Abstract

The utility model relates to a fin attached type fume purifying device, which is characterized in that a plurality of fins are arranged in a pipe-shaped fume channel with certain regulation, so a high efficient fume blocking component is formed, and meanwhile, the fins can be used as adhesive objects of fume particles. When the fume enter the pipe-shaped fume channel, on one hand, the fume particles can naturally condensate in the process of flowing, and on the other hand, the fume particles can crash with the surfaces of the fins. Owing to the strong attachment property of the fume particles, the fume is easy for attaching and forming oil film on the fin surfaces after crash, so the fume particles in the fume can be separated, and the utility model can get the purpose of purifying.

Description

Fin adhesion type fume purifier of fume

The utility model belongs to a kind of filtering type that adheres to and removes fume purifier of fume, specifically: relate to a kind of a kind of range hood that the oil smoke that is produced in the cooking environments such as family, restaurant, restaurant can be carried out purified treatment.

Smoke exhaust has and uses history for many years, and it is only arranged oil smoke and does not remove owing to the reason on the project organization, uses the central time long slightly, the interior grease of ubiquitous machine promptly occurs and need remove and the exhaust opening secondary pollution problem." filter net type " smoke exhaust has appearred for this reason in recent years, its scheme just installs the various forms filter screen additional on blower fan enters a certain position of front end of mouth, filter the mist of oil particulate in the oil smoke, to reach the purifying oil fume purpose, this scheme is from practical effect, can only temporarily slow down the pollution of oil smoke to machine intimate, simultaneously because the mesh of filter screen is too little, the grease flowability that in addition leaches is very poor, cause the filter screen mesh to be stopped up by grease gradually, air drag increases thereupon, reduced the smoke exhaust efficiency of smoke exhaust, and stopped up later filter screen and need often clean or change, not only increased expense and the time of user the machine maintenance maintenance, and cumbersome, effect is not very good.

In view of the above-mentioned main shortcoming that smoke exhaust exists, the purpose of this utility model is to provide a kind of fume purifier of fume with following characteristics:

1. change oil smoke filtering mode, the filtering net part that cancellation easily makes air drag change, it is smooth and easy mobile both to have helped flue gas, convenient again daily operation and maintenance;

2. possess higher oil removal rate, the secondary pollution that reduces exhaust opening to be meeting the environmental protection trend, and realizes the grease release of machine intimate in the phase at design service life;

3. simple in structure, easily combine with the advantage of existing smoke exhaust, constitute novel practical product---range hood with fume purifying function.

For achieving the above object, the utility model mainly is made up of tubulose flue, fin, poly-oil sump, oil guide pipe and catchment cup.Its architectural feature is: be arranged with some fins according to certain rule in the tubulose flue, be used to constitute oil smoke retardance parts and adhere to the mist of oil particulate.Its basic principle is: utilize the stronger characteristics of mist of oil particulate adhesive force in the oil smoke, the method for adhering to by natural condensation and fin is separated the mist of oil particulate in the oil smoke, makes it to reach the purpose of purification.

When in the tubulose flue, flowing and effective contact area of fin surface, reach the purpose of isolating the mist of oil particulate more efficiently in order to improve the mist of oil particulate.The arrangement regulation of fin is: the longitudinal centre line of every fin cross section parallels with the axis of tubulose flue; Every row's fin is formed array according to the arrangement mode of " laterally parallel, vertically staggered ".Simultaneously, attached to fin surface, improve the deposit efficiency on the fin unit are for the ease of the mist of oil particulate, fin surface can be made light face, hair light face, pockmark face, micropore face.

The geometry of this outer tubular flue cross section can be: circular, oval, square, rectangle, polygon; The geometry of fin cross section can be: in-line, triangle, semicircle, circular arc, streamlined, so that adapt to different applied environments.

The below detailed description of doing by specific embodiment and accompanying drawing for the utility model, wherein:

Fig. 1 is the utility model basic structure schematic diagram.

The range hood fundamental diagram of Fig. 2 for adopting the utility model to constitute.

For example shown in Figure 1, the utility model is to be made of following parts: tubulose flue 1 is the thin-walled tubular object of both ends open, the passage that its oil smoke flows, and head one end is for advancing mouth, and afterbody one end is an exhaust opening; Fin 2 is streamlined sheet material for cross section, forms array according to above-mentioned arrangement regulation in tubulose flue 1, constitutes the attachment that oil smoke blocks parts and becomes the mist of oil particulate; Poly-oil sump 3 be the recess container, places below the afterbody of tubulose flue 1, and the container center position has a hole to link to each other with oil guide pipe 4, is used for assembling the fluid separated and it is imported to catchment cup 5.

Its operation principle is: after oil smoke enters tubulose flue 1 by direction as shown, the mist of oil particulate in flow process on the one hand in natural condensation, then bump on the other hand with the surface of fin 2, because the mist of oil particulate has stronger tack, when collision, very easily form oil film in fin 2 surface attachment, along with the mist of oil particulate constantly collides and adheres to, oil film thickening gradually finally forms fluid, fluid is under the double action of self gravitation and wind-force, flow to the poly-oil sump 3 of tubulose flue 1 afterbody, flow in the catchment cup 5 by oil guide pipe 4.In like manner, because oil smoke constantly bumps with each row's fin 2 in flow process, this just makes mist of oil particulate wherein make that the mist of oil particulate in the oil smoke flows along with oil smoke and little by little minimizing, and to be purified fully attached to fin 2 surfaces.Clean gas after the purification is discharged by tubulose flue 1 afterbody.

Because the sheet and the sheet horizontal spacing of every row's fin 2 are bigger, therefore the incident grease clogging of similar filtering net part can not occur in addition, realize and needing to have avoided the frequent worried problem of cleaning or changing filtering net part again by purifying oil fume.

Need to prove that the utility model only is a fume purifier of fume, and passive delivery own, therefore can not use as independent fume purifying utensil.Having only when it combines with other parts to become the range hood that has on the Practical significance, embodies the function of purifying oil fume.

For example shown in Figure 2, be a typical range hood that adopts the utility model to constitute.It is by the basic element of character: exhaust fume collecting hood 6 oil smoke capturing devices, the utility model 8 fume purifier of fume, centrifugal blower 9 oil fume pump exhaust devices constitute.Its course of work is: after cooking fume is captured by exhaust fume collecting hood 6, enter into the utility model 8 and carry out purified treatment through advancing mouth 7, handle the air outlet 10 of back clean gas by centrifugal blower 9 and be discharged in the atmosphere.And the cleaning principle and the course of work, the front has explained and has repeated no more.

Verify on the spot according to the model machine that the utility model is made: cooking fume is handled the most mist of oil particulates in back through range hood and is cleaned, and in the middle of the process on probation of some months, the air outlet 10 of centrifugal blower 9 does not see that obvious greasy dirt exists.

Adopt range hood of the present utility model in addition, installation, use and common deep layer type smoke exhaust are basic identical, do not need additionally to add any specific condition.
