Cooking fume remover and negative electrode plate thereof
Technical field
The utility model relates to electrostatic method and processes oil smoke apparatus field, relates in particular to a kind of cooking fume remover and negative electrode plate thereof.
Background technology
The operation principle that electrostatic method is processed oil smoke is as follows: under the electric field forming at plus high-pressure, the wire surface of negative pole or near ejected electron are rapidly to positive polar motion, with gas molecule collision ionization.Oil flue waste gas is when this high voltage electric field, and soot particles is captured gas ion and caused chargedly in extremely short time internal cause collision, moved by electric field force effect, thereby reach separating effect to anodal collecting plate.It is low that this kind of processing mode has energy consumption, the advantage that resistance is little.
General, the internal structure of existing cooking fume remover adopts following two kinds of forms:
One, flat cooking fume remover, it utilizes high direct voltage, by the electric discharge between pole plate and utmost point magnetic, makes oil smoke molecular ionization;
Two, honeycomb fashion cooking fume remover, it is to utilize high direct voltage equally, between occurring, produces ionization by cylindrical shape anode and one and the equidistant utmost point bar of cylindrical center, makes oil smoke molecular ionization.
The clarifier of above-mentioned two kinds of structures has the following disadvantages: 1, flat cooking fume remover because of its pole plate be tabular, so windage is less, although can obtain larger suction, yet its fume purifying efficiency is low; And flat structure is stable not, often because suction is excessive, there is deformation, likely cause internal circuit short circuit, bring potential safety hazard; 2, honeycomb fashion cooking fume remover fume purifying efficiency is high, but windage is large, and energy consumption is larger, and cellular internal structure easy cleaning not.
In view of this, need badly and relate to a kind of cooking fume remover with new internal structure and solve the problems referred to above.

Further, two long edges of described substrate are respectively equipped with described sawtooth portion, and this two sawtooth portion shifts to install up and down at the length direction of negative electrode plate.
Further, the cross section of described fin is triangle.
Further, the two ends up and down of described positive electrode plate are individually fixed on the roof and diapire of internal box, and described negative electrode plate is fixed in internal box by being arranged in the insulation body of rod at its upper and lower two ends.
Two of the purpose of this utility model is to provide a kind of negative electrode plate.
For achieving the above object, the utility model adopts following technical scheme:
A negative electrode plate, has a substrate, and at least one long edge of substrate is provided with sawtooth portion, and the middle part of substrate is provided with the fin extending along its length.
Further, two long edges of described substrate are respectively equipped with described sawtooth portion, and this two sawtooth portion shifts to install up and down at the length direction of negative electrode plate.
Further, the cross section of described fin is triangle.
As mentioned above, the utility model arranges sawtooth portion by the long edge at negative electrode plate, thereby can increase point of discharge and area, the oil smoke molecule that makes to pass through obtain charged electrical from, and then reach the object that promotes clean-up effect; By set up fin on negative electrode plate, can strengthen the twisting resistance of this negative electrode plate, and then strengthen the working strength of this cooking fume remover; And whole electrode unit is tabular substantially, the square parallel setting of advancing of its plate face and oil smoke, windage is little, and energy consumption is low.

The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
Refer to Fig. 1 to Fig. 4, the utility model discloses a kind of cooking fume remover, it comprises internal box 10 and shell 20, described internal box 10 is positioned at shell 20, internal box 10 is equipped with opening with shell 20 two ends, two openends respectively correspondence are made as air inlet 11 and air outlet 12, form oil smoke passage (not indicating in figure) between this air inlet 11 and air outlet 12; In described internal box 10, be provided with some electrode units, each electrode unit comprise the positive electrode plate 31 perpendicular with the extension course bearing of described oil smoke passage with parallel with this positive electrode plate 31 over against negative electrode plate 32, described negative electrode plate 32 has a substrate 321, at least one long edge of substrate 321 is provided with sawtooth portion 322, and the middle part of substrate 321 is provided with the fin 323 extending along its length.
Particularly, in the present embodiment, internal box 10 and the shell 20 of this cooking fume remover have rectangular profile, the two ends up and down of described positive electrode plate 31 are individually fixed on the roof and diapire of internal box 10, described negative electrode plate 32 is fixed in internal box 10 by being arranged in the insulation body of rod 40 at its upper and lower two ends, the electrode unit being comprised of positive electrode plate 31 and negative electrode plate 32 is uniformly distributed in described internal box 10, and the plate face of each battery lead plate is parallel with internal box 10 two sides.
In the use procedure of clarifier, be arranged on the twisting resistance that fin 323 on negative electrode plate 32 can strengthen this negative electrode plate 32 effectively, thereby there is the phenomenon of torsional deformation in the battery lead plate of avoiding causing because suction is excessive, prevents that short circuit phenomenon from appearring in cooking fume remover; Described positive electrode plate 31 and the plate face of negative electrode plate 32 are direct of travels of parallel oil smoke, therefore, can reduce windage, thereby reduce energy consumption; By sawtooth portion 322 is arranged to at least one long edge of negative electrode plate 32, thereby can increase point of discharge (according to point discharge principle, each tip of this sawtooth portion 322 is an effective point of discharge) and area, can make to be ionized more fully by the oil smoke molecule of internal box 10, promote fume purifying effect.
Please continue and consult Fig. 3, preferably, therein in an embodiment, two long edges of described substrate 321 are respectively equipped with described sawtooth portion 322, this two sawtooth portion 322 shifts to install up and down at the length direction of negative electrode plate 32, this design can further increase the point of discharge between both positive and negative polarity, promotes fume purifying effect; Be worth mentioning, this two sawtooth portion 322 is symmetrical set also can.
Please continue and consult Fig. 4, particularly, the cross section of described fin 323 is triangle, and because leg-of-mutton structure itself has stability, so the fin 323 of this triangle can obtain the object of the described negative electrode plate of further enhancing Final 32 degree; In fact, the cross section of this fin 323 can also be that rectangle or part are oval, and it all can play the object that strengthens negative electrode plate Final 32 degree.
