Description

Technical Field

[0001] The invention belongs to the technical field of cooling towers, in particular to a cross-flow type mist elimination cooling tower. Background Art

[0002] When the cooling tower is in operation, the air entering the cooling tower exchanges heat and moisture with the cooling water in the tower, the temperature of the cooling water decreases, and some water is lost due to evaporation; the air temperature rises and absorbs the evaporated water vapor, reaching or approaching saturation, and is discharged into the air. This phenomenon is most obvious in winter, and the cooling tower has plume fog. The plume fog phenomenon interferes with human life, such as the surrounding environment being shrouded in smog, the surrounding ground freezing, and the humidity of the surrounding air. As a general civilian cooling tower, the cross-flow cooling tower is widely used in residential communities, hospitals, hotels, shopping malls, etc. Relatively speaking, it is a type of cooling tower that is closer to people's lives. Any little progress in environmental improvement is very important to people's lives.

[0003] The "Acceptance Test Procedure for Defogging and Water-Saving Cooling Towers" issued by the China Engineering Construction Association in 2018 stipulates that the qualified standard for the air mixing coefficient out of the tower is not less than 85%. Among the current cross-flow cooling tower products, in order to achieve the defogging function, the structure is relatively complex and the cost is high compared to ordinary cooling towers. Therefore, it does not have good competitiveness in the market competition, which seriously hinders the development of the industry. Summary of the invention

[0004] In view of the above problems, the present invention provides a cross-flow demisting cooling tower, which can eliminate the plume phenomenon occurring when the cooling tower is operating in a low-temperature environment. Compared with various existing technical solutions, the technical measures adopted by the present invention are easier to implement, have lower costs, are flexible to adjust, and have good demisting effects.

[0005] A cross-flow mist-eliminating cooling tower comprises fillers arranged at intervals on the air inlet side of a tower body, wherein the gaps between adjacent fillers form a moist and hot air flow channel; each piece of filler is folded in half to form an inverted U-shape, and the two folded surfaces of each piece of filler overlap and fit each other; a plurality of convex structures are arranged on the inner sides of the two folded surfaces of each piece of filler to form an installation channel; a filler opening and closing mechanism for controlling the opening of the folded surfaces of the filler is installed in the installation channel; the two folded surfaces of the filler are opened to form a dry and cold air flow channel.

[0006] As a further improvement of the above technical solution: the upper end of the filler is mounted on the filler opening and closing mechanism or on the crossbeam.

[0007] As a further improvement of the above technical solution: the filler opening and closing mechanism is a sheet hinge mechanism; the sheet hinge mechanism includes an upper hinge and a lower hinge hinged to each other; both ends of the upper hinge are connected to a fixed rod; the fixed rod is installed on the tower body; both ends of the lower hinge are provided with extension shafts; the extension shaft is rotatably installed in a hole opened on the connecting rod; the connecting rod is connected to the driving mechanism.

[0008] As a further improvement of the above technical solution: the driving mechanism is a linear reciprocating motion mechanism.

[0009] As a further improvement of the above technical solution: the driving mechanism includes a rocker arm hinged to the connecting rod; the rocker arm is connected to the motor.

[0010] As a further improvement of the above technical solution: the cross section of the lower hinge is T-shaped.

[0011] As a further improvement of the above technical solution: the hole spacing between the holes on the connecting rod is consistent with the spacing distance of each filler.

[0012] As a further improvement of the above technical solution: an air guide device is provided at the air outlet direction of the hot and humid air flow channel, which automatically opens and closes as the width of the dry and cold air flow channel changes; the opening and closing degree of the air guide device is controlled by the movement of the connecting rod.

[0013] As a further improvement of the above technical solution: the air guide device includes two rotating shafts arranged vertically side by side, and air guide plates are installed on the rotating shafts; gears are provided at the ends of the rotating shafts or the ends of the air guide plates; the gears are meshed with each other; a movable hole is provided at the rear end of one of the air guide plates; and the movable hole is sleeved on the corresponding drive shaft on the connecting rod.

[0014] As a further improvement of the above technical solution: the filler is provided with protrusions facing the direction of the moist and hot air flow channel; the protrusions on both sides of the moist and hot air flow channel are arranged alternately up and down; the upper side surface of the protrusion is an inclined surface or an arc concave surface.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] 1. In the technical measures adopted by the present invention, the low-humidity airflow and the high-humidity airflow meet and mix in the tower in the form of thin sheets, and the uniformity of the infiltration and mixing of the two airflows is more excellent. The filler control opening and closing mechanism adopted by the present invention can conveniently control the opening and closing degree of the folded filler according to different working conditions. The structure is simple and easy to implement. The product involved in the present invention has low cost and is more competitive in the market.

[0017] 2. According to the operating environment and requirements of the cooling tower, in winter, the cooling tower needs to operate in defogging mode. By controlling the rotation of the servo motor, the lower hinge of the hinge mechanism before the large folded filler sheet is rotated under the drive of the connecting rod mechanism, thereby squeezing the folded surfaces of the filler that are bonded together apart. The dry and cold air flow channel formed after separation is closed at the top, and the spray water of the cooling tower will not enter this channel. Under the action of the fan's induced wind, the dry and cold air flow in the external environment passes through and enters the interior of the cooling tower. In the process of passing through, heat is exchanged with the spray water on the other side of the filler using the filler sheet as the medium. When the air exits the filler channel and enters the interior of the tower, the temperature rises while the absolute humidity remains unchanged. At this time, the air flow on the other side of the filler is in direct contact with water, and the temperature and humidity increase. It can be understood that it is saturated hot and humid air when it exits the filler channel and enters the interior of the tower. The two streams of air meet and mix after leaving the filler. We can understand that the airflow after leaving the filler of the non-defog cooling tower is a saturated hot airflow with high absolute humidity and high relative humidity. At this time, another airflow with absolute humidity and relative humidity far lower than this is introduced, thereby diluting the unit volume water content of the saturated hot airflow and reducing the relative humidity, so that the cooling tower can achieve the effect of defog. The opening and closing mechanism used in this technical solution, in addition to achieving the effect of water-saving and defog, can also be adjusted according to different environmental conditions. It can adjust the opening and closing degree of the filler, and then adjust the amount of airflow in contact with water and the amount of airflow not in contact with water, which is more superior than other technologies.

[0018] 3. The air guide plate device corresponding to the outlet direction of the hot and humid air channel forms a V-shaped air guide plate after opening, which can make the hot and humid air in the hot and humid air channel flow to both sides and mix with the dry and cold air faster, thereby improving the mixing uniformity, further reducing the relative humidity, and improving the defogging effect. And the opening degree of the air guide plate can change with the moving distance of the connecting rod. As the width of the dry and cold air flow channel increases, the opening degree of the air guide plate automatically increases. As the width of the dry and cold air flow channel narrows, the opening degree of the air guide plate automatically decreases, realizing automatic and appropriate diversion of the hot and humid air to ensure the best defogging effect. When the dry and cold air channel is closed, the air guide plate is retracted, which will not affect the ventilation volume under non-defogging conditions.

[0019] 4. In the normal operation of the cooling tower in summer, the servo motor is adjusted to make the folded blades inserted between the folded filler sheets in a vertical state, and no squeezing pressure is applied to the fillers on the left and right sides. When the cooling tower is running, spray water forms a water film on the outer side of the folded filler. Under the action of the weight of the water film, the filler is pulled downward and remains vertical, and the two folded surfaces of the filler are attached together. This is the normal cooling tower working condition. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0039] Embodiment 1:

[0040] See also Figures 1 to 16 In a specific embodiment, a cross-flow demisting cooling tower includes fillers 3 arranged at intervals on the air inlet side of a tower body 1, and the gaps between adjacent fillers 3 form a moist hot air flow channel 34; each piece of filler 3 is folded in half to form an inverted U shape, and the two folded surfaces of each piece of filler 3 overlap and fit each other; a plurality of convex structures 31 are provided on the inner sides of the two folded surfaces of each piece of filler 3 to form an installation channel 32; a filler opening and closing mechanism for controlling the opening of the folded surfaces of the filler 3 is installed in the installation channel 32; the two folded surfaces of the filler 3 are opened to form a dry cold air flow channel 35.

[0041] Usually, each filler 3 is arranged and installed at intervals of 18-40 mm on the air inlet surface of the cooling tower, wherein the fillers 3 are distributed on both sides of the tower body 1, a water-spreading basin 2 is arranged above the fillers 3, a water-collecting basin 11 is arranged at the bottom of the tower body 1, and the fillers 3 are located below the water-spreading basin 2. The spray water in the water-spreading basin 2 is evenly sprayed onto the top of the fillers 3 through the nozzle, and then enters the wet and hot air flow channel 34, cools on the fillers 3, and then flows into the water-collecting basin 11. Each filler 3 is provided with no less than 2 installation channels 32, and each filler 3 is provided with no less than 2 filler opening and closing mechanisms to ensure the stability of the dry and cold air flow channel formed after the folded surface of the filler 3 is opened.

[0042] Embodiment 2:

[0043] Further optimization is performed on the basis of the above embodiment: the upper end of the filler 3 is mounted on the filler opening and closing mechanism or on the crossbeam 9 .

[0044] like Figure 7-8 As shown, the packing opening and closing mechanism is a sheet hinge mechanism 4 , and the upper end of the packing 3 is directly mounted on the upper hinge 41 of the sheet hinge mechanism 4 .

[0045] like Fig.11 As shown, the filler 3 is mounted on the cross beam 9. Both ends of the cross beam 9 are fixedly mounted on the tower body 1.

[0046] Implementation three:

[0047] Further optimization is performed on the basis of the above embodiment: the filler opening and closing mechanism is a sheet hinge mechanism 4; the sheet hinge mechanism 4 includes an upper hinge 41 and a lower hinge 42 hinged to each other; both ends of the upper hinge 41 are connected to a fixing rod 6; the fixing rod 6 is installed on the tower body 1; extension shafts 43 are provided at both ends of the lower hinge 42; the extension shaft 43 is rotatably installed in a hole opened on the connecting rod 10; the connecting rod 10 is connected to the driving mechanism 5.

[0048] like Figure 7-8 As shown, the upper hinge 41 is in the shape of a long plate, and the lower hinge 42 is in the shape of a long plate; the driving mechanism 5 drives the connecting rod 10 to move back and forth axially, thereby driving the lower hinge 42 to swing, so that the lower hinge 42 squeezes the filler 3 to make the folded surfaces of the filler 3 open to each other.

[0049] Implementation Four:

[0050] Further optimization based on the above embodiment: the driving mechanism 5 is a linear reciprocating motion mechanism. The driving mechanism 5 can be a cylinder or an electric push rod.

[0051] Embodiment five:

[0052] like Figure 2 As shown, the above embodiment is further optimized: the driving mechanism 5 includes a rocker arm 53 hinged to the connecting rod 10; the rocker arm 53 is connected to the motor 51. The motor 51 drives the rocker arm 53 to swing, and the rocker arm 53 drives the connecting rod 10 to move. The motor 51 is installed on the tower body 1.

[0053] Embodiment six:

[0054] like Figure 9-10 As shown, based on the above embodiment, the cross section of the lower hinge 42 is T-shaped. After the lower hinge 42 adopts the T-shaped structure, when the lower hinge 42 rotates, the two folded surfaces of the filler 3 will be driven to open to both sides at the same time, so that the wet hot air flow channel forms a structure that is wide at the top and narrow at the bottom. Therefore, when the spray water flows downward along the surface of the filler, the flow rate will be relatively slow, thereby extending the heat exchange time between the spray water and the filler sheet, improving the cooling effect, and further improving the defogging effect.

[0055] Embodiment seven:

[0056] Based on the above embodiment, further optimization is performed: the hole spacing between the holes on the connecting rod 10 is consistent with the spacing distance of each filler 3, so that the connecting rod 10 ensures that the opening and closing width of each filler 3 is stable and consistent during the movement.

[0057] Embodiment eight:

[0058] like Figure 13-16 As shown, it is further optimized on the basis of the above embodiment: the air outlet direction of the hot and humid air flow channel 34 is provided with an air guide device 7 that automatically opens and closes as the width of the dry and cold air flow channel 35 changes; the air guide device 7 controls the opening and closing degree by moving the connecting rod 10. The air outlet direction of each hot and humid air flow channel 34 is provided with an air guide device 7, which is two blades that can be opened and closed, and the opening and closing degree of the blades changes as the width of the dry and cold air flow channel 35 changes. When the dry and cold air flow channel 35 is closed, the air guide device 7 is also closed, which does not affect the circulation of the hot and humid air flow channel 34. When the dry and cold air flow channel 35 is gradually opened, the air guide device 7 is also gradually opened in a V shape, thereby guiding the hot and humid air flow in the hot and humid air flow channel 34 to both sides, and producing a faster mixing with the dry and cold air flow, thereby improving the mixing uniformity.

[0059] Embodiment nine:

[0060] like Figure 13-16 As shown, it is further optimized on the basis of the above embodiment: the air guide device 7 includes two rotating shafts 74 arranged vertically side by side, and an air guide plate 71 is installed on the rotating shaft 74; a gear 73 is provided at the end of the rotating shaft 74 or the end of the air guide plate 71; the gears 73 are meshed with each other; a movable hole 75 is provided at the rear end of one of the air guide plates 71; the movable hole 75 is sleeved on the corresponding drive shaft 8 on the connecting rod 10.

[0061] One structure of the wind guide device 7 is: the upper and lower ends of the rotating shaft 74 are rotatably installed on the tower body 1; the two rotating shafts 74 are installed close to each other and parallel; the upper and lower ends of the rotating shaft 74 are coaxially installed with gears 73, and the two gears 73 are meshed with each other, so that the two rotating shafts 74 rotate relatively synchronously; the wind guide plate 71 is fixedly installed on the rotating shaft 74.

[0062] Another structure of the air guide device 7 is: the upper and lower ends of the rotating shaft 74 are fixedly mounted on the tower body 1, the air guide plate 71 is rotatably sleeved on the rotating shaft 74, and the upper and lower ends of the air guide plate 71 are provided with gears 73, and the two gears 73 are meshed with each other.

[0063] The movable hole 75 is a waist-shaped hole. A vertical drive shaft 8 is evenly distributed on the bottom surface of the connecting rod 10, and the drive shaft 8 can be a pin; the drive shaft 8 is inserted into the corresponding movable hole 75; when the connecting rod 10 moves, the drive shaft 8 drives the air guide plate 71 to swing.

[0064] Embodiment ten:

[0065] like Fig.12 As shown, the above embodiment is further optimized: the filler 3 is provided with protrusions 33 facing the direction of the moist hot air flow channel 34; the protrusions 33 on both sides of the moist hot air flow channel 34 are arranged alternately up and down; the upper side surface of the protrusions 33 is an inclined surface or an arc concave surface. The protrusions 33 can make the moist hot water flow entering the moist hot air flow channel 34 automatically jump to the opposite filler sheet when flowing downward along the filler 3, so that the moist hot water flow in the moist hot air flow channel 34 reciprocates on the filler sheet, thereby improving the cooling effect of the moist hot water flow.

[0066] The specific working principle of the present invention is:

[0067] Through the special design of the cooling filler, the filler can be folded and overlapped. When installed, the folded edge of the filler is on the top. The product described in the present invention is also designed with a filler opening and closing mechanism, which can be controlled to open or close the folded and overlapping fillers as needed. When the defogging condition is required in winter, the filler opening and closing mechanism is controlled to open it. Since the folded edge is on the top, the circulating water sprayed above the filler will not flow to the inner side of the folded filler. Therefore, when the folded and overlapping filler is opened, the dry and cold airflow from the external environment passes through the channel formed by the opening without contacting the spray water of the cooling tower. However, the airflow exchanges heat with the spray water on the other side through the filler sheet. The temperature of the airflow rises during this process, and the absolute humidity does not change. Because there is no spray water above the part of the filler that exceeds the water-spraying basin, the airflow in contact with water becomes a nearly saturated hot and humid airflow through the area below the water-spraying basin, and then needs to pass through a filler area without spray water. In this process, the hot and humid airflow exchanges heat with the airflow on the other side of the filler that has not been in contact with water through the filler sheet as a medium, and the temperature of the hot and humid airflow decreases because it is nearly saturated. In the process of temperature reduction, water vapor is condensed, and the condensed water returns to the cooling tower, thereby achieving water saving in the cooling tower.

[0068] The temperature of the airflow in the waterless channel continues to rise, the relative humidity decreases, and the absolute humidity remains unchanged. After the two airflows pass through the cooling tower filler, they are mixed in the cooling tower. The temperature, relative humidity, and absolute temperature of the mixed airflow are lower than those of the hot and humid airflow passing through the water channel, thereby achieving the purpose of defogging.

[0069] Defogging mode: the motor 51 controls the lower hinge 42 to tilt up, so that the two folded surfaces of each filler 3 open to form a dry cold air flow channel 35; the dry cold air in the external environment passes through and enters the interior of the cooling tower. In the process of passing through, the dry cold airflow exchanges heat with the hot water and the humid hot airflow in the adjacent humid hot air flow channel 34 with the filler 3 as the medium, so that its temperature increases and its relative humidity decreases. After passing through the filler area, it mixes with the adjacent nearly saturated humid hot airflow. The relative humidity of the mixed airflow is much lower than that of the nearly saturated airflow, thereby achieving the purpose of defogging.

[0070] like Fig.17 As shown, airflow 151 is the state of dry cold air from the outside, airflow 162 is the state of dry cold air from the outside after passing through the water channel of the filler. It can be seen from the figure that it is close to 100% saturated. Airflow 172 is the state of dry cold air from the outside after passing through the waterless channel of the filler. Heat exchange occurs in the process of dry cold air passing through the waterless channel of the filler, the temperature rises, the absolute humidity remains unchanged, and the relative temperature decreases. After passing through the filler area, the two airflows are mixed into 183 in the cooling tower. The temperature of airflow 183 decreases relative to that of airflow 162, and the temperature decreases. After airflow 183 is discharged from the cooling tower, it is mixed with dry cold air 151 from the outside to form airflow 194. Airflow 194 is in a non-saturated state and will not produce plume.

[0071] Adjustment of defogging effect: The tilting angle of the lower hinge 42 is controlled by the motor 51, thereby controlling the opening angle of the two folded surfaces of the filler 3, and further adjusting the amount of airflow in contact with water and the amount of airflow not in contact with water.

[0072] Alternating operation of defogger and non-defogger: continuously controlling the motor 51 to rotate, so that the lower hinge 42 swings back and forth, thereby making the dry cold air flow channel 35 open and close continuously.

[0073] Non-defog mode: The motor 51 controls the lower hinge 42 to swing, so that the folded surface of the filler 3 is in a closed state, and water is sprayed on the outer side of the folded filler to form a water film. Under the action of the water film, the filler is pulled downward and remains vertical, and the two folded surfaces of the filler are attached together.

[0074] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0075] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the methods and core ideas of the present invention. The above is only a preferred implementation of the present invention. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the present invention, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as the protection scope of the present invention.
