Description

[Detailed description of the invention] This invention relates to a soot purification device that burns not only heavy oil, but also fibrous materials such as sawdust, planer shavings, and paper scraps (hereinafter referred to as paper scraps). To provide a simple device for purifying soot generated in a bathtub or the like that can be heated.

Traditionally, bathtubs and other structures have a flue and a chimney directly at the rear end of the combustion part. However, as the air rises with the air currents, cinders will scatter from the tip of the chimney into the outside air, contaminating the surrounding area, and in extreme cases, sparks may be scattered from the tip of the chimney along with soot, creating a risk of flames. Ta.

Therefore, in order to solve these problems, when burning paper scraps, etc., it is possible to weaken the suction of smoke into the flue and chimney, but this means that the fuel in the combustion section will not burn incompletely. This is not an ideal solution to the problem as it causes combustion and worsens the combustion.Also, spraying water etc. in the flue to purify the soot and smoke is not recommended at home or in public baths, etc. The equipment was too large and expensive to use, making it useless.

This idea consists of dividing a box-shaped device body with a large volume into upper and lower parts by a grate, and opening and communicating a flue that communicates with a combustion device for waste paper, etc. on the side of the device body above the grate. In addition, a flue is opened and connected to the side surface facing the above-mentioned side surface at a position below the fire grate to form a soot and smoke exhaust route, and a lid body that can be opened and closed is provided at the top of the device body to prevent the inside of the device body. A simple device that eliminates the above-mentioned drawbacks by configuring it so that it can be easily inspected, repaired, or cleaned, and that can purify soot and smoke without reducing the strength of smoke suction into flues and chimneys. An embodiment of this invention will be described in detail with reference to the accompanying drawings.
The structure is such that one end of a flue 2 provided in a bathtub or the like is attached to the upper side of a device body 1 formed into a box shape with a block or the like, and the flue 2 is opened into the device body 1. A starting end of a chimney 3 is opened at a position opposite to the flue 2 at the lower side of the other side of the device body 1, and a ridge 9 is provided at an intermediate position on the inner wall of the device main body 1, and preferably, the size of the grid is about 1 cm2.
The soot and smoke introduced into the main body 1 of the device from the flue 2 passes through the grate 4 from above to below and is discharged from the chimney 3. be.

Further, the upper part of the apparatus main body 1 is open, and a lid body 5 is provided so as to be freely openable and closable.
At the bottom of the main body 1, there is formed an ash kettle recovery part 6 located below the position where the starting end of the chimney 3 opens. The recovery section 6 is provided with a door 7, and is formed so that the ash 8 accumulated inside can be easily taken out.

Since the soot and smoke purification device according to this invention is configured as described above, the soot and smoke discharged from the flue 2 into the device body 1 is directed downward while significantly reducing the flow velocity within the device body 1 which has a large volume. In the middle of the flow, the grate 4 acts to rectify the flow, and the excess flow is almost completely eliminated.

Therefore, cinders such as paper scraps mixed in soot and smoke will quietly move downward due to the downward flow of soot and the weight of the cinders themselves. As a result, the downward movement due to its own weight is accelerated.

The soot and smoke that has descended in this way flows into the chimney that opens on the lower side of the device main body 1, rises, and is sequentially discharged to the outside, but since the cinders have a large inertial force, they change direction and almost ride the flow of the soot and smoke. Since it quietly lands on the bottom of the main body 1 of the apparatus without any problems, burnt residue such as paper waste can be efficiently removed.

Moreover, according to this device, the intensity of soot and smoke sucked by the flue 2 and chimney 3 is almost the same as when no device is installed, and by installing the device of the present invention, There is no change in combustion in the area, and it can be installed extremely easily without modifying existing bath pots, etc. Furthermore, the grate 4 can be replaced,
If the inside of the main body 1 is removed, the inside of the main body 1 can be cleaned easily by opening the upper lid 5.

Furthermore, since the flow velocity inside the device main body 1 is extremely low as described above, the static pressure increases, and therefore the lid body 5
There is no need to create a complicated structure at the joint between the main body 1 and the main body 1 to improve airtightness.

As mentioned above, this device has an extremely simple structure, can be installed at low cost, and can efficiently purify soot and smoke, making it an ideal soot and smoke purification device for bathtubs in homes and public baths. And its practical value is extremely great.
