Detailed Description

Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present application and should not be construed as limiting the application.

In the prior art, as shown in fig. 23, a conventional automobile is designed with a pressure chamber plate 91 of a fan heater, the pressure chamber plate 91 of the fan heater supports a front cover decoration 92, water leaked from the front cover decoration 92 is discharged outside the automobile, and the water-gas separation efficiency of the pressure chamber plate 91 and the front cover decoration 92 is low. Further, in the width direction of the vehicle, the length of the pressure chamber plate 91 and the length of the front cover trim 92 are both long, approaching the width of the vehicle; in the height direction of the vehicle, the height of the pressure chamber plate 91 is large, and in short, the pressure chamber plate 91 occupies a large space. The pressure chamber plate 91 is usually connected to the vehicle body by adopting a plurality of welding modes, so that the weight is heavy, the mounting and dismounting difficulties are high, and the time consumption is long.

As shown in fig. 1, the water-gas separation device adopts a first-stage separation tank and a second-stage separation tank to form a multi-stage separation structure, and a water-gas mixture forms a three-dimensional flow track in the water-gas separation process, so that the water-gas separation efficiency is improved. In addition, the water-gas separation device has compact structure and small occupied space, a pressure chamber plate is omitted, a large amount of space is left, the weight of the whole vehicle is reduced, and the cost is reduced. The water-gas separation device has fewer welding positions, is easier to mount and dismount, and consumes less time.

Referring to fig. 1-21, wherein the open arrow dashed line indicates the direction of air flow and the solid arrow dashed line indicates the direction of water flow, embodiments of a water-gas separation device are provided.

As shown in fig. 3 and 6, the water-gas separation device of the present application includes: a primary separation tank 1 and a secondary separation tank 2. The primary separation tank 1 is provided with a first water outlet 11 and a first separation channel 12; the secondary separation tank 2 is provided with a second water discharge port 21 and a second separation passage 22; wherein the secondary separation tank 2 is in communication with the first separation channel 12; the bottom of the secondary separation tank 2 is positioned below the bottom of the primary separation tank 1; the primary separation tank 1 is configured to perform primary separation on the water-gas mixture to obtain first separated water and primary separated matters, wherein the first separated water is discharged from the first water outlet 11, and the primary separated matters flow out from the first separation channel 12 to the secondary separation tank 2; the secondary separation tank 2 is configured to perform secondary separation on the primary separation product after the primary separation product falls down, to obtain secondary separated water and secondary separation product, wherein the water-gas mixture forms a three-dimensional flow path in the water-gas separation process, the secondary separated water is discharged from the second water outlet 21, and the secondary separation product flows out from the second separation channel 22.

Specifically, the water-air separation device is a device for separating water and air, and when the water-air separation device is applied to a vehicle, if the external environment is rainy, it is necessary to separate water and air, discharge the separated water, and convey the separated air to air-using equipment such as an air conditioning box. The separation tank is a tank structure for separating water and air, and has a notch, a tank bottom and a tank wall, generally, the notch of the separation tank is upward, the bottom of the separation tank is the tank bottom, and the side of the separation tank is the tank wall. The water outlet is a structure for discharging separated water, the separation channel is a circulation channel for separating air from water in air, and most of the water and a small amount of the air are discharged from the water outlet and most of the air and a small amount of the water flow from the separation channel.

In the water-gas separation device of the application, a first-stage separation tank 1 and a second-stage separation tank 2 are arranged, air carrying water is firstly separated in the first-stage separation tank 1, then flows from a first separation channel 12 to the second-stage separation tank 2, is separated in the second-stage separation tank 2, and finally is discharged from a second separation channel 22. The first separated water is discharged from the first water discharge port 11, and the second separated water is discharged from the second water discharge port 21. Because the water-air mixture forms a three-dimensional flow path during the water-air separation process, the air conveyed by the first separation channel 12 needs to change direction in the horizontal plane to flow out of the second separation channel 22; since the bottom of the secondary separation tank 2 is located below the bottom of the primary separation tank 1, the air delivered by the primary separation channel 12 needs to be redirected in a vertical plane to flow out of the secondary separation channel 22. Therefore, the flow direction of air is changed in three-dimensional space through the primary separation tank 1 and the secondary separation tank 2, so that the water separation efficiency of the primary separation tank 1 and the secondary separation tank 2 is improved, and the water-gas separation is more thorough. In addition, the flowing direction of the air is changed in the three-dimensional space, the flowing distance of the air can be increased, and sufficient water separation space and water separation time are reserved. From the aspect of space distribution, the primary separation tank 1 and the secondary separation tank 2 are more compact in structure, and the water-gas separation device can be arranged even on vehicles with narrow space, so that the space utilization rate is higher. The water-gas separation device is connected with the outer plate 6, so that a pressure chamber plate can be omitted, the weight of a vehicle is reduced, the cost of the whole vehicle is reduced (the welding procedure of the vehicle body is reduced), the production efficiency of the whole vehicle is improved (the welding time of the vehicle body is shortened), and the problem that abnormal sound is easily generated by the pressure chamber plate is avoided.

The water and the air are separated by the water-air separation device, so that the water in the air is reduced, the water is prevented from flowing into air-using equipment such as an air-conditioning box and the like, and the working efficiency of the air-using equipment such as the air-conditioning box and the like is higher.

The secondary separation tank 2 may be divided into an upper half and a lower half, and the upper half and the lower half may be detachably connected, for example, by using a connection manner of a buckle and a hook. The unattached portions of the upper and lower halves form a second separation channel 22. The primary separation tank 1 and the secondary separation tank 2 are detachably connected.

In one implementation of the embodiment of the application, the first separation channel 12 and the second separation channel 22 are located on adjacent sides of the secondary separation tank 2, respectively.

Specifically, the first separation channel 12 and the second separation channel 22 are respectively located at two adjacent sides of the secondary separation tank 2, and the first separation channel 12 and the second separation channel 22 are respectively oriented in different directions, so that the primary separated matters flowing out of the first separation channel 12 can only flow out of the second separation channel 22 after changing the flowing direction.

In one implementation of the embodiment of the application, as shown in fig. 3 and 6, the edge of the first separation channel 12 is provided with a first inclined baffle 13.

Specifically, in order to further increase the water separation efficiency of the primary separation tank 1, a first inclined baffle 13 is provided at the edge of the first separation channel 12, a first end of the first inclined baffle 13 is connected to the primary separation tank 1 (the first end of the first inclined baffle 13 is located above the first separation channel 12), and a second end extends toward the bottom of the primary separation tank 1 (i.e., the bottom of the primary separation tank 1), and the distance between the second end of the first inclined baffle 13 and the bottom of the primary separation tank 1 is small. The projection of the first inclined baffle 13 onto the first separation channel 12 covers at least part of the first separation channel 12, and the air in the primary separation tank 1 cannot flow directly out of the first separation channel 12. When the air flows to the first separation channel 12, the air is blocked by the first inclined baffle 13 to split and change the flowing direction, and the first inclined baffle 13 is fully contacted with the air, so that water in the air is contacted with the first inclined baffle 13 and is adhered to the first inclined baffle 13. When the air passes through the first inclined baffle 13, the air is divided into two parts by the first inclined baffle 13, and one part of air is reserved in the primary separation tank 1 and forms turbulence, so that the flow of the whole air in the primary separation tank 1 is changed, and the air in the primary separation tank 1 is fully contacted with the tank wall, the tank bottom and the first inclined baffle 13 to attach and collect moisture in the air; another part of the air is compressed, which is caused by the smaller distance between the second end of the first inclined baffle 13 and the bottom of the primary separation tank 1, and flows out of the first separation channel 12.

In one implementation of the embodiment of the application, as shown in fig. 3,4 and 8, the edge of the second separation channel 22 is provided with a second inclined baffle 23.

Specifically, in order to further increase the water separation efficiency of the secondary separation tank 2, a second inclined baffle 23 is provided at the edge of the second separation channel 22, and a first end of the second inclined baffle 23 is connected to the secondary separation tank 2 (the first end of the second inclined baffle 23 is located above the second separation channel 22) and the second end extends toward the bottom of the secondary separation tank 2 (i.e., the bottom of the secondary separation tank 2). The projection of the second inclined baffle 23 onto the second separation channel 22 covers at least part of the second separation channel 22, and the air in the secondary separation tank 2 cannot flow directly out of the second separation channel 22. When the air flows to the second separation channel 22, the air is blocked by the second inclined baffle 23 to split and change the flow direction, and the second inclined baffle 23 is fully contacted with the air, so that water in the air is contacted with the second inclined baffle 23 to be attached to the second inclined baffle 23. When the air passes through the second inclined baffle 23, the air is divided into two parts by the second inclined baffle 23, and one part of the air is reserved in the secondary separation tank 2 and forms turbulence, so that the flow of the whole air in the secondary separation tank 2 is changed, the air in the secondary separation tank 2 is fully contacted with the tank wall, the tank bottom and the second inclined baffle 23, and moisture in the collected air is attached; another portion of the air flows out of the second separation passage 22.

The second inclined baffle 23 adopts a tile structure and is provided with one or more guide grooves, and the guide grooves are beneficial to enhancing the strength of the second inclined baffle 23 and also beneficial to the downward rapid flow of air and water. The second inclined baffle 23 may also be provided on the primary separation tank 1.

In one implementation of the embodiment of the present application, as shown in fig. 3, the tilting direction of the first tilting baffle 13 is different from the tilting direction of the second tilting baffle 23.

Specifically, the inclination direction of the inclined baffle means a direction in which the inclined baffle is formed to incline between the three-dimensional space and the horizontal plane, and the inclination direction of the inclined baffle may be expressed by a plane in which the inclined baffle is located. Since the first separation channel 12 and the second separation channel 22 are located on adjacent sides of the secondary separation tank 2, respectively, the central axes of the first separation channel 12 and the second separation channel 22 are not coincident or parallel, but form an angle, for example, a right angle, an acute angle or an obtuse angle. The surface of the first inclined baffle 13 and the surface of the second inclined baffle 23 are not parallel or coincident, but form another included angle, so that the inclined direction of the first inclined baffle 13 is different from that of the second inclined baffle 23, and the first inclined baffle 13 and the second inclined baffle 23 can form obstruction to air circulation from different directions, thereby being beneficial to fully attaching moisture in the air.

In one implementation of the embodiment of the present application, as shown in fig. 3, 5, 6, 20 and 21, the bottom of the primary separation tank 1 is provided with a sink tank 14, and the first drain outlet 11 and the first separation channel 12 are both disposed at sides of the sink tank 14.

Specifically, the bottom of the primary separation tank 1 is provided with the sink tank 14, air and water in the primary separation tank 1 flow from the bottom of the primary separation tank 1 to the sink tank 14 more easily, the sink tank 14 plays roles of changing the air flow direction and converging running water, the converging running water flows into the sink tank 14 and then mainly flows to the first water outlet 11, and the air flows into the sink tank 14 and then mainly flows to the first separation channel 12. The first inclined baffle 13 is located above the sink 14, and the water drops attached to the first inclined baffle 13 fall into the sink 14 along the first inclined plate and continue to flow to the first drain opening 11. Due to the existence of the sink groove 14, the water drops falling down on the first inclined baffle 13 are blocked in the sink groove 14, and are not likely to flow out from the first separation channel 12 with the air.

The first water outlet 11 and the first separation channel 12 are respectively positioned at two adjacent sides of the primary separation tank 1, the sink tank 14 is positioned at one corner of the primary separation tank 1, and the sink tank 14 is positioned between the first water outlet 11 and the first separation channel, so that the first water outlet 11 and the first separation channel 12 are respectively positioned at two adjacent sides of the sink tank 14. The bottom of the primary separation tank 1 is obliquely arranged, and the primary separation tank 1 is inclined towards the first water outlet 11, so that water in the primary separation tank 1 can flow towards the first water outlet 11; the primary separation tank 1 is inclined toward the first separation channel 12, so that air in the primary separation tank 1 can flow toward the first water discharge port 11.

In one implementation of the embodiment of the present application, as shown in fig. 3, 5 and 6, the first inclined baffle 13 extends downward toward the sink tank 14 from the side where the first separation channel 12 is located to the side away from the first separation channel 12.

Specifically, the first inclined baffle 13 is inclined downward from the side of the first separation channel 12 to the side away from the first separation channel 12, and extends toward the sink tank 14, so that the water collected on the first inclined baffle 13 flows downward and falls into the sink tank 14. Since the lower end (second end) of the first inclined baffle 13 is located at a side of the sink groove 14 away from the first separation channel 12, water that the first inclined baffle 13 falls into the sink groove 14 does not easily flow directly to the first separation channel 12 with air, but more easily falls into the sink groove 14 and flows out of the first drain opening 11.

In one implementation of the embodiment of the present application, as shown in fig. 3 and 8, the second inclined baffle 23 is inclined downward from the side where the second separation channel 22 is located to the side away from the second separation channel 22.

Specifically, the second inclined baffle 23 is inclined downward from the side where the second separation passage 22 is located to the side away from the side where the second separation passage 22 is located, so that the water collected on the second inclined baffle 23 flows downward to fall into the secondary separation tank 2. Since the lower end (second end) of the second inclined baffle 23 is located at a side of the second separation tank 2 remote from the first separation channel 12, the water falling into the second separation tank 2 by the second inclined baffle 23 does not easily flow directly to the second separation channel 22 with the air, but more easily falls into the second separation tank 2 and flows out from the second drain outlet 21.

In one implementation of the embodiment of the present application, as shown in fig. 13 to 16, a drain valve 24 is provided on the second drain port 21.

Specifically, the second drain port 21 is provided with a drain valve 24, and specifically, a pipe body may be sleeved on the second drain port 21, and the drain valve 24 may be connected with the pipe body. The drain valve 24 is opened at the time of draining water to drain water in the secondary separation tank 2; the drain valve 24 is closed when not draining water, preventing air from entering the secondary separation tank 2 from the second drain port 21. Since the second separation passage 22 is usually communicated with air-using equipment such as an air conditioning box, the closing of the drain valve 24 allows air to be substantially separated from water and air by the primary separation tank 1 and the secondary separation tank 2 and then introduced into the air-using equipment, instead of being introduced into the secondary separation tank 2 by the second drain port 21. When the water-air separation device is used in an automobile, the second water outlet 21 is usually located in a cabin, and the cabin is provided with an engine, a motor and other devices, the air in the cabin is not necessarily fresh air, and therefore, the air in the cabin needs to be restricted from flowing into the air-consuming device by the water outlet valve 24.

In one implementation of the embodiment of the present application, as shown in fig. 15 to 16, the drain valve 24 includes: sleeve 241, valve cap 242 and balancing weight 243. The valve cover 242 is rotatably connected with the sleeve 241; the balancing weight 243 is connected with the valve cover 242; the valve cover 242 rotates under the gravity of the weight 243 and covers the sleeve 241.

Specifically, the drain valve 24 adopts an automatically opened and closed valve, and after the water in the secondary separation tank 2 (specifically, a pipe body) reaches a preset weight, the valve cover 242 is pushed to rotate so as to open the valve cover 242, so that the water in the secondary separation tank 2 is drained; when the water in the secondary separation tank 2 (specifically, the pipe body) is discharged, the valve cover 242 is driven to rotate under the action of the balancing weight 243 so as to close the valve cover 242. The drain valve 24 is automatically opened after a certain amount of accumulated water is formed in the secondary separation tank 2, and the drain valve 24 is automatically closed after the accumulated water is discharged.

In one implementation manner of the embodiment of the present application, as shown in fig. 3, 8, and 11-14, the water-gas separation device further includes: and a three-stage separation tank 3. The third separation tank 3 is provided with a third separation channel 31; wherein the three-stage separation tank 3 is communicated with the second separation channel 22; a return water channel 32 is arranged between the three-stage separation tank 3 and the two-stage separation tank 2, and the third separation water falls down and passes through the return water channel to be mixed with the second separation water.

Specifically, a tertiary separation tank 3 is provided between the secondary separation tank 2 and the air consuming apparatus to further separate water in the air, and the water separated by the tertiary separation tank 3 (i.e., the third separated water) flows back to the secondary separation tank 2 from the return water passage 32 and is discharged from the second water discharge port 21. The water-air separation device is connected to the front wall plate of the vehicle and is connected with the air conditioning box, so that the arrangement space of the front wall plate is improved, and the space utilization rate of the front wall plate is improved. When the air has been subjected to at least two separations before the three-stage separation tank 3, and the three-stage separation tank 3 is subjected to the final moisture separation, the moisture in the air is reduced, and the water separated by the three-stage separation tank 3 (i.e., the third separated water) is also reduced, so that the water separated by the three-stage separation tank 3 (i.e., the third separated water) is discharged to the second-stage separation tank 2 through the return water passage 32 without adding a water outlet to the three-stage separation tank 3, and finally discharged from the second water outlet 21. The third-stage separation tank 3 includes an upper half portion and a lower half portion, the upper half portion of the third-stage separation tank 3 is connected with the upper half portion of the second-stage separation tank 2, and the lower half portion of the third-stage separation tank 3 is connected with the lower half portion of the second-stage separation tank 2.

In one implementation of the embodiment of the present application, as shown in fig. 8, 12 and 14, the width of the second separation channel 22 is smaller than the width of the third separation channel 31.

Specifically, since the moisture of the air in the three-stage separation tank 3 is already small, the width of the third separation passage 31 is large in order to facilitate the air circulation, and the width of the second separation passage 22 is small in order to secure the water-gas separation efficiency of the two-stage separation tank 2.

In one implementation manner of the embodiment of the present application, as shown in fig. 3, 7 and 12, the water-gas separation device further includes: pre-separation tank 4. The pre-separation tank 4 is provided with a third water outlet 41; the pre-separation tank is configured to pre-separate air containing water to obtain a pre-separated water and water-air mixture; wherein the water-gas mixture flows over the pre-separated water and falls to the first-stage separation tank, and the pre-separated water falls and is independently discharged from the third water outlet 41.

Specifically, the pre-separation tank 4 pre-separates the air containing water, separates the pre-separation water and the water-gas mixture, and performs the first-stage separation after the water-gas mixture falls down, and the water separated by the pre-separation tank 4 (i.e., the pre-separation water) is independently discharged from the third water outlet. When the primary separation tank 1, the secondary separation tank 2, the tertiary separation tank 3 and the pre-separation tank 4 are adopted, the water-gas separation times are more, and the water-gas separation efficiency is higher. The main separation tasks of the separation tanks are slightly different due to different water-gas separation sequences. The water-gas separation is firstly carried out in the pre-separation tank 4, and the main task of the pre-separation tank 4 is water drainage; the water-gas separation of the primary separation tank 1 and the secondary separation tank 2 is carried out after the water-gas separation of the pre-separation tank 4, and the primary task of the primary separation tank 1 and the secondary separation tank 2 is the water-gas separation; the water-gas separation of the three-stage separation tank 3 is positioned at the end, and the main task of the three-stage separation tank 3 is to discharge air.

In one implementation of the embodiment of the present application, as shown in fig. 3, 7 and 12, a water baffle 61 is disposed between the pre-separation tank 4 and the primary separation tank 1; the upper part of the water baffle 61 forms a fourth separation channel, and the water-gas mixture in the pre-separation tank 4 passes through the fourth separation channel and then falls to the primary separation tank 1.

Specifically, in order to further improve the separation efficiency of water and gas, a pre-separation tank 4 is provided, and air is initially separated and then enters the primary separation tank 1. Since the water-gas separation of the pre-separation tank 4 is performed before the water-gas separation of the primary separation tank 1, the water in the air may be more and the water is mainly discharged as soon as possible, so that the water baffle 61 is disposed between the primary separation tank 1 and the pre-separation tank 4, and even if the water is not discharged from the third water outlet in time, the water is not easy to enter the primary separation tank 1 beyond the water baffle 61 due to the blocking of the water baffle 61.

The water baffle 61 is usually arranged on the outer plate 6 of the cabin drainage air inlet system, the primary separation tank 1 and the pre-separation tank 4 are arranged on the outer plate 6, and the water baffle 61 is abutted against a position between the primary separation tank 1 and the pre-separation tank 4. The water deflector 61 may also be connected to the pre-separation tank 4 or to the primary separation tank 1. When the cabin drainage and air intake system is applied to a vehicle, the cabin drainage and air intake system is installed below the front cover, and a space is formed between the front cover and the water baffle 61 to form a fourth separation channel.

In one implementation of the embodiment of the present application, as shown in fig. 3, 4 and 7, both the pre-separation tank 4 and the primary separation tank 1 are located on the same side of the secondary separation tank 2.

Specifically, the pre-separation tank 4 and the first-stage separation tank 1 are both located on the same side of the second-stage separation tank 2, air is firstly subjected to water-air separation through the pre-separation tank 4, and the air separated through the pre-separation tank 4 enters the first-stage separation tank 1 from the fourth separation channel, so that the air does not change the flow direction greatly, and can enter the first-stage separation tank 1 from the pre-separation tank 4 quickly. When passing through the primary separation tank 1 and the secondary separation tank 2, the flow direction of air can be changed greatly, and the water-gas separation efficiency is improved. The air flowing out of the secondary separation tank 2 flows to the air utilization device through the tertiary separation tank 3, and the flowing direction of the air is not changed greatly.

In one implementation of the embodiment of the application, as shown in fig. 1, 2 and 7, the notches of the preseparation tank 4 are provided with a first grating 62.

Specifically, the notch of the pre-separation tank 4 is provided with a first grating 62 to prevent impurities in the air from entering the pre-separation tank 4 to block the third water outlet 41. The first grille 62 may be provided on the outer plate 6 of the cabin drainage air intake system, the first grille 62 abutting against the notch of the pre-separation tank 4. The first grating 62 may also be connected to the preseparation tank 4.

In one implementation of an embodiment of the present application, as shown in fig. 7, the first grating 62 has a V-shaped cross section.

Specifically, the cross section of the first grating 62 is V-shaped, so that the first grating 62 and the water baffle 61 form a trapezoid structure, and water can flow to the first grating 62 and reach the pre-separation tank 4. When the first grille and the water baffle 61 are arranged on the outer plate 6 of the cabin drainage air inlet system, the outer plate 6 can be larger in size, and water in a larger range is gathered to the pre-separation tank 4to be discharged, so that the pre-separation tank 4 mainly plays a role in drainage, and the first grille 62 and the water baffle 61 form a trapezoid structure, so that water in other areas is gathered to the first grille 62 and falls into the pre-separation tank 4.

In one implementation of the embodiment of the present application, as shown in fig. 1, 2, 6 and 7, the notch of the primary separation tank 1 is provided with a second grill 63.

Specifically, the notch of the primary separation tank 1 is provided with the second grill 63, which can further prevent sundries in the air from falling into the primary separation tank 1 while blocking the first drain opening 11. A second grid 63 may be provided on the outer plate 6 of the cabin drainage air intake system, the second grid 63 covering the notches of the pre-separation tank 4. The second grill 63 may also be connected to the primary separation tank 1.

In one implementation of an embodiment of the present application, as shown in fig. 7, the height of the second grating 63 is higher than the height of the first grating 62.

Specifically, the height of the second grill 63 is higher than that of the first grill 62, so that there is a larger space in the primary separation tank 1, and the air in the primary separation tank 1 has a larger flow space, and the moisture and air separation efficiency is higher.

In one implementation of the embodiment of the application, as shown in fig. 7, the second grating 63 slopes downward from the end of the water baffle 61 to the end remote from the preseparation groove 4.

Specifically, the second grille 63 is obliquely disposed, the height of the side of the second grille 63 close to the pre-separation tank 4 is higher, the height of the side of the second grille 63 away from the pre-separation tank 4 is lower, and when the second grille 63 contacts with air, moisture is attached and collected, the moisture flows in a direction away from the pre-separation tank 4, and the first water outlet 11 is located close to the pre-separation tank 4, so that water on the second grille 63 tends to flow in a direction away from the pre-separation tank 4 (i.e. away from the first water outlet 11), which is beneficial to the attachment and collection of water.

In one implementation manner of the embodiment of the present application, as shown in fig. 3, 7, 11 and 12, the water-gas separation device further includes: and a drain chamber 5. The water discharge chamber 5 is communicated with the first water discharge port 11; wherein the drain chamber 5 is provided with a fourth drain opening 51; the bottom of the water draining chamber 5 is positioned below the bottom of the primary separation tank 1; the first separated water flows down to the drain chamber 5 and flows back, and is then independently discharged from the fourth drain port 51.

Specifically, in order to facilitate the discharge of the water of the first drain port 11 and reduce the discharge of the air, a drain chamber 5 is disposed below the preseparation groove 4, and a fourth drain port 51 is provided at the bottom of the drain chamber 5. If the first separation tank 1 separates a large amount of water (i.e., first separation water), the water can be stored in the drain chamber 5 and discharged through the fourth drain port 51, and the stored water is located below the drain chamber 5, so that air is not easily discharged through the fourth drain port 51. The fourth drain opening 51 may be provided in one or two, and is specifically configured as needed. The primary separation tank 1 is higher in position, the drain chamber 5 is shorter in position, and water in the primary separation tank 1 easily flows into the drain chamber 5.

In one implementation of an embodiment of the application, as shown in fig. 3, 7, 11 and 12, the drain chamber 5 is located directly below the preseparation tank 4.

Specifically, the drain chamber 5 and the primary separation tank 1 may form an integral structure, and the pre-separation tank 4 is placed directly above the drain chamber 5, so that a space, i.e., the first drain port 11, is formed between the pre-separation tank 4 and the primary separation tank 1. As shown in fig. 20 and 21, the sink 14 has a notch, which is a C-shaped groove, and the notch is communicated with the drainage chamber 5, so that water in the sink 14 can flow into the drainage chamber 5, and the overall structure is more compact. The wall of the settling tank 14 is an inclined wall, so that the flow rate of water in the settling tank 14 to the pre-separation tank 4 is improved, and the inclined wall is a C-shaped inclined wall.

In addition, as shown in fig. 1 to 21, based on the water-gas separation device of any one of the above embodiments, an embodiment of the present application further provides a cabin drainage air intake system, which includes the water-gas separation device of the above embodiment.

When the cabin drainage air intake system is applied to a vehicle, the support plate 7 is mounted on the vehicle body. The support plate 7 is connected with the outer plate 6, and specifically, clamping and screwing can be adopted.

In one implementation of the embodiment of the present application, as shown in fig. 2, 7 and 17, a water deflector 61 is formed on the outer panel 6.

Specifically, the water deflector 61 is formed on the outer panel 6. When the primary separation tank 1 and the pre-separation tank 4 are installed at the outer plate 6, the primary separation tank 1 and the pre-separation tank 4 are located at both sides of the water baffle 61, respectively.

Specifically, when the cabin drainage air intake system is applied to a vehicle, the cabin drainage air intake system is located below the front cover, a space is formed between the front cover and the dash panel 61, and a fourth separation passage is formed. The outer plate 6 is also provided with a sealing strip, the sealing strip is positioned on one side of the primary separation groove 1 away from the water baffle 61, and the sealing strip abuts against the front cover of the automobile to prevent water from entering the engine room.

The drainage groove 8 is arranged on the outer plate 6; wherein the drainage tank 8 and the primary separation tank 1 are respectively positioned at two ends of the outer plate 6; the drain tank 8 is provided with a fifth drain port 81.

Specifically, since the water-gas separation device is located at one end of the outer plate 6, the other end of the outer plate 6 also needs to be drained, a drain tank 8 is provided at one end of the outer plate 6 away from the primary separation tank 1, and a fifth drain port 81 is provided at the bottom of the drain tank 8.

In addition, as shown in fig. 1 to 21, based on the water-air separation device or the cabin drainage air intake system of any one of the above embodiments, the embodiment of the present application also proposes a vehicle, which includes the water-air separation device or the cabin drainage air intake system of the above embodiment.

Based on the water-gas separation device of any embodiment, the application provides some embodiments of a water-gas separation method.

As shown in fig. 22, the water-gas separation method of the present application comprises the steps of:

S100, carrying out primary separation on the water-gas mixture based on the primary separation tank to obtain first separated water and primary separated matters.

S200, based on a secondary separation tank, carrying out secondary separation on the primary separation object after the primary separation object falls down to obtain second separation water and a secondary separation object; wherein, the water-gas mixture forms a three-dimensional flow track in the water-gas separation process.

Specifically, the water-air mixture refers to air mixed with water, the water-air mixture can be mainly air, and the volume of the air accounts for more than half of the total volume of the mixture. The water-gas mixture is sequentially subjected to primary separation and secondary separation, wherein the primary separation can separate first separated water, the secondary separation can separate second separated water, and the water is separated as much as possible by adopting a multi-stage separation mode. In the water-gas separation process, the flowing direction and the track of the water-gas mixture are changed in a three-dimensional space, and more water is separated when a multi-stage separation mode is combined, so that the water-gas separation efficiency is improved, and the water-gas separation is more thorough. The primary separation product still contains a certain amount of water, and further secondary separation is carried out, wherein the water content of the secondary separation product is lower than that of the primary separation product, and the secondary separation product can be directly conveyed to gas utilization equipment when the water content of the secondary separation product meets the requirement. The weight of the second separated water is typically less than the weight of the first separated water. When the flow track of the three-dimensional space is formed, the water-gas mixture (or the primary separation object) forms a certain amount of displacement in three dimensions, and compared with the flow track of the two-dimensional plane, the flow track of the three-dimensional space has larger obstruction to water flow, thereby being beneficial to improving the water-gas separation efficiency. When the air conditioner is applied to a vehicle, the air conditioner box can suck air, and because the flow track of the three-dimensional space is formed, even if the suction force of the air conditioner box is large, water is not easy to suck into the air conditioner box, so that the water-air separation efficiency is less influenced by the suction force of the air conditioner box, and the water-air separation efficiency is always at a high separation level.

As shown in fig. 22, the water-air mixture flows in the x-axis direction to perform primary separation to obtain a primary separated product and first separated water, and the primary separated product falls in the direction opposite to the z-axis direction to perform secondary separation to obtain a secondary separated product and second separated water. The water-gas mixture is displaced in the x-axis, y-axis and z-axis during the water-gas separation process.

In one implementation of an embodiment of the application, the first separated water is discharged separately after flowing downwards and back.

Specifically, the first separated water flows downward for a certain distance, then turns back and flows downward, and finally is discharged. When the retracing and downward flowing modes are adopted, the flowing distance of the first separated water is prolonged, the flowing of the first separated water is more gentle, the first separated water is attached and converged as much as possible, and the water-gas separation efficiency is improved.

As shown in fig. 22, the first separated water flows downward, particularly under the influence of gravity. After the first separation water is separated, the first separation water flows back and is opposite to the flow direction during the primary separation of the water-gas mixture.

The water-gas separation method of the application further comprises the steps of:

S300, carrying out three-stage separation on the secondary separation object based on the three-stage separation tank to obtain third separation water and a third separation object; wherein the third separated water falls down and is mixed with the second separated water and discharged.

Specifically, the secondary separation product can be a product containing a small amount of water, and in order to further reduce the water content, air with lower water content is output, and the secondary separation product is subjected to three-stage separation to obtain a three-stage separation product, wherein the water content of the three-stage separation product is lower than that of the secondary separation product, and the three-stage separation product is directly conveyed to gas utilization equipment. The weight of the third separated water is usually less than that of the second separated water, and because the water-gas mixture is subjected to the primary separation and the secondary separation before, the third separated water has very little weight (the sum of the weight of the third separated water and the weight of the second separated water is less than that of the first separated water) in the tertiary separation, the third separated water can be mixed into the second separated water and discharged together, and the third separated water does not need to be discharged independently, so that the weight of the first separated water is higher, and the independent discharge mode is quite suitable.

As shown in fig. 22, the primary separator flows in the y-axis direction substantially when the secondary separation is performed, and also flows in the y-axis direction substantially when the tertiary separation is performed, and the water content in the secondary separator is small, so that the flow direction of the secondary separator can be not changed when the tertiary separation is performed. The third separated water flows in a direction substantially opposite to the y-axis and is mixed with the second separated water.

The water-gas separation method of the application further comprises the steps of:

s10, based on a pre-separation tank, pre-separating the air containing water to obtain a pre-separated water and water-air mixture; wherein the water-gas mixture flows over the pre-separated water and falls down.

Specifically, the ratio of the volume of air to the volume of water in the water-containing air may be greater than 1 or less than 1, that is, the water-containing air may be mainly air or mainly water. The pre-separation is carried out on the air containing water, the pre-separation mainly plays roles of separation and drainage, the weight of the pre-separation water is larger than that of the first separation water, and particularly, most of water can be separated by the pre-separation in rainy days. The pre-separation is mainly carried out by utilizing the gravity of water, the water content in the water-containing air is higher, and the water drops or converged running water which possibly show larger particles have larger weight and are not easy to flow along with the air, and are easy to fall under the influence of the gravity, so that the pre-separation water is formed. The water-air mixture (water in the water-air mixture is small-particle water drops and easily flows along with air) flows above the pre-separated water, and the water-air mixture also flows downwards or falls down after passing over the pre-separated water.

As shown in fig. 22, the air containing water is pre-separated by flowing in a direction generally opposite to the y-axis to obtain a pre-separated water and water gas mixture. The water-gas mixture falls in a direction generally opposite to the z-axis and undergoes a first separation. The water-gas mixture falls from above before the first stage separation, and the water-gas mixture falls again after the first stage separation, so that a double-layer structure having an upper layer and a lower layer can be formed.

In one implementation of the embodiment of the application, the pre-separated water is discharged independently after falling.

Specifically, the pre-separation water adopts an independent discharge mode, the weight of the pre-separation water is large, the pre-separation water occupies a large part of the total separation water, and the pre-separation water can be discharged more quickly by adopting the independent discharge mode. As shown in fig. 22, the pre-separated water is independently discharged after falling.
