Description

Sähkösuodatönien structure of electrostatic precipitators was invented in the late 1800s and used a lot of teollisuuspölyjen filtering and living spaces of air purification. This invention relates mm. the structure of the living spaces of the air cleaner. Although the electric filter is filtering ability, and because of its easily overwhelming air filter, they are still very much in use in private households, where the majority of filters are mechanical filters, Lahan the main reason for the price, which is more expensive electrostatic precipitators. This invention simplifies and cheapens the structure of the electrostatic precipitator and makes it so competitive. In the currently used filters is more than 300 parts. Structure of the invention can survive significantly fewer parts.

Regular electric filter normally has a positive electric charge of several kV having the corona wires, which ionize the particles in the air stream. Thereafter, the flow direction will collection plate pairs, between which the air flow is passed. The second plate is normally O kilovolts potential and the second potential +. In this case, the charged particles drift + 0, and the plates and stick niihin.Voidaan can also use the opposing potentials. In general, filters for domestic use is 5-9 corona wires and 50-100 the collection plate.

The following explains the structure of the device according to the invention.

Figure 1 shows the device in an axonometric view diagonally from the front. Figure 2 shows the device directly to the front. Figure 3 shows the device of the ionization chamber partition plate 5 side. Figure 4 shows the collector plates 4 sides. Figure 5 shows the corona wire 10 supporting rods 8 page. Figure 6 shows the corona wire lOtukisauvaa 8 off. Figure 7 shows a honeycomb of square cross-section of the locking rod freely sliding position. Figure 8 shows the stack of square cross-section of the locking rod in a locked position. Figure 9 shows a honeycomb round lock rod cross-section of freely sliding position. Figure 10 shows a honeycomb circular cross-section of the locking rod in a locked position.

Device support structure according to Figure 1 consists of a top plate 1, bottom plate 3, side plates 2, the ionization chamber division plates 5, 4 of collection plates and the plates 2,4 and 5 in the locking position the locking rods 12 or 14.15. The structure further includes a substantially upper and lower corona wire supporting rods 8 and the corona wires 10 between them, this device consisting of one of the rods 8 between the metal wire inserted into it. The device according to the invention, top plate 1, pohjaievy 3 and two side plates normally attached to each other with screws, rivets or glue. A device according to one picture is 7 ionization chamber, which is separated by division plates 5 extend in front collector plate in the middle of the formation of ionization chambers corona wires 10. The top slab 1 and the bottom plate 3 on the inside of the insulation layer, the surface of the cord grooves 16, leading to electricity collecting plates 4 is essential to the invention the plates 2 , 4 and 5 lock in place relative to each other on smooth insulating material 12 or the locking rods 14,15. Support rods 12 is based on the fact that the circular cross-section of a different, e.g. square or oval cross-section having a rod inserted into the through 11 in the plates plates 2,4 and 5 holes, after which the rod 12 is rotated by a suitable tool to form a profile dependent on the required amount, a square rod of 45 ° so that it Support plates engages the locking rods to the end plates may also be different, which affects the order of assembly of the device. Alternatively lukitussauvoina presented by Figures 9 and 10 the solution can be used. The stick of a tube 14 which is inserted into the through holes in the plates 6, after which the hose is locked in the plates by pushing the appropriate size bar 14 through a hose 15 of the hose 14 to expand, locking the panels in place. Insulation from the substance eg. Plastic corona wire supporting rods 8 are also an integral part of the structure of the device. The uniform corona wire 10, which is stretched between the support rods 8 through the holes or grooves 9 does not constitute any extra, too much corona forming spikes or roughness that can produce too much ozone, which is one of the possible disadvantages of the electrostatic precipitator. Another alternative is to attach the topping corona wire 1 and the base plate 3 of insulating plates or hooks 1 and 3 grooves. In addition, this structure is easy to assemble. According to the plan of the corona wire 10 is 8 kV positive voltage and a second plate assembly 4 is positive 4 kV, the voltage of 0 V and the other voltage, but the voltages can be varied on the basis of the findings of the tests. Voltages are conducted through the plates 4 and 5, the top and on the bottom of nodules, which rest on the top and bottom surfaces of the inner plates 1 and 3 of the insulated wire bottoms of the grooves 16 on the conductors. Wiring grooves 16 may be a little more flexible in order to ensure contact. Wiring grooves are in each, as well as the top slab 1 and the base plate 3 with two. The second leads 4 kV and another zero voltage. The collection plates are alternately turning them be derived in different voltages. The boards 4 and 5 in the holes 6 and 7 are of different sizes so that only disks having the same voltage Having closed my lukitussauvoihinsa 12.14, although the locking rods, or at least the surface layers of insulation material. This is because the use of the plates 4 and 5 and 8 of the surface of the locking rods accumulate dust, which leads to a little electricity and can cause additional outbreaks.
