  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, exemplary embodiments of the invention will be described in detail with reference to the accompanying drawings.

  As shown in FIGS. 1 to 3, the multi-stage boiler heat exchange apparatus of the present invention includes a combustion furnace 10 and at least one boiler mechanism 20.

The combustion furnace 10 is a furnace body that is arranged in the vertical direction and generates heat energy by burning fuel. A furnace seat 11 is provided at the bottom of the furnace 10, and a hot air guide tube 12 is attached to the top of the furnace. It has a transport unit 13 for storing and transporting, and the transport unit 13 includes a storage tank 14 and a transport bucket 15. The storage tank 14 is disposed on one side of the combustion furnace 10, and serves as rice, wheat, coffee After storing grains such as beans and shelling out the grains, the remaining industrial waste can be reused as biomass fuel, and the transport bucket 15 is connected to the combustion furnace 10 so as to be connected to the combustion furnace 10. Attached to the lower side, the biomass fuel is conveyed and sent to the combustion furnace 10. In addition, since the assembly structure of the storage tank 14, the conveyance bucket 15, and the combustion furnace 10 is a well-known technique, the description is abbreviate | omitted.
Further, when the biomass fuel is burned using the combustion furnace 10, the burned ash or incompletely burned biomass fuel accumulates in the furnace seat 11 of the combustion furnace 10, and ash collection is performed in the vicinity of the furnace seat 11 of the combustion furnace 10. A tank 16 is disposed, and the ash burned in the combustion furnace 10 is stored in the ash collection tank 16.

  The boiler mechanism 20 is installed so as to be connected to the combustion furnace 10, and includes a temperature adjuster 21 and a boiler body 22 connected to the temperature adjuster 21, and the temperature adjuster 21 is connected to the hot air guide tube 12. It is installed on one side of the combustion furnace 10 so as to adjust the temperature of the introduced thermal energy and prevent it from entering the boiler main body 22 at a high temperature, and according to this, the boiler main body due to the high temperature from the thermal energy Since the multistage boiler heat exchanger according to the present invention has the temperature regulator 21, the service life of the boiler body 22 can be extended and the boiler body 22 can be made fireproof. Since it is not necessary to manufacture from this material, cost can be saved and thermal energy can be used efficiently.

  The boiler body 22 is installed in the vertical direction, and a heat transfer tube 221 having one end communicating with the temperature regulator 21 is attached to the outer surface near the bottom thereof, and the other end of the heat transfer tube 221 is connected to the boiler body 22. The heat energy generated from the combustion furnace 10 is transmitted from the temperature regulator 21 to the boiler body 22. Further, a heat exchange tube for storing a heat exchange medium is provided inside the boiler body 22, and the heat exchange medium is transmitted to the boiler body 22 and exchanges heat with heat energy. In addition, the heat exchange tube is a coil tube piped in the vertical direction.

As shown in FIG. 4, the multistage boiler heat exchanging device of the present invention is installed in the horizontal direction so that the heat transfer tube 221 connects the bottom of the temperature regulator 21 and the bottom of the boiler body 22, and the boiler. Since the main body 22 is arranged in the vertical direction, when the heat energy from the temperature regulator 21 is transmitted to the boiler main body 22 through the heat transfer tube 221, the direction in which the heat energy is transmitted changes (in accordance with FIG. The ash is separated from the direction, that is, the ash is separated by the direction change), so that the generated thermal energy and the burned ash can be separated to discharge the ash.
Further, since the boiler body 22 is arranged in the vertical direction, the flow rate of the thermal energy transmitted from the temperature regulator 21 to the boiler body 22 is reduced, so that it cannot move with the ash inside the boiler body 22. Ash can be separated from thermal energy (ash can be separated by speed change). Therefore, according to this method, the burned ash is not clogged in the boiler body 22, so that it is not necessary to install a dust collecting device and the cost can be saved. The boiler body 22 is preferably a steam boiler or a hot water boiler.

  As shown in FIGS. 1 and 3, the at least one boiler body 22 further includes a chimney unit 23, and the chimney unit 23 is installed so as to be connected to the upper part of the boiler body 22, and the dust collector 231. The dust collector 231 is disposed so as to be connected to the boiler body 22 and guides and discharges the heat energy and smoke from the boiler body 22 to thereby discharge the boiler body 22. The air discharger 232 is disposed so as to be connected to the dust collector 231 and discharges heat energy and smoke guided to the dust collector 231 to the outside. At this time, cold air is introduced while discharging hot air, so that the safety in use of the multistage boiler heat exchanger of the present invention is improved.

When using the multistage boiler heat exchange apparatus of the present invention, as shown in FIGS. 1 and 4, the biomass fuel stored in the storage tank 14 is transferred to the combustion furnace 10 by the transfer bucket 15 of the transfer unit 13. The biomass fuel is burned in the combustion furnace 10 to generate thermal energy, and the thermal energy enters the temperature regulator 21 through the hot air guide tube 12, and the ash remaining in the furnace seat 11 is removed from the ash collection tank 16. To collect. And by adjusting the temperature of the thermal energy by the temperature regulator 21, the thermal energy is prevented from being transmitted to the boiler body 22 at a high temperature, and the boiler body 22 is prevented from being damaged due to the high temperature.
Thus, since the multistage boiler heat exchange device of the present invention can prevent the boiler body 22 from being damaged due to high temperature if the temperature regulator 21 is installed, the service life of the boiler body 22 can be extended, and the boiler body Since it is not necessary to manufacture 22 from a refractory material, costs can be saved and the efficiency of heat exchange can be improved.

As shown in FIG. 5, the multi-stage boiler heat exchanger of the present invention is attached so that the heat transfer tube 221 is connected to the bottom of the boiler body 22 and the boiler body 22 is arranged in the vertical direction. When the heat energy generated from the temperature regulator 21 passes through the heat transfer tube 221 and is transmitted to the boiler body 22, the direction in which the heat energy is transmitted changes, and the generated heat energy and the burned ash are separated. It can be discharged (ash is separated by changing direction).
In addition, since the boiler body 22 is arranged in the vertical direction, the flow rate of the heat energy transmitted from the temperature regulator 21 to the boiler body 22 is reduced and cannot move with the ash inside the boiler body 22. The ash separates from the thermal energy (the ash is separated by the speed change). Therefore, since the burned ash is not clogged in the boiler main body 22, it is not necessary to install a dust collector, so that the cost can be suppressed.
