Static aerobic fermentation drying tower and application

Abstract

The invention relates to a static aerobic fermentation drying tower and an application and belongs to the technical fields of agricultural organic waste resource utilization and environmental protection. The invention solves the problems of exposed production, easily caused secondary pollution, low resource utilization, large volume of organic raw materials and inconvenient carrying and the like of the existing composting technology. The invention comprises a fermentation drying tower which is built at a required minimum driving height of a forklift and a tower-type sealing fermentation and internal ventilation structure, and by utilizing accumulated temperature effect generated by whole fermentation and backflow circulation of high-temperature and high-moisture fermentation heat, static fermentation, drying and microorganism multiplication culture are finished once. By utilizing the fermentation heat, the moisture content of dry materials can reach below 25 percent, and simultaneously, the medium-temperature fermentation time is prolonged, the fermentation cycle is shortened, and active substances are kept to the greatest extent. The fermentation drying tower and the civil work of a tower body are integrated, thus saving the investment and being durable, and the application of a normal loading machine has high efficiency and low production cost. The product is high-quality organic fertilizer or bio-organic fertilizer if microorganisms with specific functions are added.

Description

technical field [0001] The invention relates to a static aerobic fermentation drying tower for industrialized production of organic fertilizer and bio-organic fertilizer by utilizing livestock and poultry manure in breeding industry, organic waste in agriculture or food industry and its application. It belongs to the recycling technology of agricultural organic waste resources and environmental protection technology. [0002] Organic fertilizer fermentation technology, that is, composting technology, is a process that uses the action of microorganisms to accelerate the biodegradation and transformation of organic matter under controllable conditions, and finally makes the organic matter decompose and stabilize. Fermentation products, i.e. organic fertilizers or bio-organic fertilizers. [0003] According to the definition of terms in the NY525-2002 industry standard of the Ministry of Agriculture, organic fertilizers are mainly carbon-containing materials that are mainly deri...

AI Technical Summary

Problems solved by technology

Due to the vertical structure, the material layer is thin, which can ensure 24-hour aerobic fermentation of compost materials, but the output is low and the equipment is easy to corrode. The anti-corrosion biological fermentation drying tower disclosed by the inventor in ZL03235516.5 better solves the problem of equipment corrosion. However, there are still problems such as large investment, short fermentation cycle, high product moisture, fire drying, high post-processing cost, pollution, and heating to maintain the minimum fermentation temperature in northern regions and winter.
