Abstract
The invention provides a waste gas purification apparatus and residual heat utilization and control device for intelligent printing and dyeing waste gas. The apparatus includes: a circulating water storage tank; a liquid circulation tank; a water filtration system, connected to the storage tank; a bubble generation device, connected to the storage tank; and an organic waste gas removal device. An upper end of the waste gas removal device is connected to the bubble generation device and the liquid circulation tank, and a lower end is connected to the liquid circulation tank. The utilization and control device includes a residual heat cascade utilization unit, a spraying unit, a composite pulse static absorption column unit, a twin-stage high-temperature water white smoke elimination unit, and an air discharge unit sequentially disposed in a waste gas flow direction, and includes an oil-water separation box, a sodium chloride electrolysis device, and the purification apparatus.
