Embodiment Construction

[0023] The following reference figure 1 To explain in detail the CO2 separation of coal and combustible solid waste in a circulating fluidized bed chemical chain combustion of the present invention 2 Method, the oxygen carrier is iron ore (the main component is Fe 2 O 3 ) As an example.

[0024] 1) Circulating fluidized bed solid waste reactor (hereinafter referred to as fuel reactor) 1 The air distribution plate at the bottom is the gasification agent inlet, and there are two inlets on the lower left side. The upper part is the combustible solid waste inlet A and the lower part is coal Particle entrance B. On the right is the first-level return material inlet. Water vapor and CO 2 The mixture is used as the gasification agent and fluidization medium, respectively, from the reactor gasification agent (steam) inlet D and the reactor gasification agent (CO) at the bottom of the fuel reactor 1 2 ) Inlet E enters, carrying the combustible solid waste particles from the combustible s...

Abstract

The invention discloses a device and a method for separating CO2 by circulating fluidized bed chemical looping-combustion of coal and combustible solid waste; the device mainly comprises three portions including a burning reaction system, a separation system and an oxygen carrying reaction system, wherein the burning reaction system is a circulating fluidized bed fuel reactor (1); the separation system comprises a one-stage inertial separator (2), a one-stage inertial separator outlet (3), a one-stage dipleg (4), a two-stage cyclone separator (11), a two-stage cyclone separator outlet (10) and a two-stage dipleg (12); the oxygen carrying reaction system comprises a cross-flow moving bed air reactor (6), a fresh oxygen carrier particle feeder (5), a J-shaped material returning valve (8) and an inactive oxygen carrier particle discharger (C); the method can enable the speed of combustion reaction of coal / combustible solid waste and oxygen carrier to be matched with the speed of oxygen carrying reaction of the oxygen carrier so as to achieve the effects that burning efficiency is high, oxygen carrying capability of the oxygen carriers is strong, concentration of separated CO2 is high, and final CO2 capturing rate is high.

Description

technical field [0001] The invention relates to a device and method for circulating fluidized bed chemical chain combustion of coal and solid waste, and belongs to the technical fields of coal combustion, resource utilization of solid waste and fluidized bed combustion. Background technique [0002] my country is currently the world's largest emitter of carbon dioxide. The pressure from environmental protection and international public opinion forces my country to find an efficient and reasonable CO 2 means of emission reduction. At the same time, my country is also the largest waste producing country in the world, and the year-on-year increase in solid waste production has seriously affected my country's environmental protection and ecological balance. more than half. Due to the limitations of technology and conditions at this stage, the comprehensive utilization rate of combustible solid waste in my country is still very low. The use of chemical chain combustion technolo...
