New energy building environment air purification device

Abstract

This utility model provides a new energy building environment air purification device, belonging to the field of air purification. It includes a purification box, inside which a dust removal component for filtering and removing dust from the gas is fixedly installed. The purification box also contains a filter component for multiple filtration of the gas. When a fan draws dust-laden gas into the purification box, the gas is filtered through filter bags, and dust is trapped on the surface of the filter bags. As dust accumulates on the surface of the filter bags, a pressure sensor detects a pressure difference change, and the controller activates the electromagnetic pulse valve. This causes compressed air from the pulse air chamber to be sprayed at high speed through a jet pipe and jet plate towards the inside of the filter bags. The instantaneous reverse airflow causes the filter bags to shake violently, removing surface dust. The dislodged dust falls into a collection frame, and the purified gas is discharged through the purification hole. The reinforced frame prevents deformation or damage due to airflow impact during pulse jet cleaning.

Description

Technical Field

[0001] This utility model relates to the field of air purification, and more specifically, to a new energy building environment air purification device. Background Technology

[0002] The development of new energy building environment air purification devices is driven by air pollution, policy guidance, upgrading consumer demand, and cross-integration of technologies. Its technological evolution has gone through four generations: early physical filtration initially purified particulate matter; adsorption and electrostatic technologies improved efficiency but had the risk of secondary pollution; catalytic decomposition technology achieved chemical purification of pollutants; and the current intelligent active purification technology integrates AI, sensing, and new energy to achieve efficient, precise, and low-energy operation. In the future, the device will continue to optimize its performance through the application of new materials and deeply penetrate into scenarios such as homes, vehicles, and industries.

This utility model has a reasonable structural design, is easy to move, has an adjustable height, and is easy to install and remove, which can improve the air purification effect of the building environment, avoid the fine filter clogging affecting the purification effect, and is more practical." However, it still has the following defects:

[0004] (1) In actual use, the device relies only on physical interception, has low filtration efficiency for fine particles such as PM2.5, cannot perform deep air cleaning, and the wind resistance increases after long-term use, requiring frequent replacement.

[0005] In practical use, this device lacks a regeneration or replacement reminder function, and may release adsorbed pollutants after saturation, causing secondary pollution. Therefore, a new energy building environment air purification device is proposed. Utility Model Content

[0006] The purpose of this invention is to address the problems of existing devices that rely solely on physical interception, have low filtration efficiency for fine particles such as PM2.5, cannot perform deep air cleaning, and experience increased wind resistance after long-term use, requiring frequent replacement; these devices also lack regeneration or replacement reminder functions and may release adsorbed pollutants after saturation, causing secondary pollution. This invention provides a new energy building environment air purification device to solve the problems mentioned in the background technology.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] The present invention is as follows: a new energy building environment air purification device, including a purification box, wherein a dust removal component for filtering and removing dust from the gas is fixedly installed inside the purification box, and a filter component for multiple filtration of the gas is provided inside the purification box.

[0009] The dust removal assembly includes a fan fixedly installed on one side of the purification chamber, the fan's outlet communicating with the purification chamber, a placement plate fixedly installed on one side of the purification chamber, a pulse air manifold fixedly installed on the top of the placement plate, an electromagnetic pulse valve connected to the outlet of the pulse air manifold, a blowpipe fixedly installed at the outlet of the electromagnetic pulse valve, an air jet plate connected to the blowpipe, a filter bag inserted into the top of the purification chamber, a pressure sensor fixedly installed on one side of the purification chamber, a controller mounted on the pressure sensor, a reinforcing frame fixedly installed on the side of the filter bag away from the top of the purification chamber, a storage frame fixedly installed at the bottom of the reinforcing frame, and multiple purification holes opened on one side of the purification chamber.

[0010] As a preferred technical solution of this utility model, the filtration assembly includes a HEPA filter that is slidably installed inside the purification box, two photocatalytic filters that are slidably installed inside the purification box, a UV lamp plate that is slidably installed between the two photocatalytic filters, a photosensitive sensor that is fixedly installed on the top of the purification box and works in conjunction with the UV lamp plate, four activated carbon filters that are slidably installed inside the purification box, and a washable filter that is fixedly installed at the bottom of the purification box and located at the purification hole.

[0011] As a preferred technical solution of this utility model, a solar panel is fixedly installed on the top of the purification box, and a storage battery is fixedly installed on the inner top of the purification box. The storage battery and the solar panel are connected together by wires.

[0012] As a preferred technical solution of this utility model, an inspection door is hinged to one side of the purification box, a rubber strip is fixedly installed on the inner edge of the inspection door, and a mechanical lock is fixedly installed on one side of the inspection door.

[0013] As a preferred technical solution of this utility model, a drawer is slidably installed on one side of the storage frame, and a fireproof plate is provided at the bottom of the drawer.

[0014] As a preferred technical solution of this utility model, an air quality sensor is fixedly installed inside the purification box, and a control panel is fixedly installed on one side of the purification box. The control panel is used in conjunction with the air quality sensor, and the control panel integrates a smart display, control buttons and an alarm.

[0015] As a preferred technical solution of this utility model, a protective door is hinged to one side of the purification box, and the protective door is located above the control panel.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By setting up a dust removal component, when the dust removal component is working, the fan draws dust-laden gas into the purification chamber. After the gas is filtered by the filter bag, the dust is trapped on the surface of the filter bag. As the dust accumulates on the surface of the filter bag, the pressure sensor detects a change in pressure difference, and the controller starts to activate the electromagnetic pulse valve. The compressed air in the pulse air tank is then sprayed at high speed through the jet pipe and jet plate to the inside of the filter bag. The instantaneous reverse airflow causes the filter bag to shake violently to remove the surface dust. The detached dust falls into the storage box at the bottom of the reinforcing frame, and the purified gas is discharged through the purification hole. The reinforcing frame is fixed on the side of the filter bag away from the top of the purification chamber, which can provide structural support for the filter bag and prevent it from being deformed or damaged by the airflow impact during pulse jet cleaning.

[0018] 2. By setting up a filtration system, the gas filtered through the filter bags continues to flow into the core area of ​​the purification chamber during use. The HEPA filter can efficiently capture PM2.5, pollen, and other fine particulate matter, with a filtration efficiency of 99.97%. The gas then enters the photocatalytic reaction zone, where the UV lamp panel automatically adjusts its brightness under the monitoring of a photosensitive sensor, ensuring both light intensity and avoiding energy waste. Ultraviolet light activates the nano-scale titanium dioxide coating on the surface of the photocatalytic filter, generating strong oxidizing free radicals that decompose gaseous pollutants such as formaldehyde and benzene compounds. At the same time, it destroys the DNA structure of bacteria and viruses to achieve sterilization and disinfection. Then, when the air passes through four layers of activated carbon filters, the activated carbon filters can adsorb odor molecules such as hydrogen sulfide and ammonia. Finally, the gas undergoes final filtration through a washable filter, and the clean air after multiple purifications is discharged from the purification port. The sliding installation design of each filter facilitates quick replacement and maintenance, ensuring continuous and efficient purification. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0029] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0030] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] like Figure 1 As shown, this embodiment proposes a new energy building environment air purification device, including a purification box 1, a dust removal component 2 for filtering and removing dust from the gas is fixedly installed inside the purification box 1, and a filter component 3 for multiple filtration of the gas is provided inside the purification box 1.

[0033] like Figure 3 and Figure 8As shown, the dust removal assembly 2 includes a fan 201 fixedly installed on one side of the purification chamber 1, with the fan 201's outlet communicating with the purification chamber 1. A placement plate 202 is fixedly installed on one side of the purification chamber 1, and a pulse air manifold 203 is fixedly installed on the top of the placement plate 202. An electromagnetic pulse valve 204 is connected to the outlet of the pulse air manifold 203, and a blowpipe 205 is fixedly installed at the outlet of the electromagnetic pulse valve 204. A blowpipe 206 is connected to the blowpipe 205. A filter bag 207 is inserted and installed inside the top of the purification chamber 1. A pressure sensor 208 is fixedly installed on one side of the purification chamber 1, and a controller 209 is installed on the pressure sensor 208. The pressure sensor 208 monitors the resistance of the filter bag 207 in real time, and the controller 209 automatically controls the pulse cleaning frequency to achieve continuous dust removal and filter bag 207 regeneration. A reinforcing frame 210 is fixedly installed on the side of the filter bag 207 away from the top of the purification chamber 1. The reinforcing frame 210 can prevent the filter bag 207 from deforming. A storage frame 211 is fixedly installed at the bottom of the purification box 1. Multiple purification holes 212 are opened on one side of the purification box 1. When the dust removal component 2 is working, the fan 201 draws dust-laden gas into the purification box 1. After the gas is filtered by the filter bag 207, the dust is trapped on the surface of the filter bag 207. As the dust accumulates on the surface of the filter bag 207, the pressure sensor 208 detects a change in pressure difference, and the controller 209 starts to activate the electromagnetic pulse valve 204, so that the compressed air in the pulse air tank 203 passes through the pressure sensor 208. The jet pipe 205 sprays high-speed air onto the inside of the filter bag 207 via the jet plate 206. The instantaneous reverse airflow causes the filter bag 207 to shake violently to remove surface dust. The detached dust falls into the storage frame 211 at the bottom of the reinforcing frame 210. The purified gas is then discharged through the purification hole 212. The reinforcing frame 210 is fixed to the side of the filter bag 207 away from the top of the purification box 1, which can provide structural support for the filter bag 207 and prevent it from being deformed or damaged by the airflow impact during pulse jet cleaning.

[0034] like Figure 4 and Figure 8As shown, the filter assembly 3 includes a HEPA filter 301 slidably installed inside the purification chamber 1, two photocatalytic filters 302 slidably installed inside the purification chamber 1, and a UV lamp plate 303 slidably installed between the two photocatalytic filters 302. A photosensitive sensor 304 is fixedly installed on the top of the purification chamber 1. The photosensitive sensor 304 works in conjunction with the UV lamp plate 303. Under the ultraviolet irradiation of the UV lamp plate 303, the photocatalytic filters 302 generate highly oxidizing hydroxyl radicals and reactive oxygen species, which can decompose harmful gases such as formaldehyde and benzene into harmless substances, and also have a sterilization function. Four activated carbon filters 305 are slidably installed inside the purification chamber 1. A washable filter 306 is fixedly installed at the bottom of the purification chamber 1 and located at the purification hole 212. The washable filter 306 is not only environmentally friendly and economical, but also highly efficient in filtration. During use, the gas filtered by the filter bag 207 continues to flow into the purification chamber. Entering the core area of ​​the purification chamber 1, the HEPA filter 301 efficiently captures PM2.5, pollen, and other fine particulate matter, achieving a filtration efficiency of 99.97%. The gas then enters the photocatalytic reaction zone, where the UV lamp panel 303 automatically adjusts its brightness under the monitoring of the photosensitive sensor 304, ensuring both light intensity and avoiding energy waste. Ultraviolet light activates the nano-scale titanium dioxide coating on the surface of the photocatalytic filter 302, generating highly oxidizing free radicals that decompose gaseous pollutants such as formaldehyde and benzene compounds. Simultaneously, it destroys the DNA structure of bacteria and viruses, achieving sterilization and disinfection. Then, as the air passes through the four-layer activated carbon filter 305, the activated carbon filter 305 adsorbs odor molecules such as hydrogen sulfide and ammonia. Finally, the gas undergoes final filtration through the washable filter 306, and the clean air, after multiple purification processes, is discharged from the purification port 212. The sliding installation design of each filter facilitates quick replacement and maintenance, ensuring continuous and efficient purification.

[0035] As shown in the figure Figure 5 As shown, a solar panel 4 is fixedly installed on the top of the purification box 1, and a storage battery 5 is fixedly installed on the inner top of the purification box 1. The storage battery 5 and the solar panel 4 are connected together by wires. When in use, the solar panel 4 on the top of the purification box 1 converts solar energy into electrical energy, which is stored in the storage battery 5 on the inner top through wires to form an independent power supply system. The storage battery 5 stores electricity when there is sufficient sunlight, and supplies power to components such as the fan 201 and UV lamp panel 303 at night or on cloudy days to ensure continuous operation.

[0036] like Figure 5 and Figure 7 As shown, a maintenance door 6 is hinged to one side of the purification chamber 1. A rubber strip 7 is fixedly installed on the inner edge of the maintenance door 6. A mechanical lock 8 is fixedly installed on one side of the maintenance door 6. A hidden handle is provided on one side of the maintenance door 6. When using the maintenance door 6 of the purification chamber 1, the user can open the mechanical lock 8 through the hidden handle and push open the hinged maintenance door 6 to perform internal maintenance. When the door is closed, the rubber strip 7 fits tightly against the chamber body to ensure airtightness and prevent air leakage.

[0037] like Figure 6 As shown, a drawer 9 is slidably installed on one side of the storage frame 211. A fireproof plate 10 is installed at the bottom of the drawer 9. When in use, the drawer 9 of the storage frame 211 is pushed and pulled by the slide rail, which makes it easy to clean the dust of the filter bag 207. The fireproof plate 10 at the bottom is made of high temperature resistant material, which can block sparks and prevent dust from smoldering, ensuring safety. This design integrates dust collection and fire prevention functions, ensuring the safe operation of the system, while simplifying the maintenance process.

[0038] like Figure 5 and Figure 6 As shown, an air quality sensor 11 is fixedly installed inside the purification box 1, and a control panel 12 is fixedly installed on one side of the purification box 1. The control panel 12 works in conjunction with the air quality sensor 11. The control panel 12 integrates a smart display 13, control buttons 14, and an alarm 15. During use, the air quality sensor 11 of the purification box 1 monitors parameters such as PM2.5 and TVOC in real time. It converts particulate matter concentration into electrical signals through laser scattering or infrared principles, and transmits them to the control panel 12 after algorithm processing. The smart display 13 of the control panel 12 presents the air quality data intuitively in digital or light form, and supports historical record query and filter life reminder. Users can switch between automatic / manual modes, adjust the fan speed (low / medium / high speed), or set a timer function through the control button 14. When the air quality sensor 11 detects that the air quality exceeds the standard, the filter is saturated, or the equipment malfunctions, the alarm 15 will sound an alarm to prompt the user to take measures.

[0039] like Figure 6 As shown, a protective door 16 is hinged to one side of the purification box 1. The protective door 16 is located above the control panel 12. A handle is fixedly installed on one side of the protective door 16. When in use, the protective door 16 is made of high-strength plastic material. The protective door 16 is opened and closed smoothly through the hinge. Users can easily operate it through the side handle. Its core function is to protect the control panel 12 and the internal air quality sensor 11 from physical collisions, dust intrusion, or moisture corrosion.

[0040] Specifically, when this new energy building environment air purification device is in use: when the dust removal component 2 is working, the fan 201 draws dust-laden gas into the purification chamber 1. After the gas is filtered by the filter bag 207, the dust is trapped on the surface of the filter bag 207. As the dust accumulates on the surface of the filter bag 207, the pressure sensor 208 detects a change in pressure difference, and the controller 209 starts the electromagnetic pulse valve 204. The compressed air in the pulse air tank 203 is then sprayed at high speed through the blow pipe 205 and the jet plate 206 towards the inside of the filter bag 207. The instantaneous reverse airflow causes the filter bag 207 to shake violently to remove the surface dust. The detached dust falls into the collection frame 211 at the bottom of the reinforcing frame 210, and the purified gas is discharged through the purification hole 212. The reinforcing frame 210 is fixed on the side of the filter bag 207 away from the top of the purification chamber 1, providing structural support for the filter bag 207 and preventing it from deforming or breaking due to airflow impact during pulse blowing. The filtered gas continues to flow into the core area of ​​the purification chamber 1. The HEPA filter 301 can efficiently capture PM2.5, pollen and other fine particulate matter, with a filtration efficiency of 99.97%. The gas then enters the photocatalytic reaction zone. The UV lamp panel 303 automatically adjusts its brightness under the monitoring of the photosensitive sensor 304, ensuring both light intensity and avoiding energy waste. The ultraviolet light activates the nano-scale titanium dioxide coating on the surface of the photocatalytic filter 302, generating strong oxidizing free radicals to decompose gaseous pollutants such as formaldehyde and benzene series compounds. At the same time, it destroys the DNA structure of bacteria and viruses to achieve sterilization and disinfection. Then, when the air passes through the four-layer activated carbon filter 305, the activated carbon filter 305 can adsorb odor molecules such as hydrogen sulfide and ammonia. Finally, the gas undergoes final filtration through the washable filter 306. The clean air after multiple purifications is discharged from the purification hole 212. The sliding installation design of each filter facilitates quick replacement and maintenance, ensuring continuous and efficient purification.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
