Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dryers, and more specifically, to a structure of an adsorption dryer. Background Art
[0002] An adsorption dryer (desiccant dryer) mainly consists of an adsorption barrel, a regeneration barrel, an air compressor, a cooler, etc. During operation, the adsorption barrel and the regeneration barrel operate intermittently and alternately. When one barrel (adsorption barrel) is working, the other barrel (regeneration barrel) regenerates the internal adsorbent. Generally, the compressed hot air generated by the air compressor is used to take away the moisture inside the adsorbent in the regeneration barrel so that the regeneration barrel can become an adsorption barrel for reuse. And generally, the hot air is cooled by a cooler, and the cooled air then passes through the adsorption barrel for adsorption drying. During the production and supply process of compressed air, drying equipment is needed to dehumidify the produced compressed air to meet the dew point requirements of the end-use equipment.
[0003] Currently, when the desiccant dryer is in use, some gases are directly discharged into the air from the discharge pipeline, which may cause some adsorbent impurities to be discharged with the gases, thereby gradually weakening the gas purification and treatment ability, and causing environmental pollution in the processing area air, and then greatly reducing the cleanliness of the processing area air environment. In addition, when the desiccant dryer is converted from the regeneration barrel to the adsorption barrel, there is still heat in the barrel, that is, high-temperature air is needed when the adsorbent is regenerated. After the regeneration is completed, the adsorbent still has a certain temperature, and the discharged gas has a high temperature, and directly discharging it also poses a safety risk. Summary of the Utility Model
[0004] The problems to be solved by the utility model are: how to avoid the pollution of the working area environment caused by the gases discharged from the desiccant dryer, and how to avoid the safety risks of the high-temperature gases discharged from the desiccant dryer.
[0005] The utility model provides a structure of an adsorption dryer, including: a desiccant dryer body and a cooler. An inlet pipeline, an outlet pipeline and a discharge pipeline are arranged on the desiccant dryer body. The cooler includes a first cooling pipe group and a second cooling pipe group. The two ends of the first cooling pipe group are respectively a first inlet and a first outlet, and the two ends of the second cooling pipe group are respectively a second inlet and a second outlet. The inlet pipeline is connected to the first outlet, the outlet pipeline is connected to the second inlet, and the discharge pipeline is connected to the first inlet.
[0006] The structure of the adsorption dryer provided by the utility model, compared with the prior art, has but is not limited to the following beneficial effects:
[0007] The adsorption dryer structure described in the present utility model, where the dryer body is a prior art. A control pipeline is provided thereon, and an inlet pipeline, an outlet pipeline, and a discharge pipeline are provided on the control pipeline. Gas can be introduced into the adsorption barrel of the dryer body from the inlet pipeline. After the gas is dried by the adsorption particles in the adsorption barrel, a part of the gas enters the regeneration barrel after being pressurized. After the gas dries the adsorption particles in the regeneration barrel, it then sequentially passes through the discharge pipeline and the first inlet and enters the first cooling pipe group. Another part sequentially enters the second cooling pipe group from the outlet pipeline and the second inlet. The gas in the first cooling pipe group and the second cooling pipe group is cooled simultaneously. Subsequently, the gas in the first cooling pipe group sequentially enters the adsorption barrel of the dryer body from the first outlet and the inlet pipeline, and the gas in the second cooling pipe group is sent to each gas-using device from the second outlet. Compared with the prior art, in the adsorption dryer structure of the present utility model, after the gas discharged from the dryer body through the discharge pipeline is cooled in the first cooling pipe group, the gas is sent back into the inlet of the dryer body again, which can prevent the gas discharged from the dryer from being directly discharged into the atmosphere, avoid some adsorbent impurities from being discharged with the dried gas, and cause pollution to the working area environment. In addition, when the regeneration barrel is converted into an adsorption barrel, there is still heat in the barrel. Therefore, after the gas at the outlet of the dryer body is introduced into the second cooling pipe group for cooling and then sent to each gas-using device, the safety risk of the high-temperature gas discharged from the dryer can be avoided.
[0008] Optionally, the cooler further includes a housing. An inlet for introducing chilled water into the housing and an outlet for discharging the chilled water are provided on the housing. The first cooling pipe group and the second cooling pipe group are arranged at intervals in the housing, and the first inlet, the first outlet, the second inlet, and the second outlet respectively extend outside the housing.

[0025] As Figures 1 to 2 shown, the structure of the adsorption dryer according to the embodiment of the present utility model includes: a desiccant dryer body 1 and a cooler. An inlet pipeline 101, an outlet pipeline 102, and a discharge pipeline 103 are provided on the desiccant dryer body 1. The cooler includes a first cooling tube group 3 and a second cooling tube group 4. The two ends of the first cooling tube group 3 are respectively a first inlet 9 and a first outlet 10. The two ends of the second cooling tube group 4 are respectively a second inlet 11 and a second outlet 12. The inlet pipeline 101 is connected to the first outlet 10. The outlet pipeline 102 is connected to the second inlet 11. The discharge pipeline 103 is connected to the first inlet 9.
[0026] In this embodiment, in combination with the attached Figure 1 and the attached Figure 2 shown, the desiccant dryer body 1 of the structure of this adsorption dryer is a prior art, that is, the desiccant dryer body 1 is an adsorption dryer in the prior art. A control pipeline is provided thereon, and an inlet pipeline 101, an outlet pipeline 102, and a discharge pipeline 103 are provided on the control pipeline. Gas can be introduced into the adsorption barrel of the desiccant dryer body 1 from the inlet pipeline 101. After the gas is dried by the adsorption particles in the adsorption barrel, the gas dried by the adsorption barrel is divided into two parts. One part of the gas enters the regeneration barrel after being pressurized. After the gas dries the adsorption particles in the regeneration barrel, it then sequentially passes through the discharge pipeline 103 and the first inlet 9 and enters the first cooling tube group 3. Then, after cooling in the first cooling tube group 3, it then sequentially returns from the first outlet 10 and the inlet pipeline 101 to the adsorption barrel of the desiccant dryer body 1, thereby forming a gas circulation process. This gas circulation process can dry the adsorption particles in the regeneration barrel; the other part of the gas dried by the adsorption barrel sequentially enters the second cooling tube group 4 from the outlet pipeline 102 and the second inlet 11. After cooling in the second cooling tube group 4, it is sent from the second outlet 12 to each gas-using device. Specifically, in combination with the attached Figure 1As shown, when bucket X is the adsorption bucket and bucket Y is the regeneration bucket, the gas sequentially passes through the inlet pipeline 101 and valve a and enters the adsorption bucket X. The gas dried by the adsorption bucket X is split into two parts. One part of the gas sequentially passes through valve g, outlet pipeline 102, and second inlet 11 and enters the second cooling pipe group 4. The other part of the gas dried by the adsorption bucket X sequentially passes through valve g, valve i, and valve f and enters the regeneration bucket Y. After drying the adsorption particles in the regeneration bucket Y, the gas then sequentially passes through valve d, discharge pipeline 103, and first inlet 9 and enters the first cooling pipe group 3. Similarly, when bucket X is the regeneration bucket and bucket Y is the adsorption bucket, the gas sequentially passes through the inlet pipeline 101 and valve b and enters the adsorption bucket Y. The gas dried by the adsorption bucket Y is split into two parts. One part of the gas sequentially passes through valve h, outlet pipeline 102, and second inlet 11 and enters the second cooling pipe group 4. The other part of the gas dried by the adsorption bucket Y sequentially passes through valve h, valve i, and valve e and enters the regeneration bucket X. After drying the adsorption particles in the regeneration bucket X, the gas then sequentially passes through valve c, discharge pipeline 103, and first inlet 9 and enters the first cooling pipe group 3. In the adsorption dryer structure of the present utility model, compared with the prior art, the gas discharged from the dryer body 1 through the discharge pipeline 103 enters the first cooling pipe group 3 for cooling and then is sent back to the inlet (inlet pipeline 101) of the dryer body 1 again, which can prevent the gas discharged from the dryer from being directly discharged into the atmosphere and avoid some adsorbent impurities from being discharged with the drying gas, thus causing pollution to the working area environment. In addition, when the regeneration bucket is converted into the adsorption bucket, there is still heat in the bucket. Therefore, the gas at the outlet (outlet pipeline 102) of the dryer body 1 is passed through the second cooling pipe group 4 for cooling and then sent to each gas-using device, which can avoid the safety risks of the high-temperature gas discharged from the dryer.
[0027] Optionally, the cooler further includes a housing 2. A liquid inlet 7 for introducing chilled water into the housing 2 and a liquid outlet 8 for discharging the chilled water are provided on the housing 2. The first cooling pipe group 3 and the second cooling pipe group 4 are arranged at intervals in the housing 2, and the first inlet 9, the first outlet 10, the second inlet 11, and the second outlet 12 respectively extend outside the housing 2.
[0028] In this embodiment, in combination with the attached Figure 2 As shown, the housing 2 can be a rectangular box structure. The first cooling pipe group 3 and the second cooling pipe group 4 are arranged at intervals in the housing 2. A liquid inlet 7 for introducing chilled water into the housing 2 and a liquid outlet 8 for discharging the chilled water are provided on the housing 2. The first cooling pipe group 3 and the second cooling pipe group 4 can be cooled simultaneously by the chilled water in the housing 2, which can effectively reduce resource waste.
[0029] Optionally, both the first cooling pipe group 3 and the second cooling pipe group 4 are arranged in a continuous S-shaped structure in the housing 2.
[0030] In this embodiment, in combination with Figure 2 As shown, the extending directions of the S-shaped structures of the first cooling pipe group 3 and the second cooling pipe group 4 are the same, and the two can be symmetrically arranged in the housing 2. Arranging both the first cooling pipe group 3 and the second cooling pipe group 4 in a continuous S-shaped structure is beneficial to increasing the contact area between the chilled water and the first cooling pipe group 3 and the second cooling pipe group 4, and ensuring the cooling effect of the gas in the first cooling pipe group 3 and the second cooling pipe group 4.
[0031] Optionally, a plurality of partition plates 5 are spaced inside the housing 2, and the plurality of partition plates 5 together enclose a continuous S-shaped chilled water channel.
[0032] In this embodiment, in combination with the attached Figure 2 As shown, a plurality of partition plates 5 inside the housing 2 together enclose a continuous S-shaped chilled water channel, which can increase the contact area between the chilled water and the first cooling pipe group 3 and the second cooling pipe group 4, and ensure the cooling effect of the gas in the first cooling pipe group 3 and the second cooling pipe group 4. Specifically, as Figure 2 shown, the S-shaped chilled water channel is perpendicular to the extending directions of the S-shaped structures of the first cooling pipe group 3 and the second cooling pipe group 4, which is beneficial to improving the heat exchange efficiency.
[0033] Optionally, the housing 2 includes a first half-shell 201 and a second half-shell 202, and the first half-shell 201 and the second half-shell 202 are detachably connected.
[0034] In this embodiment, in combination with the attached Figure 2 As shown, the housing 2 is a split structure, which includes a first half-shell 201 and a second half-shell 202 that are detachably connected to each other. A first flange may be provided on the end face of the first half-shell 201 facing the second half-shell 202, and a second flange may be provided on the end face of the second half-shell 202 facing the first half-shell 201. The first flange and the second flange can be connected by bolts to connect the first half-shell 201 and the second half-shell 202 into one body. By the detachable connection between the first half-shell 201 and the second half-shell 202, it is beneficial to the assembly and maintenance of the housing 2 and the first cooling pipe group 3 and the second cooling pipe group 4 inside.
[0035] Optionally, in combination with the attached Figure 2 As shown, a sealing gasket 6 is provided between the first half-shell 201 and the second half-shell 202.
[0036] In this embodiment, a sealing gasket 6 is provided between the first half-shell 201 and the second half-shell 202 to ensure the sealing performance of the housing 2 after the first half-shell 201 and the second half-shell 202 are connected.

[0039] Optionally, a filter 14 is installed on the inlet pipeline 101.
[0040] In this embodiment, as shown in the attached Figure 1 figure, a filter 14 is installed on the inlet pipeline 101, and the first outlet 10 is connected to the inlet of the filter 14, improving the cooling effect of the first cooling pipe group 3 and the second cooling pipe group 4. The filter 14 can filter the gas at the inlet of the dryer body 1 and the dried gas, improving the purification effect of the dried gas and effectively reducing gas consumption.
[0041] Optionally, a gas-liquid separator 13 is provided between the inlet pipeline 101 and the first outlet 10, and the outlet of the gas-liquid separator 13 is connected to the inlet of the filter 14.
[0042] In this embodiment, as shown in the attached Figure 1 figure, a gas-liquid separator 13 is provided between the first outlet 10 and the inlet pipeline 101, and the outlet of the gas-liquid separator 13 is connected to the inlet of the filter 14.

[0043] The working process of the structure of this adsorption dryer is as follows: Gas is introduced from the inlet pipeline 101 into the adsorption barrel of the dryer body 1. After the gas is dried by the adsorption particles in the adsorption barrel, a part of the gas enters the regeneration barrel after being pressurized.
