Description
Technical field
The present invention relates to dust arrester technical field, relate in particular a kind of fume dust remover.
Background technology
Instantly, environmental protection has been global social concern, especially air pollution, and damaging range is large, the time is long, the extent of injury is dark.
Air pollution, mainly that the waste gas that factory emits causes, factory in process of production, a lot of boilers can give off flue gas, if these flue gases do not pass through harmless treatment, the harmful substance wherein containing, be can not directly be emitted on airborne, therefore, just there is dust arrester, utilize dust arrester that the flue dust in flue gas is removed, meet discharge standard, existing dust arrester, what much adopt is spray mode, the liquid curtain and the flue gas that by spray equipment, spray exchange, to reach the object of dedusting, patent publication No. is CN 201431840, open day a kind of fume dust remover is disclosed for the Chinese utility model patent of 2010-03-31, its bottom that is included in housing contains into mouth, gas flue, impeller dust arrester, dedusting spray equipment, liquid bath and the liquid back pipe being connected with liquid bath and confession liquid pool, dividing plate is housed in housing, top at dividing plate contains screen pack, above screen pack, be equipped with and the cleaning spraying device being connected for liquid pool, above cleaning spraying device, be shaped with exhaust opening, the spout of Flue Gas Pretreatment Device is also housed in addition, in entering mouth.But, the dust arrester of this utility model, the effect of its dedusting, removal harmful substance is poor, complicated structure.
Summary of the invention
The object of the invention is, for the deficiencies in the prior art part, provides a kind of fume dust remover, its dedusting, removes the effective of harmful substance.
In order to solve the problems of the technologies described above, technical scheme of the present invention is as follows: fume dust remover, comprise liquid storage pool, spray chamber, be positioned at described spray chamber below and be provided with the dirt pocket of exhausting window, be arranged on the spray equipment in described spray chamber, the delivery pump being communicated with described spray equipment and flue gas inlet pipe, described dirt pocket lower end is provided with soiling solution collector, described flue gas inlet pipe top is stretched in described spray chamber through described soiling solution collector, described soiling solution collector comprises the collection funnel that is fixed on described dirt pocket lower end, be fixed on the surge drum of described collection funnel lower end, be arranged on the screen pack in described surge drum and be arranged on the hydraulic seal layer on described screen pack, described surge drum is provided with the liquid return hole being communicated with described liquid storage pool that is positioned at described screen pack below.
Fume dust remover of the present invention, from flue gas inlet pipe flue gas out, when upwards wafing, contact fully with the liquid curtain of spray equipment ejection, remove flue dust and harmful substance, then flue gas is discharged from exhausting window, complete whole dedusting exchange process, the sediment of removed dust and harmful substance is filtered net and stops, screen pack is because the reason of liquid tension, can form hydraulic seal layer thereon, the aperture of thickness and screen pack is relevant, aperture more carefully, hydraulic seal layer can be thicker, otherwise, thinner, hydraulic seal layer can stop that flue gas overflows from screen pack, enter liquid storage pool, thereby assurance dust removing effects, the dust of while aids precipitation on screen pack etc., can play better filtration.
As preferably, described flue gas inlet pipe comprises straight smoke pipe, be arranged on the pipe with venthole on described straight smoke pipe top and be fixed on the tarpaulin at described pipe top.
Tarpaulin protects pipe, prevent from entering flue gas inlet pipe from spray equipment spray liquid out, make dust arrester can play better dust removing effects, because once spray liquid enters flue gas inlet pipe, after spray liquid and flue gas generation dedusting reaction, produce impurity, can affect the discharge of flue gas in flue gas inlet pipe, even stop up flue gas inlet pipe, affect the dust removing effects of dust arrester.
As preferably, described tarpaulin is spherical.
Domed tarpaulin, after can making spray liquid that spray equipment ejects contact with its outer surface, scatters and comes, and makes spray liquid and flue gas realize exchange more fully, has improved dust removing effects.
As preferably, described pipe is inverted truncated cone-shaped, and described pipe is positioned at described spray chamber.
Pipe is the quantity that inverted truncated cone-shaped has increased venthole, pipe be positioned at described spray chamber make the flue gas that draws spray chamber just and spray liquid contact, extended the time that flue gas and spray liquid exchange, improved dust removing effects.
As preferably, described exhausting window comprises and is arranged on a plurality of inclined via-holes that from inside to outside reduce highly gradually on described dirt pocket sidewall, and described inclined via-hole becomes 30-45 ° of angle with horizontal plane.
The setting of inclined via-hole, can either make flue gas to get rid of, and has extended again the time of flue gas in dirt pocket, has strengthened dust removing effects.
As preferably, also comprise flue gas guide shell, described flue gas guide shell comprises lower stationary magazine creel, is positioned at the upper guide shell in described pipe outside and stops gusset, described upper guide shell consists of a plurality of deflectors, described deflector lower end is hinged on described lower stationary magazine creel by jointed shaft, and on described jointed shaft, cover has torsion spring, described torsion spring one end to act on described deflector outer surface, the other end acts on described lower stationary magazine creel inner surface, described in stop that gusset contacts with described deflector inner surface.
Upper guide shell is arranged on pipe outside, pipe is surrounded, like this, the flue gas of discharging from pipe can act on guide shell, and upper guide shell is to consist of a plurality of deflectors, that is to say, flue gas can act on deflector, overcome the power of torsion spring, can produce an outside swing, flowing of flue gas, be actually a dynamic flow process, its power acting on deflector also changes, this just makes deflector can carry out a small swing always, this swing can make flue gas upwards faster, also make the more even of flue gas mixing, improved dust removing effects.
As preferably, described flue gas guide shell is inverted truncated cone-shaped, and the under shed width that forms of described lower stationary magazine creel lower end and described straight smoke pipe is less than the width of described upper guide shell upper end and the upper shed of described pipe formation.
Under shed wants narrower with respect to upper shed, has guaranteed that flue gas overflows from upper shed, improves dust removing effects.
As preferably, described surge drum is provided with filter screen replacement mouth, on described filter screen replacement mouth, seal cover is installed.
Filter screen replacement mouth is used for changing screen pack, guarantees the operating efficiency of whole dust arrester.
As preferably, described filter screen replacement mouth lowest part exceeds described hydraulic seal layer upper surface.
Filter screen replacement mouth lowest part exceeds described hydraulic seal layer upper surface, like this, just does not need to consider the fluid tightness of seal cover, only need flue gas sealing just passable, reduced cost and manufacture difficulty, guaranteed the integrality of hydraulic seal layer, and then improved dust removing effects.
As preferably, described liquid storage pool is provided with the dividing plate that described liquid storage pool is divided into sedimentation basin and clean solution tank, and the import of described delivery pump and clean solution tank are communicated with, and described dirt pocket is communicated with described sedimentation basin.
Used liquid is through after sedimentation basin precipitation, then enters clean solution tank, and impurity is few, has guaranteed the normal work of delivery pump, has reduced the phenomenon that spray equipment stops up, and has guaranteed the effect of dedusting.
Beneficial effect of the present invention is:
Dust arrester of the present invention, its good dedusting effect, efficiency are high.
