Description

Dual exhaust pipe

The present invention relates to a dual exhaust structure comprising an outer pipe and an inner pipe, and more particularly to a double exhaust pipe in which a space between an outer pipe and an inner pipe is isolated from the outside.

Generally, in a power plant, an incineration plant, a district heating plant, a chimney that discharges exhaust gas generated when a fuel is used to burn coal, petroleum, or gas in order to obtain necessary energy in a chimney or a factory, is usually called a year. These flats are usually made of stainless steel or steel sheet material and have a double-tube structure with a heat insulating structure so that the heat of the exhaust gas having a very high temperature when passing through the flue does not escape to the outside.

Therefore, the diameter of the double tube tube is used in the order of 150-2000 mm, and the structure thereof is such that an air insulating layer is provided between the outer tube of the inner tube and a gap retainer is attached to the upper and lower portions so as to maintain a gap therebetween.

However, since the space between the outer tube and the inner tube provided by the gap holding bar is opened to the upper side and the lower side, the heat insulating property between the outer tube and the inner tube is lowered, and consequently, condensation easily occurs on the inner side of the inner tube have. In addition, in the conventional flue, when the two inner tubes are connected to each other, the ends of the inner tube are in contact with each other, so that condensation is generated on the inner surface of the inner tube, And eventually flows out of the flue.

The dual exhaust system according to the present invention is a kind of communication for discharging the exhaust gas generated when the fuel is burned, and has a double pipe structure, in which the space between the double pipes is isolated from the outside to improve the heat insulation property, Which is the most important feature in that it is constituted so as to be able to prevent it. That is, the double exhaust year according to the present invention has a cylindrical shape erected with its longitudinal direction facing upward and downward, the upper side inlet 110 formed on the upper side, and the lower side inlet 120 formed on the lower side, (100) having an outer diameter smaller than an inner diameter of the outer tube (100) and inserted into the outer tube (100), the side wall being inclined such that the lower outer diameter is equal to or smaller than the upper inner diameter A first sealing ring 300 formed in a ring shape and covering an upper space of the space between the outer tube 100 and the inner tube 200, And a second sealing ring (400) formed in a ring shape and covering the lower side of the space between the outer tube (100) and the inner tube (200). The first sealing ring 300 includes a first inner tight contact portion 320 which is in close contact with the outer circumferential surface of the inner tube 200 and a first outer tight contact portion 310 which is in close contact with the inner circumferential surface of the outer tube 100 The first inner tight contact part 320 and the first outer tight contact part 310 may be coupled to the inner tube 200 and the outer tube 100 by various welding methods. The second sealing ring 400 includes a second inner tight contact portion 430 which is in close contact with the outer circumferential surface of the inner tube 200 and a second outer tight contact portion 410 which is in close contact with the inner circumferential surface of the outer tube 100 And a sealing ring flange 420 extending outwardly from the lower end of the second inner tight contact portion 430. The second inner tight contact part 430 and the second outer tight contact part 410 may be welded to each other in the same manner as the first inner tight contact part 320 and the first outer tight contact part 310, 200 and the outer tube 100, respectively.

The conventional space retaining plate is formed in a bent strap shape so as to maintain a constant distance between the outer tube 100 and the inner tube 200. However, the first and the second sealing rings 300 and 300, The second sealing ring 400 can maintain the distance between the outer tube 100 and the inner tube 200 constant and also ensure that the space between the outer tube 100 and the inner tube 200 is isolated from the outside Thereby enhancing the heat insulating property between the inner tube 200 and the outer tube 100.

Therefore, by using the double exhaustion according to the present invention, the heat insulation between the outer tube 100 and the inner tube 200 can be improved, so that the occurrence of condensation can be significantly reduced and the combustion gas passing through the inner tube 200 There is an advantage that an accident that the outer tube 100 is excessively heated by the heat of the worker is prevented from being burned.

FIG. 7 is a vertical cross-sectional view showing a structure in which two double evacuation flues are connected. FIG.

Conventionally, the inner tube flange 210 is formed at the upper and lower ends of the inner tube 200 so that the flanges of the inner tubes 200 are arranged to be in contact with each other when the two inner tubes 200 are connected to each other. When the flanges of the tube 200 are arranged to be in contact with each other, when condensation is generated on the inner surface of the inner tube 200 located on the upper side and the tube 200 falls down, the flange of the inner tube 200 located on the upper side and the inner tube 200 may flow out of the inner tube 200 through a gap between mutually abutting flanges. When the condensation formed on the inner surface of the inner tube 200 flows out of the inner tube 200 as described above, the condensation may contact the outer tube 100, and the outer tube 100 may be corroded In addition, there is a disadvantage in that various problems may be caused due to the leakage to the outside of the year and falling on the floor.

In order to solve the above problems, when the two inner pipes 200 are vertically connected, the lower end of the inner pipe 200 located on the upper side is connected to the upper end of the inner pipe 200 located on the lower side, As shown in FIG. When the inner diameter of the inner tube 200 is equal to the diameter of the inner diameter of the inner tube 200, the inner tube 200 can not be inserted into the upper end of the inner tube 200, When the lower end of the inner tube 200 is excessively small, the lower end of the inner tube 200 located on the upper side is located on the upper side of the inner tube 200 located on the lower side. The lower end of the inner tube 200 located on the upper side may be inserted into the upper side of the inner tube 200 located on the lower side in a fitting manner. The lower end of the inner tube 200 located on the upper side may be inserted into the inner tube 200 located on the lower side of the closed ring flange 420 of the second sealing ring 400 located on the upper side, Are positioned so as to be stacked on the inner tube flange 210 located on the lower side.

When the lower end of the inner tube 200 located at the upper side is inserted into the upper end of the inner tube 200 located at the lower side in the fitting manner, if condensation forms on the inner side of the upper tube 200 and falls down The outer pipe 100 is damaged due to condensation because it is only delivered to the inside of the inner pipe 200 located at the lower side and does not flow out to the outside of the inner pipe 200, There is an advantage that no condensation falls on the bottom of the condenser. Since the space between the outer tube 100 and the inner tube 200 is isolated from the outside by the first sealing ring 300 and the second sealing ring 400, Even if a very small amount of condensation is generated on the inner surface of the inner tube 200, the inner surface of the inner tube 200 is left only on the inner surface of the inner tube 200, The condensation is evaporated by the heat of the exhaust gas, so that the condensation does not occur to the outside.

Since the first outer tight contact portion 310 coupled to the inner tube 200 receives a downward weight of the inner tube 200, the first outer tight contact portion 310 slides downward when the coupling strength with the outer tube 100 is somewhat low. have. Accordingly, the first outer tight contact part 310 secures the maximum force of engagement with the outer tube 100, and the outer tube 100 is not slipped down even if the coupling force with the outer tube 100 is somewhat lowered. The upper end of the outer tube 100 and the upper end of the inner tube 110. The upper end of the outer tube 100 and the upper end of the upper end of the outer tube 100 are connected to each other. The first outer tight contact portion 310 coupled to the inner surface of the outer tube 100 is seated on the protruding portion of the upper retractable portion 110 so that the upper retractable portion 110 is not deformed A phenomenon of slipping down will not occur.

The second sealing ring 400 is seated on the inner tube flange 210 of the inner tube 200 located below the sealing ring flange 420 and receives the reaction force of the inner tube flange 210 upward The second sealing ring 400 may be pushed up when the coupling force with the outer tube 100 is lowered. The second sealing ring 400 may be formed in such a manner that the second outer tight contact portion 410 is formed on the inner side of the outer tube 100 and the lower end of the outer tube 100, And it is preferable to mount it so as to cover the entire space between the lower inlet portions 120. The second sealing ring 400 is caught by the lower inlet portion 120 so as to be upwardly moved as far as the lower inlet portion 120 is not deformed even when the upward pressing force is applied. It can not be moved to the other side.

Figs. 8 and 9 are a perspective view and a cross-sectional view of the fastening ring 500 included in the present invention, and Fig. 10 is a vertical cross-sectional view showing a structure in which two double exhaust fins are fastened.

The sealing ring flange 420 and the inner tube flange 210 laminated so as to be in close contact with each other can be integrally joined by the fastening ring 500 that is coupled to surround each outer end. The clamping ring 500 is formed of a pair of semicircular rings 510 having an inserting groove 512 into which the ends of the sealing ring flange 420 and the inner tube flange 210 are inserted, The fastening brackets 520 of the semicircular rings 510 are closely contacted with each other when the pair of semicircular rings 510 are arranged to form a circle, And is fastened by a fastening screw 530.

When the fastening ring 500 is constituted by a pair of semicircular rings 510, the outer diameter of the sealing ring flange 420 and the inner tube flange 210 is larger than the inner diameter of the pair of semicircular rings 510 The sealing ring flange 420 and the inner tube flange 210 can be fixedly coupled to each other by tightening the fastening screws 530 with a slight gap between the pair of fastening brackets 520 facing each other .

In addition, when the sealing ring is exposed to the outside, there is a fear that the sealing ring is broken by an external impact, and the appearance is not very good. Therefore, the double exhausting flue according to the present invention may further include an outer cover 600 which surrounds the space between the two outer tubes 100 arranged up and down, that is, the outer cover 600 mounted to cover the sealing ring. At this time, the outer lid 600 is pulled into the lower draw-in portion 120 of the outer tube 100 positioned at the upper side so that the upper lid 600 can be kept in a fixed state without moving up and down, (110) of the pipe (100).

The double evacuation year according to the present invention is characterized in that the outer tube 100 and the inner tube 200 and the first sealing ring 300 And the second sealing ring 400 may be filled with the heat insulating material 700 as shown in FIG. At this time, the heat insulating material 700 can be applied to any material having a heat insulating property such as glass fiber, styrofoam, resin foam or the like.

In this case, since the inner exhaust pipe 200 is connected to the combustion apparatus, the noise generated in the combustion apparatus is transmitted to the inner pipe 200 and the outer pipe 100 ) And propagates to the outside. However, when the space between the outer tube 100, the inner tube 200, the first sealing ring 300 and the second sealing ring 400 is filled with the heat insulating material 700 as in the double exhaustion according to the present invention, It is possible to reduce the phenomenon that the noise introduced into the tube 200 propagates to the outside through the outer tube 100.

While the present invention has been described in detail with reference to the preferred embodiments thereof, the scope of the present invention is not limited to the specific embodiments but should be construed in accordance with the appended claims. Those skilled in the art will appreciate that many modifications and variations are possible without departing from the scope of the present invention.
