Described spray head 4 is included in and connects the spiral helicine atomizing piece 42 that 41 bottoms, termination connect, described atomizing piece 42 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 42 of in the vertical direction, in connecting termination 41, has water stream channel 43, described atomizing piece 42 is wound in water stream channel 43 bottoms, it is characterized in that: described water stream channel 43 is the taper cavity that seamlessly transits.
41 outer walls are processed with screw thread in described connection termination, have nut 44 on the 41 bottom outer walls of connection termination, and the outline formation tapering of described atomizing piece 42 is 20～30 ° a cone.
Be fixed with the some support underframe 15 that are provided with at interval at gas wash tower 1 inwall, on support underframe 15, be coated with corrosion resistant stratum reticulare 12, on corrosion resistant stratum reticulare 12, lay dedusting carrier ball 8, gas wash tower 1 internal frame above dedusting carrier ball 8 is provided with some spray heads 4, described dedusting carrier ball 83 is included in the passage of offering on the installing plate 81 82, all be fixed with some blades 83 in installing plate 81 upper and lower surfaces, and blade 83 roots of same installing plate 81 upper and lower surfaces are and shift to install, and the axis of passage 82 and blade 83 have the intersection point on blade 83.
Installing plate 81 is laminar flat board with blade 83, and installing plate 81 and blade 83 outer contours formation spheroid, and installing plate 81 is along the weft direction setting of described spheroid, and blade 83 is along the warp direction setting of described spheroid.
On the dedusting carrier ball of placing on the support underframe 15 that is positioned at top layer 8, be coated with spongy filter course 9, gas wash tower 1 inwall above spongy filter course 9 has set up air-flow whirligig 10, described air-flow whirligig 10 comprises the inner ring body 101 and outer ring body 102 that connects together, be fixed with blade 103 between the madial wall of the lateral wall of inner ring body 101 and outer ring body 102, make adjacent two blades 103, inner ring body 101 forms gas channel with outer ring body 102, the axis of described gas channel length direction and inner ring body 101 or outer ring body 102 is antarafacial and intersects, and all gas channels are clockwise or counterclockwise arranges, and is provided with dividing plate 104 with its endoporus shutoff at the madial wall of inner ring body 101.
Ash-laden gas enters in the gas wash tower 1 and rising from fume pipe 2, and the spray head 4 in the gas wash tower 1 sprays a large amount of water from top to bottom.Because fume pipe 2 internal diameters are increased to its outlet side internal diameter gradually by its inlet end, guide pad 14 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 2 outlet sides is directed to and is divergent shape after piece 7 leads, by behind the water fender 3 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 2 to produce backwater phenomenon.And after the basipetal big flow spray droplet of ejection is kept off by water fender 3 upper surfaces in the spray head 4, also avoided the backwater phenomenon of the port of export of fume pipe 2.
And dedusting carrier ball 8 places the corrosion resistant stratum reticulare 12 on the support underframe 15 that laterally sets up in the gas wash tower 1, feeds ash-laden gas in the gas wash tower 1 of support underframe 15 belows, in the gas wash tower 1 of support underframe 15 tops the spray head 4 of lasting water spray downwards is set.Ash-laden gas rises by the passage 82 of dedusting carrier ball 8, dust contacts with the sidewall of blade 83 humidities, dust in the ash-laden gas promptly sticks on the sidewall of blade 83, and the moist dust that the downward water that continues spray head 4 ejections of water spray will stick to blade 83 sidewalls sweeps away, by 82 times rows of passage, realize self-cleaning function, make dedusting carrier ball 8 can not stop up.
Because the countless passages of offering on the installing plate 81 of dedusting carrier ball 8 82, can avoid the disturbance in the ash-laden gas uphill process, make and to beat more on the sidewall of blade 83, be adsorbed on the sidewall of blade 83 humidities through the dust in the ash-laden gas of passage 82.
The moistening dust that is not removed rises to air-flow whirligig 10, 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 102 or outer ring body 103 is antarafacial and intersects, be provided with dividing plate 105 at the madial wall of inner ring body 102 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.
During use, the connection termination 41 of spray head 4 is fixed on the end of shower, water stream channel 43 is the taper cavity that seamlessly transits, owing to there has not been the attachment point of plaster in the water stream channel 43, so water stream channel 43 can not accumulate plaster, thereby avoided the generation of water stream channel 43 blockage, atomize and will be punched in atomizing piece 42 from the water stream channel 43 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 43, 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.
During use, on the pool wall of dirt water reception tank 52, gas wash tower is installed, 1 sprays a large amount of water from top to bottom in the gas wash tower, this shower water enters dust adhesion in the ash-laden gas and flushing in the dust-containing water reception tank 52, when the dust-containing water in the dust-containing water reception tank 52 gathers certain depth, dust-containing water enters in the dust-containing water sedimentation basin 53 by the water stream channel of offering on the dividing plate 51 between dust-containing water reception tank 52 and the dust-containing water sedimentation basin 53 54, when the dust-containing water in the dust-containing water sedimentation basin 53 gathered certain depth, dust-containing water entered in the next dust-containing water sedimentation basin 53 by the water stream channel of offering on the dividing plate 51 between the two dust-containing water sedimentation basins 53 54.Because being, the water stream channel of offering on adjacent two demarcation strips 51 54 shifts to install, each water stream channel 54 exit end face is to demarcation strip 51, do not allow water stream channel 51 be aligned with each other, make the water route of dust-containing water increase, water velocity reduces, when reducing the current disturbance settled dust is stirred once again, quicken the precipitation of the dust in the dust-containing water, make that the dust sedimentation effect in the dust-containing water is good.
On dust-containing water sedimentation basin 53 pool walls, be provided with water pump interface 55, make shower water to reuse like this away from dust-containing water reception tank 52, the conserve water resource, but in use, water pump interface 55 needs to install screen pack.
As everyone knows, the general industrial flue dust all is weakly acidic, so after shower water carries out the dedusting of industrial fumes in gas wash tower 1, recirculated water in circulating sedimentation tank 5 all is weakly acidic, weakly acidic recirculated water is fed in the hardening and tempering reservoir 6 of the present invention, see through permeable gland layer 62 back and modified weak base piece layer 61 reaction, reacted water is alkalescent water, this alkalescent water continued to extract out and backwater to circulating sedimentation tank 5, saved water resource, avoided secondary pollution, the alkalescent water after modified is to having better cleaning performance attached to the faintly acid dust on the Wet-way dust-collector.
