Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an incinerator that can efficiently and completely burn wastes containing various chemical products.

[0002]

[Prior Art]

 Conventional incinerators that incinerate waste have a complicated structure and it is difficult to completely burn it, but if it burns, it emits toxic gas, produces a large amount of smoke, and produces a large amount of smoke. There are various problems such as the generation of ash and the difficulty of cleaning up.

[0003]

[Problems to be solved by the device]

 The present invention solves all of the problems of the prior art, has a simple structure and is easy to completely burn, does not generate toxic gas, and produces less smoke and ash. The incinerator is easy to dispose of.

[0004]

[Means for Solving the Problems]

 The incinerator of the present invention forms a primary combustion chamber and a secondary combustion chamber by partitioning the inner side wall of the cylindrical outer wall on the floor plate to form a primary combustion chamber and a secondary combustion chamber. Along with the lid, the inlet can be opened and closed.In addition, a plurality of primary air inlets are provided in the lower part of the outer wall in a multi-tiered manner, and the outer wall side is raised to face these primary air inlets. The rostrut is arranged in an inclined state, a secondary air intake is provided in the vicinity of the primary air intake, and the secondary combustion chamber is provided with a combustion gas outlet on the inner wall to communicate with the primary combustion chamber. A secondary air supply port is provided so as to face the combustion gas outlet, and a chimney is provided upright at the upper end of the secondary combustion chamber.

[0005]

[Action]

 The primary air inlets, which are provided in multiple stages in the vertical direction, can burn all kinds of wastes in a suitable state by selecting and using them properly in consideration of the nature and amount of the wastes to be burned. When the primary air intakes are arranged in multiple stages, the waste with less gas generation opens the uppermost primary air intake and burns a large amount of waste. Waste that generates a large amount of gas opens the primary air intake in the pit, reduces the amount of waste, and burns, reducing the amount of gas generated. In addition, when a large amount of plastics burns, it easily melts in heat and may flow down to the bottom of the rustle and burn, so in this case, open the bottom primary air inlet to remove the intake air. All flow underneath the grate and the largest amount of wind is blown in, completely burning what has flowed under the grate. When the waste is thrown into the primary combustion chamber through the inlet, and one of the primary air intakes is selected and opened according to the nature and amount of the waste, and it is ignited and burned, a layer of heat is formed on the grate. .. This hot layer becomes hot due to the fast flow of primary air, and its radiant heat causes the combustible gas of the waste in the upper layer to be emitted to form a carbonized layer. The combustible gas merges with the flow of primary air, mixes while passing through the high temperature layer, and completes combustion. These series of operations are repeated while there is waste in the primary combustion chamber.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes an incinerator having a primary combustion chamber 2 and a secondary combustion chamber 3, and these primary combustion chamber 2 and secondary combustion chamber 3 have a cylindrical outer wall 5 provided on a floor plate 4. The inside is partitioned by the inner wall 6 and provided adjacently. A combustion gas outlet 7 is opened in the lower part of the inner wall 6 to connect the primary combustion chamber 2 and the secondary combustion chamber 3 to each other. A waste input port 8 is opened on the upper side surface of the primary combustion chamber 2, and the input port 8 is closed by a lid 9 so as to be openable and closable.

Further, upper and lower three-stage primary air inlets 10a, 10b, 10c and a pair of left and right secondary air inlets 11, 11 are provided at the lower front portion of the outer wall 5. Then, a loss tank 12 in which a large number of long rods are arranged is provided in the primary combustion chamber 2 so as to face the primary air intake ports 10a, 10b, 10c. The grate 12 is installed so as to be inclined so that it is higher on the outer wall 5 side and lower toward the inner wall 6. A space for accumulating the fallen ash is provided below the rostrut 12, and ash outlets 13 are provided at the lower part of the front and side surfaces of the outer wall 5 so as to communicate with this space.

Each of the secondary air intakes 11 and 11 is configured to adjust the amount of air taken in by opening and closing the damper 14. The secondary air taken in from these secondary air inlets 11, 11 passes through the passages 15, 15 provided so as to surround the primary combustion chamber 2, and faces the combustion gas outlet 7 formed in the inner side wall 6. In addition, the air is discharged from the outlet 16 to the secondary combustion chamber 3. A chimney 17 is provided upright on the upper end of the secondary combustion chamber 3. As shown in FIGS. 4 and 5, the rostruts 12 are arranged in two stages, one at a different position from the other, and the lower one is at the lower edge of the combustion gas outlet 7 opened at the inner wall 6 at the rear end. In addition, in the upper one, the rear part is bent upward and the inner end is fixed to the inner wall 6.

Next, the operation of the incinerator 1 of the present invention configured as described above will be described. The lid 9 is opened, and the waste to be incinerated is introduced into the primary combustion chamber 2 through the input port 8 and ignited through any of the primary air intake ports 10a and 10b. At this time, the wind drawn from the side of the chimney 17 flows along the shortest course connecting the primary air intakes 10a, 10b, 10c and the combustion gas outlet 7, but most of it is due to the resistance of the waste. As shown by the arrow in FIG. 6, the wind flows below the rustle 12 near the primary air intake ports 10a, 10b, 10c and serves as a secondary air. Then, a part of the wind is used for combustion through the waste gap and goes to the combustion gas outlet 7. When passing through the combustion gas outlet 7, the secondary air blown out from the outlet 16 above it and the primary air flowing into the bottom of the rostrut 12 merge and enter the secondary combustion chamber 3 to mix and mix. It becomes gas and burns. Although the first smoke emitted from igniting the waste is very thin, it gradually thickens as the fire turns, and by the time the ignition point is reached, the tip of the flame reaches the secondary combustion chamber 3 where it is ignited and extinguished several times. After returning, it becomes a stable combustion state. At this time, since all the smoke is converted into heat, the flow of wind rapidly increases and the burning speed increases. In this way, depending on the quality of the waste, the smoke around the fire disappears about 15 to 20 seconds after ignition, depending on the quality of the waste.

The waste material burned as described above is turned into heat, and the heat of the heat becomes high due to the passage of a very fast-flowing wind. The combustion temperature is about 1300 ° C for a mixture of petroleum products and about 1100 ° C for a material like wood, and the radiant heat causes the waste gas in the upper part of the fire to be discharged. As shown by the arrow in FIG. 6, the gas flow rises from the rear part of the primary combustion chamber 2 and descends to the front part, merges with the primary air taken in from the primary air inlets 10a, 10b, 10c, burns, and burns. Pass through.

Each of the primary air intakes 10a, 10b, 10c, which are provided in a multi-tiered structure with different heights, has a lid on the front surface, and the primary air intakes are opened depending on the amount of waste gas generated. Change the height to adjust the amount of combustion. For example, in the case of waste with a small amount of gas generation, the primary air intake 10a in the upper part is opened and a large amount is burned to increase the amount of gas. Further, in the case of waste that generates a large amount of gas, the central primary air intake port 10b is opened to reduce the amount of gas and reduce the amount of gas. In addition, when a large amount of plastics burns easily because it melts into heat and flows down to the bottom of the rostrtor 12 and burns, all the wind is below the rostrul 12 by opening the lowest primary air intake port 10c. The largest amount of wind is sent to flow through. In this way, by selectively using the primary air intakes which are provided in multiple stages in the upper and lower stages, it is possible to burn different kinds of wastes under optimum conditions.

[0012] However, since wastes having different properties are mixed and the amount of gas generated is different, it is not possible to satisfy certain conditions. Therefore, complete combustion has been difficult, but as described above, It can be solved by combustion using the incinerator 1 of the invention. For example, when a plastic or the like that generates a large amount of gas burns, the flame becomes large, and the flame cannot pass through the space alone, and the flame flows under the rustle 12 as it wraps around the space. The radiant heat is attenuated, the amount of gas generated is reduced, and an appropriate amount is maintained for combustion. Such a series of operations are automatically performed within the combustion range of the primary air intake ports 10a and 10b depending on the type of waste, and complete combustion is possible. In this way, the amount of combustion of the waste itself is controlled, and the functions of the primary combustion chamber 2, the secondary combustion chamber 3, and the chimney 17 are fully exerted, so that the waste can be incinerated without producing smoke or odor.

In addition, as for the fine wastes, the small fires, the melted plastics, etc., which have fallen under the rostrtor 12, most of the flames and primary air burned in the primary combustion chamber 2 are in the rostrtor 12. As it flows downward, the bottom of the rustle 12 acts as a sub-combustion chamber, burning everything that burns to ash. Therefore, the amount of ash is extremely small.

[0014]

[Effect of the device]

 As described above, the incinerator of the present invention has a simple structure and good combustion efficiency, and the smoke disappears quickly and the amount is small. And, it is possible to complete the combustion under high temperature condition by the combustion method using the fire. In addition, by selecting and opening multiple primary air intakes in multiple stages, the amount of combustibles can be adjusted, and the amount of waste to be incinerated automatically depends on the amount of gas generated from the combustibles. It has many advantages such as that it can be adjusted, and that it does not generate toxic gas due to complete combustion, and that the amount of ash is extremely small.
