High-efficiency ecological recycling system of maize straw and technological process

Abstract

The invention belongs to the technical field for ecological recycling of agricultural and sideline products, and particularly relates to a high-efficiency ecological recycling system of maize straw and the technological process. The maize straw is obtained from maize planting bases, and is crushed by a maize straw processing apparatus, and then is briquetted to prepare solid fuel or to provide to a winery for fermentation by yeast, so as to prepare wine and obtain ethanol fuel, lees and the produced maize, which are provided to a livestock and poultry farm for feeding livestock and poultry, the excrement of livestock and poultry is used in a fish farm and earthworm farm and put into a biogas generator, so as to provide clean gas fuel for the winery and life of people. Meat of livestock and poultry, eggs and fish are the organic foods in life of people, earthworm is used as feed of fish and poultry, the excrement of earthworm is returned to farmland, earthworm can loosen soil so as to improve the fertility of soil and the yield of maize. Thus, a benign ecological recycle system is formed, a circulating economical industrial chain of ecological agriculture is formed, and zero release is realised in the process of treating the maize straw. The invention fundamentally solves the problem of difficult market sale and greatly improves the net incomes of enterprises and farmers.

Description

technical field [0001] The invention belongs to the technical field of ecological recycling of agricultural by-products, and in particular relates to a high-efficiency ecological recycling system and process flow of corn stalks. Background technique [0002] Corn stalks are an important by-product of crops, a production resource for industry and agriculture, and a resource for renewable energy. As a large agricultural country in my country, the total annual output of corn stalks reached 182 million tons (air-dried, water content 15%) in 2006, and it was as high as 120 million tons in Northeast China and North China alone. However, in recent years, the output of corn stalks in my country has increased rapidly with the continuous improvement of the unit output of major grain products, and the traditional straw utilization methods have gradually been weakened and eliminated. Some farmers have adopted the simplest way to deal with the prominent problems in production - burning o...

Problems solved by technology

However, in recent years, the output of corn stalks in my country has increased rapidly with the continuous improvement of the unit output of major grain products, and the traditional straw utilization methods have gradually been weakened and eliminated. Some farmers have adopted the simplest way to deal with the prominent problems in production - burning or dumping randomly, which not only wastes precious resources, but also causes a lot of social, economic and social damage such as air pollution, soil mineralization, fires and traffic accidents. Ecological issues have become hot and difficult points of government concern, social concern, and public opinion concern

[0003] However, the transformation speed of agricultural scientific and technological achievements in my country is slow and the conversion rate is low. One very important reason is that although a large number of scientific and technological achievements have advantages such as advanced technology or mature and reliable technology, they are promoted as a single technology, either because of narrow market demand or because of Due to high promotion costs or low economic benefits, it is difficult to transform into productivity; especially in the fields of ecological agriculture and circular economy, the transformation as a single technology is slower
