Description

Exhaust pipe for boiler

The present invention relates to an exhaust pipe connected to an exhaust water outlet of a boiler, and is composed of a dual structure and is capable of effectively cooling an exhaust pipe through which high-temperature exhaust gas discharged passes.

In general, gas boilers can be divided into various types according to a control method or a closed state, and in addition, they can be divided into condensing and non-condensing types according to heat sources for heating heating water.

Among them, the condensing method has a sensible heat exchanger that heats the heating water using the heat burned by the burner, and a latent heat exchanger that heats the heating water by using the latent heat of the exhaust gas passing through the sensible heat exchanger, The non-condensing method is equipped only with the heat exchanger of the sensible part.

In the case of a condensing gas boiler, since the temperature of the exhaust gas is lower than that of a general boiler, condensation occurs during the year in which the exhaust gas passes. At this time, the generated condensate is collected into the boiler, and through the condensate discharge hose connected to the sewer to the sewer, etc. Will be discharged.

On the other hand, the conventional double exhaust flue pipe has a form in which several exhaust holes are perforated at the end and is connected to the flue of the boiler to discharge exhaust gas, and an air supply adapter connected to the air supply pipe of the boiler at one end. , In the bottom part of the other end is installed in a form spaced apart so as to have a predetermined interval on the outer circumferential surface of the supply pipe is provided with a plurality of supply air supply is provided in a configuration in which the supply pipe for supplying the external air to the boiler in a double combination It is done.

Then, the outer end of the exhaust pipe is blocked, and the exhaust gas discharged from the flue of the boiler is discharged through the connecting portion and the exhaust holes.

Conventionally, there have been exhaust pipes having a double pipe structure, but the exhaust pipe is heated to a high temperature by the exhaust gas discharged at a high temperature, and in many cases is dangerous.

The present invention is intended to propose an exhaust device capable of easily connecting the exhaust pipes and freely adjusting the length according to the installation environment, and improving the cooling efficiency by using the dual structure of the exhaust pipe and air flow.

The exhaust pipe of the present invention has an outer pipe having a plurality of cooling holes, a first inner pipe located in the outer pipe, and extends outward from one end of the first inner pipe to a size smaller than the first inner pipe. It comprises an inner pipe including a second inner pipe made, the cooling hole is characterized in that a plurality of each formed on the front side and the rear side in the outer pipe.

According to the present invention, there is an advantage that can significantly improve the cooling efficiency of the exhaust pipe.

It should be understood that the existence or addition possibilities of fields or numbers, steps, operations, components, parts or combinations thereof are not excluded in advance.

1 is a perspective view of an exhaust pipe of a boiler according to an embodiment of the present invention, FIG. 4 is a view showing the support of the present invention, and FIG. 5 is a perspective view showing the rear of the exhaust pipe of the present invention.

Referring to the drawings, the exhaust pipe of the present invention is characterized by greatly improving the cooling efficiency of the inner pipe among the dual structures, having a structure capable of continuously fitting/combining a plurality of pieces.

In detail, the exhaust pipe includes an inner pipe 10 through which high-temperature exhaust gas passes, and an outer pipe 200 in which a plurality of cooling holes 210 are formed while surrounding the inner pipe 10.

A plurality of cooling holes 210 are configured on the front side in the outer pipe, and a plurality on the rear side. It is configured to be configured on the front side and the rear side, respectively, excluding the central portion of the outer pipe 200, thereby providing time and space for the introduced air to sufficiently move along the outer circumferential surface of the inner pipe 10.

First to third supports 110, 120, and 130 are formed to maintain a spaced distance between the inner pipe 10 and the outer pipe 200. Each support is arranged at an interval of about 120°.

In addition, the inner pipe 10 has a first inner pipe 11 positioned in the outer pipe 200 and a size smaller than the first inner pipe 11 toward the front outside the outer pipe 200. The second inner pipe 12 is included.

Therefore, by inserting the second inner pipe 12 into the first inner pipe located behind the exhaust pipe, a plurality of exhaust pipes can be continuously connected.

On the other hand, a plurality of cooling holes 210 are formed on the outer circumferential surface of the outer pipe 200 and the outer circumferential surface of the rear pipe, and air flowing into the space between the inner pipe 10 and the outer pipe 200 is provided. It may be discharged through the cooling hole 210 or may be introduced into the outer pipe 200 through the cooling hole 210.

While supporting the space spaced between the inner pipe 10 and the outer pipe 200, the air flow control unit for further improving cooling efficiency will be described later with reference to the drawings.

2 and 3 is a view showing the movement of air and the air flow control unit configured between the inner pipe and the outer pipe in the exhaust pipe of the present invention.

First, as illustrated in FIG. 2, a plurality of air flow control units 141, 142 and 143 formed to protrude to a predetermined height may be configured on the outer circumferential surface of the inner pipe 10.

For example, when three or more air flow adjusting units are configured as shown, they are respectively configured on the front side and the rear side of the exhaust pipe. In detail, the first and second air flow control parts 141 and 142 are disposed close to the cooling hole formed on the front side of the outer pipe 200, and the third air flow control part 143 is the rear side of the outer pipe 200. It is disposed close to the cooling hole formed in the.

In addition, the first to third air flow control parts are formed in a bent shape to have a predetermined curvature between the inner pipe 10 and the outer pipe 200, and the degree of bending and the bending length may be different. However, in the bending direction, each air flow control unit is configured identically.

When configured as described above, cooling of the inner pipe 10 is performed while moving along the outer circumferential surface of the inner pipe 10 while the air introduced into the outer pipe 200 through the cooling hole or the front of the exhaust pipe has directionality. Can help.

In addition, since the air flow adjusting portion is bent to have a predetermined curvature, the length of movement along the outer circumferential surface of the inner pipe 10 increases, so that the cooling efficiency can be further improved. That is, the amount of air rotating the outer circumferential surface of the inner pipe can be greatly increased by the curved air flow control unit rather than the straight air flow control unit.
