Technical scheme of the present invention is pressurizeed for the flue gas 16 that will contain dust and its bottom in filtered fluid 9 is transformed into a lot of very little bubbles 17, from the process that rises in the bottom of filtered fluid 9, run into the motion of bar at bubble 17 with the generation level, and run foul of each other, make its with filtered fluid 9 to contact the path longer and fully mix with filtered fluid 9.
Bubble 17 is provided with narrow meshed filtration from the process that rises in the bottom of described filtered fluid 9, repeatedly will constantly become big bubble splitting and become little bubble, and the surface area sum of all bubbles 17 increases.
On the liquid level of filtered fluid 9, apply a negative pressure that the flue gas 16 in the filtered fluid 9 is separated out easily.
Filtered fluid 9 can adopt the liquid of different chemical property according to the chemical composition of the flue gas 16 of being discharged, and it is harmless making after gas and its reaction.
The specific embodiment of technique scheme is:
Filtered fluid become contain in container, the method of employing air blast is pressed into flue gas 16 bottom of container from flue dust generation equipment smoke exhaust pipe 4 by pipeline, and adopt the structure of aperture that flue gas 16 is become a lot of very little bubbles 17 in the end of pipeline gas outlet, and in the process of the rising of bubble 17, utilize the structure of bar, make bubble 17 produce a horizontal motion again, and run foul of each other, make its with filtered fluid 9 to contact the path longer and fully mix with filtered fluid 9.Bubble 17 is in uphill process, and the minute bubbles set forms air pocket.In this process, on the above-mentioned bar a lot of very little through holes, force air pocket to refilter into minute bubbles, the surface area sum of all bubbles 17 increases.
Bubble contacts with more liquid in this process, makes the dust in the flue gas can fully dissolve in filtered fluid, and gas and filtered fluid fully carry out chemical reaction.Behind the aperture on the bar, the liquid level that bubble can continue to rise until arriving filtered fluid is separated out.
Because gas is subjected to bigger resistance in filtered fluid,, arrange in the air by chimney so must after gas is separated out, adopt blast apparatus that gas is extracted out.So require seal of vessel, otherwise, negative pressure can't be produced.
The type of the flue gas that production produced of all kinds of industrial and mining enterprises is inequality, so must adopt different filtered fluids according to the chemical property of flue gas.If flue gas is alkaline, then adopt acid filtered fluid; If flue gas is acid, then adopt alkaline filter liquid; If flue gas is neutral, then adopt clear water as filtered fluid.
The present invention further proposes the design of the specific product of implementation method: promptly adopt above-mentioned filtrating smoke dust method and the filtrating smoke dust device 3 made, be arranged in the soot emissions system 2, reservoir smoke-intake pipe 7 one ends are communicated with flue dust generation equipment smoke exhaust pipe 4, the other end feeds in the reservoir 11, the top connection of reservoir pipe 12 1 ends and reservoir 11, the other end is communicated with chimney 13, and described filtered fluid 9 places in the reservoir 11.
The smoke filtration method that the front is narrated, be to realize by following structure in this device: reservoir smoke-intake pipe 7 stretches into the bottom in pond in reservoir 11, its sprayer having many holes is the porous smoke evacuation shower nozzle 8 that is provided with a lot of apertures, establish the porous smoke evacuation plate 10 parallel with liquid level, that section is a plurality of " W " shapes continuously in the pond, be provided with a lot of apertures above it.Porous smoke evacuation shower nozzle 8 makes flue gas become minute bubbles, the porous of " W " shape smoke evacuation plate 10 plays the effect that stops bubble directly to rise continuously, and top aperture splits into minute bubbles with air pocket, after minute bubbles pass porous smoke evacuation plate 10, owing to be oblique, produce collision between mutually." W " ramp structure gas there is the effect of guiding, be unlikely to make bubble to stagnate and gather, influence filter effect.The shape size of porous smoke evacuation plate 10 should equal the shape size of reservoir 11 level cross-sectionns.
In order further to improve filter effect, porous smoke evacuation plate 10 can be for two-layer or more multi-layered, is parallel and parallel with the liquid level of filtered fluid between mutually certainly, makes above-mentioned filter process carry out repeatedly.
Because flue gas 16 self does not have the power of motion, and in filter process, be subjected to very big resistance, so all need being set in the front and back of reservoir 11, gas carries facility, the mode that the present invention takes is: be equipped with blower fan 5 and blower motor 6 on reservoir smoke-intake pipe 7 and the reservoir pipe 12, its fan direction of rotation flows to chimney 13 for making flue gas 16 from flue dust generation equipment smoke exhaust pipe 4.Reservoir 11 except that with above-mentioned two pipeline connected components, its whole box body is airtight, guarantees that in this way flue gas enters reservoir 11 and is malleation, utilizes negative pressure to separate out liquid, and extracts out outside the reservoir 11.
The present invention is in order further to improve filter effect, adopt the mode of a plurality of reservoir 11 series connection, be that reservoir 11 can and be series connection for two or more, be first reservoir 11 and reservoir smoke-intake pipe 7 UNICOMs, last reservoir 11 and reservoir pipe 12 UNICOMs, adopting reservoir to connect smoke pipe 15 between the reservoir 11 in order connects, be that reservoir connects an end of smoke pipe 15 and the top of a last reservoir 11 is connected, the other end stretches into the bottom of next reservoir 11, and its sprayer having many holes is the porous smoke evacuation shower nozzle 8 that is provided with a lot of apertures.Through multiple times of filtration, the poisonous and harmful element in the flue gas further descends.
The area sum of the aperture of porous smoke evacuation shower nozzle 8 or every block of porous smoke evacuation plate 10 can not be too small, and is excessive with the resistance that prevents to discharge fume, and damages blower fan 5 and blower motor 6.
With the same reason of front narration, after having increased reservoir, also to increase the power that flue gas is carried.Take following mode: reservoir connects on the smoke pipe 15 can be provided with blower fan 5 and blower motor 6, and its fan direction of rotation flows to chimney 13 for making flue gas 16 from flue dust generation equipment smoke exhaust pipe 4.
Because the variation of production technology, the flue gas that produces in producing sometimes contains dust or poisonous, or or not only contained dust but also poisonous; Sometimes be no dust and nontoxic.Flue gas carries out above-mentioned filtration and causes waste for no dust and when nontoxic.Consider this, the point, the present invention has taked following measure: flue dust generation equipment smoke exhaust pipe 4 and chimney 13 are connected for isometrical coaxial line, establish movable smoke baffle plate 14 between the two, movable smoke baffle plate 14 is detachable or rotates, when movable smoke baffle plate 14 insert its pipe in the installation site time, flue dust generation equipment smoke exhaust pipe 4 and chimney 13 are separated fully.When flue gas is to contain dust or poisonous, or had not only contained dust but also when poisonous, movable smoke baffle plate 14 is packed into, this filter works, and flue gas leads to filter and filters; Otherwise, open movable smoke baffle plate 14, flue dust generation equipment smoke exhaust pipe 4 and chimney 13 directly are communicated with, and nontoxic flue gas directly discharging enters atmosphere, and this filter is inoperative, has reduced the loss of power consumption and equipment.Movable smoke baffle plate 14 can be made two semicircles, becomes complete circle when closing, and constitutes every the cigarette state; When opening, two semicircles that form altogether vertically upward promptly constitute the state of natural draught system.
