Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0021] In the actual use process of the existing flue, the oil fume will be directly discharged into the flue, which will produce oil stains and mix with the dust in the flue. Over time, it will cause the flue to be difficult to clean, and thus cause serious safety hazards. At the same time, a large amount of polluted gas will be discharged outdoors during the emission, which not only endangers people's health but also affects the air environment.

[0022] In view of this, the utility model provides an environment-friendly flue structure for buildings. Through the cooperation between the first servo motor, rotating rod, impeller, oil collecting cover, condenser tube and oil sump, the rapid separation of oil fume discharged from the flue is realized, and the grease in the oil fume is collected, solving the problem that the oil fume will be directly discharged into the flue, producing oil stains and mixing with the dust in the flue, which causes the flue to be difficult to clean over time and thus causes serious safety hazards.

[0023] By those skilled in the art, the components in this case are connected in sequence. For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0024] Embodiment 1: Consisting of Figures 1-4It can be seen that an environment-friendly flue structure for buildings includes a smoke guide pipe 1. A smoke inlet pipe 26 is installed on the front of the smoke guide pipe 1. The smoke inlet pipe 26 can be connected to the air outlet end of the oil fume exhaust equipment in the building, and the oil fume enters from here. One side of the smoke guide pipe 1 is communicated with a connecting pipe 21. The end of the connecting pipe 21 is communicated with a box body 8. A smoke outlet pipe 27 is installed on the top of the box body 8. A first filter screen 9 is fixedly connected to the inner wall of the smoke outlet pipe 27. The function of the first filter screen 9 is to prevent dust from entering the box body 8 from the outside. A fume separation mechanism is arranged inside the smoke guide pipe 1. The fume separation mechanism includes a first servo motor 2, a rotating rod 3, an impeller 4, an oil collecting cover 7, a condensation pipe 5 and an oil collecting tank 6. The first servo motor 2 is installed on the side of the smoke guide pipe 1 away from the connecting pipe 21. The model of the first servo motor 2 is not limited. The output end of the first servo motor 2 is fixedly connected to a rotating rod 3. The rotating rod 3 passes through the outer wall of the smoke guide pipe 1 through a sealing bearing. A plurality of impellers 4 are installed on the outer wall of the rotating rod 3 on the side inside the smoke guide pipe 1. A condensation pipe 5 is arranged on the side of the rotating rod 3 away from the first servo motor 2. The outer wall of the condensation pipe 5 is fixedly connected to the inner wall of the smoke guide pipe 1. An oil collecting tank 6 is arranged below the rotating rod 3. The top of the oil collecting tank 6 is fixedly connected to the bottom of the smoke guide pipe 1. An oil collecting cover 7 is fixedly connected to the inner wall of the oil collecting tank 6. A filter cloth made of polypropylene oil-absorbing cotton can be arranged on the oil collecting cover 7, which has lipophilicity. The formed filter cloth has the performance of adsorbing oil and has better oil removal and filtration efficiency, and can adsorb oil;

[0025] In the specific implementation process, it is particularly worth noting that the condensation pipe 5 is obliquely arranged in the smoke guide pipe 1. Under the rotation of the impeller 4, the discharge of the fume can be accelerated, the efficiency can be improved, and at the same time, it can drive the fume to flow in the inclined downward direction. Part of the oil in the fume is collected into the oil collecting tank 6 by the oil collecting cover 7 under the influence of gravity, and the other part of the fume can also better contact and cool with the condensation pipe 5 and flow into the oil collecting tank 6 under the influence of gravity;

[0026] Furthermore, a first water pump 11 is fixedly connected to the top of the box body 8. The model of the first water pump 11 is not limited. The output end of the first water pump 11 is communicated with a spray pipe 22. The spray pipe 22 penetrates through the outer wall of the box body 8 and extends into its interior. A spray head 23 is installed on the side of the spray pipe 22 inside the box body 8 close to the connecting pipe 21;

[0027] In the specific implementation process, it is particularly worth noting that the water flow through the spray pipe 22 forms a water mist from the spray head 23 to capture dust, dirt, etc. in the box body 8;

[0028] Furthermore, an oil outlet pipe 18 is installed at the bottom of the oil collecting tank 6. A control valve 20 is installed below the oil outlet pipe 18 and on the oil outlet pipe 18;

[0029] In the specific implementation process, it is particularly worth noting that the control valve 20 is usually in a closed state. When the waste oil in the oil collecting tank 6 is collected to a certain extent, the control valve 20 is opened to allow the waste oil to be discharged from the outlet pipe 18.

[0030] Furthermore, a second water pump 15 is arranged above the smoke guide pipe 1. The model of the second water pump 15 is not limited. The input end of the second water pump 15 is communicated with a water storage tank 19, and the output end of the second water pump 15 is communicated with a water inlet pipe 16. The water inlet pipe 16 penetrates through the outer wall of the smoke guide pipe 1. One end of the water inlet pipe 16 located inside the smoke guide pipe 1 is communicated with the condensation pipe 5, and the end of the condensation pipe 5 is communicated with a water outlet pipe 17. The water outlet pipe 17 penetrates through the inner wall of the smoke guide pipe 1, and the end of the water outlet pipe 17 is communicated with one side of the water storage tank 19 far from the second water pump 15. A heat sink 10 is arranged on the top of the water storage tank 19. The heat sink 10 can be made of aluminum alloy material, which has good heat dissipation performance and is corrosion-resistant.

[0031] In the specific implementation process, it is particularly worth noting that by starting the second water pump 15, the water in the water storage tank 19 passes through the water inlet pipe 16, the condensation pipe 5 and the water outlet pipe 17 in sequence and then returns to the water storage tank 19. The purpose of this design is to keep the water temperature in the condensation pipe 5 at a constant temperature through the flow of water, and at the same time, the heat sink 10 can accelerate the heat dissipation of the water in the water storage tank 19.

[0032] Furthermore, a heat insulation layer 14 is arranged on the top of the smoke guide pipe 1. The top of the heat insulation layer 14 is fixedly connected to the bottom of the water storage tank 19. A water inlet pipe 12 is installed on the top of the water storage tank 19, and a dust-proof net 13 is fixedly connected to the inner wall of the water inlet pipe 12.

[0033] In the specific implementation process, it is particularly worth noting that the function of the heat insulation layer is to play a partition role to prevent the smoke guide pipe 1 from being affected by high-temperature oil fume and transmitting it. The staff can use the water inlet pipe to supplement the water volume in the water storage tank 19. At the same time, the dust-proof net 13 can prevent dust from entering and polluting the second water pump 15 and affecting its operation.

[0034] Specifically, when using this building environmental protection flue structure, the staff starts the first servo motor 2 to drive the rotating rod 3 and the impeller 4 to rotate, so as to cool the oil fume entering the smoke inlet pipe 26. At the same time, when it meets the cold in the condensation pipe 5, it is fully liquefied under the condensation effect, and the grease will fall. Then, under the collection effect of the oil collecting cover 7, the oil fume is separated, and the grease in the oil fume falls into the oil collecting tank 6. Then, the first water pump 11 is started to make the water flow through the spray pipe 22 and form a water mist from the water spray head 23 to capture impurities such as dust and dirt, and make them fall under the influence of gravity, so that the treated gas is discharged from the smoke outlet pipe 27.

[0035] Example 2: Consisting of Figure 1 and 2It can be seen that one side of the box body 8 far from the connecting pipe 21 is connected to the input end of the first water pump 11 through a filter pipe 24, and a plurality of second filter meshes 25 are fixedly connected to the inner wall of the filter pipe 24;

[0036] In the specific implementation process, it is particularly pointed out that after the task of capturing oil molecules and dust is completed, the polluted water falls under the influence of gravity. Under the influence of the first water pump 11, the polluted water enters the filter pipe 24 for centralized treatment. Through the design of the second filter mesh 25, the polluted water collected in the filter pipe 24 can be filtered, and then flows back to the spray pipe 22 through the first water pump 11 to ensure the effect of recycling water;

[0037] Specifically, on the basis of the above-mentioned first embodiment, with the cooperation of the filter pipe 24 and the second filter screen 25, the water in the box body 8 achieves the effect of recycling water, achieving the purpose of saving water and reflecting the concept of environmental protection.
