Description

Technical Field

[0001] The invention relates to an electrostatic purification device. Background Art

[0002] At present, in order to prevent oil smoke from polluting the environment, people usually install special oil fume purification devices on the flue to eliminate oil fume pollutants. Existing oil fume purification devices have various structures, including filter membrane type, water curtain type and centrifugal type. Among them, although the filter membrane type purification device can effectively remove oil fume, it is easy to clog and must be replaced frequently, which is troublesome to use. The water curtain type purification device uses water to remove oil fume, which is not only easy to cause secondary pollution, but also wastes a lot of water and has a high cost of use. The centrifugal purification device not only produces a lot of noise when working, but also has a relatively low removal rate for oil fume.

[0003] In order to overcome the defects of the above-mentioned existing oil fume purification devices, people have proposed an electrostatic purification device, such as the "Oil Fume Electrostatic Purification Device" disclosed in Patent No. ZL 02257040.3 (Authorization Announcement No. CN 2586536 Y), which includes a power supply, a box, an electrode plate, and an oil collecting basin. The box is a closed structure, and the box is provided with an air inlet and an air outlet connected to the smoke exhaust pipe; the electrode plate includes a positive plate and a negative plate, and the positive and negative plates are vertically arranged in the box and alternately arranged parallel to each other at an appropriate distance; the oil collecting basin is arranged below the electrode plate; the power supply provides DC high voltage electricity to the electrode plate. When the device is working, an electrostatic field is formed on the oil and gas channel, and under the action of the electrostatic field, the tiny oil droplets entering the electrostatic field are adsorbed to the electrode surface. Although the electrostatic purification device has the advantages of low energy consumption, low noise, and no secondary pollution, it adopts a simple staggered structure of positive and negative plates. The positive and negative plates are not staggered with each other. The positive and negative plates are installed on the same support frame. When oil accumulates on the support frame, the surface is prone to creep electricity, and the current is concentrated on the surface discharge, resulting in a reduction in the number of moving charged particles between the plates, making it easy for the positive and negative plates to conduct, thereby rendering the electrostatic purification device ineffective. For example, there is an electrostatic purification device in which insulating brackets are installed on two opposite sides of the outer support frame, and springs are installed on the inner side of the insulating bracket. The two ends of the electrode wire are respectively installed on the springs on the corresponding sides. Since multiple electrode wires need to be installed, it is easy to touch the installed electrode wire when winding the wire, which brings certain inconveniences to the installation of the electrode wire. In summary, further improvements need to be made to the existing electrostatic purification device. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an electrostatic purification device with convenient electrode wire installation in view of the above-mentioned existing technical status.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: the electrostatic purification device includes an outer support frame, a positive plate, a negative plate and an electrode wire, the positive plate and the negative plate are distributed at intervals inside the outer support frame, and positive plate connecting plates are provided on the left and right sides of the arrangement direction of the positive plate and the negative plate. The positive plate is connected and fixed on the positive plate connecting plate, and the electrode wire is mutually conductive with the positive plate, characterized in that: the electrode wire is wound back and forth on the positive plate connecting plates on both sides and passes through the gaps between adjacent negative plates in sequence.

[0006] Preferably, the positive plate connecting plates on both sides are provided with wire winding holes spaced apart along the arrangement direction of the positive plates and the negative plates, and the electrode wires pass through the wire winding holes on both sides one by one.

[0007] Preferably, the electrode wire passing through the gap between adjacent negative electrode plates is located directly below the corresponding positive electrode plate.

[0008] The electrode wire can be fixed on the positive plate connecting plate through a variety of structural connections. The first spring and the second spring are respectively installed at both ends of the electrode wire. Spring connecting holes are opened on both sides of the positive plate connecting plate. The first spring and the second spring are respectively connected to the corresponding spring connecting holes.

[0009] As a preferred solution, the first spring and the second spring are arranged in the gap between adjacent negative plates.

[0010] As another preferred solution, a spring installation hole is opened on the positive plate connecting plate, and the first spring and the second spring are arranged in the spring installation hole. In this way, the spring is not arranged in the charging area, which can increase the effective discharge stroke of the electrode wire, thereby facilitating the improvement of the electrostatic purification effect.

[0011] In order to improve the electrostatic purification effect, the positive plate connecting plate on the same side has two upper and lower pieces, and the upper positive plate connecting plate and the lower positive plate connecting plate each correspond to an independent electrode wire.

[0012] Further preferably, the lower positive plate connecting plate is provided with two upper and lower rows of the wire winding holes, and different rows of the wire winding holes correspond to independent electrode wires.

[0013] In order to make the installation structure of the positive plate and the negative plate more firm, a negative plate connecting plate is provided above the positive plate connecting plate, and the two sides of the negative plate are respectively connected and fixed to the corresponding negative plate connecting plates, and the outer support frame includes a first support plate and a second support plate arranged oppositely on the front and rear sides of the arrangement direction of the positive plate and the negative plate, and the positive plate connecting plate and the negative plate connecting plate are both connected and fixed between the first support plate and the second support plate.

[0014] As a preferred embodiment of any of the above schemes, the electrostatic purification device has an air inlet and an air outlet, the side of the outer support frame close to the air inlet is a charging area, the side of the outer support frame close to the air outlet is a dust collecting area, and the electrode wire is arranged in the charging area.

[0015] Compared with the prior art, the advantages of the present invention are that the electrode wire of the electrostatic purification device is wound back and forth on the positive plate connecting plates on both sides, and passes through the gaps between adjacent negative plates in turn. When winding the wire, only one end of the electrode wire needs to be fixed on the positive plate connecting plate, and the other end needs to be wound back and forth between the positive plate connecting plates on both sides. Only one electrode wire needs to be wound on the same layer, which is very convenient and can ensure that the electrode wire has sufficient effective discharge stroke.

[0023] The present invention is further described in detail below with reference to the accompanying drawings.

The side of the outer support frame near the air inlet is the charging area, and the side of the outer support frame near the air outlet is the dust collection area. Figure 1The direction indicated by the middle arrow A is the air inlet direction. The first support plate 71 and the second support plate 72 constitute an outer support frame, and the positive plate 1 and the negative plate 2 are spaced apart between the first support plate 71 and the second support plate 72. The positive plate connecting plate 4 and the negative plate connecting plate 5 are provided on both sides of the arrangement direction of the positive plate 1 and the negative plate 2. The arrangement direction of the positive plate 1 and the negative plate 2 is the length direction of the positive plate connecting plate 4 and the negative plate connecting plate 5. The positive plate 1 is connected and fixed to the positive plate connecting plate 4, and the negative plate 2 is connected and fixed to the negative plate connecting plate 5. The negative plate connecting plate 5 is located above the positive plate connecting plate 4, and the positive plate connecting plate 4 and the negative plate connecting plate 5 are both connected and fixed between the first support plate 71 and the second support plate 72. In addition, in order to further fix the positive plate 1 and the negative plate 2, the top of the positive plate 1 is connected and fixed by the upper fixing bar 81, and the bottom of the negative plate 2 is connected and fixed by the lower fixing bar 82.

[0025] In this embodiment, the positive plate connecting plate 4 on the same side has two upper and lower pieces, such as Figure 3 The figure shows one of the positive plate connecting plates 4, on which the positive plate connecting plate 4 is provided with wire winding holes 41 arranged at intervals along its length. Figure 4 Another positive plate connecting plate 4 is shown, which has two rows of wire winding holes 41, and each row of wire winding holes 41 is spaced apart along the length direction of the positive plate connecting plate 4. Spring connecting holes 42 are provided on both sides of the positive plate connecting plate 4.

[0026] The electrostatic purification device of this embodiment is provided with a total of three electrode wires 3, and the electrode wires 3 are arranged in the charging area. Among them, one electrode wire 3 is wound on the positive plate connecting plate 4 above the wire, and the other two electrode wires 3 are wound on the positive plate connecting plate 4 below. Figure 2 shown.

[0027] The following description will be made by taking the installation structure of the electrode wire 3 installed on the upper positive plate connecting plate 4 as an example.

[0028] The first spring 61 and the second spring 62 are respectively installed at both ends of the electrode wire 3. When winding the wire, first, the first spring 61 is installed at one end of the electrode wire 3, and the first spring 61 is hooked on the spring connection hole 42; then, the electrode wire 3 is passed around the wire winding holes 41 on the two opposite positive plate connection plates 4 one by one; finally, the second spring 62 is installed at the other end of the electrode wire 3, and the second spring 62 is hooked on the corresponding spring connection hole 42.

In addition, in this embodiment, a spring mounting hole 43 is opened on the positive plate connecting plate 4. When winding the wire, the first spring 61 and the second spring 62 are arranged in the spring mounting hole 43. In this way, the spring is not arranged in the charging area, which can increase the effective discharge stroke of the electrode wire 3, thereby facilitating the improvement of the electrostatic purification effect.
