Description
Technical field
The present invention relates to cleaner, particularly a kind of Combined dust-cleaning apparatus.
Background technology
Along with industrial expansion, industrial dust pollution is more and more subject to people's attention, particularly the dust of micron-class superfine particle, not only can cause climate change, more can produce harm to health, such as PM2.5, not only can bring haze weather, produces visual pollution, and be very easily inhaled into human lung, injury lung organ, therefore, the removal of ultra-fine grain dust more and more pay close attention to by people.
In prior art, cyclone dust collectors are mainly used in the pre-dedusting of high concentrate dust and feed separation and recovery, grit to be separated by means of centrifugal force and to trap in wall by cyclone dust collectors from air-flow, and relend and help Action of Gravity Field to make grit fall into ash bucket, it belongs to middle effect deduster; Have structure simple, easily manufactured, operating flexibility is large, investment and maintenance cost low, for trapping, be separated more than 10 μm dust efficiency higher, but not ideal enough for the dust removing effects of less than 3 μm dust, be difficult to meet existing environment protection emission requirement.
During the industrial dusty gas that solid particle granularity is little for removing, solids content is large, often adopting the processing mode of multistage cyclone series connection or whirlwind series connection cloth bag for reaching separation requirement, all there is the shortcomings such as equipment investment is large, floor space is large, system pressure drop is high in these two kinds of processing modes.
As Chinese patent ZL01243742.5 discloses a kind of circulating flow type circulation dust removing system, it is made up of two stage cyclone deduster, column splitter and circulating fan, the particle of less than 3 μm can be removed, efficiency of dust collection can reach 98%, but this dust pelletizing system exist fluid rotate in splitter insufficient, enlarge-effect is remarkable, there is intercycle blower fan, equipment takes up an area the drawbacks such as large and complicated operation.
As adopted whirlwind to connect the processing mode of cloth bag, sack cleaner utilizes media filtration dust, and its advantage is that efficiency of dust collection is high, and shortcoming is the bulky of sack cleaner, exist equipment investment high, take up an area the shortcomings such as large and system pressure drop is high; Sack cleaner changes cloth bag costly, and when cloth bag is many, judge that the broken bag position time is long, the internals such as steel ring skeleton easily damage, and complicated operation during replacing internals, wastes time and energy; When dust content is larger, the service life of back-blowing frequency influence sack cleaner need be increased.Therefore, provide that a kind of equipment investment is few, floor space is little, the Combined dust-cleaning apparatus of simple to operate and long service life, significant.
Summary of the invention
In order to solve, cleaner of the prior art investment is large, floor space large, complicated operation and the short problem of service life of equipment, the invention provides a kind of Combined dust-cleaning apparatus.
In order to solve the problems of the technologies described above, the present invention by the following technical solutions:
A kind of Combined dust-cleaning apparatus comprises cyclone dust collectors, horizontal segregation section again and bag-type dust bag, wherein, horizontal segregation section again comprises cylindrical shell, and wall place, cartridge inlet port limit arranges pipe I, wall place, cartridge outlet end limit arranges pipe II, and cartridge outlet end arranges center discharge pipe; Cyclone entrance is tangentially connected with cartridge inlet by pipe I, and the entrance of sack cleaner is tangentially connected with cartridge outlet by pipe II.
As preferably, can also arrange air guide in the cylindrical shell of horizontal segregation section again, the High Rotation Speed that air guide is conducive to dusty gas advances.
Cyclone entrance is tangentially connected with cartridge inlet by pipe I, dusty gas can be made tangentially to enter horizontal segregation section again from cyclone dust collectors, this tangential mode of entrance can make fluid-flow rate faster, dusty gas is advanced in the rotation of horizontal segregation section again along wall high speed, and continue to assemble to barrel under centrifugal action, purified gas is discharged by center discharge pipe, and remaining fine dust and a small amount of gas are compiled in pipe II and finally enter sack cleaner; The entrance of sack cleaner is tangentially connected with cartridge outlet by pipe II, fine dust air-flow can be made tangentially to enter extraction pipe and enter in sack cleaner at a high speed to rotate, the centrifugal action that rotary motion produces is got rid of fine dust to wall, when fine dust is by wall filtrate, ultrafine dust, by detention, makes dusty gas be purified.Compare with prior art, the gas flow entered in sack cleaner significantly reduces, and the volume of corresponding sack cleaner reduces, and equipment investment reduces, and operating cost and system pressure drop are also less; The minimizing of sack cleaner volume makes the replacing of device interior component become simple, extends the service life of sack cleaner to a great extent; Enter sack cleaner from the fine dust air-flow of horizontal segregation section again extraction to collect, ensure that discharge index, purified gas major part is discharged by center discharge pipe, reduces the dustiness of Exhaust Gas, improves efficiency of dust collection.
The horizontal structure of segregation section is again simple, and easily manufactured, operating flexibility is large, investment and maintenance cost low, gentle for dust stream can be separated, horizontal segregation section more provided by the invention and tangential in design improve efficiency of dust collection to a great extent, and finally have received good dust removing effects.
Combination Design like this, the volume processing sack cleaner when identical air quantity is little, and structure is simple, practical cheap; Be convenient to multiple stage parallel connection during process Wind Volume use, efficiency resistance is unaffected.
The inner barrel that as preferably, in Combined dust-cleaning apparatus provided by the invention, cyclone dust collectors comprise outer cylinder body, be connected with outer cylinder body concentric by bracing frame and the conic tube being arranged on outer cylinder body lower end; Outer cylinder body bottom arranges the inlet tube tangentially entering inner barrel, and conic tube lower end arranges ash releasing tube.The larger-diameter grit in dusty gas is removed in the effect of cyclone dust collectors, and larger-diameter grit is separated in cyclone dust collectors to get off.
Combined dust-cleaning apparatus floor space provided by the invention and little, the maintenance cost of investment and pressure drop is little, long service life; The efficiency of dust collection of package unit can reach more than 99%, improves the efficiency of dust collection of device, have received good dust removing effects; Current environment protection emission requirement can be met, the dedusting of the industrial discharge gas such as Industrial Stoves, boiler, flue gas can be widely used in.
