Abstract

PURPOSE:To eliminate the temporary lowering of dust collection efficiency and the damage of a filter material, by connecting a high voltage power source apparatuses to each upstream side and each downstream side separators put in meandering filter materials through a conductive material having resistance preventing the movement of charge. CONSTITUTION:When a dust containing gas is sent into from the inlet of a vessel frame in such a condition that DC high voltage is applied to an ionizing wire 30 and a separator 15, dust particles 47 are charged by corona discharge and, in a process wherein the gas containing the charged particles 47 is passed through a dust collecting part, most of the charged particles 47 are adhered to the surface of each separator 15 in the upstream side and removed from said gas. Subsequently, the gas 48 containing the residual charged particles 47 is passed through a filter material 14 in the shortest distance and the charged particles 47 are deposited on the surface of the filter material 14 in a porous form. In the next stage, the charged particles 47 generated into the filter material 14 are moved along electric lines of force gathered to the fiber of the filter material by an electric field applied between separtors 15, 16 and, therefore, the area collected by the fiber is greatly increased.

However, as shown in Figure 147, separator = 19, (16
If power is supplied individually through the resistors R1 to R% of the conductive rubber sheets, even if a discharge occurs at one location on a certain separator, the amount of discharge will be limited by the resistors R1 to Rf&. Since the charges accumulated between the other separators do not move to the discharge point, the discharge energy is reduced to approximately one-third when the resistors R1 to Rs are not used.
In other words, it becomes.

According to experiments, when the voltage IKV, the filter material leak resistance is 200 MΩ, the filter material leak current is 5 μA per separator stage, and the capacitance 3 between separators is 3 x 10 F, the effect of limiting the amount of discharge is determined by the value of the resistance R%. Although it depends on the capacitance between the separators, it becomes apparent when it becomes more than IOKΩ,
The higher the resistance value, the smaller the charge transfer between the separators. However, if the value of the resistor Ra is made too large, a voltage drop will occur across the resistor R% due to leakage, and the voltage applied between the separator and the resistor will actually drop.

Therefore, in the case of the above example, the range of resistance Rs is 10Ω to I

Next, to explain the operation of the ultra-high-performance electric filter with the above configuration, in a state where a high DC voltage is applied to the ionization line and the separator 09, the main frame (9
), the dust particles are charged by corona discharge while passing through the charge IE part formed by the polar vinegar and the ionized wire, and the charged particles ? Each separator whose content is on the smooth side (
151, and each effect is more pronounced for charged particles with larger particle sizes. Next, the airflow of gas containing the remaining charged particles (2) passes through the filtering medium (141) in the shortest distance since the pressure loss of the filtering medium I is very large.Therefore, the airflow passes through the separator as shown in Figure 1O. 〇It is almost parallel to and opposite to the electric line of force that goes from Fg to α.At the same time, the electric force
! The speed of fH is filter medium α4? When passing through, the speed is extremely slow compared to the speed (surface wind speed) upstream of the dust collection section. In this way, when the direction of the electric field and the direction of the air flow are reversed.

The moving speed of the particle 4°9, i.e. the electric force lines -
Since the moving speed in the direction of Q41 becomes greater than the speed of the airflow passing through the filter medium 141, the charged particles cannot enter the inside of the filter medium Q41.On the other hand, since the airflow speed of the filter medium I is fast, the charged particles - is deposited in a porous manner on the surface of the spindle filter 1 (14).Next, the charged particles that are not deposited in a porous manner and enter the filter material (I41) are separated by the electric field applied between the sepabeater (151 and 061). Filter media 04
As the particles move along the lines of force that gather around the fibers, the area captured by the fibers increases dramatically.

Due to the above dust collection mechanism, the dust collection efficiency is significantly increased and clean gas is forced out from the outlet of the main frame (9). In addition, since charged particles with large particle diameters are more effectively collected by each separator (Is), there is less clogging inside the filter medium, and the life of the filter can be significantly extended.

Even if the separators on the downstream side (separators 〇〇 on the I or upper sliding side are inserted somewhat irregularly, the fine pieces of AM (c) will contact the individual separators, so there will be no damage to the docking area. It has the advantage that it does not occur.6

The present invention consists of all of the above-mentioned components, and the Takasho II is connected to each upstream separator and each downstream separator sandwiched in a meandering filter medium through a conductive material having an electrical resistance that prevents the movement of charges in each separator. source device can be connected,
When a discharge occurs at one location of a separator, the amount of discharge is increased by the electrical resistance, and it is possible to prevent all of the charges in the separator from moving to the discharge location.
Discharge energy can be kept small. Therefore, the separator voltage does not temporarily decrease due to discharge, and therefore the dust collection efficiency does not decrease temporarily. It also has the advantage that there is no risk of damage to the filter medium such as holes in the filter medium.
