Description

A small environmental air cleaning system for cultural relics coupled with solid-state fan adsorption and purification

technical field

The utility model relates to the field of air purification, in particular to a small environmental air cleaning system for cultural relics coupled with a solid-state fan for adsorption and purification, which is mainly used for air purification in display cabinets and storage cabinets for cultural relics.

Background technique

The air quality of the preservation environment of cultural relics is an important limiting factor for the life of cultural relics, and the preservation of cultural relics in national and provincial museums in my country is generally based on the preservation of showcases. The main parameters affecting the preservation environment of cultural relics are ambient temperature, humidity, inappropriate lighting and air pollution. Among them, gaseous air pollutants have a great impact on cultural relics, and the commonly used method to remove gaseous pollutants is adsorption purification.

The Chinese patent document with the application number 201610078952.4 discloses an air purifier, in which a primary fan, an air tray, a filter layer, an activated carbon layer and a photocatalyst layer are sequentially installed in the filter cavity, and several through holes are uniformly arranged on the air tray, The activated carbon layer is arranged in an arc shape, and its arc-shaped concave side faces the filter layer. The design of the invention is reasonable, the air entering the filter chamber can be uniformly passed through the filter layer through the arrangement of the air disc, and the adsorption area can be increased through the arc-shaped arrangement of the activated carbon layer, so that the purification effect is improved.

As in the above example, currently commonly used air purifiers are mainly composed of motors, fans, air filters and other systems. Absorb and remove various pollutants. However, such a system driven by a mechanical fan has relatively large vibration and noise, and due to structural limitations, miniaturization is very difficult. In response to this problem, solid-state fans have gradually been paid attention to as driving devices instead of mechanical fans.

The Chinese patent document with the application number 201510811961.5 discloses a solid-state fan coupled semiconductor constant temperature and humidity display cabinet for cultural relics, including a cabinet body, a constant temperature and humidity unit, and a gas delivery unit. The constant temperature and humidity gas generated by the wet unit includes the air duct connecting the cabinet and the constant temperature and humidity unit, the first solid-state fan that provides gas circulation power, and the driving power supply; the gas transmission device of the present invention uses a solid-state fan to achieve The accelerated flow of gas can provide power for gas transmission, which overcomes the problems of noise, vibration and high energy consumption of traditional mechanical fans, and has the advantages of low energy consumption, no noise and vibration, and easy control.

To sum up, it can be seen that the removal of gaseous pollutants is very important for the preservation of cultural relics. The traditional mechanical fan drive system has many shortcomings. The system that replaces the mechanical fan with a solid-state fan is very suitable for small air treatment systems. Therefore, the solid-state fan can be used in conjunction with the adsorption purification device to effectively purify the air for the cultural relics display cabinet.
