Abstract An apparatus for decomposing injurious substances to form non-injurious substances comprising a first reaction vessel, an injurious substance inlet connected to the first reaction vessel for supplying an injurious substance containing only one of an oxygen or hydrogen donor substance, and at least one further reaction vessel connected to the first reaction vessel. A mixing vessel connected to the at least one further reaction vessel is provided with the first reaction vessel, the further reaction vessel and the mixing vessel containing an aqueous solution of sodium carbonate. Conduits may be provided between the first reaction vessel, further reaction vessel and mixing vessel, permitting circulation of the aqueous sodium carbonate solution. A feeding device is connected between the mixing vessel and the first reaction vessel for feeding the aqueous sodium carbonate solution therebetween and into association with the injurious substances supplied to the first reaction vessel. Injurious substances are fed by other feeding devices to the mixing vessel for supplying only one of the hydrogen donor or oxygen donor substances. The other of the hydrogen donor and oxygen donor substances are supplied to the injurious substance inlet of the first reaction vessel and water purification devices are connected to the mixing vessel for purifying water coming therefrom.
An apparatus for decomposing injurious gaseous substances to form a non-injurious substance comprising means defining a reaction gas liquid contact tower having a lower portion for holding a reservoir including an aqueous solution of sodium carbonate and an upper portion disposed above said reservoir, inlet means for passing the injurious gaseous substances to be treated into said upper portion, a plurality of spray nozzles for spraying said aqueous solution into said upper portion above said inlet means to contact the gaseous substances, a plurality of serially interconnected reaction vessels, each of said vessels having means for maintaining and holding a reservoir of said aqueous solution at a predetermined level, conduit means for maintaining a predetermined level of said aqueous solution in said tower and for passing said aqueous solution from said tower connecting said lower portion of said tower and one of said interconnected reaction vessels to establish fluid communication between the respective reservoirs thereof, gas discharge means connected to said upper portion of said tower and one of said reaction vessels for supplying at least part of said gaseous substances into the reservoir of said reaction vessel, said gas discharge means having a discharge output without said reservoir of said reaction vessel, pump means for passing gaseous substances from above the level of said reservoir of one of said reaction vessels to below the level of the reservoir of another of said reaction vessels, a mixing vessel connected to at least one of said reaction vessels for receiving said solution therefrom, means for supplying only one of a hydrogen donor or oxygen donor substance to said mixing vessel, mixer means in said mixing vessel for mixing said donor substance and said solution to form a mixture, mixture pump means for passing said mixture to said plurality of spray nozzles, means for separating water from said mixing vessel, and a water purifier means connected to said mixing vessel for purifying water.
