Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a fuel film combustion device. Background Technology

[0002] Patent document CN1687642A discloses a fuel film combustion device, which includes a combustion chamber, an oil pipe extending into the combustion chamber and a vertical pipe connected to an L-shaped oil groove, a horizontal pipe that can be electrically heated in the upper part of the horizontal opening on the L-shaped oil groove, microgrooves and a mesh on the outer or inner surface of the horizontal pipe, a tangential air passage in the lower part of the combustion chamber, and a flow equalization mesh outside the oil groove and the horizontal pipe.

[0003] The above-mentioned scheme utilizes capillary force and wetting force to form a rising film on the inner or outer surface of the microgroove horizontal tube, thereby accelerating the evaporation rate, ensuring thorough mixing of fuel and air, saving energy, and reducing noise. However, the air intake of the tangential air passage tends to enter from the bottom of the flow equalization net, reducing the mixing efficiency of fuel and air, easily causing incomplete combustion, resulting in fuel waste, inconvenience in saving energy, and low practicality.

[0004] Therefore, this utility model provides a fuel film combustion device. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a fuel film combustion device to solve the problems mentioned in the background section. This invention, through a fixed box, an air outlet, and a dispersion mesh, facilitates the full dispersion of air and its mixing with fuel, enabling complete combustion of the fuel and avoiding incomplete combustion that produces carbon deposits, thereby improving the practicality of the device.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a fuel film combustion device, comprising a combustion box, wherein a combustion chamber is provided inside the combustion box, and a dispersion mechanism is provided inside the combustion chamber. The dispersion mechanism includes a fixed box, an air outlet, and a dispersion screen. The fixed box is fixedly installed inside one end of the combustion chamber, and the air outlets are arranged in a matrix inside one end of the fixed box. An oil inlet pipe is fixedly provided inside one end of the dispersion screen, and an atomizing head is fixedly provided at one end of the oil inlet pipe.

[0008] Furthermore, the oil inlet pipe is L-shaped, and its bottom end is fixedly installed inside the combustion chamber.

[0009] Furthermore, the top of the oil inlet pipe and the atomizing head are both located inside the dispersing mesh, and the atomizing head is truncated cone-shaped.

[0010] Furthermore, the surface of the atomizing head is provided with atomizing holes, and an electric heating wire is fixedly installed on the outer side of the top end of the oil inlet pipe.

[0011] Furthermore, the electric heating wire is installed inside one end of the dispersing mesh cover, and the oil inlet pipe is located on one side of the fixed box.

[0012] Furthermore, a fixing rod is symmetrically fixed at the top and bottom of one end of the dispersion net cover, and the fixing rod is fixedly installed at the top and bottom of the combustion chamber.

[0013] Furthermore, an air inlet is fixedly provided at the rear end of the combustion chamber, and the inner end of the air inlet is fixedly connected to the fixed chamber.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a fuel film combustion device that can supplement air into the fixed box through the air inlet, and evenly disperse the air through the fixed box and the air outlet. At the same time, the fuel inside the fuel inlet pipe is heated by the electric heating wire, so that the fuel entering the atomizing head is atomized at a faster speed and sprayed out through the atomizing hole.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a fuel film combustion device, including a combustion box 1, a combustion chamber inside the combustion box 1, and a dispersion mechanism inside the combustion chamber. The dispersion mechanism includes a fixed box 4, an air outlet 5, and a dispersion screen 3. The fixed box 4 is fixedly installed inside one end of the combustion chamber. The air outlet 5 is arranged in a matrix inside one end of the fixed box 4. An oil inlet pipe 7 is fixedly installed inside one end of the dispersion screen 3. An atomizing head 8 is fixedly installed at one end of the oil inlet pipe 7. The fixed box 4 and the air outlet 5 facilitate the uniform dispersion of air, and the air is fully mixed with the vaporized and atomized fuel through the dispersion screen 3, so that the fuel can be fully burned, avoiding the formation of carbon deposits, thereby improving the practicality of the device.

[0022] In this embodiment, the dispersion screen 3 is fixedly installed inside the other end of the combustion chamber. The dispersion screen 3 is truncated cone-shaped, and the fuel inlet pipe 7 is L-shaped. The bottom end of the fuel inlet pipe 7 is fixedly installed inside the combustion chamber 1. The top end of the fuel inlet pipe 7 and the atomizing head 8 are both installed inside the dispersion screen 3. The atomizing head 8 is truncated cone-shaped, and atomizing holes 9 are opened on the surface of the atomizing head 8. An electric heating wire 10 is fixedly installed on the outer side of the top end of the fuel inlet pipe 7. The electric heating wire 10 is installed through the inside of one end of the dispersion screen 3. The fuel inlet pipe 7 is located on one side of the fixed box 4. The electric heating wire 10 can heat the fuel inside the fuel inlet pipe 7, causing the fuel to vaporize and increase the pressure. After entering the atomizing head 8, it can be quickly discharged from the atomizing holes 9 and rapidly diffused, which facilitates the full mixing and contact of the vaporized and atomized fuel with the air, facilitating subsequent fuel combustion.

[0023] In this embodiment, a fixing rod 6 is symmetrically fixed at the top and bottom of one end of the dispersion net cover 3. The fixing rod 6 is fixedly installed at the top and bottom of the combustion chamber. The fixing rod 6 can be used to position and fix one end of the dispersion net cover 3, thereby improving the stability of the dispersion net cover 3.

[0024] In this embodiment, an air inlet 2 is fixedly provided at the rear end of the combustion chamber 1. The inner end of the air inlet 2 is fixedly connected to the fixed chamber 4. The air inlet 2 facilitates the replenishment of air into the interior of the fixed chamber 4, which facilitates the uniform dispersion of air in the future.

[0025] When using this fuel film combustion device, air is introduced into the fixed box 4 through the air inlet 2. The air inside the fixed box 4 is discharged through the air outlet 5 under air pressure, which facilitates the uniform dispersion of the air. The dispersed air continues to flow inside the combustion chamber and moves closer to the dispersion screen 3. Fuel is introduced into the fuel inlet pipe 7 through the low-pressure fuel pump, and the electric heating wire 10 is energized to heat the fuel inside the fuel inlet pipe 7. This causes the fuel to vaporize and the pressure to increase. After the vaporized fuel enters the atomizing head 8, it expands rapidly and is sprayed out from the atomizing hole 9, spreading to the outside of the atomizing head 8. This allows the air to fully contact and mix with the vaporized fuel, facilitating complete combustion of the fuel and avoiding incomplete combustion that produces carbon deposits. This improves the practicality of the device and helps save energy.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
