Description

TECHNICAL FIELD

[0001] The utility model relates to carbon dioxide emission reduction technical field, in particular to a kind of high-efficiency energy-saving carbon dioxide emission reduction device. BACKGROUND

[0002] The emission of carbon dioxide is harmful to the atmospheric environment, causing the greenhouse effect. To protect the atmospheric environment, carbon dioxide emission reduction devices are used to reduce emissions when waste gas is discharged. One of the existing treatment methods is chemical adsorption, which uses carbon dioxide treatment reagent (such as potassium carbonate plus activator) to absorb carbon dioxide gas for later use.

[0003] Chinese patent CN218188895U discloses a device for reducing carbon dioxide emissions in coal chemical industry. By setting up an air inlet pipe, a first partition, a spray plate, a second partition, and a circulating spray assembly, the spray plate cooperates with the circulating spray assembly to facilitate the circulation of carbon dioxide treatment reagent. The first partition cooperates with the second partition to effectively extend the path of the gas through the spray chamber, allowing the gas to fully contact the carbon dioxide treatment reagent, which helps to improve the treatment effect of carbon dioxide. By setting up a spray chamber, a liquid storage chamber, and an aeration assembly, the aeration assembly facilitates the introduction of treated gas from the spray chamber into the liquid storage chamber, which not only helps to improve the treatment effect of carbon dioxide but also facilitates the use of gas to stir the carbon dioxide treatment reagent in the spray chamber, thereby eliminating the need for additional driving equipment for stirring, which helps to reduce energy consumption.

[0004] The device can mix carbon dioxide and adsorption liquid through spraying and solve the stirring problem and improve the adsorption effect of carbon dioxide through aeration. However, in actual use, the aeration and circulating water pool are integrated, making it easy for the circulating pump to mix air when extracting adsorption liquid. The internal extraction of air by the circulating water pump is prone to wear and tear, affecting the service life. Therefore, a high-efficiency energy-saving carbon dioxide emission reduction device is proposed. UTILITY MODEL CONTENTS
