Abstract
The invention relates to a horizontal-stirring waste powdered activated carbon regeneration furnace, and relates to the field of chemical engineering equipment. The furnace is used for waste powdered activated carbon high-temperature water vapour activation regeneration. The furnace is composed of a steel plate furnace housing, stirring blades, a stirring shaft, a waste waste powdered activated carbon inlet, a regenerated waste powdered activated carbon outlet, oxygen-rich gas inlets, water vapour inlets, oxygen-rich gas distribution plates, a high temperature shielding plate, a regeneration tail gas outlet, a driving machine, and the like. The steel plate furnace housing is fixed in a supported manner, and is lined with a fire-resistant thermal insulation layer. According to the invention, enriched oxygen is used as a combustion improver, such that energy consumption can be saved, furnace temperature can be improved, flue gas flow rate can be reduced, and carbon powder raising can be suppressed. The high temperature shielding plate is arranged in the furnace, such that a temperature gradient is formed along an axial direction in the furnace, organic matter ordered dry distillation is facilitated, the production of organic residual carbon is reduced, and activation regeneration load can be reduced. Under the condition of high temperature, powdered carbon is light and has good fluidity, such that stirrer power is low. The regeneration furnace provided by the invention has the advantages of simple structure and low cost. With the furnace, waste powdered activated carbon regeneration cost can be reduced. The furnace is suitable for application and popularization.
Description
Art
Horizontal stirring wasted powder activated carbon regeneration furnace of the present invention belongs to chemical technology field, for after various medicine, food and the process of chemical products refinery decolorization and process organic wastewater after useless saturated Powdered Activated Carbon hot recycling.
Background technology
China reaches many ten thousand tons for the Powdered Activated Carbon amount of medicine, food and chemical products refinery decolorization every year, all does disposable products application, with rear useless saturated Powdered Activated Carbon or do garbage disposal, or does the substitute process of bunker coal.One ton of Powdered Activated Carbon is fired with more than 5 tons timber and is made with the process of chlorohydric acid pickling and neutralization &washing, owing to being filled poisonous and harmful substance in useless saturated Powdered Activated Carbon, be used as garbage disposal and severe contamination is brought to environment, even if when fuel substitute is disposed, because incomplete combustion also can pollutant atmosphere.Industrial production creates a large amount of useless saturated Powdered Activated Carbon on the one hand, and therefore pollute environment, and a large amount of industry high-concentration organic wastewater can not afford expensive powder electroless plating process economically on the other hand, a large amount of colourful organic wastewater flows into public waters, the health of harm the general common people.In fact various active carbon can and all should recycling utilization, regeneration expense is well below manufacturing expense, and realize recycling utilization, one ton of active carbon can play more than 8 tons and act on.Exist over a long time, from economy, environmental protection and resource circulation utilization all in the urgent need to being corrected in the unreasonable situation of this extreme backwardness of China.
Summary of the invention
Treat that wasted powder active carbon is extremely improper conducts oneself well the situation of putting over a long time to overcome, the invention provides a kind of Horizontal stirring wasted powder activated carbon regeneration furnace, utilize this regenerating furnace that the organic matter be adsorbed in wasted powder active carbon can be made to carry out 100 ~ 500 DEG C of orderly destructive distillation, desorb and thermal decomposition organic matters, then 600 ~ 850 DEG C and be oxidant with superheated vapour condition under, the organic matter carbon residue water-gasization remained in after destructive distillation in wasted powder active carbon removed, wasted powder active carbon just obtains regeneration and can recycle.
The technical solution used in the present invention is: it forms by regenerating Powdered Activated Carbon outlet, steel plate furnace shell, fireproof heat-insulating layer, stirrer paddle, shaft, oxygen rich air import, water vapour import, oxygen rich air distribution grid, oxidizing gas house steward, axle intermediate support, high-temperature shielding plate, shaft driving machine, useless burgy import, offgas outlet, furnace shell flange and drive sprocket etc.Be characterized in: shaft is established at the regeneration body of heater center that the steel plate furnace shell of supporting and fixing and fireproof heat-insulating layer are formed, shaft is bearing on body of heater two ends and axle intermediate support respectively, stirrer paddle is fixed by the blade securing member on shaft, and shaft is by drive sprocket and driving machine driven rotary; Polylith high-temperature shielding plate is set up vertically separately from high temperature to low temperature, barricade is made up of the stainless steel cloth of the high-temperature regeneration tail gas that can circulate, barricade lower end is embedded in powder layer of charcoal, in stove, high temperature naked light district establishes the very multiporous oxygen rich air distribution grid of multiple band, distribution grid is embedded in fireproof heat-insulating layer, above establish the oxidizing gas house steward of oxygen rich air import and water vapour import through furnace shell and oxygen rich air distribution grid through; Wasted powder active carbon enters body of heater low-temperature zone through the import of wasted powder active carbon, and the high temperature regeneration Powdered Activated Carbon after regeneration activating exports output by regenerating Powdered Activated Carbon, and regeneration tail gas is discharged by offgas outlet, goes to burn and Btu utilization.
Polylith high-temperature shielding plate is established in Horizontal stirring wasted powder activated carbon regeneration furnace of the present invention, axially multiple thermograde is formed at stove, the organic matter be adsorbed in useless charcoal is made progressively to complete evaporation and desorb along thermograde, thermal cracking produces organic matter carbon residue as few as possible, alleviates the load of activation to greatest extent.Powdered Activated Carbon mobility in high-temperature regeneration is fabulous, and the very low power of agitator of speed of agitator is very little.A large amount of water-gas that organic pollution containing destructive distillation generation in the tail gas of discharging and water-gas activation produce, so the tail gas of discharging carry out high-temperature burning and then Btu utilization.Utilize oxygen enrichment to be conducive to improving furnace temperature and energy-conservation as combustion adjuvant, the intervention of inert gas can be reduced to greatest extent, reduce the gas flow in regenerating furnace to greatest extent, prevent excessive gas flow rate from causing light and thin Powdered Activated Carbon and fly upward and bring loss and harm.The structural rate horizontal rotary regenerating furnace of this regenerating furnace is simple, cheap, is conducive to application and the popularization of wasted powder active carbon hot recycling.
