Description

Technical Field

[0001] The invention provides an indoor air purification and waste heat recovery device for antique buildings using solar energy photocatalysis, and relates to the technical field of air purification and waste heat recovery. Background Art

[0002] With the continuous improvement of people's cultural needs, especially in the context of the revival of traditional culture, the demand for antique buildings has gradually increased. In the past, many ancient buildings suffered serious damage, which prompted the need for reconstruction and restoration of antique buildings. In addition, the launch of popular games such as "Black Myth: Wukong" has also stimulated people's interest in traditional culture and the style of ancient buildings, further promoting the craze for antique buildings. However, newly built antique buildings are often accompanied by a heavy smell of paint, especially when modern decoration materials are used, which causes many visitors to feel dizzy, nauseous and other discomfort when visiting. Therefore, in the construction process of antique buildings, effective air purification measures must be taken to ensure the comfort of visitors. However, if the air purification device is directly installed on the outside of the building, it may destroy its overall ancient atmosphere and beauty. Therefore, it is particularly important to adopt a hidden installation method for purification equipment. By cleverly hiding the purification equipment inside the building or in an inconspicuous position, it can not only avoid affecting the appearance, but also effectively improve the air quality, ensuring that visitors can have a better visiting experience while enjoying the beauty of cultural heritage.

[0003] Some existing patents have proposed some antique building air purification technologies and their applications, such as patent CN221442004U discloses a ventilated building structure with an antique building design, the main feature of which is that the middle part of the roof is provided with several through holes, and each is provided with a fixed tube, the lower part of the several fixed tubes is provided with several support plates, and several support plates are provided with electric telescopic rods, and each is electrically connected to an external power supply through wires, and the upper part of the several electric telescopic rods is provided with lifting columns, and several lifting columns are provided with several air guide grooves around them. Although this implementation method contributes to the overall aesthetics of the antique building, the overall structure is complex, the ventilation effect is not ideal, the air purification effect is poor, and the release period of harmful substances such as formaldehyde cannot be significantly shortened. Patent CN219060314U discloses a new type of antique building for energy saving and emission reduction, the main feature of which is that a ventilation device is provided on both side end faces of the ridge of the antique building, a ventilation fan is installed inside the ventilation device, and grid plates are provided on both sides of the ventilation fan. Although this implementation method helps to improve the freshness of indoor air and has low installation and maintenance costs, it mainly relies on the introduction of outside air to remove harmful substances. If the quality of external air is not good, the use of ventilation fans may not significantly improve the indoor air quality and may even bring more pollution. For some chemicals, such as formaldehyde and other harmful gases or bacteria, relying solely on the ventilation effect of ventilation fans cannot effectively remove them.

[0004] The present invention provides an indoor air purification and waste heat recovery device for antique buildings using solar photocatalysis, which cleverly integrates the air purification system with the antique buildings to avoid external exposure, and can not only maintain the traditional style and beauty of the antique buildings, but also effectively remove harmful substances without destroying the overall building structure and atmosphere. In the photocatalytic process, solar energy is used as a light source, and sunlight can be directly converted into chemical energy, with high energy utilization efficiency. The cost of photocatalysis is low, and no harmful substances are generated during use. By recovering and utilizing waste heat, the energy consumption of antique buildings can be significantly reduced, which is in line with the concept of green buildings. Summary of the invention

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] As attached Figure 1 As shown, the indoor air purification and waste heat recovery device for antique buildings using solar photocatalysis has a system working process as follows: the indoor air of the antique building enters the hollow column 1 through the cold air inlet 2-1 at the lower end of the hollow column 1 under the action of the induced draft fan 8 installed between the hot air outlet 2-2 and the evaporation section inlet 9-1-1, and fully contacts with the photocatalytic coating 3 on the inner wall surface of the hollow column 1. When there is sufficient sunlight, the ultraviolet lamp 4 is turned off, and the sunlight is irradiated on the photocatalytic coating 3 through the transparent skylight 6. At this time, the photocatalytic coating 3 converts light energy into chemical energy, giving the surface of the photocatalytic coating 3 a strong oxidizing ability, which can oxidize and decompose formaldehyde and various toxic substances produced by the paint in the antique building, and convert them into harmless substances, thereby achieving the purpose of purifying the air. When there is insufficient sunlight, the ultraviolet lamp 4 is turned on, and sunlight and ultraviolet light are irradiated on the photocatalytic coating 3 together. At this time, the photocatalytic coating 3 converts light energy into chemical energy, giving the surface of the photocatalytic coating 3 a strong oxidizing ability, which can oxidize and decompose formaldehyde and various toxic substances produced by paint in antique buildings, and convert them into harmless substances, thereby achieving the purpose of purifying the air.

[0027] The hot air after photocatalysis flows into the heat pipe heat exchanger 9 through the air inlet duct 12-1 under the action of the induced draft fan 8. When the evaporation section 9-1 in the heat pipe heat exchanger 9 is heated, the water in the pipe evaporates and vaporizes. The steam flows to the condensation section 9-2 under a small pressure and releases heat to condense into liquid. Under the action of gravity, it flows back to the evaporation section. In this cycle, the heat is transferred from the evaporation section 9-1 to the condensation section 9-2. The high-temperature air exchanges heat and cools down in the heat pipe heat exchanger 9, and then flows back to the room through the exhaust duct 13, promoting the indoor air purification cycle.

[0028] Cold water flows to the condensation section 9-2 through the first connecting water pipe 14-1 under the action of the first water pump 13-1, and the condensation section 9-2 releases the heat conducted by the evaporation section 9-1 to heat the water and then flows to the hot water storage tank 10. When the hot water terminal 11 needs to use hot water, the second water pump 13-2 is turned on, and under the action of the second water pump 13-2, the hot water in the hot water storage tank 10 is supplied to the hot water terminal 11 through the second connecting water pipe 14-2. When the hot water terminal 11 does not need to use hot water, the second water pump 13-2 is turned off, and the hot water is stored in the hot water storage tank 10. The outer surface of the hot water storage tank 10 is wrapped with a heat-insulating material to reduce heat loss.
