Abstract

PROBLEM TO BE SOLVED: To lessen the quantity of heat generated for a unit time and the amount of combustion products and to eliminate restrictions on a place of installation by providing a compressing-pressing means which compresses garbage held in a garbage holding chamber and presses it on a fire grate so as to burn the garbage continuously on the surface of the fire grate on the garbage holding chamber side. SOLUTION: To incinerate garbage 10 and reduce the amount thereof, a weight 11 is put on the garbage 10 thrown in a garbage holding chamber 8 and the garbage 10 is compressed and pressed on the upper side of a fire grate 7 by the weight 11. When air is supplied toward the lower side of the fire grate 7 from each air supply nozzle 16 and a fire is made by an electric heater 18 in this state, the garbage 10 is burned gently. Incineration ashes produced at this time fall down through the fire grate 7 and the garbage 10 not yet burned are supplied sequentially and burned in succession. Since air is not diffused in the upper part of the garbage holding chamber 8 on the occasion, the amount of smoke produced by incomplete burning of the garbage 10 is lessened.

It

Next, the operation of this embodiment will be described. When incinerating and reducing the weight of the refuse 10 in the refuse incinerator 1, a weight 11 is placed above the refuse 10 introduced into the refuse storage chamber 8 through the refuse inlet 5a. And the dust inlet 5a is sealed with the lid 6. As a result, the dust 10 in the dust storage chamber 8 is compressed by the weight 11 and pressed against the upper surface of the rostrut 7. In this state, the air supply nozzles 16 ...
When air for combustion is supplied from the electric power source and ignited by the electric heater 18, the dust 10 in the dust storage chamber 8 becomes trash 7.
Only in the surface facing the garbage storage chamber 8 side, the combustion can be gently continued. That is, 1 garbage in the garbage storage room 8
Since 0 is in a compressed state and the dust inlet 5a is closed by the lid 6, the air supplied to the combustion chamber 9 is prevented from diffusing above the dust storage chamber 8 as much as possible. The compressed dust 10 is slowly combusted only in the vicinity of the upper surface of the rostrut 7 to which air is supplied from the air supply nozzles 16. When the incinerated ash passes through the roster 7 and falls, the unburned dust 10 is sequentially supplied to the vicinity of the upper surface of the roast 7 and the burning of the dust 10 is gradually continued. Moreover, since the air does not diffuse to the upper part of the dust storage chamber 8, the amount of smoke generated by the incomplete combustion of the dust 10 can be reduced as much as possible.

Further, since the rostrut 7 is formed in a bowl shape that bulges toward the combustion chamber 9, it is possible to make the thickness of the combustion layer on the upper surface of the rostrur 7 substantially uniform over the entire upper surface of the rostrut 7. Therefore, it is possible to stabilize the combustion. Further, when the weight 11 comes into contact with the regulation surface 5b and reaches the lower limit position, the compressive force to the dust 10 present on the upper surface of the roster 7 is released, and the dust 10 can be reliably burned to the end. is there.

In such a refuse incinerator 1, since the refuse 10 is continuously burned in small amounts, the amount of heat generated per unit time does not increase, and therefore the incinerator main body 5 is prevented from reaching a high temperature. However, when used at home or the like, it is possible to eliminate the restriction on the installation place due to the high temperature of the incinerator 1. In addition, the continuous combustion of the dust 10 suppresses the amount of combustion gas generated per unit time, and by sufficiently supplying the combustion air, the generation of unburned gas is suppressed as much as possible, so that the combustion gas discharge means 19 is discharged to the outside. It becomes possible to purify the exhaust gas discharged as much as possible. Therefore, the refuse incinerator 1 can be installed in each household with almost no problem, and the garbage 10 is incinerated frequently when the garbage 10 is generated, as if the garbage 10 was discarded. , It is possible to reduce the weight.

Moreover, the amount of air supplied by the air supply means 12 into the combustion chamber 9 may be a relatively small amount sufficient to burn the dust 10 in the vicinity of the roster 7, and the capacity of the blower 13 is relatively large. It can be small. Further, since the air supply nozzles 16 are arranged such that the open ends thereof are located in the height range of the roster 7, the air from the air supply nozzles 16 ... It is possible to efficiently scatter, and to stably and continuously burn the dust 10 on the roster 7.

Since a relatively small amount of air supplied from each air supply nozzle 16 produces a swirling flow in the combustion chamber 9, the volume of the combustion chamber 9 is made relatively small and then the combustion chamber 9 is made smaller.
The combustion gas discharged from the combustion gas discharge means 19 is made to have a relatively long secondary gas retention time to secure the time required for the combustion of the unburned gas in the combustion chamber 9 to reliably perform the secondary combustion. Smokeless and odorless can be promoted.

Not only when the electric heater 18 is ignited,
Power may be continuously applied during combustion.

The combustion gas discharged from the refuse incinerator 1 is introduced into a heating tank 22, and in this heating tank 22, the amount of heat from the combustion gas is stored in the food waste processing tank 2 and both volume reduction processing tanks 3 and 4. Transmitted. As a result, the temperature of the gas discharged from the exhaust pipe line 23 can be lowered, and the garbage processing tank 2 can be kept at an optimum temperature suitable for organic processing, and both volume reduction processings can be performed. PET bottle 2 in a state of being pressurized by weights 30 and 31 in tanks 3 and 4
6 and expanded polystyrene 27 and the like can be heated to reduce the volume.

Although the embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments, and various design changes can be made without departing from the present invention described in the appended claims. It is possible to do.

A lid that opens and closes the waste inlet provided in the main body of the incinerator that leads to the waste storage chamber, and gently burns the waste on the surface of the waste storage chamber of the loss stole with the lid closed. Since it is equipped with a compression / pressing unit that compresses the waste stored in the waste storage chamber and pushes it against the loss stove to continue, the waste that is compressed in the waste storage chamber is gently burned only near the loss stove. It is possible to continue the combustion and to make the amount of heat generated per unit time and the amount of combustion gas generated relatively small, eliminating the restrictions on the installation location when using it at home, etc. Therefore, it is possible to incinerate and reduce the amount of waste by disposing of it frequently.
