Description

  The present invention relates to an incinerator for incinerating waste and the like.

  Before incineration of waste, it was a thing that was easily attached to a smoke can on a drum can, or a large box with a nice appearance, but the inside was simply a box for waste, and the upper part was just connected to the chimney There were many things, but in any case air was not sufficiently introduced into the combustion part, combustion was incomplete and combustion temperature was low, and due to incomplete combustion, a large amount of harmful substances such as dioxin, smoke, soot, etc. Was released into the atmosphere.

  In recent years, environmental pollution has become a problem, and simple incinerators such as those described above can no longer be used, and various types of furnaces that can completely burn waste have been proposed. There were many large expensive items.

  An object of the present invention is to provide a waste incinerator having a simple structure, good combustion efficiency, easy handling, small size, and low cost.

Means for Solving the Invention

  As a result of earnest research on the development of an incinerator to achieve complete combustion, unburned materials are gasified by heat in the combustion chamber and burned in flames by oxygen in the air in which the gas is introduced. However, in general, the temperature does not rise so much and there is not enough air, so incomplete combustion often occurs. Therefore, an auxiliary combustion cylinder is installed in the combustion chamber, the incomplete combustion gas is guided to the auxiliary combustion cylinder, and an external burner is installed. It was found that it is better to raise the temperature with the help of, and to burn completely while supplying air.

  As the auxiliary combustion cylinder, a metal pipe with a diameter of 10 to 25 cm having a length of about half to two-thirds of the inner diameter of the furnace is installed horizontally at the upper part of the combustion chamber. The cylinder has small holes everywhere to suck incompletely combusted gas, and from one side of the auxiliary cylinder, burner flame and air from outside the furnace can be blown as an inlet, Combustion gas discharge port for discharging the combustion gas of the furnace at the place corresponding to the other side of the auxiliary combustion tube is attached to the furnace so that the metal tube is in contact with the auxiliary combustion tube with a little space However, this is also attached at a slight distance from the auxiliary cylinder.

  The upper part of this incinerator has an inlet for incineration and its lid, the lower part has a scraping outlet for scraping ash and its open / close door, and air necessary for combustion. There is an air intake that can adjust the opening.

  At the end of the combustion gas outlet from the furnace, it is connected to a secondary combustion cylinder that rises vertically in order to further burn incomplete combustion gas that could not be burned sufficiently in the furnace at the time of maximum combustion. Small holes are drilled everywhere in the secondary combustion cylinder. The perforated secondary combustion cylinder is covered with a sleeve having a larger diameter that is open only at the lower part so as to surround it. During maximum combustion, incompletely combusted gas blows out from the lower hole of the secondary combustion cylinder, mixes with air and burns, and is sucked into the secondary combustion cylinder from the upper hole. From there, it leads to a chimney for exhaust. The chimney must be tall and good.

The invention's effect

  An auxiliary burner can be installed to guide incompletely combusted gas there, and burner flame and air can be blown into it from the side to completely burn the gas at high temperature. At the time of maximum combustion, a secondary combustion system is attached directly to the combustion gas discharge port of the incinerator in preparation for incompleteness alone, so that no toxic gas or the like due to incomplete combustion is discharged into the atmosphere. This incinerator has a small air intake at the bottom, so that excessive combustion does not occur in the furnace body. Since only the combustion necessary to gasify the incineration occurs, the furnace body is not overheated enough to be distorted by heat and the furnace lasts longer.

  A metal auxiliary combustion cylinder with a length approximately half the inner diameter of the furnace is installed horizontally in the upper part of the incinerator, and there are small holes in the cylinder everywhere. The burner flame and air from the outside of the furnace are used as a blow-in port, and a metal cylinder is attached to the furnace so that it is slightly in contact with the auxiliary-cylinder port. A combustion gas discharge port for discharging the combustion gas of the furnace is attached at a position corresponding to the port, which is also slightly spaced from the auxiliary combustion tube.

  At the upper part of the incinerator, an inlet for injecting the incinerator and its lid are attached. The auxiliary burner is firmly attached to the back of the lid of the incinerator inlet at a certain distance and moves together with the lid. After putting the incinerator into the full incinerator, the auxiliary burner also serves to push the incinerator when the lid is closed. If you ignite the burner, you can quickly ignite the incinerator. In the lower part, there are a scraping port for scavenging ash, an opening / closing door for it, and a small air intake port for adjusting the opening for taking in air necessary for gasification combustion.

  The end of the combustion gas exiting from the incinerator is connected to a secondary combustion cylinder that rises vertically in order to further burn the incomplete combustion gas during maximum combustion. There are holes for mixing with air. A sleeve having a larger diameter and having an open lower portion is covered so as to surround the entire secondary combustion cylinder portion, and the tip of the secondary combustion cylinder is connected to a chimney for exhaust.

  The incinerator of the present invention will be described with reference to the drawings. FIG. 1 is a conceptual diagram showing the structure of the incinerator inlet 2 having a diameter of about 1 m and a height of about 2 m, and an incinerator inlet 2 of about 60 cm across. From the lid 3, an auxiliary combustion cylinder 5 is attached via a support fitting 4. The auxiliary combustion cylinder has a diameter of 12 cm, a length of about 50 cm, and has 15 holes with a diameter of 3 cm.

  A blowing port 6 for blowing air simultaneously with the flame of the burner is attached to the main body 1 on one side of the auxiliary combustion tube 5 so as to be almost in contact with the auxiliary combustion tube, and a burner 7 is set outside thereof. A combustion gas discharge port 8 for taking out combustion gas is attached to the opposite side of the auxiliary combustion cylinder.

  A secondary combustion cylinder 9 is connected to the combustion gas discharge port 8. This secondary combustion cylinder also has 20 holes with a diameter of about 1 cm for mixed combustion with air. The secondary combustion cylinder 9 is covered with a sleeve 10 that is open only at the bottom so as to completely cover it. The tip is connected to the chimney 11 for exhaust.

  A funnel-shaped baffle plate 12 is attached to the bottom of the incinerator so that the incinerated product does not fall to the bottom, and a hole is opened at the center so that ash falls downward. As can be seen from FIG. 2, at the lower part of the incinerator, there are provided a scraping port 13 for scraping ash and a small air intake port 14 for adjusting the opening for intake of air.

  When the incinerator is actually packed in the incinerator and the burner is ignited, the incinerator is immediately ignited and smoothly gasified, and then burned in the auxiliary burner. After about 2 to 3 hours, it is carbonized and no gas is emitted. The burner was turned off, and the charcoal that remained was burning spontaneously, and after a few hours, it became white ash only.

  At the time of maximum combustion, combustion becomes insufficient with only the temporary auxiliary combustion cylinder, but at that time, the flame extends to the secondary combustion cylinder, and is mixed with air through the hole made in the secondary combustion cylinder to complete combustion.

  As described above, in the case of the incinerator of the present invention, the gasified combustion product is completely burned at a high temperature by the auxiliary combustion cylinder and the secondary combustion cylinder, so that no toxic gas is generated. Further, in the incinerator of the present invention, the temperature in the furnace rises and evaporation / gasification occurs from the incinerated material, so that even an object such as sludge can be mixed and incinerated. The incinerator of the present invention is strong because it is made entirely of iron plate, but can be easily scrapped when it is no longer needed.
