It has raised dust and sulfur eliminating rate and can eliminate oil burning black smoke in efficiency of not lower than 99 %. In addition, the apparatus of the present invention has relatively low cost.
Description
Technical field
The invention belongs to environmental protection air contaminant treatment equipment, especially wet method-electrostatic dust-removing, desulfurizing equipment and remove fuel oil flue dust equipment.
Background technology
Along with China's coal changes the enforcement of oily policy, the fuel oil flue dust (black smoke) of industry and life usefulness is more and more serious to the pollution of air.Yet, because the carbon black and the small amount of impurities that form in the soot that the main component of fuel oil flue dust (black smoke) is produced by incomplete combustion, the combustion process are formed, have temperature height (general 200-300 ℃), oiliness is arranged, fine particles (generally＜1 μ m), littler by (≤10 than resistance
3Ohmcm), proportion is little, be difficult for affinity (hydrophobicity) with water, the characteristics such as (SO2, HF etc.) that contains corrosive gas, therefore, is a big technical barrier in environmental protection field to the improvement of fuel oil flue dust (black smoke) always.Existing fuel oil flue dust (black smoke) technology of removing mainly contains electrostatic precipitation, wet dedusting desulfurization, bag-type dust, wet method-static two-stage dust removal desulfurization etc.Wherein electrostatic precipitator technology since the low resistivity of dust (than resistance≤10
3Ohmcm), in the efficient scope (10 of electrostatic precipitation
4～5*10
10Ohmcm) outside, it is serious that black smoke returns to the air-flow phenomenon, therefore removes the black smoke weak effect; The wet dedusting desulfurization technology, because the subparticle characteristic and the hydrophobic character of dust, it is very poor therefore to remove the black smoke effect; Conventional dust settling pocket technique though remove black smoke efficient height, because flue-gas temperature height and have oiliness and corrosivity, requires highly especially to the cloth selection of cloth bag, also need cooling measure, so cost is high, and desulfurization simultaneously, generally also less use; The wet method of up-to-date use-static two-stage dust removal desulphurization plant, as number of patent application 03114336.9, though to the clearance of dust and sulphur than higher, but because low resistivity characteristic and the fine particles characteristic and the hydrophobic character of dust, therefore it is also undesirable to remove the black smoke effect, the requirement that does not still reach environment protection treating.
Summary of the invention
The objective of the invention is to design a kind of new equipment, not only to the clearance of general dust and sulphur than higher, and can effectively remove the fuel oil black smoke.
Realize that technical scheme of the present invention is on wet method-static two-stage dust removal desulphurization plant basis at number of patent application 03114336.9, add the screen cloth 4 that the numbers of plies do not wait in the wet dust removal desulphurization device 3 therein, and make screen cloth 4 and flue gas flow direction tangent.In flue gas enters wet dust removal desulphurization device 3, under the effect of water gravity and blower fan gravitation, flue dust (black smoke) and water must pass the fine mesh of screen cloth 4 jointly, flue dust (black smoke) and water have been subjected to the encirclement and the extruding of water when passing the mesh of screen cloth jointly, the multilayer screen cloth makes this encirclement and pushes repeated multiple times and be accompanied by strong collision.Soot, carbon black are forced to fully contact with water so on the one hand, are soaked (affinity) by hydrone or are surrounded (affinity) by hydrone until soaked (affinity) or part by hydrone; Soot, carbon black oneself extruding, collision make particle become big chap on the other hand.When dust and water pass the screen cloth hole jointly and is forced to affinity, also have a factor to play positive catalytic action, i.e. temperature one heat energy of flue gas.Because flue gas enters temperature height (200～300 ℃) before the spray column, enters after the spray column, water fully contacts with flue gas, absorbed the heat of flue gas and make flue gas cool-down to≤100 ℃, so water has certain temperature.The water of uniform temperature can be guaranteed the activity of hydrone, and the affinity of soot, carbon black is played positive catalytic action.Behind soot, carbon black and water affinity, because the ratio resistance and the proportion of water are all big, therefore, water has just become to increase resistance agent, weighting agent and adhesive, thereby overcome the defective such as hydrophobicity, low resistivity, fine particles, light specific gravity of soot and carbon black, made soot and carbon black enter the ratio resistance range (10 of electrostatic precipitator high-effective dust-removing
4～5*10
10Ohmcm).Like this when and the water affinity soot and carbon black enter in the electrostatic dust-removing, desulfurizing device 16 by smoke dust duct 13 and just can be separated from flue gas by statcoulomb power easily, and no longer returned to air-flow, by automatic spray cleaning device 17 black smoke is cleaned in the pond 10 then, reach the purpose of efficient removing black smoke.
The present invention also draws by repetition test: the efficient of removing the fuel oil black smoke is relevant with the order number and the number of plies of screen cloth 4 in the wet dust removal desulphurization device 3, the order number of screen cloth 4 is bigger, the number of plies the more, soot and carbon black are subjected to that water surrounds, the chance of extruding, collision just the more, with the water affinity better, efficiency of dust collection is higher.But fan pressure loss simultaneously is also bigger, and power consumption the more.Have the order number and the number of plies scope of removing fuel oil flue dust (black smoke) effect of the screen cloth 4 in wet dust removal desulphurization device 3 are: sieve number 4～1000 orders, 1～500 layer of the screen cloth number of plies, but the order number and the number of plies scope of the optimum of the screen cloth 4 in wet dust removal desulphurization device 3 are: sieve number 18～30 orders, 18～30 layers of the screen cloth numbers of plies.In wet dust removal desulphurization device 3 screen cloth 4 have remove fuel oil flue dust (black smoke) effect to flow to the corner cut scope with flue dust be 10 °～90 °, but in wet dust removal desulphurization device 3 optimum of screen cloth 4 to flow to the corner cut scope with flue dust be 60 °～90 °.In order to reduce the loss of fan pressure, generally flue gas flow direction is designed to spray the direction unanimity with water from top to bottom simultaneously, the potential energy loss of water can partly be converted into wind energy like this, thereby reduces the loss of blast, reaches further purpose of energy saving.
The present invention has following remarkable result: the invention provides a kind of not only to the clearance of general dust and sulphur than higher, and can effectively remove the fuel oil black smoke, remove black smoke efficient 〉=99%, satisfy fuel oil flue dust (black smoke) equipment that removes of national waste gas pollution control and treatment discharge standard fully, solved a big technical barrier of at present fuel oil flue dust (black smoke) being administered.The present invention also has cheap, economical and practical advantage, and it is high to have overcome conventional cloth bag dedusting technology cost, and the defective of desulfurization simultaneously.
