More specific technical solution further include:
The see-through air bells cap of high temperature resistant is equipped with movable plate, convenient for charging and the maintenance of coreless induction furnace, the see-through air bells cap of high temperature resistant
Lower end extend downwardly into the fire door lower end position of coreless induction furnace, can prevent flue dust from overflowing from coreless induction furnace side, more conducively recycle
Flue dust.
Further, cold-hot wind switch is connected with cold wind ingress pipe, by cold wind import inside cold-hot wind switch with
Heat exchange is carried out with the poisonous and harmful flue dust of high temperature of coreless induction furnace, reduces coreless induction furnace flue dust temperature.
Further, being transported to after the poisonous and harmful flue dust of coreless induction furnace high temperature is by the cooling of cold-hot wind switch by blower
Water spray system is sprayed.
Further, controllable sprinkler head is installed in water spray system, and water volume adjustable size, the installation of water spray system top
There is off-gas recovery processing unit, having concentration in off-gas recovery processing unit is 10% iodine absorbing liquid, the flue gas warp that is absorbed that treated
After crossing flue gas inspection dress detection qualification, it can be discharged into atmosphere.
Further, dust collector is accessed in water spray system bottom, solid-liquid separator is installed below dust collector, Gu
Dust is separated from water by liquid/gas separator, and dust is recycled with dust accumulator tank.
The invention has the advantages that
It realizes that coreless induction furnace generated poisonous and harmful flue dust in smelting metal all recycles, eliminates and contain 20~50mg/m3It is dense
The direct outlet of the flue dust of degree is eliminated a large amount of dust and is arranged to atmosphere, makes outstanding contributions for efforts at environmental protection；Process is short, operation is simple
It is single.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
Such as Fig. 1, the present embodiment is that the see-through air bells cap 2 of high temperature resistant covers on above coreless induction furnace, the see-through air bells cap of high temperature resistant
Lower end extend downwardly into the fire door lower end position of coreless induction furnace 1, the see-through air bells cap of high temperature resistant by hot wind collecting pipe 3 with it is cold and hot
Wind switch 4 connects；Cold-hot wind switch is connected with cold wind ingress pipe 5, and cold wind is imported inside cold-hot wind switch
Heat exchange is carried out with the poisonous and harmful flue dust of the high temperature of coreless induction furnace, reduces the poisonous and harmful flue dust temperature of coreless induction furnace high temperature, cold-hot wind
Switch is connect with blower 6；Blower is connect with water spray system 7 again, is transported to water spray system by blower and is sprayed；
It is connect at the top of water spray system with off-gas recovery processing unit 11, off-gas recovery processing unit is installed above water spray system,
