Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an incinerator suitable as a refuse incinerator for general households and a refuse incinerator in a refuse disposal site.

[0002]

[Prior art]

 Many incinerators in use today, regardless of whether they are vertical or horizontal, injecting air or oxygen into the incinerator to increase the speed of burning incombustible waste.

[0003]

[Problems to be solved by the device]

 Since the above-mentioned conventional technology only ejects air and oxygen straightly into the furnace, the unburned gas stays in the furnace for a short period of time and harmful gases are released into the atmosphere. As a result, there was a problem in that the effects of secondary heat utilization such as smoke pollution and hot water supply and heating were quite low.

In order to eliminate the above-mentioned problems, the present invention generates whirlwind in the furnace during combustion, thereby extending the residence time of unburned gas in the furnace and achieving complete combustion without environmental pollution. The goal is to get as close as possible.

[0005]

[Means for Solving the Problems]

 The object of the present invention described above is to construct an incinerator that combusts an incinerator while feeding air into the furnace body. In addition to being erected in communication with each other, a plurality of fumaroles are arranged on the peripheral surface in the middle portion of the sending cylinder in an orderly manner, and rectifying fins are provided on the outer side thereof so as to extend substantially tangentially to the sending cylinder. Was achieved in.

In addition, a plurality of fumaroles may be slanted in the tangential direction in the peripheral surface of the intermediate portion of the sending cylinder to form an incinerator in which the rectifying fins are omitted. Alternatively, a plurality of fumarole groups may be divided and provided in a transparent manner.

[0007]

[Action]

 Before and after ignition in the furnace, the air supply source is started, and if a large amount of air is sent into the furnace from a large number of fumaroles through the cylinders, the rectification is performed by bending it tangentially to the outside. Due to the rectifying action of the fins, the air emitted from many fumaroles rises while swirling from the center of the furnace along the inner peripheral surface.Therefore, in the high temperature furnace of harmful unburned gas emitted from the incinerated matter during combustion. The residence time can be extended by 3 to 4 times as compared with the conventional example by the straight blowing, and most of the harmful unburned gas is burned out in proportion to the extension time.

【Example】

 Examples will be described with reference to the drawings. First, as shown in FIGS. 1 and 2, the basic configuration of the present invention is to construct an incinerator that burns an incinerator while feeding air into the furnace body. A cast iron feed cylinder 2 with an upper end sealed height of about 40 cm and an inner diameter of about 8 cm is installed on the floor on the lower plate 1a of the furnace body 1 made of heat-resistant material and having an inner diameter of about 0.8 m and a height of about 2 m. The air supply source P such as the sirocco fan blower is erected so as to communicate with the pipe Pa and the air chamber Pb. As the upright means, as shown in FIG. 1, a female threaded ring bolt 2b is used for screwing.

As shown in FIG. 2, about 20 fumaroles 3, 3 having a diameter of about 2 to 4 mm are regularly provided on the peripheral surface in the middle of the feeding cylinder 2 at regular intervals, and the feeding holes on the outside thereof are provided. The incinerator according to the present invention can be constructed by arranging a large number of rectifying fins 4, 4 extending substantially tangentially to the air cylinder 2 by means such as welding as shown in FIGS. 2 and 3.

In FIG. 1, the reference numeral 2a indicates a sealing lid that covers the upper end of the feed cylinder 2, the reference numeral 1b indicates a chimney, and the portions indicated by reference numerals 5a and 5b in FIG. An inlet (not shown) and an outlet for ash and burnt residue are closed by an opening / closing lid 5c as shown in FIG. 5 after ignition of the material to be burned.

Before and after this ignition, the air supply source P is started, and if a large amount of air is sent into the furnace from the large number of fumarole holes 3 and 3 via the air supply cylinder 2, the air is tangentially curved outward. Due to the rectifying action of the rectifying fins 4 and 4 which are arranged so as to be inclined, the air discharged from the large number of fumaroles 3 and 3 extends from the center of the furnace to the inner peripheral surface as shown in FIGS. Since the temperature rises slowly while swirling, the residence time of harmful unburned gas emitted from the incinerated material during combustion in the high temperature furnace can be extended by 3 to 4 times as compared with the conventional example by straight blowing. Most of the harmful unburned gas was burned out in time for the extension, and the environmental pollution problems such as air pollution and bad smell pollution could be solved. In addition, the combustion efficiency naturally increased, the heating cost was reduced, and the amount of residual ash was significantly reduced.

Further, according to the present invention, as shown in FIG. 7, if a plurality of fumaroles 3 and 3 are tangentially slanted on the peripheral surface of the intermediate portion of the feed cylinder 2, the rectifying filter on the outside thereof is provided. Is unnecessary.

In addition, as shown in FIG. 8, when a large number of unit feeding cylinders 2 are vertically connected in series by female screw rings 2c and air is blown from the fumaroles 3 of each feeding cylinder 2 at once, In particular, whirlwind is generated evenly in the furnace, and by making the penetration direction of the uppermost fumarole group and the tilting direction of the rectifying fins opposite to those in other furnaces, the whirlwind in the upper part of the furnace is moderated. When cancelled, the smoke emitted from the chimney 1b and the swirling of the updraft can be softened.

[0014]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. The air discharged from the fumarole 3 of the delivery cylinder 2 gradually rises while swirling from the core along the inner peripheral surface due to the tangential inclination of the rectification fin 4 and the fumes 3 itself in the tangential direction of the delivery cylinder. The residence time of harmful unburned gas emitted from the incineration in the high temperature furnace can be extended by 3 to 4 times as compared with the conventional example by the above-mentioned straight blow, and the harmful unburned gas corresponding to this extension time can be extended. Most of them will be burned out, which has the first effect of being able to solve environmental pollution problems such as air pollution pollution, odor pollution and smoke pollution.

Moreover, since most of the conventional unburned gas is burned out, the combustion efficiency naturally increases, and the hot water supply and heating costs can be reduced, and the amount of residual ash can be significantly reduced. The second effect is that the maintenance management can be simplified.

According to the third and fourth aspects, since a large number of unit feeding cylinders 2 are vertically connected in series by the female screw ring 2c and the air is blown from the fumaroles 3 of each feeding cylinder 2 all at once, Whirl winds are generated evenly in the furnace, and the whirlwind in the upper part of the furnace can be canceled moderately by making the penetration direction of the uppermost fumarole group 3A and the inclination direction of the rectifying fins opposite to those of other ones. It is possible to soften the swirling of smoke and ascending airflow emitted from the chimney 1b, and it is possible to add the effect of preventing the rising of burning dust.
