Description

Technical Field

[0001] The utility model relates to the field of environmental protection accessories for internal combustion engines, in particular to an ozone generator. Background Art

[0002] Internal combustion engines are powered machines that use petroleum products as their main fuel. The power they generate accounts for 90% of the total power of all power mechanical devices in the world. It is becoming increasingly important to improve the combustion efficiency of internal combustion engines and reduce their harmful gas emissions.

[0003] Typical internal combustion engines, such as automobile engines, convert heat energy generated by the combustion of gasoline into mechanical energy, and the combustion process of gasoline requires continuous oxygen supply to maintain. If the oxidizing performance of the oxidant can be improved, such as increasing the oxygen content in the air or adding a certain amount of ozone to the air, the thermal efficiency of gasoline combustion can be significantly improved. The commonly used method at present is to use an ozone generator for high-voltage discharge to prepare ozone from oxygen or air, and high-voltage discharge itself will generate a higher temperature and is not easy to dissipate. Among them, the cavity temperature will directly affect the output rate of ozone. When the ambient temperature is higher than 60°C, ozone will decompose immediately, and the ozone concentration will be greatly reduced, which not only wastes energy, but also is not conducive to the safe and long-term operation of the ozone generator.

[0004] At present, in order to solve the above problems, the Chinese utility model patent (grant announcement number CN 214570748 U) arranges a cooling fan outside the ozone generator and adopts external forced convection to solve the heat dissipation problem of the generator. However, due to the small inner diameter of the inner cavity channel of the generator and the sealing plugs at both ends, it is difficult to reduce the inner cavity temperature by external fan convection. The effect of reducing the temperature of the generator by external forced convection is limited. Utility Model Content

[0005] The utility model aims to solve the problem in the prior art that the high cavity temperature of the ozone generator affects the output rate of ozone, causes ozone decomposition, greatly reduces the ozone concentration, causes energy waste, and is not conducive to the safe and long-term operation of the ozone generator. The utility model provides an ozone generator with an efficient heat dissipation structure, which can avoid ozone decomposition due to excessively high generator temperature and improve the ozone output rate.

[0037] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0038] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0039] Example 1

[0040] See also Figure 1-Figure 2 This embodiment provides an ozone generator, which is installed in an internal combustion engine and is used to provide ozone combustion-aiding to enhance the combustion of the internal combustion engine. The inner cavity of the ozone generator can be forced to supply air for cooling, which effectively reduces the inner cavity temperature of the ozone generator, improves the ozone output rate of the ozone generator, saves energy, and prolongs the service life of the generator. The ozone generator mainly includes: a medium tube 100, an outer electrode tube 200, an inner electrode tube 300, and an inner cavity ventilation tube 400.

[0041] The medium tube 100 is used to separate the medium gas inside it from the external space, and retain the ozone generated by the discharge between the outer electrode tube 200 and the inner electrode tube 300 inside it so as to be transported to the internal combustion engine to improve the combustion efficiency. Figure 1 , Figure 2 As shown in FIG. 1 , the medium tube 100 is a circular tube with two ends opened, and has a first end cap 110 and a second end cap 120 at both ends, which are closed for closing the internal space.

[0042] The outer electrode tube 200 and the inner electrode tube 300 are used to perform high-voltage discharge after being energized, so that the oxygen in the dielectric gas between the two generates ozone. Among them, the outer electrode tube 200 is sleeved outside the dielectric tube 100. The inner electrode tube 300 is arranged in the dielectric tube 100, and its two ends are connected to the first end 110 and the second end 120, so it is also closed by the first end 110 and the second end 120. In addition, an ionization chamber 310 is formed between the outer side of the side wall of the inner electrode tube 300 and the inner side of the side wall of the dielectric tube 100. The ionization chamber 310 has a first air inlet 101 and a first air outlet 103, and is used to input the dielectric gas and output the dielectric gas with ozone, respectively. When in use, the dielectric gas input into the ionization chamber 310 through the first air inlet 101 is between the outer electrode tube 200 and the inner electrode tube 300, so that it can react to generate ozone. In this embodiment, the first air inlet 101 and the first air outlet 103 are respectively arranged on the side wall of the medium pipe 100 near both ends, and both open radially outward along the medium pipe 100 to facilitate the input of medium gas and the output of medium gas with ozone to the internal combustion engine.

[0043] The inner cavity ventilation pipe 400 is arranged in the inner electrode tube 300 as a ventilation and cooling structure of the inner electrode tube 300. One end of the inner cavity ventilation pipe 400 passes through the first terminal 110, extends to the outside thereof and is provided with a second air inlet 401 for introducing cooling air, and a ventilation chamber 430 is formed between the outer side wall of the inner cavity ventilation pipe 400 and the inner side wall of the inner electrode tube 300, so that the cooling air can be concentrated on the inner surface of the side wall of the inner electrode tube 300 for cooling, increasing the flow rate and improving the cooling efficiency. In addition, the ventilation chamber 430 has a second air outlet and a connecting structure. Among them, the connecting structure is connected to the inside of the inner cavity ventilation pipe 400, and is matched with the second air inlet 401 and the second air outlet, so that when in use, the cooling air flows through the inside of the inner cavity ventilation pipe 400, the ventilation chamber 430 and then flows out from the second air outlet in sequence, and two air ducts are formed inside and outside the side wall of the inner cavity ventilation pipe 400, which can keep the cooling air fully flowing, increase the cooling air renewal cycle speed, and improve the cooling efficiency. In this embodiment, the second air outlet is a plurality of air outlet holes 111, which are arranged on the first end 110, and the connecting structure is a gap 405 between the other end of the inner cavity ventilation tube 400 and the second end 120, so that the cooling air can flow along the axial direction of the inner cavity ventilation tube 400, from the side of the second end 120 to the side of the first end 110, thereby flowing through the entire ventilation chamber 430, thereby improving the uniformity of the cooling effect.

[0044] A specific working method of this embodiment is: the medium gas is introduced from the first air inlet 101, and the cooling wind is introduced from the second air inlet 401, and then the required medium gas with ozone can be output from the first air outlet. The cooling wind keeps the temperature in the ionization chamber 310 within a suitable range, avoiding rapid and large-scale decomposition of ozone, so that the ozone concentration in the output gas is sufficient.

[0045] In this embodiment, the ozone generator is provided with a dielectric tube 100, an outer electrode tube 200 and an inner electrode tube 300, and cooperates with the first end 110 and the second end 120 at both ends to form a separated ionization chamber 310 and a ventilation chamber 430. Without affecting the discharge reaction, the cooling wind directly contacts the entire inner side of the side wall of the inner electrode tube 300 and fully flows for cooling, thereby improving the cooling efficiency and effectively reducing the inner cavity temperature of the ozone generator, solving the problem in the prior art that the high cavity temperature affects the ozone output rate, causes ozone decomposition, greatly reduces the ozone concentration, causes energy waste, and is not conducive to the safe and long-term operation of the ozone generator.

[0046] At the same time, in this embodiment, by setting the dielectric tube 100 between the outer electrode tube 200 and the inner electrode tube 300, the ionization chamber 310 and the outer electrode tube 200 and the external environment, that is, the high-temperature space caused by the operation of the internal combustion engine are separated, thereby reducing the influence of the outer electrode tube 200 and the external environment temperature on the dielectric gas in the ionization chamber 310, which is conducive to maintaining its temperature stability.

[0047] In addition, if Figure 1 , Figure 2 As shown in the figure, in this embodiment, a wavy self-cooling strip is also provided on the outer side of the side wall of the outer electrode tube 200 as a heat dissipation structure, and a straight cold strip plate (not shown in the figure) can also be provided, but the wavy self-cooling strip has a higher heat dissipation efficiency than the straight cold strip plate, and can better cooperate with the internal cooling structure to cool down and further reduce the decomposition of ozone.

[0048] Example 2

[0049] See also Figure 3 The second embodiment provides another ozone generator, which is mainly different from the ozone generator of the first embodiment in that the other end of the inner cavity ventilation pipe 400 is connected to the second terminal 120, and the connecting structure is an air inlet 403 on the side wall of the inner cavity ventilation pipe 400. By setting the air inlet 403 for connection, both ends of the inner cavity ventilation pipe 400 have fixed connections, which can improve the stability of the internal structure of the ozone generator. Preferably, the air inlet 403 is set on the side wall of the inner cavity ventilation pipe 400 near the second terminal 120, which can also allow the cooling air to flow through the entire ventilation chamber 430, thereby improving the uniformity of the cooling effect.

[0050] Example 3

[0051] See also Figure 4The third embodiment provides another ozone generator, which is mainly different from the ozone generator of the second embodiment in that: the air inlet holes 403 include multiple groups, and the multiple groups of air inlet holes 403 are evenly arranged along the axial direction of the inner cavity ventilation tube 400, and each group of air inlet holes 403 is evenly arranged along the circumference of the inner cavity ventilation tube 400, thereby forming multiple circulations inside and outside the inner cavity ventilation tube 400, so that the cooling air in the ventilation chamber 430 can be updated and replaced more quickly, further improving the cooling efficiency.

[0052] Example 4

[0053] In the above embodiment, the cooling air and the medium gas are introduced into the ozone generator separately, which results in more complicated pipelines during use and increases the difficulty of installation. In order to further solve these problems based on the first embodiment, a fourth embodiment is provided below.

[0054] See also Figure 5 The main difference between the fourth embodiment and the above embodiments is that the first air inlet 101 and the second air outlet are both arranged at the same position on the side wall of the inner electrode tube 300 to form a connecting hole 301. In the fourth embodiment, the medium gas is used as cooling air. When in use, the medium gas can be cooled in advance, and enters from the second air inlet 401, flows through the inner cavity ventilation tube 400 and the ventilation chamber 430 in sequence, and then reacts in the ionization chamber 310 to generate ozone, which is output from the first air outlet 103. In addition, the connecting hole 301 is arranged close to the first end 110, so that the cooling air can flow through the axial direction of the entire ventilation chamber 430, thereby improving the uniformity of the cooling effect; at the same time, it can also flow through the axial direction of the entire ionization chamber 310 during the reaction process, thereby improving the amount of ozone generated. In addition, in this embodiment, the connecting hole 301 is also arranged in the radial direction opposite to the first air outlet 103, extending the distance of the medium gas flow, increasing its time in the ionization chamber 310, making the reaction more sufficient, and further improving the amount of ozone generated.

[0055] It should be pointed out that the ozone generators of the first to third embodiments have more and more complicated pipeline arrangements compared to the ozone generator of the fourth embodiment. However, since pipelines for the medium gas and cooling air are separately arranged, the ozone generators of the first to third embodiments can adjust the flow rates of the medium gas and cooling air respectively, and have the advantages of being more flexible and more adaptable.

[0056] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
