Description

[Detailed explanation of the idea] The present invention relates to a dust removal device.

Conventionally, dust emitted from dust-generating facilities was removed using dust collectors, but as it was impossible to remove it completely, a portion of the emitted dust accumulated in the horizontal flue leading to the chimney, and was mutually removed. The problem was that the soot and dust, which had become coarse due to the adhesion of the smoke, would be scattered by the rapid increase in gas flow velocity, be discharged from the chimney, and fall into the vicinity.

The present invention aims to eliminate the above-mentioned drawbacks by simple means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of the implementation of the present invention will be explained below based on the drawings.

Reference numeral 1 denotes a chimney, which has an inner cylinder 3 in the axial direction at the center near the exhaust gas inlet 2, and the inner cylinder 3 has a partition wall so that the exhaust gas inlet 2 communicates with the upper part of the chimney 1 through the inner cylinder 3. A spiral guide plate 6 is fixed to the partition wall 4 between the inner cylinder 3 and the chimney inner surface 5 facing the inflow port 2.

The bottom of the chimney 1 below the spiral guide plate 6 and the lower end opening of the inner cylinder 3 is configured as a dust collection space 7 .

8 is a manhole, 9 is a horizontal flue, and 10 is a soot.

In the above configuration, the soot and dust 10 deposited at the bottom of the horizontal flue 9 and scattered due to the increase in gas flow velocity is entrained by the exhaust gas and flowed in the circumferential direction along the spiral guide plate 6, increasing the speed. At the lower part of the inner periphery 3, due to the separation speed of the soot and dust 10 with gravity, it falls into the dust collection space and is collected, and is taken out from the manhole 8 as appropriate.

The exhaust gas from which the soot and dust 10 has been separated is discharged to the upper part of the chimney 1 through the opening at the lower end of the inner cylinder 3.

As described above, according to the present invention, the gas flow velocity is increased using a spiral guide plate, and the soot and dust contained in the exhaust gas is removed using the centrifugal force of the spiral guide plate and the ventilation force of the chimney, and only requires the addition of a simple device. This makes it possible to easily remove soot and dust that was not completely removed by the dust collector before it is discharged from the chimney, and its industrial value is extremely large.
