Problems solved by technology

In order to prolong the residence time of fermented materials such as organic waste in the drum reactor to ensure the fermentation effect, the length of the drum is usually designed to be more than 10 times or even more than 20 times the diameter of the drum, so the floor area is still large and the equipment manufacturing cost is high
Drum-type aerobic fermentation reactor, due to the high power of the drum rotation; there is a necessary gap between the rotating drum and the fixed end cover to ensure relative movement, and the sealing is more difficult

Abstract

The invention discloses a horizontal aerobic fermentation reactor and an aerobic fermentation reaction method. The horizontal aerobic fermentation reactor comprises a horizontal cylinder, wherein a stirring device is arranged in the horizontal cylinder. Through a jacket connected with an external connecting pipe, a fermentation material is rapidly heated and an aerobic fermentation reaction is controlled to be carried out at a proper temperature, death and dormancy of aerobic microorganisms due to overhigh fermentation temperature are avoided; through driving the stirring device with a helical blade to rotate, the fermentation material is in full and uniform contact with oxygen to generate a high-speed aerobic reaction; through a ventilating flange connected with an external ventilating system, waste gas generated by the reaction is intensively treated and then exhausted; and heat generated by the reaction is recycled. The horizontal aerobic fermentation reactor has the advantages of small occupation area, lower drive power and good environmental protection and energy saving effect.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment, in particular to a horizontal aerobic fermentation reactor and an aerobic fermentation reaction method, which are widely used in the biological treatment of solid organic waste. Background technique [0002] Aerobic fermentation degrades organic matter through microorganisms, so that organic waste can be reduced, harmless, and resourced. At present, the widely used composting technology mainly has the disadvantages of large area, long fermentation time, and low fermentation speed in low temperature weather. Although the efficiency or effect of aerobic composting can be improved by means of forced ventilation, turning or stirring during composting , but the heat and odor generated by fermentation are discharged into the atmosphere, causing environmental pollution. The equipment-based Dano drum-type aerobic fermentation reactor has the characteristics of high fermentation efficiency...
