Abstract

PURPOSE:To substantially completely incinerate unburned gas, incompletely burned gas with low incinerating cost by providing a heat generating zone at a suitable position in a chimney of a furnace chamber, and providing a heat generating zone formed in a knitted mesh state at an inlet of a flue. CONSTITUTION:A heat generating zone 5 of a knitted mesh state made of nichrome wires, etc., and a spiral heat generating zone 6 or a honeycomblike heat generating zone are provided at suitable positions where unburned gas, incompletely burned gas is stayed or easily passed in a flue inlet 2, a chimney 3 of a furnace chamber 1. When the zone 5 is provided in the flue inlet and the zone 5 and the honeycomblike zone are provided under the chimney, the unburned gas or the incompletely burned gas can be substantially effectively brought into contact with the zone. When the zone 6 made of the nichrome wires, etc., is installed inside a furnace wall 8, unburned gas or incompletely burned gas stayed in the wall can be positively burned.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incinerator for incinerating general-purpose waste and industrial waste, and more specifically, an incinerator structure devised to completely burn unburned gas and unburned gas. It is about.

[0002]

2. Description of the Related Art In a conventional incinerator, when the thermal power in the furnace chamber becomes weak and the temperature in the furnace chamber decreases, unburned gas and incompletely burned gas increase, and those gases are released into the atmosphere as they are. However, it had the drawback of polluting the atmosphere. Conventionally, in order to prevent the release of unburned gas and incompletely burned gas,
Secondary combustion chambers, such as secondary combustion chambers and tertiary combustion chambers, are installed in series from the flue inlet to the outlet, and unburned gas or incompletely burned gas is forced in the combustion chambers with a gas burner. Although it is incinerated, with this method, unburned gas and incompletely burned gas could be burned almost completely, but the equipment cost increases and the consumption of heavy oil as fuel for the gas burner increases. There was a drawback. Further, in a relatively small incinerator such as a household incinerator that incinerates general waste, in order to reduce the equipment cost and the incineration cost, the auxiliary combustion chamber as described above is used. It was not installed at all.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the drawbacks described in the prior art, and does not require an expensive combustion chamber as in the prior art and has a low incineration cost. The purpose is to provide an incinerator capable of almost completely burning unburned gas and incompletely burned gas.

[0004]

[Means for Solving the Problems] Stitches made of nichrome wire, ceramics, ceramic fibers, etc. at appropriate places in the furnace chamber, flue inlet, chimney, etc. where unburned gas or incompletely burned gas is likely to stagnant or pass. It has a tropical, spiral, or honeycomb shape.

[0005]

When the unburned gas or the incompletely burned gas comes into contact with the tropical zone, the unburned gas or the incompletely burned gas is ignited by the heat of the tropical zone and burns almost completely. The mesh-shaped tropical zone can control the size of the soot in the discharged soot smoke by controlling the size of the mesh. In the tropical zone using the nichrome wire, the temperature can be controlled by adjusting the energizing current. The tropics formed of ceramics or ceramic fibers have a heat storage effect and generate far-infrared rays, penetrate the soot particles in the unburned gas or incompletely burned gas, heat the soot particles, and easily ignite. It is effective because it does.

[0006] In the honeycomb-shaped tropical zone, the frequency of contact of the unburned gas and the incompletely burned gas with the tropical zone increases, so that the unburned gas and the incompletely burned gas can be efficiently and completely burned. If the spiral tropical zone is installed inside the circular furnace wall, combustion efficiency can be improved economically.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings showing an embodiment of the present invention, unburned gas or incompletely burned gas easily stagnates or passes through in a furnace chamber 1, a flue inlet 2, an inside 4 of a chimney 3 and the like. A knitted tropical zone 5, a spiral tropical zone 6 or a honeycomb-shaped tropical zone 7 made of nichrome wire, ceramics, ceramic fibers or the like is provided at an appropriate position.

A mesh-shaped tropical zone 5 is provided at the flue inlet, and a mesh-shaped tropical zone 5 and a honeycomb-shaped tropical zone 7 are provided below the chimney.
With the above, since the unburned gas or the incompletely burned gas can almost certainly be brought into contact with the tropical zone, the combustion efficiency is improved.

As shown in FIG. 3, when a spiral-shaped heat-generating zone 6 made of nichrome wire or the like is installed inside the furnace wall 8, oxygen shortage occurs and unburned gas or stagnation in the inner wall occurs. Since non-combustible gas can be actively burned,
It is effective. In addition, 9 is a charging port and 10 is a secondary combustion chamber. Also, the tropical zone may be united to an appropriate size so that it can be attached and detached so that it can be mass-produced economically. In addition,
The heat generation may be controlled by adjusting the current value to be applied according to the temperature in the furnace, the smoke concentration, the odor concentration, and the like.

[0010]

[Effect] Since the present invention is configured as described above,
It has the following effects.

Since the unburned gas or the unburned gas burns almost completely, it is possible to remove odors and soot from the exhaust gas.

The tropics of ceramics or ceramic fibers generate far infrared rays to accelerate combustion.

Combustion efficiency is further improved by forming the tropical zone into a stitch shape or a honeycomb shape.

Since the auxiliary combustion chamber such as the secondary combustion chamber can be omitted, the equipment cost can be greatly reduced.

Since no heavy oil is used, it is clean and saves resources.

Since the tropical zone has a simple structure, it can be mass-produced. The present invention has the above remarkable effects,
It has a high industrial utility value.
