DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG.
A large number of exhaust ports 5 for connecting to an exhaust hood 4 are provided on the ceiling 3 and an exhaust unit 8 is connected to a wall surface 7 of the ceiling back 6, so that the entire ceiling 6 serves as an exhaust air path.

The exhaust ports 5 are formed to be freely openable and closable. Specifically, a lid (not shown) is detachably provided at the exhaust port 5, and the lid is closed and connected to the exhaust hood 4 via a first stainless steel duct 9. There are things.

The exhaust hood 4 is provided so as to cover just above the combustion equipment 14 installed in the room 2.

An exhaust port 5 connected to the exhaust hood 4
Is provided with an exhaust amount adjustment damper 10 for adjusting the exhaust amount by changing the opening degree of the exhaust port 5.

The exhaust amount adjusting damper 10 is provided with a shutter 11 that can be opened and closed at the exhaust port 5, and the shutter 11 can open the exhaust port 5 to an arbitrary opening. I have. And the displacement adjustment damper 1
Numeral 0 controls the flow rate of the exhaust gas sucked through the first duct 9 and sends it to the ceiling 6.

The exhaust unit 8 is composed of a large sirocco fan, and is connected to the wall 7 of the ceiling 6 via a second duct 12 made of stainless steel.

The exhaust unit 8 is determined so as to have a capacity to meet the required displacement. If the amount of heat is increased due to a change in a production line (not shown), the exhaust unit 8 can be installed and dealt with. Has become.

The inside of the ceiling back 6 is covered with a stainless steel plate (not shown) so that exhaust gas is not directly applied to building materials.

The wall of the room 2 is provided with an air supply device 13 for purifying and supplying outside air to the room 2. The air supply device and the exhaust gas are balanced so that the exhaust device 1 can be efficiently used. It is designed to operate.

Next, the operation will be described.

When the exhaust device 8 is driven and a large number of combustion devices 14 are used in the room 2, the exhaust gas generated from the combustion devices 14 passes through the first hood 4 via the exhaust hood 4 provided on each combustion device 14. The air is sucked into the interior 9 and flows into the space 6 above the ceiling.

At this time, since the exhaust amount adjustment damper 10 provided in the exhaust port 5 is adjusted in exhaust balance in advance, the exhaust gas generated in each combustion device 14 is sucked up to the ceiling 6 without any excess or shortage.

All the exhaust gas sucked into the ceiling 6 is sucked into the exhaust unit 8 through the second duct 12 and discharged outside.

When the position of the heat source is changed due to a change in the production line or the like, the exhaust hood 4 and the first duct 9 at the position where the heat source has disappeared are removed from the exhaust port 5 and moved to the position of the moved heat source.

At this time, the exhaust port 5 from which the first duct 9 has been removed is covered and completely closed by a cover, and the exhaust port 5 closest to the heat source is closed.
Among them, the lid of the unused exhaust port 5 is removed and the exhaust port 5 is opened. Then, the first duct 9 is attached to the exhaust port 5, and the exhaust hood 4 is attached to the first duct 9.
The first duct 9 is attached so as to have a height of 1 meter or less directly above the heat source.

Thereafter, the exhaust balance is adjusted. The adjustment of the exhaust balance is performed by adjusting the opening of the shutter 11 of each of the exhaust amount adjustment dampers 10. When the opening of the shutter 11 of the displacement adjustment damper 10 is increased,
The amount of exhaust from the exhaust port 5 having an increased opening increases.
Then, the amount of exhaust from the other exhaust port 5 becomes relatively small.

When the number of heat sources increases, an unused exhaust port 5 among the exhaust ports 5 closest to the heat source is opened, a new first duct 9 is attached to the exhaust port 5, and a new first duct 9 is attached to the first duct 9. Attach a new exhaust hood 4.

Then, the exhaust balance is adjusted in the same procedure as described above. If the overall displacement is insufficient, a new exhaust unit 8 is added. The addition of the exhaust unit 8 is performed by connecting a new second duct 12 to the wall surface 7 of the ceiling space 6 and connecting the new exhaust unit 8 to the second duct 12.

When the amount of heat of the heat source is changed, it is only necessary to adjust the exhaust balance and add a new exhaust unit 8 if necessary.

As described above, a large number of exhaust ports 5 for connecting to the exhaust hood 4 are provided in the ceiling 3 of the room 2, the exhaust unit 8 is connected to the wall surface 7 of the ceiling 6, and the entire ceiling 6 is exhausted. Because of the air passage, there is no need to run complicated piping, and even when the combustion equipment 14 is moved, the exhaust hood 4
In the case where the exhaust device 1 can be easily and inexpensively supported simply by changing the connection position of the first duct 9 and the opening of the exhaust adjustment damper provided in the exhaust port 5 and further increasing the number of heat sources In addition, the forced exhaust can be freely performed by increasing the exhaust hood 4 and the first duct 9.

Further, since it is easy to respond to a change in the production line or a need to locally increase the exhaust air volume, heat or heat is applied to a part of the room.
The working environment can be easily and inexpensively improved without stagnation of steam, fumes, dust, odor and the like.

Further, since each exhaust port 5 is formed to be openable and closable, the first duct 9 can be easily removed and closed or connected, and the position of the exhaust hood 4 can be easily changed.

Since the exhaust opening 5 is provided with the exhaust amount adjusting damper 10 for adjusting the exhaust amount by changing the opening, the exhaust amount of each exhaust hood 4 can be easily adjusted. The exhaust balance can be easily adjusted without performing inverter control on the exhaust gas 8.

When the exhaust capacity of the exhaust unit 8 is insufficient, it is only necessary to add two or three exhaust units 8 and the capacity shortage and the balance shortage can be easily solved.

The exhaust 8 is connected to the wall 7 of the ceiling 6 via the second duct 12, but is not limited to this. The exhaust 8 is connected to the roof 15 and exhaust gas in the ceiling 6 is removed. Suction may be used.

Various sensors (not shown) such as a temperature sensor and a humidity sensor are provided for each of the displacement adjusting dampers 10.
