Description

Technical Field

[0001] The invention relates to the technical field of refrigeration equipment, and in particular to a high-efficiency temperature-reducing and dust-removing water curtain air cooler. Background Art

[0002] At present, the selection principle of traditional air coolers is that the temperature difference between the outlet temperature of the air cooler medium and the summer air design temperature must be greater than 15℃. At this time, the cost performance of the air cooler is the highest. If it is lower than 15 degrees or even the temperature between the two is close, when the air cooler is selected, the required heat exchange area will increase, the efficiency of the air cooler will decrease, and the cost will increase accordingly. Therefore, taking necessary summer measures to reduce the air inlet temperature of the air cooler and strengthen the cooling effect of the air cooler is one of the ways to solve the problem of the air cooler's summer output being blocked and improve the economy and safety of the air cooler.

[0003] Generally, the ambient air temperature is reduced by using a water curtain wall system, a circulating water system and a fan to increase the temperature difference between the outlet temperature of the air cooler medium and the summer air design temperature. However, the airflow that penetrates the water curtain wall for heat exchange will take away some water droplets and liquid beads from the water curtain wall. At the same time, the water vapor evaporation during the heat exchange process will make the consumption of the cooling liquid particularly fast. In addition, when the air cooler fan is running, dust and slag in the air will be adsorbed on the fins of the fan, affecting the heat exchange efficiency of the fan. At the same time, after long-term operation, the water curtain wall will retain the dust in the air in the pores for airflow to penetrate, causing pollution. Summary of the invention

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0024] Reference Figures 1 to 6 In some embodiments, a high-efficiency cooling and dust removal water curtain air cooler includes a frame 1, an axial flow fan 2, a water curtain wall structure, a water circulation structure, and a filter. An air outlet 101 is provided on the top of the frame 1, an air inlet net is provided on the side wall of the frame 1, and a water curtain wall structure for cooling the inflowing gas is provided at the air inlet net. A water circulation structure for circulating water to the water curtain wall structure is provided in the frame 1, and the axial flow fan 2 is provided in the frame 1. In some embodiments, according to the different ambient temperatures, there are two operating conditions: summer operating conditions and non-summer operating conditions. When the ambient temperature does not reach the design temperature, the equipment operates in a non-summer operating condition, and the air cooler operates normally. At this time, the axial flow fan 2 is started, and the rotation of the axial flow fan 2 drives the air flow, thereby cooling the inside of the frame 1. When the ambient temperature reaches the design temperature, the equipment operates in a non-summer operating condition. At this time, based on the operation of the axial flow fan 2, the circulating water system is started. At this time, the circulating water is injected from the water curtain wall structure, and the air flow is driven by the axial flow fan 2, so that the circulating water injected into the water curtain wall structure is atomized in the air, increasing the relative humidity of the air. This process is considered as isenthalpic humidification, thereby reducing the temperature of the air entering the air cooler, thereby achieving the purpose of cooling the inside of the frame 1, greatly improving the energy efficiency of the air cooler, and the un-atomized circulating water flows down through the water curtain wall structure and is recycled to the water circulation structure for further circulation, which can save resources. It can be understood that in some embodiments, the set temperature can be set to 15°C, and in some other embodiments, the set temperature is set as needed.

[0025] In some embodiments, the water curtain wall structure is embedded in part of the wall portions of two opposite side walls of the frame 1, and the water curtain wall structure includes a water curtain wall 31 arranged on the frame 1, a cache component 32 arranged opposite to the water curtain wall 31, and an extrusion component fitted with the cache component 32, the cache component 32 retains droplets carried away by the airflow from the water curtain wall 31, the extrusion component includes a rotating rod 331, a sponge roller 333 with a first sponge 332 wrapped around the outer wall, and a movable extrusion roller 334 arranged below the sponge roller 333, the axis of the rotating rod 331, the axis of the sponge roller 333 and the axis of the extrusion roller 334 are parallel, a guide plate 335 is vertically arranged below the extrusion roller 334, and the extrusion roller 334 is moved to squeeze the first sponge 332 and the cache component 32.

[0026] Specifically, Figures 2 to 5 As shown, the buffer element 32 includes a support plate 321 provided with a plurality of air holes 3211, and four mounting posts 322 are provided at the four corners of the support plate 321. The four mounting posts 322 are used to fit the second sponge 323 to the surface of the water curtain wall 31. The second sponges 323 are fixedly provided on both sides of the support plate 321. The second sponge 323 is provided with a plurality of protrusions matching the air holes 3211 on the end surface close to the support plate 321, and the size of the protrusions is smaller than the size of the air holes 3211. The airflow penetrating the water curtain wall 31 enters the second sponge 323 on one side close to the water curtain wall 31 and then reaches the second sponge 323 on the other side through the air holes 3211 on the support plate 321. In this process, the liquid droplets are absorbed by the second sponge 323, so as to achieve the purpose of retaining the liquid.

[0027] In some embodiments, columns 4 are provided on both sides of the water curtain wall 31, and rotating motors 5 are respectively provided on the two columns 4. The two ends of the rotating rod 331 are respectively connected to the two rotating motors 5, so that the rotating rod 331 and the two ends of the sponge roller 333 are concentrically arranged. A first gear 6 is provided on one side of the rotating rod 331, and the outer walls of the sponge roller 333 and the squeezing roller 334 are both in contact with the surface of the second sponge 323, and the sponge roller 333 is close to the top of the second sponge 323.

[0028] In some embodiments, the extrusion assembly also includes a longitudinal telescopic assembly and a support frame 7 respectively arranged on the inner sides of the two columns 4, and the support frame 7 is provided with a slide groove 71 running through the upper and lower parts. The longitudinal telescopic assembly includes a hydraulic cylinder 13 and a longitudinal telescopic rod 14. The hydraulic cylinder 13 is fixedly mounted on the upper surface of the bottom of the frame 1; the longitudinal telescopic rod 14 is connected to the output end of the hydraulic cylinder 13 and is located on the upper surface of the hydraulic cylinder 13.

[0029] In some embodiments, the extrusion assembly also includes an electric cylinder 15, a transverse telescopic rod 16, a connecting block 17, a fixed block 18, a connecting telescopic rod 19, a second gear 20 meshing with the first gear 6, an electric slider 21 and a connecting rod 22; the electric cylinder 15 is arranged on the side of the longitudinal telescopic rod 14 away from the hydraulic cylinder 13, the transverse telescopic rod 16 is connected to the output end of the electric cylinder 15, the connecting block 17 is rotatably connected to the second gear 20, and is fixedly installed on the end of the transverse telescopic rod 16 away from the electric cylinder 15, and the other side of the second gear 20 is connected to the connecting rod 22; the electric slider 21 is slidably connected in the slide groove 71, one end of the electric slider 21 is connected to the connecting telescopic rod 19, the end of the connecting telescopic rod 19 away from the electric slider 21 is connected to the fixed block 18, and the extrusion roller 334 is respectively connected to the connecting rod 22 and the fixed block 18.

[0030] During use, the second sponge 323 fits with the surface of the water curtain wall 31, and the second sponge 323 absorbs the droplets on the water curtain wall 31. When the second sponges 323 on both sides absorb the droplets to saturation, since the outer wall of the sponge roller 333 fits with the surface of one of the second sponges 323, the first sponge 332 on the sponge roller 333 absorbs the droplets on the second sponge 323. When the first sponge 332 absorbs the droplets to saturation, the hydraulic cylinder 13 is started, so that the power output from the output end of the hydraulic cylinder 13 drives the longitudinal telescopic rod 14 to extend and retract, thereby driving the electric cylinder 15 to move up and down, and then driving the squeezing roller 334 to move up and down, so as to adjust the height of the squeezing roller 334, and the fixing block 18 moves up and down, thereby driving the connecting telescopic rod 19 The electric slider 22 moves up and down, thereby driving the electric slider 22 to move up and down in the slide slot 71 of the support frame 7, so as to support the squeezing roller 334. By adjusting the height of the squeezing roller 334, the distance between the squeezing roller 334 and the sponge roller 333 can be adjusted, and the squeezing roller 334 fits the surface of the second sponge 323. When the squeezing roller 334 moves toward the direction close to the sponge roller 333, the squeezing roller 334 squeezes and squeezes out the water absorbed in the second sponge 323. When the squeezing roller 334 moves to collide with the sponge roller 323, the squeezing roller 334 squeezes and squeezes out the water absorbed in the first sponge 332. The squeezed water flows down along the squeezing roller 334 and the guide plate 335 under the action of gravity and is recycled. The second sponge 323 and the first sponge 332 can be repeatedly recycled to perform cyclic water retention and water absorption work, and the investment cost is low and the water retention efficiency is high. At the same time, by squeezing the squeezing roller 334 and the second sponge 323, the water in the second sponge 323 is squeezed out and poured into the plurality of air holes 3211 of the support plate 321, so as to flush and clean the dust trapped in the air holes 3211 and keep the air holes 3211 clean. In addition, a plurality of protrusions matching the air holes 3211 are arranged on the end surface of the second sponge 323 close to the support plate 321, and the size of the protrusions is smaller than the size of the air holes 3211. When the protrusions are inserted into the air holes 3211, when the second sponge 323 is squeezed, the protrusions guide the water squeezed out of the second sponge 323, and the air holes 3211 are thoroughly cleaned.Furthermore, the electric cylinder 15 is started, and the power output from the output end of the electric cylinder 15 drives the transverse telescopic rod 16 to extend and retract, thereby driving the connecting block 17 to move laterally, and then driving the second gear 20 to move laterally, so that the first gear 6 can mesh with the second gear 20 of corresponding size, and then the rotating motor 5 is started, and the power output from the output end of the rotating motor 5 drives the rotating rod 331 to rotate, thereby driving the sponge roller 333 and the first gear 6 to rotate, and the second gear 20 is driven to rotate by the rotation of the first gear 6, thereby driving the connecting rod 22 to rotate, and then driving the squeezing roller 334 to rotate, and the rotation of the sponge roller 333 and the squeezing roller 334 is combined to achieve comprehensive squeezing of the second sponge 323 and the first sponge 332, and can efficiently recover the moisture on the second sponge 323 and the first sponge 332 for recycling.

[0031] In some embodiments, a plurality of inverted conical collecting tips 3351 are disposed at the bottom of the guide plate 335, and the collecting tips 3351 are disposed in a continuous and progressive manner. The collecting tips 3351 further enhance the drainage function of the guide plate 335, and the water drained onto the guide plate 335 can be further gathered at each collecting tip 3351. Since the bottom of the collecting tip 3351 is pointed, the water gathered there is difficult to hang on it and drip. The water circulation structure includes a water storage tank, a circulation pump, a drainage trough 24 and a return water trough 25. The water storage tank and the circulation pump are both arranged inside the frame 1. The drainage trough 24 is arranged on the top of the water curtain wall 31. The drainage trough 24 is connected to the circulation pump through a pipeline. The return water trough 25 is arranged at the bottom of the water curtain wall 31. The return water trough 25 is connected to the water storage tank through a pipeline, and a water receiving trough 26 is arranged on the return water trough 25. The water receiving trough 26 is connected to the return water trough 25. The water receiving trough 26 is located directly below the collecting tip 3351, and is used to collect water squeezed out from the first sponge 332 and the second sponge 323, thereby saving cooling water.

[0032] In some embodiments, the high-efficiency cooling and dust removal air cooler further includes a dust removal mechanism, which includes a pipeline connected to the water tank 26, a water pump and a spray head 27, and the spray head 27 is arranged near the filter. The filter is arranged directly opposite the axial flow fan 2. By controlling the switch of the water pump to turn on the spray head 27, the water tank 26 supplies the spray head 27 to remove dust attached to the filter, thereby achieving the effect of dust removal.

[0033] like Figure 6As shown, in some embodiments, the high-efficiency cooling and dust removal air cooler also includes a replacement mechanism for replacing the first sponge 332, the replacement mechanism includes a pressure rod 91, two tensioning springs 92, a tensioning hook 93 and a fixing ring 94, the pressure rod 91 is parallel to the axis of the sponge roller 333 and applies pressure to the first sponge 332, one end of the two tensioning springs 92 is connected to both ends of the pressure rod 91, and the other end thereof is connected to the tensioning hook 93, the fixing ring 94 is fixedly set on the rotating rod 331, the tensioning hook 93 is movably passed through the fixing ring 94, and a limit buckle 95 is also arranged between the pressure rod 91 and the sponge roller 333, the limit buckle 95 is used to fix the first sponge 332 on the sponge roller 333.

[0034] When the first sponge 332 needs to be replaced, the tensioning hook 93 can be separated from the tensioning ring fixing ring 94, and the pressure rod 91 no longer applies pressure to the first sponge 332. At this time, the sheet-like first sponge 332 can be removed from the sponge roller 333, and a new sheet-like first sponge 332 is wound around the outer wall of the sponge roller 333. Then, the pressure rod 91 is pressed to the end of the first sponge 332 (there are two layers of first sponge 332 here), and the tensioning hook 93 is passed through the fixing ring 94. At this time, the tensioning spring 92 is in a stretched state, so that the pressure rod 91 applies pressure to the first sponge 332, and the first sponge 332 is wound around the outer wall of the sponge roller 333 under the action of this pressure (the side of the pressure rod 91 facing away from the sponge roller 333 is flush with or inside the outer side of the cylinder where the outer wall of the first sponge 332 is located, and will not protrude from the outer side of the cylinder where the outer wall of the first sponge 332 is located, and will not cause obstruction to the rotation of the sponge roller 333 which is closer to the squeezing roller 334).
