An industrial tail gas energy conversion system

Abstract

The invention discloses an industrial tail gas recycling system. In the industrial tail gas recycling system, a microalgae oil production device is organically coupled with a synthesis gas fermentation strain growth tank and a synthesis gas fermentation strain fermentation tank. By the industrial tail gas recycling system, CO2 and CO in the tail gas can be recycled effectively, so that two types of clean energy, namely ethanol and diesel, and a few of acetic acid by-products can be obtained. Thus, components of the industrial tail gas can be treated fully through a biologic mode, energy is recycled; therefore, pollution of industrial tail gas emission to the environment can be relieved; and the industrial tail gas energy recycling system has significant use value.

Description

Technical field: [0001] The invention belongs to the field of waste gas treatment and clean energy development, and mainly relates to a system for energy utilization of industrial tail gas. Background technique: [0002] Industrial factories emit a large amount of carbon oxides into the atmosphere every year, which not only wastes energy but also brings huge pressure to the environment. Among them, the problem of carbon dioxide emissions from energy-intensive industries such as synthetic ammonia industry, petroleum refining industry, steel mills, and wood pulp and paper industry is particularly prominent. Carbon oxides emitted by these industries place a heavy burden on the environment. [0003] Microalgae are a group of rapid utilization of CO 2 , and at the same time produce oily organisms, it is widely used in the production of biodiesel. In addition to the lipid components of microalgae itself, it also has abundant sugars available, so microalgae is an extremely suita...
