The utility model discloses an air cooler for use in waste gas treater of ore heating electric furnace, mainly comprising an air cooler. The air cooler is communicated with a bag-type dust remover through an air-out pipe which is provided with a cold air inlet pipe provided with a valve. The utility model has the advantages that the air cooler can be used for effectively reducing the temperature of the high-temperature gas generated from the ore heating electric furnace to make the purifying recovery device effectively process the gas.
Description
Technical field
The utility model relates to the emission-control equipment of a kind of use on ore-smelting electric furnace, refers more particularly to the air cooling equipment in this device.
Background technology
Ore-smelting electric furnace is widely used in ferroalloy works, and dust content is higher in the waste gas that ore-smelting electric furnace produced, and 90% is SiO in the waste gas
2, also contain SO
2, Cl
2, NO
x, pernicious gas such as CO, its waste gas has higher recycling and is worth, through measuring and calculating, 1 ton of ferrosilicon of every production, can from waste gas, reclaim about 200～250 kilograms SILICA FUME dirt, therefore, directly enter this waste gas in the atmosphere, both environment is caused severe contamination, caused wasting of useful resources again.The temperature of the flue gas that ore-smelting electric furnace produced is all very high, generally about 450～550 ℃, and therefore must be to just purifying recycling behind this flue gas cool-down.
Summary of the invention
At the problems referred to above, the utility model will provide the air cooling equipment in a kind of ore-smelting electric furnace emission-control equipment that can effectively reduce the ore-smelting electric furnace EGT.
The technical solution adopted in the utility model is: the air cooling equipment in the described ore-smelting electric furnace emission-control equipment mainly comprises: air cooler, and air cooler is connected with sack cleaner by wind pipe; Be characterized in: also be provided with the cold wind air inlet pipe on wind pipe, the cold wind air inlet pipe is provided with valve.。
Mechanical air cooler recited above is indirect mechanical air cooler.
Sack cleaner recited above is a locellus blowing bag-type pulse dust collector.
The utility model further technical scheme is: also be provided with temperature sensor on wind pipe.
The utility model has the advantages that: the temperature of the high-temperature flue gas that can reduce ore-smelting electric furnace effectively and produced makes that purifying reclaimer can handle effectively to flue gas.
Description of drawings
Fig. 1 is the structural principle schematic diagram of the concrete a kind of embodiment that uses of air cooling equipment described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments technical scheme described in the utility model and operation principle thereof and advantage are further described.
As shown in Figure 1, in actual use, the emission-control equipment of ore-smelting electric furnace is main comprising generally: air inlet pipe 2, air inlet pipe 2 is connected with the air inlet of air cooler 3, the air outlet of air cooler 3 is connected by the air inlet of wind pipe 14 with sack cleaner 7, the air outlet of sack cleaner 7 is connected by the air inlet of induced duct 9 with air-introduced machine 11, and the air outlet of air-introduced machine 11 is connected with discharge flue 10; Also be provided with cold wind air inlet pipe 5 on wind pipe 14, cold wind air inlet pipe 5 is provided with valve 6.
In the present embodiment, described air cooler 3 is indirect mechanical air coolers, its structure is basic identical with indirect mechanical air cooler commonly used, its operation principle is: high-temperature flue gas is flowed through and is arranged in the interior tube bank of housing, with axial flow blower cold air is pressed in the housing, outside restraining, transversal flow is carried out in tube bank, and with the tube bank in hot-air carry out heat exchange, high-temperature flue gas in the tube bank is cooled to required temperature, is provided with six axial flow blowers 4 in the present embodiment altogether; The quantity of axial flow blower can be set in actual use, as required; Bottom at indirect mechanical air cooler 3 also is provided with unloading valve 15.
Described sack cleaner 7 is locellus blowing bag-type pulse dust collectors, and is basic identical with blowing bag-type pulse dust collector structure commonly used, also is provided with pulse valve 8 at its top, also is provided with unloading valve 12 in its bottom; In the present embodiment, be provided with six locellus blowing bag-type pulse dust collectors altogether, in actual use, the quantity of locellus blowing bag-type pulse dust collector can be set as required also.
The operation principle of above-mentioned emission-control equipment is: the high-temperature flue gas that is produced when one, ore-smelting electric furnace is worked enters into indirect mechanical air cooler 3 through air inlet pipe 2, in the present embodiment, temperature sensor 1 is installed on air inlet pipe 2, like this, control device can be controlled the quantity of the axial flow blower 4 of needs unlatching according to the temperature conditions of high-temperature flue gas in the pipeline, with the air quantity that regulating shaft flow fan 4 is sent, reach the purpose of control temperature.Two, enter into locellus blowing bag-type pulse dust collector 7 through indirect mechanical air cooler 3 cooled smoke by wind pipe 14, the version that goes out on advancing under adopting in the deduster and the project organization of inlet box and air inlet pipe, the Mars of carrying secretly in the flue gas is extinguished rapidly also can tentatively remove big dust particle with the protection filtrate, reduce the wear rate of filtrate, it is more reasonable that each chamber air-flow of deduster is distributed; The filter bag of deduster adopts beautiful this high temperature composite filtering material of the resistant to elevated temperatures fluorine of handling through ultra-fine surface layer, but 260 ℃ of its heatproofs, and acid resistance is good, can reclaim silica flour in the flue gas well; Owing to adopt locellus blowing bag-type pulse dust collector 7, in actual use, can under non-stop-machine situation, carry out locellus and change bag, easy to operate, safe and reliable, operating cost is lower.Three, be incorporated in the discharge flue 10 by air-introduced machine 11 through induced duct 9 through the flue gas that deduster was handled, can directly be drained in the atmosphere at last.Four, in the present embodiment, also wind pipe 14 is provided with cold wind air inlet pipe 5, and cold wind air inlet pipe 5 is provided with valve 6.Its effect is: when the also very high or indirect mechanical air cooler 3 of the temperature of the flue gas of handling through indirect mechanical air cooler 3 lost efficacy, the temperature of flue gas does not just reach requirement in the wind pipe 14, at this moment, can open cold wind air inlet pipe 5, the normal temperature air in the external world is drawn in the wind pipe 14 mixes, make the temperature of mixed flue gas drop to required temperature with flue gas.In addition, also can be provided with temperature sensor 13 by wind pipe 14, like this, can be convenient to the duty that control device comes by-pass valve control 6 according to the temperature conditions in the wind pipe 14---open or close.
