Apparatus and method for continuous removal, and apparatus and method for recovering and reusing absorbent liquid, and apparatus and method for recovering absorbent liquid from discharged clean gas and returning to storage tank.

In order to effectively absorb the polluting gas by using the droplets, the scrubber has been researched into various methods of forming and cleaning liquid droplets, liquid films, and the like, and various ones are commercially available.

The scrubber apparatus currently used generally includes a spray tower, a packed scrubber, a centrifugal force scrubber, a venturi type, a swirl flow type, and all the apparatuses are designed to maximize the contact between the absorbing liquid and the pollutant gas.

The conventional scrubber device is typically utilized a technology in which the contaminated gas is purified in the absorption tower by introducing the contaminated gas from the lower side opposite to the absorbing liquid injected from the upper through the nozzle. This technique has a very short residence time because the injected absorbent liquid moves to the lower part rapidly. As the droplets and droplets collide with each other, they become large droplets. As a result, the absorption efficiency is not only low. The disadvantage is that it does not contribute significantly to absorption. In addition, when particles or salts are contained in the absorbent liquid sprayed through the nozzle, the nozzle may be clogged very much.

In addition, the prior art is disclosed in the Republic of Korea Patent (Registration No. 1002804200000 No. 5, 2003) is a double-plate plate-attached porous plate scrubber method, but similar to the distillation column due to the pressure drop and the presence of salt or particles The problem is that clogging occurs easily.
