Abstract

Existing salt mist removal filtration methods struggle to meet the requirements of high air volume and low flow resistance, and none of them take into account silencing, requiring additional noise reduction measures to reduce the impact of noise on the surrounding environment. To overcome the shortcomings of existing technologies, the present invention proposes an ultra-high air volume, low flow resistance salt mist removal filtration device with silencing capabilities. This device, designed for cooling equipment with high ambient air volume requirements, such as air conditioners and liquid cooling sources, not only meets the high air volume salt mist filtration requirements of cooling equipment, but also provides silencing capabilities and facilitates maintenance.

Description

Technical Field

[0001] The present invention belongs to the field of electronic devices, and in particular relates to an ultra-high air volume, low flow resistance, desalination and mist filtering device with a silencing function. Background Art

[0002] Cooling equipment such as air conditioners and liquid cooling sources, which require high ambient air volume, are particularly vulnerable to salt spray when deployed in coastal areas, islands, or reefs. High levels of salt spray can cause corrosion of metal materials and accelerate the aging and strength loss of non-metallic materials. Failure to effectively remove the salt spray directly impacts the performance and reliability of these cooling equipment.

[0003] Salt mist removal filters filter salt mist particles from the air, providing suitable ambient air for cooling equipment. As electronic equipment generates increasing heat, cooling equipment like air conditioners and liquid cooling sources are increasingly demanding higher airflow volumes, placing even higher requirements on low flow resistance for salt mist removal devices. Furthermore, higher airflow not only increases airflow noise but also requires higher-powered fans, which generate even more noise during operation. This noise can severely impact the lives of workers and nearby residents, posing new requirements for noise reduction in salt mist removal devices.

[0004] Previous desalination mist filtration methods: 1. Physical filtration method. Due to the small salt mist particles, the porosity of the mesh / membrane used is usually very small, which cannot meet the needs of high air volume and low flow resistance. 2. Electrostatic desalination mist method has the characteristics of low flow resistance, but it cannot be used modularly and cannot be applied to occasions with large air volume requirements. 3. Previous desalination mist filtration methods did not consider the silencing function, and additional silencing measures were required to reduce the impact of noise on the surrounding environment.

DETAILED DESCRIPTION

[0028] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0029] like Figure 1 As shown, the desalination mist filtering device of the present invention includes a desalination mist filtering module 1 and a frame 2 .

[0030] like Figure 2 As shown, the desalination mist filtering module 1 includes a ventilation filter 3 and a power box 4.

[0031] like Figure 3 As shown, the ventilation filter 3 includes a ventilation duct 5, a first filter 6, a second filter 7 and a salt mist collector 8.

[0032] like Figure 4 As shown, the ventilation duct 5 includes a salt mist collector mounting groove 9 and a salt mist discharge hole 10.

[0033] like Figure 5 As shown, the first filter 6 is composed of an array of fins 11 , and each fin 11 has a separation blade 12 .

[0034] like Figure 6 As shown, the second filter 7 is composed of a positive electrode and a negative electrode array. The positive electrode includes a discharge positive electrode 13 and a baffle 14 , and the negative electrode includes a discharge negative electrode 15 and a sound absorbing plate 16 .

[0035] like Figure 8 As shown, the power box 4 includes a power box housing 17 and a high-voltage power supply 18.

[0036] The sound absorbing panel 16 adopts a sound absorbing superstructure design, and the sound absorbing superstructure is designed based on superstructure siphon effect sound absorption technology and superstructure multi-order resonance sound absorption technology.

[0037] Several desalination filter modules 1 are mounted on a frame 2. A first filter 6 is mounted inside the ventilation duct 5, near the air inlet. A second filter 7 is mounted inside the ventilation duct 5, near the air outlet. A salt mist collector 8 is mounted in a salt mist collector mounting slot 9 in the ventilation duct 5. A high-voltage power supply 18 is mounted in a power supply housing 17.

[0038] The salt mist removal function of the present invention is achieved as follows: air carrying a large amount of salt mist particles first passes through the first filter 6 at an appropriate wind speed. Since the fins 11 are equipped with separation blades 12, due to the inertial impact and surface tension, part of the salt mist in the airflow gathers on the separation blades 12, thereby achieving partial filtration of the salt mist. Then it passes through the second filter 7. The second filter 7 is powered by a high-voltage power supply 18. A strong electric field exists between the discharge positive electrode 13 and the discharge negative electrode 15 of the second filter 7. The strong electric field ionizes the surrounding gas, forming a large number of positive ions and free electrons. The free electrons drift toward the discharge positive electrode 13 with the electric field and collide with neutral salt mist particles. The negatively charged salt mist particles move toward the discharge positive electrode 13 under the action of the electric field until they are adsorbed. A baffle 14 is installed at the end of the discharge positive electrode 13 near the air outlet. The baffle 14 can prevent the adsorbed salt mist particles from escaping from the discharge positive electrode 13 under the action of wind. A salt mist discharge hole 10 is opened in the ventilation duct 5. The salt mist particles collected and adsorbed by the first filter 6 and the second filter 7 are deposited under the action of gravity and collected into the salt mist collector 8 through the salt mist discharge hole 10. During maintenance, the salt mist collector 8 is pulled out from the salt mist collector installation slot 9 and cleaned.

[0039] The present invention achieves its noise reduction function by arranging the fins 11 of the first filter 6 in an array, and the positive discharge electrode 13, baffle 14, negative discharge electrode 15, and sound-absorbing panels 16 of the second filter 7 in an array. This arrangement stabilizes the flow of air and reduces aerodynamic noise. The sound-absorbing panels 16 utilize a sound-absorbing superstructure design and are installed in an array within the ventilation duct 5, effectively silencing noise from equipment such as fans.

[0040] The present invention is not limited to the above specific embodiments, and various modifications and variations are possible. Any modification, equivalent replacement, improvement, etc. made to the above embodiments based on the technical essence of the present invention shall be included in the scope of protection of the present invention.
