Description
Technical field
This utility model relates to a kind of organic hazardous waste plasma fusion gasification process system.
Background technology
Hazardous waste focuses on disposal options at present mainly has landfill and burns, and wherein organic hazardous waste is typically to burn.The general temperature of burning method, at 900 ~ 1000 DEG C, not only needs to consume a large amount of fuel, is also difficult to ensure that for the organic hazardous waste treatment effect containing difficult decomposed substances such as PCBs.Simultaneously, burning method can produce multiple secondary pollution, including flying dust, oxysulfide, nitrogen oxides, heavy metal and two English etc., current incineration technology heavy metal and the control effect of two English are limited, and along with the raising of environmental protection standard, the pressure that organic hazardous waste burns the secondary pollutant control produced is increasing.
Summary of the invention
For solving the problems such as low, heavy metal and two English control weak effect, resource for solution existing incineration technology process part organic hazardous waste treatment effeciency cannot recycle, the purpose of this utility model is to provide a kind of organic hazardous waste plasma fusion gasification process system.
The purpose of this utility model is achieved in that plasma gasification stove, waste heat boiler, chilling tower, sack cleaner, deacidification depurator, activated carbon adsorber are connected, and the air inlet of next equipment is received in the gas outlet i.e. going up an equipment;Wherein connecing nitrogen making machine and steam evaporator before plasma heating furnace respectively, and set overflow and slag mouth and furnace bottom heavy metal outlet, overflow and slag mouth is received in water-cooling groove;Deacidification depurator is the air inlet that desulfurizing tower is received in water pouring tower gas outlet.
Processing method is:
(1) being sent in plasma gasification melting furnace by the refuse being crushed to below diameter 5cm, melting furnace temperature controls, at 1300 ~ 1500 DEG C, to be passed through N in stove2As plasma medium gas and holding inert atmosphere, and in stove, it is passed through steam as gasifying agent;
(2) face, plasma melting furnace side sets overflow and slag mouth, and debirs gasify under anoxic conditions and melt, and the slag of weld pool surface is flowed out by overflow and slag mouth, enters water-cooling groove quenching and forms vitreous body;Plasma melting furnace bottom sets heavy metal outlet, heavy metal bigger for the proportions such as Fe, Cu is discharged;
(3) combustible gas that in plasma melting stove, gasification produces enters waste heat boiler and is cooled to about 500 DEG C, enters back into chilling tower and is cooled to 150 ~ 170 DEG C, subsequently enters sack cleaner and removes finely ground particle substance, enters back into deacidification depurator removing HCl, H2The sour gas such as S, through activated carbon adsorption, finally obtain the combustible gas after purification, with CO, H2It is main, can use as fuel.
The difficult decomposed substances such as compared with prior art, the beneficial effects of the utility model are: pyrolytic gasification under the conditions of high temperature, the PCBs that can fully degrade, and NOXGeneration concentration is low;Under the conditions of high temperature, two English can fully be degraded, and coordinates its regeneration of cooling suppression of chilling tower, and two English concentration of emissions are low;In refuse, heavy metal major part is solidificated in slag recovery, and small part is discharged after activated carbon adsorber adsorbs, and can effectively control;Generation combustible gas may utilize, thus reduces disposed of in its entirety cost.
Accompanying drawing explanation
Further illustrate this utility model below in conjunction with the accompanying drawings.
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Fig. 3 is the B portion enlarged drawing of Fig. 1.
Detailed description of the invention
Plasma gasification stove 1, waste heat boiler 2, chilling tower 3, sack cleaner 4, deacidification depurator 5, activated carbon adsorber 6 are connected, and the air inlet of next equipment is received in the gas outlet i.e. going up an equipment;Wherein connecing nitrogen making machine and steam evaporator before plasma heating furnace respectively, and set overflow and slag mouth 11 and hearth deslagging mouth 13, overflow and slag mouth is received in water-cooling groove 12;Deacidification depurator is the air inlet that desulfurizing tower 52 is received in water pouring tower 51 gas outlet.
Processing method is:
(1) organic hazardous waste is crushed to below 5cm;
(2) start plasma fusion gasification furnace, be passed through N2Keep inert condition, keep melting furnace temperature about 1300 ~ 1500 DEG C, will broken after refuse sent in plasma gasification melting furnace by dog-house 14, and be passed through part steam as gasifying agent, carry out melted pyrolytic gasification;
(3) the organic decomposes in refuse, and react with steam, carry out pyrolytic gasification;Heavy metal and lime-ash at high temperature form molten state body, and weld pool surface molten mass is flowed out by overfall, enter water-cooling groove quenching and form vitreous body;Part heavy heavy metal such as Fe, Cu etc. are periodically discharged by bottom slag discharge, and cooling is reclaimed;
(4) refuse pyrolytic gasification under the conditions of high temperature, two scruple solution ultrahigh in efficiency, NOXGeneration concentration is low;Heavy metal major part can be cured in slag, and the amount discharged with combustible gas is less than incineration treatment technology;
(5) combustible gas that debirs gasification produces enters waste heat boiler and is cooled to 500 DEG C, enters back into chilling tower and is chilled to 150 ~ 170 DEG C, prevents two English regeneration;After chilling tower is discharged, enter sack cleaner remove finely ground particle substance;After dedusting, combustible gas enters deacidification depurator, and deacidification is divided into two-stage, the first order to drench tower at water, drenches tower water flowing to water, washes removing HCl with water, and is cooled to less than 100 DEG C, produces dilute hydrochloric acid and reclaims, and the second level, at desulfurizing tower, adds Fe to desulfurizing tower2O3Desulfurizing agent and water, remove with H2S is main organic sulfur compound, produces Fe2S3Reclaim;Combustible gas after deacidification enters back into activated carbon adsorber, and in further absorption tail gas, the heavy metal such as Hg, Pd, finally discharges utilization;Through activated carbon adsorption, finally obtain the combustible gas after purification, with CO, H2It is main, can use as fuel.
