Description
Technical field
The utility model relates to a kind of waste gas treatment equipment field, particularly relates to a kind of layering feed flow formula desulfurizing dust-collector.
Background technology
China take coal as the country of main energy sources, is also smoke pollution thing discharge big country in the world.Current China altogether about 420,000, equipment manufacturing industry boiler, year consumption raw coal 1,200,000,000 t, the SO that China in 1997 discharges because of fire coal
2reach 2042 × 104t, account for 87% of the total discharge in the whole nation, flue dust reaches 1124 × 104t, accounts for 60% of national total release.Coal-smoke pollution thing coal fire discharged in a large number defines very large harm in China, and the region that Precipitation pH is less than 5.6 expands rapidly, has accounted for 40% of area, and all in the developed area of China.Estimate the SO of 2000
2discharge capacity is at least at 2500 × 104t.The Acid Rain Pollution that burning coal causes has become an important factor in order of restriction Chinese national economy and social sustainable development.If do not taked favourable control measures, this situation will be accelerated to worsen.
Since the eighties, be environmental protect quality, country delimit regulated area of dust and smoke in China, effectively promote smoke contamination control.The efficient cleaner ratio such as electric precipitation constantly increases, and particularly in power industry, soot emissions obtain effective control.Such as: in power industry, within 1996, compared with 1980, although thermoelectricity installed capacity and coal combustion amount add 3.27 times and 2.8 times respectively, smoke discharge amount is down to 370 × 104t from 399 × 104t.National smoke discharge amount in 1997 is 1873 × 104t, reduces by 150 × 104t than 1996.But, with regard to SO
2; due to technology and economy reasons; not yet be controlled effectively at present; and increasing progressively with the speed of annual 100 × 104t; therefore; the low expense flue gas desulfurization technique tallied with the national condition will Devoting Major Efforts To Developing, and the integrated apparatus research taking into account dust-removal and desulfurizing will become the focus that China's exhaust emission controls.
Traditional wet type desulfurizing dust collector utilizes wet type to collide or flue dust to be thrown on wall and to be washed by the moisture film of deduster inwall by centrifugal force, reaches the object of desulfurization and dedusting.This device once played a positive role to the desulfurization and dedusting of coal-burning boiler, kiln gas.But the weakness that along with going deep into of environmental protection, its efficiency of dust collection is low, desulfurized effect is poor appears gradually, the coal-fired flue-gas discharge standard of current increasingly stringent can not be met.
Summary of the invention
In order to solve the problem that existing dust-removing desulfurating apparatus efficiency of dust collection is low, desulfurized effect is poor; The utility model provides a kind of layering feed flow formula desulfurizing dust-collector, this layering feed flow formula desulfurizing dust-collector adopts multi-layer desulfurization, dedusting structure, can not only remove the pernicious gases such as dust in flue gas and sulfur dioxide effectively up hill and dale, and efficiency of dust collection is high, economical operation, management and maintenance is convenient.
The utility model solves the technical scheme that its technical problem adopts: a kind of layering feed flow formula desulfurizing dust-collector, comprises tower body, exhaust outlet, deashing inspection door, ash discharge lever, solution oxide layer, aerator, air inlet pipe, circulating pump, water pipe, atomizer, distributive pipe, filling block, moisture trap, nozzle; Described tower body top is provided with exhaust outlet, and bottom is provided with deashing inspection door; Deashing inspection door is provided with ash discharge lever; Tower body bottom is provided with solution oxide layer; Air inlet pipe is installed on tower body side, extend in solution oxide layer; Atomizer is communicated with tower body lower end by water pipe, and water pipe is provided with circulating pump; Atomizer overhead is provided with filling block; Nozzle is arranged on distributive pipe, is placed in above filling block; Tower body top is provided with moisture trap.
Described tower body inwall is with corrosion-proof lining, and not easy to wear, corrosion resistance is strong.
Described air inlet pipe is provided with aerator; Exhaust gas diffusion is evenly fully reacted with solution, thus removal foul gas.
Described nozzle head, thus makes the rear speed of solution ejection slow down upward, and waste gas streams is out-of-date can comprehensively be contacted with solution again, again realizes the function of dedusting, desulfurization.
Described atomizer evenly gathers in tower body hollow, and the atomizer between adjacent two layers is interlaced arrangement; Thus the water smoke making adjacent atomizer spray overlaps imbrication mutually, does not interspace, the drop of ejection is made to cover the whole section of tower cover completely.
The utility model, a kind of layering feed flow formula desulfurizing dust-collector, adopts impact type principle, high-temp waste gas containing flue dust, sulphur enters tower body, under the effect of aerator, impact solution, thus make exhaust gas diffusion evenly fully and solution react, thus removal foul gas, reach the effect of catching dirt desulfurization.Cleaning solution is atomized into fine drop by atomizer and sprays equably, and dusty gas is entered by tower cover bottom, bottom-up flowing, both counter current contacting, utilize grit to reunite between phase inter coagulation or grit with the contact-impact of water droplet, its weight is increased greatly, depends on Action of Gravity Field to settle down.The dust be captured makes gravitational settling, and the height bottom being formed contains solid concentrated phase liquid and regularly discharge is for further processing.Purge gas after spray washing, through filling block, again comes in contact with solution and realizes third time dust-removal and desulfurizing effect; After the fine drop of body entrained with of degassing, then be discharged in air by exhaust outlet after being separated by moisture trap.
A kind of layering feed flow of the utility model formula desulfurizing dust-collector, its beneficial effect is:
1) this layering feed flow formula desulfurizing dust-collector makes full use of the useful space in dust catcher chamber, reduces investment and maintenance cost, reaches the object of efficient energy-saving;
2) this layering feed flow formula desulfurizing dust-collector water consumption is very little, substantially all evaporates, does not produce the secondary pollutions such as extra waste water.Desulfurization product can make concrete retarder and admixture activator, can carry out integrated treatment together with the slag of steel mill; Both avoid secondary pollution, meanwhile, also achieve the high added value of desulfurization product;
3) this layering feed flow formula desulfurizing dust-collector has that floor space is little, easy to operate, cost is low, operating cost is low, the advantage of long service life.
