Industrial tail gas recycling 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 plants emit large amounts of carbon and oxygen compounds into the atmosphere each year, which not only wastes energy but also puts huge pressure on the environment. Among them, the problem of carbon and oxygen emissions from energy-intensive industries such as the synthetic ammonia industry, petroleum refining industry, steel mills, and wood pulp and paper industry is particularly prominent. The carbon and oxygen compounds emitted by these industries place a heavy burden on the environment. [0003] Microalgae is a kind of rapid utilization of CO 2 , And at the same time produce oils and fats, it is widely used to produce biodiesel. In addition to the lipid content of microalgae itself, it also has rich sugars available for use, so microalgae is an ext...

Problems solved by technology

[0010] It can be seen from the above that although the synthesis gas fermentation strain has the unique ability to utilize CO in the tail gas, its efficiency is low, and under the condition of lack of reducing power, some CO 2 produce
