Abstract
The invention relates to a horizontal thermal regeneration furnace for waste powdered activated carbon, which belongs to the technical field of chemical equipment. The horizontal thermal regeneration furnace is used for activation and regeneration of the waste powdered activated carbon by superheated steam of 600-850 DEG C, and the horizontal thermal regeneration furnace comprises a horizontal rotating cylinder, which is supported in a refractory brick furnace body and is divided into multiple segments; a stainless steel wire mesh separating plate; an oxygen enrichment and gasification pure water distribution pipe; a waste powdered carbon inlet pipe; a regenerated powdered activated carbon overflow pipe; a tail gas pipe; a temperature regulating combustion chamber; a driving machine, and the like. In an ordered temperature gradient of a dry distillation segment, the waste powdered carbon with least organic carbon residue is prepared and deactivated; in an activation segment, rich oxygen is used as a combustion improver and the superheated steam is used as an activating agent, thermal regeneration conditions of high temperature and less tail gas amount in an activation region are produced, and the defect that tail gas whirls away the powder activated carbon for the reason of the large amount of tail gas can be reduced to a greatest extent, so that high quality and high yield regenerated powdered activated carbon can be obtained. The horizontal thermal regeneration furnace uses heat produced by organic matters in the waste powdered activated carbon and matrix carbon ablation at high temperature to complete the thermal regeneration without external fuel supply.
Description
Affiliated technical field
The present invention relates to the hot regeneratory furnace of a kind of horizontal wasted powder gac, belong to technical field of chemical, for the wasted powder gac heat regeneration after refining decolouring medication chemistry product.
Background technology
For a long time, various Powdered Activated Carbons are all used as disposable products application, refine the wasted powder gac after decolouring medication chemistry product or are used as rubbish or are used as fuel substitute.Powdered Activated Carbon is the same with granulated active carbon can be regenerated and be recovered absorption property and recycle by heat; but because not only carefully but also gently very easily flying upward characteristic, Powdered Activated Carbon seriously hindered hot regenerative operation; cause annual many ten thousand tons of wasted powder gacs all to become refuse; not only could not recycle, return on the contrary society and bring serious environmental pollution.Powdered Activated Carbon be take timber as raw material, and one ton of Powdered Activated Carbon will consume 5～10 timber and a large amount of heat energy, and one ton of Powdered Activated Carbon price is 1～1.50000 yuan.The colorful wastewater of many trade effluents, particularly dyestuffs industries, can not afford the Powdered Activated Carbon of inhaling look performance extra-heavy economically, the sea, great river that made a large amount of coloured toxic dye industrial wastewater pollutions.Powdered Activated Carbon can hot recycling utilization 8 times more than, and Powdered Activated Carbon is used as to disposable products application, is actually and is wasting natural products, and is destroying greening and waste resource, seriously runs counter to the rule of recycling economy.
Summary of the invention
In order to overcome, treat over a long time the imappropriate disposal situation of the wasted powder gac utmost point, the invention provides the hot regeneratory furnace of a kind of horizontal wasted powder gac, the organism that utilizes this regeneratory furnace can make to be adsorbed in wasted powder gac carries out 100～500 ℃ of desorb and thermolysiss in an orderly manner, then at 600～850 ℃ with take under the condition that overheated steam is oxygenant, the organism carbon residue water-gasization reaction remaining in after thermolysis in wasted powder gac is removed.The Powdered Activated Carbon of having removed after organism carbon residue has just obtained activation and regeneration.
The technical solution adopted in the present invention is: it is by the Powdered Activated Carbon discharge nozzle of regenerating, activation section rotation center pipe, activation section dead center pipe, refractory brick body of heater, swivel bearing wheel, oxygen enrichment and superheated vapo(u)r distribution pipe, temperature regulates combustion chamber, Stainless Steel Cloth dividing plate, bogie wheel drive shaft, horizontal rotary cylindrical shell, wasted powder gac input tube, tail gas water-gas mouth, charing section dead center pipe, charing section rotation center pipe, burning gas chimney, drive sprocket, driving machine, fuel gas outlet pipe, the compositions such as wasted powder gac import.Be characterized in: it is upper that rotary barrel is placed in the swivel bearing wheel being fixed in refractory brick body of heater, swivel bearing wheel under driving machine and drive sprocket drive driven rotary cylindrical shell to a direction rotation, rotary barrel is divided into multistage along its length, between every two sections, establishes Stainless Steel Cloth dividing plate, and former sections is low temperature (100～500 ℃) charing dry distillation area, and latter several sections is high temperature (600～850 ℃) activating and regenerating district, Jun She wide aperture, center, rotary barrel two ends and long rotation center pipe, in high-temperature activation district one sideway swivel pipe core, insert and be welded and fixed the activation section dead center pipe with DI with the regeneration Powdered Activated Carbon discharge nozzle of overflow port and many tiny oxygen enrichments and activation around thereof, in the one sideway swivel pipe core of char zone, insert the activation section dead center pipe that is welded and fixed wasted powder gac input tube, between rotation center pipe and dead center pipe, all establish O-ring seals, refractory brick body of heater is at the same with rotary barrel also corresponding a plurality of temperature adjusting combustion chamber and the fuel gas burner established of length direction, to regulate temperature and the additional heat of each section, wasted powder gac through the input of wasted powder gac input tube dehydrates through charing dry distillation area, after organism evaporation and thermo-cracking, make partial organic substances produce carbon residue and stay in wasted powder gac, be subject to the impact of material level, the wasted powder gac that contains carbon residue enters high-temperature activation district through dividing plate mesh, organism carbon residue in wasted powder gac carries out water-gas reaction at the high-temperature of the oxygen-enriched combusting generation of oxygen enrichment and the ejection of superheated vapo(u)r distribution pipe and the overheated steam of ejection, whole organism carbon residue water-gasization is removed, so wasted powder gac just obtains activating and regenerating, Powdered Activated Carbon after regeneration is discharged by the overflow port of regeneration Powdered Activated Carbon discharge nozzle.
The charing dry distillation area of the hot regeneratory furnace of wasted powder gac of the present invention and each section, activating and regenerating district burner hearth are all established temperature and are regulated combustion chamber, make to keep thermograde from low to high from dry distillation area to region of activation, make to be adsorbed on organism many as far as possible evaporations and desorb in retort section in wasted powder gac, reduce as little as possible organism thermo-cracking and produce organic carbon residue, reduce to greatest extent carbon residue and produce and the load of reduction region of activation.The water that injects activation section, through overheated and produce overheated steam, regulates flooding quantity and Rich Oxygen Amount can control the degree of depth of activation.Utilize oxygen enrichment to make ignition dope for air and can reduce to greatest extent gas flow in rotary barrel, in case the flying upward and losing of Powdered Activated Carbon, oxygen enrichment is also conducive to improve the temperature of region of activation.The activation tail gas that activating and regenerating process produces is the water-gas of high heating value, regulates the fuel of combustion chamber the unnecessary fuel gas done output except making temperature.
