Description

Technical Field

[0001] The invention belongs to the technical field of cooling towers, in particular to a cross-flow type water-saving and mist-eliminating 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

[0007] As a further improvement of the above technical solution: an outward convex structure is arranged on the folding surface to form an installation channel; and the hinge mechanism is arranged in the installation channel.

[0008] 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.

[0009] As a further improvement of the above technical solution: the air guide device includes a U-shaped frame and a vertically arranged mounting shaft; an air guide plate is arranged on the mounting shaft; the two end heads of the U-shaped frame are respectively hinged to the corresponding air guide plates; a sliding shaft is arranged at the tail of the U-shaped frame, the sliding shaft passes through the sliding hole on the mounting rod, and a pulley is arranged at the tail end of the sliding shaft; the upper and lower ends of the mounting rod and the mounting shaft are connected to the tower body; an extrusion block for driving the sliding shaft to move is arranged on the connecting rod.

[0010] As a further improvement of the above technical solution: the U-shaped frame is an elastic bracket.

[0011] As a further improvement of the above technical solution: the extrusion block is provided with an inclined surface, and the pulley moves on the inclined surface.

[0012] As a further improvement of the above technical solution: the inclined surface is located on the outer side of the extrusion block; and a spring is arranged on the sliding shaft.

[0013] As a further improvement of the above technical solution: the extrusion block is hook-shaped; the inclined surface is located on the inner side of the hook of the extrusion block.

[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 hinge mechanism adopted by the present invention can conveniently control the opening and closing degree of the folding 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 be operated 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, so that the folded filler sheets that are attached together are squeezed and separated. The 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 induced wind action of the fan, the dry and cold airflow in the external environment passes through and enters the interior of the cooling tower. In the process of passing through, it exchanges heat with the spray water on the other side of the filler with the filler sheet as the medium, and then exchanges heat with the humid and hot airflow in the water-free area on the other side with the filler sheet as the medium, and then enters the tower body through the filler channel. When the temperature rises, the absolute humidity remains unchanged. At this time, the airflow on the other side of the filler comes into direct contact with water, and the temperature and humidity increase. Now it exchanges heat with the dry and low-temperature air on the other side with the filler as the medium. Part of the moisture is condensed and then flows out of the filler. The two gases meet and mix after leaving the filler. We can understand that the airflow after leaving the filler of a 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 water content per unit volume of the saturated hot airflow and reducing the relative humidity. In addition, part of the moisture is condensed in the process of the hot and humid airflow flowing out of the filler, so that the cooling tower can achieve the effect of water saving and defog.

[0018] The opening and closing mechanism used in the present technical solution, in addition to achieving the demisting effect through cooling, can also be adjusted according to different environmental working conditions. By adjusting the opening and closing degree of the filler, the amount of airflow in contact with water and the amount of airflow not in contact with water is adjusted, which is more advantageous than other technologies.

[0019] 3. The air guide 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.

[0020] 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

[0039] 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.

[0040] like Figure 1-16 As shown, as a preferred embodiment of the present invention, a cross-flow water-saving and mist-eliminating cooling tower comprises fillers 3 arranged at intervals below a water-spreading basin 2, and the gaps between adjacent fillers 3 constitute a moist and hot air flow channel 34; the width of the fillers 3 is greater than the width of the water-spreading basin 2; each piece of filler 3 is folded in half to form an inverted U-shape, and the folded surfaces overlap and fit each other; a hinge mechanism 4 for controlling the opening of the folded surfaces is installed between the folded surfaces; the folded surfaces are opened to form a dry and cold air flow channel 35; the hinge mechanism 4 comprises a first hinge 42 and a second hinge 43 distributed on both sides; the upper ends of the first hinge 42 and the second hinge 43 are hinged to the upper mounting shaft 41, and the lower ends are hinged to the lower mounting shaft 44; both ends of the upper mounting shaft 41 are connected to the fixing rod 6; both ends of the lower mounting shaft 44 are connected to the connecting rod 10; and both ends of the connecting rod 10 are connected to the lifting drive mechanism 5.

[0041] Usually, each packing 3 is installed at intervals of 18-40mm on the air inlet side of the cooling tower. The width of the packing 3 is greater than the width of the water basin 2, and the excess portion generally ranges from 500mm to 1000mm. The portion of the packing that exceeds the width of the water basin is in the inner direction of the cooling tower.

[0042] 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. No less than two hinge mechanisms 4 are arranged on each piece of filler 3 to ensure the stability of the dry and cold air flow channel formed after the folded surface of the filler 3 is opened.

[0043] Further optimization based on the above embodiment: the lifting drive mechanism 5 is an electric push rod or a cylinder or an oil cylinder or a screw mechanism. Figure 2 As shown, the electric push rod is vertically installed on the outer wall of the tower body 1. When the electric push rod is extended or retracted, it drives the connecting rod 10 to move up and down.

[0044] Further optimization is made on the basis of the above embodiment: the folding surface is provided with an outer convex structure 31 to form a mounting channel 32; the hinge mechanism 4 is arranged in the mounting channel 32. Figure 4-5 As shown, the two folded surfaces of the filler 3 are symmetrically provided with convex structures 31, so that an installation channel 32 is formed between the folded surfaces, and the hinge mechanism 4 is inserted into the installation channel 32. When the hinge mechanism 4 is folded, it is ensured that the two folded surfaces are fitted together; when the hinge mechanism 4 is opened, the two folded surfaces are opened to form a dry cold air flow channel.

[0045] Further optimization is made on the basis of the above embodiment: the outlet direction of the hot and humid air flow channel 34 is provided with an air guide device 7 which automatically opens and closes as the width of the dry and cold air flow channel 35 changes; the opening and closing degree of the air guide device 7 is controlled by the movement of the connecting rod 10. The air guide device 7 is used to guide the hot and humid air flow coming out of the hot and humid air flow channel 34, and guide the hot and humid air flow to collide and mix with the dry and cold air flow. The connecting rod 10 can control the opening angle of the air guide device 7 and the opening width of the folded surface of the filler at the same time.

[0046] The above embodiment is further optimized: the air guide device 7 includes a U-shaped frame 73 and a vertically arranged mounting shaft 72; an air guide plate 71 is arranged on the mounting shaft 72; the two end heads of the U-shaped frame 73 are respectively hinged to the corresponding air guide plates 71; a sliding shaft 74 is arranged at the tail of the U-shaped frame 73, the sliding shaft 74 passes through the sliding hole on the mounting rod 9, and a pulley 76 is arranged at the tail end of the sliding shaft 74; the upper and lower ends of the mounting rod 9 and the mounting shaft 72 are connected to the tower body 1; the connecting rod 10 is provided with an extrusion block 8 for driving the sliding shaft 74 to move.

[0047] like Figure 9-16As shown, the mounting shaft 72 is vertically mounted in the air outlet direction of the moist and hot air flow channel 34, and two air guide plates 71 are hingedly arranged on the same mounting shaft 72; or two mounting shafts 72 are vertically arranged in the air outlet direction of each moist and hot air flow channel 34, and an air guide plate 71 is hingedly arranged on each mounting shaft 72; the two ends of the U-shaped frame 73 are hingedly connected to the outer walls of the corresponding air guide plates 71; when the U-shaped frame 73 moves forward and backward, the two air guide plates 71 are driven to open and close; the sliding shaft 74 at the rear end of the U-shaped frame 73 is inserted into the sliding hole on the mounting rod 9, and the upper and lower ends of the mounting rod 9 are fixed to the tower body 1; the connecting rod 10 is evenly installed with extrusion blocks 8, and the number of extrusion blocks 8 is consistent with the number of air guide devices 7.

[0048] Further optimization based on the above embodiment: the U-shaped frame 73 is an elastic frame. The U-shaped frame 73 is made of elastic material, so that the two ends of the U-shaped frame 73 can be reset after opening, ensuring that the two air guide plates 71 can be stably opened and closed.

[0049] Further optimization is made based on the above embodiment: the extrusion block 8 is provided with an inclined surface 77, and the pulley 76 moves on the inclined surface 77. Figure 9-16 As shown, the up and down lifting movement of the inclined surface 77 pushes the pulley 76 to move forward and backward in the horizontal plane, thereby driving the U-shaped frame 73 to move forward and backward in the horizontal plane, thereby driving the two air guide plates 71 to open and close.

[0050] The above embodiment is further optimized as follows: the inclined surface 77 is located on the outer side of the extrusion block 8 ; and a spring 78 is provided on the sliding shaft 74 .

[0051] like Fig.15 As shown, an embodiment of the wind guide device 7 is shown. When the connecting rod 10 is in a descending state, the pulley 76 is squeezed by the squeezing block 8, pushing the sliding shaft 74 forward, thereby driving the two wind guide plates to retract.

[0052] like Fig.16 As shown, when the connecting rod 10 rises, the extrusion block 8 rises, the sliding shaft 74 moves backward under the elastic force of the spring 78, and the U-shaped frame 73 pulls the two air guide plates 71 to open.

[0053] The above embodiment is further optimized as follows: the extrusion block 8 is hook-shaped; the inclined surface 77 is located on the inner side of the hook of the extrusion block 8 .

[0054] like Figure 10-14 As shown, another embodiment of the wind guide device is shown. When the connecting rod 10 is in a descending state, the extrusion block 8 descends, and the pulley 76 moves forward on the inclined surface 77, so that the sliding shaft 74 moves forward, and the U-shaped frame 73 pushes the two wind guide plates to close.

[0055] When the connecting rod 10 rises, the extrusion block 8 rises, and the pulley 76 moves due to the extrusion force of the inclined surface 77, so that the sliding shaft 74 moves backward, and the U-shaped frame 73 pulls the two air guide plates to open.

[0056] Further optimization based on the above embodiment: the filler 3 is provided with a protrusion 33 facing the direction of the moist and hot air flow channel 34; the protrusions 33 on both sides of the moist and hot air flow channel 34 are staggered with each other up and down; the upper side surface of the protrusion 33 is an inclined surface or an arc concave surface.

[0057] The protrusion 33 allows the hot and humid water flow entering the hot and humid air flow channel 34 to automatically jump onto the opposite filler sheet when flowing downward along the filler 3. Therefore, the hot and humid water flow bounces back and forth on the filler sheet in the hot and humid air flow channel 34, thereby improving the cooling effect of the hot and humid water flow.

[0058] The specific working principle of the present invention is:

[0059] Through the special design of the cooling filler, the filler can be folded and overlapped, and the filler width used in this technology is much larger than the width of the water basin, that is, when the cooling tower is running, there is always a part of the filler that exceeds the water spraying range. During installation, the folded edge of the filler is on the top, and the part of the filler that exceeds the width of the water basin is in the direction of the inside of the cooling tower.

[0060] The product of the present invention is designed with a hinge mechanism, which can be controlled to open or close the folded and overlapped fillers as required. When the winter operation mode is required to eliminate fog and save water, the hinge mechanism is controlled to open. Because 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 overlapped fillers are opened, the dry and cold airflow of the external environment passes through the opened channel without contacting the spray water of the cooling tower. However, the airflow uses the filler sheet as a medium to successively exchange heat with the spray water and the humid and hot airflow on the other side. The temperature of the airflow rises during this process, and the absolute humidity does not change. Because the width of the filler is greater than the width of the water-spreading basin, the airflow in contact with the spray water passes through the water-spreading basin. When it is still in the filler area, it exchanges heat with the airflow on the other side using the filler as a medium. The humid and hot airflow is cooled and condensed, thereby achieving the effect of eliminating fog and saving water. The two airflows meet after flowing out through the filler and then mix. The relative humidity and absolute humidity of the mixed airflow are lower than those of the humid and hot airflow, thereby achieving the effect of eliminating fog.

[0061] Demisting mode: the lower mounting shaft 44 is controlled to rise by the lifting drive mechanism 5, so that the first hinge 42 and the second hinge 43 are respectively convex to both sides, so that the two folded surfaces of each filler 3 are opened 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 air flow and the humid hot air flow in the adjacent humid hot air flow channel 34 perform heat exchange with the filler 3 as the medium, thereby reducing the relative humidity and achieving the purpose of demisting.

[0062] The two folded surfaces open to both sides at the same time, so that the moist and 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.

[0063] like Fig.17 As shown, airflow 151 is the state of dry cold air from the outside, airflow 222 is the state of dry cold air from the outside after passing through the water channel of the filler and being in the area with spray water below the water-spreading basin. It can be seen from the figure that it is close to 100% saturated. Airflow 192 is the state of dry cold air from the outside after passing through the waterless channel of the filler and being in the area below the water-spreading basin. In the process of passing through the waterless channel of the filler and being in the area below the water-spreading basin, heat exchange occurs in the dry cold air, the temperature rises, the absolute humidity remains unchanged, and the relative temperature decreases. When airflow 222 passes through the area outside the water-spreading basin, airflow 192 also passes through the area outside the water-spreading basin. In the process of passing through this area, the two airflows exchange heat with the filler as the medium. After passing through, airflow 222 becomes airflow 233, and after passing through, airflow 192 becomes airflow 203. Airflow 233 and airflow 203 are mixed into airflow 244 inside the cooling tower. Airflow 244 is discharged from the cooling tower and meets the dry cold airflow 151 from the outside, and is mixed into airflow 255. In this process, when airflow 222 changes to state 233, condensation occurs, achieving the effect of water saving. Airflow 244 is in a non-saturated state, and its temperature, relative humidity, and absolute temperature are all lower than airflows 222 and 233. When mixed with the dry and cold air outside, it will not reach a saturated state, thereby achieving the purpose of defogging.

[0064] Adjustment of demisting effect: The lifting distance of the lower mounting shaft 44 is controlled by the lifting drive mechanism 5, 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.

[0065] Alternating operation of defogger and non-defogger: the lifting drive mechanism 5 is continuously moved up and down, so that the dry cold air flow channel 35 is continuously opened and closed.

[0066] Non-defog mode: the lower mounting shaft 44 is controlled to descend by the lifting drive mechanism 5, so that the first hinge 42 and the second hinge 43 are retracted toward the middle, 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 weight of the water film, the filler is pulled downward and remains vertical, and the two folded surfaces of the filler are attached together.

[0067] 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. The opening degree of the air guide plate can change with the up and down movement height 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.
