The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and 2, an environment-friendly oil fume treatment pipeline comprises an oil hood 1, a filter device 2 and a fume exhaust pipe 3, wherein the oil hood 1 is connected with a short pipe I11, the filter device 2 is connected with a short pipe II 21 and a short pipe III 24, the short pipe I11 is provided with an inward arc angle I111, the short pipe II 21 is provided with an arc angle II 211 matched with the arc angle I111 for connecting the short pipe I11 and the short pipe II 21, the short pipe III 24 is provided with an inward arc angle III 241, and the fume exhaust pipe 3 is provided with an arc angle IV 31 matched with the arc angle III 241 for connecting the short pipe III 24 and the fume exhaust pipe 3.

Through the technical scheme, in the process of discharging the oil fume, the oil fume firstly enters the filtering device 2 through the oil cover 1, is filtered and purified by the filtering device 2 and then is discharged from the smoke exhaust pipe 3, when the filtering device 2 is used for a long time, the filtering device 2 needs to be cleaned regularly, when the filtering device 2 is disassembled, the filtering device 2 only needs to be pulled out from the short pipe I11 and the smoke exhaust pipe 3 and then is cleaned, when the filtering device is installed, only the short pipe II 21 needs to be clamped with the short pipe I11, the arc angle I111 is matched with the arc angle II 211, the short pipe III 24 is clamped with the smoke exhaust pipe 3, the arc angle III 241 is matched with the arc angle IV 31, because the oil cover 1 and the filtering device 2 are light in weight, the situation that the short pipe I11 is separated from the short pipe II 21 and the short pipe III 24 is separated from the smoke exhaust pipe 3 due to the gravity problem can not occur in the use process, no fixing piece for connection exists, the operations of disassembly and assembly are simplified.

The oil cover 1 is in a frustum shape, the oil cover 1 is welded with the first short pipe 11, and the filtering device 2 is connected with the second short pipe 21, the filtering device 2 and the third short pipe 24 in a welding mode.

Through the technical scheme, the oil cover 1 in the shape of the frustum is favorable for collecting oil smoke, the oil cover 1 is welded with the first short pipe 11, the filtering device 2 is welded with the second short pipe 21, and the filtering device 2 is welded with the third short pipe 24, so that the connection of the oil cover 1 and the first short pipe 11, the filtering device 2 and the second short pipe 21, and the filtering device 2 and the third short pipe 24 is firmer, and the oil cover has good air tightness.

The filter device 2 comprises a shell 25, a first filter screen 22 and a second filter screen 23, wherein the first filter screen 22 is bonded with the inner wall of the shell 25, the second filter screen 23 is bonded with the inner wall of the shell 25, the first filter screen 22 is of a net structure made of asbestos materials, and the second filter screen 23 is made of multiple layers of activated carbon cotton.

According to the technical scheme, after the oil smoke enters the filter device 2, the oil smoke is filtered and purified through the first filter screen 22 and the second filter screen 23, because asbestos has high fire resistance and thermal insulation, the first filter screen 22 which is made of asbestos materials and has a net structure can adsorb oil and prevent an oil smoke pipeline from sucking open fire to cause fire, and the second filter screen 23 is made of multiple layers of activated carbon cotton, effectively adsorbs and purifies chemical substances such as aldehyde, ketone and hydrocarbon in the oil smoke, and purifies the discharged oil smoke.

The inner wall of the shell 25 is sprayed with nano self-cleaning paint.

Through the technical scheme, the nano self-cleaning coating sprayed on the inner wall of the shell 25 is ZS-511 model of the Shisheng Weihua brand, so that the inner wall of the shell 25 has strong hydrophobic and oil stain resistant capabilities, and the efficiency of cleaning the oil fume treatment device is improved.

The first filter screen 22 and the second filter screen 23 are conical in shape.

Through the technical scheme, the first filter screen 22 and the second filter screen 23 are conical, so that the contact area between the oil smoke and the filter screens is increased, and the oil smoke filtering efficiency and effect are improved.

Rubber pads are arranged on the surfaces of the first arc angle 111 and the fourth arc angle 31.

Through the technical scheme, the rubber pads are arranged on the surfaces of the first arc angle 111 and the fourth arc angle 31, when the first arc angle 111 is attached to the second arc angle 211, and the third arc angle 241 is attached to the fourth arc angle 31, the rubber pads can increase the friction coefficient between the attachment surfaces, so that the first short pipe 11, the second short pipe 21, the third short pipe 24 and the smoke exhaust pipe 3 are connected more tightly and firmly, and the situation that the first short pipe 11 is separated from the second short pipe 21 and the third short pipe 24 is separated from the smoke exhaust pipe 3 is avoided.

After the first arc angle 111 and the second arc angle 211 are attached, one end of the first short pipe 11, which is far away from the oil cover 1, contacts the filtering device 2, after the third arc angle 241 and the fourth arc angle 31 are attached, one end of the smoke exhaust pipe 3 contacts the filtering device 2, sealing rings 4 made of rubber materials are arranged inside the second short pipe 21 and the third short pipe 24, and the sealing rings 4 are tightly attached to the filtering device 2.

Through above-mentioned technical scheme,

pipe

11 and 3 contact filter equipment 2 of discharging fume of nozzle stub reduce the area of pipe stub two 21, pipe stub three 24 and oil smoke contact, reduce abluent area, improve clean efficiency, set up the sealing washer 4 of rubber material at filter equipment 2's both ends, increase filter equipment 2 and pipe 11 of nozzle stub, filter equipment 2 and the coefficient of friction of discharging fume 3, improve coupling portion's gas tightness, avoid not passing through the oil smoke of purification directly to discharge in the air through the gap.

And a fan 5 is arranged at one end of the smoke exhaust pipe 3 far away from the oil hood 1.

Through above-mentioned technical scheme, set up fan 5 in the one end that tub 3 kept away from oil cover 1 of discharging fume, improve oil smoke exhaust efficiency.
