DETAILED DESCRIPTION

[0036] The following is a further detailed description of the specific embodiments of the application by comparing the drawings and describing the optimal embodiments.

[0037] The utility model provides a kind of water-cooled gas-water separator, including separator shell 7, cooling mechanism is equipped in separator shell 7;Gas inlet 3, gas outlet 5 and drain outlet 4 are equipped on the separator shell 7;The cooling mechanism includes the water-cooled plate 8 being arranged on separator shell 7, water-cooled pipe line 6, water-cooled inlet 1 and water-cooled outlet 2 are equipped on the water-cooled plate 8;Water-cooled inlet 1 is connected with water-cooled outlet 2 by water-cooled pipe line 6;Gas inlet 3 is connected with the gas acceleration structure for gas acceleration into separator shell 7, and the gas acceleration structure includes turbocharger 12 connected in gas inlet 3;When using, gas enters turbocharger 12 for acceleration by turbocharger inlet, so as to increase the speed of droplet impacting cooling mechanism wall surface, so as to improve the efficiency of water separation.

[0038] The utility model arranges cooling mechanism in gas-water separator, cooling mechanism is passed into cooling liquid, subsequent use, gas enters gas-water separator chamber by gas inlet 3 and impacts water-cooled plate 8, part of liquid drop particle adheres to the surface of water-cooled plate 8 and becomes liquid film, so as to isolate liquid water.

[0039] Meanwhile, by supplying cooling water in water-cooled pipe line 6, the temperature of gas impacting and passing through water-cooled plate 8 is reduced, so that part of gaseous water is condensed into liquid drop, so that the liquid drop adhering to wall surface is increased, so that the efficiency of water separation is increased;By heat exchange, the temperature of water vapor in gas is reduced, so that condensation effect is generated, and the condensed water drop collides with wall surface to form liquid water and flow out from drain outlet 4, so that the efficiency of water separation of gas-water separator is improved.

[0040] In the utility model, separator shell 7 is the main body shell of the whole gas-water separator, and plays a role of containing and protecting internal components, and provides space for the entry, separation and discharge of gas.

[0041] Cooling mechanism is arranged on separator shell 7, and mainly includes water-cooled plate 8, water-cooled pipe line 6, water-cooled inlet 1 and water-cooled outlet 2.

[0042] Water-cooled plate 8 is the main part of cooling mechanism, and water-cooled pipe line 6 is arranged thereon, water-cooled inlet 1 is connected with water-cooled outlet 2 through water-cooled pipe line 6, and cooling liquid (usually water) circulates and flows through water-cooled pipe line 6, so as to reduce the temperature of gas.

[0043] Gas inlet 3 is used for introducing water-containing gas to be separated into the separator;Gas outlet 5 is used for discharging gas after separation treatment;Drain outlet 4 is used for discharging liquid water separated out from the separator.

[0044] Gas acceleration structure is connected to gas inlet 3, and includes turbocharger 12.

[0045] The function is to accelerate the gas entering the separator shell 7, increase the speed of the liquid droplets impacting the cooling mechanism wall, thereby improving the water separation efficiency.

[0046] Working principle

[0047] The mixed gas containing water enters the separator shell 7 through the gas inlet 3.

[0048] Before entering the separator shell 7, the gas is accelerated by the turbocharger 12 in the gas acceleration structure, so that the mixed gas has a higher flow rate and kinetic energy.

[0049] The accelerated mixed gas enters the inside of the separator shell 7 and contacts the water-cooled plate 8 of the cooling mechanism.

[0050] Because the cooling liquid circulates in the water-cooled plate 8, the temperature of the gas is reduced during the contact with the water-cooled plate 8, and the water vapor condenses into liquid droplets.

[0051] The liquid droplets form a liquid film on the surface of the water-cooled plate 8, and as the liquid film thickens, the liquid droplets flow down along the surface of the water-cooled plate 8 under the action of gravity, and finally are discharged from the separator through the drain port 4.

[0052] The dry gas after gas-water separation is discharged from the separator through the gas outlet 5 for subsequent use or treatment.

[0053] The present application has the following main advantages:

[0054] Improve the water separation efficiency; accelerate the gas by the turbocharger 12, so that the liquid droplets impact the water-cooled plate 8 at a higher speed, increasing the collision opportunity and collision strength of the liquid droplets with the water-cooled plate 8, thereby improving the water separation efficiency.

[0055] Reduce the temperature of the gas; the arrangement of the water-cooled plate 8 and the water-cooled pipe 6 can effectively reduce the temperature of the gas, promote more water vapor to condense into liquid droplets, and further improve the gas-water separation effect.

[0056] The water-cooled gas-water separator disclosed in the present application is suitable for various occasions requiring separation and treatment of water-containing gas, such as fuel cell systems, air compression systems, etc., and has important significance for improving system performance and reliability.

[0057] Further, in the present application, the gas outlet end of the turbocharger 12 is connected with a cyclone mechanism 9; the cyclone mechanism 9 comprises a cyclone column 91; the cyclone column 91 is provided with an air inlet channel; the cyclone column 91 is inserted into the gas inlet 3; the turbocharger 12 is connected with the cyclone mechanism 9; the gas outlet end of the turbocharger 12 is connected with the cyclone mechanism 9, which means that the gas accelerated by the turbocharger 12 will directly enter the cyclone mechanism 9, providing power support and specific flow state for the subsequent gas-water separation process.

[0058] The cyclone mechanism 9 mainly comprises a cyclone column 91, the cyclone column 91 is provided with an air inlet channel, and the cyclone column 91 is inserted into the gas inlet 3.

[0059] The structure design enables the gas to smoothly enter the cyclone column 91 from the turbocharger 12 and enter the inside of the separator shell 7 through the air inlet channel.

[0060] The air inlet channel is a channel for the gas to flow from the turbocharger 12 to the inside of the separator shell 7, which not only plays a role in guiding the gas flow, but also can have a certain influence on the flow direction and speed of the gas, thereby affecting the gas-water separation effect.

[0061] The cyclone column 91 is a rotating member; there is airflow at the turbocharger inlet 13, which first drives the turbocharger 12 to rotate under the impact of the airflow; since the cyclone column 91 and the turbocharger 12 are coaxial structures, the turbocharger 12 further drives the cyclone column 91 to rotate.

[0062] Further, in the present application, the air inlet channel comprises a transverse channel; the transverse channel is arranged through the cyclone column 91, the cyclone column 91 is provided with a radial channel, the radial channel is in communication with the transverse channel; the radial channel is oriented differently from the transverse channel; the transverse channel is arranged through the cyclone column 91, which means that the transverse channel extends along the axial direction of the cyclone column 91, thereby providing a main flow path for the gas, enabling the gas to enter the gas-water separator along the axial direction of the cyclone column 91; and then impinge on the water cooling plate 8.

[0063] The cyclone column 91 is further provided with a radial channel, the radial channel is in communication with the transverse channel; the radial channel is generally located between adjacent cyclone fins 92, and the specific arrangement position can be designed as required; the arrangement of the radial channel enables part of the gas to overflow radially along the cyclone column 91, facilitating subsequent movement to the side of the water cooling plate 8 under the action of the blowing structure; in addition, in the present application, the radial channel and the transverse channel play a good shunt effect, avoiding the influence of a single transverse channel on the gas inlet speed.

[0064] The radial channel is oriented differently from the transverse channel, and this design is to guide the gas to produce rotational motion after entering the cyclone column 91, rather than simply flowing along the axial direction; through the arrangement of the different orientations, the gas will be guided by the radial channel after entering the cyclone column 91, thereby generating centrifugal force and forming cyclone.

[0065] The gas first enters the cyclone column 91 through the transverse channel, and then changes the flow direction under the action of the radial channel to produce cyclone motion.

[0066] Due to the different orientations of the radial channel and the transverse channel, the gas will be subjected to strong disturbance after entering the cyclone column 91, which not only helps the separation of liquid droplets, but also makes the water vapor in the gas more easily condensed into liquid droplets.

[0067] Through reasonable design of the transverse channel and the radial channel, the gas can be more uniformly distributed after entering the separator shell 7, avoiding local airflow concentration or dispersion.

[0068] Further, in the present application, the cyclone mechanism 9 includes cyclone fins 92 arranged on the cyclone column 91, and a plurality of cyclone fins 92 are arranged on the circumference of the cyclone column 91, and adjacent cyclone fins 92 are spaced apart; the cyclone fins 92 are arranged on the cyclone column 91, specifically, a plurality of cyclone fins 92 are arranged on the circumference of the cyclone column 91; this means that the cyclone fins 92 are distributed along the circumferential direction of the cyclone column 91, and the cyclone fins 92 play a good flow guiding role, facilitating the movement of the mixed gas discharged from the cyclone column 91 to the side of the subsequent air inlet side blowing mechanism.

[0069] Adjacent cyclone fins 92 are spaced apart; this spaced apart distribution allows the gas to be guided and disturbed by multiple cyclone fins 92 when flowing through the cyclone column 91, thereby making the gas more easily diffuse.

[0070] The spaced apart cyclone fins 92 can also avoid mutual interference between adjacent fins, ensuring that each cyclone fin 92 can effectively function.

[0071] The mixed gas enters the chamber through the gas inlet 3, first passes through and collides with the cyclone mechanism 9; a part of the liquid droplet particles adhere to the surface of the cyclone mechanism 9 to form a liquid film, thereby isolating the liquid water.

[0072] The cyclone mechanism 9 not only plays a role in preliminary separation of liquid droplets, but also can make the gas produce cyclone motion, creating more favorable conditions for the subsequent separation process.

[0073] Further, in the present application, the water-cooled plate 8 is connected to the separator shell 7 at one end and freely extends inside the separator shell 7 at the other end, and the free end of the water-cooled plate 8 is spaced apart from the inner wall of the separator shell 7; the gas inlet 3 and the gas outlet 5 are distributed on opposite sides of the separator shell 7, and the gas inlet 3 and the gas outlet 5 are distributed in a staggered manner; the present application arranges a cooling mechanism in the gas-water separator, and the cooling mechanism is connected to cooling liquid; during subsequent use, the gas enters the gas-water separator chamber through the gas inlet 3 and collides with the water-cooled plate 8, a part of the liquid droplet particles adhere to the surface of the water-cooled plate 8 to form a liquid film, thereby isolating the liquid water.

[0074] At the same time, by supplying cooling water in the water cooling pipeline 6, the temperature of the gas impacting the water cooling plate 8 is reduced, so that part of the gaseous water is condensed into liquid droplets, so that the liquid droplets adhering to the wall surface are increased, thereby increasing the water separation efficiency; through heat exchange, the temperature of the water vapor in the gas is reduced, thereby forming condensation, and the condensed water droplets collide with the wall surface to form liquid water flowing out of the drain port 4, thereby improving the water separation efficiency of the gas-water separator.

[0075] The separator shell 7 is the main structure of the gas-water separator, and the cooling mechanism is arranged in the separator shell 7 in the application; one function of the cooling mechanism is to play a good gas-water separation effect; the gas and water are separated by the wall collision effect of the gas-water separator; the discharged water is discharged from the drain port 4 below the gas-water separator.

[0076] At the same time, the separator shell 7 is provided with a gas inlet 3, a gas outlet 5 and a drain port 4 in the application; the gas inlet 3 is used for the mixed gas to be treated to enter the gas-water separator, and the gas outlet 5 is used for the discharge operation of the treated gas, and the drain port 4 is used for the water liquid separated after condensation to be discharged from the gas-water separator to the outside of the gas-water separator.

[0077] And the cooling mechanism includes a water cooling plate 8, the water cooling plate 8 is provided with a water cooling pipeline 6, a water cooling inlet 1 and a water cooling outlet 2; the water cooling inlet 1 is connected with the water cooling outlet 2 through the water cooling pipeline 6; the water cooling inlet 1 is used for supplying cooling liquid to the water cooling pipeline 6, and the cooling outlet is used for discharging the cooling liquid of the water cooling pipeline 6, and the water cooling pipeline 6 is an internal pipeline, which is convenient for subsequent use of the cooling operation of the gas.

[0078] Further, in the application, one end of the water cooling plate 8 is connected with the separator shell 7, and the other end is freely extended in the separator shell 7, and the free end of the water cooling plate 8 is spaced apart from the inner wall of the separator shell 7; based on such arrangement, the water cooling plate 8 of the application plays a good isolation effect, which is equivalent to dividing the separator shell 7 into two chambers connected at the lower end; at the same time, the water cooling plate 8 also plays a good blocking effect, avoiding the gas directly entering the gas outlet 5 from the gas inlet 3, and the essence is to better realize the gas-water wall collision separation; in addition, in the application, the free end of the water cooling plate 8 is spaced apart from the inner wall of the separator shell 7, so that the free end of the water cooling plate 8 and the inner wall of the separator shell 7 form a gap, which is convenient for the discharge operation of the gas after the wall collision.

[0079] Further, in the application, the gas inlet 3 and the gas outlet 5 are distributed on opposite sides of the separator shell 7, and the gas inlet 3 and the gas outlet 5 are distributed in a staggered manner; based on such a setting, the flow path of gas and water in the gas-water separator can be increased, and the gas-water separation effect is optimized; the gas inlet 3 and the gas outlet 5 are distributed on opposite sides of the separator shell 7, which can make the gas need to pass through a longer path after entering the separator shell 7 before being discharged from the gas outlet 5.

[0080] In this process, the gas has more time to contact the water-cooled plate 8, thereby increasing the cooling and gas-water separation opportunities and improving the efficiency of the entire gas-water separator.

[0081] In addition, in the application, the gas inlet 3 and the gas outlet 5 are distributed in a staggered manner, which can avoid the gas flowing directly from the gas inlet 3 to the gas outlet 5, and reduce the short circuit phenomenon of the gas in the separator shell 7.

[0082] Through the staggered distribution, the gas needs to make multiple turns and collisions in the shell, increasing the contact area and time of the gas with the water-cooled plate 8 and other components, and further improving the gas-water separation effect.

[0083] In the application, the gas inlet 3 is arranged near the free end of the water-cooled plate 8, the gas outlet 5 is arranged away from the free end of the water-cooled plate 8, and the drain port 4 is distributed on the separator shell 7 near the free end of the water-cooled plate 8; based on such a setting, a certain space can be reserved for the inlet side and the outlet side, facilitating the diffusion of mixed gas in the separator shell 7; and facilitating the arrangement and placement of the subsequent blowing structure.

[0084] Based on the above design, the application ensures the distance between the gas inlet 3 and the gas outlet 5 to a certain extent; at the same time, the drain port 4 is located at the bottom of the separator shell 7, facilitating the discharge operation of the condensed water.

[0085] Further, in the application, the blowing structure is arranged inside the separator shell 7; the blowing structure includes an air inlet side blowing mechanism and an air outlet side blowing mechanism; the blowing structure is arranged to blow the mixed gas escaping in the separator shell 7, so that the escaping mixed gas is blown and guided to the cooling plate, realizing the cooling operation of the mixed gas.

[0086] In the application, the main function of the blowing structure is to blow the mixed gas escaping in the separator shell 7; these escaping mixed gases may not directly contact the water-cooled plate 8, or still contain part of the uncondensed water vapor after the initial contact.

[0087] Through the action of the blowing structure, the escaping mixed gas is blown onto the cooling plate, increasing its contact opportunity with the cooling plate, thereby realizing the condensation operation of the mixed gas.

[0088] By guiding the escaping mixed gas to the cooling plate through the blowing structure, more gas can contact the cooling plate, thereby improving the condensation efficiency.

[0089] This design can ensure that the water vapor in the gas is fully condensed, further improving the effect of gas-water separation.

[0090] The blowing structure can also optimize the airflow distribution inside the separator, making the gas more uniformly contact the cooling plate and avoiding local airflow concentration or dispersion.

[0091] This uniform airflow distribution helps improve the performance and stability of the entire gas-water separator, making the gas-water separation effect more uniform and stable.

[0092] The air inlet side blowing mechanism includes an air inlet fan 10 arranged on the separator shell 7.

[0093] The role of the air inlet fan 10 is to blow the mixed gas overflowing from the cyclone mechanism 9, so that this part of the gas can also quickly contact the water cooling plate 8. Through the blowing action of the air inlet fan 10, the escaping mixed gas is guided to the cooling plate, increasing the contact opportunity with the cooling plate.

[0094] The air outlet side blowing mechanism includes an air outlet fan 11 arranged on the separator shell 7.

[0095] The role of the air outlet fan 11 is to continue to guide the mixed gas in the separator shell 7 to the cooling plate, increasing the contact opportunity of the mixed gas with the cooling plate.

[0096] Further, in the present application, the air inlet side blowing mechanism includes a plurality of air inlet fans 10; the air outlet side blowing mechanism includes a plurality of air outlet fans 11; the air inlet fans 10 in the air inlet side blowing mechanism are distributed in a staggered manner with the air outlet fans 11 in the air outlet side blowing mechanism; such arrangement can not only ensure that the mixed gas is better guided to the cooling plate, but also fully utilize a larger area of the cooling plate for mixed gas cooling.

[0097] In addition, the air inlet fan 10 in the air inlet side blowing mechanism and the air outlet fan 11 in the air outlet side blowing mechanism are distributed in a staggered manner; here, the staggered distribution mainly refers to that the air inlet fan 10 and the air outlet fan 11 are not completely arranged in a symmetrical manner, but when projected onto the water cooling plate 8, the air inlet fan 10 and the air outlet fan 11 are partially overlapped or not overlapped; the purpose of such design is mainly to reuse the cooling area of the water cooling plate 8, so as to avoid that the mixed gas on both sides of the water cooling plate 8 is guided on the opposite sides of the water cooling plate 8, and the mixed gas on both sides of the water cooling plate 8 shares a water cooling pipeline 6 on one side.

[0098] Further, in the present application, the air inlet fan 10 in the air inlet side blowing mechanism; the air inlet fan 10 arranged close to the gas inlet 3 has a smaller wind speed than the air inlet fan 10 arranged away from the gas inlet 3; the reason for the above design is to avoid that the air inlet fan 10 arranged close to the gas inlet 3 has a too large wind speed to affect the dispersion of the mixed gas.

[0099] In the present application, the air outlet fan 11 in the air outlet side blowing mechanism; the air outlet fan 11 arranged close to the gas outlet 5 has a smaller wind speed than the air outlet fan 11 arranged away from the gas outlet 5; the air outlet fan 11 arranged close to the gas outlet 5 has a smaller wind speed, so as to reduce the influence of the blowing of the air outlet fan on the air outlet of the gas outlet 5; the air outlet fan 11 arranged away from the gas outlet 5 has a larger wind speed, mainly to better guide the gas to the water cooling plate 8 for secondary cooling and condensation.

[0100] Specifically, in the present application, the air inlet fan 10 arranged close to the gas inlet 3 has a smaller wind speed, so as to avoid that the air inlet fan 10 arranged close to the gas inlet 3 has a too large wind speed to affect the dispersion of the mixed gas.

[0101] At the gas inlet 3, the mixed gas already has a certain flow rate, if the wind speed of the air inlet fan 10 is too large, it may cause the gas flow to be too violent, and even may directly blow the mixed gas to the direction of the gas outlet 5, thereby reducing the opportunity of the mixed gas to contact the water cooling plate 8 and reducing the condensation efficiency.

[0102] The air inlet fan 10 arranged away from the gas inlet 3 has a larger wind speed: so as to blow the gas arranged away from the gas inlet 3 to be close to the water cooling plate 8.

[0103] The mixed gas arranged away from the gas inlet 3 needs a larger wind speed to guide it to flow to the water cooling plate 8, so as to increase the contact opportunity with the water cooling plate 8 and improve the condensation efficiency.

[0104] The air outlet fan 11 arranged close to the gas outlet 5 has a smaller wind speed: so as to reduce the influence of the blowing of the air outlet fan on the air outlet of the gas outlet 5.

[0105] At the gas outlet 5, the gas flow rate after condensation has already been low, and if the air speed of the air outlet fan 11 is too large, it may cause vortex or backflow of the gas at the outlet, affecting the smooth discharge of the gas, and even possibly blowing the already condensed droplets back into the separator, reducing the gas-water separation effect.

[0106] The air speed of the air outlet fan 11 away from the gas outlet 5 is large; mainly to better guide the gas to the water-cooled plate 8 for secondary cooling and condensation.

[0107] The gas away from the gas outlet 5 may not have been fully condensed, and the larger air speed can re-direct these gases to the water-cooled plate 8 for secondary cooling and condensation, further improving the gas-water separation effect.

[0108] By reasonably setting the air speed distribution of the air inlet fan 10 and the air outlet fan 11, the air flow distribution inside the separator can be better optimized, and the flow of the mixed gas inside the separator can be more uniform and stable.

[0109] This optimized air flow distribution helps to improve the performance and stability of the entire gas-water separator.

[0110] A fuel cell assembly includes an air inlet end plate connected with a water-cooled gas-water separator.

[0111] Specifically:

[0112] The application discloses a water-cooled gas-water separator.

[0113] The main problem to be solved by the application is the insufficient water separation efficiency caused by the inability to cool and insufficient collision area in the gas-water separator.

[0114] The specific scheme comprises the following steps:

[0115] A water-cooled gas-water separator comprises a water-cooled inlet 1, a water-cooled outlet 2, a gas inlet 3, a water outlet 4, a gas outlet 5, a water-cooled pipeline 6, a separator shell 7, a water-cooled plate 8, a cyclone mechanism 9, a turbocharger 12 and a blowing structure.

[0116] The water-cooled inlet 1 and the water-cooled outlet 2 are communicated through the water-cooled pipeline 6 and play a cooling role; the separator shell 7 is communicated with the gas inlet 3, an air inlet fan 10, an air outlet fan 11, the gas outlet 5 and the water outlet 4, mixed gas enters the chamber from the gas inlet 3, flows through the cyclone mechanism 9, the air inlet fan 10, the water-cooled plate 8 and the air outlet fan 11 and flows out from the gas outlet 5, and a turbocharger inlet 13 is connected with the gas inlet 3 through a turbocharger.

[0117] Gas enters the turbocharger 12 through the turbocharger inlet to accelerate, thereby increasing the speed of the liquid droplets hitting the wall, thereby improving the water separation efficiency

[0118] The mixed gas enters the chamber through the gas inlet 3, first passes through and hits the cyclone mechanism 9, and a part of the liquid droplet particles adhere to the surface of the cyclone mechanism 9 to become a liquid film, thereby isolating the liquid water.

[0119] The remaining gas has a part advancing and hitting the water-cooled plate 8. Due to the addition of the water-cooled flow channel, the temperature of the mixed gas hitting the water-cooled plate 8 is reduced, so that a part of the gaseous water is condensed into liquid droplets, thereby increasing the liquid droplets adhering to the wall, thereby increasing the water separation efficiency; another part is attracted by the low pressure caused by the rotation of the air inlet fan 10 and is blown to the water-cooled plate 8 by the air inlet fan 10. Due to the addition of the air inlet fan 10, the cross-sectional area and impact speed of the gas hitting the water-cooled plate 8 are greatly increased, thereby further increasing the water separation efficiency.

[0120] The mixed gas flows around the water-cooled plate 8 to the gas outlet 5, a part is attracted by the low pressure caused by the rotation of the air outlet fan 11 and is blown to the water-cooled plate 8 by the air outlet fan 11.
