Special equipment for rubbish fermentation and rubbish fermentation method

Abstract

The invention discloses a special device for waste fermentation, which comprises a fermentation cylinder (2) connected with a driving mechanism (4); wherein, the fermentation cylinder (2) is rotationally connected with a riding wheel frame component (3); the fermentation cylinder (2) is respectively provided with a feed inlet (21), a discharging hole (23), an air inlet (24) and an air outlet (22); a copy board (11) and a baffle (12) are arranged in the fermentation cylinder (2), and the baffle (12) is provided with at least one via hole aperture of which can be adjusted the. A waste fermentation method by utilizing the device is also provided by the invention, the fermentation cylinder (2) with an inner cavity which is 32 meters in length and 3.2 meters in diameter is selected, the rotational speed of the fermentation cylinder (2) is controlled to be 2r / min, and the angle between the central axis of the fermentation cylinder (2) and the horizontal plane of the fermentation cylinder (2) is 2 degrees; heated air is input from the air inlet (24) and the ventilation rate is 10000m<3> / h. Treating wastes by the device of the invention ensures that the waste fermentation period is shorter and the fermentation is more full.

Description

technical field [0001] The invention relates to a garbage fermentation device and a fermentation method, in particular to a dynamic aerobic fast biological fermenter and a corresponding fermentation method. Background technique [0002] Dano drum is a horizontal fermentation device for dynamic aerobic fermentation of garbage. The drum is made of steel plate, the diameter is generally 3-4m, the length is 30-40m, and the length-to-diameter ratio is 7-10; in actual work, the drum and the ground maintain a slight inclination angle (the feed end is high, the discharge end is low), It is convenient for the material to move from the feed port to the discharge port under the action of gravity; the drum is also provided with an air inlet and an air outlet accordingly. The drum is driven to rotate by the driving mechanism; the drum is supported by three sets of supporting wheel frame components, and there are three sets of outer ring gears corresponding to the supporting wheel frame ...

AI Technical Summary

Problems solved by technology

[0009] 1. Since the waste in our country is not classified, and the composition of the waste in different regions and seasons varies greatly; while the flow in the Dano drum is fixed and cannot be adjusted; therefore, the Dano drum cannot achieve the general purpose

Only by changing the shape of the baffle according to the needs, several Dano drums with specific flow can be designed; this will lead to an increase in cost and is not easy to use

[0010] 2. Due to the large temperature changes in different seasons, especially in winter, relying on the heat generated by the fermentation itself and the heat generated by the friction between the material and the inner surface of the cylinder and the baffle is not enough to maintain the necessary temperature for fermentation; and it also leads to The temperature fluctuates greatly, so it will eventually lead to the instability of the fermentation of garbage with different components in different seasons
