Abstract
The invention discloses a high temperature flue gas purification device used for the metallurgy and building materials industries and provides a high temperature flue gas purification device which has the advantages of better purification effect, low concentration of the gas emission and reduction of the energy consumption; the device includes a high temperature flue gas generation device, a draft fan and an exhaust funnel which are connected by pipelines in series; the high temperature dust collector is connected with the high temperature flue gas generation device and the draft fan by the pipelines; as the cooling device is omitted, the device has the advantages of small occupy area and small maintenance, does not need dust blocking and cleaning work for the cooling device, reduces the operation points for unloading dust, reduces the energy consumption of the system, does not has cooling consumption, has low total pressure of the main system fan and reduces the motor power; As the high temperature flue gas is purified in the high temperature region directly, and then interfused into the atmosphere, the high temperature flue gas purification device can reduce the temperature rapidly and cuts down the temperature section in which the dioxin is generated.
Description
Technical field
The present invention relates to a kind of metallurgy, building material industry high-temperature smoke purifier.
Background technology
The purifier of high-temperature flue gas is that high-temperature flue gas generation equipment, cooling infrastructure, deduster, air-introduced machine, aiutage connect successively by pipeline in the prior art, owing to be provided with cooling infrastructure in the device, so the configuration of the pipeline of device is long, occupation area of equipment is big, equipment investment expense height; Owing to before cooling infrastructure is arranged on deduster, enter the dust contained flue gas of cooling infrastructure, cause cooling infrastructure often to stop up, need often to safeguard; Cooling infrastructure needs additional energy; Whole device resistance height, between 4500-7100Pa, the main air blower energy consumption is big.
Summary of the invention
Technical problem to be solved by this invention provides the high-temperature smoke purifier that a kind of clean-up effect is better, the discharging flue gas concentration is low, cut down the consumption of energy.
Technical scheme of the present invention is: a kind of high-temperature smoke purifier, comprise the high-temperature flue gas generation equipment, air-introduced machine, the aiutage that connect successively by pipeline, and also be connected with hot precipitator by pipeline between described high-temperature flue gas generation equipment and the air-introduced machine.
Be provided with high temperature resistant filter core in the described hot precipitator, described high-temperature flue gas generation equipment is the hot stove in semi-hermetic ore deposit, can also be the cupola furnace, electric arc furnaces.
Beneficial effect: owing to omitted cooling infrastructure, thus plant area province, and maintenance is little, and the stifled ash of no cooling infrastructure, deashing work are unloaded ash manipulation point and are reduced; Reduced system's operation energy consumption, nothing is cooled off energy consumption, system's main air blower total head is low, and power of motor reduces; Because high-temperature flue gas directly purifies at high-temperature area, the later stage is directly sneaked into atmosphere, and fast cooling has been cut down the temperature section that dioxin produces significantly; The filtration velocity height is more than 2 times of conventional high temperature fabric filtrate; Concentration of emission is low, can guarantee to discharge dust concentration at 8mg/N.m

Description of drawings
Fig. 1 is a high-temperature smoke purifier structural representation of the present invention
The specific embodiment:
The present invention is further illustrated below in conjunction with accompanying drawing
Among the figure, a kind of high-temperature smoke purifier comprises the semi-hermetic ore deposit thermic arc stove 1, air-introduced machine 5, the aiutage 6 that are connected successively by pipeline, also is connected with hot precipitator 3 by pipeline 2,4 between described semi-hermetic ore deposit thermic arc stove 1 and the air-introduced machine 5.
Be provided with high temperature resistant filter core in the described hot precipitator, its material is the sintering class formation of similar pottery, generally can bear the long-term work temperature about 600 ℃, high energy bears 1600 ℃ high temperature, and can bear that high temperature is oarse-grained to be washed away, therefore can the direct purification high-temperature flue gas, and do not need to do any preliminary treatment, the dust concentration after the purification is substantially at 2～8mg/N.m
3, and filtration velocity is higher, generally between 1 ~ 2m/min.
Because limiting temperature＜350 that can bear of fabrics in general class filter element ℃, generally require long-term work temperature＜280 ℃; And especially can not bear the higher bulky grain thing of internal temperature in the high-temperature flue gas; Therefore when handling high-temperature flue gas purification, must earlier flue gas be carried out preliminary treatment, generally include the cooling of bulky grain sedimentation and flue gas, equipment is many, long flow path, and energy consumption is big; System also needs to consider to sneak into a large amount of cold airs during design, has strengthened the processing load of system; Because the fabric self character, the dust concentration after the purification is substantially at 20～50mg/N.m
3(existing GB is 50mg/N.m
3).And filtration velocity is low, generally between 0.9 ~ 1.2m/min.
And workflow of the present invention is: when flow 12 * 10
4N.m
3/ h, 500 ℃ of temperature, dust content is 13g/N.m
3The high-temperature flue gas source through semi-hermetic ore deposit thermic arc stove 1, flue 2 is transported to hot precipitator 3, dust content 5mg/N.m after hot precipitator 3 purifies
3, guided by air-introduced machine 5 through pipeline 4, enter atmosphere by aiutage 6, this moment, flue-gas temperature was 300 ℃.The purifier system needs main air blower 400KW approximately in the prior art, and cooling blower 180KW adds up to 580KW, and air-introduced machine power only needs 250KW now.
To produce 75Si, transformer capacity 25500KVA ore deposit thermic arc stove dust collecting process is an example, and device of the present invention is forced cooling after-purification device relatively with conventional, is described as follows:
Annotate: work per year and calculated in 330th.
Low by the visible smoke dust discharge concentration of the present invention of table, the device operation energy consumption is low, and clean-up effect is better.
