Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a waste incinerator that is suitable for incinerating raw grass that has been mowed mainly at a golf course or the like, and the same amount of raw garbage.

[0002]

[Prior art and its problems]

 Conventionally, lawns cut at golf courses are not suitable for compost for agriculture due to problems such as residual pesticides.Therefore, they are dried in the open pile and incinerated using a normal garbage incinerator. There is. This type of conventional refuse incinerator is generally a vertical cylinder type with an air intake under the lower stove and a chimney at the top.

However, in this type of incinerator, it takes a long time to incinerate a lawn in a raw state, and since complete combustion is difficult, a large amount of smoke is generated, which causes a problem of environmental pollution.

On the other hand, as an incinerator for incinerating food waste, a large-scale furnace is mainly used in which a heavy oil burner is used to keep the inside of the furnace at a high temperature and the food waste is put into the incinerator. However, this main incinerator has a problem in that it requires a large-scale flue gas treatment facility, requires a large amount of fuel, and is costly.

[0005]

[Problems to be solved by the device]

 In view of such a conventional problem, the present invention efficiently or completely burns raw garbage having a water content similar to that of raw lawn with a small amount of fuel, and in particular, does not require smoke exhaust treatment equipment. The purpose was to provide a waste incinerator that can be burned in a state.

[0006]

[Means for achieving the object]

 In order to solve the above-mentioned conventional problems and achieve the intended purpose, the gist of the present invention is to provide a ventilation path through a grate in the bottom of an incinerator room where combustible waste is stored, The waste incinerator is characterized in that one end of the air passage is connected to the upper part of the incineration chamber through an upward flue and a burner for igniting a flame is inserted under the roster.

[0007]

[Action]

 The waste incinerator according to the present invention accommodates incinerators such as raw grass in the incinerator leaving a space in the upper part, and emits flame from the burner to the bottom of the rostrut while sending air from the peripheral wall and the bottom. As a result, the incinerated material on the rustle is dried from the bottom and becomes steamy and the incomplete combustion gas rises. On the other hand, in the upper part of the incinerator, the hot air injected under the grate is sent through the flue, so the incinerator in the upper part is completely combusted together with the rising incomplete combustion gas, and the combustion gradually begins. Descend to. When the initial combustion progresses in this way, sufficient heat is generated on the grate and the upper part of the incinerator, and even if the flame from the burner is stopped, the complete combustion is maintained simply by sending air, and the entire combustion is continued. Leading to completion.

On-off valves 12, 12, ..., Which are electromagnetic valves, are provided on the respective branch paths 11a, 11a. Each of the on-off valves 12, 12, ... Is provided with a timer and operates at a time set by the timer. In addition to the on-off valve, each branch passage 11a, 11a, etc. is provided with a manual flow rate control valve 14 for adjusting the opening.

In the bottom wall 3 of the incineration chamber 1, a plurality of air supply pipes 15, 15 ... Are embedded in parallel arrangement, a part of the outer peripheral surface thereof is exposed in the incinerator chamber 1, and a large number of exposed portions are provided. The fumarole 16 is opened (shown in FIG. 5). One end of each of the air supply pipes 15, 15, ... Is projected to the outside of the bottom wall 3 and communicates with one common air supply pipe 17, and the air supply pipe 17 communicates with the common air passage 11 described above. . The air supply pipe 17 is provided with a manual on-off valve 19.

The ceiling wall 4 of the incineration chamber 1 has a plurality of central air pipes 21 and 21 penetrating from the outside into the incinerator chamber 1 from the outside. The air supply pipe 21 is closed at its lower end and has a large number of fumaroles 22, 22 ... Opened around it (shown in FIG. 5). The upper end of each air supply pipe 21 communicates with one air supply pipe 23, which communicates with the common air passage 11 described above. Air is always supplied to the air supply pipe 23. The air supply pipe 23 and the air supply pipe 17 described above may be provided with an opening / closing valve and a flow rate adjusting valve which are electromagnetic valves with a timer.

On the other hand, at the bottom of the incineration chamber 1, on the bottom wall 3, at a space, a roster 25 is installed so as to face the side walls between the side walls 2b and 2d. The rostrut 25 has a plurality of air supply pipes 25a, 25a ... Which are arranged in parallel with each other and communicated with an arch-shaped support pipe 26. Each air supply pipe 25a has a large number of fumaroles 25b, 25b. …… is opened. Further, the support pipe 26 is formed in a hollow shape, and the inside of the support pipe 26 communicates with each of the air supply pipes 25a, 25a ... And the support pipe 26 communicates with the common air passage 11 via an air supply pipe 27. The air supply pipe 27 is provided with a manual on-off valve 28 (shown in FIG. 3).

An air passage 29 is provided under the rostrum 25, and a burner 30 is inserted into one end of the air passage 29 to radiate flame into the air passage 29. The burner 30 is fixed to the door 6a of the ash outlet 6, and the tip of the burner 30 is inserted into the air passage 29 by closing the door 6a.
