[Conventional technology]

In addition to maintaining a good working environment within the factory building, it also prevents contaminated air from being vented to the outside. A mist collector cleans the air to prevent it from leaking through the air ducts. things are being done. Conventionally, mist collectors include centrifugal separators, filter separators, and air filters. There are separators using veneers, etc. Among these, centrifuges rotate contaminated air at high speed, The mist is attached to and removed from the inner peripheral wall by centrifugal force, but the droplets are rotated at high speed. Because of this, it tends to scatter again and is inefficient. Also, a mist separator using a filter. has high separation performance by selecting an appropriate filter, but fine solid particles It is easy for fumes to adhere to the filter and cause it to become clogged, and when cleaning or replacing the filter, Maintenance is complicated and running costs are high. Separator using air collision plate , air containing mist is sent through a curved passage and forced through it. This technology takes advantage of the phenomenon in which mist is separated when it collides with a road wall, and is It is less effective when the water contains fine solid particles, but it contains a lot of mist. In some cases, solids and particles can be removed along with the mist, and there is no risk of clogging. It has the advantage of being maintenance free and can be used for a long time.

0003 For example, a mist controller using a collision plate disclosed in Japanese Utility Model Application Publication No. 62-106614 The vector is shown in FIGS. 3 and 4. Figure 3 is a side cross-sectional view, showing the weir plate standing on the frame 2. A bottom plate 4 having an opening 7 extends between 3A and 3B. The bottom plate 4 has a bending A collision plate 5 is provided upright. FIG. 4 is a view taken along arrow II in FIG. is made of bent plate material, and a plurality of collision plates 5 are arranged in parallel to allow air to circulate between each plate. The air flows as shown by arrows A and a. Mi contained in the air The air (moisture) is forced to flow between the collision plates 5 by bending as shown by arrow a. The liquid collides with the collision plate 5, liquefies, drips, passes through the opening 7, and accumulates in the chamber 6. In addition, cough The plates 3A and 3B are designed to prevent water droplets on the bottom plate 4 from being scattered again by the air flow. Acts as a weir for airflow.

[Problem that the idea aims to solve]

However, the conventional mist collector using the above-mentioned collision plate does not allow the mist to drip onto the bottom plate. Although measures are taken to install a weir plate to prevent water droplets from scattering again, It is inevitable that the falling water droplets will be exposed to air currents and re-splattered. Also Since the collision plates are installed parallel to each other, the air flows relatively smoothly and sufficient collision occurs. mist is not generated, and the mist is not collected sufficiently.

[0005] This invention was made to solve the above-mentioned problems, and it It has a collision plate where the air collides violently, and the air also flows downward against the collision plate. This ensures that even if water droplets formed on the collision plate are re-splattered by the air, they will not escape to the outside. The purpose is to provide a new mist collector.

[0006]

[Means to solve the problem]

In order to achieve the above purpose, the present invention collides mist in the air with a collision plate to prevent mist. In a mist collector that collects and removes mist, air is connected to one end of the mist collector body. In addition to providing an air inlet and an air outlet at the other end, air outlets are arranged alternately inside the mist collector body. Divided into multiple communicating chambers by hanging plates and rising plates, air flows downward and upward. It is configured so that the air flows alternately with the direction flow, and the cross section is approximately An angle material that is V-shaped and has a drop hole at the bottom of the V is made so that the bottom of the V is facing downward. A large number of angle members are provided so that the longitudinal direction thereof is gently inclined to form a collision plate, In addition, the hanging plate is bent at the fold on the side of the chamber where air flows downward to form a diaphragm. In addition, the uppermost stage of the angle material and the tank part at the bottom of the mist collector body. A mat made of open foam sponge is placed on each mesh board at the top of the space. It has been done.

[0007]

[Effect]

Based on the above configuration, the air containing mist flows upward by the hanging plate and the rising plate. The direction of the flow changes alternately with the downward flow. And in the part where the flow is downward Since many angle members with a V-shaped cross section are lined up, air violently collides with the angle members. to make the mist aggregate on the surface of the angle material. The aggregated mist becomes water droplets and It falls through the hole in the V-shaped bottom of the wood, but at this time the air flow is downward. The water droplets are carried to the bottom of the mist collector body, and the air flow changes upward from there. However, water droplets fall due to inertia and do not scatter again. Connected to the top of the angle material. By providing a post-foaming sponge mat, the mist is evenly dispersed and directed towards the angle material. If installed at the bottom of the mist collector body, the mist carried by the air flow can also be installed at the bottom of the mist collector body. Water droplets are absorbed and do not bounce back, making it even more efficient.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. Figure 1 shows the mist according to the present invention. It is a sectional view of the collector, and one end of the mist collector main body 10 has an air inlet 15. However, an air outlet 16 is provided at the other end, and air is supplied from the air inlet 15 (not shown). It is forcibly fed in by a rolling fan, etc.

[0009] The inside of the mist collector main body 10 is divided into four parts by hanging plates 17, 18 and a rising plate 19. It is divided into two chambers, and the air is supplied to the lower end of the hanging plate 17, the upper end of the rising plate 19, and the lower end of the hanging plate 18. It bends at the bottom and flows like an arrow. The hanging plates 17 and 18 allow air to flow below them. It has folded parts 17a and 18a, respectively, so that the width becomes narrower, and is narrowed at the bottom. . Therefore, the air is constricted near the lower ends of the hanging plates 17 and 18, and the downward flow speed increases. At the same time, the water droplets move straight downward and accelerate, and the air that reverses and rises up the passage. As the area becomes wider, the flow velocity slows down, making it difficult for re-splattered water droplets to rise. . In each room where air flows downward, a large number of angle members 13 are installed in the longitudinal direction. It is set at a slight incline.

0010 FIG. 2 shows a sectional view taken along line AA in FIG. Place the angle material 13 at the bottom of the V shape. It has a hole 13a, which serves as a hole for water droplets to fall. As shown by the arrow in Figure 2, air is The mist collides with the shoulder part of the angle material 13 and changes direction drastically, causing the mist to aggregate and form water droplets. and is collected at the bottom of the V-shape of the angle member 13. Then, the length of the angle material 13 It flows along a gentle slope in the hand direction and eventually falls through the hole 13a.

[0011] In this embodiment, four chambers are formed by two hanging plates 17 and 18 and one rising plate 19. However, it is also possible to provide a larger number of hanging plates and rising plates. Also, the angle An open-cell sponge mat 11 is provided on the top of the material 13, and the mist is applied to the angle material 1. 3 so that it is evenly distributed. Tank at the bottom of the mist collector main body 10 A mesh board 20 made of a wire mesh or a board with many holes is placed above the space 21 that serves as a section. There is also an open-cell sponge mat 14 on top of it, which collects fallen water droplets. It absorbs and prevents re-scattering due to rebound. Water that has accumulated in space 21 is drained It is discharged from port 22 as appropriate.

0012

[Effect of the idea]

As explained above, according to the present invention, the air containing mist is distributed at a V-shaped angle. Since it collides violently with the collision plate made of wood, the mist separation effect is high. Also, air Since the collision plate is installed in a position where the mist flows downward, the water droplets formed by the agglomeration of the mist are weighed down. Because the force action and the wind action act in the same direction, it is difficult to scatter again and In addition, the lower end of the chamber in which the air flows downward is constricted, so the airflow speed is rapid. When the air turns around and rises, the flow speed of the air slows down, so the falling water droplets is accelerated and collected in the lower tank part by inertia, and the scattered water droplets are It becomes difficult to rise. In addition, the mist is dispersed by the mat on the top of the angle material. The water droplets are distributed evenly to one part, and the water droplets are Since it adheres and is absorbed by the jet, it does not bounce back and prevents re-scattering.
