Problems solved by technology

However, since the chemical absorption method utilizes the chemically reversible reaction of the absorbent, the regeneration of the absorbent not only needs to provide the reaction heat of the reverse reaction, but also needs to provide high sensible heat of solution and latent heat of steam vaporization, thus consuming a large amount of steam and increasing CO 2 capture cost

Abstract

The invention provides a solar heating system, and the solar heating system is communicated with a regeneration tower of a gas chemical absorption regeneration system and is used to heat a rich solution of an absorbed gas of the regeneration tower. The solar heating system comprises a solar heat collector, a high-temperature heat-conduction fluid storage tank, a low-temperature heat-conduction fluid storage tank, a high-temperature heat-conduction fluid pump, a low-temperature heat-conduction fluid pump, a heat-conduction fluid circulation pump and a multistage boiler. The multistage boiler is in parallel connection with the regeneration tower. According to the solar heating system, the solar heat collector acquires solar energy and fully utilizes solar energy to replace steam heating, and thus energy consumption is reduced. Also, the multistage boiler is in parallel connection with the regeneration tower of the gas chemical absorption regeneration system, so that the efficient heat collection ability of solar energy is utilized for fully satisfying the desorption temperature requirement of the rich solution.

Description

technical field [0001] The invention relates to the field of renewable energy utilization, in particular to a solar heating system. Background technique [0002] At present, CO commonly used in the world 2 Separation methods include absorption method, adsorption method and membrane separation method. Absorption method is the earliest researched, most widely used and mature CO2 separation method. 2 capture method. The absorption method is to use absorbent and CO 2 CO enrichment by physical or chemical process in absorber 2 , and then desorb the absorbent in the regeneration tower to obtain high-purity CO 2 , while the absorbent is reduced. [0003] The organic amine absorption method is the most widely used chemical absorption method, and its CO 2 The separation efficiency can reach about 98%. However, since the chemical absorption method utilizes the chemically reversible reaction of the absorbent, the regeneration of the absorbent not only needs to provide the reacti...
