A rail car type anaerobic-aerobic combined fermentation composting device

Abstract

The invention relates to a rail car type anaerobic-aerobic combined fermentation and composting device, comprising a liquid storage tank, a sealed box-type casing, and an anaerobic fermentation device and an aerobic fermentation device located in the box-type casing; The box-type housing is provided with a mobile fermentation tank, and the mobile fermentation tank has the first and second working states located in the anaerobic fermentation device and the aerobic fermentation device; the anaerobic fermentation device is sealed, and the bottom is provided with a second A liquid storage tank with a spray head on the inner top; the aerobic fermentation device is provided with an odor outlet pipe and an air intake pipe extending from the outside of the box-type casing to the aerobic fermentation device; the bottom is provided with a second storage tank Liquid tank; the liquid outlets of the first and second liquid storage tanks are connected to the liquid inlet of the liquid storage tank, and the liquid outlet of the liquid storage tank is connected to the spray head. The invention is suitable for high-efficiency clean composting treatment and high-efficiency utilization of all components of multiple wastes, and is especially suitable for comprehensive utilization of multiple wastes mainly in counties or villages.

Description

technical field [0001] The invention relates to a rail car type anaerobic-aerobic combined fermentation composting device, which belongs to the technical field of agricultural machinery. Background technique [0002] Anaerobic fermentation refers to the process in which organic substances (such as human, livestock and poultry manure, straw, weeds, etc.) are catabolized by various microorganisms under certain moisture, temperature and anaerobic conditions, and finally form flammable mixed gases such as methane and carbon dioxide. process. After anaerobic fermentation is completed, a large amount of product biogas slurry and biogas residue need to be properly treated and utilized to prevent environmental pollution and waste of resources. [0003] Composting is a clean and efficient way to treat biogas slurry and biogas residues. It uses microorganisms such as bacteria, actinomycetes, and fungi widely distributed in nature, and under certain artificial conditions, it promotes ...

AI Technical Summary

Problems solved by technology

[0004] At present, multivariate wastes (mainly crop straws, vegetable straws, perishable garbage, livestock and poultry manure, toilet manure, etc., and some organic matter such as mushroom residues and Chinese herbal medicine residues) in villages or counties are complex. , various properties, firstly, the existing anaerobic devices and composting devices usually can only process part of the waste due to the device structure and process requirements; secondly, a single anaerobic fermentation method will produce a large amount of biogas slurry and biogas residue, requiring Secondary treatment, the single aerobic composting method has a long fermentation cycle, poor decomposing degree, and easy to produce leachate to pollute the environment, etc.
