ABSTRACT:
A self-contained wet type pumpless gas pollution control and sludge-handling system, applicable for dusts, vapors, aerosols, mists and fumes, comprises the open-to-the-atmosphere liquid pollutant extractor (17) hydraulically interconnected with the gas pollutant extractor (28). The system makes use of the aerodynamic force of the exhaust fan to circulate a waterfall contaminant capture system and accumulate floats in the extractor (17) available for removal at any time. The unique concept of the open and easily accessible liquid pollutant extractor provides various types of the hydraulically automated floats removal at any time, avoiding a drainage of the system, i.e. preventing a water pollution. The diffusion control feature originates an operating liquid level, prevents and supresses fire, and provides a static pressure feedback control to stabilize a desired amount of the gas flow in spite of unexpected fluctuations of the flow resistance in the exhaust system. The original feature of the invention assists to cool exhaust gases and enables a heat recovery from the working liquid. The invention can be used for a dual purpose as an air pollution control and as an element of a technological process, where pollutant soluble in a liquid creates a new product.
