Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a duct panel in which an electrostatic precipitator and a duct are incorporated in the internal hollow part of a partition wall panel (hereinafter referred to as the panel).

The electrostatic precipitator is a newly developed, slim, vertically elongated device that is built into a hollow part of the panel. The duct (ventilation cavity) is
It consists of an electric precipitator sandwiched inside the panel.
The intake port and the exhaust port are also provided vertically from the top of the panel to the bottom, facing one side of the room.

Conventionally, indoor air purification devices using electrostatic precipitators have been divided into large-scale air-conditioning systems with centralized control systems that cover the entire building, and small-sized indoor air purifiers that can be installed indoors.

Although the former large-scale air conditioning system is very effective, the installation and running costs are significant. On the other hand, it is not possible to sufficiently meet the demand for air purification on a room-by-room basis in special rooms with dirty air. Therefore, the latter smaller size is considered to be appropriate for cleaning the air in a single room. However, the use of a small electrostatic precipitator for each room is not widely used. This is due to the fact that installing machines that fit the room will make the indoor space smaller, the sound of the motor for forced ventilation will be transmitted directly into the room, creating noise, and it will be expensive.

Also, ducts are used for air conditioning systems,
There were no built-in panels, and even though there were glazed windows for natural ventilation and exhaust windows with exhaust fans attached, they were not ducts, but rather windows for ventilation on the front and rear sides of the panels. Ventilation cavities used as ducts moved air from one room to another, with panels separating them. These methods not only cannot meet the demand for air purification on a room-by-room basis, but also require heating and cooling of rooms, sterilization (sterilization)
This was to bring uncontrolled air from other rooms into the room.

For this reason, the applicant has developed a system (hereinafter referred to as the "A duct panel") that incorporates an electrostatic precipitator, provides a duct inside the panel, installs intake and exhaust ports on the top and bottom of the panel, and opens them to one side of the room. However, the present invention can be called a sister product of the A duct panel.

However, in the A duct panel, the ventilation in the duct flows from top to bottom, purifying the air in the upper layer and returning it to the air in the lower layer, which can also be called a conventional circulation method. It is. The present invention works on all layers above and below the layer of suspended particulates in the air, and is characterized by an electrostatic precipitator configured vertically in the vertical direction, and an intake and exhaust port.

Conventionally, for indoor suspended dust (fine particles),
It is said that it is desirable to point the inlet of the electrostatic precipitator near the location where the dust is generated. Under good observation conditions, dust particles can be divided into particles that are visible to the naked eye and particles that are invisible to the naked eye, with a diameter of 10 microns as the boundary, but dust as large as visible particles cannot rise to the upper part of the room due to the indoor air. A small amount, most of it, falls due to the stability of the air movement. On the other hand, invisible particles rise quickly and fall slowly, or remain suspended for a long period of time. It is said that suspended dust in a room forms a layer. For example, sand particles range from 100 microns to more than 1000 microns, coal dust from 1 micron to 100 microns, cigarette smoke from 0.01 microns to 1 micron, viruses from 0.1 to 0.005 or more, or dry milk spray from 0.1 to 100 microns. It becomes floating dust in a width of 10 microns. For this reason, for example, if you place the inlet of an electrostatic precipitator at the position of a smoker's mouth, the position of a medicine dispenser's hands, or the position of a pedestrian's shoes, most of the generated dust can be absorbed ( (at the electrode plate).

However, the cleaning effect of an electrostatic precipitator (passing through the electrode plate) is limited to measurable 0.3 microns.
It is said to be 70 to 75%, and it is not possible to capture all of the dust at the place where it is generated.

In addition, since the layers formed by the dust particles mentioned above are greatly different, it is necessary to position the intake port centering on the place where the dust particles are generated, or to place the upper intake (intake port) as in the example of the A duct panel. ), which utilizes natural air convection such as bottom discharge, but in one pattern, all suspended particles are quickly moved,
There is not enough material to be introduced into the electrostatic precipitator.

For this reason, the present invention opens a series of intake ports from the upper part of the panel (chamber) to the lower part, and similarly, exhausts the air in a series from the upper part to the lower part of the panel, thereby creating a laminar circulation of air and generating electricity. The effect is further increased by adopting a structure that leads to a dust collector, and housing the duct and electric dust collector within the panel.

As for the electric precipitator set vertically, a revolutionary slim model that is built into the panel width and does not require a fan (motor) has been developed. This has further increased its usability and contribution.

The present invention will be explained with reference to embodiments and drawings.
First, the configuration of the present invention will be described.

The duct panel 1 also includes a front plate 2 and a back plate 3 to form front and rear (front and back) parts. Top plate 2 and back plate 3
and are used by forming a hollow part between them and directly facing each other. The hollow portion has a duct width W.

On the top plate 2, an intake port 6 and an exhaust port 7 are formed on the left and right sides, with a mounting port 5 in the vertical center for allowing the vertically elongated electrostatic precipitator 4 to enter and exit, and all three are opened into vertically long windows. The back plate 3 is not provided with such an opening. The electrostatic precipitator 4 is configured to be vertically long, and is inserted and removed through the mounting opening 5, and is attached to the vertical center of the hollow part of the panel (the structure and mounting method of the electrostatic precipitator are not shown and are well known).

The upper and lower parts of the hollow portions of the front and back plates 2 and 3 are closed with intermediate frame members 8 and 8 made of horizontally elongated channel material to a width W of the duct, and the left and right end portions of the hollow portion are covered with longitudinally elongated channel material. The duct stud 9,
9 to form a duct. The duct studs 9, 9 have an inwardly elongated blowing surface portion 10,
10 are used to face each other, and the end line of the blowout surface portion 10 having an inwardly curved blowout surface is connected to the R end portion 12 of the left and right side ends (for example, the right side) of the top plate of the intake port 6 and the R end portion 12 of the top plate of the intake port 6 . Top plate left and right end side (for example, left side)
along the L end 14 of the channel material, and the legs 11, 11, which are opposite side pieces of the channel material, are placed on the front and back plates 2, 3.
are brought into contact with the back surfaces 13, 13 of, and connected and fixed to the upper and lower intermediate frame members 8, 8.

Although the duct stud 9 serves both as a closing material and a stud (stud) in the embodiment, it may also be used simply as a closing frame material.

With the above steps, the duct panel 1 is completed. Inside the duct panel 1, there is a duct 15 with a duct width and thickness W.
is formed, and is surrounded at the front and back (front and back) by the back surface 13 of the top plate 2 and the back surface 13 of the back plate 3, the top and bottom are closed and enclosed by the intermediate frame members 8, 8, and the duct studs 9, 9. The vertical sides (left and right) are closed and enclosed, and an electrostatic precipitator 4 is fixed in the vertical center of the duct 15 (electrical wiring is provided, but this is omitted as it is well known). Furthermore, three vertical windows, an intake port 6, a mounting port 5, and an exhaust port 7, are opened on the front side of the duct panel 1, and the tops thereof are covered with a decorative lid 16. A portion of the decorative lid 16 that covers the intake port 6 and the exhaust port 7 is provided with vertically long ventilation holes 17, 17, which are openings. Note that a decorative lid 16 that separately covers the intake port 6 and the exhaust port 7 may be used.

The duct panel 1 incorporating an electrostatic precipitator of the present invention includes:
As mentioned above, the configuration is extremely simple, and
It can be easily manufactured using ordinary panels regardless of time or whether one is skilled or unskilled, and the shape of the duct is also novel.

Next, the functions and effects of this duct panel 1 will be described. There are already inside the duct panel 1 on the left and right.
A duct 15 is formed that opens into the room, and when the power switch 18 inputs power to the electrostatic precipitator 4 and rotates the intake fan (not shown) to blow air toward the exhaust port 7, the intake air Forced air movement takes place in the duct 15 from the port 6 to the exhaust port 7, and the intake port 6 begins to suck in air from the room.

Air movement in forced ventilation is strongest in the straight direction from the fan, and generally, the narrower the duct width W, the stronger the propulsive force. The intake fan (built into or the same as the electrostatic precipitator 4) in the present invention directs the indoor air from the right side (intake port 6) to the left side (exhaust port 7), and directs the indoor air right sideways from top to bottom with almost the same force. The indoor air is moved in a straight line, and by the horizontally straight exhaust into the room and the horizontally straight intake in the upper and lower portions of the duct 15, a new laminar circulation movement is created in the room air. In other words, the flow of indoor air changes from the conventional vertical convection and circulation from warm (light) air to cold (heavy) air to one that is mainly based on horizontal (layer) circulation. This works effectively against the layer of suspended dust in the above-mentioned state.

Note that horizontal ventilation is also used for forced air in sterilization rooms.

Therefore, the duct width W of the present invention is as narrow as the so-called panel width, and plays a large role in straight forward ventilation. Compared to the A duct panel, approximately 4 to 5 times more straight exhaust force is obtained.

Now, from the ventilation hole 17 of the decorative lid 16,
The indoor air led to the first duct stud 9
is guided by the blowing surface portion 10 into the duct 15 and enters the electric field of the electrostatic precipitator 4.

Micron-sized particles contaminating the air are charged and instantly adsorbed to the electrode plate of the electrostatic precipitator 4. In this way, the air becomes clean, and the duct 15
The discharge is guided by following the outlet surface 10 of the other duct stud 9, passes through the exhaust port 7, and is returned to the room through another ventilation hole 17, and this circulation is repeated until one room is filled. Air purification of the unit is achieved.

The duct panel 1 of the present invention is also different from the upper intake and lower discharge effects of the sister invention A duct panel, and brings about a layered circulation of air in the room, reducing airborne particles, temperature differences, and forced ventilation force. Introducing indoor air into the intake port 6, which is biased due to size, etc.
It can be done evenly above and below, eliminating the average. Also, it can work more effectively than the A duct panel against smoke creeping on the floor during a fire.

It is effective to use a plurality of duct panels 1 of the present invention in one room, or to use them in combination with the A duct panel. Furthermore, it can be made into a small panel body, which can be carried around, inserted between walls, or suspended.
