Abstract

The utility model provides an efficient sealing dedusting submerged arc furnace. The efficient sealing dedusting submerged arc furnace comprises a slag iron outlet, a smoke discharging pipe, a furnace body and a smoke hood, wherein the slag iron outlet is arranged on the side of the submerged arc furnace, the smoke discharging pipe is arranged on the upper portion of the submerged arc furnace, an electrode is inserted in the furnace body, and the smoke hood is provided with an electrode fixing sleeve and a blanking pipe. The efficient sealing dedusting submerged arc furnace is characterized in that the smoke hood is an arched hood, the lower edge of the arched hood is fixed at the top of the furnace body, a dust hood is arranged above the slag iron outlet, and the top of the dust hood is provided with a dust discharging pipe communicated with the smoke discharging pipe. The top of the submerged arc furnace and the sealing performance of the smoke hood are improved, plenty of generated smoke is effectively collected when slag iron is discharged, dedusting treatment is performed directly through the smoke discharging pipe, heat loss is reduced as far as possible, dedusting effect is improved, the working environment is improved, physical health of operators is protected, the pollution to the environment caused by the smoke is reduced, and the efficient sealing dedusting submerged arc furnace is favorable for energy saving, consumption reduction and emission reduction.

Description

Efficient sealed dedusting mineral hot furnace

Technical field

The utility model relates to a kind of mineral hot furnace, and especially a kind of mineral hot furnace of efficient sealed dedusting belongs to smelting equipment technical field.

Background technology

The existing mineral hot furnace for melting ilmenite concentrate, still exist petticoat pipe sealing not good, heat loss is serious, dust removing effects is poor, and the volume of smoke especially producing in the time of slag iron cannot be collected the problems such as eliminating, causes operating personnel often in high temperature, high dust working environment, both operating personnel had been affected healthy, cause again flue dust to the staining of environment, affect the heat utilization efficiency of mineral hot furnace simultaneously, be unfavorable for saving energy and reduce the cost.Therefore be necessary prior art to be improved.

Summary of the invention

The purpose of this utility model is to provide a kind of tight, good dedusting effect, mineral hot furnace that heat utilization efficiency is high of sealing.

The utility model completes by following technical proposal: a kind of efficient sealed dedusting mineral hot furnace, comprise that sidepiece establishes slag iron outlet, smoke exhaust pipe is established on top, the body of heater of inner intercalative electrode, and which is provided with electrode fixed cover, the petticoat pipe of tremie pipe, it is characterized in that petticoat pipe is made as arch cover, and the lower edge of arch cover is fixed on body of heater top, and above the outlet of slag iron, dust gathering arrester is set, this dust gathering arrester top is provided with the dust flue being communicated with smoke exhaust pipe, so that arch cover and body of heater top are connected as a single entity and complete sealing, the flue dust simultaneously producing during by slag iron by the draft of smoke exhaust pipe is through dust gathering arrester, dust flue, smoke exhaust pipe is evacuated to dedusting in deduster, the pollution that the flue dust producing while effectively preventing slag iron causes working environment.

Described body of heater comprises furnace shell and interior high temperature resistant furnace wall thereof, and this is high temperature resistant, and furnace wall is refractory masses, and furnace shell is made as the hollow sandwich between inner casing, shell and inside and outside shell, and shell is connected with inlet tube and outlet tube, to send into cooling water to hollow sandwich.

Described arch cover comprises cover body and interior refractory masses thereof, and cover body is made as the hollow sandwich between inner cover, outer cover and inside and outside cover, and outer cover is connected with inlet tube and outlet tube, to send into cooling water to hollow sandwich.

Described upper of furnace body is interval with smashes material mouthful, each is smash material mouthful both sides and is respectively equipped with door pillar, this door pillar is the hollow door pillar with inlet tube and outlet tube on it, on door pillar, be hinged with the shutter door being formed by refractory masses and the outer field steel plate of internal layer, smash material to open the door as required, the melting of closing the door, and guarantee sealing and insulation.

The utlity model has following advantages and effect: adopt such scheme; improve the sealing property of mineral hot furnace top and petticoat pipe; in the time of slag iron, effectively collect the volume of smoke producing simultaneously; and directly send dust removal process by smoke exhaust pipe, and reduce as far as possible heat loss, improve dust removing effects; improve working environment; protection operating personnel are healthy, reduce flue dust to the staining of environment, and are conducive to energy-conservation, consumption reduction, reduce discharging.
