First embodiment
Referring to fig. 1-2, the present embodiment provides a paddle type adsorption air dryer, which includes a ventilation pipe 100, an isolation frame 200, a paddle 300, a protrusion 400, and a drain pipe 500. The ventilation pipe 100 includes a first outer frame 110 and a second outer frame 130, a separation frame 200 is disposed in the ventilation pipe 100, the separation frame 200 separates an air passage of the ventilation pipe 100 into an upper part and a lower part, wherein the separation frame 200 and the first outer frame 110 form an upper air passage 150, and the separation frame 200 and the second outer frame 130 form a lower air passage 170. The upper air duct 150 blows hot air from an upper air duct inlet 151, the hot air is generally from high temperature process air or air heated by a heating device, generally, the temperature of the hot air is preferably 80-120 ℃, and the hot air passes through the upper air duct 150 and is discharged from an upper air duct outlet 153. The lower duct 170 blows wet air from the lower duct air inlet 173, and the wet air is discharged from the lower duct air outlet 171 through the lower duct 170.
It should be noted that the structure of the ventilation pipe 100 may be different shapes, such as a circular pipe, a square, etc., and the ventilation pipe 100 may also be in the form of an integral body, a left-right structure, a multi-stage structure, etc. It is desirable to have a structure and form that can incorporate the necessary functional components to perform the drying function of the paddle type desiccant adsorbent and to perform the air drying process.
The isolation frame 200 is provided with a protrusion 400 at a position close to the upper duct inlet 151 on a side of the upper duct 150. It should be noted that the shape and size of the protrusion 400 are not limited, and the purpose is to guide the airflow in the upper air duct 150 near the side of the isolation frame 200 so that the portion of the airflow blows the paddle unit 300 to rotate at a proper angle and prevent the portion of the airflow from mixing with the airflow in the lower air duct 170 along the gap between the isolation frame 200 and the paddle unit 300.
The paddle machine 300 is disposed in the airway and includes a crankshaft 310 and paddles 330. Wherein the axis of the crankshaft 310 is perpendicular to the flow direction of the airflow in the air passage and is in the same plane as the isolation frame 200. The paddles 330 of the paddle machine 300 are partially in the upper airway 150 and partially in the lower airway 170. Generally, the number of blades 330 is at least two, with no upper limit. The paddle 330 comprises an outer frame 331, a mesh 333, and an adsorbent material 335. One of the frames of the outer frame 331 is connected to the shaft 310 and disposed on the outer circumferential surface of the shaft 310 in a fixed or detachable manner. The net structure 333 is disposed in the outer frame 331, and may be fixed or detachable. The materials of the outer frame 331 and the mesh structure 333 may be selected arbitrarily, in order to bear a certain centrifugal force and fix the adsorbing material 335 to complete the whole air drying process, in this embodiment, the outer frame 331 and the mesh structure 333 are made of stainless steel. The adsorbent material 335 is fixed in the mesh of the mesh structure 333.
The paddle 330 does not contact the first frame 110, the second frame 130, and the separation frame 200. Typically, the paddle 330 will be spaced a greater distance from the first frame 110 so that the reduced flow rate in the upper airway 150 at this point is sufficient for the adsorbent material 335 on the paddle 330 to function. Also, in order to enable the humid air to be sufficiently absorbed with moisture by the absorption material 335 and prevent the air in the lower duct 170 from being mixed with the air in the upper duct 150 through the gap more, the gap between the paddle 330 and the second outer frame 130 and the separation frame 200 is set relatively small. Of course, in order to further improve the air in the upper air duct 150 to fully react with the adsorbing material 335 on the blade 330, and to make the adsorbing material 335 on the blade 330 absorb the moisture of the humid air in the lower air duct 170, the positions of the first outer frame 110 and the second outer frame 130 on the blade unit 300 may be set to be arc-shaped, and the function of the arc-shaped is to reduce the flow rate of the air at the positions to fully react with the adsorbing material 335.
The second outer frame 130 is provided with a notch for connecting with the drain pipe 500. The drain duct 500 includes a drain spacer 510 and a drain port 530, the drain spacer 510 is disposed on the second frame 130 near the lower air duct intake 173 of the lower air duct 170, and the drain spacer 510 forms a drain passage 550 with the second frame 130. The drain port 530 is provided under the paddle unit 300 to collect dew-water drawn off by centrifugal action, and one end of the drain port 530 is connected to the notch of the second outer frame 130 and the other end is connected to the drain passage 550.
It should be noted that the form of the drain pipe 500 is various and the structure thereof may be changed, for example, it is possible to remove the drain partition 510 and to directly increase the structure of the second housing 130 at the position toward the lower air path intake 173 to facilitate the drainage of the water, and therefore, the structure and form of the drain pipe 500 are preferable as long as the collection and drainage of the water can be accomplished.
The embodiment also includes an air drying method, which comprises the following steps:
the wet air is blown into the lower air channel 173, the air flow drives the paddle 300 to rotate, and the dew entrained in the wet air is removed by the centrifugal force of the paddle 300 and flows into the drain pipe 500 through the drain port 530 to be discharged.
The wet air contacts the adsorbing material 335 of the paddle 330 in the lower air duct 170, the adsorbing material 335 absorbs moisture in the wet air, and the wet air is converted into dry air after being absorbed by the adsorbing material 335 and discharged from the lower air duct exhaust port 171.
Hot air is blown into the upper air duct inlet 151, when the adsorbing material 335 adsorbing moisture enters the upper air duct 150 from the lower air duct 170 under the driving of the paddle machine 300, because the adsorption pressure of the hot air in the upper air duct 150 is greater than that of the adsorbing material 335, the moisture in the adsorbing material 335 is removed by the hot air and is discharged and taken away by the hot air along the upper air duct exhaust port 153, at this time, the adsorbing material 335 recovers the adsorbability and is driven by the paddle machine 300 to enter the lower air duct 170 to absorb moisture in the humid air in the lower air duct 170 again. And at this point, the whole process is circulated to finish the drying of the air by the blade type adsorption air dryer.
The blade type adsorption air dryer provided by the embodiment has the advantages of simple structure, small volume and convenience in installation and movement. The requirements of different dryness can be met by adjusting the amount and the flow rate of the blown air flow, and the cost performance is high. The air inlet volume is big and the air inlet scope can adjust control as required. The humid air is firstly subjected to centrifugal action of the paddle machine 300 to remove dew entrained therein, then the moisture in the humid air is absorbed by the adsorbing material 335, finally the moisture in the adsorbing material is removed in the hot air to restore the adsorbability, and through two different modes, the drying effect can reach a higher degree and the adsorbing material 335 can keep stronger adsorbability. The rotation of paddle machine 300 drives the rotation and realizes the circulation of adsorbing material 335 from drying to regeneration via the gas in the air duct, saves energy, and is environment-friendly and efficient. The hot air is blown into the upper air duct 150, the wet air is blown into the lower air duct 170, and due to the density characteristics of the hot and cold air, the hot air in the upper air duct 150 and the wet and cold air in the lower air duct 170 are not easy to mix at the paddle machine 300. The protrusion 400 is provided to prevent the hot air from mixing with the air in the lower air duct 170 along the gap, and to slightly change the flow direction of the air below the upper air duct 150, so as to blow the paddle machine 300 to rotate at a proper angle.

One of the frames of the outer frame 331 is connected to the shaft 310 and disposed on the outer circumferential surface of the shaft 310 in a fixed or detachable manner. The first perforated plate member 337 is disposed in the outer frame 331 opposite to the second perforated plate member 339 with a distance between the first perforated plate member 337 and the second perforated plate member 339. The first perforated plate member 337 and the second perforated plate member 339 may be fixedly connected or detachably connected to the outer frame 331. The materials of the outer frame 331, the first perforated plate 337 and the second perforated plate 339 may be selected arbitrarily in order to endure a certain centrifugal force and fix the adsorption material 335 to complete the air drying process. The adsorbing material 335 is fixed in the space formed by the first porous plate member 337 and the second porous plate member 339.
Other structures and embodiments in this embodiment are the same as those in the first embodiment, and are not described herein again.

In addition, the number and the size of the holes on the porous plate can be set according to the requirement of the workplace on the dryness, so that the aim of adjusting the dryness of the dry air is fulfilled.
