Carbon absorption tower

Abstract

The invention discloses a carbon absorption tower. The key points of the invention are as follows: the tower is sequentially provided with the four parts of, from top to bottom, an ammonia purifying section, a carbon absorbing section, an ammonia absorbing section and a carbon absorbing liquid storage tank; the four parts are separated by three spacing boards; the top of a tower body is provided with a tail gas outlet, and the bottom of the tower body is provided with a carbon absorbing liquid outlet; the tower is a bamboo hat tower, the ammonia purifying section, the carbon absorbing section and the ammonia absorbing section are provided with a plurality of bamboo hats and a plurality of liquid overflow pipes, and the liquid overflow pipes are arranged at two sides of the tower body; each section is provided with a liquid inlet, a liquid outlet, a flue gas inlet pipe and an air inlet cap and an outlet thereof; water retainer rings of the carbon absorbing section and the ammonia absorbing section are arranged below a flue gas outlet; a defogging tray of the ammonia purifying section is arranged below the flue gas tail gas outlet; and a finished product from the ammonia absorbing section enters into the carbon absorbing liquid storage tank. The invention has the following advantages: the tower has integrated functions of dissolving and absorbing CO2 and demisting, which enables the process flow for carbon absorption to be simplified and small equipment investment and convenient operation to be obtained; the tower is capable of continuous operation, is stable and reliable and is a high efficiency carbon recovery apparatus, with the absorption rate of CO2 being more than 85%.

Description

Technical field [0001] The invention relates to a carbon absorption tower, in particular to a carbon absorption tower that uses secondary brine and ammonia brine of an ammonia-soda enterprise to absorb carbon dioxide in boiler flue gas. Background technique [0002] With the rapid economic development, environmental protection issues have become increasingly prominent. Among them, carbon dioxide is an important part. The "greenhouse effect" caused by its excessive emissions has attracted widespread attention in today's society. How to reasonably use carbon dioxide and reduce the environmental problems caused by this has become a common research topic for all mankind. To develop a low-carbon economy, one is to start with the adjustment of the industrial structure and energy structure; the other is to seek energy-saving ways and promote energy-saving technologies in the entire process of design, production, and consumption from all aspects of the industry. [0003] As an important ...
