Problems solved by technology

[0008] The object of the present invention is to propose a split-type multi-stage drum fermentation reactor for the problems of reduced filling rate, low utilization rate of effective volume, and large floor space occupied by traditional horizontal fermentation drums. It has the advantages of easy installation and debugging, saving motor energy consumption, and small equipment footprint. It can be widely used in the fermentation and composting of food waste, municipal solid waste, poultry manure, activated sludge and other solid wastes containing a large amount of organic matter. Drying

Embodiment 1

[0048] This embodiment discloses a split-type multi-stage drum fermentation reactor, which belongs to the field of organic solid waste treatment.

[0049] The structure of the split type multi-stage drum fermentation reactor is as follows figure 1 As shown, it includes a feeding device 1, a drum 3 and an air intake system 5 arranged in sequence, and the feeding device 1 includes but is not limited to a screw conveying device; the feeding device 1 is connected to the feed end of the drum 3, connected A feed end seal 2 is provided at the feed end seal 2, and an air outlet is provided on the feed end seal 2; the discharge end of the drum 3 is connected to the air intake system 5, and a discharge end seal 4 is provided at the connection. The bottom end of the discharge end seal 4 is provided with a funnel-shaped outlet, and the funnel-shaped outlet is lower than the level of the drum 3 .

[0050] The drum 3 includes four consecutively connected cylinders: a first cylinder 31, a ...

Embodiment 2

[0059] This embodiment discloses a split-type multi-stage 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 segments of cylinders connected in sequence, which are respectively: Material section cylinder body, middle temperature section cylinder body, high temperature section cylinder body, cooling section cylinder body and discharge section cylinder body.

[0060] According to the fermentation reaction stage of the material, the speed of each cylinder is controlled separately. The fermentation reaction stage of the material is divided into the feeding stage, the medium temperature reaction stage, the high temperature reaction stage, the cooling reaction stage and the discharging stage from the feeding to the discharging, corresponding to the feeding section of the cylinder, the medium temperature section of the cylinder, High temperature section cylinder body, cooling...

Abstract

The invention provides a split-type multi-stage drum fermentation reactor and a fermentation method. The split-type multi-stage drum fermentation reactor includes a feeding device, a drum and an air intake system arranged in sequence, and the feeding device and the drum feed end connection, the connection is provided with a feed end seal; the discharge end of the drum is connected to the air intake system, and the connection is provided with a discharge end seal; the drum includes multiple sections of cylinders connected in sequence, and the adjacent cylinders There is an intermediate sealing device at the joint of the cylinder body, and a support wheel support and a driving device are provided under each section of the cylinder body. The center line of the cylinder body forms an inclination angle of <1° with the ground. point, the discharge end is at the lowest point. The reactor of the present invention has the advantages of simple installation and debugging, saving motor energy consumption, and small equipment footprint, and can be widely used in solid waste containing a large amount of organic matter, such as kitchen waste, urban domestic waste, poultry manure, activated sludge, etc. Fermentation composting or biological drying treatment.

Description

technical field [0001] The invention relates to fermentation reactor technology, in particular to a split-type multi-stage 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 outskirts o...
