Description
Technical field
The present invention relates to the cutting of a kind of pipe tobacco and use ceramic cleaner, particularly relate to one and grow tobacco containing the Ceramic dust collector of spark dust-filtering in cutting process, this equipment also can be used for the dust process of the high-temperature flue gas such as boiler.
Background technology
In pipe tobacco cutting process, many tiny pipe tobacco dust can be produced, both contaminated environment, also can produce harm to human body, thus need to carry out purified treatment.Traditional dedusting technology, as moisture film wet dedusting, cyclone dust removal and electric precipitation, efficiency of dust collection is lower, has a lot of limitation, and cyclone dust collectors are very low to the removal efficiency being less than less than 5 μm dust, and electric precipitation requires that dust has large ratio resistance.
Bag-type dusting especially membrane bag filter dedusting has very high efficiency of dust collection, can reach more than 99.99% to the clearance that average grain diameter is 2.5 μm, but in pipe tobacco cutting process, pipe tobacco can produce Mars because of high-speed friction.These Mars can be adsorbed on surface of filter medium when filtering, and existing sack cleaner mostly is organic filter material, are easy to breakage occurs under the boiling hot burning of Mars.Existing organic filter material is when processing band Mars dust, and the life-span, lower than 2 months, needs frequently to change, and not only makes the maintenance of equipment very loaded down with trivial details, also significantly increases cost.Patent CN20447600U describes a kind of deduster that can be used for machining dedusting, but used be the organic filter material of low temperature, cutting etc. have Mars to produce operating mode under, be easy to damage filter material.
Because ceramic-film tube is that inorganic particle at high temperature sinters and forms, so can heatproof more than 500 DEG C, also can not be destroyed because of the attachment of Mars, thus can be greatly improved its service life.In addition, because ceramic-film tube has unsymmetric structure, the problem utilizing surface filtration technology to solve Air permenbility and dust rejection can not to get both, makes equipment have the advantage that gas treatment amount is large and dust rejection is high simultaneously.Ceramic-film tube is more and more applied in the purification of high-temperature gas, but have not been reported for the process with Mars dust in pipe tobacco cutting.
Patent CN202315565U discloses a kind of high-efficiency ceramic cyclone dust collectors, there is high temperature resistant, erosion-resisting feature, ceramic material adds the smoothness of device interior, contribute to the inside blockage problem improving dust, but its dust filtration efficiency only has 98%, be thus difficult to remove tiny and lighter particle.
Earthenware in existing Ceramic dust collector is monolayer alignment, and equipment filling area is little, and causes the waste in blowing device and cleaner space.Chinese invention patent CN203030134U describes a kind of Frequency Adjustable sound wave ashing refractory ceramics deduster, sound wave is utilized to improve cleaning efficiency, but common ceramic filter element is single structure, and pore passage structure is easy to blocked, filter pressure is caused to rise fast.Patent CN203694778U provides a kind of stratum granulosum porous ceramics deduster filtering PM2.5, but ceramic filter element adopts monolayer alignment, make the filling efficiency of deduster low, and use overall pulse in this patent, not only need to use large-scale venturi guiding device, raise device height, and jetting deashing less effective.
Summary of the invention
