Smoke inlet is higher than the base plate 0.5-2.0 of clean room rice according to the tonnage size of boiler, and the diameter of smoke inlet is a 0.5-2 rice.
The diameter of orlop umbrella cover is the 70-90% of clean room's internal diameter, orlop umbrella cover separable flue gas entrance height 0.8-2 rice, and the spacing of each umbrella cover is a 0.5-2 rice, the circular cone drift angle of each umbrella cover equates, is the 120-170 degree.
Water spout is apart from the top 0.5-2 rice of the superiors' umbrella cover.
There is resistance cigarette screw at 0.5-1 rice, water spout top, and resistance cigarette screw has 3-20 blade, and the diameter of resistance cigarette screw is the 60-80% of clean room's internal diameter.
Resistance 0.5-2 rice, cigarette screw top is clean room's top cover, and clean room's top cover is conical, and the circular cone drift angle of clean room's top cover circular cone drift angle and umbrella cover equates that the center of clean room's top cover is an exhaust opening, and the diameter of exhaust opening is the 10-30% of clean room's internal diameter.
Be placed with sulfur elimination in the sedimentation basin, sulfur elimination is lime, caustic soda or soda ash.
During use, the smoke inlet with boiler induced-draft fan exhaust outlet access smoke purifying equipment makes flue gas all get into the clean room, under the effect of blower fan; Make flue dust directly impact umbrella covers at different levels, contact with the cascade that falls on the umbrella cover, water is evoked; Produce the spray and countless water droplet and water smoke, in the clean room, form the multilayer water curtain, increased flue gas and aqueous vapor time of contact; Grit is with the continuous motion of water curtain, and the separation that repeatedly atomizes purifies smokeshade; Thicker grit is repeatedly the tackling of cascade, water curtain, aqueous vapor, collide, under the effect of cohesion, ionization, drop to the bottom, clean room; Get into sedimentation basin, purified gas inserts chimney by the vaporizer exhaust opening and discharges.Current in the clean room get into sedimentation basin through the bottom of clean room, are extracted out by water pump after the clarification to recycle again, and the waste residue of sedimentation basin bottom is discharged by slag notch.
Advantage of the present invention is:
⑴ purification efficiency is high, good airproof performance, and noiseless is stable, non-secondary pollution.
⑵ operating cost is low, and resistance is little, and water consumption, electricity consumption are few, cleans, easy to maintenance, simple to operate the equipment devoid of risk.
⑶ be placed with sulfur elimination in the sedimentation basin, can reduce the acidity of waste residue, recirculated water, make cleaned air passes more fresh and clean.
⑷ clean room adopts all steel manufacturing, exquisite appearance, and acid and alkali resistance, antiseptic property is strong, and is safe and reliable, long service life, the clean room handles air quantity can reach 1200-160000m
3/ h can make tens kinds of series.
⑸ easy for installation, and floor space is few.
