Abstract

PURPOSE:To enable a complete combustion to be performed by a method wherein a blower is installed in an incinerater so as to forcibly feed the air injected from the nozzles arranged in a primary combustion chamber. CONSTITUTION:Items to be combustioned are loaded in a primary combustion chamber 3, a blower 8 is operated in simultaneous with the ignition, the air is injected from each of the air injection ports through pipes connected to the nozzles. The injection port 9 near the bottom part of a primary chamber enforces the combustion under an agitating condition by a forced air blowing from each of the directions. The upper injection port 10 has no opposed injection port, so that it causes hot flame gas generated by combustion to be rotated at a high speed along the inner wall. Thus, the flame gas is fed to the secondary combustion chamber 4 through the passage 6 arranged at the upper part while being rotated in a horizontal direction at a high speed. The secondary combustion chamber 4 is constructed as a cylindrical shape and its interior is forcedly rotated in a horizontal direction by injection air from the air injection port 11 made at the passage 6. Thus, the secondary combustion chamber 4 shows a continued high speed rotation due to the fact that the passage 7 for the cyclone 5 is arranged near the bottom part of the cylinder and so a high heat is kept and a complete combustion of the flame is assured.

Description

[Detailed description of the invention] General garbage in government offices, hospitals, etc., documents to be disposed of, synthetic leather, vinyl, medical waste, wood chips, small laboratory animals,
Incinerators are used to incinerate mixtures of A, B, S, resins, polymeric wastes, etc. on a daily basis, but they generate smoke, ash, strange odors, etc., and cause so-called pollution. Various methods have been devised, such as using a secondary burner, to achieve complete combustion in order to remove the oxidants, but they have the drawback of being expensive.

The present invention enables complete incineration by incorporating a blower into the furnace and forcing air (oxygen) injected from a nozzle. Next, the present invention will be specifically explained based on embodiments shown in the drawings.

1 is the main incinerator, 2 is the inlet, 3 is the primary combustion chamber, 4 is the secondary combustion chamber configured in a cylindrical shape, 5 is the cyclone,
6 is a passage from the primary combustion chamber (3) to the secondary combustion chamber (4), 7 is a passage from the secondary combustion chamber (4) to the cyclone (5), 8 is a blower, 9 (9□ ...98) is an air outlet 10 (10,...
...104) is an air outlet similarly provided in the middle part of the inner wall, 11 is an air outlet provided in the secondary combustion chamber (4), and 12 is a fireproof outlet that constitutes the inner wall of each combustion chamber. brick,
Refractory inorganic materials such as fine ceramics, 13 super refractory insulation material that covers the surroundings, 14 refractory cement that fills them and forms the main body, 15. 15' is a residue outlet, 16 is a cyclone (5 ) is a high-temperature air guide pipe provided in the center of the guide pipe 00, 17 is a box containing a flint prevention rock provided at one end of the guide pipe 00, 18 is a suction fan, and 19 is a motor.

Because of this configuration, materials to be incinerated are stored in the primary combustion chamber (
3) and operate the blower (8) at the same time as the ignition, air will be injected from each air outlet through the connected pipes (not shown). Outlets 9 (9I...98) intensify combustion in an agitated state by forcing air from each direction
．． (10, . . . 104) do not have opposing blow-off ports as shown in FIG. 3(b), so the high-temperature gas accompanying combustion is rotated at high speed counterclockwise in the figure along the inner wall. The fire gas then rotates horizontally at high speed inside the room and is sent to the secondary combustion chamber (4) through a passage (6) provided at the top, which is cylindrical in shape. Furthermore, the interior of the room is accelerated and forced to rotate horizontally by the air injected from the air outlet θυ provided on the passageway (6) side. As shown in Figure 2, this secondary combustion chamber (4) continues to rotate at this high speed for a while because the passage (7) to the cyclone (5) is provided near the bottom of the cylinder. It retains high heat and allows the entire flame to burn completely. While rotating at high speed, the temperature gradually decreases, that is, the specific gravity decreases, which is sent to the cyclone (5) through the passage (7) and completely combusted, thus completing the high-temperature treatment that also produces smoke, sparks, etc. The high-temperature air sent into the cyclone passes through the guide pipe α0 from the head and is sucked by the motor 0IIl by rotating the fan θη with a worm gear, which is connected to one end of the cyclone.
The air is discharged as clean air through a box 0η containing the anti-firestone particles j;. Fine ash and the like are collected at the bottom of the cyclone (5) and stored in the outlet at 15.15'.

In this way, it is advantageous to use metals such as Rosdol in the construction of the furnace. In addition, since the length of the blower (8) is sufficient, it has various effects such as being inexpensive and easy to operate.

In the figure, 20 is a blower room.

Claims (1)

[Claims] A cylindrical secondary combustion furnace is constructed in which the fire gas sent from the primary combustion furnace by forced air is rotated horizontally and horizontally at high speed to retain the high heat for a while, that is, to contain the heat and carbonize it.
