Description
Technical field
The present invention relates to a kind of device of handling pernicious gas, particularly a kind of spin planet fluid bed that can be used for dust-removal and desulfurizing.
Background technology
The existing device of handling pernicious gas, the whirlwind fluidised form that is CN2083961U as Chinese utility model patent notification number purifies device for eliminating smoke and dust, be the fluidised form clarifier to be set on the top of the core pipe of common vertical cyclone dust collectors, and be provided with a grid and at least one deck the fluidisation ball with and static height on the core pipe, at the shower nozzle at core pipe top, the manhole door of weighing apparatus face, disclosure has all been done in the diameter of grid assembling, fluidisation ball and proportion requirement etc.This technical solution complex structure, the inconvenience maintenance particularly has higher specification requirement to core pipe and fluidisation ball portion.In addition, notification number is the tangential admission dust-removal and desulfurizing three phase fluidized bed of CN2220590Y, this fluid bed system is made of desulfurizing tower and Venturi tube, be furnished with eddy flow plate demister in the desulfurization tower body from top to bottom successively, washing absorbs the slurries spray equipment, filling ball, filler grid and spray cooling device, and the bottom has the buck outlet, Venturi tube is connected with the desulfurization tower body between described spray cooling device and buck outlet, and described Venturi tube is disclosed to be connected with tangential direction of desulfurization tower body and desulfurizing tower etc. between described buck outlet and direct-contact desuperheater.The document has been put down in writing employing tangential admission connected mode, and the centrifugal force that produces when relying on its gas to enter makes flue dust contact with the moisture film of cylinder inboard wall and reaches the dedusting purpose.Notification number is the spiral case air inlet dust-removal and desulfurizing three phase fluidized bed of CN 2431943Y, this fluid bed has disclosed same system and has been made of desulfurizing tower and Venturi tube, be furnished with eddy flow plate demister in the desulfurization tower body from top to bottom successively, washing absorbs the slurries spray equipment, filling ball, filler grid and spray cooling device, and the bottom has the buck outlet, the characteristics that Venturi tube is connected with the desulfurization tower body between described spray cooling device and buck outlet, wherein difference is that Venturi tube is led to desulfurizing tower with the spiral case intake method, and filling ball is the solid filling ball of foaming micropore.The document has been put down in writing the technical solution of further improving dust removing effects on the basis of aforementioned techniques scheme, but still complicated its intake resistance of structure, dedusting, desulfurized effect do not resolve fully, and the Venturi tube consumption that can increase electric power is set.In addition, also underway to the experimental study and the discussion work of auspicious streaming dust-removal and desulfurizing technology in addition.
The technical scheme of comprehensive above-mentioned disclosure, fluid bed all exist when air-flow changes, and can't ensure the optimal morphology of stream ball motion, cause the efficiency of dust collection instability; Yet people take to increase the carriage number of plies or flow the nodule number amount to reach stable efficiency of dust collection, like this, will certainly cause many chain links and contradictions such as SR increase, and the structure more complicated; Also fail to solve preferably the optimal morphology problem that the stream ball moves even if adopt the technical scheme of turbulent flow tower.
Summary of the invention
At above-mentioned situation, the object of the present invention is to provide a kind of not only simple in structure but also dust-removal and desulfurizing stabilised efficiency, but also have that water is few, the spin planet fluid bed of power consumptive province, easy to maintenance, air-flow wide accommodation.
For achieving the above object, a kind of spin planet fluid bed, comprise urceolus, be arranged at the supporting plate in the urceolus and be positioned at fluidisation ball and shower on the supporting plate, wherein supporting plate matches with outer tube inner wall, and the central authorities of this supporting plate connect all opening and the disjunctors of being provided with of an inner core and ring in the flow deflector of opening.
For implementation structure optimization, reach dust-removal and desulfurizing effect preferably, its further step also has:
The gradient of described flow deflector is an acute angle.
Described opening is a strip gab.
Described opening is the waveform opening.
Described opening is non-regular shape opening.
Described opening is that annular array is laid.
Described fluidisation ball is planetary and is arranged on the supporting plate in the circuit between the inside and outside tube.
Described shower is arranged at the ring week of inner core on the supporting plate.
Be provided with the desulfurization lubricating fluid in the described shower.(as nertralizers such as soap lye, alkalies)
Its supporting plate also can have another technical solution:
As supporting plate being made as upper and lower supporting plate, described mounting plate is the water conservancy diversion frame for stream ball-collecting rack, described bottom plate.
The present invention adopts so that opening and flow deflector to be set on the supporting plate, and be equipped with inner core, annular spray in conjunction with urceolus, hydrojet reaches the technical scheme that makes the stream ball that one annular spin planetary motion track be arranged, and has solved the jump that causes flowing ball because of variations in flow in the prior art scheme and has been the difficult problem that labile state has a strong impact on the dust-removal and desulfurizing effect.Make the following characteristics of tool of the present invention: 1) harmful exhaust is cut apart and surperficial turn by the planet of number laminarization ball in the circular orbit, adding the annular spray convection current ball that is provided with on the mounting plate sprays, make the heterogeneous spin that forms gas, water, ball in the circuit from moistening the interaction every trade star circulation of going forward side by side, as in spray liquid, adding soups such as desulfurizing agent, lubricant, then can carry out synchronized desulfuring, lubrication in the co-flow of gas in apparatus of the present invention, reach purifying and dedusting in spin and planetary motion; Desulfurization and dedusting is effective, and wherein desulfurized effect can reach more than 90%, efficiency of dust collection reaches 99.7%, dust exhausting concentration is less than 49mg/m
3As being used for the coal-fired boiler in power plant flue gas, institute's discharged flue gas is not emitted white cigarette, free from environmental pollution, meets the environmental protection new-standards such as thermal power plant's coal-burning boiler that China is using; 2) pernicious gas of being introduced by flow deflector has the stream ball of rule turn to carry out the lubricated interaction of annular planet with oriented in rotation in order, obtained omnibearing renewal after the phase mutual friction of its superficial layer of process and the turn, add the cocircuit top and also be provided with dehydrating functions such as demist plate, so not only desulfurization and dedusting is effective in the present invention, and dehydration, removing fog effect might as well, make the flue gas of discharge comparatively dry, its water capacity is below 3.5%; 3) SR of the present invention falls smallerly, is about 735Pa, and therefore power consumption is few; 4) apparatus of the present invention is simple and reasonable, and parts, especially consumable accessory are seldom, maintenance the time also need not shut down, manufacturing and easy for installation, obviously reduced equipment cost and operating cost, and broad prospect for its application is arranged.Be widely used in the processing or the recovery of industry dedusting, desulfurization and other pernicious gases such as boiler, cement, chemical industry, iron and steel, pharmacy, metallurgy.
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
