These and other directional terms should not be construed as limiting terms.
Example 1:
1-6 for to the purification treatment of oil smoke, including casing 1, primary filter group 2, secondary filter 3, wherein, casing 1 is provided with the opening at its top and bottom, and its inner space has limited rising oil smoke passageway p, and the oil smoke flows from bottom to top along rising oil smoke passageway p promptly, and primary filter group 2 and secondary filter 3 set up in casing 1, and primary filter group 2 is located secondary filter 3's below for the oil smoke flows from bottom to top in-process, carries out purification filtration treatment to the oil smoke by primary filter group 2, secondary filter 3 in proper order, filters out the oily composition in the oil smoke.
The primary filter layer group 2 includes a lower filter layer 21 and an upper filter layer 22 which are spaced apart from each other, the lower filter layer 21 and the upper filter layer 22 may be provided in a plate-like structure, and the upper filter layer 22 of this embodiment is provided as one, that is, the primary filter layer group 2 of this embodiment is of a double-layer plate structure, and a plurality of upper filter layers 22 may be provided so that the primary filter layer group 2 is of a multi-layer plate structure. Be provided with a plurality of lower floor's oil smoke hole h1 on the lower floor's filter layer 21, be provided with a plurality of upper strata oil smoke hole h2 on the upper strata filter layer 22, upper strata oil smoke hole h2 and lower floor's oil smoke hole h1 stagger each other in vertical direction and arrange, oil content can be filtered respectively when oil smoke passes through primary filter layer group 2 and secondary filter 3, because secondary filter 3 is located primary filter layer group 2's top, the oil drop that forms on the secondary filter 3 can drop primary filter layer group 2, because upper strata oil smoke hole h2 and lower floor's oil smoke hole h1 stagger each other, can avoid the oil drop to directly pass lower floor's oil smoke hole h1 and drip out casing 1, then the drip is on air inlet flue or other equipment of connection casing 1, avoid taking place to wash inconvenient the condition that causes the potential safety hazard even. Because the lower-layer oil smoke holes h1 and the upper-layer oil smoke holes h2 are staggered, oil smoke can directly collide on the bottom surface of the upper-layer filter layer 22 when flowing upwards through the lower-layer oil smoke holes h1, so that an oil layer or oil drops are formed on the bottom surface of the upper-layer filter layer 22, and a preliminary purification and filtration effect on the oil smoke is achieved.
In addition, since the lower layer oil smoke holes h1 and the upper layer oil smoke holes h2 are staggered with each other, oil smoke vertically passes through the lower layer oil smoke holes h1, and is diffused to the periphery after striking the bottom surface of the upper layer filter layer 22, and vertically passes through the upper layer oil smoke holes h2, so that turbulence is formed between the lower layer filter layer 21 and the upper layer filter layer 22. Of the droplets dropped from the secondary filter 3, most of the droplets will drop directly on the top surface of the lower filter layer 21 due to gravity, whereas after a small portion of the droplets having a relatively light weight pass through the upper oil smoke hole h2, the droplets deviate from the vertically downward dropping path under the influence of turbulence and drift around, resulting in that the portion of the droplets drips to the range of the lower oil smoke hole h1 and drops from the lower oil smoke hole h 1. In addition, the oil droplets that have landed on the top surface of the lower filter layer 21 also flow around due to turbulence, and may drop from the lower soot holes h 1. Based on this, in this embodiment, the top surface of the lower filter layer 21 is provided with the oil blocking portion 21a at the periphery of the lower oil smoke hole h1, and the oil blocking portion 21a gradually bulges toward the lower oil smoke hole h1, so that the lower oil smoke hole h1 is located at a higher level, and the oil blocking portion 21a plays a role in blocking oil drops between the lower filter layer 21 and the upper filter layer 22 from dropping from the lower oil smoke hole h 1.
In this embodiment, the bottom surface of the lower filter layer 21 is provided with the flow guide portions 21b at the periphery of the lower oil smoke hole h1, the flow guide portions 21b are gradually raised away from the lower oil smoke hole h1, and based on the arrangement of the flow guide portions 21b, the lower filter layer 21 forms oil smoke passages p1 between the flow guide portions 21b on the bottom surface, the oil smoke passages p1 are used for guiding the oil smoke to flow down the lower oil smoke hole h1, i.e., when the oil smoke flows from bottom to top to the lower filter layer 21, the oil smoke is split by each oil smoke passage p1, flows along the oil smoke passages p1 and passes upward through the lower oil smoke hole h1, and the width of the oil smoke passages p1 is gradually reduced along the flow direction of the oil smoke. Firstly, since the oil smoke passageway p1 is gradually reduced from bottom to top, the oil smoke is gradually extruded by the guiding portion 21b when flowing along the oil smoke passageway p1, and the contact strength between the oil smoke and the guiding portion 21b is gradually increased under the gradually enhanced extrusion, so that the oil drop amount formed by the oil smoke on the guiding portion 21b is gradually increased, that is, the oil drop amount formed by the guiding portion 21b is larger as the oil drop is closer to the lower layer oil smoke hole h 1. Secondly, since the oil smoke passageway p1 gradually decreases from bottom to top, the flow speed of the oil smoke along the oil smoke passageway p1 gradually increases, that is, the wind force gradually increases, so that the oil drops formed on the flow guiding part 21b can flow along the flow guiding part 21b and pass through the lower oil smoke hole h1 under the gradually increasing wind force, and finally flow onto the top surface of the lower filtering layer 21, thereby avoiding the oil drops formed on the bottom surface of the lower filtering layer 21 and dripping from the bottom surface.
In this embodiment, the diversion portion 21b is divided into a first area s1 close to the lower layer lampblack hole h1 and a second area s2 far away from the lower layer lampblack hole h1, wherein the first area s1 of the diversion portion 21b is attached with a lipophilic layer, and the second area s2 of the diversion portion 21b is attached with a hydrophobic layer. Because the width of the oil smoke passageway p1 is gradually reduced along the flow direction of the oil smoke, compared with the second area s2, oil drops are easier to form in the first area s1 due to the fact that the oil smoke is matched with the lipophilic layer attached to the first area s1 and the oil-repellent layer attached to the second area s2, oil drops are more difficult to form in the second area s2, the oil drops are more close to the lower-layer oil smoke holes h1 due to the fact that the first area s1 is matched with the oil smoke passageway p1, and the wind speed is higher corresponding to the first area s1, oil drops formed on the bottom surface of the lower-layer filter layer 21 are easier to pass through the lower-layer oil smoke holes h1 and flow to the top surface of the lower-layer filter layer 21.
In this embodiment, the top surface of the lower filter layer 21 forms the oil collecting portion 21c between the adjacent oil blocking portions 21a, and since the oil blocking portions 21a gradually bulge toward the lower soot holes h1, the oil collecting portion 21c is formed into a concave structure in structure, which has the function of storing oil droplets, so that the oil droplets between the upper filter layer 22 and the lower filter layer 21, the oil droplets dropped from the bottom surface of the upper filter layer 22 and the oil droplets flowing on the top surface of the lower filter layer 21 are all collected in the oil collecting portion 21 c.
For the specific structure of the lower filter layer 21, in this embodiment, the lower filter layer 21 has a plurality of folded plates 211 formed by alternately folding, which may be flat folding or folding, so that the lower filter layer 21 presents a wavy plate structure, a crest folded angle d1 or a trough folded angle d2 is formed at the intersection of adjacent folded plates 211, the lower oil smoke holes h1 are disposed on the crest folded angle d1, that is, the lower oil smoke holes h1 are disposed in a plurality of columns, the plurality of lower oil smoke holes h1 of each column are disposed at intervals along the crest folded angle d1, and as the lower oil smoke holes h1 are disposed on the crest folded angle d1, the top surfaces of the folded plates 211 at both sides of the lower oil smoke holes h1 form oil blocking portions 21a, the bottom surfaces of the folded plates 211 at both sides of the lower oil smoke holes h1 form guide portions 21b, and the top surfaces of the trough folded angles d2 form oil converging portions 21c.
In this embodiment, the oil smoke flows from bottom to top in the rising oil smoke channel p, and flows to the lower layer filter layer 21 by the oil smoke channel p1 formed between the adjacent folded plates 211, the oil smoke continues to flow upwards along the oil smoke channel p1, the flow speed is gradually increased, the contact strength between the oil smoke and the bottom surface of the folded plates 211 is also gradually increased, oil drops are formed in the first area s1 of the bottom surface of the folded plates 211 by matching with the lipophilic layer, and after the oil drops pass through the lower layer oil smoke hole h1 upwards under the action of wind force, the oil drops flow to the top surface of the trough folded angle d2 along the top surfaces of the folded plates 211 at two sides of the upper layer oil smoke hole h 2; the oil smoke passes through the lower oil smoke holes h1 to directly strike on the bottom surface of the upper filter layer 22, and oil drops are formed, and gradually drop from the bottom surface of the upper filter layer 22, directly drop on the top surface of the trough folded angle d2, or drop on the top surface of the folded plate 211 and flow to the top surface of the trough folded angle d 2; the oil droplets filtered by the secondary filter 3 drop downwards, wherein most of the oil droplets pass through the upper-layer oil smoke hole h2 and then directly drop on the top surface of the trough folded angle d2, or drop on the top surface of the folded plate 211 and flow to the top surface of the trough folded angle d2, and a small part of the oil droplets with lighter weight drift around under the action of turbulence and are blocked and trapped by the top surface of the folded plate 211 and then flow to the top surface of the trough folded angle d2 along the top surface of the folded plate 211.
In this embodiment, the upper layer lampblack holes h2 are disposed at the position of the upper layer filter layer 22 corresponding to the trough folded angle d2, that is, the upper layer lampblack holes h2 are disposed in multiple rows and staggered with the lower layer lampblack holes h1, and since the disposed position of the upper layer lampblack holes h2 corresponds to the trough folded angle d2, most of the oil drops dropped from the secondary filter 3 can be directly dropped on the top surface of the trough folded angle d2, that is, drop on the oil collecting portion 21c.

The oil receiving structure 42 may be configured as an oil receiving plate, or may be configured as an oil receiving groove or an oil receiving shell. The oil receiving structure 42 is arranged slightly inclined, so that oil drops on the oil receiving structure 42 can be prevented from dripping into the housing 1, and the oil drops can also flow to the oil discharging structure 41.
