BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry incinerator for a golf course, which can burn all combustible wastes including turf grass discarded from a golf course.

[0002]

2. Description of the Related Art At a golf course, greens (vented grass, korai grass), mowed grass on fairways, dead grass from the surrounding forests, thinned wood, shrub litter, general garbage, kitchen waste from clubhouse restaurants, etc. , Various things are being discarded. Among these, relatively burnable hay and thinned wood, which do not contain much water, are incinerated by a general incinerator provided at a golf course. However, bent grass, which has just been cut, contains a large amount of water (85 to 90%), so it is difficult to incinerate it in an ordinary incinerator.

[0003] For example, even if the turf grass containing a large amount of water is put into the burning incinerator as it is, only the surface portion of the lump burns and the inner portion remains unburned. Also, when the amount of turfgrass is large, the content of water may cause the flame of the incinerator to be extinguished. Therefore, it is possible to combust by mixing waste oil, tires, etc. as an auxiliary combustion material, but it is very troublesome and not suitable for practical use.

[0004] Although there is a means to dispose such turfgrass grass and kitchen waste that cannot be incinerated in the ground, since the turfgrass emits an offensive odor and contains a large amount of pesticide, it remains in the ground. If it is buried in, the agricultural chemicals contained in it will be diffused by rainwater etc. and cause pollution.

Therefore, an example of a dry incinerator for a golf course for incinerating turfgrass that cannot be incinerated is shown below with reference to FIGS. 10 (a) and 10 (b). In the figure, (1) is a hopper, (2) is a screw conveyor, (3) is a drying furnace, and (4) is an incinerator. As shown in FIG. 10 (b), the hopper part (1) is a horizontally long gutter-shaped storage container having an inverted triangular shape in vertical cross section, the opening width of which gradually narrows downward. The turfgrass (Xa) is directly supplied by and stored temporarily near the bottom. The screw conveyor (2) is
As shown in FIGS. 10 (a) and 10 (b), the hopper is horizontally arranged on the bottom (1b) of the hopper (1), and is rotationally driven by a drive motor (5) below the hopper via a belt (6). To be done. Then, the cut grass (Xa) supplied to the hopper unit (1) and accumulated near the bottom is sequentially conveyed to the take-out port (1a) of the hopper unit (1).

In the drying oven (3), a screw drum (8) is horizontally rotatably disposed inside the drying chamber (7), and a heat insulating material is laid on the inner wall of the drying chamber (7). Alternatively, the drying chamber (7) itself is made of a heat insulating material. The screw drum (8) is provided with fins (9) spirally extending forward on the inner peripheral surface, and is appropriately arranged so that a scraping piece (not shown) for raw grass crosses the fins (9). Then, it is rotationally driven by a drive motor (10) provided below via a belt (11). Further, the screw drum (8) is connected to the outlet (1a) of the hopper (1) which penetrates the sealing cover (12) attached to the rear end of the drying chamber (7), and is attached to the front end of the sealing. An outlet (14) for the dried grass (Xb) is formed in the lower part of the cover (13), and a transport fan (15) connected to the outlet (14) and a dried grass supply port (16) of the incinerator (4) described later are provided. ) Is connected with a carrier pipe (17). In addition, the exhaust heat gas (Ga) discharged from the chimney (19) of the incinerator (4) enters and leaves the space (18) formed between the screw drum (8) and the drying chamber (7). A gas inlet (20) and a gas outlet (21) are formed.

The incinerator (4) has a primary combustion chamber (22) for burning grass grass and a secondary combustion chamber for gas combustion which is arranged continuously above the primary combustion chamber (22). And a combustion chamber (23). The primary combustion chamber (22) has a double adiabatic wall structure, the auxiliary combustion burner (24) and the combustion fan (25) are arranged on the lower side surface, and the exhaust heat gas (Gb) generated during incineration is It is sent to the secondary combustion chamber (23) and incinerated, and an ash outlet (26) is formed at the bottom of the wall surface.

The exhaust heat gas (Gb) containing smoke and the like generated by the combustion is completely combusted by the afterburner (29) in the secondary combustion chamber (23) to remove the exhaust heat gas (Ga ). Then, a part of the exhaust heat gas (Ga) is supplied from the chimney (19) through the reflux pipe (31) to the space (18) of the drying furnace (3), and as described above, the screw drum (8). After being continuously heated, it is returned to the chimney (19) from the discharge pipe (32) and sent to the dust collector (30).

[0013]

The problem to be solved is to convey the turf grass (Xa) in the hopper section (1) by the screw conveyor (2), for example, in rainy weather, when the hopper section (1) is When rainwater collects on the bottom part (1b) of the grass and reaches a saturated state where the moisture content of the turfgrass (Xa) reaches 100%, water is sent by the screw conveyor (2) and enters the drying furnace (3),
The excess of water reduces the drying efficiency, and the heavy grass grass (Xa) containing rainwater is compacted by the rotation of the screw conveyor (8), and the inside of the feed teeth of the screw conveyor (8) is compacted. The point is that the screw conveyor (8) becomes rod-shaped when it is packed to the full depth without any gaps, and the screw conveyor (8) runs idle and cannot be conveyed.

In this case, instead of the screw conveyor (8), as shown by the chain line in FIG. 10 (b), a double screw conveyor in which a fixing bar (34a) for breaking up the pile of the turf grass (Xa) is added. (34) It is possible to prevent the grass clippings (Xa) from clogging the feed dog to the full depth without any gap. However, a bridge of the turfgrass grass (Xa) is formed on the double screw (34), which makes it impossible to convey the turf in the same manner, which further increases the cost.
In addition, if solid foreign matter such as pebbles or wood chips with a diameter larger than a predetermined size enters the hopper (1) and further into the drying oven (3), it will be caught by the transportation fan (15) and the blade may be damaged in some cases. Occurs.

An object of the present invention is to provide a dry incinerator for a golf course which conveys the whole grass grass (Xa) to the end so that water is not accumulated in the hopper and no bridge is formed in the hopper. It is to be.

When the level sensor (101) confirms that a sufficient amount of the cut grass (Xa) is stored in the hopper, the circulation fan (69) in the lower duct chamber (68) is activated, and If the temperature inside the screw drum (52) of the drying chamber (51) is 300 ° C or less by the temperature controllers (102) and (103) for the hot burner and damper, the damper control (104) will operate and Three
The heating burners (73) ignite in the direction in which the dampers (Db) (Dc) close and the direction in which the first damper (Da) opens. Then, the dry hot air (H) heated by the heating burner (73) is supplied from the burner combustion chamber (70) into the drying chamber (51) through the gas inlet (65), and the space inside the drying chamber (51). At (63), the partition plate (56) meanders to uniformly heat the space (63).

When the temperature inside the screw drum (52) of the drying chamber (51) reaches 300 ° C. or higher, the belt conveyor (feeding feeder) (41) starts to move, and the grass turf (Xa) is transferred to the belt conveyor (41). Are sequentially stored in the bucket portion opening surface (46a) located below the bucket portion (46a) and conveyed from the bottom portion (40a) to the upper opening. At this time, as the grass grass (Xa) is sequentially scraped off from the side wall of the bottom (40a) and stored in the bucket part (46) ..., the grass grass (Xa) drops into the bottom (40a) and is sequentially clogged. Therefore, even if a bridge is formed in the hopper part (40), the end part of the bridge is immediately scraped off by the bucket part (46) and the bridge collapses.

Further, even if solid foreign matter (Q) such as pebbles or wood chips enters the bucket portion (46) ..., the cover body (47) is in the middle of transportation.
If the bucket height (Db) is greater than that of the bucket body (47), the end surface of the cover body (47) collides. Then,
Since the belt conveyor (41) is inclined upward at a steep angle, it is easily ejected from the bucket portion (46) to the hopper portion side. Therefore, it is possible to prevent troubles such as the transportation fan (58) being damaged by the solid foreign matter (Q).
Since the solid foreign matter (Q) ejected into the hopper (40) collects on the bottom (40a), the inspection port (50) is opened and removed as appropriate. In addition, even if the bucket height (Db) is smaller than the bucket height, there is no particular problem even if it is mixed. Also, the hopper (40)
Rainwater and the like collected in the bottom portion (40a) of the tank is discharged from the drain hole (W) and does not enter the next drying furnace (42). At the same time, the turf grass (Xa) at the bottom (40a) is picked up sequentially by the ascending bucket part (46) ... and does not spill outside.

Next, the turf grass (Xa) conveyed to the upper opening by the belt conveyor (41) in the hopper (40) passes through the drop chute (48) and is screw drum (rotary drum).
It is dropped and supplied into (52). Then, since the screw drum (52) is sufficiently heated, the fin (53)
And radiant heat is released from the scraping piece for raw grass, and the raw grass (Xa) is dried. At the same time, the cut grass (Xa) is lifted diagonally upward along the fins (53) by the scraping piece for raw grass and drops downward, and is gradually conveyed in front of the fins (53). In this way, the turfgrass (Xa) is sufficiently loosened from the dense state and broken into pieces, and further, it is stirred while being sufficiently heated by the radiant heat, so that the moisture content is 60% or less in a very short time. . In this way, the grass turf (Xa) becomes dry turf with a water content of 60% or less and the outlet (5
9) Taken out from the carrier pipe (6) by the transportation fan (60).
It is supplied to the incinerator (43) through the dry grass supply port (61) through 2). When the inside of the hopper is empty, the belt conveyor (41) is stopped, and the circulation fan (69) and the screw drum (52) are stopped by the drying timer (105).

On the other hand, in the case of the incinerator automatic circuit, first, the afterburner fan (112), the ignition burner fan (113) and the combustion fan (81) are sequentially operated, and then the timer (11
By the operation of 4), the air nozzle (82) ...
It operates as shown in the flow sheet. Further, the pre-purge timer (115) is activated, and the temperature controller (116) in the second combustion chamber (77) controls the ignition of the afterburner (89) so as to reach a predetermined temperature. Next, if the temperature is a predetermined temperature, for example, 300 ° C or lower, by the temperature controller (117) of the primary combustion chamber (76),
Ignite the ignition burner (78). When ignited, the ignition burner (78) is burned while supplying dry grass, and the dry grass that is being supplied by the fire of the burner is burned to fall on the upper surface of the combustible material accumulated in the combustion chamber. Then, the dried grass is easily incinerated together with the incinerable waste in the primary combustion chamber (76) so that the combustibles are sprinkled with the sparks. The ignition burner (78) is set to 3 by the temperature controller (117) after ignition.
Extinguish the fire if it is over 00 ° C.

Here, as the combustion level sequentially decreases from the upper stage, the blow dampers of the four stages of the air nozzles (82) ... Are controlled so that the uppermost air nozzles (82) ... Combustion is further promoted by performing optimal air supply while controlling the injection. For example, as shown in the flow sheet of FIG. 9, when opening the uppermost stage, the other three stages are closed, and when opening the next stage, the other three stages are closed. When the third stage is opened, the other three stages are closed, and when the bottom stage is opened in the final stage, the third stage is opened and the other two stages above are closed. Then, when the combustion level drops and the temperature in the combustion chamber drops, the lower burner (79) automatically ignites and combusts the unburned combustibles to the end. When the unburned residue remains, the lower burner (79) is manually ignited. After burning, the automatic stop push button (118) is pressed to stop the drying furnace and the incinerator.

Since the dry grass is transported by air by the transport fan (60) and the transport pipe (62), the odor and steam in the drying furnace are also incinerated together with the dry grass through the transport pipe (62). It is transferred into the primary combustion chamber (76) of the furnace (43). When the dried grass is incinerated, the odor and steam in the drying oven are also incinerated at the same time. Therefore, the odor is thermally decomposed and removed in the primary combustion chamber (76), and the pesticide contained in the odor can be incinerated and removed at the same time. Also, the high-temperature odor and steam can be used to supply combustion air to improve combustion efficiency, and since steam is moist hot air, it can be supplied into the primary combustion chamber (76). An abnormal combustion temperature rise in the primary combustion chamber (76) can be suppressed to maintain an optimum combustion state at all times. Furthermore, the odor and steam in the drying oven are the first
Since the combustion process is performed in the secondary combustion chamber (76), the combustion of the heating source of the secondary combustion chamber (77) is reduced, and the fuel consumption can be reduced.

The exhaust heat gas (Gb) containing smoke, soot and the like generated by the combustion is tangentially introduced into the secondary combustion chamber (77) and swirls in the cylindrical chamber to come into contact with air. While increasing the area, it is completely burned by the afterburner (89) and becomes exhaust heat gas (Ga) for smoke elimination and deodorization. When the temperature controller (116) detects that the outlet temperature of the secondary combustion chamber (77) has reached a set temperature, for example, 500 to 650 ° C, the temperature controllers for the damper and burner (102) ( 103) commanding the second and third dampers (Db) (Dc) to open and the first damper (Da) to close, and exhaust heat gas (Xa)
Is supplied from the chimney (64) through the reflux pipe (67) to the space (63) of the drying furnace (42) as dry hot air (H). Since the exhaust heat gas (Ga) has a high temperature of 500 to 650 ° C, the temperature inside the screw drum (52) of the drying chamber (51) is raised to 300 ° C. Then, after continuously heating the screw drum (52), the screw drum (52) is returned to the chimney (64) from the discharge pipe (72).
At the same time, the heating burner (7
3) automatically and continuously switches from high combustion to low combustion by proportional control, and finally stops.

However, when the temperature inside the screw drum drops to 300 ° C or lower due to the incineration in the incinerator, the dampers (Da) (Da) ( Db) (Dc) opens and closes to heat the burner (73)
Restarts. That is, each damper (Da) (Db) (D
Rotate c) in the open or closed directions by a predetermined angle to control the semi-open state. Incinerator for dry heat source (43)
The exhaust heat gas (Ga) or the heating burner (73) is appropriately switched, the temperature inside the screw drum is constantly kept at 300 ° C, and the drying of the cut grass (Xa) is smoothly promoted.

Here, a large amount of grass turf (Xa) is obtained in the summer (May-September), but shrub leaves, which become combustibles, are relatively small, and exhaust heat gas (Ga) required for drying is obtained. If the amount of heat is insufficient, the first, second, and third select switches (SS
1) (SS2) (SS3) is switched to the automatic side (however, after switching the second select switch to stop), the same as the above basic operation, from the hopper section (40) to the drying oven (42) the grass turf (Xa )
Supply. Then, the drying heating burner (73) is ignited to operate the drying furnace (42) independently to dry the turfgrass (Xa) and supply it to the incinerator (43). Therefore, general garbage is also supplied into the incinerator (43) to burn combustible materials mixed with dry grass. At the same time, the drying heating burner (63) of the drying furnace (42) is automatically stopped when the temperature reaches a certain temperature. Then, the exhaust heat gas (Ga) is supplied from the incinerator (43) to the drying furnace (42) and the drying may be continued in the same manner as above. Further, in winter, there is almost no incineration of turf grass (Xa), and most of it is flammable waste such as shrub leaves, so it can be incinerated simply by operating the incinerator (43). Therefore, the first, second, and third select switches (SS1), (SS2), and (SS3) are switched to the manual side, and the drying furnace and the incinerator are manually operated appropriately individually or automatically.
