Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas cooling device whose purpose is to cool high-temperature gas such as hot air, steam, and flue gas.

An embodiment of the present invention will be described with reference to the drawings. A bottom plate 2 is fixed to the lower surface of a cylindrical outer wall 1, and a cover plate 3 is removably attached to the upper surface of this outer wall.

Reference numeral 4 denotes a bellows-shaped partition wall for heat exchange, which is located along the outer wall 1, and whose upper and lower ends are fixed to the bottom plate 2 and the cover plate 3, so that an annular partition wall is formed between the outer wall 1 and the partition wall 4. A passage 5 is formed.

Reference numeral 6 denotes a partition plate for further dividing the inside of the partition wall 4 substantially concentrically along the partition wall 4. One end of the partition plate 6 is fixed to the partition wall 4, and the other end of the partition plate is fixed to the partition wall 4. is bent into a substantially circular arc shape to form a substantially annular heat exchange chamber 9 inside the partition wall 4, and furthermore, the tip of the partition plate 6 is separated from substantially the other end of the partition plate. An inlet 10 is provided, and a communication chamber 7 surrounded by a partition plate is formed at the center of the heat exchange chamber 9, and this communication chamber 7 is communicated with an exhaust pipe 8 attached to the center of the cover plate 3.

Also, at a position close to one end of this partition plate 6 and at the bottom plate 2.
A cylindrical body 12 is connected to a hole 11 bored in the hole 11 .

Furthermore, the first and second water pipes 13 and 14 are installed approximately above and below the annular passage 5, respectively, and are located above the annular passage 5 and partition the partition plate 4 and the outer wall 1. An exhaust pipe 16 is provided on one side of the mounting plate 15 connected together, and a feed cylinder 18 is provided on the other side, and a blower 17 is attached to the feed cylinder 18.

In order to use this device, firstly, cooling water is supplied from the first water pipe 13 into the annular passage 5 and circulated within the annular passage 5, and then the first Water is taken out from the second water pipe 14 to the outside, cooled as necessary with a cooling device (not shown), and then returned to the first water pipe 13.
Cooling water is supplied from the annular passage 5 into the annular passage 5.

In this case, the water level in the annular passage 5 is approximately 8 or 9 minutes high, and the second water pipe 14 serves as an overflow.

That is, by preventing the cooling water from flowing into the annular passage 5 at about the 8th or 9th minute, a vacant space 19 is created above the annular passage 5.
remain.

That is, this empty space 5a is divided into two by a mounting plate 15, and a blower cylinder 18 mounted on one side of this mounting plate 15 directs the air generated by the blower 17 to this annular passage 5.
Cooling air is blown into the empty chamber 5a located above the cooling water stored in the chamber 5a to cool the water.

Note that this cooling air can be cooled externally if necessary.

In this way, the bellows-shaped partition wall 4 facing the annular passage 5 is cooled by the cooling air and cooling water, and in this state, the bellows-shaped partition wall 4 is passed from the cylindrical body 12 through the hole 11 of the bottom plate 2. The hot gas accommodated in the heat exchange chamber 9 provided inside the chamber absorbs heat by coming into contact with the bellows-shaped partition wall 4, thereby lowering the temperature of the hot gas.

That is, the hot gas in the heat exchange chamber 9 is gradually cooled and is discharged to the outside from the exhaust pipe 8 through the communication chamber 7 from the inlet 10 located at the other end of the heat exchange chamber.

In this case, if the hot gas has a bad odor, the exhaust pipe 8 can be equipped with a deodorizing device (not shown) to remove the bad odor, thereby making the exhaust gas odorless.

As described above, the present invention forms the outer wall surface of the heat exchange chamber 9 with the bellows-shaped partition wall 4 to make the surface area as wide as possible 1, and furthermore, by making the outer wall surface of the heat exchange chamber 9 into a bellows shape, an uneven surface is formed. The heat exchange efficiency can be increased by disturbing the airflow in the heat exchange chamber so that the air can come into contact with the partition wall 4 as much as possible.

Further, by making the partition wall 4 bellows-shaped, the cooling water flowing in the annular passage 5 and the cooling air flowing in the cavity 5a located above the annular passage become turbulent, and the partition wall 4 Therefore, it has the advantageous feature of being able to absorb heat efficiently.
