Description

Technical Field

[0001] This utility model belongs to the field of air purification technology, and specifically relates to a cleanroom air dehumidification and filtration device. Background Technology

[0002] Currently, Chinese utility model patent CN217367603U discloses an air filtration device for cleanrooms. This filtration device has the following defects during use: traditional cleanroom air filtration devices do not have dehumidification function, or the dehumidification function is not obvious. At the same time, it may cause the fan to overheat and affect its lifespan. The accumulated condensate water is prone to breed bacteria and contaminate the clean environment, and the maintenance cost will also increase significantly.

[0003] To address the problems mentioned in the background above, a cleanroom air dehumidification and filtration device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a cleanroom air dehumidification and filtration device, which has the advantages of air dehumidification and secondary utilization of condensate.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cleanroom air dehumidification and filtration device, comprising an outer tube, a filter one fixedly sleeved on the left side of the inner wall of the outer tube away from the middle, a filter two fixedly sleeved on the left side of the inner wall of the outer tube near the middle, a heat-conducting plate one embedded in the middle of the top of the outer tube, a fan embedded in the middle of the top of the outer tube, an aluminum plate welded to the bottom of the heat-conducting plate one, a frame fixedly sleeved on the right side of the inner wall of the outer tube near the middle, heat pipes sleeved on the top and bottom of the frame, a fan bolted to the top of the right side of the outer tube away from the middle, a water tank embedded in the middle of the bottom of the outer tube, and a heat dissipation mechanism provided on the right side of the water tank.

[0006] The above technical solution involves the following steps: Indoor air is drawn into the device by a fan and filtered first by filters one and two. Filter one efficiently intercepts large particulate pollutants, while filter two precisely filters small particulates. The clean air then comes into contact with an aluminum plate. The heat-conducting plate on top of the aluminum plate absorbs heat, which is then dissipated by the top fan. The air in contact with the aluminum plate undergoes a condensation reaction, and the condensate drips into the bottom water tank. The air that has absorbed moisture is further dried by the heat pipes behind it and is finally exhausted back into the room by the fan. This effectively reduces indoor air humidity and maintains cleanliness. The pre- and medium-efficiency filters remove particulate pollutants, and the aluminum plate condensation system utilizes the principle of temperature difference to achieve efficient dehumidification. The heat pipe structure further ensures that the air is dry. The entire process requires no chemical desiccant, is simple to maintain, and has low energy consumption, making it particularly suitable for clean environments that are sensitive to temperature and humidity.

[0007] The present invention is further configured such that the heat dissipation mechanism includes a water inlet pipe, which passes through and is sleeved on the right side of the water tank. A water pump is connected to the right side of the water inlet pipe, and the bottom of the outer pipe is embedded in the top of the water pump. A water outlet pipe is connected to the right side of the water pump, and a heat-conducting plate is embedded in the bottom of the outer pipe on the right side away from the middle.

[0008] The above technical solution involves a water pump that draws the condensate stored in the water tank into the inlet pipe. The condensate then flows from the inlet pipe into the pump and into the outlet pipe. The heat generated by the fan is absorbed by the bottom heat-conducting plate 2. The condensate in the inlet pipe absorbs the heat from the heat-conducting plate 2 and is finally discharged from the drain pipe. As the condensate flows through the heat-conducting plate 2, it absorbs the heat from the fan, improving heat dissipation efficiency. At the same time, it avoids the problem of microbial growth caused by condensate accumulation. This integrated design optimizes the thermal management of the equipment and simplifies the drainage system structure, making the device more stable and efficient in operation.

[0009] The present invention is further configured such that the filter is a pre-filter.

[0010] The above technical solution is adopted: by setting it as a pre-filter, it can efficiently intercept large particulate pollutants. It is made of materials such as non-woven fabric or metal wire mesh, with simple structure, low resistance and high dust holding capacity, and is easy to clean or replace in batches.

[0011] The present invention is further configured such that the second filter is a medium-efficiency filter.

[0012] The above technical solution is adopted: by setting it as a medium-efficiency filter, it can accurately filter small particulate matter, and adopts a bag or plate structure, with a large filtration area and moderate resistance.

[0013] The present invention is further configured such that the heat-conducting plate one and the heat-conducting plate two are made of copper plates.

[0014] The above technical solution is adopted: by setting it as a copper plate, the copper plate has good thermal conductivity, corrosion resistance and other characteristics, and is suitable for working in high temperature and high pressure environments.

[0015] The present invention is further configured such that a drain pipe is connected to the right side of the water outlet pipe.

[0016] The above technical solution involves installing a drain pipe to remove condensate from the inlet pipe.

[0017] The present invention is further configured such that a filter screen is sleeved on the right side of the outer tube.

[0018] By adopting the above technical solution, a filter screen can be installed to prevent dust and impurities from entering the device from the right side.

[0019] The present invention is further configured such that mounting brackets are bolted to both sides of the top of the outer tube.

[0020] The above technical solution allows for convenient installation of the device by setting up a mounting bracket.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model can effectively reduce indoor air humidity and maintain cleanliness. The pre-filter and medium-efficiency filter remove particulate pollutants first, and the aluminum plate condensation system uses the temperature difference principle to achieve efficient dehumidification. The heat pipe structure further ensures that the air is dry. The whole process does not require chemical dehumidifiers, is simple to maintain and has low energy consumption, and is especially suitable for use in clean environments that are sensitive to temperature and humidity.

[0023] 2. This utility model improves heat dissipation efficiency by absorbing heat from the fan when condensate flows through the heat-conducting plate, while avoiding the problem of microbial growth caused by condensate accumulation. This integrated design optimizes the thermal management of the equipment and simplifies the drainage system structure, making the device operate more stably and efficiently.
