Description
Technical field
The utility model relates to gas cleaning dedusting technology field, particularly relates to a kind of metal-silicon furnace flue gas ash removal integrating device.
Background technology
At present in metal-silicon furnace melting continuously process, furnace charge batches adds, interruption is come out of the stove, the waste gas that electric furnace produces mainly comprises: silica and carbonaceous reductant are under the high temperature action of electric furnace, there is reduction reaction, the gases such as a large amount of Si, CO, CO2 under high temperature pressure through the bed of material, because cooling and oxidation reaction Si gas condense into rapidly tiny micro-silicon grain furnace charge is surperficial, the material particles and the gas that confuse other just constitute flue gas, and its flue dust character is as follows:
Smoke components
| Composition | N2 | CO2 | SO2 | O2 |
| Percent by volume | 76-78% | 2-3% | ≤0.02 | 19.5-20.5% |
Cigarette flue dust composition
| Composition | SiO2 | FeO | CaO | MgO | Al2O3 | C |
| Percentage by weight | 83-93% | 0.5-3% | 0.4-1% | 1.0% | 0.2-0.5% | 3-8% |
Smoke granularity:
| Composition | ≤1.0μm | 1.0-10μm | ≥10μm |
| Percentage by weight | 60% | 30% | 10% |
Comprehensive upper table is presented at the part that metal-silicon furnace flue dust is less than 1 μm due to grit and occupies significant proportion, so can not governance for reaching standard with general dedusting technology.During the semiclosed cover of smelting commercial silicon employing, flue-gas temperature controls at about 500 DEG C.The control of flue-gas temperature mainly relies on the size that enters air capacity outside adjustment petticoat pipe and cooler to carry out heat exchange.Due to flue-gas temperature reduce time, the viscosity of dust increases greatly, therefore the flue-gas temperature entering dedusting filtering bag should control at 160 DEG C ~ 220 DEG C as best.
Utility model content
For overcoming the defect for small high-temperature dust process in prior art, the purpose of this utility model is to provide a kind of metal-silicon furnace flue gas ash removal integrating device, and its technical scheme specifically adopted is as follows:
A kind of metal-silicon furnace flue gas ash removal integrating device, it comprises: flue, expansion joint, water cold sleeve, explosion-proof valve, support of pipelines, access door, block clearing mouth, cyclone separator, cold blast sliding valve, main air blower, suction fan, sack cleaner, bypass valve, aiutage, encryption tank, abhiseca separator, encryption roots blower, described flue is an iron pipe, its pipeline is provided with described expansion joint, water cold sleeve, explosion-proof valve, support of pipelines, access door and have described block clearing mouth; Described cyclone separator air inlet is connected with described flue end port, and gas outlet is connected with the air inlet of described main air blower; Add described cold blast sliding valve at described main air blower air inlet place and have air port and be connected with described suction fan; Described sack cleaner is connected with the outlet pipe of described main air blower; The outlet pipe end of described main air blower is provided with described bypass valve, aiutage; Described encryption tank top is provided with described abhiseca separator, at the bottom of tank, is provided with described encryption roots blower.
According to above-mentioned design of the present utility model, described flue has two roads, and its conduit entrance corresponds respectively to two metal-silicon furnace flue dust mouths.
According to above-mentioned design of the present utility model, described sack cleaner air inlet valve and back suction air-valve adopt disc type air-valve.
Advantage of the present utility model and usefulness are: to compensate in prior art for fine and deficiency that is high-temperature dust poor processing effect, have the following advantages:
1, from ash bucket dust inlet opposite inhale cleaning dust, avoid ash bucket blocking, eliminate blanking device and shake motor, decreasing power consumption.
2, opposite inhale cleaning dust and Geldart-D particle share a Fans, save a suction fan, reduce operating cost.
3, suction fan impeller longer service life, because by the silica flour of blower fan and gas through cyclone dust removal, silica flour concentration is less, less to draught fan impeller abrasion.
4, in dust collector ash hopper, dust back suction is to encryption tank ciphered compressed, and unit volume soot density strengthens so that packed transport, saves freight.
