Ecological cyclic utilization system for organic waste

Abstract

The invention discloses an ecological cyclic utilization system for organic waste. The ecological cyclic utilization system comprises: a collection system; a reaction system, which is composed of an anaerobic fermentation device and a conditioning, turning and throwing unit, wherein the collection system is connected with the anaerobic fermentation device, and the anaerobic fermentation device is connected with the conditioning, turning and throwing unit; and a low temperature drying device, which is composed of a shell, a heating pipe and a first vacuum pump, wherein the heating pipe is arranged at the bottom in the shell in a coiled way and forms an annular shape or rectangular-ambulatory-plane shape, the upper part of the heating pipe is provided with a screen which has thermal conductivity and is used for feeding a material, the screen is arranged to be in a waveform, abuts against the heating pipe and is heated by the heating pipe, the first vacuum pump is communicated with gas in the shell, and the the conditioning, turning and throwing unit is connected with the low temperature drying device.

Description

technical field [0001] The invention relates to the field of organic waste recycling, in particular to an organic waste ecological recycling system. Background technique [0002] In recent years, with the development of the livestock and poultry industry towards specialization, scale, and intensification, the discharge of organic pollutants from livestock and poultry has increased and concentrated, and the concentrated production of livestock and poultry manure has continued to increase, causing serious harm to the environment. [0003] (1) Emissions of harmful gases and greenhouse gases. There are nearly 200 kinds of harmful gases, which affect the quality of life of surrounding residents (the smell is unbearable); the annual greenhouse gas emissions of large-scale farms are more than tens of thousands of tons of CO2 equivalent. Some harmful substances in solid organic waste, such as protein and fatty acid corruption products (also the constituent substances of solid organ...

Problems solved by technology

[0004] (2) Pollution of water bodies

[0005] (3) Contaminated soil

[0011] (1) In terms of technology, the biogas residue, biogas slurry, and wastewater produced after anaerobic fermentation are not fully utilized, and even cause secondary pollution;

[0012] (2) Traditional organic waste treatment is usually aimed at the removal of pollutants, which consumes a lot of energy and wastes a lot of resources. Even if resource recovery is adopted, it does not proceed from the overall system point of view. The method of simply recycling waste and garbage resources combined with wastewater treatment cannot Taking into account both environmental protection and economic value;

[0013] (3) The equipment and process are not matched, the lack of systematic complete equipment and standardized manufacturing quality is poor, the failure rate is high, and the long-term stable and reliable operation cannot be performed;

[0014] (4) The project construction unit only takes project construction as its profit goal, does not guarantee daily operation and management, cannot produce economic benefits, the profitability of the project is not obvious, and the owner's enthusiasm for operation is not high

[0015] Especially in the process of using biogas residues to prepare organic bio-fertilizers, it generally takes a long time to dry biogas residues, and the drying efficiency is low, which fundamentally reduces the production efficiency of organic fertilizers.

In addition, because the general drying device adopts high-temperature drying technology, most of the beneficial microorganisms in the biogas residue will be killed, thereby reducing the use effect of organic fertilizers
