The specific structure of the gas cooling device according to the embodiment of the present utility model will be described below with reference to fig. 1 to 4.
The utility model discloses a gas cooling device, as shown in fig. 1, the gas cooling device of the embodiment comprises a multi-layer tube structure 100 and a connecting tube 200, the multi-layer tube structure 100 defines a gas channel 110 and a liquid storage cavity 120, the gas channel 110 is provided with an air inlet end 111 and an air outlet end 112, the air inlet end 111 is used for introducing high-temperature gas, the liquid storage cavity 120 is provided with a liquid inlet 121, an outlet of the connecting tube 200 is arranged at the air outlet end 112 of the multi-layer tube structure 100, an inlet of the connecting tube 200 is communicated with the liquid storage cavity 120, and an outlet of the connecting tube 200 is communicated with the gas channel 110 to spray liquid towards the gas channel 110.
It should be noted that, taking the liquid in the liquid storage cavity 120 as water as an example, the specific heat capacity of water is 4.2J (g·deg.c), and the vaporization latent heat at 100 deg.c is 2257.2kJ/kg, so the absorption heat energy is far greater than that of the conventional water cooling scheme during vaporization phase transition.
It can be appreciated that in the gas cooling device of this embodiment, when the liquid is sprayed from the outlet of the connection pipe 200 to the gas channel 110, most of the liquid is rapidly vaporized after encountering the high-temperature gas, and a large amount of heat is absorbed in the vaporization process, so that the heat carried by the high-temperature gas is greatly consumed in the liquid vaporization process, and the cooling of the high-temperature gas is rapidly realized. In addition, the existence of the liquid storage cavity 120 can ensure that the temperature of the outer tube of the multi-layer tube structure 100 is relatively safe, the temperature of the outer wall cannot be higher than the boiling point temperature of water, and the temperature of the inner tube of the multi-layer tube structure 100 is reduced, so that the material of the multi-layer tube structure 100 can be made of a conventional stainless steel tube without adopting a special heat-resistant material, the manufacturing cost of the multi-layer tube structure 100 is reduced, the sealing property of the multi-layer tube structure 100 is ensured, and the phenomenon of liquid leakage is avoided.
It should be noted that, in the present utility model, there may be only one or a plurality of connection pipes 200, and when there are a plurality of connection pipes 200, the plurality of connection pipes 200 may be distributed at intervals along the axial direction of the multilayer pipe structure 100, the plurality of connection pipes 200 may be distributed at intervals along the circumferential direction of the multilayer pipe structure 100, and the plurality of connection pipes 200 may be distributed at intervals along the axial direction of the multilayer pipe structure 100 in a plurality of circles, each circle including connection pipes 200 distributed at intervals along the circumferential direction of the multilayer pipe structure 100. Therefore, in the actual use process, the arrangement of the connecting pipes 200 can be selected according to the actual needs, and only a good cooling effect is required to be ensured.
In some embodiments, as shown in FIG. 1, the gas channels 110 are disposed at an incline, and the gas inlet end 111 is higher than the gas outlet end 112. It can be understood that the inclined arrangement of the gas channel 110 can enable the liquid storage cavity 120 located outside the gas channel 110 to be also inclined, and the air inlet end 111 is higher than the air outlet end 112 to avoid backflow of the liquid in the liquid storage cavity 120.
In some embodiments, as shown in fig. 1, the liquid inlet 121 is located upstream of the inlet of the connection pipe 200 in the extending direction of the gas passage 110. It can be appreciated that, since the liquid inlet 121 is located upstream of the inlet of the connecting tube 200, after the liquid enters the liquid storage cavity 120, the liquid storage cavity 120 is filled first and then flows into the connecting tube 200, so that enough cooling liquid can be provided in the liquid storage cavity 120, and thus, the temperature of the inner tube of the multi-layer tube structure 100 can be reduced well.
In some embodiments, as shown in FIG. 1, the highest point of the connecting tube 200 is higher than the planar position of the air intake end 111. It is understood that the highest point of the connection pipe 200 is higher than the highest point of the multi-layered tube structure 100 (the plane position of the inlet end 111), and when the liquid passes through the multi-layered tube structure 100, since the highest point of the connection pipe 200 is higher than the highest point of the multi-layered tube structure 100, it is ensured that the liquid fills the multi-layered tube structure 100 and can be stably injected into the gas passage 110, thereby ensuring the cooling effect.
In some embodiments, as shown in fig. 1-2, the connecting tube 200 includes a first tube segment 210 and a second tube segment 230, the first tube segment 210 being in communication with the reservoir 120, the second tube segment 230 being in communication with the gas channel 110, the first tube segment 210 and the second tube segment 230 being connected at a position above the gas inlet end 111 of the gas channel 110. It will be appreciated that the connection pipe 200 includes the first pipe section 210 and the second pipe section 230, which facilitates connection of the connection pipe 200 with the liquid storage chamber 120 and the gas channel 110, and the connection position of the first pipe section 210 and the second pipe section 230 is higher than the pressure of the liquid ejected from the second pipe section 230 at the gas inlet end 111 of the gas channel 110, so as to increase the total amount of the liquid, thereby increasing contact between the high-temperature gas and the liquid and cooling efficiency.
In some embodiments, the connection pipe 200 further includes a third pipe section 220, two ends of the third pipe section 220 are connected to the first pipe section 210 and the second pipe section (230), respectively, and the third pipe section 220 is higher than the gas inlet end 111 of the gas channel 110. It will be appreciated that the highest point of the connection pipe 200 (the position of the third pipe section 220) is higher than the highest point of the multi-layered pipe structure 100 (the inlet end 111), and that since the highest point of the U-shaped pipe is higher than the highest point of the multi-layered pipe structure 100 after the liquid passes through the multi-layered pipe structure 100, it is ensured that the liquid fills the multi-layered pipe structure 100 and can be stably injected into the gas passage 110, thereby ensuring the cooling effect.
In some particular embodiments, as shown in fig. 1, the third tube segment 220 is disposed horizontally, and both the first tube segment 210 and the second tube segment 230 are perpendicular to the third tube segment 220. Thereby, it is ensured that the liquid fills the multi-layered tube structure 100 and can be stably injected into the gas channel 110, thereby ensuring the cooling effect. Of course, in other embodiments of the present utility model, the angles of the first pipe section 210, the third pipe section 220 and the second pipe section 230 may be selected according to actual needs, and are not limited to the limitation of the present embodiment.
In some embodiments, the connection tube 200 is a bent tube, an inlet of the bent tube is communicated with the liquid storage cavity 120, an outlet of the bent tube is communicated with the liquid storage cavity 120, and a bent position of the bent tube is higher than the air inlet end 111 of the air channel 110. It can be understood that the highest point (bent point) of the connection pipe 200 is higher than the highest point (inlet end 111) of the multi-layered tube structure 100, and when the liquid passes through the multi-layered tube structure 100, since the highest point of the connection pipe 200 is higher than the highest point of the multi-layered tube structure 100, it is ensured that the liquid fills the multi-layered tube structure 100 and can be stably injected into the gas passage 110, thereby ensuring a cooling effect. Meanwhile, the connecting pipe 200 is manufactured by bending a straight pipe, so that the manufacturing of the connecting pipe 200 is facilitated.
In some embodiments, the connection tube 200 is a straight tube, the inlet of which is in communication with the liquid storage chamber 120, and the outlet of which is in communication with the gas channel 110, that is, the connection tube 200 is not limited to the U-shaped tube structure described above in the embodiments of the present utility model.
In some embodiments, as shown in fig. 2-4, the gas cooling apparatus further includes a connection flange 300 connected to the gas inlet end 111 of the gas passage 110, the connection flange 300 being for connection to an output pipe of the high temperature gas. It can be appreciated that the gas cooling device can be ensured to be connected with the output pipeline conveniently by connecting the connecting flange 300 with the output pipeline of the high-temperature gas, and the connection tightness of the gas cooling device and the output pipeline can be improved to avoid the leakage phenomenon of the high-temperature gas. In addition, the connecting flange 300 can also be used as a sealing plate of the liquid storage cavity 120 of the multi-layer tube structure 100, which is beneficial to improving the sealing performance of the liquid storage cavity 120, thereby reducing the probability of liquid leakage.
In some embodiments, as shown in fig. 1, the gas cooling device further includes a blower 400, where the blower 400 is connected to the gas outlet end 112 of the gas channel 110, and the blower 400 is used to drive the forced flow of the gas in the gas channel 110. It will be appreciated that the blower 400 is capable of driving the flow of gas within the gas channel 110, thereby increasing the flow rate of the gas within the gas channel 110, which is beneficial for improving the cooling efficiency.
In some embodiments, as shown in fig. 1, the gas cooling device further includes a gas extraction pipe 500, one end of the gas extraction pipe 500 is connected to the gas outlet end 112 of the gas channel 110, the other end is used for installing the blower 400, and one end of the gas extraction pipe 500 where the blower 400 is installed is lower than one end connected to the gas outlet end 112. It can be appreciated that the fan 400 is connected to the air outlet end 112 of the air channel 110 through the air extraction pipe 500, so that the air flow to the position of the fan 400 is ensured to be at a lower temperature, thereby avoiding the corrosion phenomenon to the fan 400 caused by relatively higher air flow temperature, and being beneficial to prolonging the service life of the fan 400.
In some more specific embodiments, as shown in FIG. 1, the gas cooling apparatus further comprises an exhaust pipe 600, the exhaust pipe 600 being connected to a side of the blower 400 facing away from the exhaust pipe 500. It can be appreciated that the additional exhaust pipe 600 can exhaust toward a designated position, and can exhaust harmful gas into a designated space when harmful gas exists in high temperature gas, thereby improving working safety.
In some embodiments, as shown in FIG. 1, a feed tube 700 is connected to the multi-layer tube structure 100 and communicates with the feed port 121, and the feed tube 700 is connected to an external fluid source. Therefore, in the actual working process, the external liquid source can continuously supplement liquid to the liquid storage cavity 120 through the liquid inlet pipe 700, so that the phenomenon that the cooling effect is reduced due to the lack of liquid in the liquid storage cavity 120 is avoided.
