Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
As shown in fig. 1 to 4, the utility model provides a residential flue oil smoke filtering device, which comprises an exhaust duct 1 installed on a residential building, wherein a hood 2 is installed at the top of the exhaust duct 1, and the flow speed of oil smoke in the exhaust duct 1 can be increased through the rotation of the hood 2; an oil fume purification device 3 for filtering oil fume is arranged between the exhaust pipeline 1 and the blast cap 2, the oil fume in the exhaust pipeline 1 is filtered through the oil fume purification device 3, the oil fume emission amount reaching 32 percent can be filtered, and the oil fume amount exhausted into the air is effectively reduced; the oil fume purification equipment 3 comprises a box body 31 with an opening at the upper end and two filter screen plates 32, wherein the two filter screen plates 32 are fixedly connected in the box body 31 and form a V-shaped structure; the detachable top cover 33 is arranged on the box body 31, the top cover 33 is used for installing the hood 2, the top cover 33 comprises a cover shell 331 buckled on the box body 31, a positioning pipe 332 protruding upwards and used for installing the hood 2 is arranged on the cover shell 331, the cover shell 331 is fixed on the box body 31 through screws, and the hood 2 is installed and positioned through the positioning pipe 332, so that the hood 2 can be kept concentric with the exhaust pipeline 1 after being installed, and micro resistance is formed in the oil smoke flowing process; the bottom of the box body 31 is provided with a through hole 310, and the through hole 310 is communicated with the exhaust pipeline 1; the filter screen plate 32 comprises a fixed frame 321 formed by enclosing 4 frame frames with groove structures, a plurality of layers of sequentially laminated woven meshes 322 are arranged in the fixed frame 321, and each layer of woven mesh 322 is mainly formed by criss-cross weaving of a plurality of woven wires 323 with wave structures; after each weaving silk 323 contacts with the oil smoke, oil gas molecules are adsorbed onto the weaving silk 323 and gradually form oil drops, and the weaving nets 322 are woven from the cross to the cross through the weaving silks 323, so that the contact probability of the oil smoke and the weaving silks 323 is increased, and the condition that resistance cannot be generated when the oil smoke passes through is ensured.
The weaving wires 323 are made of stainless steel or aluminum, so that the slag cannot be corroded and removed in the long-term use process, and the weaving wires have good heat-conducting performance and can improve the contact liquefaction of oil gas molecules.
In order to prolong the contact time of the oil smoke passing through the filter screen plate 32, the thickness of the layers of the woven meshes 322 is 30 mm-60 mm, and the meshes of each layer of the woven meshes 322 are in a staggered installation state, so that a zigzag flowing air channel is formed, and the contact time of the oil smoke is prolonged.
