Abstract:
1. A reaction furnace utilizing high-temp steam and recirculated heat source to separate mercury and crack dioxin and organic substances contained in waste, comprising: a first combustion chamber being provided with a burner to produce high-temp hot gas; and a second combustion chamber being provided with a gas inlet, a gas outlet, a reaction chamber, and a high-temperature steam generator; and the reaction chamber being provided with a feed inlet, a gas mixture outlet, and a discharge outlet; and waste to be treated being introduced into the reaction chamber via the feed inlet; the high-temp hot gas produced in the first combustion chamber being introduced into the second combustion chamber via the gas inlet to heat the reaction chamber and the high-temp steam generator of the second combustion chamber, and becoming cooled down before being discharged via the gas outlet; high-temp steam produced by the high-temp steam generator being introduced into the reaction chamber, so that mercury, organic substances, and dioxin in the waste are distilled and carried away by the steam; gas mixture produced during the reaction process being discharged via a gas mixture outlet to a gas mixture treatment system for separation; fuel gas and fuel oil separated from the gas mixture by the gas mixture treatment system being introduced into the burner of the first combustion chamber for producing the high-temp hot gas, and waste water separated from the gas mixture by the gas mixture treatment system being led to the high-temp steam generator for producing the high-temp steam; and soil contained in the waste having been treated in the reaction chamber being discharged via the discharge outlet.
