Abstract
The present invention relates to a kind of fume desulfurizing and dedusting technology, boiler original flue gas is set to enter reactor, some nozzle composition spraying layers are arranged in Venturi tube aditus laryngis shrinking zone, the active oxygen absorbing liquid that oxygen activation device is produced sprays into the aditus laryngis shrinking zone of Venturi tube by nozzle atomization, it is dispersed into tiny drop and covers the whole section of aditus laryngis, drop is fully contacted with flue gas in aditus laryngis, and high intensity mass transfer, the S0 in flue gas occur2Aoxidized by active oxygen, be dissolved in drop formation sulfuric acid.In the reactor and area, the lime sent into batcher carries out neutralization reaction, generates calcium sulfate；Flue gas after dedusting enters chimney by air-introduced machine.The present invention is brand-new technique, and efficiency high, small investment, operating cost is low.
Description
, technical field
Specifically refer to a kind of fume desulfurizing and dedusting technology the present invention relates to desulfurization and dedusting skill technical field.
, background technology
At present using the external technology introduced more than country's flue gas desulfurization, such as catalytic reducing smoke technique, the gypsum wet sulfur removal technology of lime/lime stone one, these techniques have purification efficiency higher, it is big with floor space but absorption tower volume is very huge, capital intensive, operating cost is big, the construction and installation cycle is long, the disadvantage such as operational management difficulty, especially also wants dependence on import with catalyst.Therefore, researching and developing the desulphurizing capacity technology and equipment for the economic and reliable of China's coal-fired plant boiler, Industrial Boiler and other Industrial Stoves, make its industrialization and form production scale, be China promote smoke gas treatment work in the urgent need to.
, the content of the invention
The purpose of the present invention, is the weak point for overcoming existing desulfurization technology, there is provided a kind of desulfurization dust-removing efficiency is high, small investment, the low brand-new efficient flue gas desulfurization and dust removal integrated technique of operating cost.
The purpose of the present invention is achieved through the following technical solutions：
A kind of fume desulfurizing and dedusting technology, it is characterised in that：It is that boiler original flue gas will be made to enter reactor, some nozzle composition spraying layers are arranged in Venturi tube aditus laryngis shrinking zone, the active oxygen absorbing liquid that oxygen activation device is produced sprays into the aditus laryngis shrinking zone of Venturi tube by nozzle atomization, it is dispersed into tiny drop and covers the whole section of aditus laryngis, drop is fully contacted with flue gas in aditus laryngis, generation high intensity mass transfer, the S0 in flue gas2Aoxidized by active oxygen, be dissolved in drop formation sulfuric acid.In the reactor and area, the lime sent into batcher carries out neutralization reaction, generates calcium sulfate；Flue gas after dedusting enters chimney by air-introduced machine.
Described molecular-sieve oxygen generator, is obtained oxygen of the concentration more than 93%.
Described acts the deduster for gathering dust, and can select sack cleaner, or electric-bag complex dust collector.
The excellent feature of technique of the invention is：
1. square pipeline reactor can be directly mounted on flue, and constitute an entirety with deduster gas approach；
2. small volume, it is lightweight, transport simple installation, short construction period；
3. floor space is small, is particularly well-suited to old stove desulphurization denitration transformation：
4. reduced investment, operating cost be low but desulfuration efficiency it is high >=90%;
5. reactor outlet cigarette temperature is more than dew-point temperature more than 15 DEG C, without heat exchanger；
6. there are various functions, can simultaneous SO_2 and NO removal dedusting；
7. sweetening process is produced without waste liquid, and accessory substance is disposable.
, specific embodiment
Embodiment
Venturi tube enters at the former reacted device bottom elbow inlet of flue gas, some nozzle composition spraying layers are arranged in Venturi tube aditus laryngis shrinking zone, active oxygen absorbing liquid sprays into Venturi tube aditus laryngis shrinking zone by nozzle atomization, it is dispersed into tiny drop and covers the whole section of aditus laryngis, these drops are fully contacted with flue gas in aditus laryngis, and high intensity mass transfer occurs.SO in flue gas2Aoxidized by active oxygen, after there is above-mentioned chemical reaction, be dissolved in generation nitric acid and sulfuric acid in drop；Reactant enters reactor neutral zone with the reacted device zoneofoxidation of flue gas, and now flue gas is cooled down, and humidity increases, and above-mentioned neutralization reaction occurs with the lime 15 being evenly mixed in flue gas with area in the reactor, mainly generates thing for calcium nitrate and calcium sulfate.Reacted flue gas carries substantial amounts of solid particle and enters deduster, is separated from flue gas by deduster, is conveyed to byproduct storehouse again by pneumatic transport equipment.Flue gas 14 after cleaning, without reheating, chimney is entered by air-introduced machine in more than 15 DEG C of dew-point temperature.
