In the modern society, the recurring livelihood waste and the industrial waste formed by the industrial manufacturing process have gradually increased with the economic activity, so how to effectively dispose of waste has become an important issue for the relevant authorities. Question. Although the landfill method of landfill is most commonly used, it is difficult to obtain a suitable landfill landfill under the very limited land resources. In particular, the general landfill will still have doubts about the secondary pollution caused by the groundwater source. Therefore, the general public is quite resistant to any landfill near the residence.

Therefore, in order to solve the problem of waste, it is an appropriate option to have a high-efficiency incinerator that uses a small land area, is easy to set up, and can greatly reduce the amount of waste. Furthermore, the incinerator can generate additional heat energy that can be heated to produce warm water for use in a heated swimming pool or to warm the room in winter, or to generate electricity for further generation. The incinerator needs to continuously feed air to provide the oxygen required to burn the waste, and the waste burned in the fluidized bed incinerator is usually a floating type configured to form a fluidized bed with the input air, which can increase combustion. Efficiency, in which a fluidized gas diffusion mechanism for uniformly introducing air into an incinerator is an important operating device.

In the above-mentioned conventional technology, the fluidized diffusing mechanism that is currently used in the market is a wind deflecting plate type.

The cold slag pipe 4 and the hood 5, and the main function is to pass the air of the primary fan through the passage of the wind chamber 1 located at the lower part of the air distribution plate 2 through the bottom of the hood 5, and the small holes arranged in the upper part of the hood 5 flow out. The small hole of the hood 5 can spray a high-speed airflow and enter the bottom of the bed to blow the particles at the bottom, thereby establishing a fluidized working body. In addition, in order to exclude deposits in the bed material The slag that is laid down will arrange the slag port 4 in place.

However, the above-mentioned conventional technology has disadvantages in that, when incinerating different wastes, such as sludge having a high moisture content, commercial waste, or waste having a large fluctuation in calorific value, this type of diffusing device is likely to generate cold dregs. The tube 4 is clogged and cannot discharge the large slag or waste deposited in the area of the air distribution plate 2 in time, thereby affecting the operation of fluidization and the fluctuation of the furnace temperature.

Therefore, there is a great need for an innovative air duct type fluidized air diffusing mechanism that utilizes a small hole that is disposed at a proper angle with a horizontal inclination on the hood, that is, the inside of the small hole is inclined outward, so that the small hole can be Smoothly outputting the air from the air duct to generate the airflow required for fluidization can avoid clogging and increase the overall combustion efficiency, thereby solving the problems of the above-mentioned conventional technology.

The main purpose of the present invention is to provide a ducted fluidized diffusing mechanism, including a fluidized air distributor, at least one air duct, a plurality of hoods and a furnace body, which are disposed in an incinerator for providing fluidized dispersion. The function of the gas is beneficial to the full combustion of the bed material and waste in the incinerator, and greatly improves the operation efficiency. The air duct and the hood are arranged in the furnace body, and the hood is arranged on the corresponding air duct. And the fluidized air distributor and the air duct can be a hollow tube body.

A fluidized air distributor is coupled to the furnace body for delivering preheated or non-preheated air to the air duct of the furnace body. The air duct is located in the furnace body and connected to the fluidized air distributor for receiving the air of the fluidized air distributor, and further transmitted to the hood to form an air flow in the furnace body, providing bed material above the air duct, and discarding The source of oxygen required for the material.

In particular, the hood includes a plurality of small holes distributed around the lateral direction of the hood and configured to be horizontally inclined at an appropriate angle, that is, the inside of the small holes is inclined outwardly so as to be input from the fluidizing air distributor. The airflow can be evenly and densely distributed in the furnace body so that the waste above the air duct can be fully burned.

Therefore, the air duct type fluidized air diffusing mechanism of the present invention can be configured by using a small hole which is horizontally inclined at an appropriate angle on the hood, that is, the inside of the small hole is inclined outward, so that the small hole can be smoothly output. The air from the air duct creates the airflow required for fluidization, avoids clogging, increases the overall combustion efficiency, and solves the problem of reducing or eliminating incineration of different wastes, such as sludge with high moisture content, commercial waste, When waste solvents or wastes with large fluctuations in calorific value occur, it may happen that the cold slag pipe is blocked and the bulk slag or waste deposited in the air distribution plate area cannot be discharged in time.
