Abstract

The invention discloses a fuel reactor device for chemical-looping combustion. The device consists of a mixing and reaction chamber, an overflow groove, a transition section, a riser and a carbon dioxide separator, wherein the riser is connected with the mixing and reaction chamber through the transition section; the lower end of the riser is provided with a feed port, and the upper end of the riser is connected with the upper end of the carbon dioxide separator; the lower end of the carbon dioxide separator is connected with the mixing and reaction chamber through the overflow groove; the lower end of the mixing and reaction chamber is provided with a grid plate; the lower end of the mixing and reaction chamber is provided with a solid fuel inlet; a discharge port is formed on the outer side of the mixing and reaction chamber; and a loose air port is formed at the lower end of the overflow groove. Due to the large change of cross sections of the riser and the mixing and reaction chamber change, and the selection of the position of the feed port, the device has the advantages of improving the oxygen carrying capacity of oxygen carrier and guarantees discharge of clean carbon dioxide in chemical-looping combustion, and solving the problem that clean carbon dioxide cannot be obtained during hydrogenation in chemical-looping hydrogenation.

Description

technical field

[0001] The invention relates to a chemical loop combustion fuel reactor device. In particular, it relates to chemical looping combustion fuel reactor devices capable of separating carbon dioxide. Background technique

[0002] The problem of global warming caused by greenhouse gas emissions is attracting people's attention. CO 2 As the most important greenhouse gas, the study of CO 2 Emission reduction technologies are imminent. CO in flue gas 2 Often diluted with large amounts of nitrogen, CO 2 The cost of separation and recovery is very high. High concentrations of CO are produced during combustion 2 or facilitate CO 2 It is an effective way to separate the gas phase mixture while eliminating the generation and emission of other pollutants. Chemical loop combustion is a new type of combustion with the above characteristics. The basic principle is to decompose the traditional fuel-air direct contact reaction combustion into two gas-solid reactions wi...
