DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0028] like Figure 1-Figure 3 As shown, the air filtration station provided in this example includes a louver 11, an electrostatic filter 9 and a filter cloth 2, wherein the louver 11 is arranged at the air inlet of the air filtration station, the air inlet end of the electrostatic filter 9 is connected to the air outlet of the louver 11, the air inlet end of the filter cloth 2 is connected to the air outlet end of the electrostatic filter 9, the air outlet end of the filter cloth 2 is connected to the air inlet of the generator set, and a gas containing cavity is formed between the filter cloth 2 and the electrostatic filter 9.

[0029] With such a structural arrangement, the air entering the air filtration station can be filtered step by step through the shutters 11, the electrostatic filter 9 and the filter cloth 2, providing clean air for the normal operation of the generator set and the cooling of the fuselage.

[0030] In the specific setting, the shutter 11 is arranged at the air inlet of the air filter station through the shutter fixing member 12, so that dust, gravel, rainwater and the like in the air entering the shutter 11 can be blocked out.

[0031] like Figure 7 As shown, as an example, the shutter 11 here includes a plurality of shutter blades arranged in sequence and connected, which are composed of a guide blade 11a, a first shielding blade 11b and a second shielding blade 11c.

[0032] The guide blade 11a is preferably composed of an S-shaped blade, and the first shielding blade 11b and the second shielding blade 11c are respectively arranged on both sides of the guide blade 11a and extend in opposite directions.

[0033] Specifically, the first shielding blade 11b is arranged on one side of the guide blade 11a and extends along the air inflow direction of the generator set. Here, the first shielding blade 11b is preferably composed of an arc-shaped blade, and the concave surface of the arc of the first shielding blade 11b is preferably arranged relative to the air inlet direction.

[0034] With such a structure, when the air flows in from under the first shielding blade 11 b , dust, sand, large-particle salt mist, etc. in the air can be shielded from outside.

[0035] The second shielding blade 11c is arranged on the other side of the guide blade 11a and extends in the opposite direction of the air inflow. Such a structure can block dust, sand, large-particle salt mist, etc. in the air when the air flows in from the first shielding blade 11b.

[0036] The shutter 11 is arranged based on the above structure. In specific applications, a unique flow channel structure is formed between adjacent shutter blades. The air flow can enter the air inlet of the generator set along the guide blade 11a, while the dust, sand, large-particle salt mist, etc. in the air cannot enter the air inlet of the generator set due to the blocking of the first shielding blade 11b and the second shielding blade 11c, thereby filtering the incoming air.

[0037] The electrostatic filter 9 is arranged at the air outlet of the louver 11 to absorb fibers, catkins, cotton wool, etc. in the air and perform secondary filtering on the air filtered by the louver 11.

[0038] The electrostatic filter 9 is composed of interlaced metal wires and uses the principle of high-voltage electrostatic adsorption to remove particulate pollutants in the air. When the air passes through the ionizing wire of the generating electrode, the air molecules are ionized into positive ions and electrons. The electrons combine with the smoke particles to make the dust particles carry an electric charge.

[0039] There is an attraction between opposite charges. When air passes through the charged anode substrate, the negatively charged dust particles will move toward the anode plate and attach to it under the action of the electric field force.

[0040] When air passes through the charged negative electrode substrate, the positively charged dust particles will move toward the negative plate and attach to it under the action of the electric field force. In this way, the dust particles are captured on the plate and clean air flows away.

[0041] In the specific configuration, one end of the electrostatic filter 9 is suspended on the shutter fixing member 12 and can swing around it. Such a structural configuration can ensure the secondary filtering effect of the electrostatic filter 9 on the one hand, and prevent obstruction to the air flow on the other hand.

[0042] The filter cloth 2 is used to perform a third filtration on the air that has been filtered twice by the electrostatic filter structure 2. In a specific configuration, its air inlet end is connected to the air outlet end of the electrostatic filter 9, and the air outlet end is connected to the air inlet window 13 of the generator set, forming a gas containing chamber between the filter cloth 2 and the electrostatic filter 9.

[0043] The gas containing cavity can ensure that the outside air can enter the air filtering station without hindrance, and provide a space for the incoming air.

[0044] Preferably, the gas containing chamber is preferably configured as an annular structure. Such a structure allows the air to contact the filter cloth 2 with as large an area and space as possible after passing through the outlet of the electrostatic filter 9, and to be filtered three times.

[0045] The filter cloth 2 is specifically arranged by arranging a filter cloth support 10 on the tray 3 of the air filter station and placing the filter cloth 2 in the groove of the filter cloth support 10 .

[0046] Preferably, the filter cloth is a filter medium woven from natural fibers or synthetic fibers, and can be used for dust control and purification collection.

[0047] Furthermore, in order to improve the quality of air filtration, the present embodiment is also provided with a vibration motor 1 matched with the filter cloth 2 for vibrating the dust on the filter cloth 2 off.

[0048] During the specific setting, the vibration motor 1 is placed on the filter cloth bracket 10, and its number can be set according to actual needs. The vibration of the vibration motor 1 drives the vibration of the filter cloth bracket 10, and then drives the filter cloth 2 located in the groove of the filter cloth bracket 10 to vibrate, thereby vibrating the dust on the filter cloth 2 off.

[0049] Furthermore, in order to improve the stability and reliability of the air filtering station, an elastic component is provided between the filter cloth support 10 and the tray 3 .

[0050] In a specific configuration, the elastic component is preferably composed of a floating spring 8 .

[0051] At the same time, in order to collect dust falling off the filter cloth 2, the air filter station in this example is also provided with a dust collecting tank.

[0052] Preferably, the dust collecting trough is formed by the tray 3 and the lower beam 6 of the air filter station, and when rain or cleaning fluid flows through the dust collecting trough, the dust can be washed away.

[0053] In order to further improve the filtering effect of the filter cloth 2 and remove the dust accumulated on the filter cloth 2 in time, the filter cloth 2 in this embodiment is also provided with a matching cleaning device.

[0054] As an example, the cleaning device here is composed of a plurality of cleaning nozzles 7 and a nozzle fixing bracket 14, wherein the nozzle fixing bracket 14 is arranged on the filter cloth bracket 10 along the extension direction of the filter cloth 2, and the plurality of cleaning nozzles 7 are evenly distributed on the nozzle fixing bracket 1.

[0055] In specific application, by starting the filter cloth cleaning action, the cleaning nozzle 7 sprays the cleaning liquid on the surface of the filter cloth 2, so as to remove the dust layer and the salt fog crust layer that may exist on the filter cloth 2.

[0056] In addition, the air filtration station is also equipped with a fan 4 for realizing active air intake to increase the air intake volume.

[0057] In the specific setting, the fan 4 is placed in the air inlet window 13 at the top. With such a structural setting, clean air filtered by the shutter 11, the electrostatic filter 9 and the filter cloth 2 in sequence can enter the silent box for use by the generator set.

[0058] Based on the above-mentioned air filtration station structure setting, this example also provides a filtration method of the air filtration station.

[0059] like Figure 4-Figure 6 As shown, the air filter station in this example can perform three-stage filtration on the air entering the generator set. When the engine is started, the fan 4 is started at the same time, forming a negative pressure on the air entering the air filter station, and the air enters along the direction of the arrow in the figure. When the air enters the shutter 11, the shutter 11 blocks the sand, gravel, rain and the like in the air from the outside; when the air passes through the electrostatic filter 9, the electrostatic filter 9 adsorbs the fibers, catkins and cotton wool in the air on the electrostatic filter 9; when the air passes through the filter cloth 2, the filter cloth 2 filters out the dust in the air, and finally the filtered air passes through the air inlet window 13 and enters the generator set A.

[0060] The air filtration station provided in this example can provide clean air for the normal operation of the generator set and the cooling of the fuselage, greatly improving the service life of the engine. At the same time, its self-maintenance function prolongs the service life of related consumables, reduces the number of manual maintenance, and greatly reduces maintenance costs. It can be widely used in the generator industry and the power industry, providing a new intake purification solution for the power and diesel power generation industries.
