Abstract
The utility model relates to a dust remover for steelmaking by an electric furnace, belonging to an air purifying and dust-removing device. The upper face of the electric furnace is covered with a trap whose upper end is connected with an air inlet duct of a Venturi dust remover through an air duct, an air outlet duct of the Venturi dust remover is connected with an air inlet duct of a granulite dust remover whose air outlet duct is communicated with a chimney through a blower, water inlet pipes of the Venturi dust remover and the granulite dust remover are respectively connected with a water pump, and water outlet pipes are respectively connected with a settling tank. The wet method has obvious effect on the dust removal of the steelmaking by the electric furnace.
Description
The utility model belongs to air cleaning cleaner class.
During electric furnace steel making, flue dust fills the air, and workman's operating environment is very abominable.The seventies once adopted bag-type dust collector.Because the raw material of electric furnace steel making mainly adopts wastes of iron and steel, wherein impurity is more, cooling fluid, used oil, wiper etc. are arranged, make purifier that stifled bag, sticking bag phenomenon often take place, cause reentrainment of dust when putting ash again, maintenance difficult, complicated operation are only changed one of cloth bag, and just need more than 120,000 yuan every year.The kind complexity of flue gas promptly has dust, flying dust, soot, oxidation abrasive grit, lime particle, unburnt oil droplet, also has carbon dioxide gas, carbon monoxide gas, oxygen, nitrogen, water vapour and a spot of nitrogen oxide etc.
The granularity scope of dust is bigger, and is as follows by analysis:
Less than 3 microns account for 18%;
3~11 microns account for 64%;
11~25 microns account for 11%;
Greater than 25 microns account for 7%.
Because many, the complicated component of flue dust kind, particle are trickle, bring certain degree of difficulty to the improvement of electric furnace dust.Venturi scrubber, back taper granite duster are the reasonable hydrofilters of present effect, have been applied at large in a lot of fields such as chemical industry, but all have been to use separately in use.
The purpose of this utility model is: provide that a kind of electric stove dust is effective, the electric furnace steel making Wet-way dust-collector.
Technical measures of the present utility model are: based on by venturi scrubber, back taper granite duster; On electric furnace, be covered with the trap of a cone cap shape, the trap upper end is connected with the air inlet duct of venturi scrubber by the air channel, the exhaust passage of venturi scrubber is connected with the air inlet duct of granite duster, and the exhaust passage of granite duster communicates with chimney by air-introduced machine; The water inlet pipe of venturi scrubber and granite duster is connected with the delivery port of water pump respectively, and outlet pipe is connected with sedimentation basin respectively.
Dust arrester of the present utility model, owing to utilized venturi scrubber and back taper granite duster, dedusting has tangible good effect to electric furnace steel making.
Accompanying drawing is a structural representation of the present utility model.
Drawing explanation and embodiment are described below: 1 is the trap 1 that covers on the cone cap shape above the electric furnace among the figure, trap 1 is connected by the air inlet duct of tracheae with venturi scrubber 2, the exhaust passage of venturi scrubber 2 is connected with the air inlet duct of granite duster 3, and the exhaust passage of granite duster 3 is connected with chimney 5 by air-introduced machine 4; The water inlet pipe of venturi scrubber 2 and granite duster 3 is connected with the outlet pipe of water pump 8 respectively, and outlet pipe is connected with sedimentation basin 6 respectively.After the buck that accompanies dust entered in the sedimentation basin 6, at the bottom of the dust sedimentation basin, clear water entered the clear water reserviors 7 from top, and the water in the clear water reserviors 7 is pumped in two dedusters 2 and 3 by water pump 8 again and gives a dinner of welcome.The process that the dust of electric furnace is cleaned is: electric furnace dust is caught after storage 1 collection, through venturi scrubber 2 first class purifications, the cigarette G﹠W fully contacts, the part dust is cleaned, flue gas enters in the back taper granite duster 3 by double purification again then, gas after processed is discharged through chimney 5, the dust buck that contains that flows out enters in the sedimentation basin 6, after purifying, precipitation enters in the clear water reserviors 7, by water pump 8 clear water is delivered in venturi and granite duster 2 and 3 again and to be recycled, water system forms a closed circulation process.
Claims (1)
1, a kind of electric furnace steel making dust arrester is made up of venturi scrubber, back taper granite duster, it is characterized in that:
