Abstract
The invention discloses a Teflon fluidized bed furnace, comprising a furnace shell and an air distribution plate, wherein the air distribution plate is located at the bottom of the furnace shell, the inner wall of the furnace shell is coated with a Teflon coating layer, one side wall of the furnace shell is provided with a furnace gas outlet, a secondary air inlet, an ignition opening and an overflowing opening, the other side wall of the furnace shell is provided with an ore inlet, and the bottom of the furnace shell is provided with a slag outlet. In such a manner, the inner wall of the Teflon fluidized bed furnace is coated with the Teflon coating layer to increase the smoothness of the fluidized bed furnace, so that coal ash generated by burning in the fluidized bed furnace is unlikely to remain on the wall of the fluidized bed furnace, and the fluidized bed furnace can keep clean conveniently and can be in a good working state for a long time.
Description
Technical field
The present invention relates to a kind of combustion furnace, particularly relate to a kind of fluidized bed furnace with Teflon coat.
Background technology
Fluidized bed furnace is a kind of coal-burning boiler, is one of developed recently a kind of new combustion technology of getting up.When fluid flows through the static shot-like particle bed of material from below to up, if flow velocity surpasses certain limit, bulk cargo layer starts to expand, wriggles and has mobility, becomes false fluid state, and this process is called the fluidisation of bulk cargo layer.Pellet after fluidisation stirs similar to the boiling of fluid up and down, therefore claim again boiling bed, by the Thermal Equipment of the method material handling, is called fluidized bed furnace.But common fluidized bed furnace is when fire coal, and long-term use has on the furnace wall that coal ash remains in fluidized bed furnace, cleaning difficulty, affect the efficiency of combustion of fluidized bed furnace, the serviceability of reduction fluidized bed furnace.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of Teflon fluidized bed furnace, this fluidized bed furnace has increased the smoothness of fluidized bed furnace by teflon coating on wall within it, make the coal ash after burning in fluidized bed furnace be not easy to remain on the furnace wall of fluidized bed furnace, be conducive to keep the clean of fluidized bed furnace, make fluidized bed furnace for a long time in good working order.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of Teflon fluidized bed furnace is provided, comprise: furnace shell and dispersion plate, described dispersion plate is positioned at the bottom of described furnace shell, on the inwall of described furnace shell, be coated with teflon coatings, on one side sidewall of described furnace shell, be provided with furnace gas export, auxiliary air import, lighting-up tuyere and overfall, on the opposite side sidewall of described furnace shell, be provided with ore entrance, the bottom of described furnace shell is provided with slag outlet.
In a preferred embodiment of the present invention, in described furnace shell, near described dispersion plate place, be provided with many cooling tubes.
In a preferred embodiment of the present invention, the top of described furnace shell is provided with explosionproof hole.
In a preferred embodiment of the present invention, the thickness of described Teflon coat is 0.2mm～0.3mm.
The invention has the beneficial effects as follows: Teflon fluidized bed furnace of the present invention has increased the smoothness of fluidized bed furnace by teflon coating on wall within it, make the coal ash after burning in fluidized bed furnace be not easy to remain on the furnace wall of fluidized bed furnace, be conducive to keep the clean of fluidized bed furnace, make fluidized bed furnace for a long time in good working order.
