Description

Firewood boiler having a detachable wood vinegar collection tank {Firewood boiler having detatchable wood vinegar box}

The present invention relates to a fire wood boiler, and more particularly, to a fire wood boiler in which a pipe and a wood vinegar collection tank are detachably coupled to an outer housing.

In general, a boiler heats water at room temperature using combustion heat generated when an energy source is burned, circulates the heated water along a pipe buried in an indoor floor to heat it, or to use hot water. . As described above, there are electric boilers, gas boilers, oil boilers, oil combined electric boilers having advantages of oil and gas, and the like, depending on the energy source burned to obtain thermal energy.

The gas boiler, the electric boiler, and the electric boiler combined with oil can easily control functions such as ignition, combustion, and fire extinguishing, and thus are widely used in homes and facilities.

However, in recent years, energy prices such as electricity and oil are continuously rising, and in particular, in the case of Korea, energy resources are poor and most of them must be imported from abroad. It is economically a great burden to use boilers.

Accordingly, the development of alternative energy is being actively carried out, and one of them is a wood boiler that can be used with wood or pellets, which are easily obtained at low cost, as a fuel, and has recently been highlighted. Such a firewood boiler is disclosed in Patent Registration No. 10-0426046, Patent Registration No. 10-0679316, and the like.

1 is a schematic diagram schematically showing a cross-sectional configuration of a conventional firewood boiler (10). As shown, the conventional wood-fired boiler 10 has an outer housing 11 in which a combustion chamber in which wood-fired fuel A is combusted is formed, and a communication provided at the upper portion of the outer housing 11 to discharge combustion gas B to the outside. (13) and a flue (15) for guiding the combustion gas in the combustion chamber to the flue (13).

The conventional wood-fired boiler 10 heats water by using high-temperature heat generated when the wood-fired fuel A is burned, and circulates the water into the room through a circulation pump to heat the internal space.

At this time, the heating efficiency may be improved as the time during which the high-temperature combustion gas generated during the combustion of the wood fuel (A) is in contact with the water (W) increases.

The conventional firewood boiler 10 is moved along three passes, in which the combustion gas in the combustion chamber is moved upward by the flue 15, horizontally toward the flue, and vertically moved to the flue 13, as shown in the figure. is emitted as

Since the internal space of the firewood boiler 10 is limited, the exhaust path formed by the flue 15 is limited to two passes or three passes as shown in the figure, so that the time during which the combustion gas can stay in the combustion chamber is limited, thereby improving the combustion efficiency. There were limits to improvement.

On the other hand, when the wood sap from wood, which is the fuel of the wood-fired boiler 10, and moisture in the air meet, wood vinegar is produced. Wood vinegar has strong acidity and is used for pesticides, soil improvement, or food and medicine, but when it meets iron (Fe), it becomes a catalyst for corrosion.

The wood vinegar discharged into the flue 13 through the flue 15 falls vertically to the lower part of the flue 13 and rapidly corrodes the outer housing and combustion chamber of the fire wood boiler 10, which are made of iron. It has the disadvantage of greatly shortening the lifespan.

On the other hand, in the firewood boiler 10, soot and debris, including wood vinegar generated from combustion gas, block the communication pipe 13, so that the communication pipe 13 must be cleaned periodically. If the cleaning of the chimney 13 is neglected, there is a risk that the chimney 13 may be clogged and a fire may occur in the firewood boiler 10 .

However, in the conventional fire wood boiler 10, since the communication pipe 13 is fixed to the upper part of the fire wood boiler 10, the user climbs up to the top of the communication pipe 13 to clean the communication pipe 13 and inserts a long rod, etc. into the inside of the communication pipe 13. It was cumbersome to insert into In addition, there was a problem that the cleaning is more reluctant due to such a hassle.

On the other hand, the firewood boiler 100 of the present invention facilitates the cleaning of the flue 150 and communicates with the wood vinegar collection tank 160 to prevent corrosion of the outer housing 110 and the flue 140 by the wood vinegar solution. ) is provided to be assembled at the rear of the outer housing (110).

As shown in FIG. 3 , the collecting tank connecting pipe 147 of the flue 140 protrudes a certain length to the rear of the outer housing 110 , and the wood vinegar collecting tank 160 is detachable from the protruding collecting tank connecting pipe 147 . possibly combined. And, the communication 150 is detachably coupled to the upper portion of the wood vinegar collection tank (160).

The wood vinegar collection tank 160 detachably connects the communication tank 150 and the collection tank connection pipe 147 so that the combustion gas (B) is moved to the communication tube 150 . The wood vinegar collection tank 160 includes a collection tank body 161 in the form of an enclosure, a communication connector 162 protruding from the upper portion of the collection tank body 161 and a communication tube 150 coupled thereto, and a collection tank body 161. A flue coupling hole 163 that is formed through the side surface of the collection tank connector 147 and is coupled, an opening/closing plate 165 to which the collection tank body 161 is operably coupled to the lower part, and the collector body 161 It is provided on the lower inner side of the upper inner side of the communication connection pipe 162 and includes a communication support plate 167 for fixing the insertion position of the communication pipe 150 .

The collecting tank body 161 is disposed at the rear of the outer housing 110 to connect the flue 140 and the communication 150 . The communication connection pipe 162 is formed to protrude a predetermined length in the vertical direction on the upper part of the collection tank body 161 and supports the communication 150 to be fitted therein. It is formed to have a sufficient length so that the state can be stably maintained.

A communication support plate 167 is coupled to the upper inner wall surface of the collecting tank body 161 on which the communication connector 162 is formed. The communication support plate 167 is formed in the form of a disk in which the wood vinegar discharge hole is formed in the central region. The communication support plate 167 is provided to extend from the upper surface of the wood vinegar collection tank 160 to the lower part of the communication connection pipe 162 by the main body connection pipe 167a.

Accordingly, the lower end of the communication tube 150 inserted through the communication connection pipe 162 is supported in contact with the communication support plate 167 , and the insertion position of the communication tube 150 is limited.

Here, the communication support plate 167 is formed to be inclined downward from the outside toward the inside. Thereby, the wood vinegar (M) dropped through the communication pipe 150 is dropped to the bottom through the wood vinegar discharge hole.

An opening/closing plate 165 is rotatably coupled to a lower portion of the collection tank body 161 . The opening/closing plate 165 is rotatably coupled to the lower portion of the outer housing 110 by a hinge 164 . Although not shown in the drawing, a locking means (not shown) is provided on one side of the hinge 164 to maintain the closed state of the opening and closing plate 165 .

As shown in FIG. 4, the opening and closing plate 165 is connected to the wood vinegar liquid collection tank 160 while using the wood vinegar boiler 100 in a state in which the wood vinegar liquid collection tank 160 is coupled to the collection tank connection pipe 147 and the communication pipe 150. When cleaning is required, the user can clean the chimney 150 without using a ladder or the like to the upper part of the chimney 150 .

That is, when the opening and closing plate 165 is rotated using the hinge 164 , the communication 150 is opened to the outside through the inside of the wood vinegar collection tank 160 . Accordingly, the user can clean the communication tube 150 by inserting a rod or the like into the communication tube 150 from the bottom through the open wood vinegar collection tank 160 .

In addition, the opening/closing plate 165 is generated from the combustion gas (B) moving along the flue 150 and collected so that the wood vinegar (M) falling to the lower part of the flue 150 is not moved to the outer housing 110 side. It also serves as an exhaust.

To this end, the opening/closing plate 165 is inclined downwardly to the right in a direction away from the collector connecting pipe 147 . Thereby, the wood vinegar (M) dropped from the communication pipe 150 is moved along the bottom surface of the inclined opening and closing plate 165.

A wood vinegar discharge hole 166 is formed in the lowest area of the bottom surface of the opening and closing plate 165 . Wood vinegar (M) moved along the slope is discharged to the outside through the wood vinegar discharge hole (166). At the lower portion of the wood vinegar discharge hole 166, a wood vinegar receiver (not shown), not shown in the drawing, may be detachably coupled.

The structure of the wood vinegar collection tank 160 prevents the wood vinegar M from coming into contact with the outer housing 110 and the flue 140 at the source, thereby preventing the shortening of the service life of the wood vinegar boiler 100.

The flue coupling hole 163 is coupled to the collecting tank connector 147 of the flue 140 . The user assembles the wood vinegar collection tank 160 in the flue 140 by inserting the flue coupling hole 163 into the collecting tank connection pipe 147 protruding to the rear of the outer housing 110 when installing the fire wood boiler 100 .

The flue coupling hole 163 is provided with a locking protrusion 163a and a connecting pipe support plate 163b so that the coupling state of the collecting tank connector 147 and the collecting tank body 161 can be stably maintained. The locking protrusion (163a) is formed to protrude inwardly on the upper portion of the flue coupling hole (163), and the connecting pipe support plate (163b) is formed to protrude outwardly at the lower portion of the flue coupling hole (163).

A hook ring (147a) is formed to be bent at the upper end of the end of the collection tank connector (147). The locking ring (147a) is engaged with the locking projection (163a). The user inserts the collection tank body 161 so that the locking protrusion 163a is inserted into the locking ring 147a, and then rotates it downward to insert the collection tank connector 147 into the flue coupling hole 163.

At this time, the connector support plate (163b) supports the lower portion of the collection tank connector 147 inserted into the flue coupling hole (163). As a result, the upper portion of the collection tube connector 147 is fitted to the locking protrusion 163a and the lower portion is supported by the connector support plate 163b so that the position can be stably constrained.

The assembly process and use process of the firewood boiler 100 according to the present invention having such a configuration will be described with reference to FIGS. 2 to 4 .

For the installation of the firewood boiler 100, the user first places the outer housing 110 at a desired place. At this time, the collection pipe connecting pipe 147 of the flue 140 is formed to protrude a predetermined length to the rear of the outer housing 110 .

3, the user inserts the flue coupling hole 163 of the wood vinegar collection tank 160 to the rear end of the protruding collection tank connection pipe 147. At this time, the catch ring 147a of the collector connector 147 is coupled to the collector connector 147 so that it is fitted into the locking protrusion 163a of the upper end of the flue coupling hole 163 .

When the coupling of the wood vinegar collection tank 160 to the collection tank connection pipe 147 is completed in this way, the communication pipe 150 is inserted into the communication connection pipe 162 . The user completes the assembly by inserting the communication tube 150 until the lower end of the communication tube 150 touches the communication support plate 167 .

In order to use the coal-fired boiler 100 , the user opens the door 111 and loads the coal-fired fuel A into the combustion chamber 130 . When the wood fuel (A) is ignited and a blower fan (not shown) is driven, external air flows into the combustion chamber 130 and the wood fuel (A) is burned.

A high-temperature flame and combustion gas are discharged by the combustion of the wood fuel (A). The combustion gas (B) is moved along the multi-path of the flue 140 and is heat-exchanged with the heating water. The combustion gas (B) moves along the combustion chamber coupling pipe 141, the first horizontal pipe 143, the second horizontal pipe 145 and the collection tank coupling pipe 147, and three-dimensionally moves the upper space of the outer housing 110. It moves for a long time and is sufficiently heat-exchanged with heating water.

The moved combustion gas (B) is moved to the wood vinegar collection tank 160 and then discharged to the outside through the communication pipe 150 .

As shown in FIG. 4 , the wood vinegar (M) generated while the combustion gas (B) is moved along the communication pipe 150 falls downward and comes into contact with the communication support plate 167 . Then, after gathering in the center by the inclination angle of the communication support plate (167), it falls to the lower part, and falls to the opening and closing plate (165).

Since the opening and closing plate 165 is formed as an inclined surface having an inclination angle, the wood vinegar M is discharged to the wood vinegar discharge hole 166 after moving along the opening and closing plate 165 .

In this process, the wood vinegar (M) is collected in the middle region of the communication support plate 167 and then falls, and is discharged along the opening and closing plate 165 to the wood vinegar discharge hole 166, so it is blocked from moving toward the flue 140 and the flue ( 140) or the external housing 110 can solve the conventional problem that was corroded in contact with the wood vinegar (M).

On the other hand, if the firewood boiler 100 is used for a certain period of time, for example, for a week, the user opens the opening/closing plate 165 . Then, through the open collection tank body 161, a tool such as a rod can be inserted from the lower side toward the upper side toward the communication tube 150 to clean the communication tube 150 .

As described above, the firewood boiler according to the present invention is provided so that the external housing, the wood vinegar collection tank and the communication can be easily assembled, so that it can be easily separated during transport or cleaning.

In particular, the opening and closing plate of the lower part of the wood vinegar collection tank is rotated and provided to open and close, so that the user can provide the convenience of cleaning the communication by inserting a cleaning tool from the lower part of the wood vinegar collection tank into the communication tube.

In addition, in the firewood boiler of the present invention, the combustion gas is moved along a multi-path of 5 passes including the flue and the flue. As a result, the movement path of the combustion gas becomes longer and the contact time with the heating water becomes longer, so that the thermal efficiency and heating efficiency of the firewood boiler can be improved.

In addition, in the firewood boiler according to the present invention, the communication is arranged to be spaced apart from the rear of the outer housing, and a wood vinegar collecting tank is provided at the lower part of the communication, so that the wood vinegar separated from the communication is fundamentally blocked from contacting the outer housing and the flue.

Thereby, it is possible to solve the problem that the life of the fire wood boiler is shortened due to corrosion by the wood vinegar.
