Abstract
The invention discloses a combined method for purifying a dusty flue gas. The method comprises the following steps: enabling a to-be-purified flue gas to penetrate through a spraying device, arranging a nozzle in the spraying device to spray the flue gas, feeding the flue gas to a high-pressure electromagnetic field area after spraying, so as to electrify dust particles in the flue gas in a uniform collision manner under the action of the electromagnetic field; feeding the flue gas which penetrates through the high-voltage electromagnetic field to multiple groups of dust baffle plates; and arranging a washing liquid flow screen in each dust baffle plate, enabling the spray liquid which is the same as that of the spraying device to flow on each washing liquid flow screen, and carrying out gas-liquid contact on dust particles in the flue gas on the dust baffle plates and the washing liquid flow screens to generate bubbles to further remove dust. According to the method for purifying the flue gas, the peculiar smell in the gas can be removed; bacteria can be decomposed; high-pressure electrostatic pollution of equipment can be removed; a great number of negative ions beneficial to a human body can be generated; meanwhile, the dust accumulation phenomenon of a dust-collecting plate can be prevented; secondary dust blowing is avoided; and the equipment has a self-cleaning function, and has the advantages of no need of maintenance and no need of unpicking or washing.
Description
Technical field
The present invention relates to a kind of method that combined type purifies metallurgical ash-laden gas.
Background technology
Production and processing type enterprise all also exists vent gas treatment problem, particularly particularly serious at the dust pollution of cement production enterprise, a large amount of short grained dust is there is and flies upward in the tunnel of manufacture of cement and the belt conveyor of bottom of the reservior everywhere when discharging, because there are unequal emptying point and reloading point in all kinds of tunnel and bottom of the reservior, there are at most twenties, these emptying points are arranged because space constraint is horizontal pipe, the horizontal pipe of long distance very easily causes line clogging, cloth wind is uneven again for each airborne dust point, so the dust removing effects of general deduster is undesirable, be difficult to reach discharge standard.In addition, because dust stains seriously, when belt conveyor runs, operator cannot enter tunnel and bottom of the reservior and carry out making an inspection tour and overhauling, and nearly 200 meters of Belt Conveying line length, easily produce fault, have impact on the economic benefit development of enterprise; And bring negative effect to worker is healthy.
So enterprise is in order to reach the index of environmental protection, discharge after adopting various dust arrester to carry out absorption process to the tail gas produced in production, as methods such as gas wash tower, dust settling pocket, Water spray, the tail gas after process meets the requirement of discharge substantially again.Wherein, sack cleaner is owing to dropping into little, arrangement convenience, good dedusting effect and being used by vast enterprise.
At present, gas cleaning is generally based on wet type and dry type two kinds, and wherein, the method for wet type is generally the modes such as washing spray irrigation and cleans, and the method for dry type adopts physical filtering to carry out in conjunction with Electrostatic Absorption mode.But traditional wet-cleaned mode, its cleaning efficiency is directly by affecting time of contact of gas-liquid and the way of contact, in general high-pressure atomization mode gas-liquid contact, its cleaning efficiency is higher, but this mode is high to equipment requirement condition, and liquid damages large, easy blocking, the shortcomings such as maintenance cost is large, in addition under gas flow rate faster situation, cause secondary pollution.And current Electrostatic Absorption technology, be divided into the large class of wet method and dry method two, wet method mainly contains tubular type, honeycomb fashion, bushing type, and dry method mainly contains board-like, pipe curtain formula and dual zone type, version affects by factors such as Purge gas flow velocity, dustiness concentration, electrostatic precipitation board stacks, produce pole plate cavitation, gas occurs and omits phenomenon in printing, purification efficiency is reduced, cause secondary pollution, and equipment volume is large, floor space is large, and equipment investment cost is high.
Summary of the invention
The object of the invention is to propose a kind of method that combined type purifies metallurgical ash-laden gas.
For reaching this object, the present invention by the following technical solutions:
A kind of combined type purifies the method for metallurgical ash-laden gas, comprise the following steps: by need purification flue gas pass through sprayer unit, nozzle is provided with for spraying flue gas in sprayer unit, spray liquid is the OP-10 surfactant solution of 2-3wt%, flue gas enters high-voltage electromagnetic field district after spraying, voltage is 500-1000V, and magnetic field intensity is 5000-10000 Gauss, and evenly collision is charged under the effect of electromagnetic field to make the dust particle in flue gas; Flue gas subsequently through high-voltage electromagnetic field enters many group dirt baffle plates, shield in the upper flow of liquor that is provided with of dirt baffle plate, flue gas to be clean shields through flow of liquor under fan action, flow of liquor screen flows the spray liquid identical with described sprayer unit, and the dust particle in flue gas at dirt baffle plate and flow of liquor screen, gas-liquid contact occurs and produces bubble with further dedusting.
The method of this purifying smoke can remove gas peculiar smell, decomposing bacteria, and the high-pressure electrostatic that abatement apparatus self produces pollutes, a large amount of anion useful to human body can be produced, prevent collecting plate laying dust packing phenomenon simultaneously, avoid reentrainment of dust, make equipment itself have self-cleaning function and non-maintainingly unpick and wash advantage.
