Abstract

The utility model relates to an electronic fume filter, mainly comprising a set of positive or negative discharge electrodes, a negative or positive porous pole plate, etc. which are arranged in an insulated box body. The utility model is arranged in a fume inlet of a fume exhaust fan. When DC high voltage or pulsation high voltage is applied between the discharge electrodes and the porous pole plate, a corona zone with positive and negative gas ions can be formed around the discharge electrodes. Thus fume particles can be captured by the porous pole plate after charged, air stream can be purified, the fume can not enter an inner chamber, an air channel, etc. of the fume exhaust fan, and users need not to frequently dismount and wash the fume exhaust fan. Meanwhile, the utility model can reduce the quantity of fume exhausted to the atmosphere and is profitable for protecting environment, and the utility model can be popularized and used in fume exhaust fans or devices, the air streams of which need purifying.

Description

The electronics cooking fume filter

The utility model relates to the filter that dispersed granules is separated from gas, especially a kind of electronics cooking fume filter.

In the prior art, traditional kitchen hood does not generally have lampblack filter, or only adopts porous flat plate to collect the part oil smoke.Therefore, after kitchen hood was using longer a period of time, its inner chamber, air channel, impeller, exhaust passage, outlet grid etc. were all stain by oil smoke; When serious, the gas friction in the time of can causing wheel rotation increases, and motor load increases, and rotating speed reduces, and the ability of fume exhaust is reduced greatly; Sometimes outlet grid is difficult to open because of by oil smoke and dust adhesion, and influence is used normally.For this reason, the user has to unload the goods from the airplane and unpicks and washes, and not only time-consuming but also require great effort, very trouble has been unpicked and washed often, the parts of also easy damage machine.Particularly in the restaurant, the kitchen hood that uses such as dining room, hotel, bigger because of its oil smoke amount, not only polluted the place of cooking work, oil smoke discharge in atmosphere, the environment around also having polluted.

In view of the foregoing, the purpose of this utility model is: develop a kind of electronics cooking fume filter by the high voltage electrostatic field purifying oil fume, can solve problems of the prior art.

For achieving the above object, the technical solution adopted in the utility model is: the monoblock that it is included in the insulation casing has on the dividing plate of passage, one group of just discharge electrode of (or negative) is housed, in air flow outlet one side of discharge electrode the porous pole plate of negative (or just) is housed, the high pressure leader of a porous pole plate and the high pressure leader of a discharge electrode are housed in the side of casing.

Below in conjunction with accompanying drawing,, provide details of the present utility model by the description of embodiment.

Description of drawings:

Fig. 1. structure principle chart of the present utility model;

Fig. 2. the utility model level is installed in the position view in the kitchen hood;

Fig. 3. the utility model is vertically mounted on the position view in the kitchen hood.

As shown in Figure 1, it comprises a kind of electronics cooking fume filter, it is characterized in that it comprises: the monoblock in insulation casing 2 has on the dividing plate of passage, one group of just discharge electrode 4 of (or negative) is housed, in the air-flow a exit of discharge electrode 4 side porous pole plate 5 of negative (or just) is housed, the high pressure leader 6 of a porous plate 5 and the high pressure leader 7 of a discharge electrode 4 are housed in the side of casing.In the air-flow a porch of casing 2, the high voltage protection grid made from insulating materials 1 that have passage are housed.Discharge electrode 4 adopts metallic conduction pin or conducting strip.Porous pole plate 5 adopts sheet metal or woven wire.

Operation principle of the present utility model is as follows: between the discharge electrode 4 that just is being applied to (or negative) when high voltage direct current or high-pressure pulsating voltage and the porous pole plate 5 of bearing (or just), just between positive and negative polarities, formed the high-voltage electrostatic field, when voltage reaches certain value, form the corona zone that contains positive and negative gas ion in discharge electrode 4 peripheral regions of (or negative) just.When the air-flow a that contains oil smoke passes through this corona zone, will be by charged, be that soot particles has positive charge or negative electrical charge, charged soot particles is under high voltage electrostatic field, to be caught by negative (or just) porous pole plate 5, the air-flow b that flows out from negative (or just) porous pole plate 5 just is cleaned like this, thereby reaches the purpose of removing oil smoke in the air-flow.

Guard boom 1 must be made with insulating materials, in case people or thing touch high voltage component, its structure can be independently, also can make one with casing 2.Casing 2 also must be made with insulating materials, will have certain mechanical strength and rigidity simultaneously.Conductor 3 is in order to connect all just discharge electrodes 4 of (or negative).High pressure leader 7 and high pressure leader 6 adopts the material of good conductivity to make, and high direct voltage or pulsation high-tension electricity guided on the porous pole plate 5 of the discharge electrode 4 of just (or negative) in the casing 2 and negative (or just).

As shown in Figure 2, the utility model level is installed in the position in the kitchen hood, the air-flow a that contains oil smoke at first enters the electronics cooking fume filter from the kitchen hood below, just the porous pole plate 5 of the discharge electrode 4 of (or negative) and negative (or just) all should keep a rational inclination angle with horizontal direction, can flow in the lubricating cup that sets in advance behind the fluid so that the oil smoke that captures congeals into, the air-flow b of the cleaning behind the removing oil smoke just enters impeller, inner chamber and the air channel etc. of kitchen hood.

As shown in Figure 3, the utility model is vertically mounted on the position in the kitchen hood, and the air-flow a that contains oil smoke at first enters the import air channel from the kitchen hood below, enters the electronics cooking fume filter after turning round again, can go in the lubricating cup by the deadweight water conservancy diversion of fluid.Just the discharge electrode 4 of (or negative) all can be parallel with guard boom 1 with the porous pole plate 5 of negative (or just).The air-flow b of the cleaning behind the removing oil smoke just enters impeller, inner chamber and the air channel etc. of kitchen hood.

The utility model compared with prior art its advantage is: adopt electronic fume filter to be contained in suction oil The oil smoke porch of cigarette machine, the air-flow that contains oil smoke just are captured during by the high-voltage electrostatic field, and no longer enter suction The inner chamber of smoke exhaust, air channel etc., the user does not need often to unpick and wash kitchen hood, makes the fume exhaust function long The phase steady operation keeps the ability of normal fume exhaust, greatly reduces the oil smoke amount that enters atmosphere, and is favourable In protection of the environment. Therefore, the utility model can or need at kitchen hood to push away in the equipment of purifying gas flow The wide use.
