More specifically, the present invention relates to a method of removing adhering dust by widening the spacing between mesh filters constituting a multilayer filter.

取付けられる。BACKGROUND ART Recently, multilayer filters that collect dust based on the principle of collisional inertia dust collection have been used to collect dust from dust-containing fluids such as dust-containing gases. As shown in Fig. 4, this multilayer filter has a multilayer structure in which a plurality of mesh filters 1-1 are laminated, each having a large number of honeycomb-shaped holes 1-2 formed by pressing a thin metal plate. It is installed in a duct through which dust-containing fluid flows while being housed in a case 12.

間隔を広げていくとガス流の変化が弱まり、集塵
効果が急激に低下する。このため、多層フイルタ
ーのフイルター間隔は通常1.0〜1.5mm程度に設定
されている。 In the case of this multilayer filter, when the gas flow passes through the honeycomb-shaped holes, the gas flow becomes a swirling flow, and dust with a large inertial force is collected by repeated collisions. Therefore, in the case of a multilayer filter, there is a close relationship between the spacing between the mesh filters and the dust collection efficiency, and the filter spacing is generally determined based on the characteristics of the dust collection efficiency with respect to the filter spacing. That is, when the filter spacing is narrowed, the gas flow is rapidly changed, so that the dust collection effect due to inertial force is large, and the dust collection efficiency is also high. Conversely, as the filter spacing increases, the change in gas flow weakens, and the dust collection effect drops sharply. For this reason, the filter spacing of multilayer filters is usually set to about 1.0 to 1.5 mm.
一方、フイルター内部の堆積ダストは集塵時の

ある。 On the other hand, the accumulated dust inside the filter partially blocks the area of the gas flow path during dust collection, causing a change in the flow velocity and sharply deteriorating the dust collection efficiency. Further, according to the relationship between flow velocity and filter pressure loss, as the flow velocity increases, the pressure loss of the filter increases, and the low pressure drop characteristic that is a characteristic of multilayer filters is impaired. Therefore, in the case of a multilayer filter, it is necessary to remove the dust so that the accumulated dust inside the filter does not deteriorate the dust collection efficiency or increase the pressure loss.

る。Problems to be Solved by the Invention Vibration methods and water washing methods are known as methods for removing dust from the multilayer filter.
The vibration method, in which the filter is mechanically vibrated to remove dust, is effective and widely used. As an example of this vibration method is shown in FIG. 5, a dust remover 13 installed opposite the dust collection surface of a multilayer filter 1 housed in a filter case 12 repeatedly moves back and forth to impart filter vibration. The principle is that the spacing between the laminated mesh filters increases due to the elasticity of the filter itself, and the dust is brushed off. This method of brushing off dust by widening the interval between the filters has the advantage of being able to effectively brush off the dust adhering to the surface and the accumulated dust inside, but since the dust duster 13 directly touches the dust collecting surface, As shown in Fig. 6, the dust 13 that has been blown off accumulates at the bottom of the filter case 12, making it difficult to widen the gap between the filters, and the dust-containing fluid easily blows through as shown by the arrow, reducing the dust collection efficiency. Furthermore, since the scraper has many components and is a moving part, it is subject to significant wear and tear, resulting in high equipment costs.

欠点を有する。Means to solve the problem Furthermore, since conventional dust removal methods mainly used materials such as cloth or paper that are relatively easy to apply vibrations to, the dust removal method is performed by forming honeycomb-shaped holes in a thin metal plate. A multilayer filter formed by laminating a plurality of mesh filters has the disadvantage that it cannot be applied in a straight line.

を特徴とするものである。 The above-mentioned drawbacks of the conventional method of applying vibration to a multilayer filter of the present invention to widen the filter spacing and brushing off dust, namely, damage to the filter, malfunction of spreading the filter due to dust accumulation, and blow-through of the dust-containing fluid. This was done to solve the problem of equipment costs, and as a means to do so, a multilayer filter made by laminating multiple mesh filters was suspended from the top without being housed in a case, and the filter was held down. It is characterized by repeating the action of spreading the multilayer filter in a widening shape and the action of fixing it in an inclined state by moving toward and away from the multilayer filter.

む。 That is, the present invention provides a method for brushing off dust adhering to a multilayer filter constructed by laminating a plurality of mesh filters by widening the interval between the filters, the multilayer filter being suspended in an upper rotatable suspension manner, When dust is removed, the presser arm is separated, and the multilayer filter, which is fixed in an inclined state by the fixed guide and the presser arm, is rotated around the upper rotatable suspension part, and is gradually spread out to a vertical position. After that, the multilayer filter is fixed in an inclined position again using the presser arm, which is repeated, and since the method does not vibrate by contacting the dust collection surface of the filter, there is no damage to the dust collection surface of the filter. In addition, since the filter is not housed in a filter case, dust does not accumulate inside the case, and blow-by of dust-containing fluid is reduced, and the structure is simple.

With G1 blocked, the filter presser 8 is rotated about the shaft 9 against the biasing force of the weight 11 to release the filter presser force. Multilayer filter 1
When the holding force is released, the bracket 2 rotates around the shaft 4 and returns to the horizontal state as shown in FIG. 3b, and at the same time each mesh filter 1-1
Due to the spacer 7 interposed between them and the elasticity of the filter itself, the multilayer filter 1 spreads out into a hem shape, so that each mesh filter 1-
1 gap widens. Through this operation, the dust adhering to the filter surface and the internally adhering dust are brushed off, and the removed internally adhering dust falls through the gaps between the filters. Note that by repeating pressing and releasing the multilayer filter 1 several times, the attached dust can be completely brushed off.

る。Effects of the Invention As explained above, the method of the present invention is a method in which a multilayer filter is not housed in a filter case, but suspended from the top, and the distance between each mesh filter is widened by moving the filter holder toward and away from the filter. Because of this, it has the effect of significantly reducing damage to the dust collection surface of the filter compared to the conventional method of applying mechanical vibration to widen the filter spacing, and also reduces damage to the filter dust collection surface caused by dust being dusted off and accumulating inside the case. This eliminates problems such as malfunctions and blow-through of dust-containing fluid, and improves dust collection efficiency. Furthermore, since a filter case is not used, the dust collection area can be expanded accordingly, improving dust collection performance.In addition, the mechanism for increasing the filter spacing is simplified, which reduces equipment costs and repair costs. .
