Description

Technical Field

[0001] This utility model belongs to the field of furnace head combustion technology, specifically relating to a vaporization combustion furnace head. Background Technology

[0002] In traditional gasification burners, the part that vaporizes liquid fuel is a single annular structure, which allows for continuous vaporization through the heat of combustion after combustion begins. However, in actual operation, some liquid fuel cannot be fully vaporized, resulting in unsatisfactory combustion performance.

[0003] In addition, traditional vaporization burners are all molded in one piece, which has a high processing cost and is difficult to inspect and maintain. Considering that there may be high pressure in the vaporization part, the thickness of the burner head is increased as much as possible to provide sufficient safety strength.

[0004] Based on this, this utility model has conducted in-depth research on traditional burners in order to design a vaporization combustion burner that can solve the above problems, ensure full vaporization, and reduce equipment costs. Utility Model Content

[0005] To overcome the above problems, the inventors conducted in-depth research and designed a vaporization combustion burner head. This burner head is divided into upper and lower parts, which can be made of different materials. Each part is provided with a vaporization chamber. The two vaporization chambers are connected by an external elbow pipe. By setting two vaporization chambers, the liquid fuel is fully vaporized, improving the combustion quality. A liquid fuel connector, a gas nozzle, an ignition needle, a safety needle, and an electrode are set on the lower end head. A steel sleeve is installed in the combustion space to protect the upper connector and seal the gap between the upper connector and the lower end head, improving the overall user experience of the burner head, thus completing this utility model.

[0006] Specifically, the purpose of this utility model is to provide a vaporization combustion burner head, which includes an upper connector 1 and a lower end 2. A cylindrical upper combustion chamber 31 is provided on the upper connector 1, and a cylindrical lower combustion chamber 32 is provided on the lower end 2. A liquid fuel connector 21 is provided on the lower end 2, outside the lower combustion chamber 32.

[0007] A primary vaporization chamber 22, which is arranged in a ring shape and surrounds the outside of the lower combustion chamber 32, is provided in the lower end 2.

[0008] A secondary vaporization chamber 11, which is annular and surrounds the outer side of the upper combustion chamber 31, is provided in the upper connector 1.

[0009] The liquid fuel connector 21 is connected to the primary vaporization chamber 22, and the primary vaporization chamber 22 is connected to the secondary vaporization chamber 11.

[0010] A gas nozzle 4 is also provided on the lower end 2. The gas nozzle 4 is connected to the secondary vaporization chamber 11 and extends into the combustion space formed by the upper combustion chamber 31 and the lower combustion chamber 32.

[0011] Liquid fuel enters the vaporization combustion head through liquid fuel connector 21, vaporizes after passing through primary vaporization chamber 22 and secondary vaporization chamber 11, mixes with outside air in gas nozzle 4 and is then discharged into the combustion space for combustion.

[0012] A primary outlet pipe 23 is provided at the bottom of the primary vaporization chamber 22.

[0013] A secondary inlet pipe 12 and a secondary outlet pipe 13 are provided at the bottom of the secondary vaporization chamber 11;

[0014] The primary outlet pipe 23 is connected to the secondary inlet pipe 12 via the first elbow connector 51, and the secondary outlet pipe 13 is connected to the gas nozzle 4 via the second elbow connector 52.

[0015] Two through holes 24 are provided on the lower end 2. The secondary inlet pipe 12 and the secondary outlet pipe 13 pass through the through holes 24 independently, thereby fixing the upper connector 1 and the lower end 2 into one unit, so that the first elbow connector 51 and the second elbow connector 52 are both located at the bottom of the lower end 2.

[0016] Inside the lower end head 2, a base plate 25 is provided at the bottom of the lower combustion chamber 32. The upper end of the gas nozzle 4 passes through the base plate 25 and is located in the combustion space. The lower end of the gas nozzle 4 is located below the base plate 25. An air inlet 41 is provided on the side of the lower end of the gas nozzle 4, and air is drawn in through the air inlet 41.

[0017] In the lower combustion chamber 32, a pressure cap 6 is provided on the gas nozzle 4, and the pressure cap 6 blocks the gas nozzle 4 in the vertical direction;

[0018] The side of the pressure cap 6 is densely provided with air outlets 61, through which mixed gas is injected into the combustion space.

[0019] The burner head also includes an ignition needle 71 and a safety needle 72, which extend into the combustion space after passing through the bottom plate 25 from the bottom.

[0020] Among them, on the lower end 2, a positive electrode 81 and a negative electrode 82 are provided on the outside of the lower combustion chamber 32, and the positive electrode 81 and the negative electrode 82 are adjacent to the first-stage vaporization chamber 22.

[0021] When the vaporization combustion furnace head starts working, the liquid fuel in the primary vaporization chamber 22 is heated by discharge through the positive electrode 81 and the negative electrode 82, causing it to vaporize.

[0022] An annular baffle 14 is provided at the edge of the upper connector 1, and the lower end 2 is embedded into the inner side of the baffle 14 and closely adheres to the baffle.

[0023] A steel sleeve 9 is provided inside the upper combustion chamber 31 and the lower combustion chamber 32. The steel sleeve 9 is close to the inner wall of the upper connector 1 and the lower end 2, and the bottom of the steel sleeve 9 abuts against the base plate 25.

Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0065] This utility model provides a vaporization combustion burner head, such as Figure 1 , Figure 2 and Figure 3 As shown, the burner head includes an upper connector 1 and a lower end 2, which can be separated from each other and can be made of different materials.

[0068] A secondary vaporization chamber 11 is provided in the upper connector 1 in an annular shape surrounding the outer side of the upper combustion chamber 31; the vaporization chamber is arranged around the combustion chamber so that when the combustion chamber is continuously burning, the heat generated by the combustion causes the liquid fuel in the vaporization chamber to vaporize.

[0069] The liquid fuel connector 21 is connected to the primary vaporization chamber 22, and the primary vaporization chamber 22 is connected to the secondary vaporization chamber 11.

[0070] A gas nozzle 4 is also provided on the lower end 2. The gas nozzle 4 is connected to the secondary vaporization chamber 11 and extends into the combustion space formed by the upper combustion chamber 31 and the lower combustion chamber 32.

[0071] Liquid fuel enters the vaporization combustion head through liquid fuel connector 21, vaporizes after passing through primary vaporization chamber 22 and secondary vaporization chamber 11, mixes with outside air in gas nozzle 4 and is then discharged into the combustion space for combustion.

[0072] In a preferred embodiment, such as Figure 2 As shown, a primary outlet pipe 23 is provided at the bottom of the primary vaporization chamber 22.

[0073] A secondary inlet pipe 12 and a secondary outlet pipe 13 are provided at the bottom of the secondary vaporization chamber 11;

[0075] In a preferred embodiment, such as Figure 7 , Figure 8 and Figure 9 As shown, two through holes 24 are opened on the lower end 2. The secondary inlet pipe 12 and the secondary outlet pipe 13 pass through the through holes 24 independently, thereby fixing the upper connector 1 and the lower end 2 into one piece, so that the first elbow connector 51 and the second elbow connector 52 are both located at the bottom of the lower end 2.

[0076] Preferably, inside the lower end head 2, a base plate 25 is provided at the bottom of the lower combustion chamber 32, the upper end of the gas nozzle 4 passes through the base plate 25 and is located in the combustion space, and the lower end of the gas nozzle 4 is located below the base plate 25; an air inlet 41 is provided on the side of the lower end of the gas nozzle 4, and air is drawn in through the air inlet 41.

[0077] Preferably, such as Figure 10 As shown in the figure, in the lower combustion chamber 32, a pressure cap 6 is provided on the gas nozzle 4, and the pressure cap 6 blocks the gas nozzle 4 in the vertical direction;

[0079] Preferably, the burner head further includes an ignition needle 71 and a safety needle 72, which extend into the combustion space after passing through the bottom plate 25 from the bottom. The ignition needle is used to ignite the combustion-state gas in the combustion chamber, and the safety needle is used to detect the combustion state and ensure that the gas input is shut off after combustion is completed.

[0081] When the vaporization combustion furnace head is started, the liquid fuel in the first-stage vaporization chamber 22 is heated by discharge through the positive electrode 81 and the negative electrode 82, so that it is vaporized; after the ignition in the combustion space is completed, the combustion space can continuously provide heat, and the liquid fuel can be vaporized without the electrodes being energized. At this time, the positive electrode 81 and the negative electrode 82 can be stopped working.

[0082] Preferably, an annular baffle 14 is provided at the edge of the upper connector 1, and the lower end 2 is embedded into the inner side of the baffle 14 and closely attached to the baffle. This structural design makes the overall structure of the combustion burner head beautiful and complete, and it is not easy to be scratched or scraped during installation and use.

Based on this, various substitutions and improvements can be made to the present invention, all of which fall within the protection scope of the present invention.
