Description

Technical Field

[0001] The present invention relates to a burner head, specifically a secondary vaporization burner head, belonging to the technical field of vaporization burner heads. Background Art

[0002] A vaporization burner head, also known as a gasification burner head, is an important part of a vaporization furnace, responsible for converting fuel from a liquid state to a gaseous state and guiding its efficient combustion. According to different fuel types and design structures, vaporization burner heads can be divided into various types, such as alcohol-based gasification burner heads, diesel gasoline alcohol combined burner heads, etc. As an important part of the vaporization furnace, the vaporization burner head plays an important role in the efficient combustion of fuel and energy conservation and environmental protection. With the continuous progress of technology and the continuous expansion of application fields, the performance of the vaporization burner head will be continuously improved, bringing more convenience and benefits to people's production and life.

[0003] The working principle of the vaporization burner head mainly involves the vaporization and combustion processes of fuel. The fuel first enters the nozzle from the fuel pipe for heating. When the temperature reaches 65 °C, the alcohol-based fuel begins to change from a liquid to a gas, and then the gas flows back to the combustion chamber and is ignited by an open flame. The blower at the bottom of the burner head continuously blows air into the combustion chamber, sending oxygen-rich air into the combustion chamber, so that the fuel burns fully in the burner head.

[0004] When a traditional vaporization furnace is in use, the fuel vaporizes insufficiently, which in turn leads to incomplete combustion of the fuel and a low combustion efficiency. In the prior art, to solve this problem, a secondary vaporization method is often used to improve the vaporization efficiency of the fuel, so that the fuel burns fully;

[0005] For example, the Chinese publicly authorized patent (Publication No.: CN220648241U) discloses a vaporization burner head for light fuel oil. It introduces crude oil into the first heating chamber through the first fuel pipe for heating to vaporize the oil for the first time. Then the vapor-oil mixture flows into the connecting pipe connected to the first heating chamber and then into the second vaporization chamber for secondary vaporization. The fully vaporized gaseous oil enters the upper end of the second vaporization chamber and is ejected. At the same time, the igniter ignites the top of the fuel injector to burn the gaseous oil. Finally, the flame of the burning gaseous oil sprays upward through the fire cap. After multiple treatments of the crude oil, it can burn fully;

[0006] It adds a secondary vaporization step for the fuel crude oil, enabling the fuel crude oil to be fully vaporized and burned. However, its technical solution still has the following technical problems:

[0007] It transports and vaporizes the fuel crude oil through the fuel pipe, but does not set up an oil quantity adjustment mechanism, so it is inconvenient to adjust the size of the combustion firepower. Moreover, the second vaporization chamber is equipped with a rod-shaped heater, and when secondary vaporization occurs, the heating area of the fuel pipe is small, so there will be a situation where the vaporization efficiency of the fuel crude oil is low. Therefore, a secondary vaporization burner head is proposed. Summary of the Invention

Detailed implementation manners

[0038] In the following, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present invention. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0039] The following will describe the embodiments of the present invention in detail with reference to the drawings.

[0040] As Figure 1-8 shown in the figure, an embodiment of the present invention provides a secondary vaporization type burner head, which includes a vaporization assembly 101. The vaporization assembly 101 includes a first oil pipe 11, an oil pipe joint 12, a throttle valve 13, a secondary vaporization heating pipe 14, a secondary vaporization chamber 15, a second oil pipe 16, an injection nozzle joint 18, and a vaporization injection nozzle 19;

[0041] The oil pipe joint 12 is installed at one end of the first oil pipe 11. The other end of the first oil pipe 11 is communicated with the inlet end of the throttle valve 13. One end of the second oil pipe 16 is communicated with the outlet end of the throttle valve 13. The bottom end of the injection nozzle joint 18 is communicated with the other end of the second oil pipe 16. The vaporization injection nozzle 19 is installed at the top end of the injection nozzle joint 18. The secondary vaporization heating pipe 14 is installed inside the secondary vaporization chamber 15. The secondary vaporization heating pipe 14 is continuously bent in an S shape. The second oil pipe 16 is wound around the outside of the secondary vaporization heating pipe 14. An oil pipe spacer 40 is installed on the outer side wall of the first oil pipe 11. By setting the secondary vaporization heating pipe 14 into a continuously bent S shape, the heat receiving area of the second oil pipe 16 can be increased, so that the fuel crude oil in the second oil pipe 16 is fully vaporized, so as to achieve the purpose of improving the combustion efficiency. Through the oil pipe spacer 40, it can be ensured that the first oil pipe 11 does not deform during heating and the first oil pipe 11 is uniformly heated under the action of the heating pipe.

[0042] In one embodiment, the second oil pipe 16 is located inside the secondary vaporization chamber 15. The injection nozzle joint 18 is installed on the upper surface of the secondary vaporization chamber 15. The fuel crude oil can be input into the first oil pipe 11 through the oil pipe joint 12. Then the fuel oil in the first oil pipe 11 flows into the throttle valve 13, the second oil pipe 16, and the injection nozzle joint 18 in sequence, and finally is sprayed out through the vaporization injection nozzle 19. At this time, the fuel oil is completely vaporized and can be fully burned;

[0043] During the transportation process of the fuel crude oil, the throttle valve 13 can play a role in adjusting the combustion firepower. The first oil pipe 11 and the second oil pipe 16 are connected by the throttle valve 13. By rotating the throttle valve 13, the cross-sectional area of the internal channel of the throttle valve 13 is changed, so that the flow rate of the fuel crude oil can be adjusted. When the flow rate of the fuel crude oil decreases, the combustion firepower decreases. When the flow rate of the fuel crude oil increases, the combustion firepower increases. By adjusting the flow rate of the fuel crude oil, the combustion firepower can be quickly and accurately adjusted.

[0044] In one embodiment, the vaporization assembly 101 further includes a secondary vaporization thermocouple 17, a primary vaporization thermocouple 20, a primary vaporization heating pipe 21, and a power line 22;

[0045] The electrical input terminals of the secondary vaporization thermocouple 17, the electrical input terminals of the primary vaporization heating tube 21, and the electrical input terminals of the primary vaporization thermocouple 20 are all electrically connected to the electrical output terminal of the power supply line 22. The electrical input terminal of the power supply line 22 is connected to the electrical output terminal of an external power supply to supply power to the secondary vaporization thermocouple 17 and the primary vaporization thermocouple 20.

[0046] The primary vaporization heating tube 21 is located between the first oil pipes 11, so that the first vaporization can be more uniform and rapid.

[0047] The secondary vaporization thermocouple 17 is installed inside the secondary vaporization chamber 15. The primary vaporization heating tube 21 is annular and located outside the first oil pipes 11. The first oil pipes 11 can be heated by the primary vaporization heating tube 21 to vaporize the fuel crude oil inside the first oil pipes 11.

[0048] The vaporization temperature inside the secondary vaporization chamber 15 can be monitored by the secondary vaporization thermocouple 17, and the vaporization temperature of the first oil pipes 11 can be monitored by the primary vaporization thermocouple 20, thereby improving the overall safety. The signal output terminals of the secondary vaporization thermocouple 17 and the primary vaporization thermocouple 20 are both connected to the signal receiving terminal of an external control terminal.

[0049] In one embodiment, a main body assembly 301 is installed outside the first oil pipes 11. The main body assembly 301 includes a furnace body 31, a fire cap 32, a fire tube 34, a mounting seat 35, and a connecting plate 36.

[0050] The fire cap 32 is installed on the upper surface of the furnace body 31. The connecting plate 36 is fixedly connected to the upper surface of the fire tube 34. The connecting plate 36 is fixedly connected to the lower surface of the furnace body 31 by bolts. The mounting seat 35 is installed on the lower surface of the fire tube 34. Air holes 38 are evenly formed in the outer side wall of the fire tube 34. Sufficient oxygen can be ensured inside the fire tube 34 through the air holes 38, so as to realize the full combustion of the fuel crude oil.

[0051] In one embodiment, both the first oil pipes 11 and the primary vaporization heating tube 21 are embedded inside the furnace body 31. The first oil pipes 11 are spiral. The primary vaporization thermocouple 20 is installed on the lower surface of the furnace body 31, and the top end of the primary vaporization thermocouple 20 is located inside the furnace body 31. The fuel crude oil inside the first oil pipes 11 can be preliminarily vaporized by the primary vaporization heating tube 21. By setting the first oil pipes 11 to be spiral, the heating area of the first oil pipes 11 can be increased.

[0052] In one embodiment, the main body assembly 301 further includes an ignition needle 37 and a fixing seat 39.

[0053] Both ignition needles 37 are installed on the upper surface of the fixed seat 39. The fixed seat 39 is fixedly connected to the mounting seat 35 by bolts. The fuel injector joint 18 is installed inside the furnace barrel 34. The ignition needles 37 are located inside the furnace barrel 34. The positions of the ignition needles 37 correspond to the positions of the vaporizing fuel injectors 19. After the fuel crude oil is vaporized twice, the pressure in the second oil pipe 16 increases. Then, the vaporized fuel oil is ejected from the top of the vaporizing fuel injector 19. After being ignited by the ignition needles 37, the gaseous fuel oil can be ignited to burn fully, and the combustion flame sprays upward from the fire cap 32.

[0054] When the present invention is in operation: The fuel crude oil is input into the first oil pipe 11 through the oil pipe joint 12. The fuel oil in the first oil pipe 11 is vaporized by the primary vaporizing heating pipe 21 inside the furnace body 31. The preliminarily vaporized fuel oil flows into the second oil pipe 16 through the throttle valve 13. The fuel oil in the second oil pipe 16 is vaporized twice by the secondary vaporizing heating pipe 14. Since the secondary vaporizing heating pipe 14 is bent into a continuous S shape, the heating area of the second oil pipe 16 can be increased, so that the fuel crude oil in the second oil pipe 16 is fully vaporized. The fully vaporized fuel oil is ejected from the top of the vaporizing fuel injector 19. The gaseous fuel oil can be ignited by the ignition needles 37, so that the fuel oil burns fully, and the combustion flame sprays upward from the fire cap 32.

[0055] During the vaporization and combustion process of the fuel crude oil, by rotating the throttle valve 13, the cross-sectional area of the internal channel of the throttle valve 13 can be changed, thereby adjusting the flow rate of the fuel crude oil. When the flow rate of the fuel crude oil decreases, the combustion firepower decreases; when the flow rate of the fuel crude oil increases, the combustion firepower increases, realizing the rapid and precise adjustment of the combustion firepower.

[0056] The vaporization temperature in the secondary vaporization chamber 15 can be monitored by the secondary vaporization thermocouple 17, and the vaporization temperature of the first oil pipe 11 can be monitored by the primary vaporization thermocouple 20, thereby improving the overall safety.

[0057] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
