Description

Technical Field

[0001] This application relates to the technical field of oil burners, and specifically to a high-efficiency and clean biomass oil burner. Background Technique

[0002] During road construction, a burner is needed to heat the kettle to boil asphalt. In order to reduce the use cost of the burner, in the prior art, biomass oil waste is mostly used as fuel. Since biomass oil waste is mostly composed of waste engine oil, animal and vegetable oil, etc., its viscosity is relatively large. Therefore, before use, the waste oil needs to be heated first. After heating it to 80-100°C, wait for its viscosity to decrease before it can be sprayed out from the spray pipe for use in the combustion chamber. However, during the heating process of biomass oil waste, the volatile substances contained in it will volatilize into the air, causing environmental pollution.

[0003] To avoid environmental pollution, in the prior art, a cold oil spray gun is mostly used to supply oil to the burner. However, the oil sprayed by the cold oil spray gun cannot be in full contact with the air, which leads to incomplete combustion of the oil and generates a large amount of black smoke, resulting in air pollution. At the same time, most of the igniters of the current burners use electrode needles for ignition. However, the flash point of biomass oil is relatively high, and the success rate of ignition using an ignition needle is not high. Summary of the Invention

[0004] This application provides a high-efficiency and clean biomass oil burner. The pressurized biomass oil is sprayed out from multiple atomizing nozzles, so that the biomass oil can be in full contact with the air, effectively improving the combustion efficiency of the biomass oil and realizing the high-efficiency and clean combustion of the biomass oil. Ignition is carried out through a dedicated gas igniter, effectively improving the ignition success rate, and can effectively solve the problems in the background technique.

[0005] To achieve the above object, this application provides the following technical solution: A high-efficiency and clean biomass oil burner, including a box body; a fuel supply system and an ignition system are installed inside the box body. The box body is connected to a cylindrical barrel through a support barrel provided on its upper surface. A air supply mechanism is installed inside the cylindrical barrel.

A flow diffuser is installed on the right side of the partition.

[0006] The ignition system includes a liquefied gas cylinder provided inside the box body and an igniter installed in the middle of the right side of the partition. A solenoid valve is installed at the air outlet of the liquefied gas cylinder. The liquefied gas cylinder is connected to the igniter through a conduit.

[0007] Preferably, a mounting seat is installed at the lower end of the outer side of the box body.

[0008] Preferably, the fuel supply system includes a fuel tank and a fuel pump installed inside the box body. The liquid inlet of the fuel pump is connected to the fuel tank through a conduit.

[0009] Preferably, a fuel filling nozzle is provided on the fuel tank.

[0010] Preferably, an openable sealed door is provided on the front side of the box body.

[0011] Preferably, the igniter includes an outer shell body, on which an air jet hole and a pulse igniter are provided. The air jet hole is connected to a liquefied gas cylinder through a conduit.

[0012] Preferably, the air supply mechanism includes a blower installed at the left end of the inner side of the cylindrical barrel.

[0015] 1. For this biomass oil high-efficiency and clean burner, the pressurized biomass oil is ejected from multiple atomizing nozzles, so that the biomass oil can be in full contact with air, effectively improving the combustion efficiency of the biomass oil.

A flow diffuser nozzle 5 is installed on the right side of the partition board 12.

[0025] Specifically, the fuel supply system provides high-pressure biomass oil for the atomizing nozzles 15. After the high-pressure biomass oil is ejected from the atomizing nozzles 15, it forms an umbrella-shaped structure, so that the biomass oil can be in full contact with air. At this time, the biomass oil is ignited through the ignition system, so that the biomass oil can burn fully.

[0026] More specifically, while the biomass oil is burning, local air supply is carried out on the atomizing nozzles 15 through the air supply mechanism, so that the biomass oil can burn more fully.

[0027] The ignition system includes a liquefied gas cylinder 10 disposed inside the box body 1 and an igniter 13 installed in the middle of the right side surface of the partition plate 12. An electromagnetic valve 11 is installed at the gas outlet of the liquefied gas cylinder 10, and the liquefied gas cylinder 10 is connected to the igniter 13 through a conduit.

[0028] Specifically, after the electromagnetic valve 11 is opened, the liquefied gas cylinder 10 supplies liquefied gas to the igniter 13, and the burning liquefied gas ignites the high-pressure biomass oil sprayed out by the atomizing nozzle 15.

[0029] More specifically, the partition plate 12 is a multi-layer composite board including a refractory layer.

[0030] Further, a mounting seat 6 is installed at the lower end of the outer side surface of the box body 1.

[0031] Specifically, through the mounting holes provided on the mounting seat 6, the mounting seat 6 can fix the position of the box body 1.

[0032] Further, the fuel supply system includes a fuel tank 8 and an oil pump 9 installed inside the box body 1. The liquid inlet of the oil pump 9 is connected to the fuel tank 8 through a conduit, the liquid outlet of the fuel tank 8 is connected to a manifold box 18 through a conduit, and the manifold box 18 is connected to the atomizing nozzle 15 through a manifold pipe 17.

[0033] Specifically, the oil pump 9 pressurizes the oil in the fuel tank 8 and injects it into the manifold box 18, and the fuel oil in the manifold box 18 enters different atomizing nozzles 15 through a plurality of manifold pipes 17.

[0034] More specifically, the number of atomizing nozzles 15 is six, and the six atomizing nozzles 15 are evenly distributed in a ring on the right side surface of the partition plate 12, and three air holes 21 are arranged around each atomizing nozzle 15.

[0035] Further, a fuel filling nozzle 2 is provided on the fuel tank 8.

[0036] Specifically, the fuel tank 8 can be refueled through the fuel filling nozzle 2.

[0037] Further, an openable sealing door 7 is provided on the front side surface of the box body 1.

[0038] Specifically, the sealing door 7 is provided with a mechanical lock and a handle, and equipment maintenance can be carried out after the sealing door 7 is opened.

[0039] Further, the igniter 13 includes an outer shell 132, a gas spraying hole 131 and a pulse igniter 133 are provided on the outer shell 132, and the gas spraying hole 131 is connected to the liquefied gas cylinder 10 through a conduit.

[0040] Specifically, the air jet holes 131 are inclined towards the atomizing nozzles 15. Each atomizing nozzle 15 has a corresponding air jet hole 131. The fuel gas ejected from the air jet holes 131 can quickly ignite the biomass oil ejected from the atomizing nozzles 15.

[0041] Further, the air supply mechanism includes a blower 20 installed at the left end of the inner side of the cylindrical barrel 4. The air outlet of the blower 20 is connected to an air guide hood 16 through an air duct 19. The air guide hood 16 is installed on the left side of the partition plate 12, and the air outlet holes 21 communicate with the air guide hood 16.

[0042] Specifically, the blower 20 is a variable-frequency blower. The blower 20 sends air into the air guide hood 16.

[0043] Further, a grille plate 14 is installed on the left side of the cylindrical barrel 4.

[0044] Specifically, the grille plate 14 is used to prevent debris from entering the interior of the blower 20 and causing damage to the fan blades.

[0045] During use: The biomass oil is filled into the interior of the fuel tank 8 through the fuel filling nozzle 2. After the fuel tank 8 is filled with fuel, the fuel filling nozzle 2 is closed. When igniting, first open the solenoid valve 11. The liquefied gas in the liquefied gas cylinder 10 enters through the conduit and is ejected from the air jet holes 131. The pulse igniter 33 is turned on, and the fuel gas is ignited. Subsequently, the fuel pump 9 is started. The fuel pump 9 pressurizes the fuel in the fuel tank 8 and sends it into the distribution box 18. The high-pressure fuel is sent into different atomizing nozzles 15 through the distribution pipes 17 provided on the outer side of the distribution box 18. The fuel oil ejected from the atomizing nozzles 15 spreads out in an umbrella shape and contacts the ignited fuel gas, so that the fuel oil can be quickly ignited.

[0046] At the same time as the fuel oil is ignited, high-pressure air is sent into the air outlet holes 21 through the blower 20. The high-pressure air is ejected through the air outlet holes 21 and is fully mixed with the fuel oil, thereby improving the combustion effect of the fuel.
