Abstract

The application relates to the field of alcohol extraction devices, in particular to a device and method for preparing alcohol through continuous gas fermentation. The device comprises a fermentation vessel; a gas intake pipeline; a liquid inlet pipeline; an exhaust pipeline; a discharge pipeline; a circulating pipeline, wherein the circulating pipeline communicates with the fermentation vessel and is used for circularly using feed liquid in the fermentation vessel, the circulating pipeline is provided with a heat exchange element and a power element, the heat exchange element is used for maintaining a fermentation temperature, and the power element is used for providing power for circulating the feed liquid; and a permeable membrane kit, wherein the two ends of the permeable membrane kit communicate with the heat exchange element and the fermentation vessel separately, the permeable membrane kit comprises a membrane assembly, a first outlet end of the membrane assembly communicates with a self-circulation pipeline of the membrane assembly, and the membrane assembly is used for separating the alcohol from fermentation liquor. Continuous ventilation can be carried out, and alcohol substances are continuously extracted by utilizing the permeable membrane assembly, so that the purpose of preparing the alcohol by using a large amount of industrial gas containing low-concentration carbon monoxide is achieved.

Description

technical field [0001] The present application relates to the field of alcohol extraction devices, in particular to a device and method for continuous gas fermentation to produce alcohol. Background technique [0002] With the increasing tension of global fossil fuels and increasingly serious environmental pollution, the energy and environmental crisis has become a major obstacle to the sustainable development of human society in the 21st century. [0003] Ethanol is a good solvent and can also be used as a raw material for the preparation of various chemical products. Grain ethanol is heavily dependent on agricultural grain crops, and the development of the policy of "not competing with the people for food and land" is the direction of the development of fuel ethanol in my country and the world; the production cost of non-grain ethanol and biomass ethanol has been high, mainly The cost lies in the raw materials and production equipment. Industrial tail gas has a wide range ...
