Detailed Description

The waste incineration device of the invention can be made of the following materials, but is not limited to the following materials, for example: stainless steel, refractory ceramics, motors, section steel, a slag extractor, a feeder and the like.

FIG. 1 is a side view showing a structure of a waste incineration apparatus according to an embodiment of the present invention; the waste incineration device of the embodiment of the invention comprises: a furnace body 1; the furnace body 1 is a closed cavity, the top of the furnace body 1 is provided with a feed inlet 70 and a smoke outlet 8, and the bottom of the furnace body 1 is provided with a slag outlet 6.

Generally, the front end of the feeding hole 70 is provided with a feeding device 7, so as to ensure that garbage can continuously enter the furnace body from the upper part of the furnace body for combustion.

And a flue gas guide pipe is arranged outside the smoke outlet 8 to guide out flue gas for treatment.

The slag outlet 6 is used for discharging ash which is fully combusted out of the furnace body.

A support frame 4 and a burner 2 are arranged in the furnace body 1, and at least one rotatable ceramic combustion disc 3 is arranged at the top of the support frame 4; the burner 2 is positioned below the ceramic combustion disc 3; the rotating plane of the ceramic combustion disc 3 is inclined to the horizontal plane; preferably, the angle between the plane of rotation of the ceramic burner disk 3 and the horizontal plane is 15-35 degrees.

The burner is a general term for a device for ejecting fuel and air in a certain manner to perform mixed combustion. The burners are classified into industrial burners, civil burners and special burners according to types and application fields. Is made of corrosion-resistant and high-temperature-resistant materials such as stainless steel or metallic titanium. In the embodiment, atomized fuel mixed with air or oxygen is generally adopted and then sprayed out through a burner to perform active combustion; other combustible gas mixed with air can be used for combustion. The burner of the present embodiment has a mixture gas shower head 20 and a flow rate control valve 21.

The ceramic burning plate is generally made of fire-resistant ceramic by firing, and the general fire-resistant temperature is kept above 2200 ℃. The support frame 4 is generally provided with a rotating shaft 34, and the ceramic combustion disc 3 is rotatably mounted on the support frame 4 through the rotating shaft 34. The shaft 34 is also typically made of a high temperature resistant material, typically a ceramic bearing or a sliding bearing.

A plurality of stirring rods 30 are arranged on the ceramic combustion disc 3, the stirring rods 30 are of tubular structures, and two ends of each tubular structure are used for being communicated with two ends of the ceramic combustion disc 3.

Can guarantee like this that the combustible gas mixture of combustor spun can burn in ceramic burning dish 3 top through puddler 30, avoid rubbish directly to block up the combustor.

The puddler not only plays the stirring effect owing to be protruding ceramic burning dish upper surface, and the most important has introduced combustible gas and has mixed with rubbish to reduce the use amount of fuel at the in-process that lasts the burning, avoid a large amount of rubbish to pile up and can not thoroughly burn.
