NOVELTY - Special anaerobic reaction device, comprises a main body composed of a closed container, an oil and floating slag collecting hopper (1), an oil and floating slag discharging tube (2), a heating system (3), oblique lower agitating device (4), static liquid level meter (5), settled material collecting center, liquid discharge pipe and a methane collecting tube. The upper part of the container is provided with an oil and floating slag collecting hopper opening upwards, and the hopper body contracting downwards to a tube.    USE - Used as an anaerobic reaction device for food waste.    ADVANTAGE - The anaerobic reaction device discharges the upper accumulating oil and floating slag and the lower deposit settled material, thus does not lead to formation of deposits in the corners.    DETAILED DESCRIPTION - Special anaerobic reaction device for food waste, comprises a main body composed of a closed container, an oil and floating slag collecting hopper (1), an oil and floating slag discharging tube (2), a heating system (3), oblique lower agitating device (4), static liquid level meter (5), settled material collecting center, liquid discharge pipe and a methane collecting tube. The upper part of the container is provided with the oil and floating slag collecting hopper opening upwards, and the hopper body contracting downwards to a tube. The upper openings can be square or circular and on the same plane surface of the upper part of the container. The number of the oil and floating slag collecting hopper is determined according to the content of the oil and floating slag. The more the content of oil and floating slag, the more is the number of the oil and floating slag collecting hopper. The lower tube of the oil and floating slag collecting hopper is connected with the oil and floating slag discharging tube that is connected with the oil and floating slag collecting hopper in an obtuse angle, which passes through a container wall obliquely and extends out of the container. The lower part of the container is provided with a static liquid level meter. The lower part of the container is provided with an oblique lower agitating device, a motor of which is out of the container and an agitating paddle extends out of the container, and the direction is downwards obliquely. The bottom of the internal of the container is provided with a settled material collecting center that binds off downwards. The bind-off opening is connected to a slag discharge pipe. The container is internally provided with a heating system, the lower part of which is provided with a hot water inlet and the upper part is provided with a hot water outlet, which are distributed in the container evenly. The middle part of the container is provided with a liquid discharge pipe and the top of the container is provided with a methane collecting tube.
