Abstract

PURPOSE:To strongly polorize both a charged filter and dust attracted on the charged filter and to remove it by providing a grounded conductive net to the upstream side while pinching the charged filter and providing the conductive net impressed with high voltage to the downstream side. CONSTITUTION:When an air cleaner is operated and a fan 4 is actuated, the air incorporating dust in a room is introduced through a suction port 1 and corona discharge is caused toward the earth electrodes 7 of a negative side from the high-voltage discharge wires 6 in a charge part 5 and the introduced dust is charged to positive. Then the dust charged to positive is partially attracted on a grounded conductive net 12 by Coulomb's force and removed but the large parts of dust are allowed to flow to a discharge port 2 side together with the air by the fan 4 and introduced into a charged filter 8. Herein fiber 9 forming the charged filter 8 has been polarized to positive and negative and the dust charged to positive is attracted on fiber 9 by Coulomb's force and removed from the air.

The pressure loss is approximately 2 Aq at a wind speed of 0.3 m/s.

A conductive net grounded at e is placed on the downstream side, and a conductive net applied to a high voltage at e is placed on the downstream side, so a strong electric field is applied to the charged filter, and the attached dust particles are more strongly polarized, making them more powerful. - Dust is collected by Ron force. Therefore, even if the charged filter is made coarser, the dust collection ability is maintained.

When used by reducing the distance between the ground wire and the grounded conductive net, a stronger electric field can be generated, which generates a stronger force and maintains the conventional dust collection efficiency. The dust will then be collected.

Note that the same parts as those in the conventional example are given the same numbers and their explanations are omitted. In FIG. 1, a conductive network 11 is provided downstream of a charged filter 8 made up of a large number of polarized fibers 9 shown in FIG.

charged. (2) The charged dust adheres to the conductive net 12, which is partially grounded, and is removed by the Coulomb force, but most of the dust flows to the discharge port 2 side together with air by the blower 4 and flows into the charging buiflet 8. The fibers 9 and e forming the charged filter 8 are polarized, and the e-charged dust adheres to the fibers 9 by Coulomb force and is removed from the air. A conductive net 12 that is grounded and applied to e is provided on the upstream side of the charged filter 8, and a conductive net 12 that is applied to a high voltage is provided on the downstream side. A strong electric field is generated, and the fibers 9 of the charged filter 8 and the dust attached to the fibers 9 are strongly polarized into ■ and e, and the charged dust flows in. ■ The charged dust is strong - the charged filter is moved by the Ron force. 8 and is removed from the air.

Since the conductive net 11 applied to the e-side high voltage is provided downstream of the charged filter 8, the incoming charged dust is repelled because it has the same polarity, and the speed at which it passes through the charged filter 8 is slow. Therefore, the charged filter 8
This makes it easier for dust particles to be captured by dust particles, making it possible to process them with high dust collection efficiency at larger air volumes (higher flow velocities).

When the wire covered with is assembled as shown in Fig. 1, a conductive net 12 grounded at e and covered with an insulating material 13 are formed.
Even if dust is collected and accumulated between the conductive net 11 and the conductive net 11 to which a high voltage is applied, spark discharge is unlikely to occur, so the distance between both conductive nets 11 and 12 can be shortened If the interval is shortened, a stronger electric field is applied to the charged filter 8, so even if the charged filter 8 is made coarser and has a lower pressure drop, the dust collection performance can be maintained. Therefore, it can be made compact and can handle a large amount of air.

The configuration is as follows. Therefore, even if the conductive nets 12 and 14, which are applied to θ and grounded provided on the air inflow side and the air outflow side of the charged filter 8, are brought closer together, spark discharge due to the collection and accumulation of dust will not occur, and the It is possible to generate a strong electric field. As a result, dust collection performance is maintained even if the charged filter is made coarser and has a lower pressure drop, making it possible to make it more compact and handle large air volumes.

。Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, there is a conductive net that is grounded on the upstream side across the charged filter, and a conductive net that is applied with high voltage on the downstream side. Since a strong electric field is generated, the charged filter and the dust attached to the charged filter are strongly polarized.
The inflowing charged dust becomes strong and is collected by the charged filter due to the force of the charge and removed from the air. Therefore, even if the charged filter is made coarser and has a lower pressure drop, the dust collection ability is maintained, so it can be made more compact with a larger air volume.

りコンパクト化が図れる。In addition, in the third method, there is a high voltage line (■) inside the charged filter,
In addition to providing multiple parallel earth wires alternately,
Since a grounded conductive net is provided close to the charged filter on the upstream and downstream sides, a strong electric field is generated inside the charged filter around the high-voltage wire (■), so the charged filter and the charged filter The dust adhering to the tube is strongly polarized, and the incoming charged dust particles are collected by the strong Ron force and removed from the air. Therefore, even if the charged filter is rougher and has a lower pressure drop than the second means, the dust collecting power is maintained, and the air volume can be larger than that of the second means, and the device can be made more compact.

できよシコンパクト化が図れる。In addition, in the third method, the high voltage wire (■) is coated with insulation, so that even if dust is collected and accumulated, spark discharge is suppressed. The distance between the charged conductive mesh and the charged filter can be made much smaller, a higher electric field is generated within the charged filter, and the dust collection performance is improved even if the charged filter is coarser and has lower pressure drop than the third method. The airflow rate can be maintained larger than that of the third means, and the airflow can be made more compact.

きよシコンパクト化することができる。In addition, in the fifth method, the charged filter, the grounded conductive net, and the conductive net applied to the high voltage are formed in a pleated shape, resulting in lower pressure loss and higher dust collection power (as compared to the first method). It is possible to achieve a larger air volume than the first means, and it is possible to make it more compact.
