Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a filter in a so-called dust collector such as an air cleaner, a mist collector, or a pollutant separator. This invention relates to an impingement type filter that separates and collects pollutants by separating and collecting dust.

(Prior art) Generally, filters such as dust collectors have removal methods that utilize gravity, inertia, filtration, cleaning, charging effects, etc., and the method is selected from these various methods depending on the purpose of air cleaning. It has been adopted.

Conventionally, when contaminated air contains liquid substances such as oil or moisture, an impingement type filter has been used that hits the contaminated air against an impingement plate to separate and fall the contaminants, producing clean air. There is.

(Problems to be Solved by the Invention) Although clean air can be obtained to some extent with such conventional techniques, there is a problem in that the removal efficiency is poor.

For example, it may be necessary to accelerate contaminated air to increase the impact force, or it may be necessary to use it in conjunction with other filters, or
There is a problem in that multiple stage filters must be installed and dust must be collected multiple times.

That is, the present invention was made for the purpose of providing a compact impingement filter with high removal efficiency.

(Means for Solving the Problems) In order to solve these problems, this invention provides an impingement type filter that converts contaminated air into clean air by impinging on at least the collision surface 3 of the collision plate 2. , there is provided a collision type filter characterized in that particulate matter 4 is attached to the collision surface 3.

In the above configuration, the granules 4 may be crushed stones.

In this case, the collision surface 3 can be easily formed into an irregular uneven shape.

Further, in the above configuration, the granular material 4 may be sand.

In this case, it is easy to implement and can be provided at low cost.

Furthermore, in the above configuration, the granules 4 can be made large enough to pass through a mesh of 5 to 12 meshes.

In this case, the removal efficiency can be further improved.

Furthermore, in the above configuration, the particulate matter 4 can be attached by placing the paint on the collision surface 3 and then applying the paint again.

In this case, the particulate matter 4 can be easily attached.

Furthermore, in the above configuration, the particulate matter 4 can be attached by applying an adhesive to the collision surface 3 and then spraying it.

In this case, the particulate matter 4 can be easily and firmly attached.

(effect) The above technical means works as follows.

When contaminated air hits the collision surface 3, each particle of the contaminated air is dispersed in multiple directions (separating connections between particles) and removed.

In other words, while the collision surface of conventional collision filters diffuses particles solely by the impact force of impacting a flat surface, the present invention applies the impact force in multiple directions, making it easier to separate particles from each other.

In other words, in the conventional system, even if contaminated air hits the collision surface, the airflow becomes rectified and diffuses (diffuses along the collision surface); The airflow that hits the surface 3 becomes a turbulent flow due to the respective particles 4 and is diffused (diffused in multiple directions with respect to the collision surface).

(Example) An example of this invention will be explained with reference to the drawings. Figure 1 is a cross-sectional view of the device used in a dust collector;

A second frame 8 is formed by being fitted into the first frame 7.

The first frame 7 is provided with a plurality of inlet plates 5 (six sets in the drawing) each consisting of a pair of inlet inclined surfaces whose widths gradually become smaller and an inlet linear surface continuous therewith.

Note that, except for the inflow plates 5 at both ends, the other inflow plates 5 are integrally formed with adjacent inflow plates 5,
Forms a part of the first frame 7, and the frame 7
It makes it easy to install.

The second frame 8 includes a first collision surface 3a, an inverted inclined surface 6 which is continuous to both ends of the collision surface 3a and gradually becomes wider, and a second collision surface which is continuous to each of the inclined surfaces 6 and whose width becomes gradually smaller. The collision plate 2 is arranged such that when the second frame 8 is fitted to the first frame 7, the collision plate 2 is formed on the straight inflow surface of the inflow plate 5. The first collision surface 3a is made to correspond to the first collision surface 3a, and the first collision surface 3a is attached with an appropriate distance between the straight surface and the collision surface 3a.

Numeral 4 is a granular material made of crushed stone, and the granular material 4 is attached to the first and second collision surfaces 3a and 3b, which are the collision surfaces 3 of the collision plate 2, and the reverse slope surface 6. There is.

The above adhesion occurs after the collision plate 2 is coated with particles 4.
is placed on the collision surface 3a or the like, paint is applied again on top of the paint, and the paint is then dried to be fixed.

Note that the present invention is not limited to the above-mentioned embodiments; for example, granules may be attached to the front and/or back of the inflow plate, and the size and size of the granules may be adjusted depending on the part to which they are attached. Any combination of shapes or materials may be used.

(Effects of the invention) As explained above, the present invention has a simple structure that allows for efficient cleaning at low cost.Due to its structure, even if contaminated air containing oil etc. is cleaned, there will be no clogging. It is easy to maintain and manage as it has excellent durability.

Furthermore, since the removal efficiency is improved, the filter can be made smaller, the number of stages can be reduced, and maintenance of the auxiliary slip-type filter becomes easier.
