Description
Technical field
The present invention relates to dedusting, except wet goods cleaner air package technical field, more specifically, relate to and get rid of alopecia areata leaf and manufacture method thereof for cooking fume remover.
Background technology
In recent years, the living standard of people improves constantly, and healthy and environmental consciousness strengthens day by day, and people thirst for having a health, clean, the family kitchen environment of environmental protection.Meanwhile, catering industry also flourish, it bringing about a prosperous economy, improve in living standard and played positive effect.But the pollution of cooking fume to nearby residents living environment in family kitchen and food and drink hotel increasingly sharpens.In prior art, be used as the interception clarifier on dedusting air cleaning device at present, mainly contain two kinds of structures.
The first structure is dynamic oil smoke clarifier, it comprises wheel skeleton and wire, described wire generally adopts diameter to be steel wire or the B alloy wire of 0.1 ~ 0.2mm, being wrapped in by certain requirement describedly takes turns on skeleton, and the concrete structure of this dynamic physical shielding purifier and winding method can see the preparation methods of air dust centrifugal purifier disclosed in dynamic physical shielding purifier disclosed in Chinese patent literature CN200984483Y and Chinese patent literature CNl01028575A and rotary filter net disk thereof.The defect of the dynamic physical shielding purifier of this structure is apparent.First, because this dynamic physical shielding purifier comprises wheel skeleton and wire, and to take turns skeleton be make of aluminum alloy materials, its cost is higher, in addition, eachly take turns the spoke that skeleton at least comprises more than 6, spoke itself can produce windage to the air intake of air assembly, affect the purifying rate of air assembly; In addition, the wire of this clarifier is wrapped on wheel skeleton, and because wire is wrapped on wheel skeleton by needs, described diameter wiry can not be too thick, generally be 0.1 ~ 0.2mm, otherwise wire diameter too slightly just cannot be wound around; The second, because wire is comparatively thin, so the wire that there will be the clarifier at high temperature easy loose and problem that disconnects, cause the service life of clarifier short; 3rd, because wire is when being wound around, the cylindrical of its center at clarifier and wheel skeleton can form cross-like, and oil smoke very easily forms blocking at this two place, not easy cleaning; 4th, because wire is comparatively thin, it is less to the interception probability of the particle in waste gas, therefore purifying rate is low, weak effect and adaptive surface is narrow.
The structure of the second clarifier,, by the method for punching press, one circular plate-like shape thing is radially had groove, make the part between two grooves become spoke, multiple spoke distributes successively and forms on the periphery of plate object, and particular content can see Chinese patent literature CN2901109Y.The subject matter of the dynamic physical shielding purifier of this structure is that purifying rate is very low, and windage is large, and practical application function is very micro-.This is because the front of the spoke of the dynamic physical shielding purifier of this structure and two side are plane, when front is plane, its windage is large, reduces the purifying rate of clarifier; And its side is plane, when clarifier High Rotation Speed, side can produce pressure to the waste gas of coming in from frontal, under the effect of side, make waste gas along with the flowing of clarifier direction of rotation, and the chance that the particle in waste gas contacts with spoke is less, so purifying rate is low.
Therefore, no matter the existing interception clarifier be used as on dedusting, oil removing cleaner air package is adopt which kind of structure, and its purification efficiency is low, and clean-up effect is undesirable.

T
qfor waste gas is by the time (second) of the blade operation plane of clarifier;
T is running on the time needed for the angle between two adjacent blades (second) for single blade.
(formula two) t
q=d/U(second)
In formula two: D is the thickness (millimeter) of blade; U
qfor the flow velocity (mm/second) of waste gas.
(formula three) t=a/U
In formula three: a is the angle angle (week) of adjacent two blades of clarifier, a=1/n(week), wherein, n is the number of blade on clarifier same plane; U is the motor speed (cycle per second) driving clarifier to rotate.
Formula two and formula three are substituted into formula one respectively, draw after simplification:
