Embodiment Construction

[0020] as attached figure 1 As shown, choose an appropriate location near the fish pond to build a large-scale breeding base, and build several biogas digesters (or a large biogas digester) and a small distillation processing plant nearby. Firstly, the order is used to encourage nearby farmers to plant a large number of sweet potatoes, and then the mature sweet potatoes are purchased, and the sweet potatoes are crushed and filtered by the crushing equipment of the processing plant to obtain starch and potato residue. Starch can be made into various green foods (such as vermicelli, etc.) or sold as industrial raw materials. Sweet potato residue is fermented and distilled to produce fuel ethanol. The equipment for producing fuel ethanol includes a heating distillation system and a dry storage room. The heating distillation system is composed of a gas fuel stove 1, a gas fuel heating chamber 3, a fixed fuel stove 4 and a solid fuel heating chamber 8, a dual heat source device, a ...

Abstract

The invention relates to a heat energy self-supporting ecological circulation technology for preparing fuel ethanol with sweet potato residue raw material which depends on the feeding industry, uses animal excrement to prepare biogas, and then uses biogas as heat energy to perform the fermentation of sweet potato residue raw material and prepare fuel ethanol. The invention also relates to process flows of the heat energy self-supporting ecological circulation technology for preparing fuel ethanol with sweet potato residue raw material and devices thereof. The invention also relates to an organization and management mode of the heat energy self-supporting ecological circulation system for preparing fuel ethanol with sweet potato residue raw material. Compared with the existing technology for preparing fuel ethanol, the technology of the invention does not consume grain, can increase the production of sweet potato so as to promote the production of grain and the development of the pig industry, realize heat energy self-supporting in production and achieve the effect of ecological circulation.

Description

1. Technical field [0001] The invention relates to a process for preparing fuel ethanol from potato residues. In particular, it relates to a self-sufficient heat energy self-sufficient potato dregs raw meal fuel ethanol ecological cycle process. 2. Background technology [0002] In recent years, international oil prices have continued to rise, and countries are competing to develop alternative energy sources (such as: fuel ethanol), which has brought about a series of price increases for food, feed, pork, etc. Recently, world food prices have risen (70% for rice and 120% for wheat). The development of non-food and agricultural alternative energy is a major scientific research topic facing the world. Making wine from potato dregs is a traditional folk craft that has existed since ancient times. However, the taste of the wine is poor, and it is rarely used to make wine. The production of ethanol from potato dregs consumes a lot of energy (the cost of energy consumption acc...
