Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] see figure 1 , and combined with figure 2 As shown, a biological fermentation and drying system for organic solid waste in the present invention includes a drum 10 and an induced draft fan 20. The two ends of the drum 10 are respectively provided with a feed port 11 and a discharge port 12, and the drum 10 is horizontal. Set and the bottom is provided with a support roller, the drum 10 is driven by a motor 15 to drive it to rotate, the inner surface of the drum 10 is provided with a spiral drain plate 13, and a plurality of stirring plates are installed on the drain plate 13 at intervals. Rod, the feed port 11 of the drum 10 is externally connected to the return ...

Abstract

The invention discloses an organic solid waste biological fermentation drying system; a drum-type sealing structure is adopted, after organic solid waste is input into a drum through a feeding port, the drum is driven by the motor to rotate, and the organic solid waste is transferred from one side of the feeding port to one side of a discharging port under the action of a drainage plate in the drum; and meanwhile, in the transferring process, due to the effect of a stirring rod, air guided in by an induced draft fan can be fully mixed with the organic solid waste, so that aerobic fermentationof the organic solid waste is guaranteed, the whole process is carried out in a sealed mode, no waste gas or waste water is generated, and treatment of the organic solid waste is more environmentallyfriendly; because of the combination of a return air pipe with a dehumidification unit and a heat pump unit, excessive heat generated by high-temperature aerobic fermentation can be recycled, and theenergy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of organic solid waste treatment such as sludge or kitchen waste, and more specifically relates to a biological fermentation and drying system for organic solid waste. Background technique [0002] At present, the dry weight of sludge discharged by my country's sewage treatment plants is about 1.4 million tons per year, and it is increasing at a rate of more than 10% every year; moreover, the sludge contains a large amount of harmful substances such as heavy metals and pathogenic bacteria, which is harmful to the environment; It can be seen that the problem of environmental pollution caused by sludge has become increasingly prominent, causing greater safety hazards, environmental hazards and economic burdens to the society. [0003] The market demand for solid waste treatment such as sludge or kitchen waste is huge, especially in recent years for the joint centralized treatment of municipal sludge, kitchen wa...
