Description
Technical field
The utility model relates to and is used for a kind of inward flow filtration-type dust-filtering equipment that the Wind Volume ash-laden gas purifies in a kind of cleaner, particularly field of Environment Protection.
Background technology
Along with the raising of industrial development and people's environmental protection consciousness, various dedusting technologies are developed by people, and various cleaners also just arise at the historic moment.
The performance of cleaner is mainly manifested in filters and deashing two aspects.With dust dedusting technology existing level, filter effect being reached or be better than environmental protection standard is not difficult matter, with the dedusting draught control of cleaner relative difficult then in predetermined limits.Make a general survey of the poor problem of operational effect that occurs in the existing cleaner dust pelletizing system, the overwhelming majority causes the resistance rising relevant with ash-removal effect is bad, therefore " deashing " is the deciding factor that is related to the dust pelletizing system success or failure.Along with operating mode continues, be collected at dust on the cleaner filter surfaces with cumulative, the corresponding running resistance that will increase equipment.In order to guarantee the normal operation of system, the cleaner resistance should be maintained within a certain range, and surpasses this limited range and namely should carry out deashing.The quality of ash-removal effect is concerning resistance, efficient, the service life of filter material and the various indexs such as economical operation benefit of cleaner of cleaner.
According to latest national standards, the basic demand of deduster deashing is the dust that peels off quickly and evenly deposition from filter, can keep again certain primary dusts layer simultaneously, and not damage filter and consume less power.Cleaner commonly used mainly contains mechanical rapping cleaning dust sack cleaner, back-blowing sack cleaner, pulse blowing bag type dust precipitator at present.Mechanical rapping cleaning dust sack cleaner simple structure, reliable, but the deashing effect is inhomogeneous, can only allow lower filtration velocity, and deashing often easily damages filter, destruction primary dusts layer.The back-blowing sack cleaner is in whole filter overdraught distribution uniform, vibrates inviolent, less to the filter damage, but a little less than the deashing effect, allow filtration velocity lower.Pulse blowing bag type dust precipitator is a kind of high-effective dust-removing cleaning equipment, has that ash-removal effect is good, purification efficiency is high, processing is large-minded, filter life is long, maintenance load is little, safe and reliable to operation, automaticity advantages of higher.Because above plurality of advantages, pulse blowing bag type dust precipitator is present general, the most efficient filter deduster in the world.But pulse blowing bag type dust precipitator of the prior art all needs for filter arranges a supporting bag cage, and this bag cage needs periodic inspection and replacing, uses inconvenience, and is with high costs.
