Technical Field

[0001] The utility model relates to a U-shaped structure incinerator technology. Background Art

[0002] High-viscosity waste liquid is treated by incineration to remove toxic and harmful components. During the incineration operation, a corresponding incinerator is required. However, conventional incinerators have problems such as uneven incineration temperature, poor waste liquid atomization effect, short flue gas residence time, easy damage to the lining, and incomplete combustion, which affect the incineration effect of high-viscosity waste liquid.

[0003] Therefore, a U-shaped vertical high-viscosity waste liquid incinerator is urgently needed to fully burn the high-viscosity waste liquid. Utility Model Content

[0007] The waste liquid spray gun is a dual-fluid steam atomizing spray gun, which can achieve efficient atomization of high-viscosity waste liquid and avoid coking and burning of the gun tip.

[0008] The primary combustion-supporting air port is a strong swirl air duct with a louver structure, which can achieve high-intensity turbulent mixing of waste liquid and primary combustion-supporting air.

[0009] The combustion chamber adopts a cylinder made of refractory corundum bricks and heat-insulating materials, which can realize high-speed flow of flue gas, balanced flow field of the incinerator, and no dead corners for deposition of particulate matter in the incinerator.

[0010] The secondary combustion-supporting air port is an annular air duct, which can achieve efficient mixing of the combustion-supporting air and the combustible material while meeting the minimum oxygen content requirement of the incinerator.

[0011] The U-shaped combustion chamber is a cylinder with corundum castable, which can realize the discharge of particulate matter into the furnace and ensure the balance of the flow field of the incinerator.

[0012] The ash discharge port of the U-shaped combustion chamber is a plug with a lining, which can realize the discharge of particulate matter into the furnace and ensure the balance of the flow field of the incinerator.
