Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air purification and filtration, specifically a multi-layer composite air purification and filtration system for clean rooms. BACKGROUND

[0002] The multi-layer composite air purification and filtration system for clean rooms is composed of multiple filtration units, typically including a coarse filter, a medium filter, a high-efficiency filter, and an activated carbon adsorption layer, forming a hierarchical multi-purification structure. First, air passes through the coarse filter to remove large particulate matter such as dust and hair, reducing the burden on subsequent filters. Air passes through the high-efficiency filter to remove fine particles, bacteria, viruses, and other contaminants, ensuring clean air. Some systems also have an activated carbon adsorption layer to remove harmful gases and volatile organic compounds from the air. This multi-layer composite structure effectively filters various pollutants in the air, ensuring that the air quality in the clean room meets extremely high standards and meets the requirements of special environments.

[0003] Despite its excellent purification effect in clean room applications, the system has some drawbacks. The high air resistance caused by the high-efficiency filter and the fan requires a higher air flow rate, especially during long-term operation. The energy efficiency problem is particularly prominent, and the fan needs to provide stronger air flow to maintain air flow and filtration effect. This not only increases energy consumption, but excessive air resistance can affect air flow uniformity, leading to suboptimal air purification in some areas. SUMMARY

[0004] To address the shortcomings of the prior art, the present application provides a multi-layer composite air purification and filtration system for clean rooms, which solves the problem of air flow uniformity caused by the high-efficiency filter and the fan, leading to suboptimal air purification in some areas.

[0005] To achieve the above objectives, the present application is implemented by the following technical solutions: a multi-layer composite air purification and filtration system for clean rooms, comprising:

[0006] A base is provided with a lower support on which a plurality of air outlets are arranged. A collection box is fixed to the upper side of the base. A vibration rod is arranged inside the collection box. An air outlet pipe is arranged on the outer side of the lower support.

[0007] A filter housing is detachably connected to the inside of the lower support. A heating sheet is fixed inside the filter housing. A shape memory alloy adsorption grid is filled inside the heating sheet. A cavity is arranged inside the shape memory alloy adsorption grid. The upper end of the vibration rod is in contact with the cavity. A limiting piece is fixedly connected inside the filter housing. A second support is arranged inside the filter housing below the limiting piece. An installation slot is arranged inside the filter housing below the second support.

[0008] A power assembly is located inside the filter housing, and the power assembly comprises an air inlet mechanism, a motor and a first support frame, the air inlet mechanism is fixed with the filter housing, the motor is fixedly connected with the air inlet mechanism, and an output end of the motor is fixed with the first support frame;

[0009] The dynamic corrugated filter device comprises a support assembly and a filter assembly, the support assembly comprises a movable piece, a lower top cover, a sliding groove and a support rod, the support rod is fixed with the lower top cover, the sliding groove is located on the lower top cover, and the movable piece is sleeved on the sliding groove, the filter assembly comprises an upper top cover, an air inlet hole, a corrugated filter and an elastic ring, the air inlet hole is located on the upper top cover and extends to the inside of the corrugated filter, the lower side of the upper top cover is fixedly connected with the corrugated filter, the corrugated filter is of a corrugated shape, the lower side of the corrugated filter is fixedly connected with the elastic ring, and the elastic ring is sleeved on the movable piece.

[0010] Preferably, the side surface of the base is provided with a switch, and the base is provided with a power supply port.

[0011] Preferably, the upper side of the filter housing is provided with an upper side cover plate, a plurality of air inlet openings are arranged on the upper side cover plate, and the air inlet openings are arranged in an inclined distribution.

[0012] The application provides a clean room multi-layer composite air purification filtering system.

[0013] The clean room multi-layer composite air purification filtering system adopts a plurality of innovative structural designs, in addition to the dynamic corrugated filter device, further comprises a shape memory alloy adsorption grid, a vibration rod, a heating sheet and other core components, and further improves the filtering efficiency and system stability.

[0014] The shape memory alloy adsorption grid can automatically adjust the pore size according to the air quality change, and enhances the self-adaptive ability of the filter. When the concentration of pollutants in the air is high, the grid will expand to increase the filtering area, thereby improving the adsorption capacity; when the concentration of pollutants is low, the grid will shrink to reduce energy consumption and maintain smooth air flow. The vibration rod is used in cooperation with the adsorption grid for cleaning, and the heating sheet is combined with the grid to adjust the size of the cavity.

[0015] The cooperation of the air inlet mechanism and the motor can stabilize the air flow rate, avoid the problem of reduced filtering efficiency or poor local purification effect caused by too fast air speed. The support assembly can effectively support the corrugated filter, ensure that the filtering device maintains a stable state during operation, avoid air flow unevenness or unstable filtering effect caused by deformation or displacement of the filter, and the whole system cooperates through these designs, not only improves the air purification effect, but also enhances the durability and maintainability of the system.
