As shown in FIGS. 1 to 4, the warm air generator includes a combustion unit 100 including a burner 110, a fuel supply unit 200 for supplying particulate fuel to the combustion unit 100, It is provided in the combustion unit 100 and comprises a warm air generating unit 300 for supplying the warm air with a temperature rise by the combustion unit 100 to the destination.

Looking at this in more detail as follows.

First, the fuel used in the present invention can be applied to anything that has a particle form. That is, but may be made of chaff, sawdust, pellets, etc., preferably made of chaff. Chaff is obtained after threshing rice, and does not have to harm nature such as wood, and does not generate harmful gas or waste such as oil or coal, and is economical because it is cheaper than anything else. Therefore, in the present embodiment, the chaff is used as a fuel, and the fuel is carbonized (burned) and will be described on the basis of making charcoal.

Combustion unit 100 is formed in a cylindrical shape of a predetermined length is installed in the vertical direction. The reason for being formed in a cylindrical shape having a predetermined length is to facilitate heat exchange with outside air in the middle part when heat generated by combustion of fuel on the lower side is discharged to the upper side. That is, the outside air is in contact with the combustion unit 100 for a long time (heat exchange) to obtain a high temperature warm air. And a conical discharge portion is installed on the upper portion of the combustion unit 100, the discharge pipe 120 is connected to this discharge portion is installed. The combustion member 109 of the conical structure which has fallen down is installed in the lower part, and the burner 110 is installed in this combustion member 109 inside. And, on the outer circumferential surface of the combustion member 109, a pipe 132 having one end connected to the external air supply fan 130 for combustion / discharge is arranged in a circular shape, and each branch pipe branched from the inner diameter of the pipe 132 is formed. 134 are installed to communicate with the combustion member 109 to forcibly supply external air from the lower portion of the combustion unit 100 to the upper side. At this time, each branch pipe 134 is installed to be inclined in the advancing direction of the outside air so that outside air supplied by the outside air supply fan 130 for combustion / discharge causes spiral vortex to the upper side on the inner lower side of the combustion member 109. Will be. This spiral vortex is intended to facilitate the ignition and to facilitate the discharge to the top by allowing the particulate fuel supplied by the fuel supply unit 200 to be scattered.

Such a combustion unit 100 does not require a ash collecting or ash discharging device for discharging the burned fuel. This is because the outside air forcedly supplied by the combustion / exhaust air supply fan 130 forcibly discharges the fuel in combustion to the discharge pipe 120.

In addition, the fuel such as chaff ignited in the lower portion of the combustion unit 100 is moved upward while being dispersed while moving upward by the spiral vortex formed by the outside air supplied by the combustion / exhaust air supply fan 130 for combustion.

In order to form a zigzag flow path from the upper side to the lower side in the temperature rise space S in which the exhaust pipes 340 are installed. It consists of a raised area (S) a plurality of passage-forming plate (380) provided alternately on. At this time, the lower end portion of the exhaust pipe 340 (the diaphragm of the lower region side) is expanded like a fallopian tube so that the fuel in the form of particles such as carbonized chaff is easily and quickly moved to the upper region 101 side without interfering with the end thereof. It is desirable to.

The warm air generating unit 300 is a temperature rising space after the heat is introduced into the exhaust gas discharged while passing through the outside of the upper region 101 by the outside air induction unit 310 by the axial fan 320 is preheated While gradually passing (S) in a zigzag from the upper side to the lower side is gradually discharged to the warm air outlet 350. And, since the combustion unit 100 is formed long in the longitudinal direction and installed in the vertical direction, the temperature rise space (S) therein is formed long in the vertical direction, so that the outside air in each of the exhaust pipes (S) in the temperature rise space (S) 340 can be sufficiently heat exchanged with the temperature rises. In addition, the first outdoor air introduced through the upper region 101 (exhaust side) of the combustion unit 100 is preheated by the exhaust gas, and then warms up in earnest while passing through the temperature increase space S. Finally, the combustion unit The lower part of the 100, that is, the temperature is raised in a region close to the lower region 102 where the chaff is ignited and then transferred to the hot air supply pipe 360.

On the other hand, the connecting pipe 710 connecting the cyclone apparatus 500 and the char storage hopper 700 to the outside air connection pipe 710 so that the char discharged from the cyclone apparatus 500 is transferred to the char storage hopper 700. A supply external air supply fan 720 for supplying is installed, and the outside air forced by the external air supply fan 720 for transportation is not introduced into the cyclone device 500 at the lower portion of the cyclone apparatus 500, and The second rotary valve device 530 for continuously discharging the carbonized fuel collected by a predetermined amount is installed.

On the other hand, the exhaust fan 124 for forcibly discharging the exhaust gas is provided at the end of the exhaust pipe 122 provided in the cyclone device 500, the exhaust communication 126 is connected to the exhaust fan 124. At this time, the exhaust communication 126 is composed of a main communication installed vertically, and a secondary communication communicating in the horizontal direction at the middle of the main communication. This is for dust and the like contained in the exhaust gas to be collected by gravity to fall below the main cylinder. In addition, the exhaust communication 126 is provided with a cooling device 800 for spraying the cooling water in the form of fine particles. This cooling device 800 has the same configuration as described above. That is, at least one second coolant injection nozzle 850 is installed in the exhaust communication 126, and the coolant supply pump 840 supplies the coolant to the second coolant injection nozzle 850. At this time, the cooling water supply pump 840 is configured to simultaneously supply the cooling water to the first cooling water injection nozzle 820 installed in the connection pipe 710 and the second cooling water injection nozzle 850 for supplying the cooling water to the exhaust communication 126. It may be configured separately to supply the cooling water to the first and second cooling water injection nozzles (820, 850). The fine water particles injected from the second coolant injection nozzle 850 have a function of aggregating and removing contaminants contained in the exhaust gas.

Referring to the operation of the present invention configured as described in detail as follows.

When the burner 110 installed at the lower part of the combustion unit 100 is operated while the burner 110 for ignition is ignited, the outside air is forcedly supplied to form a spiral vortex from the lower part of the combustion unit 100 to the upper side. Done. The outside air functions to transfer the chaff supplied to the discharge pipe 120 while supplying oxygen required for combustion of the fuel.

In this state, when the external air supply fan 240 for fuel supply is operated, external air is supplied to the supply pipe 220, and at the same time, the first rotary valve device 232 operates to form a particle state stored in the fuel storage hopper 231. Fuel (rice husk) is supplied to the supply pipe (220).

Therefore, the chaff is helically discharged along the tangential direction of the combustion unit 100 through the supply pipe 220 by forced external air, and discharged by spiral vortex forcedly supplied from the lower part of the combustion unit 100 at the same time. It is dispersed, and at the same time combustion occurs. At this time, since the chaff in the form of particles is supplied while being dispersed in the upper side of the lower region 102, combustion is made in an instant.

On the other hand, the chaff discharged to the lower region 102 is dispersed in the upper region 101 through the respective exhaust pipes 340 by the external air forced by the external air supply fan 130 for combustion / discharge at the same time as the combustion proceeds The exhaust pipe 340 is heated while moving to).

Subsequently, the fuel which is not completely burned while being moved to the upper region 101, that is, the combustion proceeds, is introduced into the cyclone apparatus 500 having a temperature lower than that of the combustion unit 100 through the discharge pipe 120. Therefore, since the heat required for the combustion moved to the cyclone apparatus 500 through the discharge pipe 120 is deprived, the combustion does not proceed anymore. Therefore, it is in a carbonized state.

In this process, the fuel introduced into the cyclone apparatus 500 becomes charcoal, and the charcoal is discharged in the tangential direction of the body 520 and descends spirally by centrifugal force. In this process, the rice husk is collected to the lower portion of the body 520, the exhaust gas is discharged to the exhaust pipe (122).

The exhaust fan 124 is operated to quickly exhaust the exhaust gas inside the body 520 and to the outside. In this process, a strong vortex is successfully formed inside the body 520.

The chaff charcoal collected in the cyclone apparatus 500 is transferred to the char storage hopper 700 through the connection pipe 710 in this process. At this time, the chaff charcoal collected by the cyclone apparatus 500 and discharged by the second rotary valve device 530 by forced air supplied by the external air supply fan 720 for transporting is charcoal through the connection pipe 710. It is transferred to the storage hopper 700. In this way, the transfer of charcoal can be made quickly and easily by the external air supply fan 720 for transfer.

Then, the chaff char which is transferred to the char storage hopper 700 through the connection pipe 710 is stored in the char storage hopper 700 in a state cooled by the cooling device (800). That is, the cooling water supplied by the cooling water supply pump 840 is sprayed by the first cooling water injection nozzle 820 to extinguish or cool the remaining embers.

On the other hand, the exhaust gas separated from the rice husk char while passing through the cyclone apparatus 500 is discharged to the exhaust communication 126 through the exhaust pipe (122). At this time, the exhaust gas is forcibly discharged by the exhaust fan 124, and various harmful substances contained in the exhaust gas forcibly discharged are minutely injected through the second coolant injection nozzle 850 installed in the exhaust communication 126. It is cooled by the coolant and removed at the same time. That is, since fine cooling water is injected into the exhaust gas, dust and various harmful substances contained in the exhaust gas are aggregated into the fine cooling water and collected and removed to the lower portion of the main communication.

Carbonized fuel is collected in the cyclone apparatus 500 in a process of moving from the combustion unit 100 to the cyclone apparatus 500 by the above-described process, so that a separate apparatus for obtaining charcoal is unnecessary. Charcoal can be used as a soil improver to prevent soil from being contaminated and acidified by excessive fertilizers or pesticides, and to improve intellect.

On the other hand, when the combustion unit 100 is heated while the fuel such as chaff is supplied to the combustion unit 100 and burned, it is forcedly supplied to the axial fan 320 installed in the external air induction unit 310 surrounding the upper region 101. The outside air is gradually heated up while passing through the temperature increase space S formed by the upper and lower diaphragms 330 in a zigzag form.

That is, the outside air preheated while passing through the outside air induction part 310 is contacted with the plurality of exhaust pipes 340 while passing through a zigzag-shaped flow path formed by the plurality of diaphragms 380 and heated up to the warm air discharge part 350. It is discharged to the hot air place.

At this time, since the combustion unit 100 is formed to have a predetermined length to have a temperature rise space S having a zigzag flow path, the outside air may be sufficiently heated. In particular, by having a structure as described above can be maximized thermal efficiency.

On the other hand, although not shown in the drawing, by installing a temperature sensor in the hot air supply pipe 360 can be controlled to generate a warm air of the temperature required in the hot air using place.

As described above, the warm air generating device according to the present invention can produce chaff charcoal while simultaneously generating hot air using chaff which is an eco-friendly fuel, thereby maximizing energy efficiency and usefully utilizing waste resources.
