[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Different industries have varying environmental requirements, especially in the refrigeration industry, such as warehouses, factory equipment rooms, and anti-static rooms. Companies typically use air conditioning year-round to cool environments requiring cooling to meet their environmental needs. Most businesses use residential air conditioners to lower indoor or ambient temperatures to ensure normal process operation. However, typical residential air conditioners cannot meet cooling needs in winter when outdoor temperatures are relatively low. Additionally, some factory environments have high humidity requirements, which ordinary residential refrigeration units cannot meet.

[0004] Traditional refrigeration systems fail in low-temperature environments, forcing companies to use energy-intensive electric auxiliary heating to maintain cooling, significantly increasing operating costs. Temperature and humidity differences also affect air volume, leading to substantial differences in production output. While current cooling and dehumidification devices can achieve dehumidification and cooling, their efficiency is low. In environments with high humidity and low outdoor temperatures, they cannot quickly dehumidify and cool, resulting in unstable overall process operation. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an air separation cooling and dehumidification device that can achieve rapid dehumidification and cooling, improve the efficiency of dehumidification and cooling, and can rapidly dehumidify and cool the air in environments with high air humidity and high outdoor temperature, ensuring the stable operation of the overall process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An air separation cooling and dehumidification device includes an air filter, an air cooling and dehumidifier, and an air compressor; the outlet end of the air filter is connected to the inlet end of the air cooling and dehumidifier, and the outlet end of the air cooling and dehumidifier is connected to the inlet end of the air compressor.

[0008] The air cooling and dehumidifying unit includes an outer shell, a cooler, a baffle plate, and a dehumidifying filter membrane. The cooler is installed inside the outer shell, a baffle plate is installed at one end of the cooler, and a dehumidifying filter membrane is installed at one end of the baffle plate.

[0009] Furthermore, the baffle plate is provided with a curved channel, and the baffle plate is detachably connected to the outer shell.

[0010] Furthermore, the dehumidifying filter membrane is provided with membrane flow channels, which are arranged obliquely.

[0011] Furthermore, an inspection ladder is provided on the inner side of the outer casing, and the inspection ladder is detachably connected to the outer casing.

[0012] Furthermore, a protective net is provided at one end of the dehumidifying filter membrane.

[0013] Furthermore, the protective net is disposed inside the outer casing, and the protective net is detachably connected to the outer casing.

[0014] Furthermore, the air filter and the air cooling and dehumidifier are connected by a pipe, and a first valve is installed on the pipe connecting the air filter and the air cooling and dehumidifier.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are:

[0019] This invention comprises an air filter, an air cooling and dehumidifier, and an air compressor. The air cooling and dehumidifier includes a cooler that allows air to exchange heat with chilled water, turning it into a low-temperature gas. As the temperature decreases, water vapor in the air condenses and enters a baffle plate, where it undergoes secondary separation with the dehumidifying filter membrane. This removes the condensed water and entrained droplets from the air, thereby increasing the airflow to the compressor. The compressor, connected after the dehumidifier, compresses the gas into a high-temperature, high-pressure gas. In high humidity conditions, the multi-directional structure of the baffle plate increases the efficiency of mist capture, and the dehumidifying filter membrane absorbs water, achieving rapid dehumidification and cooling. This improves dehumidification and cooling efficiency and enables rapid dehumidification and cooling in environments with high humidity and low outdoor temperatures, ensuring stable operation of the entire process.

[0024] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0025] Traditional refrigeration systems fail in low-temperature environments, forcing companies to use energy-intensive electric auxiliary heating to maintain cooling, significantly increasing operating costs. Temperature and humidity differences also affect air volume, leading to substantial output variations. While current cooling and dehumidification devices can achieve dehumidification and cooling, their efficiency is low. In environments with high humidity and low outdoor temperatures, they cannot quickly dehumidify and cool, resulting in unstable overall process operation.

[0026] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses an air separation cooling and dehumidification device, such as... Figure 1 As shown, it includes an air filter 1, an air cooling and dehumidifying unit 2, and an air compressor 3; the outlet end of the air filter 1 is connected to the inlet end of the air cooling and dehumidifying unit 2, and the outlet end of the air cooling and dehumidifying unit 2 is connected to the inlet end of the air compressor 3.

[0027] The air cooling and dehumidifying unit 2 has a built-in cooler that allows air to exchange heat with cold water, turning it into low-temperature gas. This gas then enters the baffle plate 22 and undergoes secondary separation with the dehumidifying filter membrane 23. This removes the water condensed in the air dehumidifier and the liquid droplets entrained in the air, thereby increasing the air volume entering the air compressor 3. The compressor is connected after the cooling and dehumidifying unit and is used to compress the gas into high-temperature, high-pressure gas.

[0028] like Figure 2As shown, the air cooling and dehumidifying device 2 includes a housing 21, a cooler, a baffle plate 22, and a dehumidifying filter membrane 23. The cooler is installed inside the housing 21, and the baffle plate 22 is installed at one end of the cooler. The dehumidifying filter membrane 23 is installed at the other end of the baffle plate 22. Two-stage separation is achieved through the baffle plate 22 and the dehumidifying filter membrane 23 of the air cooling and dehumidifying device.

[0029] The working principle of primary separation is as follows: When a gas containing liquid flows through the baffle plate 22 at a certain speed, due to the inertial impact of the gas, the droplets collide with the baffle plate 22 and are agglomerated. When the droplets become so large that their own gravity exceeds the resultant force of the gas's upward force and the liquid's surface tension, the droplets are separated from the surface of the baffle plate 22.

[0030] The baffle plate 22 has a curved channel, and it is detachably connected to the outer casing 21. Gas passes through the curved channel on the baffle plate 22, where, under the action of inertia and gravity, the liquid droplets entrained in the airflow are separated. The dehumidifying filter membrane 23 has membrane flow channels, which are obliquely arranged. The baffle plate 22 is an S-shaped baffle, horizontally arranged in the structure. The multi-bend structure of the baffle plate 22 increases the chance of mist capture; any unremoved mist droplets are captured again at the next bend due to the same action, and this repeated action greatly improves the demisting efficiency. After passing through the corrugated plate demister, most of the liquid droplets are filtered out. Gas passes through the curved channel of the demister, where, under the action of inertia and gravity, the liquid droplets entrained in the airflow are separated, thus achieving dehumidification.

[0031] The demisting efficiency of a demister increases with the increase of airflow velocity. This is because a higher flow velocity results in a greater inertial force acting on the droplets, which is beneficial for gas-liquid separation.

[0032] The working principle of the two-stage separation: The dehumidifying filter membrane 23 is made of plant fiber as the base material. It is sintered with resin of special components to form a corrugated plate-shaped cross-overlapping polymer composite material. It has the advantages of strong water absorption, self-cleaning ability, non-toxicity, acid and alkali resistance, mildew resistance and flame retardancy.

[0033] The dehumidifying filter membrane 23 is corrugated. The corrugated structure, with its numerous undulations and bends, significantly increases its profile length. This corrugated structure creates multiple layers and gaps, providing more space for contact. When other objects come into contact with the corrugated surface, they can penetrate into these gaps, increasing the number of contact points and the contact area. The corrugated structure of the dehumidifying filter membrane 23 provides the maximum contact area between air and its surface, offering 500–600 m² of contact area per square meter of membrane. The membrane flow channel is inclined at 45 degrees. When humidified air passes through the dehumidifying filter membrane 23, the moisture is fully absorbed by the membrane, thus achieving the purpose of drying the air.

[0034] The drain valve opens only when needed to discharge untransferred liquid water that has condensed on the feed side. After two-stage filtration, the water-gas separation efficiency is ≥95%, and the total resistance loss is less than 1 kPa.

[0035] An inspection ladder 24 is provided inside the outer casing 21, and the inspection ladder 24 is detachably connected to the outer casing 21. The inspection ladder 24 facilitates the maintenance of the air cooling and dehumidifying unit 2. An inspection door is provided in the middle of the outer casing 21. During maintenance, the operator enters through the inspection door and then enters the outer casing 21 through the inspection ladder 24 to perform the maintenance.

[0036] A protective net 25 is installed at one end of the dehumidifying filter membrane 23. The protective net 25 is located inside the outer casing 21 and is detachably connected to the outer casing 21. Its core function is to construct a filtration barrier, effectively intercepting solid pollutants with larger particle diameters in the environment. This protective net 25 can efficiently block larger impurities such as fallen leaves and suspended garbage fragments, thereby preventing such substances from directly entering the dehumidifier system, extending the equipment's lifespan, and ensuring the efficient and stable operation of the air purification process.

[0037] Air filter 1 and air cooling dehumidifier 2 are connected by a pipe, and a first valve 4 is installed on the pipe connecting air filter 1 and air cooling dehumidifier 2. Air cooling dehumidifier 2 and air compressor 3 are connected by a pipe, and a first valve 5 is installed on the pipe connecting air cooling dehumidifier 2 and air compressor 3.

[0038] A third valve 7 is installed at the lower end of the air cooling dehumidifier 2, and the third valve 7 is connected to the air cooling dehumidifier 2 via a pipe. A groove is provided below the baffle plate 22 and the dehumidifying filter membrane 23, and the third valve 7 is connected to the groove position of the air cooling dehumidifier 2. The third valve 7 is used to discharge liquid water that has not undergone mass transfer and has condensed on the feed side.

[0039] It also includes a fourth valve 6, one end of which is connected to the pipe at the inlet end of the air cooling and dehumidifying unit 2, and the other end of which is connected to the pipe at the outlet end of the air cooling and dehumidifying unit 2.

[0040] The first valve 4 is the inlet valve of the cooling and dehumidifying unit, the first valve 5 is the outlet valve, and the fourth valve 6 is the bypass valve. By closing the first valves 4 and 5 and opening the fourth valve 6, the cooling and dehumidifying unit can be shut off. This operation can be used to cut off the cooling and dehumidifying system in low-temperature winter environments, or during non-stop maintenance of the cooling and dehumidifying unit. Air passes directly through the air filter 1 into the air compressor 3 for production. The third valve 7 is connected to the cooling and dehumidifying unit's piping. Liquid water separated from the air in the cooling and dehumidifying system flows into a groove and out through the piping. The cooling and dehumidifying system is controlled by the third valve 7.

[0041] Chilled water enters the zone and flows through the zone's main valve and the dehumidifier's inlet valve into the dehumidifier. After heat exchange in the dehumidifier, it is discharged through the dehumidifier outlet valve, chilled water pump inlet valve, and outlet valve, and then sent to the chilled water heat exchange system via the zone's main outlet valve.

[0042] Working principle of air separation cooling and dehumidification device:

[0043] Open the first valve 4 and the first valve 5 of the air cooling and dehumidifying unit 2, and close the fourth valve 6.

[0044] When the air compressor 3 is started, air enters the air filter 1. The filtered air then enters the cooling and dehumidifying unit, and after heat exchange in the cooler, it enters the corrugated baffle 22 to eliminate mist.

[0045] After passing through the baffle 22, most of the liquid droplets are filtered out. As the gas passes through the tortuous channel on the baffle 22, the liquid droplets entrained in the gas flow are separated out under the action of inertial force and gravity.

[0046] The corrugated structure of the dehumidifying filter membrane 23 provides the maximum contact area between the air and its surface. When humid air passes through the dehumidifying filter membrane 23, the moisture is fully separated by the filter membrane, thereby achieving the purpose of dehumidification. The generated moisture is discharged through the third valve 7, and the air enters the compressor through the outlet for compression and utilization.

[0047] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
