Description
Technical field the utility model belongs to environmental technology field, relates to a kind of iron alloy electric furnace smoke eliminator.
The background technology The ferroalloy industry is one of important industry of country, also is simultaneously to cause one of environmental pollution, industrial production sector that public hazards are serious.In the production of ferroalloy enterprise, electric furnace is all producing a large amount of dust, waste gas all the time, has not only polluted the working environment of workshop, simultaneously atmospheric environment is caused great harm.Because the dust size that iron alloy electric furnace produces is thinner, and certain viscosity is arranged, and adopts the cyclone dust collectors dust removing effects not good at present; Use the sack cleaner dedusting, operation beginning effect is better, but along with collected dust layer thickening on the cloth bag, be difficult to deashing again, and sack cleaner is difficult to operation.Adopt traditional electric cleaner to administer the flue dust that iron alloy electric furnace produces, efficiency of dust collection is low, does not reach the discharge standard of national requirements.Therefore, the dust that iron alloy electric furnace is produced is administered and is still belonged to unsolved technical barrier at home, how to adopt modern dedusting technology to purify the dust that iron alloy electric furnace produces, and protecting and improving environment is the problem that needs to be resolved hurrily at present.
The summary of the invention the purpose of this utility model is for purifying dust, waste gas and the solution problem of environmental pollution that the production of The ferroalloy industry electric furnace produces, a kind of iron alloy electric furnace smoke eliminator being provided.
The utility model iron alloy electric furnace smoke eliminator content Description:
The utility model iron alloy electric furnace smoke eliminator, it is characterized in that: suspended hood is set above electric furnace, interconnect with pipeline between suspended hood, humidification modifying device, electric cleaner, the blower fan, glance coal coacervation device is installed on the trunk line, and humidification modifying device and electric cleaner are combined;
Electric cleaner is that preposition pre-charged device is set before electric field, is made up of pre-charged negative electrode and pre-charged anode, belongs to an independently power supply area, and electric cleaner is formed the two-region electric field;
The humidification modifying device is the structure of drum, and its middle and upper part is provided with nozzle, and with vaporific ejection, it is aerosol type humidification modifying device that evaporimeter is set in the humidification modifying device to water under high pressure from nozzle.
The utility model iron alloy electric furnace smoke eliminator belongs to the environmental protection cleaner, and it adopts glance coal coacervation device that the atomic glance coal coacervation in the flue dust Central Asia is increased slightly, forms the condensate than macroparticle.With the humidification modifying device flue dust is carried out modifier treatment, to improve the ratio resistance of flue dust.Carry out gas solid separation with electric cleaner, the valency dust that has that in the flue dust atmosphere is polluted is reclaimed, purified gas enters atmosphere through the blower fan chimney, realizes qualified discharge, is a kind of more satisfactory, safe and reliable environmental protection cleaner.The utility model not only can be administered the pollution of iron alloy electric furnace flue dust to atmosphere effectively, and its recovery has the valency dust to can be enterprise certain extra earning is arranged.

The specific embodiment
The utility model iron alloy electric furnace smoke eliminator is achieved in that below in conjunction with accompanying drawing and specifies.See Fig. 1, the iron alloy electric furnace smoke eliminator is with glance coal coacervation device 7, humidification modifying device 2, electric cleaner 3 is combined, above electric furnace 1, suspended hood is set, interconnect with the pipeline 6 that has flange between suspended hood and humidification modifying device 2, electric cleaner 3, the blower fan 4, glance coal coacervation device 7 is installed on the trunk line 6.Because the flue dust that iron alloy electric furnace produces is more higher than resistance value, directly enters electric cleaner and does not reach dust removing effects, adds humidification modifying device 2 before electric cleaner 3, can effectively reduce the ratio resistance value of dust.During the work of iron alloy electric furnace smoke eliminator, the flue dust that electric furnace 1 produces through humidification modifying device 2 carry out humidification modified after, the character of flue dust is gathered dust with electric cleaner 3 with regard to relatively being fit to, efficiency of dust collection is improved greatly, flue dust is after electric cleaner 3 dedustings, and flue gas up to standard enters chimney 5 through pipeline 6 and is discharged in the atmosphere.
See Fig. 2, the electric cleaner 3 that adopts in the iron alloy electric furnace smoke eliminator is electric cleaners that preposition pre-charged device 8 is set before electric field.Preposition pre-charged device 8 is made up of pre-charged negative electrode 9 and pre-charged anode 10, belongs to an independently power supply area.When preposition pre-charged device 8 is worked, when dust-contained airflow passes through pre-electric charge field, because the collision of ion, with the diffusion of ion, make dust charged, the charged dust of small part is under the effect of electric field force, to pre-charged anode 10 motions, on pre-charged anode 10, most of charged dust enters in single district electric field of preposition pre-charged device 8 back with air-flow, is collected by electric cleaner 3.The electric cleaner 3 that has preposition pre-charged device 8 can be regarded as the two-region electric field, and is charged and gather dust and carry out in two steps, and the charging area back is the combinations of a plurality of single districts electric field, and single district's electric-field charge and gathering dust carries out simultaneously.Front end at electric cleaner 3 is provided with pre-charged device 8, can make the dust more higher than resistance value charged more abundant, has alleviated the burden of single district electric field of electric cleaner 3 back, thereby has reached the purpose that improves efficiency of dust collection.
See Fig. 3, humidification modifying device 2 is an aerosol type humidification modifying device, is the structure of a drum, and its middle and upper part is provided with nozzle 11, and evaporimeter 12 is set in humidification modifying device 2.Water under high pressure from nozzle 11 with vaporific ejection, the tiny globule is through evaporimeter 12 evaporations, and carry out heat exchange with hot flue gas by humidification modifying device 2, droplet is evaporated fully become steam, both increased the humidity of flue gas, reduced the temperature of flue gas, the ratio resistance value of flue dust is reduced, the operate as normal that helps electric cleaner 3, the dust-collecting efficiency of raising electric cleaner 3.
When containing stickum such as pitch in the flue gas that iron alloy electric furnace produces, glance coal coacervation device 7 can be set on the pipeline before the humidification modifying device 2, glance coal coacervation device 7 with extraordinary composition such as the pitch in the flue dust and molecule cohesion, adhere to so that catch, and make the glance coal surface of coacervating large particle wrap up one deck dust again, make it to cement on the electrode, can effectively avoid the corona wire hypertrophy like this, and the dust rapping to being collected on the positive plate is more prone to, thereby guarantees dust removing effects.The utility model iron alloy electric furnace smoke eliminator model machine seals the test of industrial group Co., Ltd Jiaozhuo king, has obtained desirable dust removing effects, and concentration of emission is 74.4mg/m after testing
