Description

Technical Field

[0001] The present application relates to the technical field of compressed air drying, and in particular to an energy-saving dryer. Background Art

[0002] Common compressed air dryers are divided into two types: refrigerated compressed air dryers and adsorption compressed air dryers. Refrigerated compressed air dryers reduce the air temperature and extract moisture from the air to obtain relatively dry air. Adsorption compressed air dryers use the principle of pressure swing adsorption to pass air through an adsorbent, and then the moisture is adsorbed by the adsorbent to obtain dry air.

[0003] The existing dryer has only one set of adsorption towers, so if there is too much moisture in the adsorbent, the adsorbent needs to be processed before it can be used again, which affects work efficiency. Summary of the invention

[0004] The purpose of the present application is to provide an energy-saving dryer in order to solve the above-mentioned problem. Two groups of adsorption towers are used alternately. When one group is working, the adsorbent in the other group of adsorption towers can be regenerated, thereby improving the working efficiency. At the same time, the regeneration of the adsorbent reduces resource waste and energy consumption.

[0005] This application achieves the above objectives through the following technical solutions:

[0022] 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 part of the embodiments of the present application, rather than all of the embodiments.

[0023] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the attached Figure 1 , and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0024] like Figure 1-4 As shown, an energy-saving dryer includes a first adsorption tower 1 and a second adsorption tower 2. The first adsorption tower 1 and the second adsorption tower 2 are both provided with adsorption components. The adsorption components include partitions 10. The partitions 10 are an even number. The partitions 10 are arranged in the vertical direction. The partitions 10 are densely provided with air holes 11. There is a gap between every two partitions 10 to form a cavity for storing adsorbents, and there is an air diffusion cavity 19 for air circulation between adjacent cavities, and there is a gap between the bottom partition 10 and the bottom of the first adsorption tower 1 or the second adsorption tower 2. The tops of the first adsorption tower 1 and the second adsorption tower 2 are provided with connected exhaust components, and the bottoms of the first adsorption tower 1 and the second adsorption tower 2 are provided with connected air intake components. The bottoms of the first adsorption tower 1 and the second adsorption tower 2 are connected with hot air components for blowing hot air into the adsorbent to dry it for regeneration.

[0025] Specifically, the gas can flow through the pores 11 and the air diffusion chamber 19, and the adsorbent in the cavity absorbs moisture in the passing air. There is a gap between the bottom partition 10 and the first adsorption tower 1 so that the air entering the first adsorption tower 1 and the second adsorption tower 2 from the air inlet pipe 7 can diffuse in the gap before being adsorbed by the adsorbent, so that the adsorbent can evenly absorb moisture.

[0026] Furthermore, the air intake assembly includes an air intake pipe 7, a first solenoid valve 8, and a centralized air intake pipe 9. There are two air intake pipes 7, and the first ends of the air intake pipes 7 are respectively connected to the first adsorption tower 1 and the second adsorption tower 2. The air intake pipes 7 are each provided with a first solenoid valve 8, and the second ends of the air intake pipes 7 are each connected to the centralized air intake pipe 9.

[0027] Specifically, the gas enters the intake pipe 7 from the centralized intake pipe 9, and then enters the first adsorption tower 1 or the second adsorption tower 2 from the intake pipe 7. When passing through one of the intake pipes 7, the first solenoid valve 8 on the other intake pipe 7 is closed.

[0028] Furthermore, the exhaust component includes a dry air pipe 3, a second solenoid valve 4, and a centralized dry air pipe 6. There are two dry air pipes 3, and the first ends of the dry air pipes 3 are respectively connected to the first adsorption tower 1 and the second adsorption tower 2. The dry air pipes 3 are each provided with a second solenoid valve 4, and the second ends of the dry air pipes 3 are each connected to the centralized dry air pipe 6.

[0029] Specifically, the dry gas is discharged from the dry gas pipe 3 to the centralized dry gas pipe 6, and then discharged from the centralized dry gas pipe 6. When the dry gas passes through one of the dry gas pipes 3, the second solenoid valve 4 on the other dry gas pipe 3 is in a closed state.

[0030] Furthermore, the hot air component includes a hot air pipe 16, a third solenoid valve 17, and a hot air blower 18. The two ends of the hot air pipe 16 are respectively connected to the gap between the first adsorption tower 1 and the second adsorption tower 2 and the bottom partition 10, and the third solenoid valve 17 is arranged near the two ends of the hot air pipe 16. The hot air blower 18 is connected to the two ends of the hot air pipe 16 for transporting hot air into the hot air pipe 16.

[0031] Specifically, when there is no need to heat the adsorbent, the two third solenoid valves 17 are in a closed state. When the adsorbent in the first adsorption tower 1 or the second adsorption tower 2 needs to be processed, the third solenoid valve 17 near the first adsorption tower 1 or the second adsorption tower 2 is controlled to be in an open state, and then the hot air blower 18 generates hot air and sends it into the hot air pipe 16, and then enters the first adsorption tower 1 or the second adsorption tower 2 from the hot air pipe 16, and then dries the adsorbent.

[0032] Furthermore, the four sides of the partition 10 are fixedly connected to the first adsorption tower 1 or the second adsorption tower 2, the partition 10 is tilted, and the side wall of the first adsorption tower 1 on the side where the partition 10 is high is provided with a baffle 12 for opening and closing the cavity.

[0033] Specifically, the four sides of the partition 10 are sealed and fixedly connected to the first adsorption tower 1 or the second adsorption tower 2 to prevent gas leakage from between the partition 10 and the first adsorption tower 1 or the second adsorption tower 2, so that the gas can flow smoothly through the pores 11. The switch door 12 is convenient for taking and placing the adsorbent, and the inclined partition 10 is convenient for storing the adsorbent.

[0034] Furthermore, it also includes an exhaust pipe 13, an exhaust collecting pipe 14 and a fourth solenoid valve 15. There are multiple exhaust pipes 13, and each of them is connected to the air diffusion chamber 19. The end of the exhaust pipe 13 away from the air diffusion chamber 19 is connected to the fourth solenoid valve 15. The fourth solenoid valve 15 is provided at one end of the fourth solenoid valve 15 for exhaust.

[0035] Specifically, when drying the adsorbent, the fourth solenoid valve 15 on the exhaust gas collecting pipe 14 connected to the first adsorption tower 1 or the second adsorption tower 2 is in an open state, and then the gas used to dry the adsorbent is discharged from the exhaust gas pipe 13 and the exhaust gas collecting pipe 14. When the adsorbent does not need to be dried, the fourth solenoid valve 15 is in a closed state to avoid leakage of dry gas.

[0036] Furthermore, a humidity sensor 5 is provided on the drying air pipe 3 to detect the humidity.

[0037] Furthermore, the first adsorption tower 1 and the second adsorption tower 2 are fixedly connected to each other, and a bracket 20 is fixedly connected to the side wall for supporting the first adsorption tower 1 and the second adsorption tower 2 .

[0038] In the above structure, the air to be adsorbed with moisture enters the air intake pipe 7 from the centralized air intake pipe 9, and then enters the first adsorption tower 1 or the second adsorption tower 2 from the air intake pipe 7. When one of the first adsorption tower 1 or the second adsorption tower 2 is working, the second solenoid valve 4 and the first solenoid valve 8 on the other are in a closed state, and the fourth solenoid valve 15 and the third solenoid valve 17 are also in a closed state. Then, the air is adsorbed with moisture in the air by the adsorbent between the two adjacent partitions 10, and then the dry air is discharged from the drying air pipe 3. The second solenoid valve 4 can detect the humidity in the air passing through the drying air pipe 3. When the humidity value increases, the second solenoid valve 4 and the first solenoid valve 8 are controlled. The magnetic valve 8 is closed or opened to allow the air with moisture to be adsorbed to flow through the first adsorption tower 1 or the second adsorption tower 2. When the adsorbent needs to be regenerated, the hot air blower 18 is started to blow into the first adsorption tower 1 or the second adsorption tower 2 through the hot air pipe 16. When it is necessary to blow into the first adsorption tower 1, the third solenoid valve 17 near the second adsorption tower 2 is closed. When it is necessary to blow into the second adsorption tower 2, the third solenoid valve 17 near the first adsorption tower 1 is closed. The hot air enters the bottom of the first adsorption tower 1 or the second adsorption tower 2, passes through the adsorbent, and then evaporates the moisture in the adsorbent and is discharged from the exhaust pipe 13 and the exhaust gas collecting pipe 14, so as to regenerate the adsorbent, avoid waste of resources, and save energy.
