Background technology
At present, various boiler, these boiler oils can all be used in industry processes and in people's daily life
Large quantity of exhaust gas can be released in combustion, be directly discharged in environment if these waste gas are unprocessed, the life of people can be given
Live and the environment of work causes the biggest harm, but existing dust-removing device for boiler is unreasonable because of the design of its structure, can not
Thoroughly remove the waste gas that boiler combustion produces, and these waste gas are often required for carrying out desulphurization denitration operation, in wet desulphurization
Cheng Zhong, former flue gas reacts removing SO2 in absorption tower, then mixes droplet and portion with the lime stone slurry sprayed through spraying layer
The flue gas of point particulate matter again after demister is except mist through air flue emission.Owing to smoke components is complicated, after spraying layer, still can carry
A large amount of droplets and particulate matter.The bending channel that flue gas consists of demister corrugated sheet with certain speed, at inertia force and weight
Under the effect of power by the drop carried secretly in air-flow and particulate separation out, fall in slurry pool, it is achieved that gas-liquid separation, make
Must flow through and discharge after the flue gas of demister reaches to require except mist.If but flue gas particles is many, complicated component is easily at demister ripple
Shape plate encrustation, affects demisting efficiency.And the general volume of demister is relatively big, changes maintenance complexity, affect bulk devulcanization tower
Desulfuration efficiency.Simultaneously because spraying layer and the back purge system of demister, also can make to carry a large amount of steam in flue gas, steam carries
The a small amount of SO2 not absorbed by spraying layer or fine particle are with cigarette airflow exits, thus reduce demisting efficiency.And existing spray
Tower its nozzle of its spray equipment is fixed, and surrounding is sprayed water, sometimes because of nozzle setting angle, and nozzle processing technique defect, hydraulic pressure
Low and the problem of water quality, is difficult to find itself intrinsic problem after equipment installs, after coming into operation, often goes out
Current situation portion ash-removal effect difference and the problem such as water consumption is bigger.

Being provided with spout hole, spout hole lower end connects back to flow tube, is provided with cover cylinder inside annular bottom plate, and cover cylinder centre is provided with blind plate,
Being connected by the swirl vane of some inclinations between blind plate with cover cylinder, the flue gas forming inclination between adjacent two pieces of swirl vanes leads to
Road；Described swirl-flow devices be arranged over baffle plate, baffle plate is obliquely installed, and the top of baffle plate is provided with filter chamber, and filter chamber passes through
Conduit is connected with catalyst chamber；Described catalyst chamber is provided above the first filter course, and the first filter course is provided above the second mistake
Filtering layer, the second filter course is provided above demister, and the top of tower body offers exhaustor.
As further program of the utility model: described swirl vane is 25 ° with the angle of horizontal plane.
As this utility model further scheme: described first filter course is that stainless steel silk braiding forms, and is net
Shape structure.
As this utility model further scheme: be filled with granular active carbon inside described second filter course.
Compared with prior art, the beneficial effects of the utility model are: this utility model is simple and reasonable, user
Just, swivel nozzle core rotates, while by being arranged on the oblique hole for water spraying of swivel nozzle in-core by water mists after atomization at a high speed
Ejection, pressure is strong, and spraying effect is good；Owing to swirl vane is to tilt, define between two pieces of the most adjacent swirl vanes
One flue tilted, just creates rotary motion when the flue gas after spray is again by swirl-flow devices, the mist being mingled with in flue gas
Foam is just thrown toward cover cylinder inwall and flows down, when mist is more overflow from cover cylinder time, the mist of spilling is along spout hole and return duct
Flow down, it is to avoid mist enters demister affects demisting efficiency, thus improves desulfuration efficiency；Filter chamber passes through conduit with many
Individual catalyst chamber is connected, and waste gas is dispersed, carries out purification filtering, effectively go in removing exhaust gas in different catalyst chamber
Harmful substance, thus substantially increase work efficiency.
