Abstract

PURPOSE:To obtain an effective dust collector by providing honeycomb-shaped filter elements having a large number of small holes in a frame body in an inclined state against the flow of a fluid and by arranging a plurality of said elements in series in the direction of flow of the fluid. CONSTITUTION:The filter elements B1 are arranged in series in the frame body 10, and provided in an inclined state alternately on right and left to change each flow of the fluid F toward the upward or downward direction and fixed by mounting members 16. Accordingly, every time the flow F passes through an element small hole 15 of each filter element B1, the flow direction is changed toward the upward or downward direction by a prescribed angle with respect to the direction of the length of the frame body 10, thus, the fluid F collides against the cell-wall of the filter element B1 of the next step.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dust collection device that collects dust particles in a fluid using a honeycomb filter mainly made of ceramics.

In recent years, various devices for removing dust contained in fluids have been developed and put into practical use as a pollution control measure such as air pollution prevention. It is known that the material uses a honeycomb-shaped material that is less likely to become clogged.

By the way, the present inventor tested using a honeycomb-shaped filtration material.
As shown in Figure 1, the dust 1 that is to settle is deposited only in the vicinity of the inlet 2 of the filter medium, and the other parts, especially the vicinity of the outlet 3, are not contaminated by dust and remain as they were in the initial state. It was found that most of the dust was not collected. This is because the honeycomb filtration material has a long slenderness in the direction of the diaphragm of the fluid F, so when the fluid F passes through the honeycomb filtration material, it becomes slanted, and as a result, the inlet It has been found that in areas other than around 2, the fluid F hits the filter wall and passes through as it is, and the filtration ability is hardly exhibited.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a dust collection device that has an extremely high dust collection effect and has a structure that lasts for many years.

In order to achieve the above object, the present invention provides a honeycomb-shaped filtration element having a large number of element holes in a frame at an angle with respect to the flow of the fluid F, and the filtration element has a flow rate. By arranging a plurality of filtration elements in series in the direction of flow, and causing the fluid F to flow through the small holes of each filtration element, the flow of the fluid is changed and the dust collides with each passing element. It was designed to be collected.

An embodiment of the present invention will be described below based on one drawing.

In FIGS. 1 to 10, 10 is a frame body, and as a larger means for disturbing the flow of fluid F within this frame body 10, various filtration elements A 1 g A @ , A, *
B1 or guide vane Ct=l slip suppression plate is the frame body 10
are provided in appropriate combinations.

Each of the above-mentioned filtration elements A, -, A, , has a honeycomb structure formed of ceramics.

This T11 filtration element A has a large number of element pores (cells) 11 with the same shape and surface.
Further, the filter element is formed with element holes (cells) 12 having a different shape and cross section from the element holes 11 of the protection element. Furthermore, the filter element A has a cross-sectional shape having element pores (cells) 13 having a different cell density per unit area than the element pores 11 of the filtration element.

In FIG. 1, the filtration elements AI are arranged in one row in the frame 10 and fixed by the mounting member 14, and the adjacent filtration elements Element small hole 11
The adjacent 1iMd elements A1 are arranged so that the phase of each element is shifted in the vertical direction so that the @ lines of the element holes 11 of the adjacent 1iMd elements A1 do not coincide with each other. As a result, 1 of the top 491%
Fluid F, which has been filtered by the THL filtration element 1 in the first stage and has been rectified to some extent, is forcibly passed to the second filtration element.

The flow of fluid F is disturbed by colliding with the cell wall of
2nd stage smallpox element person, n! The fluid F, which has been hit by the enemy and has become anti-rectified to some extent, collides with the cell dragon of the third-stage retreating element, and the flow of the fluid F is disturbed.

In addition, in FIG. 2, filtration element A of 21 solids,
With one filter element 18 sandwiched between them, there are two 4-) t! 4 elements A, in a combination state sandwiched between each filtration element) (AI, λB
, Al ) , (AH, λ5-At) are the frame 1
0 and are fixed by the mounting member 14, so that in FIGS. 2 and 3, the first stage filtration element on the upstream side is
The fluid F that has been made into a flow is passed through the second stage filtration element A,
The fluid F that collides with the cell wall of A and is rectified to some extent by the second stage filtration element A collides with the cell wall of the third stage filtration element A, and both fluid F
The flow is sequentially disturbed.

The above-mentioned filtration element B1 includes each of the above-mentioned filtration elements A1
, person 2. Like A, it is made of four honeycomb structures made of ceramics, and a large number of small element holes (cells) 15 having the same cross-section are formed. In FIG. 4, filtration elements B1 of 31 solids are arranged in series in the frame lO, and each of the filtration elements B1 of 1
U) In order to vary the filtration element upward or downward, the filter elements are provided tilted alternately to the left and right and are fixed by a mounting member 16, so that the element hole 15 of each filter element B can be Each time the fluid F passes through, the direction in which the fluid F flows is changed upward or downward by a predetermined angle with respect to the length direction of the frame 10 (horizontal direction in FIG. The fluid F collides with the cell wall. Note that the inclination angles of the filtration element pores are set appropriately, and the element pores 15 of the filtration element B are not only of a single size but also of a mixture of various sizes. Also, each filter element B1. For B1 and B, the phases of the filtration elements that are in momentary contact may be shifted by 15 points in front of the element small holes, and these different filtration elements may be used in a continuous arrangement.

The guide vane CI is provided on the upstream side of the filtration element A1 (see FIG.
3 (not shown) or filtration element B1
(see Figure 6), which generates a swirling flow in the dust-containing fluid F.
This allows the fluid F to efficiently collide with the cell walls of the cell. Note that this guide vane C1 may be rotatably provided to arbitrarily control the flow direction of the fluid F.

The flow restriction plate may be placed on the upstream side of the filter element A1 (see FIG. 7) or on each filter element 3. A,
(not shown) or on the upstream side of the filtration membrane (see Fig. 8), and the solid part 17
1 is provided to reduce the linear flow hole area, and when the fluid F passes through the flow hole 17 of this flow suppression plate, the fluid F is compressed and passes through the flow hole 17 with an increased flow velocity. This disturbs the flow of fluid F.

Next, each of the above filtration elements 1 g A @ s
The operation of this dust collector will be explained using an example in which A @pB, or a guide vane C1, and a flow suppressing plate are combined.

FIG. 9 shows an arrangement in which the combination unit of the filter element B shown in FIG. 5 and the guide vane C1 and the combination unit of the filter element B and the guide vane C1 shown in FIG. 6 are arranged alternately. When the fluid F8 is made to flow through this, first, a swirling flow is generated in the fluid F by the guide vane C1 installed on the upstream side of the first stage a filter element L'At, and then the above-mentioned filtration element , in order to bring the swirled fluid F into contact with the above filtered elmmen) A t
collides with the cell wall of the element small hole 11, and the fluid F
The dust particles inside are deposited on the cell walls. On the other hand, the fluid F, which has passed through the first-stage filtration element and has been rectified to some extent, flows on the upstream side of the second-stage filtration element before reaching the second-stage filtration element. guide vane C
1 and collides with the cell wall of the element small hole 11 of the filter element A1. On this occasion,
The position of the element hole 11 of the second-stage u-filtering element A1 is vertically shifted from the phase of the element hole 11 position of the first-stage filtration element A1, and the action of the guide vane C1. are superimposed on each other, and the fluid F collides with the cell wall of the second-stage filtration element, so that the dust particles in the fluid F efficiently adhere to the cell wall.

Next, the fluid F that has passed through the second-stage filtration element A1 passes through the third-stage filtration element B, which is installed at an angle.
After being rotated by the upstream guide vane C1 of No. 1, it reaches the filter element B1. At this time, due to the fact that the third stage filtration element Bt is inclined and the guide vane C1, the fluid F is transferred to the third stage filtration element B.
The dust particles in the fluid F effectively collide toward the cell wall of No. 1, and the dust particles in the fluid F adhere to the cell wall.

Subsequently, the fluid F that has passed through the third stage filtration element B advances obliquely with respect to the length direction of the frame IO (in the upward direction in FIG. 9).
, 4Jbl after being swiveled further to change direction by guide vane C1.

Since the filter element B of the filter element B and 4ζ are different from each other, the fluid F collides with the cell wall of the filter element B1 in a disturbed state, and the dust particles in the fluid F collide with the cell wall of the filter element B1.
It adheres to the cell wall of 1.

Furthermore, the fourth stage filter element 8. The fluid F that has passed through is changed in its flow direction by the cough filtration element B1, and is swirled by the guide vane C0 before reaching the fifth stage engaging element A1, so that the flow is disturbed. The fluid F impinges against the cell walls of the filtration element, and dust particles adhere to the cell walls.

Next, the fluid F, which has been rectified to some extent by passing through the 5th stage filter element, is changed direction by the guide vane C0 and reaches the 6th stage filter element A1. Due to the fact that the phase of the vertical position of the element small holes 11 of the filter element A1 of the stage is shifted and the guide vane C1, the body F is
It effectively collides with the cell wall of the sixth stage filtration element, and the dust particles adhere to the cell wall. Then, the fluid F that has passed through the sixth stage filtration element A1 flows downstream in a clean state with dust removed.

In addition, Fig. 1θ is the same as Fig. 9 in which a flow suppressing plate is provided instead of the guide vane C5, and when the fluid F is made to flow through this, the fluid F is compressed by each flow suppressing plate. In addition, the fluid F is made to change its flow direction by the filtration filter Bt in the third and fourth stages, and increases the flow velocity and passes through the flow hole 17. Due to the synergistic effect that the flow of the fluid F is disturbed by the vertical shift in the phase of the position of each element small hole 11 of the filtration element A1 and the fifth and sixth stage filtration elements A1, each filtration element Person 2. The fluid F efficiently collides with the cell wall of the element small hole 11.15 of B1, and dust particles are captured.

In addition, the length of the cell wall of each of the above-mentioned filtration elements A, , A, , A is shortened to such an extent that the dust-trapping ability of the cell wall is not affected, and the rectification of the fluid F passing through the inside is made short. It is preferable to suppress the Further, the phase shift of the element holes 11 of adjacent filter elements may be shifted in the left-right direction. Furthermore, in the above example, each of the filter elements A, , A, , A8 . B.

As explained above, the present invention includes a honeycomb-shaped filtration element having a large number of small element holes in a frame, which is inclined with respect to a direction perpendicular to the flow of the fluid, and a filtration element through which the fluid flows. Since multiple filtration elements are arranged in series in each direction, the fluid flows through the small holes of each filtration element, changing the flow of the fluid and causing the dust to collide with each filtration element. , dust can be captured efficiently. Therefore.
