Description

Adsorption drying equipment

The present invention relates to an adsorption drying apparatus.

The principle of the adsorption dryer is to distinguish between water molecules and air molecules by using different volumes of water molecules and air molecules. More specifically, the adsorption dryer employs molecular sieves to filter saturated water vapor in the compressed air, which adsorbs water molecules within the molecular sieve particles, thereby producing dry air. Thereafter, the regeneration method is used to reduce the molecular sieve, thereby repeating the recycling.

In a typical adsorption dryer, the exhaust gas used for regeneration instantaneously generates a large amount of noise. The general solution in the industry is to install a silencer on the dryer. However, the effect of the silencer is often less than ideal, and still makes the operator feel extremely uncomfortable.

One aspect of the present invention provides an adsorption drying apparatus which can depressurize a gas stream discharged from a dryer and then discharge it to the outside, so that the adsorption drying apparatus can be quieter when it operates.

According to an embodiment of the present invention, an adsorption drying equipment package Contains skeleton, dryer and regenerative exhaust pipe fittings. The skeleton has at least one muffler exhaust port and a muffler cavity, and the muffler exhaust port is connected to the muffler cavity. The dryer has at least one regeneration vent and a dry gas outlet. The regeneration exhaust pipe member communicates with the regeneration exhaust port and the muffler cavity, so that the airflow discharged through the regeneration exhaust port of the dryer passes through the muffler cavity and is discharged to the outside through the muffler exhaust port.

The above-described embodiments of the present invention have at least the following advantages over the known prior art:

(1) When the dryer is in operation, the airflow discharged by the dryer is first discharged to the muffler chamber, so that the pressure of the airflow is effectively reduced, so that the decompressed airflow is discharged to the outside through the muffler exhaust port. , can also be reduced accordingly, so that the adsorption drying equipment can operate quieter.

The embodiments of the present invention are disclosed in the following drawings, and the details of However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not necessary. In addition, some of the conventional structures and elements are shown in the drawings in a simplified schematic manner in order to simplify the drawings.

Unless otherwise defined, all terms (including technical and scientific terms) used herein are intended to mean the meaning Furthermore, the definition of the above vocabulary in a commonly used dictionary should be interpreted as meaning consistent with the related art of the present invention in the content of the present specification. Unless specifically defined, these terms are not to be interpreted as idealized or overly formal.

Please refer to FIG. 1 , which is a perspective top view of the adsorption drying apparatus 100 according to an embodiment of the present invention. 2 is a perspective lower view of the adsorption drying apparatus 100 of FIG. 1. As shown in FIGS. 1 to 2, the adsorption drying apparatus 100 includes a skeleton 110, a dryer 120, and a regeneration exhaust pipe 130. The skeleton 110 has at least one muffler exhaust port 111 and a muffler chamber 112, and the muffler exhaust port 111 communicates with the muffler chamber 112. The dryer 120 has at least one regeneration exhaust port 121 and a dry gas outlet 122. The regeneration exhaust pipe 130 communicates with the regeneration exhaust port 121 and the muffler chamber 112 so that regeneration is performed via the dryer 120 The airflow discharged from the exhaust port 121 passes through the muffler chamber 112, and is then discharged to the outside via the muffler exhaust port 111.

More specifically, when the dryer 120 is in operation, the airflow discharged from the dryer 120 is first discharged to the muffler chamber 112, so that the pressure of the airflow is effectively reduced, and the decompressed airflow passes through the muffler due to the decompression of the airflow. The noise generated when the port 111 is discharged to the outside can also be correspondingly lowered, so that the dryer 120 can be quieter when it operates.

In a practical application, the method of removing water from the dryer 120 is carried out using a chemical agent, which is called an adsorbent, and is mostly composed of activated aluminum, silicone and/or molecular sieves. The adsorbent can absorb water under different pressures or at different temperatures, and is utilized to achieve the function of adsorbing moisture and removing moisture.

Please refer to FIG. 3 , which is a schematic diagram showing the operation principle of the dryer 120 of FIG. 1 . As shown in Fig. 3, the dryer 120 has two adsorption cylinders 120A, 120B. The humid gas Aw enters the dryer 120. When one adsorption cylinder performs adsorption, such as the adsorption cylinder 120A, the regeneration occurs in the other adsorption cylinder, that is, the adsorption cylinder 120B. The gas to be dehydrated enters the adsorption cylinder 120A by a solenoid valve at the bottom (not shown in Fig. 3), and the adsorbent immediately adsorbs the water gas and water molecules in the humid gas Aw, and directly adsorbs the moisture in the humid gas Aw (grab Living), leaving a dry gas, that is, the dry gas Ad flows out through the upper check valve. At this time, almost no moisture exists in the humid gas Aw to become a dry gas Ad, and the pressure dew point can reach -70 ° C, and the residual moisture can be Less than 0.0002 g/m ³ .

In order to achieve the effect of continuous use, for example, by the adsorption cartridge Most of the dry gas Ad discharged from 120A is discharged outside the dryer 120, and a small portion enters the adsorption cylinder 120B via the flow control valve 120C. Therefore, the pressure in the adsorption cylinder 120B is gradually increased, after reaching the set cycle time. (At this time, the adsorption cylinder 120B usually reaches a certain pressure), and the dry gas Ad in the adsorption cylinder 120B is discharged to the atmosphere through the regeneration exhaust valve 120D with the moisture captured by the previous cycle. Until the beginning of the next cycle, the adsorption cylinders 120A, 120B exchange operations, and the regenerated adsorption cylinder performs the work of adsorbing moisture, and the adsorption cylinder that originally adsorbed moisture starts to regenerate, and thus continues to perform continuously, and provides a very dry dry gas Ad. . However, it should be understood that the operation mode of the above-mentioned dryer 120 is merely illustrative and is not intended to limit the present invention. The present invention is generally known in the art, and should be appropriately designed according to actual needs. The components and their mode of operation.

In the present embodiment, as shown in FIGS. 1 to 2, the skeleton 110 carries the dryer 120 to save space, and the muffler chamber 112 may be located below the dryer 120, but the invention is not limited thereto.

Referring to FIG. 4, a perspective view of an adsorption drying apparatus 100 according to another embodiment of the present invention is shown. As shown in FIG. 4, the adsorption drying apparatus 100 further includes a machine apparatus 150. The machine equipment 150 communicates with the dry gas outlet 122 of the dryer 120, and the skeleton 110 carries the machine equipment 150. In other words, in practical applications, the muffler chamber 112 may be disposed on the skeleton 110 of the carrier machine device 150 in addition to the skeleton (not shown) of the carrier dryer 120. The regeneration exhaust port 121 of the dryer 120 (not shown in FIG. 4) can be connected to the carrier table by regenerating the exhaust pipe member 130. The muffler chamber 112 of the skeleton 110 of the standby 150, as such, the configuration of the adsorption drying apparatus 100 can be more flexible.

Please refer to FIG. 5, which is a perspective view of the adsorption drying apparatus 100 according to still another embodiment of the present invention. In order to further enhance the noise cancellation effect of the adsorption drying apparatus 100, as shown in FIG. 5, the adsorption drying apparatus 100 further includes a first muffler 140. The first muffler 140 is connected to the muffler exhaust port 111 (covered by the first muffler 140 in FIG. 5), and the airflow discharged from the regenerative exhaust port 121 of the dryer 120 enters the muffler through the regenerative exhaust pipe 130. After the cavity 112, it passes through the muffler exhaust port 111 and then is discharged to the outside through the first muffler 140. As a result, the noise cancellation effect of the adsorption drying apparatus 100 can be further effectively improved.

Further, as described above, the airflow that grasps the moisture in the dryer 120 is discharged through the regeneration exhaust port 121 and sent to the muffler cavity 112. Since the water vapor is heavier than the gas, the water vapor is easily discharged to the muffler cavity 112. The first muffler 140 may be located at the bottom of the muffler cavity 112 such that the first muffler 140 may also serve as a drain for moisture.

Please refer to FIG. 6, which is a perspective bottom view of the adsorption drying apparatus 100 according to still another embodiment of the present invention. In the present embodiment, as shown in Fig. 6, the skeleton 110 has at least one exhaust side plate 113, and the number of the muffler exhaust ports 111 is plural and is located at the exhaust side plate 113. Specifically, the diameter of the muffler exhaust port 111 is less than or equal to 2 mm.

Technically, with an appropriate thickness, the exhaust side plate 113 that communicates with the muffler chamber 112 can exert the effect of silencing the microplate. Further, the exhaust side plate 113 having a plurality of muffler exhaust ports 111 is connected to the muffler cavity. 112, and the thickness of the muffler chamber 112 is appropriate, and the exhaust side plate 113 together with the muffler cavity 112 constitutes a microplate silencing structure. The microplate silencer structure is essentially a low sound quality but high acoustic resistance resonant sound absorbing structure. The sound absorption coefficient and the frequency bandwidth of the micro-bubble sound-absorbing structure are mainly determined by the sound quality and acoustic resistance of the micro-bubble sound-absorbing structure, and these two factors are related to the diameter and the perforation rate of the sound-absorbing exhaust port 111.

In order to enable the exhaust side plate 113 to achieve the effect of silencing the microplate, in the present embodiment, as described above, the diameter of the muffler exhaust port 111 is less than or equal to 2 mm, and the flesh side plate 113 has a flesh thickness of less than 2 mm. The flesh thickness of the exhaust side plate 113 and the diameter of the muffler exhaust port 111 reach a size ratio of effective muffling, and the perforation rate (ie, the ratio of the perforated area of the muffler exhaust port 111 to the area of the exhaust side plate 113) is set to 1-5%. However, the invention is not limited thereto. Similarly, as described above, the airflow that grasps the moisture in the dryer 120 is discharged through the regeneration exhaust port 121 and sent to the muffler cavity 112. Since the water vapor is heavier than the gas, in order to make the water vapor easily discharged to the muffler cavity 112, The exhaust side plate 113 may be located at the bottom of the muffler chamber 112, and at least one muffler exhaust port 111 is exhausted toward the bottom direction, so that the muffler exhaust port 111 can also serve as a water discharge port.

Referring to FIG. 7, a perspective partial perspective view of an adsorption drying apparatus 100 in accordance with another embodiment of the present invention is shown. In the present embodiment, as shown in FIG. 7, the frame 110 has a carrier 114, and the carrier 114 has an opposite bearing surface 1141 (covered in FIG. 7) and a bottom surface 1142, and the regenerative exhaust pipe 130 is connected to the bearing. Face 1141. Structurally, the bottom surface 1142 is connected to the muffler cavity 112.

In order to further enhance the noise cancellation effect of the adsorption drying apparatus 100, as shown in FIG. 7, the adsorption drying apparatus 100 further includes a second muffler 160. The second muffler 160 is located on the bottom surface 1142 of the carrier 114 and communicates with the regeneration exhaust pipe 130 (not shown in FIG. 7). That is to say, the airflow discharged by the dryer 120, after regenerating the exhaust pipe member 130, first passes through the second muffler 160 for the first muffling process, and then the airflow will enter the muffler chamber 112 for the second muffling process. Then, it is discharged to the outside through the muffler exhaust port 111 on the exhaust side plate 113 to perform a third muffling process (i.e., the above-mentioned microplate silencing effect). Therefore, the noise cancellation effect of the adsorption drying apparatus 100 can be further effectively improved.

Through the above technical solutions, considerable technological progress can be achieved, and the industrial use value is widely utilized, which has at least the following advantages:

(1) When the dryer is in operation, the airflow discharged by the dryer is first discharged to the muffler chamber, so that the pressure of the airflow is effectively reduced, so that the decompressed airflow is discharged to the outside through the muffler exhaust port. , can also be reduced accordingly, so that the adsorption drying equipment can operate quieter.

(2) Since the muffler chamber can be disposed not only on the skeleton of the load-bearing dryer, but also on the skeleton of the load-bearing machine, and the regeneration exhaust port of the dryer can be connected to the load-bearing machine through the regeneration of the exhaust pipe. The silencing chamber of the skeleton, therefore, the configuration of the adsorption drying device can be more flexible.

(3) Since the adsorption drying device can further include the first muffler, The airflow discharged by the dryer passes through the muffler vent and then is discharged to the outside through the first muffler. Therefore, the muffling effect of the adsorption drying device can be further effectively improved.
