Abstract
The utility model relates to a dust removing system for a silicon manganese alloy airtight electric stove, which is used for carrying out dusting and purifying treatments on dust, coal gas and the like discharged by the silicon manganese alloy airtight electric stove. The dust removing system comprises a gravitational settling cooler for carrying out primary dust removing on the stack gases, air coolers for carrying out secondary dust removing on the stack gases, bag-type dust removers for carrying out tertiary dust removing on the stack gases and pipelines for carrying out stack gas transportation, wherein cyclone devices for producing cooling cyclone are arranged in the air coolers, and the gravitational settling cooler, the air coolers and the bag-type dust removers are communicated through the pipelines in sequence. Through the adoption of the structural design, three dust removing devices, namely the gravitational settling cooler, the air coolers and the bag-type dust removers are adopted to carry out dust removing on the stack gases in sequence, and meanwhile can also cool the stack gases, so that through the three-level drying and cooling of the stack gases, a purifying effect of the stack gases can be greatly improved, and purified coal gas discharged by the silicon manganese alloy airtight electric stove at last is enabled to meet use requirements.
Description
Technical field
The utility model relates to a kind of silicomangan closed electric furnace dust pelletizing system.
Background technology
Totally-enclosed silicomanganese producer gas purifies, wet processing---" two civilian towers " wet dedusting coal-gas recovering is utilized system to common employing of past, wet processing not only exists pipe-line equipment to stop up, purify not up to standard, the problem of maintenance management difficulty, but also exist water resource waste, cyanide wastewater also to need the problems such as processing.
China is in also clear of formal " cleaner production standard steel industry ferroalloy " GBHJ-2009 implemented on August 1st, 2009, the totally-enclosed electric furnace that is greater than 25000KVA should adopt the dry cleaning device, and answer the gas recovery utilization, secondary energy sources are fully utilized, but have that investment is high, coal gas utilizes safety problem and the coal gas purposes few etc.
The utility model content
The utility model technical issues that need to address are to provide a kind of silicomangan closed electric furnace dust pelletizing system.
For addressing the above problem, technical scheme that the utility model is taked yes: a kind of silicomangan closed electric furnace dust pelletizing system, carry out the dedusting operation for the flue gas that the silicomangan closed electric furnace is discharged, include:
Flue gas is carried out to the gravitational settling cooler of primary dust removing;
Flue gas is carried out to the aerial cooler of two-stage dust removal, be provided with the cyclone for generation of cooling whirlwind in described aerial cooler;
Flue gas is carried out to the sack cleaner of 3-stage dust-removal;
For the pipeline that carries out the flue gas conveying, described gravitational settling cooler, described aerial cooler and described sack cleaner are communicated with successively by described pipeline.
Preferably, described aerial cooler includes two, and two described aerial coolers are by described pipeline series connection.
Preferably, described sack cleaner includes three, and three described sack cleaners are by described pipeline parallel connection.
Design by said structure, adopt gravitational settling cooler, aerial cooler and three dust arresters of sack cleaner successively flue gas to be carried out to dedusting, can also carry out cooling to flue gas simultaneously.So, cooling by flue gas being carried out to three-stage drying, can improve dramatically the clean-up effect of flue gas, thereby make the last clean coal gas of discharging of silicomangan closed electric furnace meet instructions for use.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein: 1, gravitational settling cooler, 2, aerial cooler, 3, sack cleaner.
The specific embodiment
Below in conjunction with accompanying drawing, utility model is described in further detail: as shown in Figure 1, the utility model provides a kind of silicomangan closed electric furnace dust pelletizing system, carry out the dedusting operation for the flue gas that the silicomangan closed electric furnace is discharged, in the utility model, silicomangan closed electric furnace dust pelletizing system includes: the gravitational settling cooler 1 that flue gas is carried out to primary dust removing; Flue gas is carried out to the aerial cooler 2 of two-stage dust removal, be provided with the cyclone for generation of cooling whirlwind in aerial cooler 2; Flue gas is carried out to the sack cleaner 3 of 3-stage dust-removal; For the pipeline that carries out the flue gas conveying, gravitational settling cooler 1, aerial cooler 2 and sack cleaner 3 are communicated with successively by pipeline.
Along with the fast development of China environmental protection industry, adopting advanced dry method---sack cleaner purifies coal gas, and concentration is controlled at 50mg/Nm
3below, the whole recyclings of coal gas have become enterprise's inevitable choice.
In the said structure design, adopt gravitational settling cooler 1, aerial cooler 2 and 3 three dust arresters of sack cleaner successively flue gas to be carried out to dedusting, can also carry out cooling to flue gas simultaneously.So, cooling by flue gas being carried out to three-stage drying, can improve dramatically the clean-up effect of flue gas, thereby thereby make the silicomangan closed electric furnace make the last clean coal gas of discharging of silicomangan closed electric furnace meet instructions for use.
In a specific embodiment of the present utility model, pipeline is communicated with the exhaust opening of silicomangan closed electric furnace, and at first flue gas enters into gravitational settling cooler 1 by pipeline, realizes the primary dust removing of dust by Action of Gravity Field.Then, enter into the aerial cooler 2 of two series connection by pipeline by the flue gas in gravitational settling cooler 1, aerial cooler 2 can produce eddy flow wind, not only can accelerate the cooling of flue gas, can also improve the clean-up effect of flue gas simultaneously.Flue gas is successively through after two aerial coolers 2, by pipeline and under the effect of blower fan, enter into respectively (three sack cleaner 3 parallel connections) on three sack cleaners 3, the top of three sack cleaners 3 is provided with pipeline, flue gas can enter on three sack cleaners 3 simultaneously, then by pipeline, is discharging.
Particularly, aerial cooler 2 includes two, and two aerial coolers are connected by pipeline.
Particularly, sack cleaner 3 includes three, and three sack cleaners are by the pipeline parallel connection.
The high-temperature flue gas that electric furnace produces forces whirlwind aerial cooler 2 to be cooled between 220 ℃-250 ℃ through flue, one-level gravitational settling cooler 1, two-stage, simultaneously by oarse-grained trapping dust in gas.Temperature is controlled between 220 ℃-250 ℃, mainly contains following target: one, prevent that tar from separating out lower than 200 ℃ the time and blocking pipe; Two, prevent excess Temperature, damage deduster and Fan Equipment etc.High-temperature flue gas continues to enter sack cleaner 3 after thick gas blower fan and filters, and the gas after filtration is delivered to booster station through the pure qi (oxygen) blower fan, then through booster fan, gas boosting is delivered to hot-blast stove for user's sintering to required pressure.Dust under gravitational settling cooler 1, pressure whirlwind aerial cooler 2 and 3 three device filters of sack cleaner are delivered to the total storehouse of dust by sealed chain mat machine.
The utility model has the advantage of: (1) has been improved the recycling of valuable resource in the exhaust gas dust and has been worth; (2) saving water resource; (3) improve the utilization ratio of Gas Resource.
By said structure, design, the utility model come into operation rear electric furnace operating rate by before 90% be increased to 98%.Coal gas containing CO, H2, CH4 etc. effectively propellant composition account for gas volume ratio by before 55% be increased to 80%, the recycling that has improved greatly coal gas is worth.
