Abstract
A contact reaction tower, including: a central cylinder; and an outer cylinder. Lift pipes and a water inlet pipe(s) are installed in the central cylinder, reflux windows are formed on the wall of the central cylinder, and the water flow circulation between the central cylinder and the outer cylinder is realized through the lift pipes, the water inlet pipe(s), and the reflux windows, such that the water flow internal circulation of the whole contact reaction tower is realized. The contact reaction tower is sealed in its entirety from the outside environment, and a gas guide pipe is installed at the top of the contact reaction tower.
