ABSTRACT:
A compact but highly integrated pollution control system for use with a coal or lignite burning electrical power generating plant utilizes a stabilized continuously monitored and controlled bath through which is passed gaseous effluent containing particulate matter. In one form this may comprise a chimney of partial stainless steel construction for carrying smoke from the furnace of the plant into a body of water contained within an enclosed concrete tank where the water chemically interacts with and precipitates solids from the smoke. Within the tank a dynamic system is established which is held stable both mechanically and chemically during continuous operation. A stainless steel grill mounted just below the surface of the water breaks up air bubbles to entrap solid particles and enhance formation of a sediment. Fumes and vapors formed above the surface of the water are drawn into and scrubbed by at least one fume scrubber mounted at the top of the enclosed tank, with any resulting water being returned to the body of water at the bottom of the tank. Acid formed in the water by the gaseous emissions is neutralized by a system which adds alkaline solution to the water as necessary to maintain the pH at a nominal value. Water containing the formed sediment at the bottom of the enclosed tank is pumped to one or more clarifiers where a sludge is formed and the remaining water is either disposed of or recycled to the enclosed tank for further use. The sludge formed by the clarifiers is pumped to a compactor which converts the sludge into a non-pourable waste product which is more easily handled and disposed of.
