Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry incinerator for a golf course which can incinerate any combustible waste including lawn turf discarded from a golf course.

[0002]

2. Description of the Related Art In golf courses, various objects such as green (bent grass, korai grass), cut grass on fairways, hay from forests and the like, thinned wood, general garbage, kitchen garbage from restaurants, etc. are discarded. Has been disposed of.

Of these, relatively burnable hay and thinned wood which do not contain much water are incinerated by a general incinerator provided in a golf course. However, freshly cut bent grass and the like have a large amount of water (85 to 90
%), And it is in a hardened state without any gaps, so it cannot be incinerated with a normal incinerator.

[0004]

For example, even if cut grass containing a large amount of water is directly introduced into a burning incinerator, only the surface portion of the mass is burned and the inner portion remains unburned. When the amount of the cut turf is large, there is a possibility that the flame of the incinerator may be extinguished due to the water content.

[0005] A method of excavating a buried hole in the ground for filling lawn turf, kitchen garbage and the like that cannot be incinerated in this way can be considered.
However, cut turf emits an unpleasant odor and contains a large amount of pesticides. Therefore, if it is buried in the ground as it is, the contained pesticides are diffused by rainwater or the like and cause pollution.

In order to incinerate the cut turf in a general incinerator, it is necessary to sufficiently dry the turf before putting it into the incinerator to reduce the water content to at least 60% or less. However, ordinary golf courses do not have facilities such as a drying furnace for drying grass turf in a short time. Further, if the drying oven is installed separately from the incinerator, the equipment becomes large and the cost increases.

[0007] Therefore, the present invention provides a method for incinerating waste containing little moisture in an incinerator, drying the cut grass using heat generated at that time, and drying the cut grass (hereinafter referred to as "drying grass"). The aim is to make it easy to incinerate turf, garbage, etc. in ordinary incinerators.

Next, the dry incineration process according to this embodiment will be described. First, the combustible waste (Y) charged in the hopper (3) is charged into the incinerator (31) from the charging stage (38) by operating the cylinder (40),
It is ignited by an ignition burner (42). The waste heat gas (G) generated at the time of incineration is converted into smoke-free waste heat gas (G ′) by incinerating smoke, dust and the like by the afterburner (43) in the secondary combustion chamber (33). The waste heat gas (G ′) is blown from the chimney (45) of the incinerator (31) by the blower (47) via the reflux pipe (48) to the gas inlet (2) of the drying furnace (10).
2). This waste heat gas (G) is 600 to 65
Due to the high temperature of 0 ° C., the screw drum (12) surrounded by the thermal insulation (13) has a temperature of 500 ° C. in the outer space (21) and 200 ° C. in the inner cavity (16).
The temperature is raised to about ° C.

Next, the cut grass (X) in the hopper (3) is transported into the screw drum (12) by the screw conveyor (4). Since the screw drum (12) is sufficiently heated, the radiant heat is released from the fins (14) and the turf scraping pieces (15), and the turf (X) is dried. In addition, the cut grass (X) is a piece of raw grass (1
By 5), it is lifted obliquely upward along the fins (14), falls down, and is gradually conveyed to the front of the fins (14).

In this transporting process, the cut grass (X) is sufficiently loosened from the dense state to be separated, and is stirred while being sufficiently heated by the action of the radiant heat as in roasting. In a short time, the water content becomes 60% or less.

Thus, the cut grass (X) is taken out of the outlet (20).
In the stage where the dry grass (X ') reaches 60%, the dried grass (X') having a moisture content of 60% or less is transferred by the transport fan (30) together with the air containing the off-flavor in the screw drum (12) to the conveying pipe (29). Is supplied to the dry turf charging port (32a) of the incinerator (31).

The incinerator (3) is inserted through the dry grass input port (32a).
The dried turf (X ′) introduced into the primary combustion chamber (32) of 1) can be easily incinerated together with the waste (Y) that has already been burned. At that time, when the intensity of the thermal power becomes weak, the ignition burner (42) is automatically operated as appropriate to maintain the thermal power constant. Furthermore, general garbage other than turf (hay, kitchen garbage, vinyl, thinned wood, etc.) may be additionally input from the garbage input port (32b).

The waste heat gas (G) including smoke and the like generated by the burning of the dried turf (X ′) and general garbage (Y) is completely removed by the afterburner (43) in the secondary combustion chamber (33). It is burned and turned into waste heat gas (G ') for deodorization and deodorization. Part of the waste heat gas (G ′) discharged from the secondary combustion chamber (33) is sent to the heat exchanger (50). The heat exchanger (50) is supplied with fresh air (A) by a blower (51), and the fresh air (A) is
The heat of the secondary waste heat gas (G ') is absorbed and becomes hot air from the nozzle (34) through the supply pipe (52) to become the primary combustion chamber (3).
2).

The high-temperature and oxygen-containing fresh air (A) further dries the dried turf (X ') and the garbage (Y) and burns the dried turf (X') and the garbage (Y). Further promote.

On the other hand, the waste heat gas (G ') which has passed through the heat exchanger (50) and has completed heat exchange with the fresh air (A) and the waste gas directly discharged from the secondary combustion chamber (33). The hot gas (G ′) is supplied from the chimney (45) to the space (21) of the drying oven (10) through the reflux pipe (48). This waste heat gas (G ′) is supplied to the screw drum (1) as described above.
After the continuous heating of 2), it is returned to the chimney (45) again from the discharge pipe (49) and sent to the dust collector (J).

As described above, in this embodiment, the incinerator (31) is divided into two parts, and the dried turf (X ') and the like are burned in the primary combustion chamber (32). G) is further completely burned in the secondary combustion chamber (33), and fly ash and the like are removed by the dust collector (J).
No waste odor, no smoke, no dust, etc. remain in the waste heat gas (G ′) discharged from.

Further, the turf (X) is dried using the waste heat of the waste heat gas (G ′), and the first incinerator (3) is dried.
Since the fresh air (A) sent to 1) is also heated, the combustion energy can be used very effectively.

Further, the odor generated in the drying furnace (10) together with the drying turf (X ') can be air-conveyed to the incinerator (31) by the transport fan (30). Can be.

In particular, since the air is conveyed by the transport fan (30), the drying furnace (10) can be arranged below the incinerator (31), and both can be extended by extending the conveying pipe (29). Can be arranged apart from each other.
According to this air conveyance, the dried turf (X ′) can be uniformly dispersed and continuously introduced into the incinerator (31), so that the combustion efficiency is greatly improved.

In addition, since the hot air is also blown out from the nozzle (34) on the hearth, the combustion of hard-to-burn materials is promoted, and the primary combustion chamber is used together with the hot air from the nozzle (34) on the furnace wall. (3
2) The inside can be maintained at a high temperature, and the object to be incinerated can always be completely burned. When the temperature in the incinerator (31) becomes high, the burner (4) is controlled by controlling the fuel oil amount of the ignition burner (42) and adjusting the ejection amount of the air (A).
Since 2) can be automatically controlled to maintain complete combustion, a significant reduction in fuel efficiency can be achieved.

As a result, all combustible waste (Y) at the golf course, such as bent turf coming from the golf course, cut grass (K) such as Korai turf, thinned wood, kitchen garbage discarded from restaurants, etc., is summarized. It is possible to incinerate quickly and inexpensively.

According to the present embodiment, although the amount of residual ash can be reduced because the complete combustion rate is high, the nozzle (34)
Is opened upward, so that the residual ash and the like are easily clogged in the nozzle (34). Cleaning of the residual ash that has entered the nozzle (34) is performed as follows. Activate a cleaning blower (not shown) to send compressed air into the pipe (35). The compressed air causes the residual ash in the nozzle (34) to be discharged into the first combustion chamber (32), and the residual ash falling in the pipe (35) to the outside through a residual ash outlet (37) opened. To be discharged.

In the first embodiment described above, the drying furnace (1
0), a transport fan (30) is connected to the front end. However, the present invention is not limited to this, and as shown in FIG.

May be automatically input to the dry grass input port (32a). In the second embodiment, the bucket conveyor (60)
A belt (V) is stretched between one end shaft and the motor (61). However, since the other configuration is almost the same as that of the first embodiment, the same reference numerals as those shown in FIG. The description is omitted by attaching to 2.

In addition, the incinerator (7
In 1), as shown in FIG. 3, a primary combustion chamber (72) and a secondary combustion chamber (73) are separated into separate chambers, and both chambers are connected by a gas passage (75).

Further, an inclined portion (72a) is formed below the waste input port (32b) of the primary combustion chamber (72), on which the waste (Y) and the like can be temporarily placed. A pusher (80) is provided below (72a) so as to face the ash outlet (32c). This pusher (80)
Is extendable along the hearth by the cylinder (81) to the position of the ash outlet (32c).

According to this embodiment, the bucket conveyor (6
0) Dry turf (X ') is incinerated at a fixed rate (31)
, The stable incineration treatment is possible. In this embodiment, as shown in FIG.
Air and the like filled in the screw drum (12) are discharged to the chimney (45), and the odor and the like can be removed by the dust collector (J).

According to the present embodiment, the kitchen waste (Y) containing water can be dried in the process of dropping from the inclined portion (72a) toward the hearth. The garbage (Y) or the like that has dried and dropped on the hearth is extruded to the center of the hearth while being stirred by the pusher (80), so that it is uniformly incinerated without generation of unburned residue. Even when kitchen waste (Y) or the like is additionally charged, it can be efficiently distributed on the hearth by the pusher (80), so that constant combustion can always be maintained.

The ash remaining in the primary combustion chamber (72) is pushed out to an ash outlet (32c) by a pusher (80) and discharged to the outside of the incinerator (71).

Further, according to the present embodiment, since only smoke and odor are sent from the primary combustion chamber (72) to the secondary combustion chamber (73), the processing in the secondary combustion chamber (73) is performed. Is more secure and reliable than the first embodiment.

FIG. 4 shows another embodiment in which the cut grass (X) is transported by a bucket conveyor (65) instead of the screw conveyor (4). Bucket conveyor (6
Since the configuration of 5) itself is the same as that of the bucket conveyor (60), the description is omitted, but in the present embodiment, the hopper (3)
This is effective when it is necessary to dispose it at a position lower than the drying furnace (10).

FIGS. 5A and 5B show the incinerator (71).
Another example of the hearth used for the above is shown. By arranging the hearth (77) in an arch shape as shown in FIG. 5 (a), dried turf (X ′), kitchen garbage (Y), etc. can be evenly dispersed in the furnace. As shown in FIG. 5 (b), by arranging a plurality of arched hearths (78), the combustion efficiency is further improved and cleaning becomes easier.

In each embodiment, the drying furnace (10)
Although the incinerators (31) and (71) are arranged side by side in the horizontal direction, the arrangement is not limited to this and can be changed as appropriate. For example, a drying oven (10) is stacked on top of the incinerators (31) and (71). Is also good. According to this arrangement, the transport fan (30)
