Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is expanded on further.Should be understood that these embodiments are merely to illustrate the present invention rather than limit the scope of the present invention.In addition, it is to be understood that after having read the content that the present invention lectures, the present invention can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application appended claims limited range equally.
As it can be seen, a kind of fume processing technological flow, its technological process is: fume import is to spray-absorption, then is dehydrated dedusting, removes stickum, and micronic dust droplet filters, cooling condensation, except mist deaeration, is finally discharged by floss hole.
Described fume import is provided with emergent floss hole to spray-absorption flow process, prevents the interrupt processing because of equipment fault in follow-up flow process, untreated fume can carry out emergent discharge, it is to avoid cause the impact produced.
Described fume is after spray-absorption, absorb the sewage that in fume, pollution factor is formed need to be for further processing, its water processes sub-technological process: the most heavy process, grid initial filter, deposition filter, air floatation machine processes, pond in entrance, divide the most again two-way: clear water reserviors are directly arrived on a road, enter the circulation of next water；Another road: carry out desolventing technology, quartz sand filtration adsorbs, activated carbon Filtration Adsorption, then to clear water reserviors.
The water of described clear water reserviors returns spray-absorption and forms circulation.
Cause pollute produce because have: solid particulate matter, flue gas, steam and high temperature；Generating the biggest material of viscosity after the cooling of some flue gas, the essence process that the present invention processes is first by during in the fume of industrial discharge, pollution factor transfers to recirculated water, makes gas qualified discharge, then processes recirculated water.
Concrete, described spray-absorption is to be sprayed flue gas by corresponding shower respectively by multiple stage high-pressure hydraulic pump, drenches weighting solids particulate matter, solution absorption flue gas, cooled flue gas；Dehydration dedusting is formed by organizing cyclonic separation unit more, utilizes centrifugal force weight in wet base particulate matter and drop to be separated from flue gas；Remove stickum to be made up of a series of flaps, capture those stickums formed because of cooling, and allow it automatically wander, because one Processing Equipment under the influence of the meeting of these stickums；Micronic dust droplet filters and is made up of finer drainage screen and self-stripping unit, after former roads PROCESS FOR TREATMENT, still has some micronic dusts and droplet；Cooling condensation is made up of numerous cooling tubes, and pending flue gas, at cooling Bottomhole pressure, carries out heat exchange by tube wall with external environment and cools down；Because flue-gas temperature at this moment is the highest, absolute humidity is big, especially autumn and winter season, if emit necessarily be cooled to mist and dissolve those not processed fall trace harmful gases；Except mist deaeration is made up of the filter cloth bag of super large surface area and densification, filter superfine little mist.Processing through one flow process, the pollutant in flue gas are eliminated substantially, and gas temperature is also close to ambient temperature, can not only qualified discharge, nor haze can be formed.
Fume is after spray-absorption, and during in fume, pollution factor transfers to recirculated water, the most heavy process is to utilize preliminary sedimentation tank that the most heavier material is carried out precipitation process；Grid initial filter is to utilize grid that material lighter relatively greatly is carried out primary filter process；Deposition filter is to precipitate less deposit and less suspended material and filtration treatment；It is that tiny float is carried out dissolved air flotation process that air floatation machine processes；Pond in water body entrance after process.
Owing to discharge is bigger, the moisture two-way in middle pond, a road is directly arrived clear water reserviors, is entered the circulation of next water；Another road carries out the bleaching that decolours to water body；Quartz sand filtration is to adsorb small float and filtration treatment；Activated carbon adsorption is that the organic gas molecule being dissolved in water is carried out adsorption treatment, and the clear water after process enters in clear water reserviors, and such purpose is to remove the pigment in water and organic harmful gas molecule, say, that process in water circulates.
A kind of fume processing technological flow of the present invention, each pollution factor is classified classification multistage treatment process design, have dedusting, smoke abatement, except mist and deaeration comprehensive function, it is possible to the pollution to industrial discharge fume reaches sufficient treatment effect.
