the hopper at diversion diversion devices, large dust particles are separated, directly into the hopper, and the fine dust into uniform Central housing adsorbed in the outer surface of the bag, the bag into the clean gas through the housing, and by the various off-line valves and the exhaust pipe into the atmosphere. Doors of factories dedicated central feature of a pulse dust, wood dust concentrations for large features, the use of the gradient flow channel design, to ensure uniform distribution of air flow, so do all the cleaning air bag evenly injection and filtration, increase bag The overall life expectancy; 2, for the hydrophilic characteristics of wood dust, there is dust in the hopper frame arch bridge leads to the phenomenon of blocking material may occur in dust hopper design vibrator, assisted cleaning, reduce artificial cleaning work. During the operation of timber doors of factories cutting, sheet metal surface finish, sanding, trimming, etc. will generate a lot sawdust and wood. Our dedication to its roughly divided into the following several years of environmental protection in accordance with industry practitioners: Various planer, shavings produced by milling cutting, wood chips and wood fiber, etc. is a large wood dust; various sawing wood, drilling cutting resulting a medium-sized wood dust; flour produced by cutting a variety of sanding machine type genus fine wood dust. Maintenance method for woodworking dust collector? Woodworking dust collector maintenance each year to be recalibrated once all the pressure sensors and pulse cleaning air compressor overhaul, planned downtime must check all woodworking dust collector valves, flower plate, inspection door, bag, pulse cleaning control devices and pipes. In addition, every year to remove random from each of the twelve sub-chamber for laboratory analysis dust bag, bag life to helping the speculation, consider whether you need to replace the dust bag in advance. In order to ensure proper operation of woodworking dust collector, and possible damage to the subject in the past to identify the existing filter, dust removal system to deal with the situation daily checks. Check the contents include: air conditioner pressure setting is appropriate, the supply of air bag pressure is accurate. Visually inspect the cleaning cycle within the operation of the valve. Check pulse duration and the pause time between pulses. Proofreading parade DCS monitoring and record the woodworking dust collector operating parameters, such as pressure on the intake and exhaust temperature, total pressure drop and drop each compartment.
