Dehumidifier for air conditioning

Abstract

The present invention relates to the technical field of air dehumidification, and specifically to a dehumidifier for air conditioning, comprising a shell and a dehumidification belt, wherein the dehumidification belt is installed in the shell by rotating around a horizontal axis, and the dehumidification belt is annular. When the dehumidification belt rotates, it passes through a first dehumidification zone, a drying zone, a cooling zone, and a second dehumidification zone in sequence in one cycle; the high-temperature dry gas entering the shell passes through the drying zone and then is discharged from the shell. When the dehumidification belt rotates to the drying zone, it is dried and heated under the action of the high-temperature dry gas, and when it rotates to the cooling zone, it is cooled to avoid excessive temperature when entering the second dehumidification zone, resulting in excessive temperature rise of the gas to be dehumidified. The gas to be dehumidified passes through the first dehumidification zone and the second dehumidification zone in sequence and then is discharged. The gas to be dehumidified can be dehumidified twice, thereby improving the dehumidification efficiency. At the same time, compared with a rotary dehumidification device, the humidity and temperature of the discharged gas are more uniform after the combined action of the first dehumidification zone and the second dehumidification zone.

Description

Technical Field

[0001] The invention relates to the technical field of air dehumidification, and in particular to a dehumidifier for air conditioning. Background Art

[0002] In humid areas or some processing workshops with high production environment requirements, it is necessary to dehumidify the air to keep the indoor humidity at an appropriate standard. Dehumidification devices are commonly used for dehumidification. The commonly used dehumidification device is a rotary dehumidifier, which realizes the alternating absorption and discharge of water vapor through the rotation of the wheel. That is, the dehumidification wheel is divided into a treatment area and a regeneration area. When the wheel rotates to the treatment area, it absorbs water vapor, and when it rotates to the regeneration area, it is dried and regenerated. Due to the structural limitations of the wheel, the transition area from the regeneration area to the treatment area is high in temperature, which easily causes the temperature of the dehumidified gas to rise. The transition area from the treatment area to the regeneration area has more water vapor adsorbed in the wheel, and the dehumidification effect is reduced, which easily causes the humidity of the dehumidified gas to increase. In summary, the rotary dehumidification device has the problem of uneven temperature and humidity of the gas after dehumidification. Summary of the invention

[0003] The invention provides a dehumidifier for air conditioning to solve the problem of uneven temperature and humidity of gas after dehumidification in the existing rotary dehumidification device.

[0004] An air conditioning dehumidifier of the present invention adopts the following technical solution:

[0005] A dehumidifier for air conditioning comprises a shell and a dehumidification belt; a partition is arranged in the shell, the partition is arranged horizontally and divides the shell into an upper chamber and a lower chamber, the dehumidification belt is installed in the shell by rotating around a horizontal axis, the dehumidification belt is annular, and the two sides of the dehumidification belt are arranged vertically and pass through the partition, the side of the dehumidification belt rotating from top to bottom is the first side, and the side of the dehumidification belt rotating from bottom to top is the second side; the area where the first side is located in the upper chamber is the first dehumidification zone, and the area where the first side is located in the lower chamber is the drying zone; the area where the second side is located in the upper chamber is the second dehumidification zone, and the area where the second side is located in the lower chamber is the cooling zone; the gas to be dehumidified entering the upper chamber of the shell passes through the first dehumidification zone and the second dehumidification zone and then is discharged from the shell; the high-temperature dry gas entering the lower chamber of the shell passes through the drying zone and then is discharged from the shell.

[0006] Furthermore, a first air inlet and a first air outlet are provided on the shell, and the first air inlet and the first air outlet are both connected to the outside of the shell and the upper chamber of the shell; the first air inlet is provided on the side wall of the shell close to the first dehumidification zone, and is used to allow the gas to be dehumidified to enter the upper chamber; the first air outlet is provided on the side wall of the shell close to the second dehumidification zone, and is used to allow the gas passing through the second dehumidification zone to discharge from the shell.

[0007] Furthermore, a second air inlet and a second air outlet are provided on the side wall of the shell, and the second air inlet and the second air outlet are both connected to the outside of the shell and the lower chamber of the shell; a guide pipe is provided in the shell, and the guide pipe connects the second air inlet and a side of the drying zone close to the cooling zone, and is used to guide the high-temperature dry gas to enter through the second air inlet, and flow through the drying zone of the dehumidification zone from the side of the dehumidification zone close to the cooling zone to the side away from the cooling zone; the second air outlet is provided on the side wall of the shell close to the drying zone, and is used to discharge the gas passing through the drying zone out of the shell.

[0008] Furthermore, three air guide covers are provided in the outer shell, namely a first air guide cover, a second air guide cover and a third air guide cover. The first air guide cover is provided in the upper chamber on the side close to the first air inlet, and limits the gas to be dehumidified entering from the first air inlet to pass only through the first dehumidification zone; the second air guide cover is provided in the upper chamber on the side close to the first air outlet, and limits the gas passing through the second dehumidification zone to be discharged only through the first air outlet; the second air guide cover is provided in the lower chamber on the side close to the second air outlet, and limits the high-temperature gas passing through the drying zone to be discharged only through the second air outlet.

[0009] Furthermore, two pulleys are rotatably installed in the shell, and the two pulleys are respectively located in the upper chamber and the lower chamber. The dehumidification belt is annular and is sleeved outside the two pulleys.

[0010] Furthermore, the dehumidification belt includes an annular belt and dehumidification particles fixed on the annular belt, and the annular belt is a hollow structure.

[0011] The beneficial effects of the present invention are as follows: the dehumidification belt of the air conditioning dehumidifier of the present invention passes through the first dehumidification zone, the drying zone, the cooling zone and the second dehumidification zone in sequence in one cycle when rotating. When the dehumidification belt rotates to the drying zone, it is dried and heated under the action of the high-temperature dry gas, and is cooled and cooled when rotating to the cooling zone, so as to avoid the temperature being too high when entering the second dehumidification zone, resulting in excessive temperature rise of the gas to be dehumidified. Furthermore, since the dehumidification belt is in a relatively dry state in the second dehumidification zone, the dehumidification effect is good and the temperature is higher than the temperature of the dehumidification belt in the first dehumidification zone. When the dehumidification belt rotates to the first dehumidification zone, the dehumidification belt has been dehumidified, and the dehumidification effect is reduced; the gas to be dehumidified is discharged after passing through the first dehumidification zone and the second dehumidification zone in sequence. The gas to be dehumidified can be dehumidified twice, thereby improving the dehumidification efficiency. At the same time, compared with the rotary dehumidification device, the exhaust gas has more uniform humidity and temperature after the combined action of the first dehumidification zone and the second dehumidification zone. In addition, the impurities adsorbed on the dehumidification belt will clump after drying in the drying zone, and some of them will be blown away by the high-temperature gas. The dehumidification belt is annular. When passing through the corner between the drying zone and the cooling zone, the dehumidification belt deforms, causing the impurities on the dehumidification belt to clump, crack and fall off, thus preventing the impurities from affecting the dehumidification effect of the dehumidification belt.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] An embodiment of an air conditioning dehumidifier of the present invention is as follows Figure 1 to Figure 2 As shown, it includes a shell 100 and a dehumidification belt 200. A partition 110 is arranged in the shell 100. The partition 110 is arranged horizontally and divides the shell 100 into an upper chamber and a lower chamber. The upper chamber is used to receive the gas to be dehumidified, and the lower chamber is used to receive high-temperature dry gas.

[0018] The dehumidification belt 200 is installed in the outer shell 100 and rotates around a horizontal axis. The dehumidification belt 200 is annular, and the two sides of the dehumidification belt 200 are vertically arranged and pass through the partition 110. The side of the dehumidification belt 200 that rotates from top to bottom is the first side, and the side of the dehumidification belt 200 that rotates from bottom to top is the second side; the area where the first side is located in the upper chamber is the first dehumidification zone, and the area where the first side is located in the lower chamber is the drying zone; the area where the second side is located in the upper chamber is the second dehumidification zone, and the area where the second side is located in the lower chamber is the cooling zone.

[0019] The gas to be dehumidified entering the upper chamber of the housing 100 passes through the first dehumidification zone and the second dehumidification zone and then is discharged from the housing 100; the high-temperature dry gas entering the lower chamber of the housing 100 passes through the drying zone and then is discharged from the housing 100.

[0020] When the dehumidification belt 200 rotates, it passes through the first dehumidification zone, the drying zone, the cooling zone and the second dehumidification zone in sequence in one cycle. When the dehumidification belt 200 rotates to the drying zone, it is dried and heated under the action of the high-temperature dry gas, and when it rotates to the cooling zone, it is cooled to avoid excessive temperature when entering the second dehumidification zone, which causes the temperature of the gas to be dehumidified to be too high. Furthermore, since the dehumidification belt 200 is in a relatively dry state in the second dehumidification zone, the dehumidification effect is good and the temperature is higher than the temperature of the dehumidification belt 200 in the first dehumidification zone. When the dehumidification belt 200 rotates to the first dehumidification zone, the dehumidification belt 200 has been dehumidified, and the dehumidification effect is reduced; the gas to be dehumidified is discharged after passing through the first dehumidification zone and the second dehumidification zone in sequence. The gas to be dehumidified can be dehumidified twice, which improves the dehumidification efficiency. At the same time, compared with the rotary dehumidification device, the exhaust gas has more uniform humidity and temperature after the combined action of the first dehumidification zone and the second dehumidification zone. In addition, impurities adsorbed on the dehumidification belt 200 clump together after being dried in the drying zone, and some of them will be blown away by the high-temperature gas. The dehumidification belt 200 is annular. When passing through the corner between the drying zone and the cooling zone, the dehumidification belt 200 deforms, causing the impurities on the dehumidification belt 200 to clump together, crack and fall off, thereby preventing the impurities from affecting the dehumidification effect of the dehumidification belt 200.

[0021] In this embodiment, the housing 100 is provided with a first air inlet 120 and a first air outlet 130, both of which are connected to the outside of the housing 100 and the upper chamber of the housing 100; the first air inlet 120 is provided on the side wall of the housing 100 close to the first dehumidification zone, and is used to allow the gas to be dehumidified to enter the upper chamber; the first air outlet 130 is provided on the side wall of the housing 100 close to the second dehumidification zone, and is used to allow the gas passing through the second dehumidification zone to be discharged from the housing 100. The first air inlet 120 is used to be connected to an external fan that supplies air to the housing 100, and the fan sends the external gas to be dehumidified into the upper chamber through the first air inlet 120.

[0022] In this embodiment, a second air inlet 140 and a second air outlet 150 are further provided on the side wall of the housing 100, and the second air inlet 140 and the second air outlet 150 are both connected to the outside of the housing 100 and the lower chamber of the housing 100; a guide pipe 160 is provided in the housing 100, and the guide pipe 160 is connected to the second air inlet 140 and the side of the drying zone close to the cooling zone, and is used to guide the high-temperature dry gas to enter through the second air inlet 140, and flow through the drying zone of the dehumidifying belt 200 from the side close to the cooling zone to the side away from the cooling zone; the second air outlet 150 is provided on the side wall of the housing 100 close to the drying zone, and is used to discharge the gas passing through the drying zone out of the housing 100. The second air inlet 140 is used to be externally connected to a hot air blower that feeds high-temperature dry gas into the housing 100, and the hot air blower feeds the heated dry gas into the lower chamber through the second air inlet 140.

[0023] In this embodiment, three air guide covers are further arranged in the housing 100, namely, the first air guide cover 170, the second air guide cover 180 and the third air guide cover 190. The first air guide cover 170 is arranged in the upper chamber near the first air inlet 120, and restricts the gas to be dehumidified entering from the first air inlet 120 to pass only from the first dehumidification zone; the second air guide cover 180 is arranged in the upper chamber near the first air outlet 130, and restricts the gas passing through the second dehumidification zone to be discharged only from the first air outlet 130; the second air guide cover 180 is arranged in the lower chamber near the second air outlet 150, and restricts the high-temperature gas passing through the drying zone to be discharged only from the second air outlet 150. Specifically, the first air guide cover 170, the second air guide cover 180 and the third air guide cover 190 are all in sliding sealing contact with the dehumidification belt 200.

[0024] In this embodiment, two pulleys 210 are rotatably installed in the outer shell 100, and the two pulleys 210 are respectively located in the upper chamber and the lower chamber. The dehumidification belt 200 is annular and is sleeved on the two pulleys 210; one of the pulleys 210 is externally connected to a driving motor, and the driving motor drives the pulley 210 to rotate, thereby driving the dehumidification belt 200 to rotate.

[0025] In this embodiment, the dehumidification belt 200 includes an annular belt and dehumidification particles fixed on the annular belt, and the annular belt is a hollow structure. The dehumidification particles are preferably made of silica gel material.

[0026] When the air conditioning dehumidifier of the present invention is in use, the external drive motor is started to drive one of the pulleys 210 to rotate, thereby driving the dehumidification belt 200 to rotate, so that the first side of the dehumidification belt 200 rotates from top to bottom, and the second side of the dehumidification belt 200 rotates from bottom to top, that is, when the dehumidification belt 200 rotates, a certain position of the dehumidification belt 200 passes through the first dehumidification zone, the drying zone, the cooling zone and the second dehumidification section in sequence and then returns to the first dehumidification zone. At the same time, the external fan and the hot air blower are started, and the dehumidified gas enters the upper chamber from the first air inlet 120, and passes through the first dehumidification zone and the second dehumidification zone of the dehumidification belt 200 in sequence and is discharged from the first air outlet 130. The high-temperature dry gas enters the lower chamber from the second air inlet 140, and flows from the side of the dehumidification belt 200 close to the cooling zone to the side away from the cooling zone, and is discharged from the second air outlet 150 after passing through the drying zone of the dehumidification belt 200, thereby drying the dehumidification belt 200 that rotates to the drying zone to ensure its dehumidification effect.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
