Description
Technical field
The utility model relates to that a kind of Hazardous wastes solidifies, stabilization pretreatment unit, particularly in a kind of can second stage employ wet refuse the Hazardous wastes of waste water solidify, stabilization pretreatment system.
Background technology
Pre-treatment is the pre-treatment step of dangerous solid waste security landfill.Hazardous wastes security landfill is generally regional danger and centrally disposes facility, the Hazardous wastes kind of receiving many, proterties difference is large, most Hazardous wastess cannot meet the requirement of security landfill field to the direct landfill of refuse, landfill must take certain preprocessing means to control admission refuse proterties before disposing, be refuse after pre-treatment, hazardness is reduced, alleviates or eliminates, meet " hazard waste landfill pollution control criterion " (GB18598-2001) in refuse admission standard.
The many kinds of measures such as Hazardous wastes pre-treatment counting comprises, fragmentation, neutralization, redox, curing/stabilizing.Wherein curing/stabilizing is counted owing to having the features such as treatment effect is stable, treating processes is simple, processing costs is cheap, and is widely used in the preprocessing process of Hazardous wastes.The curing/stabilizing method adopting at present both at home and abroad mainly contains: cement solidification, lime/flyash solidify, plastic material solidifies, chemical stabilization etc.Different method of counting is used in different refuse kinds, and such as chemical stabilization counting is main to be used and be suitable for the multiple refuse such as heavy metal, non-heavy metal etc. with heavy metal class refuse, cement solidification.
The treatment facility mud larger to water content in prior art, as broad as long treat but directly solidify, when processing, be easily bonded on the machine wall of stirrer, if carry out in advance processed, process the sewage taking off, more loaded down with trivial details again, efficiency is not high.In addition when existing dangerous solid waste pre-treatment machine is processed, easily produce dust, noise is very large, environmental protection not.
Utility model content
The purpose of this utility model is while solving the larger sludge treatment of above-mentioned prior art water content, easily be sticky on mixer wall and affect efficiency, if dehydration in advance needs again to process the effluent problem producing, provide a kind of Hazardous wastes solidify, stabilization pretreatment system, this device can be by the sewage secondary utilization in wet mud, can directly not stir wet mud, not need again to process the sewage of the wet sludge creation of dehydration.
The Second Problem that the utility model solves is dust, the not problem of environmental protection of easily producing while solving existing dangerous solid waste pre-treatment machine processing.
The technical scheme that realizes the utility model object is: a kind of Hazardous wastes solidifies, stabilization pretreatment system, comprise refuse storage metering conveyor, water storage metering and conveying device, medicament storage metering and conveying device powder material storage metering and conveying device, stirrer; In refuse storage metering conveyor, be also provided with one or more wet dewatering of waste machines, with the sewerage recovering box being connected with wet dewatering of waste machine, sewerage recovering box is connected in stirrer.
Above-mentioned refuse storage metering conveyor is also provided with one or more sets dust and reclaims storing device, comprises blower fan and the dust collection box being attached thereto.
Above-mentioned Hazardous wastes solidifies, stabilization pretreatment system, and described refuse storage metering conveyor is one or more sets.
Above-mentioned Hazardous wastes solidifies, stabilization pretreatment system, and described powder material storage metering and conveying device is one or more sets.
Refuse storage metering conveyor, medicament storage metering and conveying device, powder storage metering and conveying device, sewerage recovering box are connected with stirrer.Water storage metering and conveying device is connected with medicament storing device with stirrer, and automatic control device is connected with each device by gas circuit, realizes electrical automation control.
Hazardous wastes curing/stabilizing pretreatment system, wherein drug metering e Foerderanlage is connected with water storage metering and conveying device, and sewage reclaims torage tank and is connected with stirrer, makes sewage can enter stirrer and serves as normal water and use.The number of powder metering transfer roller arranges as required, if often use multiple powder, as flyash, cement, lime etc., is separately positioned in a powder conveyer.Fly-ash separator is connected with refuse storage metering and conveying device, and the flying dust producing in adition process is absorbed, and is all transported in dust storer.
When the operation of suite of equipment system:
1. dewatered sludge state (humidity is below 30 ﹪) is first sent into refuse, all kinds of powder material, medicament and water stirrer from depository separately respectively after metering.Stirrer is received after a certain amount of refuse, stops adding.In stirrer, material proportion carries out mix and blend after completing.Mix and blend, reacted material are discharged by the upset dumping device of stirrer, accepted and transport by transport trolley below stirrer.
2. wet mud state (humidity is more than 30 ﹪) is first poured refuse in sludge dewatering equipment into, and wherein moisture is de-enters in stirrer to a certain extent, adds all kinds of powder materials, medicament to send into after metering stirrer from depository separately respectively.Stirrer is received after a certain amount of refuse, stops adding.In stirrer, material proportion carries out mix and blend after completing.Mix and blend, reacted material are discharged by the upset dumping device of stirrer, accepted and transport by transport trolley below stirrer.
3. dewatered sludge and wet mud both have, and dewatered sludge is put into mud hopper, and the mud that simultaneously wets is put into sludge dewatering equipment and dewatered, and the sewage taking off is stored in device for recycling sewage.Add all kinds of powder materials, medicament and sewage to send into after metering stirrer from depository separately respectively.Stirrer is received after a certain amount of refuse, stops adding.In stirrer, material proportion carries out mix and blend after completing.Mix and blend, reacted material are discharged by the upset dumping device of stirrer, accepted and transport by transport trolley below stirrer.Now wet sludge dewatering completes, and adds in stirrer, proceeds to stir as the step in 2, adds dewatered sludge at the same time, with this repeatedly in mud drain hopper.
The utlity model has positive effect:
(1) dust distributing in the utility model device operational process traps, and dust content in whole service environment is greatly reduced, and the pollution of environment is reduced greatly.(2) due to the existence of the sludge dewatering equipment adding, make mud can ensure to stir the in the situation that of certain ridity, and the sewage taking off can utilize again, serve as additive in whipping process, fully mix with cement, so just greatly strengthened practicality, improved utilising efficiency, reduce the processing again of sewage, saved processing cost and improved efforts at environmental protection quality.
