Description

Technical Field

[0001] This utility model relates to the field of residential building flue technology, and in particular to an electrostatic integrated machine for public flues in residential buildings. Background Technology

[0002] With the acceleration of urbanization, centralized smoke exhaust systems (public smoke ducts) in high-rise residential buildings have become standard equipment. Conventional public smoke ducts mostly use mechanical filters to trap oil fume particles. However, they have some shortcomings in long-term operation: First, the filters have limited ability to trap oil fume particles. A large number of grease particles enter the inner wall of the smoke duct with the airflow and continue to accumulate, forming flammable oil sludge. This not only blocks the air duct and increases the smoke exhaust resistance, but also poses a serious fire hazard. Second, there is a lack of effective oil sludge guiding and collection structures. Oil droplets are easy to remain or drip inside the equipment, leading to secondary pollution. Frequent manual cleaning is also required, resulting in high maintenance costs.

[0003] Therefore, there is an urgent need for an integrated solution that combines high-efficiency purification, automatic oil collection, and convenient maintenance. In particular, it is necessary to overcome the bottleneck of insufficient synergy between existing electric field purification units and oil collection systems, achieving a closed-loop treatment of oil fume particles through adsorption, diversion, and collection. This would eliminate the risk of oil buildup and improve the safety and sustainability of public flues. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the problems with the electrostatic generator used in the public flue of residential buildings, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an electrostatic integrated machine for public flues in residential buildings, which is used to solve problems such as "grease particles enter the flue wall with the airflow and continuously accumulate, forming flammable oil scale, which not only blocks the air duct and increases the smoke exhaust resistance, but also poses a serious fire hazard".

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an electrostatic integrated machine for public flue gas ducts in residential buildings, comprising: a cabinet, and an electric field unit fixedly installed in the cabinet, wherein the electric field unit is used to adsorb and purify oil fume particles;

[0008] The fan mechanism located inside the cabinet includes a dual-inlet centrifugal fan, which provides power for the extraction of oil fumes.

[0009] A waste oil collection mechanism is provided inside the cabinet, the waste oil collection mechanism including an oil screen and an oil receiving tray;

[0010] The electric field unit, in conjunction with the oil mesh, collects the e-liquid into the oil receiving tray.

[0011] As a preferred embodiment of the electrostatic precipitator for public flue gas ducts in residential buildings described in this utility model, the dual-inlet centrifugal fan includes a fan body fixedly installed on the inner wall of the cabinet, the dual-inlet centrifugal fan has two fan inlets, the output end of the dual-inlet centrifugal fan is fixedly provided with a silencer duct, and the outlet is provided with a fan outlet.

[0012] As a preferred embodiment of the electrostatic integrated machine for public flue gas ducts in residential buildings described in this utility model, the fan mechanism further includes an electrical control box for providing power and control to the device.

[0016] As a preferred embodiment of the electrostatic precipitator for public flue gas ducts in residential buildings described in this utility model, wherein: a top cover is fixedly provided on the top cover, and sound-absorbing cotton is adhered inside the top cover.

[0017] As a preferred embodiment of the electrostatic precipitator for public flue gas ducts in residential buildings described in this utility model, the front side of the cabinet is provided with a fan box door panel and an electrostatic purification box door panel.

[0018] The beneficial effects of this utility model are as follows: Oily fumes enter the equipment through the oil fume inlet and then through the oil mesh. The specially structured oil mesh can allow fumes to pass through but not liquids. When the fumes pass through the oil mesh, large oil fume particles are partially intercepted by the oil mesh through collision, detour, acceleration, and deceleration.

[0030] Example 1

[0031] Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides an electrostatic integrated machine for public flue gas ducts in residential buildings, which can achieve efficient purification and automatic oil collection. It includes: a cabinet 100, an electric field unit 300 fixedly installed in the cabinet 100, a fan mechanism 200 installed in the cabinet 100, and a waste oil collection mechanism 400 installed in the cabinet 100.

[0032] Electric field unit 300 is used to adsorb and purify oil fume particles;

[0033] The fan mechanism 200 includes a dual-inlet centrifugal fan 201, which provides power for the extraction of oil fumes;

[0034] Waste oil collection mechanism 400 includes an oil mesh 401 and an oil receiving tray 402;

[0035] The electric field unit 300, in conjunction with the oil mesh 401, collects the e-liquid into the oil receiving tray 402.

[0036] In use, the fumes pass through the oil mesh 401, where large particles of fumes are intercepted. The fumes that pass through the oil mesh 401 then pass through the electric field unit 300, where the fumes are purified and collected by the electric field. The fumes then flow into the oil mesh 401 and finally into the oil collection tray 402. The waste oil in the oil collection tray 402 can be disposed of periodically.

[0037] Example 2

[0038] Reference Figure 1 and Figure 4This is the second embodiment of the present invention. Unlike the previous embodiment, the dual-inlet centrifugal fan 201 includes a fan body 201a fixedly installed on the inner wall of the cabinet 100. The dual-inlet centrifugal fan 201 has two fan inlets 201d, and the gas entering is purified gas. The output end of the dual-inlet centrifugal fan 201 is fixedly provided with a silencer duct 201b, which effectively reduces equipment noise. The outlet is provided with a fan outlet 201c to discharge the gas.

[0039] The oil filter 401 is fixedly installed inside the cabinet 100, and the oil filter 401 has multiple oil receiving grooves 401a and multiple oil baffles 401b fixedly installed, as shown in the figure. Figure 4 The e-liquid enters the oil mesh 401 through the oil receiving groove 401a, and flows into the oil receiving tray 402 below the oil mesh 401 through the channel formed by the oil baffle 401b.

[0040] The oil receiving tray 402 has a drawer-type structure, which can periodically process the waste oil in the oil receiving tray 402, and is slidably located below the oil mesh 401. The oil receiving tray 402 is provided with an oil fume inlet 402a.

[0041] The cabinet 100 is equipped with a top cover 101 fixed above it, and the top cover 101 is connected to the cabinet 100. A louver 101a is fixed on one side of the top cover 101, and a top cover 102 is fixed on the top cover 101. The top cover 102 is lined with sound-absorbing cotton. The gas discharged from the sound-absorbing duct 201b blows onto the sound-absorbing cotton inside the top cover 102, and then is discharged from the louver 101a through pressure accumulation and detour. The structure inside the top cover 101 adopts the principle of static pressure box, which effectively further reduces equipment noise and discharges gas.

[0042] The cabinet 100 has a fan box door panel 100a and an electrostatic purification box door panel 100b on the front side. Opening the fan box door panel 100a and the electrostatic purification box door panel 100b facilitates equipment inspection and maintenance.

[0043] The electric field unit 300 includes a conductive sheet, an electric field conductive spring, an insulator, etc.

[0044] In use, the oily fumes enter the equipment through the oil fume inlet 402a and then through the oil mesh 401. The specially structured oil mesh 401 can pass through fumes but not liquids. When the fumes pass through the oil mesh 401, large particles of fumes are partially intercepted by the oil mesh 401 through collision, detour, acceleration, and deceleration. The fumes that pass through the oil mesh 401 then enter the electric field unit 300. The electric field is a high and low voltage grid plate electric field. When the fumes pass through the high voltage section, they are charged through the principles of high voltage electrode discharge and ionization. The charged fumes particles are adsorbed on the plates to complete purification and collection. The fumes adsorbed on the plates flow along the plates into the oil mesh 401 and finally into the oil receiving tray 402. The oil receiving tray 402 has a drawer-type structure, and the waste oil in the oil receiving tray 402 can be disposed of periodically.

[0045] The present invention also includes an electrical control box 202, which is used to provide power and control for the device;

[0046] It should be noted that, referring to Figure 1 The electrical control box 202 is installed inside the cabinet 100, greatly reducing the risk of water ingress into the electrical control system and saving space. The electrical control box 202 houses a frequency converter, a timer switch, and a high-voltage power supply. The high-voltage power supply provides high-voltage power to the electric field. The frequency converter controls the soft start and speed of the fan, effectively reducing the impact of motor startup on the power grid and lowering fan noise, while also controlling the exhaust volume. The timer switch controls the on / off time of the equipment, automatically operating and shutting down within a set time period, eliminating the need for manual operation. The high-voltage power supply is connected to the electrode plates in the insulator via a high-voltage power line. The electrode plates are reliably connected to the electric field's conductive spring through spring pressure, providing power to the electric field. All of these are commonly used devices and represent existing mature technologies; their electrical connections and specific circuit structures will not be elaborated upon here.

[0047] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
