Abstract

(57) [Summary] [PROBLEMS] By installing a windshield hood having a diameter larger than that of a smoke exhaust port of an incinerator, it is possible to keep the combustion temperature in the furnace properly without smoke burning even in a strong wind. SOLUTION: A cylindrical windbreak hood having a larger diameter is attached to the tip of a chimney of an incinerator to cover the area around the smoke outlet of the chimney, and at least the lower part of the windshield hood is opened. The end of the chimney is formed to have a diameter larger than that of the main body of the chimney, and the upper part of the chimney is opened to form the exhaust port, and the upper part of the windshield hood is closed. The end of the chimney is formed to have a diameter larger than that of the chimney main body, the upper part of the chimney is closed, the chimney outlet composed of a number of small holes is formed around the chimney, and the upper part of the windshield hood is opened.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a smoke exhaust device of an incinerator.

[0002]

[Prior art]

 FIG. 8 shows a normal chimney in which the diameter of the main body 1A and the tip 1B of the chimney of the incinerator does not change. 9 and 10 show a conventional example in which the tip 1B of the chimney of the incinerator is formed to have a diameter larger than that of the chimney main body 1A. 8 and 9 show an example in which the upper portion of the chimney is opened to form a smoke outlet 3, and FIG. 10 shows a case where the upper portion 6 of the chimney is closed and the peripheral surface 7 of the tip 1B is formed from a number of small holes such as a wire mesh or punched metal. It was formed in the smoke outlet. In FIGS. 9 and 10 of the conventional example, the tip 1B of the chimney is formed to have a larger diameter than the chimney main body 1A, so that the smoke discharged from the chimney tip can be easily discharged. However, in these conventional examples, when the wind is strong, the fast air flow sucks out more smoke than necessary from the exhaust port, so extra outside air flows into the incinerator and the combustion temperature inside the furnace decreases, and Sometimes it was completely burned.

[0003]

[Problems to be solved by the invention]

 The present invention solves such a conventional problem, and aims to prevent smoke discharged from a chimney outlet from being affected by wind even in a strong wind.

[0004]

[Means for Solving the Problems]

 In order to achieve this object, the invention of claim 1 is to attach a cylindrical windbreak hood having a larger diameter to the end of the chimney of the incinerator to cover the area around the smoke outlet of the chimney and to use the windshield hood. At least the lower part is open. The invention according to claim 2 is characterized in that the chimney tip is formed to have a diameter larger than the chimney main body, and the chimney upper portion is opened to form the smoke outlet, and the windshield hood is closed. Features. According to a third aspect of the present invention, the tip of the chimney is formed to have a larger diameter than the main body of the chimney, the upper part of the chimney is closed, and the chimney outlet composed of a number of small holes is formed on the peripheral surface thereof. Then, the upper part of the windshield hood is opened.

[0005]

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is an overall view of the incinerator of the first example or the second example. FIGS. 2 and 3 show a first example in which a chimney 1 having a normal shape is fitted with a cylindrical windshield hood 2 having a larger diameter than the chimney 1 to cover the periphery of a smoke outlet 3 of the chimney. The windshield hood 2 opens the lower part 4. When the area around the smoke outlet 3 is covered with the windshield hood 2 with the upper part 5 closed, even in the case of strong wind, the smoke is not sucked out from the smoke outlet and burned up due to the fast air flow.

FIGS. 4 and 5 show a second example in which the end portion 1B of the chimney 1 is formed to have a diameter larger than that of the chimney main body portion 1A. The upper part 5 of 2 is closed. Since the upper part 5 of the windshield hood 2 is closed, the smoke passes through the windshield hood 2 and is discharged to the lower outlet 4 and is not affected by the strong wind at all. There is no danger of inhaling more air than necessary, and the combustion temperature in the furnace is maintained appropriately. FIGS. 6 and 7 show a third example in which the tip 1B of the chimney 1 is formed to have a diameter larger than that of the chimney main body 1A and the upper part 6 is closed. A smoke outlet 7 composed of small holes is formed. The upper part 8 of the windshield hood 2 is opened. Since the upper part of the chimney 6 is closed, it is convenient that rain does not directly enter the chimney 1. In the case of this embodiment, the smoke outlet 7 of the chimney is formed of a gas permeable steel plate such as a net or perforated metal. The incinerator F, chimney 1, windbreak hood 2, and chimney upper 6 are all made of SS (rolled steel for general structure) or SUS (stainless steel). The connection of the incinerator F, the chimney 1, the windshield hood 2, the upper part 6 of the chimney, etc. may be made by either welding or bolt-nut connection.

[Effect of the invention]

 According to the invention of claim 1, a cylindrical windscreen hood 2 having a larger diameter is attached to the tip 1B of the chimney of the incinerator to cover the periphery of the smoke outlet 3 of the chimney, and the lower part 4 of the windscreen hood 2 is provided. The simple installation structure that opens the air does not prevent the smoke from being sucked out from the smoke outlet by the fast air flow in the strong wind and burning. Since the incinerator does not draw more outside air than necessary, it has the effect of not lowering the combustion temperature inside the furnace and generating black smoke due to incomplete combustion. The invention of claim 2 has a structure in which the tip 1B of the chimney 1 is formed to have a larger diameter than the chimney main body 1A, the upper part of the chimney is opened to serve as a smoke outlet 3, and the upper part 5 of the windshield hood 2 is closed. Smoke passes through the windshield hood 2 with the upper part 5 completely closed, and is discharged to the lower outlet 4, and is not affected by the strong wind at all. Therefore, the smoke burns up and unnecessarily outside air enters the incinerator. There is no danger of inhaling, and the combustion temperature in the furnace is maintained properly. The invention according to claim 3 is that the upper part 6 of the chimney 1 at the tip 1B of the chimney 1 is closed, the chimney 7 composed of a number of small holes is formed on the peripheral surface, and the upper part 8 of the windshield hood 2 is opened. The structure ensures that rain does not directly enter the chimney 1 and that there is no danger of smoke burning up in the event of strong winds and inhaling unnecessary outside air into the furnace, and that the combustion temperature inside the furnace is maintained appropriately. Has an effect.
