Description

[Detailed description of the invention] (Target field) When conventional small natural combustion incinerators are used, raw food is considered difficult to burn waste and is generally not disposed of by incineration.

Furthermore, rubber and petroleum-generated waste emit a torrential amount of black smoke, and in light of the growing environmental awareness in recent years, careless incineration should be avoided.

This invention utilizes the combustion power of combustible garbage as self-sufficient energy in the furnace, incinerates the combustible garbage that is fed in at the same time, and effectively controls the release of black smoke from highly smoky garbage.

(Structure and function) Recognizing the positional circumstances and mutual influence of the ignition heat generation of adjacent combustion chambers, which are separated above and below by crosspieces in a closed space for the purpose of packing and burning garbage, a series of The structure causes artificial air supply interference.

Its action is to efficiently utilize self-supplied energy by burning the input waste to achieve dry carbonization.

Some operations are required depending on the quality and condition of the material to be processed, and examples will be described below with the characteristics of the three conditions. Numbers in parentheses are symbols shown in the drawing.

Condition A. Kitchen garbage 50% raw garbage and 50% combustible garbage are mixed into the carbonization incinerator in the upper chamber, and 80% combustible garbage and 20% of other garbage are mixed into the main incinerator in the lower chamber. Pack 50% to 90%.

Set the opening of ventilation valve 2 to about 30%.

The ignition first ignites the lower chamber, then the upper chamber.

Place trash that ignites well near the input port in the upper chamber.

With the air intake 14 fully open and the small windows of the upper and lower doors 8 and 11 fully open, confirm the rise of the fire in the lower room, and then fully close the air intake 14.

Combustion in the lower chamber continues at a slow pace with the flame intensity limited by air intake only through the small window 15. In the upper chamber, the fire that burns near the input port spreads to the mixed combustible waste, increasing the temperature inside the furnace and widening the gap for hot air to enter.

When the flame in the lower chamber subsides and transitions to charcoal combustion, the upper chamber maintains conditions filled with dry air and hot air, continuing to burn as dryly as possible. The combustibles remaining in the process of cooling down the furnace remain there and serve as good material for the next combustion.

Condition B. Rubber, petroleum-generated waste 50% rubber and petroleum-generated waste are mixed with about 50% of other garbage into the carbonization combustion chamber in the upper chamber, and the main combustion occurs in the lower chamber.
Pack 60% or more of combustible waste to 50% to 90% of the chamber volume.

Set the opening of the vent valve 2 to about 10%.

The ignition first ignites the lower chamber, then the upper chamber.

The air intake 14 is fully opened and the small windows of the upper and lower doors 8 and 11 are fully opened to confirm the rise of fire in the lower room, and the air intake 14 is fully closed. Furthermore, small windows 1 on the upper and lower doors
5 and 16 by approximately 50% to limit air supply.

This type of waste is carbonized into gas, and a flame is released from the upper chamber to the lower chamber, creating a swirling flame inside the main combustion chamber of the lower chamber. And the soot and smoke released has been significantly improved.

The molten waste that is delayed in gasification adheres to other mixed waste or drips into the lower chamber and is similarly burned.

Condition C. Approximately 20% of combustible garbage is mixed with combustible garbage. There is no need to distinguish between the upper and lower chambers.

The ignition first ignites the lower chamber, then the upper chamber.

Set the opening of ventilation valve 2 to about 20%.

Although it is not necessary to adjust the air intake 14, more effective results will be seen if it is fully closed after the fire has built up.
