Abstract

The invention relates to the technical field of waste heat power generation, in particular to a dry-process CO2 capture low-temperature waste heat power generation system. The system comprises a dry-process CO2 capture system part, a system internal heat energy comprehensive collection part and a heat utilization part. The dry-process CO2 capture system part comprises a second-stage cooler, a first-stage cooler, a CO2 dust remover, a regeneration tower, an absorption tower, a cyclone separator, a bag-type dust remover, a cooler, a discharging chute, and connecting pipelines and valves of the discharging chute. The system overcomes the defects in the prior art, reaction heat in the CO2 capture process and waste heat resources in the CO2 absorbent regeneration process can be systematically utilized in a gradient mode, circulating cooling water originally needing to additionally consume energy is replaced with a circulating hot working medium, the heat energy grade of the hot working medium is improved as much as possible, the obtained heat is used for low-temperature working medium power generation, and the effects of reducing the energy consumption of the original system and generating energy products are achieved.

Description

technical field [0001] The invention relates to the technical field of waste heat power generation, in particular to a low-temperature waste heat power generation system for dry CO2 capture. Background technique [0002] Global climate change caused by greenhouse gas emissions such as carbon dioxide has become one of the biggest challenges facing mankind in this century. CCUS (Carbon Capture, Utilization and Sequestration) refers to carbon capture, utilization and storage, which is to collect carbon dioxide for utilization or storage. As a carbon-negative technology, CCUS is the only hope for the survival of coal, coal chemical, petrochemical and other industries under the goal of carbon neutrality in large-scale and low-cost commercialization, and will release a huge market size. At present, the CO2 capture process and absorbent regeneration process require a large amount of energy, and the high operating cost is the main factor restricting the widespread application of CC...
