The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: this spray tower structure for spraying and dedusting, it is included in the primary dust removing chamber that is provided with at interval in the gas wash tower 1 from bottom to top, two-stage dust removal chamber and 3-stage dust-removal chamber, be provided with the air-flow whirligig in the gas wash tower 1 above the 3-stage dust-removal chamber, described air-flow whirligig comprises the inner ring body 2 and outer ring body 3 that connects together, be fixed with blade 4 between the madial wall of the lateral wall of inner ring body 2 and outer ring body 3, make adjacent two blades 4, inner ring body 2 forms gas channel with outer ring body 3, the axis of described gas channel length direction and inner ring body 2 or outer ring body 3 is antarafacial and intersects, and all gas channels are clockwise or counterclockwise arranges, and is provided with dividing plate 5 with its endoporus shutoff at the madial wall of inner ring body 3.
Described primary dust removing chamber is included in the fume pipe 6 that connects on the gas wash tower 1, the port of export inside of fume pipe 6 is provided with guide pad 7, on gas wash tower 1 inwall corresponding above the port of export of fume pipe 6, the water fender 8 of width greater than fume pipe 6 ports of export is set, water fender 8 sets up some spray heads 9 by downward-sloping to close gas wash tower 1 axis one end away from gas wash tower 1 axis one end in the gas wash tower 1 above water fender 8.
Described two-stage dust removal chamber is included in the fixing support underframe 10 of gas wash tower 1 inwall, is coated with corrosion resistant stratum reticulare 11 on support underframe 10, lays dedusting carrier ball 12 on corrosion resistant stratum reticulare 11, and gas wash tower 1 internal frame above dedusting carrier ball 12 is provided with some spray heads 9.
Described 3-stage dust-removal chamber is included in the fixing support underframe 10 of gas wash tower 1 inwall, on support underframe 10, be coated with corrosion resistant stratum reticulare 11, on corrosion resistant stratum reticulare 11, lay dedusting carrier ball 12, be coated with spongy filter course 13 on dedusting carrier ball 12, gas wash tower 1 internal frame above spongy filter course 13 is provided with some spray heads 9.
Described fume pipe 6 internal diameters are increased to its outlet side internal diameter gradually by its inlet end, described guide pad 7 external diameters are increased to the end near gas wash tower 1 wall gradually by the end away from gas wash tower 1 wall, described fume pipe 6 all is coniform with guide pad 7, described fume pipe 6 is consistent with the tapering of guide pad 7, and distance equates between guide pad 7 outside wall surface and fume pipe 6 internal faces.
Described dedusting carrier ball 12 is included in the passage of offering on the installing plate 121 122, all be fixed with some blades 123 in installing plate 121 upper and lower surfaces, and blade 123 roots of same installing plate 121 upper and lower surfaces are and shift to install, and the axis of passage 122 and blade 123 have the intersection point on blade 123.
Installing plate 121 is laminar flat board with blade 123, and installing plate 121 and blade 123 outer contours formation spheroid, and installing plate 121 is along the weft direction setting of described spheroid, and blade 123 is along the warp direction setting of described spheroid.
Described spray head 9 is included in and connects the spiral helicine atomizing piece 92 that 91 bottoms, termination connect, described atomizing piece 92 is also dwindled to its lower end extension gradually by its upper end, form ejiction opening between the upper and lower two-layer atomizing piece 92 of in the vertical direction, in connecting termination 91, has water stream channel 93, described atomizing piece 92 is wound in water stream channel 93 bottoms, and described water stream channel 93 is the taper cavity that seamlessly transits.91 outer walls are processed with screw thread in described connection termination, have nut 94 on the 91 bottom outer walls of connection termination, and the outline formation tapering of described atomizing piece 92 is 20～30 ° a cone.
Ash-laden gas rises in gas wash tower 1, and primary dust removing chamber, two-stage dust removal chamber and 3-stage dust-removal chamber spray a large amount of water from top to bottom.Because fume pipe 6 internal diameters are increased to its outlet side internal diameter gradually by its inlet end, guide pad 7 external diameters are increased to the end near gas wash tower 1 wall gradually by the end away from gas wash tower 1 wall, so, the ash-laden gas that sprays from fume pipe 6 outlet sides is directed to and is divergent shape after piece 7 leads, by behind the water fender 8 lower surfaces retaining, produce static pressure again, the ash-laden gas air-flow will evenly slowly rise from lower to upper, can not produce bounce-back, avoid the port of export of fume pipe 6 to produce backwater phenomenon.And after the basipetal big flow spray droplet of ejection is kept off by water fender 8 upper surfaces in the spray head 9, also avoided the backwater phenomenon of the port of export of fume pipe 6.
The moistening dust that is not removed rises to wet dedusting rotating vane of the present invention, the flue gas that contains moistening dust enters from the inlet end of gas channel, because the axis of gas channel length direction and inner ring body 2 or outer ring body 3 is antarafacial and intersects, be provided with dividing plate 5 at the madial wall of inner ring body 2 with its endoporus shutoff, make sectional area reduce, the ash-laden gas wind speed increases, ash-laden gas produces centrifugal force through behind the gas channel, moistening dust is got rid of to gas wash tower 1 inwall, assemble the back and flow to the pond from top to bottom along gas wash tower 1 inwall, clean gas is arranged on the outlet side by gas channel.
And the dedusting carrier ball places the corrosion resistant stratum reticulare 11 on the support underframe 10 that laterally sets up in the gas wash tower 1, feeds ash-laden gas in the gas wash tower 1 of support underframe 10 belows, in the gas wash tower 1 of support underframe 10 tops the spray head 9 of lasting water spray downwards is set.Ash-laden gas rises by the passage 122 of dedusting carrier ball 12, dust contacts with the sidewall of blade 123 humidities, dust in the ash-laden gas promptly sticks on the sidewall of blade 123, and the moist dust that the downward water that continues spray head 9 ejections of water spray will stick to blade 123 sidewalls sweeps away, by 122 times rows of passage, realize self-cleaning function, make dedusting carrier ball 12 can not stop up.
Because the countless passages of offering on the installing plate 121 of dedusting carrier ball 12 122, can avoid the disturbance in the ash-laden gas uphill process, make and to beat more on the sidewall of blade 123, be adsorbed on the sidewall of blade 123 humidities through the dust in the ash-laden gas of passage 122.
During use, the connection termination 91 of spray head 9 is fixed on the end of shower, water stream channel 93 is the taper cavity that seamlessly transits, owing to there has not been the attachment point of plaster in the water stream channel 93, so water stream channel 93 can not accumulate plaster, thereby avoided the generation of water stream channel 93 blockage, atomize and will be punched in atomizing piece 93 from the water stream channel 92 interior water that spray, atomizing effect is better, atomized water is opened along being the directional divergence that is similar to 60 ° with water stream channel 92, it is pipe external spiral of the present invention that the present invention's realization has the pipe inside spin of technology, makes spout stop up never.
