AI Technical Summary
In the long-term use of traditional high-heat recovery thermal incinerators, the accumulation of ash on the top of the incinerator forms thermal resistance, resulting in a reduction in heat transfer efficiency, thereby increasing fuel consumption and operating costs. The traditional cleaning method is more troublesome.
A cleaning mechanism including a heat insulation plate, an electromagnetic vibrator and an air jet port is designed. The high-frequency vibration of the heat insulation plate is driven by the electromagnetic vibrator, and the air flow blown in by the high-pressure air pump is sprayed out from the air jet port, directly impacting the heat receiving. The accumulation of dust on the surface prompts it to fall.
It realizes rapid and effective removal of ash on the top of the incinerator, improves heat transfer efficiency, reduces fuel consumption and operating costs, and observes the real-time status of the thermal insulation board through the visible window, ensuring the efficient operation of the incinerator.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of incinerators, in particular to a high-heat recovery heat storage incinerator. Background Art
[0002] The high heat recovery regenerative incinerator is a device used for the treatment of medium and high concentration organic waste gas. Its working principle is to oxidize the organic matter in the waste gas into corresponding carbon dioxide and water at high temperature, thereby purifying the waste gas and recovering the heat released when the waste gas decomposes. This equipment can achieve efficient heat recovery and waste gas purification.
[0003] During the long-term use of the existing high-heat recovery thermal incinerator, the flue gas generated by the combustion of waste during the combustion of materials contains a large amount of particulate matter, including incompletely burned organic matter, inorganic salts and metal oxides. These particulate matter rises with the flue gas, cools and settles on the top of the incinerator to form ash. However, as the ash accumulation continues to increase, a layer of thermal resistance will be formed on the heating surface of the incinerator, resulting in a decrease in heat transfer efficiency, which will increase the exhaust temperature of the incinerator and reduce the thermal efficiency, thereby increasing fuel consumption and operating costs. At this time, it is necessary to clean the ash accumulation regularly. The traditional cleaning method generally requires the incinerator to be shut down, and then manual drilling into the combustion chamber to scrape the top. This method is more troublesome. Therefore, when designing a high-heat recovery thermal incinerator, it is necessary to provide a novel cleaning mechanism that can clean the ash accumulation on the top of the incinerator more quickly and effectively, thereby improving the overall practicality. Utility Model Content

[0008] Furthermore, the heat insulation board is arranged in a semi-arc structure, and the material of the heat insulation board is ceramic fiberboard.
[0009] By adopting the above technical solution, since the insulation board is arranged in a semi-arc structure, the semi-arc insulation board design can better adapt to the heat flow distribution inside the incinerator, reduce the heat loss to the external environment through the furnace top, and this shape helps to reduce heat convection and heat radiation, thereby improving the insulation efficiency, helping to maintain the high temperature environment in the furnace and ensuring combustion efficiency.
[0010] Furthermore, a plurality of the jet ports are provided, and the plurality of the jet ports are arranged equidistantly in a circular array.
[0011] By adopting the above technical solution, multiple air jets can effectively knock down the dust attached to the insulation board.
[0012] Furthermore, the air jet is arranged obliquely, and the material of the air jet is a nickel-based alloy.
[0013] By adopting the above technical solution, since the air jet is arranged obliquely, the air jet can effectively blow onto the heat insulation board.
[0014] Furthermore, a visual window is provided on the outer surface of the upper furnace body, and the visual window is made of quartz glass.

[0018] Furthermore, the filtering furnace comprises a purification chamber, and a supporting frame is arranged at the bottom of the purification chamber.

[0026] In summary, the utility model mainly has the following beneficial effects:
[0027] 1. The utility model is provided with a cleaning mechanism. When dust is found to be attached to the heat insulation board, the electromagnetic vibrator can be started through the control console, and then the electromagnetic vibrator will drive the heat insulation board to vibrate at a high frequency. Then, the external high-pressure air pump can be started through the control console to introduce the high-pressure gas into the pneumatic pipe inside the mounting ring, and then the gas is ejected from the air jet port. Then, the gas will further blow the heat insulation board to cause the dust to fall off. Through the above operation, the high-frequency and low-amplitude vibration generated by the electromagnetic vibrator causes cracks in the dust layer on the heating surface at the top of the incinerator and gradually loosens it, which helps to destroy the adhesion between the dust and the heating surface, making the dust easier to fall off. The high-pressure airflow ejected through the air jet port can directly impact the dust on the heating surface, causing the dust to fall off, thereby achieving the purpose of quickly removing the dust.
[0028] 2. The utility model provides a visual window through which the dust accumulation of the insulation board can be visually seen. Since the visual window is made of quartz glass, the visual window has extremely high high temperature resistance and can withstand the high temperature environment generated inside the incinerator. This makes quartz glass an ideal material for the visual window of the incinerator, which can maintain stable physical and chemical properties at high temperatures. In addition, the visual window has good transparency, so the combustion situation inside the incinerator can be clearly observed. BRIEF DESCRIPTION OF THE DRAWINGS
