Embodiment 1

[0056] This embodiment discloses a split-type multi-stage ventilated drum fermentation reactor, which belongs to the field of organic solid waste treatment.

[0057]The structure of the split type multi-stage ventilated drum fermentation reactor is as follows figure 1 with figure 2 As shown, it includes a feeding device 1, a drum 3 and an air intake system 5. The feeding device 1 includes but is not limited to screw conveying equipment; the feeding device 1 is connected to the feeding end of the drum 3, and the connection is provided with a The feed end seal 2, the feed end seal 2 is provided with an air outlet; the air intake system 5 includes a main pipeline and 3 branch pipelines communicated with the main pipeline, and the 3 branch pipelines are respectively connected to the three sections of the barrel The end close to the discharge end is connected to supplement air for the multi-section cylinder respectively, and the discharge end of the drum 3 is connected to the ai...

Embodiment 2

[0068] This embodiment discloses a split-type multi-stage ventilated drum fermentation reactor, the structure of which is basically the same as that of Embodiment 1. The difference is that the drum 3 in this embodiment includes 5 sequentially connected cylinders, which are respectively: The cylinder body of the feeding section, the cylinder body of the middle temperature section, the cylinder body of the high temperature section, the cylinder body of the cooling section and the cylinder body of the discharge section.

[0069] The fermentation method carried out by using the above-mentioned split-type multi-stage ventilated drum fermentation reactor includes the following steps: the material enters the drum from the feed end through the feeding device, the material advances along the axis direction with the rotation of the drum, and the air flows from the discharge sealing device The air inlet on the top enters the inside of the drum, and the air contacts the material countercur...

Abstract

The invention provides a split-type multi-stage ventilated drum fermentation reactor and a fermentation method. The reactor includes a feeding device, a drum and an air intake system. The feeding device is connected to the feeding end of the drum, and the connection is provided with a feed end seal; The drum consists of multiple sections of cylinders connected in sequence. Intermediate sealing devices are provided at the joints of adjacent cylinders. Supporting rollers and driving devices are provided under each section of the cylinders. The centerline of the cylinders is at an angle of <1° to the ground. The inclination angle, the feed end of the drum is at the high point, and the discharge end is at the low point. The air intake system includes the main pipeline and multiple branch pipelines connected with the main pipeline. The connection with the air intake system is provided with a discharge end seal. The invention has the advantages of simple installation and debugging, saving motor energy consumption, small area occupied by equipment, and reasonable air supply, and can be widely used in fermentation composting or biological drying treatment of various solid wastes containing a large amount of organic matter.

Description

technical field [0001] The invention relates to fermentation reactor technology, in particular to a split-type multi-stage ventilated drum fermentation reactor and a fermentation method. Background technique [0002] Solid waste refers to solid, semi-solid, and gaseous objects, substances, and legal and administrative wastes generated in production, living and other activities that have lost their original use value or have not lost their use value but are discarded or abandoned. Articles and substances that are included in solid waste management according to laws and regulations. Unlike waste gas and waste water, solid waste migrates and spreads everywhere, and must occupy a large amount of land. The phenomenon of urban solid waste encroaching on land is becoming more and more serious. There are 6 billion tons of industrial solid waste and 500 million tons of domestic garbage accumulated in my country. 10 million tons of solid waste cannot be treated and is piled up on the ...
