Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) This invention completely incinerates waste such as livestock excrement without producing any odor, and uses the combustion waste heat to e.g. This invention relates to an incineration device for livestock manure, etc., which can be used for heating garden greenhouses, drying livestock manure, grains, etc.

(Prior Art) A conventional livestock manure boiler has a combustion chamber section and a water heater section that are integrally provided.

(Problems that the invention aims to solve) For this reason, the combustion chamber was cooled by water in the water heater or hot water, making it difficult for the temperature inside the combustion chamber to rise, and since the combustion air was blown directly into the combustion chamber from outside. In winter, the temperature inside the furnace is lowered, which tends to cause incomplete combustion and generates odor.
In addition, livestock excrement is often in the form of dry lumps, which makes it extremely difficult to burn as it is, and when crushed, some of it turns into powder, making it difficult to incinerate this powder. Ta. The purpose of this invention is to provide an apparatus for incinerating livestock excrement, etc., which can eliminate the above-mentioned drawbacks and also makes it possible to utilize combustion waste heat.

(Example) The structure of the incineration apparatus for livestock excrement, etc. according to this invention will be explained in detail based on the illustrated embodiment. As shown in FIG. The hopper section A is comprised of a combustion waste gas processing section C, and the hopper section A has ribbon screws 1 disposed in the lower part of the hopper A, as shown in an enlarged view in FIG. The hopper A is provided with a plurality of (four, second

Furnace tube 91 of a furnace tube fire tube type hot water boiler 9 (see Fig. 5), which is provided with an outgoing pipe 7 and a return pipe 8 _.
And it communicates with the chimney 11 through the smoke pipe 10.

In addition, a secondary air blower 13 installed separately outside the incineration chamber B is installed directly below the discharge end 3 of the screw feeder 2 that opens into the incineration chamber B.
A secondary air discharge pipe 14 for discharging the secondary air sent from the incineration chamber B (see Fig. 2) is installed horizontally. A jet nozzle 15 and a jet nozzle 16 facing upward and forming an angle of 45 degrees with the direction of the jet nozzle 15 are provided.

In addition, in FIGS. 1 and 2, 17 is an ash pit, 18 is a hot water temperature regulator, 19 is a motor that rotates the ribbon screw 1 and the screw feeder 2 via chains 20 and 21, and d indicate pipe rostle respectively. Incidentally, it goes without saying that the ignition burner B is not provided in a device that is ignited with a match or the like.

(Function) Since this device has the above-mentioned configuration, when waste such as livestock dung is put into the hopper part A, the livestock dung, etc. is placed in the center by the rotation of the ribbon screw 1 whose left and right sides are reversely screwed. The animal feces, etc. are collected, mixed and crushed, and become powder particles that fall onto the lower screw feeder 2... and are sequentially sent to the incineration chamber B without causing any cross-linking phenomenon in the hopper section A. .

Incineration chamber B is lined with refractory bricks 4, the primary air is preheated in a heat exchange box 6, and a hot water boiler 9 is provided separately, so animal excrement, etc. is ignited with a burner, and the interior of the room where this is combusted quickly rises. It can be heated and maintained at a high temperature (approximately 800 degrees Celsius or higher), and the livestock manure that is sent one after another passes through the insulation material 3 before reaching the discharge end 3.
Combined with the fact that it is preheated in the tube covered with Note that the burner automatically shuts off after a certain period of time.

The waste gas produced by the combustion is discharged to the chimney 11 through the furnace tube 91 and the smoke tube ₁₀ of the furnace tube hot water boiler 9 provided as the combustion waste gas treatment section C.
The waste heat is sufficiently recovered in the furnace and smoke tube type hot water boiler 9, and the hot water is sent out from the outgoing pipe 7 and returned to the hot water boiler 9 through the return pipe 8, during which it is used for heating livestock barns, gardening houses, etc., and drying livestock manure, grain, etc. It can be carried out.

The incineration chamber B is provided with a step-like grate 5 below the discharge end 3 of the screw feeder 2, and primary air from the grate 5 is heated through a heat exchange box 6 to a temperature of 70° to 70°. Since the hot air of 120°C is blown out, the incineration chamber B is not cooled by the primary air and can maintain a high temperature of 800°C or more as mentioned above, and the granular livestock excrement is disposed of in the stepped shape. Since the parts fall one after another, they are completely combusted and incinerated, and if the fire grate 5 is provided with weir plates C here and there, sparks remain, making it easy to re-ignite.

Furthermore, if the secondary air discharge pipe 14 is provided directly below the discharge end as described above, the horizontally oriented jet nozzle 15 and
With the spout 16 facing upward at 45°, the discharge end 3
Powdered livestock excrement, etc., which is difficult to burn, is blown up and becomes suspended in the flame airflow, and can be instantly combusted. Incidentally, the ash after complete combustion falls into the ash pit 17 through the pipe roaster d and is collected therein.

The secondary air jetted out from the jet nozzle 16 facing upward at 45 degrees hits the discharge end 3, thereby preventing the discharge end 3 from being directly hit by the flame and being damaged, thereby contributing to improved durability.

[Effect of idea]

This device has the above-mentioned structure and function, and it thoroughly mixes and pulverizes livestock manure, etc. in the receiving hopper without causing any cross-linking phenomenon, and completely burns it in the incineration chamber, which can maintain a high temperature, thereby eliminating odor. The high-temperature waste heat is sufficiently recovered by the smoke tube hot water boiler 9 provided as the combustion waste gas treatment section C without being dissipated, and can be used for heating livestock barns, garden greenhouses, etc., drying livestock manure and grain, etc. can.
