Embodiment Construction

[0013] The integrated fixed bed chemical looping combustion device works as follows:

[0014] The present invention has designed a set of integrated chemical looping combustion device, and its specific structure is as follows figure 1 As shown, its structure will be described in detail below.

[0015] The device is composed of three parts, namely tank part, pipeline part, solenoid valve part controlled by PLC, combustion product and waste gas collection part. The tank part is a sleeve structure, consisting of two cylinders, the inner cylinder can be used as an air reactor (fuel reactor), and the space between the outer cylinder and the inner cylinder wall can be used as a fuel reactor (air reactor) ), the wall of the inner cylinder is perforated, and the perforated part is provided with a solenoid valve switch.

[0016] The pipeline part is composed of a pipeline and a solenoid valve. One side of the pipeline is connected to the tank body, and the other side of the pipeline ...

Abstract

The invention relates to the technical field of high efficient combustion and clean energy sources and discloses a novel integrated fixed bed chemical looping combustion device. The device aims to solve the problems of a conventional chemical looping combustion device, and the conventional equipment is improved integrally, so that the reaction rate and the combustion efficiency are improved to themaximum extent. By integrating the conventional chemical looping combustion device, the conventional chemical looping combustion device is integrated to convert action of an air reaction chamber anda fuel reaction chamber alternately to achieve alternate oxidizing reactions and reduction reactions in the combustion process, so that continuous reactions of the chemical looping combustion system are guaranteed and therefore, the reaction rate of combustion is improved, the heat loss in the reaction process is also reduced, and the energy source is utilized to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of high-efficiency combustion and clean energy, in particular to a novel integrated fixed-bed chemical looping combustion device. Background technique [0002] Chemical looping combustion is a promising combustion method. The chemical looping combustion system has high efficiency and zero energy dispersion to separate CO 2 The chemical chain technology is a new type of chemical conversion and energy can be used rationally. This technology decouples the chemical conversion process of traditional combustion into two or more reaction processes to achieve efficient use of energy and low-energy separation of substances. From the perspective of chemical reaction, a chemical chain decouples a specific chemical reaction into a multi-step chemical reaction in multiple reactors, realizing the indirect contact of multiple reactants; from the perspective of energy utilization, a chemical chain can The realization of ...
