The specific embodiment

As shown in Figure 1, the utility model smoke eliminator comprises atomizing filter and the water filtering device that is attached thereto, and the front end of atomizing filter communicates with flue.Described atomizing filter can be connected in series two or three mutually, and three atomizing filters shown in the figure are connected in series mutually with pipeline, and last atomizing filter connects water filtering device.

As Fig. 2, shown in Figure 3, the atomizing filter comprises atomizing filtration barrel body 6, water inlet pipe 1, sparge pipe 5 and rotary blade 12.The air inlet 7 of one end face of atomizing filtration barrel body 6 joins with flue, and the delivery port 8 on the side joins by the air inlet of pipeline and second atomizing filtration barrel body.Be provided with water inlet pipe 1 with air inlet 7 relative positions, the sparge pipe that is driven rotation at a high speed by transmission device is supported in the diaxon bearing 3, and an end of sparge pipe docks with water inlet pipe by spacer 2, and spacer 2 can make sparge pipe and water inlet pipe relatively rotate, and prevents to leak.The other end of sparge pipe 5 stretches in the atomizing filtration barrel body 6, is evenly equipped with aperture 11 stretching on this section tube wall of cylindrical shell, the sparge pipe end mouth of pipe sealing relative with air inlet.Described transmission device comprises runner 4, the centre bore of this runner and the sparge pipe tight fit that is driven by high-speed electric expreess locomotive.Rotary blade 12 places in the atomizing filtration barrel body 6, with sparge pipe 5 coaxial installations, one end face of rotary blade is fixedlyed connected with sparge pipe 5, and the other end is provided with the centre bore that is connected with air inlet 7, and the blade of arranging with the annular array rotation 13 is housed between both ends of the surface.Pipeline is provided with one group of adjustable damping plate 9 below the atomizing filtration barrel body delivery port 8, this adjustable damping plate 9 for upper and lower two be complementary with internal diameter of the pipeline, the thin plate composition of uniform apopore on it, be provided with handle at the thin plate edge, by turning handle the apopore on upper and lower two thin plates is misplaced, thereby regulate the size of its apopore, be used for regulating air-flow and water smoke flow velocity.This adjustable damping plate 9 can be provided with upper and lower two groups arranged side by side where necessary.

As shown in Figure 4, be provided with outlet pipe 10 in the duct wall bottom in adjustable damping plate 9 downstreams, the position of outlet pipe is lower than two adjacent atomizing filtration barrel bodies 6.

As shown in Figure 5, described water filtering device comprises water filtration tank body 16, is arranged at the water inlet 18 of water filtration tank base, is covered in the conical guard 17 of water inlet top and the water backflow overflow lip 14 that is arranged at the water filtration tank wall, in the terminal pipeline feeding water filtration tank body 16 that links to each other of atomizing filter, its pipeline opening is positioned at water backflow overflow lip 14 belows, is provided with up-small and down-big tubaeform filtering screen 15 between pipeline opening outer wall and water filtration inner tank wall.

Open all taps and supply water for water inlet, water inlet pipe, open each high-speed electric expreess locomotive simultaneously,, thereby make sparge pipe, the rotation of rotary blade synchronous high-speed by the driven by motor runner.The water of blowing water pipe aperture ejection is because centrifugal action, collide with sudden force with the blade on the rotary blade, be ground into a large amount of droplets, the thrust that the rotation feedwater of rotary blade simultaneously and smoke mixture one are initial, make the globule and flue gas quicken to clash into sudden force once more, droplet is pulverized once more, thereby formed water smoke with the adjustable damping plate 9 of bottom, and fully contact, exchange with toxic gas with flue dust, they can be dissolved in the water fully.Because the interior formed eddy current of atomizing filtration barrel body enters flue gas continually from flue tube, contact, dissolve again with water smoke.Simultaneously, discharge from the dislocation apopore of adjustable damping plate owing to contain the water smoke of flue dust and toxic gas, because the cross section increases suddenly, its flow velocity slows down suddenly, makes water smoke condense into waste water and also precipitates gradually, discharges from the outlet pipe 10 of duct bottom.Flue gas and a small amount of water smoke enter next atomizing filter to be continued to filter, contact, dissolving, the water spray haze of being discharged by last atomizing filter feeds in the water filtration tank body, the reverse contact of water of coming in bottom water inlet 18, micro-flue gas and toxic gas are further dissolved, pass through discharging of screen pack 15 then, water-fast particle is tackled in the water filtration tank body 16 of water filtering device with filtering screen 15 from water backflow overflow lip 14.The liquid and the micro-flue gas of discharging from water filtration tank body 16 top water backflow overflow lips 14 have reached national specified discharge standard substantially.Meanwhile, the heat that flue gas brings with carry out sufficient heat exchange through the formed globule of high-speed rotating impeller, water smoke, temperature is descended, part is discharged with outlet pipe, a little heat enters next atomizing filter with flue gas and a small amount of globule again and carries out heat exchange once more with the water of newly coming in, so that reaches normal temperature.

The waste water that places the outlet pipe 10 of duct bottom and the water backflow overflow lip 14 on the water filtration jar to be discharged, after the precipitation purification, can recycle for the water inlet pipe 1 of atomizing filter, the water inlet 18 of water filtration jar once more again, avoid water resource waste, cost-saved again.
