Detailed implementation mode
[0022] The following further elaborates on the present utility model in conjunction with the attached drawings.
[0023] Embodiment:
[0024] Referring to Figure 1 - Figure 4 A cooling tower unit capable of cyclic refrigeration disclosed by the present utility model includes a housing 1. A heat exchange chamber 2 is provided inside the housing 1. A partition 3 is fixedly connected to the middle of the heat exchange chamber 2. A refrigeration assembly 4 is arranged inside the partition 3. An air inlet 5 communicating with the heat exchange chamber 2 is provided at the top of the housing 1. An air extraction pipe 6 for cooling the hydrogen breaking unit is fixedly connected to the outer wall of the housing 1 above the partition 3.
[0025] A through hole 7 is provided in the middle of the partition 3. The top of the partition 3 is gradually inclined downward from the outside to the inside with the through hole 7 as the center to form a guiding surface 8 for guiding water flow.
[0026] In this embodiment, by observing Figure 1 and Figure 2 , it can be found that a heat exchange chamber 2 is provided inside the housing 1, and the refrigeration assembly 4 is connected through the partition 3 inside the heat exchange chamber 2, enabling the refrigeration assembly 4 to refrigerate inside the heat exchange chamber 2. Subsequently, it can also be found in Figure 2 that an air inlet 5 communicating with the heat exchange chamber 2 is provided at the top of the housing 1, and at the same time, an air extraction pipe 6 is fixedly connected to the outer wall of the housing 1 above the partition 3. When the cooling tower unit operates, the cold air generated by the refrigeration assembly 4 is extracted through the air extraction pipe 6 and transported to the hydrogen breaking unit to cool the hydrogen breaking unit to prevent the hydrogen breaking unit from overheating. At the same time, during the air extraction process, the negative pressure generated inside the heat exchange chamber 2 can suck the outside air into the heat exchange chamber 2 through the air inlet 5, enabling continuous generation of low-temperature cold air inside the heat exchange chamber 2 to continuously and stably provide low-temperature air for heat dissipation to the hydrogen breaking unit.
[0027] However, since the water carried in the outside air will become condensed water after being sucked into the heat exchange chamber 2 and cooled, and will adsorb on the inner wall of the heat exchange chamber 2 or the cold end of the refrigeration assembly 4. As the condensed water increases, more and more water will accumulate at the cold end of the heat exchange chamber 2. Therefore, by observing Figure 4It can be found that a through hole 7 is formed in the middle of the partition plate 3, and the top of the partition plate 3 is gradually inclined downward from the outside to the inside with the through hole 7 as the center to form a guiding surface 8 for guiding condensed water. At this time, the accumulated condensed water will flow downward through the through hole 7 until it converges at the hot end of the heat exchange chamber 2 to cool the hot end of the refrigeration component 4, so as to ensure the stable heat exchange between the cold end and the hot end of the refrigeration component 4, and further ensure that the cooling tower unit provides a stable heat dissipation effect for the hydrogen breaking unit.
[0028] In a further preferred embodiment of the present invention, as Figure 2 and Figure 3 shown, the refrigeration component 4 includes a compressor 41, an evaporator 42, a condenser 43 and a throttle valve 44. The compressor 41 is fixedly connected inside the partition plate 3. The top and bottom of the compressor 41 are respectively connected with the evaporator 42 and the condenser 43 through pipelines, and a throttle valve 44 is connected between the evaporator 42 and the condenser 43 through a pipeline;
[0029] A water supply pipe 9 for injecting cooling water is fixedly connected to the bottom of the outer wall of the housing 1, and an exhaust pipe 10 for discharging steam is fixedly connected above the water supply pipe 9 and below the partition plate 3 of the housing 1;
[0030] A blocking portion 11 is formed by a protrusion at a place of the through hole 7 at the bottom of the partition plate 3, and the bottom of the blocking portion 11 is lower than the exhaust pipe 10.
[0031] In this embodiment, by providing the compressor 41, the evaporator 42, the condenser 43 and the throttle valve 44, the compressor 41 sucks in low-temperature and low-pressure refrigerant vapor from the evaporator 42, adiabatically compresses it into high-temperature and high-pressure superheated vapor through the compressor 41, then presses it into the condenser 43 for constant-pressure cooling, and releases heat to the cooling medium. Then the superheated vapor is cooled into subcooled liquid refrigerant, and the liquid refrigerant adiabatically throttles into low-pressure liquid refrigerant through the throttle valve 44 and evaporates in the evaporator to absorb heat from the air, thereby cooling the air to achieve the purpose of refrigeration.
[0032] And observing Figure 2 it can be found that a water supply pipe 9 for injecting cold water is connected to the bottom of the outer wall of the housing 1, which can cool the condenser 43 to ensure the condensation effect of the condenser 43. And because the water will accelerate evaporation after absorbing heat and increasing in temperature, thereby generating high-temperature water vapor at the hot end of the heat exchange chamber 2, and in the hydrogen breaking process, the dehydrogenation treatment process needs to heat and dehydrogenate the material. Therefore, an exhaust pipe 10 for discharging steam is fixedly connected above the water supply pipe 9 and below the partition plate 3 of the housing 1, which can extract the hot steam accumulated above the hot end of the heat exchange chamber 2 for preheating the material, reducing the energy consumption of heating and dehydrogenating, and reducing the cost of hydrogen breaking.
[0033] Since hot steam will preferentially diffuse upward and there is a through hole 7 in the middle of the partition plate 3, it will cause the hot steam to enter the cold end and affect the refrigeration effect of the cold end. Therefore, in order to reduce the upward diffusion of hot air, the bottom of the partition plate 3 is convex downward at the position of the through hole 7 to form a blocking portion 11, and the bottom of the blocking portion 11 is lower than the exhaust pipe 10, so that water vapor can be preferentially accumulated above the blocking portion 11, and then the accumulated hot steam will be drawn away by the exhaust pipe 10, which can effectively reduce the influence of hot steam entering the cold end through the through hole 7 on the refrigeration of the cold end.
[0034] In a further preferred embodiment of the present invention, as Figure 4 shown, a limiting ring 12 is fixedly connected to the bottom of the through hole 7, a diaphragm 13 is hinged to the bottom of the limiting ring 12, and the diameter of the diaphragm 13 is larger than the inner hole diameter of the limiting ring 12;
[0035] A blocking block 14 for blocking the diaphragm 13 is fixedly connected to the inner wall of the through hole 7 below the limiting ring 12 away from the hinge position of the diaphragm 13.
[0036] In this embodiment, the blocking portion 11 provided can block the hot air from entering the cold end through the through hole 7 to a certain extent. At the same time, the exhaust pipe 10 can extract the accumulated hot steam to prevent the excessive accumulation of hot steam at the hot end of the heat exchange cavity 2 from being discharged through the through hole 7. However, once the exhaust of the exhaust pipe 10 is closed, or the generation rate of hot steam increases, resulting in the untimely discharge of hot steam, it will still cause hot steam to be discharged through the through hole 7. Therefore, observing Figure 4 it can be found that a limiting ring 12 is connected to the bottom of the through hole 7, a diaphragm 13 is hinged to one side of the bottom of the limiting ring 12, and the diameter of the diaphragm 13 is larger than the inner hole diameter of the limiting ring 12. When the hot steam at the hot end increases, the hot steam at the hot end enters the through hole 7 under the air pressure and flows upward, which will push the diaphragm 13 to block the inner hole of the limiting ring 12, thus achieving the effect of blocking steam leakage and effectively ensuring that the cold end will not be interfered by hot steam during refrigeration, thereby ensuring the stability of refrigeration.
[0037] Observing Figure 4 it can also be found that a blocking block 14 for blocking the diaphragm 13 is fixedly connected to the inner wall of the through hole 7 below the limiting ring 12 away from the hinge position of the diaphragm 13. When the air pressure at the hot end of the heat exchange cavity 2 returns to normal pressure and the diaphragm 13 droops and opens under the action of gravity, the diaphragm 13 will be blocked by the blocking block 14. While ensuring that the condensed water accumulated in the through hole 7 can flow into the hot end when the diaphragm 13 opens, it can avoid the situation that the opening amplitude of the diaphragm 13 is too large and affects the stable closing of the inner hole of the limiting ring 12 by the diaphragm 13 when the subsequent hot steam flows upward, thereby ensuring the stability of blocking steam.
[0038] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model shall be covered within the protection scope of the present utility model.
