Description

Technical Field

[0001] The utility model relates to the technical field of rail transit air purification, in particular to an air purification device for rail transit carriages. Background Art

[0002] Rail transit has become the first choice for people to travel because of its convenience, but the air quality inside the train cars often does not meet the standards, which harms the health of passengers. The main reasons for the air pollution inside the train cars are: (1) the harmful substances such as TVOC are continuously released by the decoration materials, hydraulic pipes, wires and cables inside the train cars; (2) the dense crowds inside the train cars, bacteria, viruses, body odor, breath odor, luggage odor and various food odors are mixed together, aggravating the air pollution; (3) the air pollution outside the train is serious. During the ventilation process, TVOC volatile organic compounds, sulfur dioxide, nitrogen oxides, PM2.5 haze particles, etc. inevitably flow into the train cars. According to the test, the main pollution inside the train cars is TVOC exceeding the standard, among which toluene accounts for 31.4248%, xylene accounts for 10.4103%, styrene accounts for 5.5346%, dimethyl paratoluidine accounts for 0.8520%, and other volatile organic compounds include benzothiazole, acetophenone, undecane, etc. These volatile organic compounds are very harmful to the human body. Existing technologies for indoor air purification at home and abroad are mainly based on filters and activated carbon adsorption, which can only absorb particulate pollutants such as PM2.5 and PM10. They have a short service life, high cost and are prone to secondary pollution. In recent years, electrostatic dust removal technology has been widely used in the field of air purification. This technology uses an electrostatic field to ionize the gas so that dust particles are charged and adsorbed on the electrode, which plays a role in purifying the air. It has high dust removal efficiency and low energy consumption. However, electrostatic dust removal is prone to produce ozone. High concentrations of ozone can cause harm to the human body. Moreover, this technology can only control particulate pollution and cannot control harmful gases such as TVOC. In addition, this technology equipment is complex, difficult to install and maintain, and is not suitable for installation and use in train carriages. Utility Model Content

[0038] Example:

[0039] This embodiment introduces an air purification device for rail transit carriages.

[0040] like Figure 1 、 2 As shown, Figure 1 This is a structural diagram of an air purification device for rail transit carriages of the utility model. Figure 2 Schematic diagram of the exploded view of the air purification device shown.

[0041] An air purification device for a rail transit carriage, comprising: an air inlet, a purification device cabinet 11, a positive and negative ion generating module 6, an air supply fan 7, a top air supply port 8, and a transparent openable back panel 111;

[0042] The air inlets are located on the left and right sides of the purification device cabinet 11;

[0043] The positive and negative ion generating module 6 is located inside the purification device cabinet 11;

[0044] The air supply fan 7 is installed on one side of the purification device cabinet 11;

[0045] The top air outlet 8 is located outside the air supply fan 7, and the top air outlet 8 delivers purified air into the vehicle compartment through the air supply fan 7;

[0046] The transparent openable back panel 111 is located on the other side of the purification device cabinet 11;

[0047] The purification device cabinet 11 is provided with a power module 4, which includes a 220V power interface, a connector, a transformer and an energy storage device to provide power guarantee for the operation of related electrical components.

[0048] Furthermore, the air inlets on the left and right sides are connected, and after the air is delivered by the top air outlet, a negative pressure is formed inside the purification device, and the air inlets on the left and right sides are naturally inlet.

[0049] Furthermore, the air inlet includes a first coarse filter 1, a second coarse filter 2, and a high-voltage electric field dust collection module 3, which are arranged in sequence;

[0050] The first coarse filter 1 is connected to the purification device cabinet 11 by rivets and is a non-detachable part.

[0051] The second coarse filter 2 and the high-voltage electric field dust collection module 3 are respectively installed in a filter element frame 112 , and the filter element frame 112 is installed on the purification device cabinet 11 .

[0052] In this embodiment, the filter element frame 112 includes an inner layer and an outer layer, the second coarse filter 2 is embedded in the inner layer from one side of the filter element frame 112, and the high-voltage electric field dust collection module 3 is located in the outer layer.

[0053] Furthermore, the inner side of the filter element frame 112 is fixedly connected to the purification device cabinet 11 through a long hinge 113, the outer side of the filter element frame 112 is fixed to the purification device cabinet 11 through a ball buckle 116, and the limit baffle 114 is connected to the filter element frame 112 through a hinge 115.

[0054] Furthermore, the first coarse filter 1 is a screen and cannot be removed; the second coarse filter 2 is a G4 primary filter, which can be removed and cleaned or replaced; the high-voltage electric field dust collection module 3 has a built-in NCCO oxygen decomposition reaction module, and the high-voltage electric field dust collection module 3 can be removed and cleaned or replaced.

[0055] In this embodiment, unpurified air enters the first coarse filter 1, which is a 4-mesh screen that can filter out large particle pollutants of 5mm and above; then the air enters the second coarse filter 2, which is a set of G4 primary filter screens that can effectively filter suspended matter with a particle size of ≥5 microns. Next, the air enters the high-voltage electric field dust collection module 3, which integrates electric field dust removal technology and nano-oxygen polymerization and decomposition technology, and can effectively remove dust (including PM2.5, PM10, etc.). The high-voltage electric field can inhibit bacterial reproduction and kill bacteria adhering to dust particles. At the same time, the NCCO oxygen polymerization reaction module in the high-voltage electric field dust collection module 3 can adsorb volatile organic compounds such as aldehydes, benzenes and odor substances in the air, and catalytically decompose them into water and carbon dioxide. No harmful substances are produced in this process, and water and carbon dioxide can flow away with the air without causing secondary pollution.

[0056] Furthermore, the air processed by the first coarse filtration 1, the second coarse filtration 2, and the high-voltage electric field dust collection module 3 enters the interior of the air purification device. The internal positive and negative ion generating module is a dielectric barrier discharge positive and negative oxygen ion air purification device. The positive and negative ion generating module 6 generates and releases positive and negative oxygen ions. Through the physical impact of positive and negative ions and the chemical reaction between positive and negative ions, it can simultaneously meet multiple air purification needs such as decomposing harmful volatile gases in the air, sterilizing, removing odors, and reducing dust, thereby greatly improving the air cleanliness.

[0057] Furthermore, the transparent, removable back panel 111 is secured to the purification device cabinet 11 using a cam sleeve quick-release fastener. Made of transparent acrylic, this allows for visual inspection of the operating status of the cabinet's main components and electrical elements. When maintenance or replacement of the power module 4, monitoring module 5, or positive and negative ion generator module 6 is required, the cam sleeve quick-release fastener is simply opened to remove the transparent, removable back panel 111 for immediate maintenance.

[0058] Furthermore, a handle 117 is provided on the limit baffle 114. When the high-voltage electric field dust collecting module 3 needs to be maintained or replaced, the handle 117 is only needed to be held to pull the limit baffle 114 outward, and the hinge 115 is rotated outward to drive the limit baffle 114 to open outward. Figure 1 As shown in the open state at A, the high-voltage electric field dust collection module 3 can be disassembled at this time.

[0059] When the second coarse filter 2 needs to be maintained or replaced, the handle 117 is held and the filter element frame 112 is pulled to the right (left). At this time, the bead buckle 116 and the buckle will be separated, and the long hinge 113 can be rotated. Figure 1 As shown in the rotating state at B, the second coarse filter 2 can be taken out from the inner layer of the filter element frame.

[0060] like Figure 3As shown, Figure 3 Figure 5 is a schematic diagram of the monitoring module for an air purification device. The monitoring module 5 comprises a data collection board 51, a data acquisition sensor 511, and a control board 52. Before the air inside the purification device cabinet is blown out by the blower 7, the data acquisition sensor 511 collects the TVOC, SO2, CH2O, PM2.5, and CO2 contents in the air. The data collection board 51 then transmits the information to the control board 52 via the RS485 serial port. The control board 52 then uses pre-set logical XOR (XOR) operation rules to analyze the data transmitted by the data collection board 51.

[0061] In this embodiment, in order to achieve rapid maintenance and replacement of major components, such as the high-voltage electric field dust collection module 3, the positive and negative ion generation module 6, and the air supply fan 7 and the power module 4 and the monitoring module 5, quick plug-in connectors are used. When replacing the relevant major components, it is only necessary to disconnect the connector to replace them, which is convenient and quick.

[0062] like Figure 4 、 5 As shown, Figure 4 This is a schematic diagram of the top air outlet of the air purification device. Figure 5 The top air outlet 8 is provided on a mounting plate, on which a touch screen 9 and an automatic button 10 are provided.

[0063] Furthermore, when the automatic button 10 is pressed to turn on the air purification device, the control board 52 enters the automatic control system, the data acquisition sensor 511 continuously collects data, and the control board 52 analyzes the data and presets the program to control the working status of the high-voltage electric field dust collection module 3, the positive and negative ion generation module 6 and the air supply fan 7.

[0064] Furthermore, the touch screen 9 includes three interface modes: a mode interface 91 , a status interface 92 and an air quality interface 93 .

[0065] The mode interface 91 includes automatic control, fast purification and silent modes. When any manual control is activated, the purifier exits automatic control;

[0066] The status interface 92 is used to display the working status of each module in real time, including the speed of the air supply fan 7, the working status of the high-voltage electric field dust collection module 3 and the positive and negative ion generating module 6;

[0067] The air quality interface 93 displays the air quality indicators in the vehicle cabin in real time, including formaldehyde content, PM2.5 value, TVOC value, carbon dioxide content and air humidity ratio.

[0068] like Figure 6 As shown, Figure 6Schematic diagram of the air supply fan of the air purification device. The air supply fan 7 includes a blower bracket 71 and a blower tray 72. The blower bracket 71 is installed on the blower tray 72.

[0069] When maintenance of the air blower 7 is required, the top air outlet 8 is lifted upward, the blower quick-plug connector is disconnected, the fixing bolts of the blower tray 72 are removed, and the air blower 7 together with the blower bracket 71 and the blower tray 72 are removed from the top air outlet 8. After removal, the blower bracket 71 is removed separately. At the same time, in order to reduce the noise and vibration of the air blower 7 during operation, a special blower guide ring 721 is provided. When air is sucked in from one side, compressed by the rotating blades and discharged to the other side, the fan guide cover 721 can guide the gas entering the blower to the impeller and make it evenly distributed, avoiding problems such as local resistance and gas backflow.

[0070] The air purification device designed by the present invention has a simple structure and is easy to install and maintain. The air purification device can greatly improve the air quality in the vehicle compartment and create a fresh and comfortable riding environment.

[0071] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
