Technical Field

[0001] This invention relates to the field of Bunsen burner technology, and more particularly to a Bunsen burner that thoroughly mixes different types of gases as an alternative fuel for aviation. Background Technology

[0002] In the study of combustion and flame characteristics, Bunsen burners are commonly used as experimental demonstration devices due to their ease of operation, simple structure, and high flame temperature, and can produce flames of different shapes. Existing Bunsen burners are generally gas-fired; fuel gas is introduced from the bottom of the burner, and air is entrained into the fuel gas through the vent. After a certain degree of mixing through the lamp neck, combustion occurs at the lamp head.

[0003] However, fuel gas cannot be fully mixed with air at low flow rates, and the instability of the mixing effect can easily cause pulsation in flame stability, thus making it impossible to obtain a stable laminar flame. Summary of the Invention

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other. The described embodiments are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention. The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Example 1

[0028] Reference Figure 1-5 As shown, the present invention provides a Bunsen burner for thoroughly mixing different types of gases, comprising:

[0029] The mixing chamber 2 has a mixing chamber inlet 9 at its bottom and a mixing chamber outlet 11 at its top. The mixing chamber 2 is equipped with a gas mixing structure.

[0030] Air intake assembly 1 includes an air passage nozzle 7, which is detachably installed at the mixing chamber inlet 9. The air passage nozzle 7 is provided with several air intake connectors, and the end of the air intake connector is connected to an air supply device.

[0031] Nozzle assembly 3 is detachably installed at the outlet 11 of the mixing chamber, and the mixed gas in the mixing chamber 2 is ejected through nozzle assembly 3.

[0032] Furthermore, the air intake connector includes a straight connector 4, an outer nut 5, and a ball connector 6. The ball connector 6 is fixedly connected to the air passage connector 7. The straight connector 4 is detachably connected to the ball connector 6 through the outer nut 5, which can maintain a good sealing environment. The end of the straight connector 4 away from the ball connector 6 is the external air passage interface.

[0033] Furthermore, sealing gaskets are provided between the nozzle assembly 3 and the mixing chamber outlet 11, and between the gas line connector 7 and the mixing chamber inlet 9. The sealing gaskets are metal sealing gaskets 8, and a sealed environment can be formed by squeezing the metal sealing gaskets 8 between the connecting surfaces.

[0034] Furthermore, the mixing chamber 2 includes several furnace bodies 10 arranged vertically, with the furnace bodies 10 stacked sequentially and adjacent furnace bodies 10 fixedly connected.

[0035] Furthermore, the top of the furnace body 10 and the top of the mixing chamber inlet 9 are provided with annular protrusions, and the bottom of the furnace body 10 and the bottom of the mixing chamber outlet 11 are provided with annular grooves, with the annular protrusions and annular grooves matching each other.

[0036] Furthermore, to ensure that the gas in the mixing chamber 2 can be fully mixed, the gas mixing structure includes several partitions 14, which are fixedly connected to the inner wall of the corresponding furnace body 10. Several eccentric holes 15 are provided on the partitions 14, and the eccentric holes 15 on the partitions 14 are all located on the same side of the partitions 14. The eccentric holes 15 on adjacent partitions 14 are staggered by 180°.

[0037] Furthermore, the partition plate 14 has four eccentric holes 15. Three of the eccentric holes 15 are arranged along the circumference, and the third eccentric hole 15 is located on the side of the three eccentric holes 15 closest to the center, and is on the same radius as the middle eccentric hole 15. The distance from the middle eccentric hole 15 to the other three eccentric holes 15 is the same. This allows the airflow passing through the eccentric holes 15 to influence each other, which helps with gas mixing.

[0038] Furthermore, the nozzle assembly 3 includes a return sleeve 12 and a burner nozzle 13. The return sleeve 12 is threadedly connected to the burner nozzle 13, and the burner nozzle 13 is threadedly connected to the mixing chamber outlet 11. The return sleeve 12 is disposed in the mixing chamber 2. Several small holes are equally spaced along the circumference on the side wall of the return sleeve 12. The mixing chamber 2 and the burner nozzle 13 are connected through the small holes and the return sleeve 12. The small holes on the return sleeve 12 can prevent the gas from flowing back when it is burning externally.

[0039] The Bunsen burner, an aviation alternative fuel that thoroughly mixes different types of gases, provided by this invention, is used as follows:

[0040] Step 1: Equipment assembly;

[0041] First, the mixing chamber 2 is assembled by welding the partition 14 to the furnace body 10. Then, the furnace bodies 10 are fixed layer by layer by welding. Before welding, the position of the eccentric holes 15 needs to be adjusted so that the eccentric holes 15 on the adjacent partitions 14 are offset by 180° to ensure that the gas is fully mixed after entering the mixing chamber 2 through the air inlet assembly 1. Next, the air inlet assembly 1 and the nozzle assembly 3 are installed on the mixing chamber inlet 9 and the mixing chamber outlet 11, respectively, to complete the equipment assembly.

[0042] Step 2: Connect the two gases to be mixed to the inlet of intake assembly 1 respectively;

[0043] Step 3: Secure the device to the experimental platform;

[0044] Step 4: Adjust the flow rates of the two gases to allow them to enter the equipment for mixing;

[0045] Step 5: Ignite the mixed gas at the outlet of nozzle assembly 3 of this device and observe the combustion phenomenon;

[0046] Step 6: After the experiment, close the valve to stop the gas from entering the equipment;

[0047] Step 7: After combustion is complete and the temperature of the equipment has dropped to room temperature, clean up the experimental site.

[0048] This invention enables thorough and uniform mixing of gases, resulting in better and more ideal experimental results. Furthermore, the air intake assembly 1 of this invention can be modified according to the type of gas to be mixed, by adding an air intake connector, thereby achieving thorough and uniform mixing of multiple gases.

[0049] Example 2

[0050] Reference Figure 6 As shown, the difference between this embodiment and embodiment one is that an arc-shaped groove 16 is provided on the inner wall of the eccentric hole 15, and the orientation of the arc-shaped groove 16 is opposite to the airflow direction; the air outlet end of the eccentric hole 15 is a constricted end, and the air outlet directions of several eccentric holes 15 on the same partition 14 intersect at the bottom of the upper partition 14.

[0051] By setting the arc groove 16, the airflow can be made to swirl in the eccentric hole 15 when it passes through the eccentric hole 15. This slows down the airflow velocity and further mixes the gas. After the gas is mixed at the annular groove, it can be pressurized again by passing through the narrowing section of the eccentric hole 15, so that the airflow can hit the baffle 14 above at a higher velocity, thereby achieving gas mixing again and ensuring that the gas is fully mixed in the mixing chamber 2.

[0052] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
