A cleanroom fresh air energy-saving system

Abstract

This invention discloses a cleanroom fresh air energy-saving system, including an air intake mechanism and a cleanroom. The cleanroom has partitions on both sides, and return air ducts are formed on both sides. Air vents are provided below the partitions. The air intake assembly includes an air intake pipe located above the cleanroom, and an air intake hood is installed below the air intake pipe, corresponding to the cleanroom. Water-filtering cotton is installed on the side of the air vents away from the return air ducts, and absorbent cotton is stacked on top of the water-filtering cotton. A humidity recovery pipe is installed on the air intake hood. This invention uses water-filtering cotton on the air vents, absorbent cotton stacked on top of the water-filtering cotton, and a humidity recovery pipe on the air intake hood. This allows the airflow exiting from the humidity recovery pipe to pass through the water-filtering cotton, carrying away the moisture filtered by the incoming air, reducing the workload of the humidity adjustment structure, and achieving energy savings.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the accompanying drawings of the embodiments of the present invention will be used in conjunction with the following.

[0017] Please see Figure 1 As shown in the embodiment of the present invention, a cleanroom fresh air energy-saving system includes an air intake component and a cleanroom 6. The air intake component includes a fan unit 16. A temperature and humidity adjustment component 2 is installed at the air intake end of the fan unit 16. A filter component 3 is installed on the side of the temperature and humidity adjustment component 2 away from the fan unit 16. The other end of the filter component 3 is fixedly connected to a fresh air duct 4. When the fan unit 16 is working, it can introduce outside fresh air into the interior of the filter component 3 for filtration. After filtration, the air reaches the interior of the temperature and humidity adjustment component 2 for temperature and humidity adjustment. The exhaust port of the fan unit 16 is connected to a silencer pipe 1, that is, the air after temperature and humidity adjustment can be silenced by the silencer pipe 1.

[0018] Combination Figure 1 and Figure 2 As shown, partitions 61 are provided on both sides of the interior of the cleanroom 6, and return air ducts 62 are provided on both sides of the cleanroom 6. Air holes 63 are provided below the partitions 61. The air intake assembly includes an air intake pipe 15, which is located above the cleanroom 6. An air intake hood 14 is installed below the air intake pipe 15 corresponding to the cleanroom 6. The silencer pipe 1 is fixedly connected to the air intake pipe 15. That is, the airflow after the silencer pipe 1 has been silenced can reach the interior of the air intake hood 14 through the air intake pipe 15 and be discharged into the interior of the cleanroom 6 so that the internal air temperature and humidity of the cleanroom 6 are in the required state.

[0019] Combination Figure 1 The return air duct 62 is equipped with return pipes 5 on both sides above it. The air inside the clean room 6 can reach the inside of the return air duct 62 through the air hole 63, and then reach the inside of the return pipe 5. A heat exchange box 10 is installed at one end of the return pipe 5, and a connecting pipe 51 is fixedly connected to the other end of the heat exchange box 10. The connecting pipe 51 is fixedly connected to the end of the filter assembly 3 near the fresh air duct 4. After the return pipe 5 exchanges heat inside the heat exchange box 10, it can return to the inside of the filter assembly 3 through the connecting pipe 51.

[0020] Combination Figure 1 Inside the heat exchange box 10, there is a heat exchange tube 11. The heat exchange tube 11 is spiral-shaped, and a temperature recovery tube 111 is provided between the two ends of the heat exchange tube 11. The temperature recovery tube 111 is located below the air inlet hood 14. That is, the water inside the heat exchange tube 11 can absorb the temperature inside the return pipe 5 and reach the inside of the temperature recovery tube 111. The airflow blown downward from the air inlet hood 14 can pass through the temperature recovery tube 111 and absorb its temperature. The airflow temperature inside the clean room 6 can further meet the requirements, thereby reducing the temperature regulation workload of the temperature and humidity adjustment component 2.

[0021] Combination Figure 1 and Figure 2 As shown, a water-filtering cotton 7 is installed on the side of the air vent 63 away from the return air duct 62. That is, the air discharged from the air vent 63 to the return air duct 62 can first be filtered to remove moisture by the water-filtering cotton 7. A water-absorbing cotton 8 is stacked on top of the water-filtering cotton 7. The water-absorbing cotton 8 can absorb the moisture on the water-filtering cotton 7. A humidity recovery pipe 13 is installed on the air inlet hood 14. A branch pipe 12 is installed at the lower end of the humidity recovery pipe 13. An air outlet hood 9 is fixed to the lower end of the branch pipe 12. The position of the air outlet hood 9 corresponds to the water-absorbing cotton 8. That is, part of the airflow discharged from the air inlet hood 14 can reach the humidity recovery pipe 13, then reach the inside of the branch pipe 12, and be discharged from the air outlet hood 9 onto the water-absorbing cotton 8. After carrying moisture, it can reach the inside of the clean room 6.

[0022] The working principle of this invention is:

[0023] When using this device, the fan unit 16 operates and introduces fresh air from outside into the filter assembly 3 for filtration. After filtration, the air reaches the temperature and humidity adjustment assembly 2 for temperature and humidity adjustment. Then, the airflow reaches the silencer duct 1 and then the air inlet duct 15, finally being ejected from the air inlet hood 14 into the clean room 6. The airflow from the lower part of the clean room 6 can then reach the return air duct 62 through the air hole 63. When passing through the air hole 63, the water filter cotton 7 filters out the moisture. The water absorbent cotton 8 is stacked on top of the water filter cotton 7 and can absorb the moisture on the water filter cotton 7. Part of the airflow discharged from the air inlet hood 14 can reach the humidity recovery pipe 13 and then the branch pipe 12. The air is discharged from the exhaust hood 9 onto the absorbent cotton 8, and after carrying moisture, it can reach the interior of the clean room 6 (which can reduce the workload of the humidity adjustment structure in the temperature and humidity adjustment component 2). The airflow that reaches the return air duct 62 can reach the interior of the heat exchange box 10 through the return pipe 5 and exchange heat with the heat exchange tube 11. Then the exhaust gas continues to return through the connecting pipe 51. The water inside the heat exchange tube 11 can absorb the temperature inside the return pipe 5 and reach the interior of the temperature recovery pipe 111. The airflow blown downward from the air inlet hood 14 can absorb its temperature through the temperature recovery pipe 111, and the temperature of the airflow that reaches the interior of the clean room 6 can further meet the requirements, thereby reducing the temperature adjustment workload of the temperature and humidity adjustment component 2.
