Description
Technical field
It the utility model is related to a kind of demisting dust arrester, and in particular to a kind of cyclone demisting dust arrester.
Background technology
SO2It is the important pollution sources that cause China's atmosphere pollution with dust, the day controlled with country atmosphere pollution
Benefit is paid attention to, SO2It is more and more stricter with the emission request of dust.At present, Wet Flue Gas Desulfurization Technique is used mostly in field of Environment Protection, wet
In method technique flue gas desulfurization course, " mist " that particle diameter is 10~60 microns is also easy to produce, not only contains moisture, also dissolved with sulfuric acid, sulphur
Hydrochlorate, SO2And fine particle etc., dust content is exceeded after causing desulfurization, and atmospheric environment is polluted, while follow-up equipment is made
Into more serious corrosion.Therefore, in wet desulfurizing process, purification gas has to carry out at demisting dedusting in absorption tower outlet
Reason.
Demister is the processing equipment that the fields such as chemical industry or environmental protection are used for gas-liquid separation.When the gas containing mist is with certain
Speed when passing through demister, can and demister internal structure bump against, and depend in its surface.Demister internal structure surface
On mist,, will be inside demister after weight reaches certain level by spreading and the effect of gravity can progressively be assembled
Separated in structure.So as to realize gas-liquid separation.Demister is generally located at the top of absorption tower.When demister is in running
It is middle because of fouling and caused by resistance when increasing to predetermined value, it is necessary to start backwashing procedures is rinsed to demister, typically,
Demister inlet end and exhaust end are both needed to set flooding nozzle.Serious entrainment of the gas phase to liquid phase may now be caused, cause gas
Carry a large amount of droplets in stream secretly.
Many types can be divided into according to the purposes of demister, structure, as mesh mist eliminator, collapser demister, electricity remove
Day with fog, venetian blind type demister and gravitational settling type demister etc..Conventional has mesh mist eliminator, collapser demister etc..Silk
Although net demister can separate in general mist, it is required that mist cleaning, air-flow velocity are smaller, and resistance drop is big, service life
Short, equipment investment is big.Demister typically all uses horizontally disposed at present, and demister gas flow direction is vertical with silk screen, gas velocity
When relatively low, the mist inertia of entrainment is small, is drifted in gas, it is impossible to it is removed with silk screen making contact, and due to being divided
Chaotropic is dripped to be flowed to gas phase in adverse current, and gas is also easy to produce reentrainment to drop, so that gas-liquid separation efficiency reduces, and silk
The problems such as easily blocking, pressure drop is big also be present in net demister.Be provided with inside blade type, herringbone demister direction it is different,
The different deflection plate of shape, to form small runner, increase defogging effect, structure is more complicated, and separating effect is bad.
United States Patent (USP) US7618472B2 provides a kind of vane-type demister, and the demister is by corrugated sheet, flat board and hundred
Leaf luffer boards etc. are formed, and form many cavitys or runner.After gas-liquid mixture enters demister, fluid course shifts, and makes
Fluid flow direction is obtained for several times to be changed, and velocity variations is very fast, and liquid phase is easy to separate from gas phase.The technology liquid
Mutually by gas phase separation process, it is possible to achieve gas liquid cross-flow, therefore reentrainment effect of the gas phase to drop substantially reduces, still
The technical pattern is extremely complex, and difficulty of processing is also bigger, and corresponding processing and fabricating expense is higher.
The demister element that patent CN200410014713.X is introduced is made up of deflection plate and flue gas flow field adjustment block, deflection plate
It is fixed in flue gas flow field adjustment block, the density and shape of deflection plate change according to the flow area change of flow field parameter everywhere
Become, so that the flow area of air-flow is evenly distributed in absorption tower.Still do not break away from drop descent, gas-liquid counter current
Phenomenon, that is, it is also easy to produce reentrainment.
The demister that patent CN200920128824.1 is introduced is made up of cooler, coarse defogging device and smart demister etc., slightly
Demister is corrugated sheet or demisting plate, and smart demister is steel wire, and the demister changes traditional demister drop and air-flow side
The shortcomings that to counter-current flow, demisting efficiency is improved, but the demister structure is more complicated, and making is difficult, and as a result of
Screen net structure, demister pressure drop is larger, is also easier to block.
