Abstract

The invention provides a regeneration method of organic adsorbed saturated active carbon. The adsorbed saturated active carbon flows in a gasification cracking furnace to be regenerated; the process is divided into three phases when the adsorbed saturated active carbon flows to a furnace tail from a furnace head of the gasification cracking furnace: a drying phase: the drying temperature is 80-150 DEG C and the drying time is 3-20 minutes; a desorption phase: the desorption temperature is 350-700 DEG C and the desorption time is 20-150 minutes; an activation phase: the activation temperature is 750-1200 DEG C and the activation time is 5-150 minutes, water steam is introduced at the activation phase, and the ratio of the introduction amount of the water steam to the weight of the active carbon is 100-500ml / min to 1kg. The regeneration method has the advantages of capability of realizing continuous production, high heat source utilization rate, stable regeneration performance of the active carbon, high yield, no pollution, small labor intensity and the like.

Description

technical field [0001] The invention relates to the technical fields of energy saving, environmental protection and resource regeneration, in particular to a regeneration technology for producing saturated activated carbon by utilizing waste heat of fuel oil combustion. Background technique [0002] Activated carbon has a highly developed pore structure and a large specific surface area, and is widely used in various industries. It can effectively adsorb harmful substances in water, such as organic matter and heavy metal ions, to purify wastewater. However, the high price of activated carbon makes it difficult to put activated carbon into practical application. In addition, activated carbon is also a product that consumes a lot of resources and energy. If the saturated activated carbon is not recycled, it will be a great waste of resources and will cause secondary pollution. [0003] At present, the technologies for regeneration of saturated activated carbon mainly include...
