As shown in Figure 1, existing roller slag handling principle is: liquid warm sludge by slag ladle by traveling crane loading hopper 12 tops to roller slag disposal device, cylinder entirety starts rotation by the bull gear of transmission mechanism 17, flow guiding disc 11 and cylinder reverse rotation, thereby make liquid warm sludge enter smoothly cylinder inner core, delayed startup water injector 13, a large amount of cooling waters enter cylinder, liquid warm sludge is cooling at direct shower water, the steel ball 15 rolling push the water tank of cooling fragmentation and cylinder urceolus cooling etc. triple cooling under, liquid warm sludge and piece slag are lowered the temperature rapidly, granulation, from the castor bar that is 70 ~ 100mm by gap in inner core, enter urceolus, copy at urceolus under the effect of slag plate 14, granulation bits and part water enter chain mat machine 18 by going out funnel 16, send into stockyard.
The steam of discharging in existing roller slag disposal device directly by chimney discharged in the air, through environmental protection flue dust detect, find dustiness reach 1000mg/Nm
3, considerably beyond national standard.Rear trial increases spray equipment at chimney, to reduce the discharge capacity of chimney dust.As shown in Figure 2, existing spray equipment comprises spray inlet channel 3 and spray head assembly 4; The volume of smoke that roller slag disposal device 1 gives off is discharged through spray inlet channel 3 is sprayed water dedusting by spray head assembly 4 after by chimney 2, after this device operation is used, effect is unsatisfactory, the steam producing after water spray can not arranged chimney substantially, but around cylinder, fill the air in factory building, cause great impact to the maintenance of safety in production and equipment.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of steel-making roller slag and processes the tower dust arrester of discharge multi-stage spray, this dust arrester by spraying and dedusting after remaining flue gas dewater by eddy flow dehydrator again, simple structure, resistance are less, easy to operate, smoke emissioning pollution is realized to purification, guaranteed steel-making roller slag processing steady production.
The present invention is achieved in that the tower dust arrester of a kind of steel-making roller slag processing discharge multi-stage spray, chimney is three vertical-shaped pipes and two S shape bend pipes that swan neck forms, the 3rd vertical-shaped tube opening of S shape bend pipe is upwards as exhaust outlet, the air inlet of chimney is opened on the sidewall of the first vertical-shaped pipe, one-level drainage arrangement is equipped with in the bottom of described the first vertical-shaped pipe, in the first vertical-shaped pipe, spray head assembly is housed, described spray head assembly is connected with outside spray inlet channel; In described the second vertical-shaped pipe, dehydrator device is housed, described dehydrator device below is provided with Municipal secondary effluent device, in the pipeline between the second vertical-shaped pipe and exhaust outlet, blower fan is housed.
Described dehydrator device is eddy flow dehydrator.
Described the second vertical-shaped pipe connects the arm that catchments, and described Municipal secondary effluent device is arranged on the arm bottom of catchmenting, and described assembling is in the second swan neck.
Described Municipal secondary effluent device is arranged on the second swan neck bottom, and described assembling is in the 3rd vertical-shaped pipe.
The present invention makes steel and forms vaporific space by spray head assembly when roller slag is processed the tower dust arrester processing of discharge multi-stage spray ash-laden gas, in the time of vaporific space that ash-laden gas forms by spray, because of the collision between the two of grit and water droplet, the effect of combination, the particle of cohesion is settled down to spray column bottom thereupon, discharges by drainage arrangement; Remaining flue gas by discharging chimney by blower fan after the dehydration of eddy flow dehydrator, guarantees that dust content reaches discharge standard again, and smoke emissioning pollution has been realized to purification, has guaranteed steel-making roller slag processing steady production; Use and show through reality, the dust content that this device discharges after processing is less than 50mg/Nm
3, reach the national standard of discharge.
