Definitions
- the present invention is related to a burner and, more particularly, to a smoke removal device, which is used to efficiently burn the particulates in the smoke.
- Conventional combustion devices e.g., furnaces, gold furnaces, or coffee bean roasters
- the thermal energy provided by the combustion device changes the density of the air, thereby generating a gas flow and forming the smoke full of the particulates.
- the particulates are discharged outside the combustion device with the smoke and dispersed in the air.
- the smoke full of the particulates and dispersed in the air would pollute the environment.
- the particulates with small volume and light mass are moved by the gas flow easily, result in increasing the possibility of the particulates being inhaled.
- the particulates When being inhaled by the creature and getting into the respiratory tract of the creature, the particulates would stimulate the respiratory tract and could cause the creature to be uncomfortable, like being allergic or suffering from asthma.
- Some particulates would even attach to the lung and could not be discharged which causes the creature to suffer from a more serious disease, such as bronchitis or pneumonia.
- some smoke not only contains the particulates but also contains toxic metal carcinogen that would make the body feel ill and even worse have a risk of getting cancer.
- a known solution to deal with the problems above is installing a filter element or a filter net on the smoke discharge route of the burner to filter the particulates in the smoke.
- the filter element or the filter net needs to be regularly replaced to ensure its filtering quality for the particulates.
- it costs high to use the filter element or the filter net to filter the particulates and it is not an easy work to replace the filter element or the filter net regularly.

Abstract
Description
- The present invention is related to a burner and, more particularly, to a smoke removal device, which is used to efficiently burn the particulates in the smoke.
- Conventional combustion devices (e.g., furnaces, gold furnaces, or coffee bean roasters) generate particulates during combustion of the material, and the thermal energy provided by the combustion device changes the density of the air, thereby generating a gas flow and forming the smoke full of the particulates. Finally, the particulates are discharged outside the combustion device with the smoke and dispersed in the air.
- The smoke full of the particulates and dispersed in the air would pollute the environment. The particulates with small volume and light mass are moved by the gas flow easily, result in increasing the possibility of the particulates being inhaled. When being inhaled by the creature and getting into the respiratory tract of the creature, the particulates would stimulate the respiratory tract and could cause the creature to be uncomfortable, like being allergic or suffering from asthma. Some particulates would even attach to the lung and could not be discharged which causes the creature to suffer from a more serious disease, such as bronchitis or pneumonia. Furthermore, some smoke not only contains the particulates but also contains toxic metal carcinogen that would make the body feel ill and even worse have a risk of getting cancer.
- A known solution to deal with the problems above is installing a filter element or a filter net on the smoke discharge route of the burner to filter the particulates in the smoke. However, the filter element or the filter net needs to be regularly replaced to ensure its filtering quality for the particulates. However, it costs high to use the filter element or the filter net to filter the particulates and it is not an easy work to replace the filter element or the filter net regularly. Especially, the bigger the burner is, the more obvious the disadvantage of using these kinds of filter would be, so the use of the filter element or the filter net is not a practical way to deal with the problems mentioned above.
- In view of the above, the purpose of the present invention is to provide a smoke removal device which can effectively burn off the particulates in the smoke.
- The present invention provides a smoke removal device including a tube body and a combustion unit. The tube body includes a first end and a second end opposite to the first end. The combustion unit includes a main body, a gas pipeline, and a lighter. The main body is located at the first end of the tube body. A smoke passage is formed between a periphery of the main body and an inner wall of the tube body. The smoke gets into the smoke removal device through the smoke passage. The main body has a central passage communicating with the smoke passage. A fuel gas is guided into the central passage by the gas pipeline and then is ignited by the lighter located in the central passage to generate a fire. The fire then burns the particulates in the smoke passing through the smoke passage.
- The advantage of the present invention is that efficiently facilitates the particulates passing through the smoke passage to be burned by the fire produced by the burner, and decreases the possibility that the fuel gas released from the gas pipeline is interfered by the air flow formed by the particulates passing through.

FIG. 1 to FIG. 4 show thesmoke removal device 100 of the first embodiment. - The
smoke removal device 100 includes a base10, acylinder 12, atube body 14, aconverging tube 16, a guidingfan 18, and a combustion unit. Thebase 10 being a hollow structure has afixing portion 10a and anaccommodating room 10b. Thefixing portion 10a is located in thecylinder 12. Thecylinder 12 is mounted on thebase 10 and has a plurality ofheat dissipation openings 12a. A first end of thetube body 14 is connected to thefixing portion 10a of thebase 10, while a second end of thetube body 14 is connected to theconverging tube 16, thereby thebase 10, thetube body 14 and theconverging tube 16 all communicating to each other. The guidingfan 18 is provided in theaccommodating room 10b of thebase 10 and surrounds the combustion unit. - The combustion unit includes a
main body 20, agas pipeline 22, a lighter 24, and a Venturitube 26. Themain body 20 is located at the first end of thetube body 14 and is disposed in theaccommodating room 10b. A smoke passage C is formed between a periphery of themain body 20 and an inner wall of thetube body 14 as well as between the periphery of themain body 20 and an inner wall of thebase 10. - Referring to
FIG. 3 , themain body 20 has a central passage G going through themain body 20 from a bottom surface to a top surface and being conical in shape. An end of thegas pipeline 22 is connected to a fuel gas supplier (not shown), while the other end of thegas pipeline 22 is provided with aconnecting tube 23. The connectingtube 23 passes through the bottom surface of themain body 20, extends into the central passage G, forms a gas outlet in the central passage G, and is connected to anozzle 22a through the gas outlet. Therefore, the fuel gas could be guided by thegas pipeline 22, the connectingtube 23, and then thenozzle 22a to flow into the central passage G. - The lighter 24 is provided in the central passage G and has a heating end above the gas outlet of the
gas pipeline 22 for igniting the fuel gas in the central passage G. In the present embodiment, the lighter 24 has aseat 24a and anelectric fire bar 24b as the heating end mentioned above. The electricity is delivered from theseat 24a to theelectric fire bar 24b which converts the electricity into the heat energy. Theelectric fire bar 24b in high temperature is adapted to ignite the fuel gas in the central passage G to generate the fire, and then the fire burns the smoke passing through the smoke passage C. In practice, the lighter 24 could ignite the fuel gas in other manners (for example, using the spark generated by a high-voltage power supply). - The Venturi
tube 26 is located in the central passage G of themain body 20. An end of the Venturitube 26 is connected to a top portion of themain body 20 through acover 26a and faces the tube body, while the other end of the Venturitube 26 extends toward but is above the gas outlet of the gas pipeline at the bottom of themain body 20. The Venturitube 26 has a tapering portion where the Venturitube 26 has the smallest diameter. When the fuel gas gets into the Venturitube 26 and passes through the tapering portion, the flowing rate of the fuel gas would increase. In an embodiment, the Venturitube 26, thecover 26a, and themain body 20 could be integrally formed as a monolithic unit. The central passage G communicates with thetube body 14 through the Venturitube 26. - The
main body 20 has alateral opening 20a on its side wall, though the number of thelateral opening 20a is not limited as above and could be two or more. Thelateral opening 20a is located above the gas outlet, faces a wall of the Venturitube 26, and is adapted for the outer air getting into the central passage G. If the air in themain body 20 is not enough for combustion, a blower (not shown) located outside thesmoke removal device 100 could be connected to thelateral opening 20a through a connectingpipe 28, to efficiently supply the air. After entering themain body 20, the air would flow around an outer wall of the Venturitube 26. When flowing to the end of the Venturitube 26 close to the bottom of themain body 20, the air would enter the Venturitube 26 with the fuel gas. Referring toFIG. 3 , the arrow F shows the direction of the air flow. - The guiding
fan 18 forces the smoke to flow upward around a reference axis L when the smoke gets into the tube body 14 (as shown inFIG. 4 ), which increases the chance of the smoke to be burned by the fire produced by the combustion unit, thereby decreasing the amount of the residual particulates in the smoke to reduce the pollution caused to the environment. - All in all, with the aforementioned design of the combustion unit, the particulates in the smoke could be totally burned by the fire produced by the combustion unit, when passing through the smoke passage C. It is also worth mentioning that by the arrangement of the
main body 20, thegas pipeline 22 and the lighter 24 in the combustion unit, the fuel gas would not be interfered by the smoke passing through the smoke passage C when leaving the gas outlet. A chance that the concentration of the fuel gas would be decreased due to being interfered by the smoke could be ruled out. The lighter 24 would fail to ignite the fuel gas if the concentration of the fuel gas is too low. A space between thecylinder 12 and thetube body 14 is adapted to prevent thecylinder 12 from raising temperature quickly due to the heat released from thetube body 14, so that a user would not suffer scald when touching thecylinder 12. -
FIG. 5 andFIG. 6 show thesmoke removal device 100A according to a second embodiment. The structure and the function of thebase 10, thecylinder 12, thetube body 14, the convergingtube 16, the guidingfan 18, and the combustion unit of thesmoke removal device 100A in the second embodiment are the same as that in the first embodiment, so they would not be described again thereafter. It is worth to be mentioned that thesmoke removal device 100A of the second embodiment further includes aheat insulation layer 30, an extendingtube 32, a shieldingplate 34, and asupport frame 36. - The
heat insulation layer 30 is located between thetube body 14 and thecylinder 12 to prevent the transfer of heat from where theheat insulation layer 30 faces thetube body 14, which makes the temperature of thecylinder 12 not increase easily. In practice, theheat insulation layer 30 could be a layer or a film made of ceramic material or polymeric material. The diameter of the extendingtube 32 is less than that of thetube body 14, and the extendingtube 32 is disposed on themain body 20 of the combustion unit. An end of thesupport frame 36 is connected to the extendingtube 32, while the other end of thesupport frame 36 is connected to the shieldingplate 34. - In the present embodiment, the
support frame 36 is adjustable in length, though, in practice, it could be designed in a constant length. Furthermore, the extendingtube 32 and the shieldingplate 34 both have a plurality offlame openings FIG. 6 ). The diameter of the shieldingplate 34 is less than the inner diameter of thetube body 14, but is more than or is equal to three quarters of the inner diameter of thetube body 14. The shieldingplate 34 is adapted to keep most of the fire below it, and most of the smoke could be burned here. - With the design of the extending
tube 32, the shieldingplate 34 and thesupport frame 36 of the present embodiment, the fire produced by the combustion unit could concentrate to a central axis of thetube body 14 instead of deviating due to being interfered by the flowing smoke. After going up, the fire would be blocked by the shieldingplate 34, and then form a fire wall along the shieldingplate 34 within thetube body 14. A gas flow rises when it receives the heat from the fire, which causes pressure difference in the extendingtube 32 and forces the outer smoke to flow into the extendingtube 32 and be burned by the fire. The smoke which is still between the extendingtube 32 and thetube body 14 could also be burned by the fire which goes out through theflame openings 32a of the extendingtube 32 or goes out through thesupport frame 36. The smoke that goes up with the rising gas flow could be burned by the fire wall, theheating shielding plate 34, or the fire going out through theflame openings 34a in the shieldingplate 34. - In practice, a user could choose whichever the extending
tube 32, the shieldingplate 34, and thesupport frame 36 to assemble and dispose, such the selectivity depending on his need. Besides the aspect of the second embodiment, the user could dispose only the extendingtube 32 on themain body 20 without the other two, or dispose the extendingtube 32 on themain body 20 through thesupport frame 36 without the extendingtube 32. -
FIG. 7 andFIG. 8 show thesmoke removal device 100B according to a third embodiment. Most of the components and the structure of thesmoke removal device 100B in the present embodiment are similar to that of the second embodiment so they would not be mentioned again hereafter. It is to be noted that the present embodiment discloses thesmoke removal device 100B without the guidingfan 18, the connectingpipe 28, and the extendingtube 32, so the air for combustion comes from the smoke passage C. The air gets into themain body 20 through thelateral opening 20a and flows as the arrow F shows, which has described above. - In the present embodiment, the shielding
plate 34 is supported above themain body 20 through thesupport frame 36, and thesupport frame 36 is directly disposed on themain body 20. Thesmoke removal device 100B further includes aheat storage mesh 38 and aflame shield 40. Theheat storage mesh 38 is a metal mesh, for example a ferrite-chromium-aluminum mesh supported by thesupport frame 36 through an outer periphery of theheat storage mesh 38 between themain body 20 and the shieldingplate 34 and corresponds to the central passage G. Theflame shield 40 is disposed at a side of theheat storage mesh 38 near the shieldingplate 34 and is fixed through a bolt and anut 42. - The shielding
plate 34 could slow down the flow rate of the smoke entering thesmoke removal device 100B, which elongates the time of the smoke staying within thesmoke removal device 100B. Theheat storage mesh 38 is heated by the fire, and the particulates in the smoke are burned by theheat storage mesh 38 then. The fire is guided by theflame shield 40 to spread toward the peripheral of theheat storage mesh 38, which makes more surface area of theheat storage mesh 38 be in contact with the fire. Such design permits the particulates in the smoke to be totally burned. In an embodiment, thesmoke removal device 100B may not use theflame shield 40. - Moreover, in the present embodiment, the
nozzle 22a is awindproof nozzle 44 having anentrance 44a, and anexit 44b. Theentrance 44a is connected to the connectingtube 23, and theexit 44b faces theVenturi tube 26. There is provided a gas outlet I between theentrance 44a and theexit 44b in thewindproof nozzle 44, and the inner diameter of theexit 44b is greater than that of theentrance 44a, so that the fuel gas would not be dispersed by the air flow.
