Abstract

(57) [Abstract] [PROBLEMS] To provide an incinerator that protects ducts from high temperatures, does not interfere with the input of incineration materials and the removal of ash, and does not complicate the processing of discharge ports, etc. A duct 6 for supplying air to 1 is installed inside the furnace wall so as not to disturb the input of incineration materials and the removal of ash, and is protected from high temperature by a water jacket 9. Further, if necessary, the water jacket portion of the furnace wall is partially replaced with the air jacket 12 so that the air can be discharged into the furnace chamber 1 from the hole formed in the inner wall of the air jacket 12 portion. .

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to an incinerator that incinerates general waste, medical waste, industrial waste, and the like, and more specifically to the structure of an incinerator devised to facilitate the supply of combustion air. .

[0002]

[Prior art]

 In a conventional water-cooled incinerator, if an air duct for supplying air to the furnace chamber is installed in the furnace chamber, the air duct will be deformed due to high temperature, and when the incinerator is thrown in and ash is removed, the air duct However, it has the drawback of being bulky and disturbing. Further, when the discharge duct is provided in the water jacket, it is necessary to install a large number of nozzles, which complicates the processing and takes time, resulting in a problem in terms of cost.

[0003]

[Problems to be solved by the device]

 This invention was made in order to eliminate the drawbacks described in the prior art.It protects the air duct from high temperatures, does not interfere with the input of incinerated materials and the removal of ash, and the processing of the discharge port etc. The purpose is to provide an incinerator that does not become complicated.

[0004]

[Means for Solving the Problems]

 (1) A discharge port for discharging air into the furnace chamber is provided at an appropriate position on the furnace wall. (2) Surround the air discharge duct installed in the furnace wall with water, air, heat-resistant material, or heat storage material. (3) The water jacket part of the furnace wall is partially replaced by an air jacket, and the air jacket part is provided with an air discharge port.

[0005]

[Embodiment of device]

 An example of an embodiment of the present invention will be described. In a normal water-cooled incinerator, an air discharge duct 2 is installed in a furnace chamber 1 as shown in FIG. 1, and a blower 3 installed outside is installed. Although air is sent into the furnace chamber 1 from the inside, in the present application, as shown in FIG. 2, a hole 5 is directly bored in the inner wall 4, and the duct 6 is attached to the inner wall 4 by surrounding the hole 5. wear. If the holes 5 are angled, the air flow discharged into the furnace chamber 1 can be changed to a spiral shape. The duct 6 may be attached by either a flange method or a fixing method such as welding. Reference numeral 7 is an outer wall, 8 is a blower pipe connecting the external blower 3 and the duct 6, and 9 is a water jacket. In this case, the duct 6 for discharging the air is protected by the water jacket 9, and the air is blown directly into the furnace chamber 1 through the hole 5 formed in the inner wall 4. Although not shown, the duct 6 may be protected by surrounding it with a heat resistant material such as glass fiber, ceramic fiber, clay, or a heat storage material.

Further, as shown in FIG. 3, a plurality of through holes 10 are formed outside the holes 5 formed in the inner wall 4 so that the air can be dispersed and discharged in multiple directions and curved. The metal fitting 11 may be attached. The sectional shape of the duct 6 is not limited, and various shapes such as corners, circles, and semicircles can be applied.

Further, as shown in FIG. 4, the water jacket 9 portion of the furnace wall is partially replaced with an air jacket 12 portion, and the hole 5 is formed in this air jacket 12 portion. Air is supplied to the air jacket 12 from the external blower 3 through the blower pipe 8. It is preferable that the water jacket 9 part and the air jacket 12 part are divided into blocks, respectively, so that they can be freely assembled by flanges, pins, bolts or the like because the degree of freedom increases.

[0008]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. (1) The air duct is protected by a water jacket, etc., and does not project into the furnace chamber as in the past, so it is deformed by high temperatures and interferes with the input of combustion products and the removal of ash. Never. (2) Since the holes are directly bored in the inner wall, it is not necessary to attach a large number of nozzles as in the conventional case, so that the processing is not complicated. (3) Since the amount of air supplied to the furnace chamber increases, unburned gas and unburned gas are easily burned. Depending on the conditions, burner burners for burning unburned gas and unburned gas, etc. Since it can be omitted, the equipment cost can be significantly reduced. (4) Since this air supply device has a simple structure, it can be mass-produced relatively inexpensively. This device has the above-mentioned effects, and its industrial utility value is high.
