Technical Field

[0001] This utility model relates to the field of fire protection and smoke exhaust technology for industrial plants, specifically to a smoke exhaust skylight that integrates air purification function and is suitable for smoke prevention and exhaust systems in industrial plants that generate polluting gases. Background Technology

[0002] Fire-fighting smoke extraction systems are crucial in industrial plants and public buildings. Traditional triangular smoke extraction skylights are primarily used for smoke extraction in emergencies such as fires, opening only when signaled by the fire control center. Their function is relatively simple, and they remain idle most of the time. However, industrial plants often generate large amounts of polluting or toxic gases during production. If these gases are not treated promptly, they can harm workers' health, reduce production efficiency, and pollute the atmosphere. Currently, common air purification equipment is installed independently from smoke extraction skylights. This not only leads to complex electrical wiring and high installation costs but also occupies a significant amount of building space, resulting in high equipment installation and maintenance costs. Utility Model Content

[0003] To address some of the problems existing in current smoke exhaust skylights, this utility model provides a smoke exhaust skylight with integrated air purification function. This solves the problems of limited functionality in existing smoke exhaust skylights, as well as the high cost and space occupation resulting from separate installation of air purification equipment and smoke exhaust skylights.

[0009] The purification duct is equipped with a filter component, a photocatalytic purification component, and an adsorption component.

[0010] Furthermore, from the air inlet to the exhaust fan, a filter assembly, a photocatalytic purification assembly, and an adsorption assembly are sequentially arranged.

[0011] Furthermore, the filter assembly, the photo-oxidation catalytic purification assembly, and the adsorption assembly are provided with inspection doors on their inner sides.

[0012] Furthermore, a U-shaped drainage ditch is formed in the middle of the top of the window frame, one end of the window sash is rotatably connected to the edge of the window frame, and the other end is inserted into the U-shaped drainage ditch.

[0013] Furthermore, the air inlet and exhaust fan are located on both sides of the window frame along its length.

[0014] Furthermore, an exhaust vent is provided on the window frame on the outside of the exhaust fan.

[0015] Furthermore, the adsorbent component in the adsorption assembly is activated carbon.

[0016] Furthermore, the top of the form frame is triangular.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: the smoke exhaust skylight of this application realizes the dual functions of fire smoke exhaust and air purification, and improves the practicality and functionality of smoke exhaust equipment in industrial plants.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-3 As shown, this embodiment provides a smoke exhaust skylight, including a window frame 1, a window sash 2 at the top of the window frame 1, one end of the window sash 2 being rotatably connected to the window frame 1, and a window opener 3 fixed on the window frame 1 below the window sash 2; the output end of the window opener 3 is connected to the window sash 2.

[0027] A purification chamber is provided on the window frame 1 at the lower end of window sash 2;

[0028] The cleanroom includes an exhaust fan 5, which is located on one side of the window frame 1;

[0029] The air inlet 7 is located on the window frame 1 on the other side of the exhaust fan 5. The air inlet 7 needs to have a certain length and width to ensure that indoor polluted air can quickly enter the air inlet 7.

[0030] The purification duct 8 is made of galvanized steel plate or galvanized iron plate and has a rectangular cross-section for easier installation and fixing. One end of the duct is connected to the air inlet 7 and the other end is connected to the exhaust fan 5. The purification duct 8 is arranged around the window frame 1, with space reserved for the exhaust fan 5, and then connected to the interfaces on both sides of the exhaust fan 5. In this embodiment, the purification duct 8 has an air inlet 7 on the side away from the exhaust fan 5, forming a whole with the purification duct 8 and the air inlet 7, reducing the use of connecting parts. The air inlet 7 is set vertically and faces the exhaust fan 5. The exhaust fan 5, the purification duct 8, and the air inlet 7 form a rectangular purification chamber.

[0031] The purification duct 8 is equipped with a filter component 9, a photocatalytic purification component 10, and an adsorption component 11. The filter component 9 mainly filters out large particles in the air, such as dust, PM2.5, and cooking fumes. The photocatalytic purification component 10 uses ultraviolet light of a specific wavelength to excite a catalyst, generating strong oxidizing free radicals that decompose organic pollutants into harmless substances such as carbon dioxide and water, thereby killing microorganisms and decomposing harmful gases. Ozone has strong oxidizing properties and can further react with organic matter to form a triple synergistic mechanism of "ultraviolet light-catalyst-ozone", which greatly improves purification efficiency. The adsorption component 11 uses materials with adsorption functions, such as activated carbon, to adsorb the remaining odors and chemical pollutants.

[0032] Connection lines are reserved for electrical control components such as exhaust fan 5, photocatalytic purification component 10, and window opener 3, and the wiring is uniform to facilitate power connection;

[0033] This smoke exhaust skylight is mainly used in fire smoke exhaust facilities in industrial plants. Under normal circumstances, the skylight is closed; when the fire control center sends a signal, the skylight can be opened quickly to exhaust smoke and meet fire protection requirements. At the same time, the purifier can run simultaneously to improve smoke exhaust efficiency and buy more escape time for people inside the room.

[0034] After the exhaust fan 5 is turned on, a negative pressure is formed in the purification duct 8, which draws indoor air in through the air inlet 7 and into the exhaust fan along the purification duct 8. The air flow direction is as shown by the arrow in the attached diagram. After being purified in the purification duct 8, the air is discharged into the air. This will not cause pollution to the natural environment. On the other hand, it is also beneficial to the physical and mental health of the staff, thereby improving production efficiency.

[0035] In another embodiment of this application, a filter assembly 9, a photocatalytic oxidation purification assembly 10, and an adsorption assembly 11 are sequentially arranged from the air inlet 7 to the exhaust fan 5. A certain distance is left between the filter assembly 9, the photocatalytic oxidation purification assembly 10, and the adsorption assembly 11, so that the polluted air is purified step by step to ensure emission standards.

[0036] In another embodiment of this application, the filter assembly 9, the photocatalytic purification assembly 10, and the adsorption assembly 11 are provided with inspection doors 12 on their inner sides to facilitate the inspection and replacement of each assembly.

[0037] In another embodiment of this application, the top of the window frame 1 is triangular, and a U-shaped drainage ditch 4 is formed in the middle of the top of the window frame 1. One end of the window sash 2 is rotatably connected to the outer side of the window frame 1 near the top, and the other end is inserted into the U-shaped drainage ditch 4 so that rainwater can flow down along the window sash 2 and the rainwater in the drainage ditch 4 can flow out from both ends.

[0038] In another embodiment of this application, the air inlet 7 and the exhaust fan 5 are arranged on both sides of the window frame 1 along its length, making it easier for indoor polluted air to enter the air inlet 7.

[0039] In another embodiment of this application, an exhaust port 6 is provided on the window frame 1 outside the exhaust fan 5, which can be opened and closed electrically, so that the exhaust fan 5 is isolated from the external environment when it is not in operation.

[0040] Working principle: Window sash 2 is controlled to open and close by window opener 3. Normally, it is mainly used for lighting to increase the illumination in the factory. When window opener 3 receives a fire signal, it will default to executing the fire command first, that is, opening window sash 2 and starting to execute the fire smoke exhaust function. At this time, the purification chamber fixed on the fire smoke exhaust skylight will also default to executing the opening command to help remove smoke and dust in the factory.

[0041] When polluted gas is generated in the factory, the purification chamber can be opened to start operation. After the exhaust fan 5 starts, the purification duct 8 generates negative pressure, and the polluted gas in the room is drawn into the purification duct 8 through the air inlet 7. The polluted air first enters the filter assembly 9, which removes dust, PM2.5, oil fumes, etc. The filtered semi-polluted gas enters the photocatalytic oxidation purification assembly 10. After passing through the UV lamp and catalyst, microorganisms are killed and harmful gases are decomposed. Then, the semi-clean gas enters the adsorption assembly 11, which adsorbs the remaining odors and chemical pollutants. Finally, the clean air is discharged outdoors by the fan 5. The purifier and the smoke exhaust skylight are designed and installed as an integrated structure. This integrated design reduces electrical wiring costs, saves space in the factory, and also reduces equipment installation costs.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
