Abstract

The present invention relates to a double chimney for preventing water infiltration. Specifically, the double chimney for preventing water infiltration comprises a plurality of pipe bodies stacked on top of each other in a vertical direction. Each of the pipe bodies comprises:: an outer pipe; an inner pipe disposed in the outer pipe and separated from the outer pipe; and an upper and a lower spacer installed between the outer pipe and the inner pipe and separated from each other in the vertical direction to maintain a separation distance between the outer pipe and the inner pipe. An upper end portion of an outer pipe disposed below a different outer pipe is inserted into a lower end portion of the different outer pipe to prevent water infiltration into a chimney through a gap between the outer pipe disposed below the different pipe and the different outer pipe disposed above the outer pipe.

Description

{Double Chimney with Water Permeation Prevention function}

The present invention relates to a double flame, and more particularly, to a double flame preventing water infiltration which can prevent water droplets generated by rainwater, condensation, or the like from penetrating into the inside.

In power plants, incinerators, boilers, and factories, fuels such as coal, oil, and gas are burned to obtain the necessary energy. Chimneys used to discharge the exhaust gases to the outside are usually called flue I call it.

These flats are usually manufactured using stainless steel or steel sheet materials and may be fabricated in the form of a double tube having a heat insulating structure so that the heat of the exhaust gas does not escape to the surroundings when the exhaust gas having a very high temperature passes through the flue.

However, in the conventional double tube type flue as described above, there is no structure for effectively preventing or preventing water droplets or the like generated by external rainwater or condensation phenomenon, and rainwater or water droplets infiltrate into the inside .

FIG. 1 is a perspective view showing a piping body constituting a double flue for preventing water infiltration according to the present invention, and FIG. 2 is a side view of the piping body shown in FIG.

FIGS. 3 and 4 are views showing the inside of the piping body shown in FIG. 1, and FIGS. 5 and 6 are views showing the piping body shown in FIG. 1 stacked.

A double duct (smokestructure) for preventing water infiltration according to the present invention is used for discharging the exhaust gas generated when a fuel such as coal, petroleum or gas is burned in a power plant, an incinerator, a factory, etc., A plurality of pipe bodies 1 are vertically stacked and connected to each other in accordance with the length of the pipe bodies 1.

The piping body 1 of the present invention includes an external piping 10, an internal piping 20 spaced apart from the external piping 10 by a predetermined distance, an external piping 10 and an internal piping 20 A lower spacer 40 disposed at a lower point between the outer pipe 10 and the inner pipe 20 so as to be spaced apart from the upper spacer 30; An auxiliary pipe 50 attached to the inner surface of the inner pipe 20 and a heat insulating material 60 filled between the outer pipe 10 and the inner pipe 20.

The outer pipe 10 has a shape of a long pipe in the vertical direction and has the same diameter from the upper end to the lower certain point, and is formed to be larger in diameter than the other part in the lower end portion. The outer pipe 10 is provided at its lower end with an expanded portion 11 whose diameter is larger than the other portion. The upper portion of the outer pipe 10 is inserted into the expanded portion 11. That is, when the pipe body 1 is vertically connected, the upper end portion of the outer pipe 10 disposed at the lower portion is inserted into the expanded portion 11 of the outer pipe 10 positioned at the upper portion, The upper portion of the outer pipe 10 is not exposed to the outside.

The inner pipe 20 has a shape of a long pipe in the vertical direction and has a diameter smaller than the diameter of the outer pipe 10 so that the inner pipe 20 is installed inside the outer pipe 10, And is installed on the same central axis as the axis.

The inner pipe 20 is inserted into the expanded portion 11 of the outer pipe 10 as described above.

The rainwater flowing downward along the outer surface of the outer pipe 10 disposed at the upper portion is discharged through the lower portion of the outer pipe 10 positioned at the upper portion and the upper portion of the outer pipe 10 positioned at the lower portion Flows downward along the outer surface of the outer pipe (10) located at the bottom without flowing into the pipe body (1). Therefore, water droplets or the like formed on the outer surface of the outer pipe 10 are intrinsically blocked from flowing into the pipe body 1 due to external rainwater or condensation.

The upper spacer 30 is installed on the inner upper side of the piping body 1 and maintains a distance between the outer piping 10 and the inner piping 20. The upper spacer 30 closely contacts the outer surface of the inner piping 20, An extension ring 32 extending from the lower end of the inner ring 31 toward the outer pipe 10 and extending from an end of the extension surface 32 to the upper end of the outer pipe 10, 10 and an outer ring 33 whose height is smaller than that of the inner ring 31.

More specifically, the upper spacer 30 is fixed to the inner pipe 20 by welding or the like, and the outer ring 33 is fixed to the outer pipe 10 by welding or the like. . Even if an external force is applied by the upper spacer 30, the external piping 10 and the internal piping 20 maintain a distance therebetween.

The lower spacer 40 is installed on the lower side of the piping body 1 to maintain a distance between the outer piping 10 and the inner piping 20, An extension ring 42 extending from the upper end of the inner ring 41 to the outer pipe 10 and an outer pipe 42 extending from the end of the extension pipe 42 to the lower end, And an outer ring 43 which is in close contact with the inner surface of the expanded portion 11 of the inner ring 41 and whose height is smaller than the inner ring 41. The other mounting methods and the like are the same as those of the upper spacer 30.

When the piping body 1 according to the present invention is stacked in the vertical direction, the upper end of the outer pipe 10 positioned at the lower portion is in contact with the extending surface 42 of the lower spacer 40, ).

The diameter of the auxiliary pipe 50 is formed to be slightly smaller than the diameter of the inner pipe 20 and the length of the auxiliary pipe 50 is smaller than that of the outer pipe 10 or the inner pipe 20 do. The auxiliary pipe 50 is attached and fixed to the inner bottom surface of the inner pipe 20 by welding or the like and the lower end portion is exposed to the outside through the opened lower end portion of the inner pipe 20.

When the pipe body 1 according to the present invention is stacked in the vertical direction, the auxiliary pipe 50 positioned at the upper part is connected to the inner pipe 50, which is exposed to the outside through the lower end portion of the inner pipe 20, (20). Thus, the fastening force between the piping body 1 located at the upper portion and the piping body 1 located at the lower portion can be further improved.

The heat insulating material 60 is selectively filled in order to prevent the heat of the exhaust gas from being transmitted to the surrounding environment when the temperature of the exhaust gas flowing through the inside of the dual burner according to the present invention is high.

The positional relationship of the respective components when the double flue for preventing water infiltration according to the present invention is stacked in the vertical direction will be briefly described as follows.

The upper end of the outer pipe 10 located at the bottom is brought into contact with the bottom surface of the extended surface 42 of the lower spacer 40 of the pipe body 1 located at the upper portion.

The upper end of the inner ring 31 of the upper spacer 30 is brought into contact with the lower end of the inner ring 41 of the lower spacer 40 or located at a very close position.

The lower end of the inner pipe 20 disposed at the upper portion is in contact with or in close proximity to the upper end of the inner pipe 20 disposed at the lower portion, The lower portion of the inner pipe 50 is inserted into the upper portion of the inner pipe 20 located at the lower portion.
