Description
Technical field
The utility model relates to the corollary equipment of industrial furnace, and more particularly, the utility model relates in particular to a kind of for industrial furnace is clean and the corollary equipment of recovery waste heat.
Background technology
Current industrial circle, stove is widely adopted with combustion of fossil fuel generation heat energy and reaches certain production object, after industrial furnace fuel combustion, gives off flue gas, and flue gas is the heterogeneous aerosol that solid, liquids and gases material form, and Main Ingredients and Appearance is CO
2, H
2o, CO, NO and flue dust, wherein flue dust belongs to particle contamination, and particle contamination is one of important pollutant of atmosphere, and atmosphere pollution has day by day seriously directly jeopardized the comfortable, healthy of human body, and even the environment that the mankind depend on for existence, the oxious component in flue gas need to be burnt and be reduced discharge with dedusting by improvement.
Traditional industrial furnace flue gas ash removal, mainly adopts dust removal with machine, electrostatic precipitation, filtering type bag-type dust, washing type wet dedusting etc.Because high-temperature flue gas has very vigorous erosion destructive power to the equipment of traditional deduster, filtering material, impact that also can be on the thermal expansion of deduster structure generation, and the Applicable temperature of traditional deduster is low, therefore, high-temperature dust removal effect is bad, generally can only between 50-200 ℃, effectively work.
For temperature, reach the dedusting of 200 ℃-1000 ℃ and above high-temperature flue gas, at present the main way that adopts first cooling to use again traditional deduster dedusting; Cool-down method mainly contain directly cooling as: adopt that wild wind is cooling, water cooling etc.After wild wind cools, exhaust gas volumn increases, and waste heat recovery efficiency is low, and thermal loss is large; Water cooling cooling increases the complexity of dust pelletizing system, and cooling-down effect is also bad.
The states such as U.S., moral, Japan are explored electric cleaner for high-temperature dust removal, are mainly at present the experimental stage, and existing reaching under 650～790 ℃, 570kpa moved the experimental record of 100 hours, and efficiency of dust collection can reach 95%～99.5%; But have that corona discharge is unstable, electrode life is short, to problems such as smoke components sensitivity, high-temperature insulations, in the short time, be difficult to break through.
The high-temperature dust removal technology of having studied or having studied also has pottery to knit shape filter, ceramic fiber filter, metal felt filter, sintered metal mesh pipe filter, too cotton filter etc., the filter efficiency of these dedusters can reach more than 99%, but all there is problem separately, as strength problem, permanent plugging Problem of Failure, Cost Problems etc.
The domestic report that has various granular-bed filters, is mainly moving granular bed filter and ebullated bed granular-bed filter, and these granular-bed filters all adopt flue gas to pass through from the top down grain bed, and particle is fluidization or boiling shape when reverse gas cleaning.New and effective double layer particle height of bed temperature filtering technique and the equipment of up-to-date report Shi Yang state China professor research and development, its basic principle is: filter course is comprised of lightness sensation in the upper and heaviness in the lower, upper coarse and lower fine double-layer filter material, as above metafiltration material is expanded perlite granule, and lower floor's filtrate is extra large sand.During filtration, ash-laden gas through filtering layer, first passes through coarse grained upper filter material layer from top to bottom, the most dust in entrap gas, then pass through the lower filter material layer of fine grain, intercept and capture the fine dust that leaked filtering layer.During reverse gas cleaning, blowback air is from bottom to top by filtering layer, and two-layer filtrate is all fluidization, and intergranular dust is entrained out by air-flow, reaches quick deashing.Due to 1/20 of upper strata filtering material particle density Jin Wei lower floor filtrate, upper strata filtering material particle is suspended on lower floor's filter material layer all the time, and two-layer filtrate is not mixed mutually mutually, remains that double-decker is constant.But, this granular-bed filter does not still change conventional particles layer filter flue gas and passes through from the top down grain bed, still exist dust on grain bed top, to be difficult to the problem of cleaning, fluidised reverse gas cleaning easily produces irregular operation, affects efficiency of dust collection.And existing deduster is not for the waste heat recovery of high-temperature flue gas and effectively utilization.
