摘要：NOVELTY - Industrial coke oven gas ammonia recovery method involves introducing industrial coke oven gas into oil removal tank for oil removal and oil mist removal, and then introducing the gas into a single-stage/multi-stage rotational flow injection adsorber, while suction ammonia industrial water is entered into single-stage, tangentially feeding industrial coke oven gas from inlet of top of single-stage or multi-stage rotational flow injection adsorber, spraying ammonias absorption industrial water from side wall small hole of single-stage or multi-stage rotational flow injection adsorber. USE - Industrial coke oven gas ammonia gas recovery method (claimed). DETAILED DESCRIPTION - Industrial coke oven gas ammonia recovery method involves introducing industrial coke oven gas into an oil removal tank for oil removal and oil mist removal, and then introducing the gas into a single-stage or multi-stage rotational flow injection adsorber, while suction ammonia industrial water is entered through a pump into a single level, tangentially feeding industrial coke oven gas from inlet of top of single-stage or multi-stage rotational flow injection adsorber, spraying ammonias absorption industrial water from a side wall small hole of single-stage or multi-stage rotational flow injection adsorber, cutting streamline absorbent sprayed in radial direction into industrial coke oven gas which rotates at high speed, and forming several adsorption liquid droplets, flowing out absorption liquid rich in ammonia gas after absorption from bottom of single-stage or multi-stage rotational flow injection adsorber, then heat exchanging through a heat exchanger, and introducing liquid into a liquid storage tank to be recycled and stored, flowing out the purified industrial coke oven gas from top of single-stage or multi-stage rotational flow injection adsorber, and then through a dryer dehydrating through a subsequent device. An INDEPENDENT CLAIM is included for an industrial coke oven gas ammonia recovery apparatus, which comprises an oil tank for removing oil mist from industrial coke oven gas, a single stage or multi-stage rotational flow injection adsorber for adsorption of ammonia in industrial coke oven gas, a heat exchanger that is connected to a single stage or multi-stage rotational flow injection adsorber for cooling liquid, and a dryer that is connected to the single stage or multi-stage rotational flow injection adsorber for removing liquid phase in the purified coke oven gas, and a liquid storage tank which is connected to the heat exchanger for recovering the stored aqueous ammonia.
