Integrated equipment and method for high-temperature aerobic fermentation of low-water-content sludge

Abstract

The invention relates to integrated equipment and a method for high-temperature aerobic fermentation of low-water-content sludge. The integrated equipment comprises a supporting frame and a plurality of supporting legs mounted on the supporting frame, the device further comprises a fermentation cylinder, a first side plate and a second side plate are rotationally installed at the two ends of the fermentation cylinder respectively, the first side plate is hinged to the supporting frame, and the second side plate abuts against the supporting frame and is fixed through a locking piece when the fermentation cylinder is in a horizontal placement state. The fermentation cylinder is driven to rotate by a driving piece mounted on the support frame; a rotation driving mechanism is mounted on the supporting legs, is connected with a bearing ring which is rotatably mounted on the outer side of the fermentation cylinder, and is used for driving the fermentation cylinder to rotate; a plurality of groups of shoveling plates are mounted on the inner side of the fermentation cylinder, the heights of every two adjacent groups of shoveling plates are different, spiral battens are respectively arranged at the two ends of the inner side of the fermentation cylinder, and the spiral directions of the two spiral battens are opposite.

Description

technical field [0001] The invention relates to the technical field related to fermentation, in particular to an integrated equipment and method for high-temperature aerobic fermentation of sludge with low water content. Background technique [0002] Aerobic fermentation can be divided into two stages: rapid composting and maturation, in which in-silo composting and strip composting are the rapid composting stages. The stacked equipment is simple, but the stacking height is low and the floor space is large. Due to the limited oxygen supply, long fermentation period and low surface temperature of the heap, it is not suitable to meet the requirements of harmlessness, and the sanitary conditions are poor. [0003] The composting in the warehouse can be in the form of rectangular troughs with mechanical horizontal stacking, circular troughs with mechanical circular stacking, and "Dano" drums. The disadvantages of the existing technology are as follows: [0004] 1. Aerobic ferm...

AI Technical Summary

Problems solved by technology

[0005] 2. The material needs to stay in the device for a long time (generally 8-15 days) to fully aerobic fermentation, which affects the processing capacity and output of the device

The monitoring system is not perfect during the aerobic fermentation process, resulting in a lag in the quality control process;

[0006] 3. The microbial agent added in the aerobic fermentation process greatly increases the operating cost
