Crawler-type multilayer continuous aerobic fermentation tank equipment and technology

Abstract

The invention relates to crawler-type multilayer continuous aerobic fermentation tank equipment and a technology. The equipment comprises multiple layers of crawler-type continuous aerobic fermentation tanks which are overlapped up and down, wherein the crawler-type continuous aerobic fermentation tanks of adjacent layers are arranged along opposite directions and have opposite conveying directions; crawler conveying mechanisms and feeding ports are arranged on the bottom of the crawler-type continuous aerobic fermentation tanks, wherein the crawler conveying mechanisms are arranged aside thefeeding ports, and the feeding ports of the adjacent layers are oppositely arranged on the two sides of the crawler-type continuous aerobic fermentation tanks; and forcing oxygen-filling pipelines arearranged in the middle of the crawler-type continuous aerobic fermentation tanks. According to the invention, mixed materials are alternately conveyed and fermented in multiple layers of crawler-typecontinuous aerobic fermentation tanks; upper and lower layers of materials fall into a space between the crawler-type continuous aerobic fermentation tanks, and materials are naturally filled with oxygen, so that the fermentation process can be realized; the period is short; less space is occupied; the energy consumption is reduced; and the degree of automation is high.

Description

technical field [0001] The invention relates to a technology in the field of sludge and wet garbage treatment and resource utilization, in particular to a crawler-type multi-layer continuous aerobic fermentation tank equipment and process. Background technique [0002] Existing sludge treatment and disposal are generally processed through processes such as concentration, digestion, dehydration, and drying, and then agricultural, landfill, and incineration methods or a combination of several methods are used for treatment. With the prohibition of ocean dumping, the proportion of sludge disposal is gradually decreasing. At the same time, landfills are also subject to stricter restrictions. Recycling of resources after sludge reduction, stabilization, and harmless treatment is becoming increasingly popular. It is important to note that municipal sludge is suitable for use as a substrate for soil improvers or other high-quality slow-release compound fertilizers, but untreated sl...

Problems solved by technology

With the prohibition of ocean dumping, the proportion of sludge disposal is gradually decreasing. At the same time, landfills are also subject to stricter restrictions. Recycling of resources after sludge reduction, stabilization, and harmless treatment is becoming increasingly popular. It is important to note that municipal sludge is suitable for use as a substrate for soil improvers or other high-quality slow-release compound fertilizers, but untreated sludge has a high moisture content, high viscosity, and contains a large number of harmful substances such as pathogenic bacteria, so it cannot be directly applied to the soil. Bio-fermentation technology is generally used to produce fertilizers

[0003] The existing stack-type aerobic fermentation technology occupies a large area and has a long maturity cycle, requiring a large amount of turning machines and manpower. It is greatly affected by the weather and is prone to odor and pathogenic bacteria; the forced-air static stacking system is also vulnerable to climate conditions. and the fermentation process is difficult to adjust according to the condition of the stack, and the degree of automation is low; the friction of the side of the moving floor type and similar continuous fermentation bins is large, the material push resistance is large, and it is easy to block, which seriously affects the operation of the system
