Technical Field

[0001] This utility model relates to the technical field of air purification and ventilation, and in particular to the technical field of physical-electronic composite dust removal and purification fan box. Background Technology

[0002] In places with high air quality requirements, such as industrial plants, laboratories, and hospitals, it is usually necessary to use a combination of multiple purification technologies to treat the air. The existing common solution is to connect multiple independent devices such as electrostatic precipitators, photocatalytic oxidation equipment, bag filters, activated carbon adsorption boxes, and centrifugal fans in series through air ducts to form a purification system.

[0003] This traditional approach has significant drawbacks: First, the system occupies a large area, requiring dedicated space for layout and installation; second, complex piping connections not only increase installation costs but also lead to significant system air pressure loss and high energy consumption; third, multiple devices are controlled independently, resulting in poor coordination, scattered maintenance points, and inconvenient operation. Furthermore, traditional centrifugal fans mostly use belt drives, which have low transmission efficiency, a non-compact structure, and require regular belt maintenance and replacement, increasing operating costs.

[0004] Therefore, there is an urgent need for a composite purification and ventilation equipment that can overcome the above-mentioned shortcomings, integrate multiple functions, has a compact structure, is highly efficient and energy-saving, and is easy to maintain. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of large system footprint, high wind resistance loss, high energy consumption, and inconvenient maintenance caused by multiple devices connected in series in the existing technology. It proposes a physical-electronic composite dust removal and purification fan box, which innovatively integrates four purification technologies, namely electrostatic filtration, photocatalysis, medium-efficiency filtration, and adsorption filtration, with a high-efficiency direct-drive fan into a single box, achieving the beneficial effects of high purification efficiency, compact structure, low wind resistance, energy saving, low noise, and easy maintenance.

[0006] To achieve the above objectives, this utility model proposes a physical-electronic composite dust removal and purification fan box, including a fan box shell with an air inlet on one side and an air outlet on the other side. Its innovation lies in the following: Inside the fan box shell, along the airflow direction from the air inlet to the air outlet, are sequentially arranged an electrostatic filter, a photocatalytic generator, a photocatalytic carrier, a medium-efficiency filter, an activated carbon filter, and a fan unit; the fan unit includes a motor, an impeller, and a motor stand; the motor is fixed inside the fan box shell via the motor stand, and the motor's output shaft is coaxially and directly connected to the impeller; the impeller's outlet is connected to the air outlet; the fan box shell has an openable maintenance door corresponding to the position of the electrostatic filter.

[0007] Furthermore, the inspection door is connected to the fan housing via hinges and is equipped with a door handle and an operation nameplate for easy safe operation and maintenance.

[0008] Furthermore, the photocatalytic generator consists of multiple nanophotonic tubes arranged at equal intervals from top to bottom.

[0009] Furthermore, the photocatalytic support is a metal mesh or plate coated with nano-titanium dioxide catalyst.

[0010] Furthermore, the filter medium of the medium-efficiency filter has a continuous V-shaped structure to increase the filtration area; the filter medium of the activated carbon filter has a honeycomb structure to optimize adsorption efficiency and reduce air resistance.

[0011] Furthermore, it also includes a temperature gauge installed on the fan housing and a medium-efficiency differential pressure switch for monitoring the pressure difference across the medium-efficiency filter; the fan housing is also equipped with a controller and a working indicator light for displaying the system status. The controller is electrically connected to the medium-efficiency differential pressure switch, the working indicator light, the motor, and the photocatalytic generator to realize intelligent monitoring, alarm, and automatic control of the system.

[0012] Furthermore, the motor is a variable frequency motor, which can intelligently adjust the air volume and air pressure according to demand to achieve energy-saving operation.

[0013] Furthermore, the working indicator light is located on the inspection door.

[0014] Furthermore, both the air inlet and outlet have outwardly extending mounting flanges at their edges for easy connection to external air ducts; the bottom of the fan housing is provided with a mounting base with bolt holes for easy fixing of the equipment to the ground or a base.

[0015] The beneficial effects of this utility model are: 1. High-efficiency composite purification: Through a multi-stage combination of electrostatic filtration, photocatalytic oxidation, medium-efficiency filtration and activated carbon adsorption, it can effectively remove particulate matter, bacteria, viruses and gaseous pollutants from the air, with high purification efficiency.

[0016] 2. Extremely compact structure: Multiple functional modules are integrated into one box, and the direct drive of the motor and impeller eliminates the need for transmission components.

[0017] 3. Extremely convenient maintenance: The electrostatic filter unit, which requires the most maintenance, is equipped with an openable access door with operation indicators and indicator lights, making cleaning and maintenance simple and quick.

[0018] 4. High efficiency and energy saving: The direct drive fan has high transmission efficiency, low noise, and requires no maintenance; when combined with a variable frequency motor, it can deliver air on demand, resulting in significant energy savings.

[0019] 5. Intelligent monitoring: Through temperature gauges and medium-efficiency differential pressure switches, combined with controllers, the equipment operating status and filter clogging can be monitored in real time, and timely alarms can be triggered to prompt maintenance, thus achieving intelligent operation.

[0024] The working process of this utility model: The working process of this utility model's physical-electronic composite dust removal and purification fan box is explained in conjunction with the accompanying drawings.

[0025] The fan housing 1 is generally rectangular, with a horizontal dimension of 2300mm, a height of 1040mm (of which the bottom base is 80mm high and the upper main body is 960mm high), and a depth of 1140mm. The bottom of the fan housing 1 is provided with a mounting base 15, which has bolt holes 151 with a distance of 1080mm between the two sides, which can be used to fix the entire equipment to the ground or base with bolts.

[0026] The fan housing 1 has an air inlet 11 on its right side, with dimensions of 805mm in height and 865mm in depth. The fan housing 1 also has an air outlet 12 on its left side, with a rectangular cross-section, dimensions of 324mm in height and 234mm in depth. Both the air inlet 11 and the air outlet 12 have outwardly extending mounting flanges 14 along their edges. The airflow direction is horizontal intake and horizontal exhaust.

[0027] The following purification units are installed sequentially inside the fan housing along the airflow direction: Electrostatic filter 2: Located near the air inlet 11, it adsorbs larger particles and ionizes the air with high-voltage electrostatic discharge. The fan housing 1 has an access panel with a door 13 directly opposite this device. The door 13 is connected to the fan housing 1 via a hinge 131 and is equipped with a handle 132 for easy opening. An operation nameplate 133 and a work indicator light 134 are affixed to the outer surface of the door 13 for user safety and to monitor the equipment's operating status.

[0028] Photocatalytic generator 3: Located after the electrostatic filter 2, in the illustrated embodiment, it consists of four elliptical cross-section nanophotonic tubes arranged equidistantly from top to bottom, emitting ultraviolet light of a specific wavelength.

[0029] Photocatalytic carrier 4: Located after the photocatalytic generator 3, in the illustrated embodiment, it is a metal mesh or plate coated with nano-sized titanium dioxide catalyst, which generates highly oxidizing hydroxyl radicals under ultraviolet light irradiation, and is used to decompose organic pollutants and sterilize.

[0030] Medium-efficiency filter 5: Uses F6 grade filter media with a continuous V-shaped profile to increase the effective filtration area and extend service life. It is mainly used to capture smaller particles.

[0031] Activated carbon filter 6: Its filter media has a honeycomb structure with a large number of micropores, which are used to adsorb residual gaseous pollutants and odors after passing through the pre-treatment stage.

[0032] The fan unit 7 is located after all purification units. The fan unit 7 includes a motor 71, an impeller, and a motor mount 72. The motor 71 is securely mounted inside the fan housing 1 via the motor mount 72. The output shaft of the motor 71 is directly connected to the impeller coaxially. The impeller is a multi-blade centrifugal fan, and its outlet is connected to the air outlet 12 of the fan housing. After rotation, it discharges the purified air at high pressure. In this embodiment, the motor 71 is a 3kW, 380V / 3ph / 50Hz variable frequency motor, with an air volume Q reaching 2200m³ / h. 3 / h, wind pressure P can reach 1800Pa.

[0033] In addition, a thermometer is installed on the outer panel of the fan housing 1 to monitor the internal or ambient temperature. A medium-efficiency differential pressure switch is also installed, with its two ends connected to the inlet and outlet of the medium-efficiency filter 5, respectively, to detect the pressure difference across it. The fan housing is equipped with a controller (not shown in the figure), which can be installed inside the fan housing or in an external electrical control box. The controller is electrically connected to the medium-efficiency differential pressure switch, the working indicator light 134, the variable frequency motor 71, and the nanophoton tube 3. When the differential pressure switch detects that the filter resistance exceeds the limit, it sends a signal to the controller, which can trigger an alarm light to illuminate, indicating maintenance. The controller can also control the fan speed and the start / stop of the nanophoton tube according to a set program.

[0034] The working principle of this utility model is as follows: polluted air enters the box through the air inlet 11 and undergoes multiple purification processes, including electrostatic filtration, photocatalytic oxidation, medium-efficiency filtration, and activated carbon adsorption. Pollutants are removed step by step, and finally, the clean air is forcibly sent out from the air outlet 12 by the high-efficiency direct-drive fan unit 7.
