Description

Technical Field

[0001] The present invention relates to the technical field of liquid combustion, in particular to a white oil combustion system. Background Art

[0002] Current household combustion systems, such as stoves, water heaters, wall-mounted boilers, and fan heaters, usually use liquefied coal gas, natural gas, or methanol. These fuels are all flammable and explosive hazardous chemicals. If they leak during use, they can cause carbon monoxide poisoning and can ignite with an open flame. New energy white oil and liquid wax are safe and not flammable or explosive. They have high calorific value and cannot be ignited by open flames. They are easy to transport and store and do not produce carbon monoxide. Therefore, combustion systems that use liquid fuels such as white oil and liquid wax as fuel have been introduced on the market. For example, the household new energy white oil and liquid wax stove proposed in patent number CN202221474453.4 uses an oil nozzle and a blower to spray liquid white oil into the burner for mixing and ignition.

[0003] However, this type of combustion system for liquid fuels such as white oil simply sprays the white oil fuel into the burner and uses a blower to mix it with air. This results in uneven mixing of the fuel and air, resulting in poor mixing and low combustion efficiency for the white oil. Therefore, a white oil combustion system with higher combustion efficiency is sought. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a white oil combustion system.

[0005] The technical solution adopted by one embodiment of the present invention to solve the technical problem is: a white oil combustion system, comprising: a liquid storage container, an oil pump, a preheating vaporization device, a nozzle and a burner connected by pipelines;

[0006] The oil pump can suck the white oil from the liquid storage container and transfer it to the nozzle; the preheating vaporization device is arranged between the oil pump and the nozzle, and can heat and atomize the white oil in the pipeline;

[0007] The burner includes an ejector chamber, a compression and acceleration chamber, a high-temperature diffusion chamber, and a combustion chamber; the nozzle can spray white oil toward the ejector chamber; the compression and acceleration chamber is arranged between the ejector chamber and the high-temperature diffusion chamber, and is a connecting passage with a smaller cross-sectional area than the ejector chamber and the high-temperature diffusion chamber, and can compress and accelerate the atomized white oil flowing therein; the high-temperature diffusion chamber is provided with a fire hole communicating with the combustion chamber; the white oil can burn in the combustion chamber and heat the high-temperature diffusion chamber;

[0008] The cross-sectional area of the high-temperature diffusion chamber gradually decreases along the gas flow direction;

[0009] The ejection chamber is located at one end close to the nozzle and is provided with a plurality of air ejection ports.

[0010] Optionally, the pipeline is wound around the outside of the preheating vaporization device.

[0011] Optionally, the pipeline is arranged in a circuitous manner through the preheating vaporization device.

[0012] Optionally, the preheating vaporization device is provided with a temperature detection element.

[0013] Optionally, the heating temperature of the preheating vaporization device is in the range of 70 to 90°C.

[0014] Optionally, the heating temperature of the preheating vaporization device is in the range of 75 to 85°C.

[0015] Optionally, the high-temperature diffusion chamber is partially or completely disposed in the combustion chamber.

[0016] Optionally, the high-temperature diffusion chamber and the combustion chamber are independent cavities and are arranged in close proximity to each other.

[0017] The combustion feeding process of the combustion system of the present invention is specifically as follows:

[0018] S1, sucks the liquid white oil through the oil pump and pumps it toward the front end of the pipeline;

[0019] S2, the preheating vaporization device can heat and atomize the white oil in the pipeline;

[0020] S3, spraying the atomized white oil into the injection chamber through the nozzle, and simultaneously injecting supplementary air and mixing; at this time, the atomized white oil is a white oil-gas mixture in a low-pressure state;

[0021] S4 flows through the compression and acceleration chamber toward the high-temperature diffusion chamber. The small cross-section arrangement of the compression and acceleration chamber can compress and accelerate the atomized white oil, so that the low-pressure white oil mixture is converted into a high-pressure and high-speed white oil mixture.

[0022] S5, the high-pressure and high-speed white oil mixture is diffused in the high-temperature diffusion chamber, and the white oil and air are efficiently mixed and then transported to the combustion chamber through the fire hole;

[0023] S6, when the white oil burns in the combustion chamber, it can heat the high-temperature diffusion chamber again, causing the white oil mixture in the high-temperature diffusion chamber to expand and increase in pressure at high temperature, and then continuously send it to the combustion chamber in a high-pressure mixture state to continue burning.

[0024] The beneficial effects of the present invention are as follows: the combustion system utilizes a compression and acceleration chamber to compress and accelerate the atomized white oil mixture, and utilizes the heat of combustion in the combustion chamber to synchronously heat the high-temperature diffusion chamber, so that the compressed and accelerated atomized white oil mixture is further heated, expanded and pressurized, and is continuously delivered to the combustion chamber in a high-pressure mixture state, so that the white oil and air are fully mixed and delivered at high pressure without the aid of equipment such as a blower, thereby effectively improving the mixing effect of the white oil and air and improving the combustion efficiency of the white oil combustion system.

[0036] Example

[0037] Reference Figures 1 to 3 The present invention proposes a white oil combustion system, comprising: a liquid storage container 10, an oil pump 20, a preheating vaporization device 30, a nozzle 40 and a burner 50 connected by pipelines;

[0038] The oil pump 20 can suck the white oil from the liquid storage container 10 and transfer it to the nozzle 40; the preheating vaporization device 30 is arranged between the oil pump 20 and the nozzle 40, which can heat and atomize the white oil in the pipeline;

[0039] The burner 50 includes an ejector chamber 51, a compression and acceleration chamber 52, a high-temperature diffusion chamber 53 and a combustion chamber 54; the nozzle 40 can spray white oil toward the ejector chamber 51; the compression and acceleration chamber 52 is arranged between the ejector chamber 51 and the high-temperature diffusion chamber 53, and is a connecting passage with a smaller cross-sectional area than that of the ejector chamber 51 and the high-temperature diffusion chamber 53, which can compress and accelerate the atomized white oil flowing inside; the high-temperature diffusion chamber 53 is provided with a fire hole 531 connected to the combustion chamber 54; the white oil can burn in the combustion chamber 54 and heat the high-temperature diffusion chamber 53.

[0040] The combustion feeding process of the combustion system of the present invention is specifically as follows:

[0041] S1, the liquid white oil is sucked in by the oil pump 20 and pumped out toward the front end of the pipeline;

[0042] S2, the preheating vaporization device 30 can heat and atomize the white oil in the pipeline;

[0043] S3, spraying the atomized white oil into the injection chamber 51 through the nozzle 40, and simultaneously injecting supplementary air and mixing; at this time, the atomized white oil is a white oil mixture in a low-pressure state;

[0044] S4 flows through the compression and acceleration chamber 52 toward the high-temperature diffusion chamber 53. The small cross-section arrangement of the compression and acceleration chamber 52 can compress and accelerate the atomized white oil, so that the low-pressure white oil mixture is converted into a high-pressure and high-speed white oil mixture.

[0045] S5, the high-pressure and high-speed white oil mixture diffuses in the high-temperature diffusion chamber 53, and the white oil and air are efficiently mixed and then transported to the combustion chamber 54 through the fire hole 531;

[0046] S6, when the white oil burns in the combustion chamber 54, it can heat the high-temperature diffusion chamber 53 again, causing the white oil mixture in the high-temperature diffusion chamber 53 to expand and increase in pressure at high temperature, and then continue to be sent to the combustion chamber 54 in a high-pressure mixture state to continue burning.

[0047] The combustion system of the present invention utilizes the compression and acceleration chamber 52 to compress and accelerate the atomized white oil mixture, and utilizes the heat from the combustion in the combustion chamber 54 to simultaneously heat the high-temperature diffusion chamber 53, so that the compressed and accelerated atomized white oil mixture is further heated, expanded, and pressurized. In the high-pressure mixture state, it is continuously delivered toward the combustion chamber 54, so that the white oil and air are fully mixed and delivered at high pressure without the aid of equipment such as a blower, thereby effectively improving the mixing effect of the white oil and air and improving the combustion efficiency of the white oil combustion system.

[0048] by Figure 2 and Figure 3 Taking the use of the winning combustion system in a stove product as an example, an ignition component 60 and a control center 70 can be set in the combustion system.

[0049] The channel structure of the compression and acceleration chamber 52 can be arranged into a disc shape, a pipe shape or other communicable channel structures according to the shape of the burner 50.

[0050] To ensure that the preheating vaporization device 30 can quickly and evenly heat the white oil in the pipeline, in some embodiments, the pipeline is coiled outside the preheating vaporization device 30. In other embodiments, the pipeline is arranged in a circuitous manner through the preheating vaporization device 30. Of course, the pipeline can also be arranged in a coiled manner through the preheating vaporization device 30.

[0051] For ease of control, the preheating vaporization device 30 is an electric heating element.

[0052] In some embodiments, the preheating vaporization device 30 is provided with a temperature detection element 31. The temperature detection element 31 can detect the operating temperature of the preheating vaporization device 30 and promptly feed back to the control center 70, thereby adjusting the heating temperature of the preheating vaporization device 30 to keep the heating temperature within a preset temperature value or temperature range.

[0053] After testing and experimentation, in some embodiments, the heating temperature of the preheating vaporization device 30 is in the range of 70 to 90° C., which can quickly atomize the liquid white oil in the pipeline into white oil water mist.

[0054] Preferably, the heating temperature of the preheating vaporization device 30 is in the range of 75 to 85° C. For example, the heating temperature of the preheating vaporization device 30 can be set to 75° C., 77° C., 78° C., 80° C., 81° C., 82° C., 82.5° C., 84° C., or 85° C.

[0055] In this embodiment, the cross-sectional area of the high-temperature diffusion chamber 53 gradually decreases along the gas flow direction. As the white oil mixture flows from the compression and acceleration chamber 52 toward the flame holes 531 in the high-temperature diffusion chamber 53, its cross-sectional area gradually decreases. The white oil mixture is further compressed and accelerated from its high-pressure state and heated by the combustion chamber 54. During this process, the white oil and air are thoroughly mixed.

[0056] In this embodiment, the ejection chamber 51 is provided with a plurality of air ejection ports 511 at one end thereof close to the nozzle 40. The air ejection ports 511 can draw air into the ejection chamber 51 under the traction of the atomized white oil flow ejected from the nozzle 40.

[0057] In some embodiments, for example, the high temperature diffusion chamber 53 is partially or completely disposed in the combustion chamber 54. Figure 3 For example, in a stove product, high-temperature water can be set in the furnace, and the furnace is set in the combustion chamber 54 of the stove base, so that when the combustion chamber 54 burns, the high-temperature diffusion chamber 53 of the furnace can be heated.

[0058] In other embodiments, depending on the layout of the combustion system, the high-temperature diffusion chamber 53 and the combustion chamber can be independent chambers and arranged adjacent to each other. For example, in a vertically stacked combustion system such as a water heater, a combustion structure such as a fire grate can be positioned adjacent to the combustion chamber below, with heating achieved by approaching the combustion chamber 54 on one side.

[0059] In some embodiments, see Figure 3 The burner 50 can be arranged in a split structure, and the inner tank is covered with a combustion fire cover to form a structure of a compression speed increasing chamber 52 and a high temperature diffusion chamber 53.

[0060] The white oil combustion system of the present invention is not limited to being used in household combustion equipment such as stoves, water heaters, wall-mounted boilers, and fan heaters, but can also be extended to be deployed in combustion equipment such as commercial boilers.

[0061] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
