Description

[Detailed description of the device]

[Industrial field of application] [0001] The present invention will not cause a safe pollution without using both types of incinerators of the construction type or the water-cooled type due to the diversification of discarded waste. It has become difficult to incinerate. It aims to incinerate diversified waste safely and at low cost with a single incinerator.

[Prior Art] Conventionally, depending on the type and properties of waste, high-molecular-weight high-calorie waste is supplied to the furnace by installing a large number of air nozzles in the furnace in a water-cooled jacket type incinerator. Using a water-cooled jacket type incinerator that achieves complete combustion, low calorie waste with a high water content is incinerated by attaching an auxiliary combustion burner to a furnace type incinerator with good heat storage properties, and the exhaust gas is further subjected to secondary combustion. An incinerator with a structure that does not cause pollution by reburning with a burner is used in the room. Therefore, with the diversification of waste, it is becoming impossible to cope without installing different types of incinerators at one business site.

[Problems to be Solved by the Invention] In the conventional technology, the incineration of a wide variety of wastes that require a plurality of incinerators is to incinerate efficiently and safely with one incinerator. is there.

[Means for Solving the Problems] For low-calorie waste, a furnace-building incinerator having heat buildability is used as a reverse-burning type incinerator that reverses normal upward combustion, and flue gas is discharged from a flue. Therefore, the exhaust gas containing a large amount of unburned gas generated from the built-in reverse combustion type incinerator, which was made to flow into the combustion zone of the water-cooled jacket type incinerator exclusively for high-calorie, was secondary in the water-cooled jacket type incinerator. The structure is such that a complete combustion is achieved by the sufficient supply of combustion air and the heat of incineration of high-calorie waste.Therefore, in the conventional incinerator incinerator, the incineration of high-calorie waste such as polymer is a smoke pollution. Although it was not possible to incinerate, due to the effect of the combined type incinerator, it is possible to incinerate mixed low-calorie and high-calorie waste in the built-up reverse combustion type incinerator, so the fuel for reburning for auxiliary combustion is greatly cut. it can.

In the water-cooled jacket type incinerator, it is necessary to increase the attractiveness of combustion exhaust gas in order to be able to incinerate high-calorie wastes such as polymer even during the operation of the built-in reverse combustion type incinerator. is there. It is also important to install a dust collector to prevent the scattering of dust. In the conventional method, an axial-flow reversal type cyclone was installed and, in some cases, an induced blower was required, but in the present invention, in order to solve this problem, an axial-flow orthogonal type is installed between the water-cooled jacket type incinerator and the chimney. By installing an axial flow orthogonal type ejector cyclone with an ejector device incorporated in the cyclone, it is possible to improve the simultaneous operation and dust collection efficiency of both furnaces.

[0006] The axial flow orthogonal type cyclone has an ejector function to solve the dust collecting function and the attraction function, and the axial flow orthogonal type ejector cyclone is installed between the furnace body and the flue to provide a universal system. The installation area of the incinerator can be made large enough to be installed within the installation area of a conventional furnace-type incinerator.

[Advantages of the Invention] With respect to a wide variety of wastes that cannot be incinerated without using a plurality of incinerators in the conventional technology, the universal system incinerator of the present invention is a composite body incorporating a reverse combustion structure. It is possible to incinerate all the wastes at low cost by taking advantage of the above.

[0008] The present invention is intended to reduce waste with different properties for low-calorie by connecting a furnace-type and a water-cooled jacket-type incinerator, which incinerate wastes with completely different properties as described above, by a reverse combustion method. Since mixed combustion is possible in the furnace-building reverse combustion type incinerator without a re-combustion chamber, a large amount of auxiliary combustion fuel can be cut.

The installation area was on the expansion side due to the incinerator of the complex, but by incorporating the ejector function in the axial flow orthogonal cyclone, the universal system incinerator can be installed within the installation area considered in the conventional furnace. .

The sizes of both furnaces can be freely combined in accordance with the property and amount of waste discharged in the installation plan. Therefore, it is possible to assemble an incinerator suitable for the amount of waste materials as a system, so there is no waste in the construction of the device.
