[0002] With the development of the national economy and the continuous improvement of living standards, vehicles are becoming more and more important in life and travel. Vehicle performance is also an aspect that needs to be considered during vehicle production. When the engine of the vehicle is running, the high-pressure combustible mixed gas in the combustion chamber will enter the crankcase through the gap between the piston assembly and the cylinder to form blowby gas. The blowby gas can be introduced into the combustion chamber after being processed by the oil-gas separation device. However, in winter, the ambient temperature outside the vehicle is low and the humidity is high. When the vehicle is running at high speed under heavy load, the high-temperature and high-humidity gas after separation will freeze in the gas pipeline, which will lead to blockage of the crankcase ventilation system, increased crankcase pressure, crankshaft oil seal disengagement, oil dipstick popping, oil leakage, supercharger damage and other problems, affecting driving performance and economy. The existing measures for dealing with the problem of icing in the gas pipeline are to set a heating structure in the gas pipeline or to set the gas pipeline close to the heat source. The heating structure is complex, and its operation requires energy consumption, which increases the installation cost. Setting the gas pipeline close to the heat source has high requirements for the pipeline installation position, poor installation flexibility, and there is room for improvement.

[0030] The following refers to Figure 1 - Figure 2 to describe the gas treatment device 100 according to an embodiment of the present utility model, which has a simple structure, high setting flexibility, and low setting cost, can improve light weight and reduce energy consumption.

[0031] As Figure 1 - Figure 2 shown, the gas treatment device 100 according to an embodiment of the present utility model includes: a mounting shell 1, a drying member 2, and a heat exchange member 3.

[0032] An installation cavity 13 is formed inside the mounting shell 1, and the mounting shell 1 is formed with an air inlet 141 and an air outlet 151 that communicate with the installation cavity 13. The drying member 2 is installed in the installation cavity 13 and is used for drying the gas. The heat exchange member 3 includes an inner heat exchange part 31 and an outer heat exchange part 32 that are connected. The inner heat exchange part 31 is located inside the installation cavity 13 and the outer heat exchange part 32 extends outside the mounting shell 1. The air flow at the air inlet 141 is adapted to flow through the drying member 2 and the inner heat exchange part 31 and then flow to the air outlet 151.

[0033] Among them, the gas treatment device 100 is arranged between the crankcase and the supercharger. When the engine is running, an oil-gas mixture gas will be generated inside it, and this gas will enter the crankcase through the gap between the piston assembly and the cylinder. After the oil-gas mixture gas in the crankcase is separated by the oil-gas separation device, the gas can enter the gas treatment device 100 through the crankcase ventilation pipe for cooling and drying treatment, and the gas treated by the gas treatment device 100 can flow through the supercharger intake pipe to the supercharger for boosting, and the boosted gas can then flow back to the engine for reaction, ensuring the running reliability of the engine.

[0034] Specifically, the gas treatment device 100 is provided with an installation shell 1. The installation shell 1 is arranged on the outermost side of the gas treatment device 100, which can support and protect the components inside the gas treatment device 100, and can provide installation points for the components inside the gas treatment device 100, ensuring the running reliability of the gas treatment device 100. The installation shell 1 can be set as a rectangle, a cylinder, etc., and can be adjusted according to the actual installation space to improve the setting flexibility. An installation cavity 13 is formed inside the installation shell 1, and the installation shell 1 is formed with an air inlet 141 and an air outlet 151. Both the air inlet 141 and the air outlet 151 are communicated with the installation cavity 13. The gas can enter the installation cavity 13 through the air inlet 141, and then can flow out of the installation cavity 13 through the air outlet 151.

[0035] Furthermore, a drying member 2 is arranged inside the gas treatment device 100. The drying member 2 is arranged inside the installation shell 1, that is, the drying member 2 is located inside the installation cavity 13. The drying member 2 is installed inside the installation cavity 13 and can be set to be detachable relative to the installation cavity 13, which is convenient for later replacement, etc., can extend the service life of the gas treatment device 100, and save the setting cost. The drying member 2 can be set as a mixture of CaO and CaCL2. When the gas flows into the installation cavity 13, the drying member 2 can react with the water in the gas, and then can dry the gas, avoiding problems such as condensation and ice blockage when the gas meets cold in other parts, and improving the use reliability.

[0036] Moreover, a heat exchanger 3 is provided inside the gas treatment device 100. The heat exchanger 3 is provided with an inner heat exchange part 31 and an outer heat exchange part 32. The inner heat exchange part 31 and the outer heat exchange part 32 are connected. The inner heat exchange part 31 is located inside the installation cavity 13, and the outer heat exchange part 32 can extend outside the installation cavity 13. When the ambient temperature outside the gas treatment device 100 is relatively low, the outer heat exchange part 32 can exchange heat with the external environment, making the temperature of the outer heat exchange part 32 relatively low. Since the inner heat exchange part 31 is connected to the outer heat exchange part 32, the temperature of the inner heat exchange part 31 can also be relatively low. As a result, the gas entering the installation cavity 13 can exchange heat with the heat exchanger 3 to cool the gas. The cooled gas can condense into a liquid and adhere to the surface of the heat exchanger 3. At this time, the drying part 2 can also absorb the liquid, thereby preventing the liquid from condensing on other parts of the crankcase and the supercharger and avoiding problems such as blockage of the gas flow path caused by icing on other parts of the crankcase and the supercharger.

[0037] In addition, after the gas enters the installation cavity 13 through the air inlet 141, it can flow through the drying part 2 and the heat exchanger 3. The gas can be dried by the drying part 2, and the heat exchanger 3 can cool the gas. The drying part 2 can dry the liquid condensed after the cooling, so that the gas is transformed into a low-temperature dry gas. The processed gas can then flow out of the gas treatment device 100 through the air outlet 151 and circulate to other devices through a pipeline. The structure of the gas treatment device 100 is simple, with high setting flexibility, and can reduce the setting cost, improve lightweight, reduce energy consumption, and have better use effects.

[0038] According to the gas treatment device 100 of the embodiment of the present invention, by providing the drying part 2 and the heat exchanger 3 inside the installation shell 1, the gas inside the installation cavity 13 can be cooled and dried, so that the gas flowing into the air inlet 141 condenses on the heat exchanger 3 and is dried on the drying part 2, ensuring the dryness of the gas flowing to the air outlet 151 and avoiding problems such as icing and blockage when the gas flowing out of the air outlet 151 encounters cold in other parts. The structure is simple, with high setting flexibility, and can reduce the setting cost, improve lightweight, reduce energy consumption, have better use effects, and a wider application range.

[0039] In some embodiments, the inner heat exchange part 31 is configured as a plate-like structure. The drying part 2 includes a first drying part 21 and a second drying part 23. The first drying part 21 and the second drying part 23 are respectively located on both sides of the inner heat exchange part 31 and are respectively distributed opposite to the inner heat exchange part 31 along the first direction.

[0040] Specifically, as Figure 1As shown, the heat exchanger 3 is provided with an inner heat exchange part 31 and an outer heat exchange part 32 connected to each other. The inner heat exchange part 31 is arranged in the installation cavity 13 and is set as a plate-like structure. The inner heat exchange part 31 can be set as a circular plate-like structure or a rectangular plate-like structure, etc. And the drying part 2 is provided with a first drying part 21 and a second drying part 23, and both the first drying part 21 and the second drying part 23 can also be set as plate-like structures. The first drying part 21 and the second drying part 23 can be respectively arranged on both sides of the inner heat exchange part 31. That is, the first drying part 21 can dry the liquid condensed on one side of the inner heat exchange part 31, and the second drying part 23 can dry the liquid condensed on the other side of the inner heat exchange part 31, improving the drying rate of the drying part 2 and enabling the drying of all parts of the inner heat exchange part 31 to ensure drying reliability.

[0041] Furthermore, setting the inner heat exchange part 31 as a plate-like structure can reduce the space occupied by the inner heat exchange part 31, improve lightweight, and setting the inner heat exchange part 31 as a plate-like structure makes the contact area between the inner heat exchange part 31 and the gas larger, which can improve the heat exchange rate between the inner heat exchange part 31 and the gas. The first drying part 21 and the second drying part 23 are respectively distributed facing the inner heat exchange part 31 along the first direction, and the gap between the first drying part 21 and the second drying part 23 and the inner heat exchange part 31 is small. The area of the first drying part 21 in the first direction can be set to be greater than or equal to the area of the inner heat exchange part 31, and the area of the second drying part 23 in the first direction can also be set to be greater than or equal to the area of the inner heat exchange part 31. Thus, the drying part 2 can dry both sides of the inner heat exchange part 31 comprehensively, ensuring the cooling and drying effect of the gas treatment device 100 on the gas and improving the reliability of the gas treatment device 100.

[0042] In some embodiments, the drying part 2 further includes a connecting part 22. The connecting part 22 is connected between the end of the first drying part 21 and the end of the second drying part 23, and the connecting part 22 is distributed facing the end of the inner heat exchange part 31 along the second direction. The first direction is perpendicular to the second direction.

[0043] Specifically, as Figure 1 - Figure 2As shown, the drying element 2 is provided with a first drying section 21 and a second drying section 23 distributed on both sides of the inner heat exchange section 31 to ensure the reliability of drying the liquid on both sides of the inner heat exchange section 31, and the drying element 2 is also provided with a connecting section 22, which can be set to an arc-shaped or straight plate-shaped structure, and the connecting section 22 is connected between the first drying section 21 and the second drying section 23, so that the drying element 2 can be constructed as an arch structure, and the connecting section 22 and the end of the inner heat exchange section 31 are distributed in a direction opposite to each other. That is, the inner heat exchange part 31 can be placed in the space surrounded by the first drying part 21, the connecting part 22 and the second drying part 23, the first drying part 21 can dry the liquid on one side of the inner heat exchange part 31, the second drying part 23 can dry the liquid on the other side of the inner heat exchange part 31, and the connecting part 22 can dry the liquid at the end of the inner heat exchange part 31, and the first direction is perpendicular to the second direction, that is, the drying element 2 can dry all parts of the inner heat exchange part 31 to ensure drying reliability.

[0044] In some embodiments, the mounting shell 1 includes a connected air inlet side wall 14 and an air outlet side wall 15, the air inlet 141 is provided on the air inlet side wall 14 and is open along a third direction, the air outlet 151 is provided on the air outlet side wall 15 and is open outward along a first direction, and the first direction is perpendicular to the third direction.

[0045] Specifically, the gas processing device 100 is provided with a mounting shell 1, the air inlet 141 and the air outlet 151 are both provided on the mounting shell 1, and the mounting shell 1 is provided with an air inlet side wall 14 and an air outlet side wall 15, the air inlet side wall 14 and the air outlet side wall 15 are connected and arranged, the air inlet 141 can be arranged on the air inlet side wall 14, that is, the gas can flow from the air inlet side wall 14 to the mounting cavity 13, the air outlet 151 can be arranged on the air outlet side wall 15, that is, the gas can flow from the air outlet side wall 15 to the outside of the mounting cavity 13, and the air inlet 141 is opened outwardly along the third direction, and the air outlet 151 is opened outwardly along the first direction. The first drying section 21 and the second drying section 23 are respectively arranged opposite to the inner heat exchange section 31 along the first direction, and the air inlet 141 is open along the third direction, so that when the gas flows into the installation cavity 13, the flow path of the gas is consistent with the extension direction of the first drying section 21, the second drying section 23 and the inner heat exchange section 31, so that the two sides of the inner heat exchange section 31 can cool the gas at the same time, and the first drying section 21 and the second drying section 23 can also dry the gas at the same time, thereby ensuring the reliability of cooling and drying of the gas treatment device 100.

[0046] In some embodiments, the air inlet 141 is disposed in an upper region or a middle region of the air inlet side wall 14 ; and / or the air outlet 151 is disposed in a lower region of the air outlet side wall 15 .

[0047] Specifically, the gas processing device 100 is provided with a connected air inlet side wall 14 and an air outlet side wall 15, and the air inlet 141 is arranged on the air inlet side wall 14, the air outlet 151 is arranged on the air outlet side wall 15, and the air inlet 141 is arranged in the upper area or the middle area of ​​the air inlet side wall 14, and / or the air outlet 151 is arranged in the lower area of ​​the air outlet side wall 15, that is, only the air inlet 141 is arranged in the upper area or the middle area of ​​the air inlet side wall 14, or only the air outlet 151 is arranged in the lower area of ​​the air outlet side wall 15, or the air inlet 141 is arranged in the upper area or the middle area of ​​the air inlet side wall 14, and the air outlet 151 is arranged in the lower area of ​​the air outlet side wall 15.

[0048] Furthermore, in this embodiment, if Figure 2 As shown, the air inlet 141 is arranged in the middle area of ​​the air inlet side wall 14, and the air outlet 151 is arranged in the lower area of ​​the air outlet side wall 15. The gas can flow into the installation cavity 13 through the air inlet 141. The air inlet 141 is arranged in the middle area of ​​the air inlet side wall 14, so that the gas can flow evenly toward various places in the installation cavity 13 after entering the installation cavity 13, thereby accelerating the reaction speed of the gas encountering the drying element 2 and the heat exchange element 3, and the treated gas is low-temperature gas, which is located below the installation cavity 13. The air outlet 151 is arranged in the lower area of ​​the air outlet side wall 15 to facilitate the gas to flow to the outside of the gas processing device 100, thereby improving the gas delivery speed.

[0049] In some embodiments, the mounting shell 1 includes a main shell 11 and a cover plate 12 , which are detachably connected to define a mounting cavity 13 , and a sealing member is provided at the connection between the main shell 11 and the cover plate 12 .

[0050] Specifically, the mounting shell 1 is provided with a main shell 11 and a cover plate 12. The main shell 11 and the cover plate 12 can be connected by connecting parts or snap-on methods, so that the cover plate 12 is detachable relative to the main shell 11, that is, the main shell 11 is formed with an open opening, and the cover plate 12 can be installed at the open opening of the main shell 11 to close the main shell 11, and the cover plate 12 can be separated from the main shell 11, and the open opening can be opened. The main shell 11 and the cover plate 12 jointly define an installation cavity 13, and the drying component 2 is arranged in the installation cavity 13. When the cover plate 12 is separated from the main shell 11, the drying component 2 can be taken out from the open opening, so that the drying component 2 can be replaced, thereby reducing the subsequent maintenance cost, and a sealing component is arranged at the connection between the main shell 11 and the cover plate 12. The sealing component can be set to a rubber ring, etc. The sealing component is arranged around the open opening, thereby improving the sealing of the installation cavity 13, avoiding gas leakage from the open opening to pollute the environment, and improving environmental protection.

[0051] In some embodiments, an installation hole 121 is formed at the bottom of the installation shell 1. The heat exchange member 3 is installed at the installation hole 121. The inner heat exchange portion 31 is located above the installation hole 121 and extends upward. The outer heat exchange portion 32 is located below the installation hole 121 and extends downward.

[0052] Specifically, the installation shell 1 is arranged on the outer side of the gas treatment device 100, which can provide support and protection for the gas treatment device 100, and can enable the gas to be cooled and dried in the installation cavity 13. As Figure 2 shown, an installation hole 121 is provided at the bottom of the installation shell 1, and the heat exchange member 3 is arranged at the installation hole 121, that is, the shape of the installation hole 121 matches the heat exchange member 3. The heat exchange member 3 can extend from the installation hole 121 into the installation cavity 13, so that the inner heat exchange portion 31 of the heat exchange member 3 can be located in the installation cavity 13, and the outer heat exchange portion 32 of the heat exchange member 3 can be located outside the installation shell 1. The inner heat exchange portion 31 extends in a direction away from the installation hole 121 in the installation cavity 13, and the outer heat exchange portion 32 extends in a direction away from the installation hole 121 outside the installation shell 1. Thus, the outer heat exchange portion 32 can conduct the external environmental temperature to the inner heat exchange portion 31 to cool the gas. The structure is simple and the setting cost is low.

[0053] In some embodiments, the heat exchange member 3 is made of a metal material; and / or, the drying member 2 is configured as a porous structure, and the drying member 2 is made of a water-absorbing material.

[0054] Specifically, the heat exchange member 3 can be set as a metal material. The specific heat capacity of the metal material is small, so that the temperature transfer speed of the heat exchange member 3 is fast. When the external environmental temperature is low, the temperature of the heat exchange member 3 will also become lower accordingly. The outer heat exchange portion 32 of the heat exchange member 3 is located outside the installation shell 1 and is affected by the external environmental temperature, so the outer heat exchange portion 32 is relatively low. The inner heat exchange portion 31 of the heat exchange member 3 is located inside the installation shell 1, and the temperature of the outer heat exchange portion 32 can be conducted to the inner heat exchange portion 31. The heat exchange member 3 is made of a metal material with a relatively large specific heat capacity, so that the heat exchange member 3 can maintain a low temperature state. The high-temperature and humid gas can be preferentially adsorbed on the surface of the heat exchange member 3, thereby reducing the gas temperature and avoiding condensation after the gas flows out of the gas treatment device 100, ensuring the reliability of the gas treatment device 100.

[0055] Furthermore, the drying member 2 can be configured as a porous structure, and the drying member 2 can be set as a mixture of CaO and CaCl₂. CaO can react with water in the gas to form Ca(OH)₂. Ca(OH)₂ is a strongly basic substance. Part of the Ca(OH)₂ can undergo a neutralization reaction with acidic substances in the gas, and the remaining part of the Ca(OH)₂ can react with CO₂ in the gas to form CaCO₃ and water. The water generated by the reaction can combine with CaCl₂ to form CaCl₂·nH₂O, thereby making the gas after the reaction a dry neutralized gas, ensuring the reliability of gas drying, and neutralizing harmful components in the gas, improving environmental protection.

[0056] In some embodiments, both the drying member 2 and the heat exchange member 3 are provided in multiple numbers, and the multiple heat exchange members 3 and the multiple drying members 2 are arranged in one-to-one correspondence.

[0057] Specifically, the heat exchange member 3 and the drying member 2 are arranged in the installation shell 1. The heat exchange member 3 can exchange heat with the gas introduced into the installation cavity 13, thereby reducing the gas temperature and enabling the liquid in the gas to condense on the surface of the heat exchange member 3. The drying member 2 can dry the gas and absorb the liquid on the surface of the heat exchange member 3, thereby avoiding problems such as liquid condensation and icing when the gas discharged into the gas pipeline is cooled. The heat exchange member 3 can be provided in multiple numbers, that is, the heat exchange member 3 can be provided in two, three, four, etc., thereby increasing the cooling speed of the gas. The drying member 2 can also be provided in multiple numbers, that is, the drying member 2 can be provided in two, three, four, etc., which can increase the drying speed of the gas and the absorption speed of the liquid on the surface of the heat exchange member 3.

[0058] Furthermore, the multiple heat exchange members 3 and the multiple drying members 2 can be arranged in one-to-one correspondence, that is, the number of the heat exchange members 3 and the drying members 2 is equal. Each heat exchange member 3 is correspondingly provided with a drying member 2. The drying member 2 can be arranged around the corresponding heat exchange member 3, and the gap between the drying member 2 and the heat exchange member 3 is small, thereby increasing the cooling speed of the gas and the drying speed of the gas, and ensuring the reliability of the gas treatment device 100.

[0059] The present utility model also proposes a vehicle.

[0060] The vehicle according to the embodiment of the present utility model includes a crankcase, a supercharger, and the gas treatment device 100 according to any one of the above. The crankcase is communicated with the air inlet 141 through a crankcase ventilation pipe, and the supercharger is communicated with the air outlet 151 through a supercharger inlet pipe.

[0061] Specifically, the crankcase is provided with a crankcase ventilation pipe. One end of the crankcase ventilation pipe is communicated with the crankcase, and the other end is communicated with the air inlet 141 of the gas treatment device 100. After the gas in the crankcase is treated by the oil-gas separation device, the separated gas can flow through the crankcase ventilation pipe to the gas treatment device 100 for treatment. The supercharger is provided with a supercharger inlet pipe. One end of the supercharger inlet pipe is communicated with the supercharger, and the other end is communicated with the air outlet 151 of the gas treatment device 100. The gas treated in the gas treatment device 100 can flow through the supercharger inlet pipe to the supercharger for compression, which can ensure the operation reliability of the crankcase and the supercharger.

[0062] Furthermore, multiple gas treatment devices 100 can be provided, and the multiple gas treatment devices 100 can be connected in series between the crankcase ventilation pipe and the supercharger inlet pipe. Thus, the gas can be cooled and dried multiple times. Also, the multiple gas treatment devices 100 can be connected in parallel between the crankcase ventilation pipe and the supercharger inlet pipe, so that the gas can be cooled and dried separately, improving the treatment efficiency. In actual setting, the multiple gas treatment devices 100 can be set in series and in parallel at the same time, which can improve the cooling and drying speed and ensure the cooling and drying effect at the same time.

[0063] For the vehicle according to the embodiment of the present invention, by arranging the drying member 2 and the heat exchange member 3 in the installation shell 1, the gas in the installation cavity 13 can be cooled and dried. The gas flowing into the air inlet 141 condenses on the heat exchange member 3 and dries on the drying member 2, ensuring the dryness of the gas flowing to the air outlet 151 and avoiding problems such as ice blockage when the gas flowing out of the air outlet 151 encounters cold at other parts. The structure is simple, the setting flexibility is high, the setting cost can be reduced, the weight can be reduced, the energy consumption can be reduced, the use effect is better, and the applicable range is wider.
