Background technology
Along with the development of China environmental protection work, substantial connection that is healthy and environment causes the extensive concern of society.Hazardous waste is one of important pollution sources of harm humans ecological environment and health, the material that China is listed in " National Hazard refuse register " has 49 kinds of large classes 498 kinds, because hazardous waste kind is many, Traits change is large, hazardous waste is before carrying out security landfill, usual needs take the refuse physicochemical property of certain process means to admission to control, and make its harmfulness be reduced, alleviate or eliminate.Curing/stabilizing is the important process means before hazardous waste enters security landfill field, particularly there is good stablizing effect for heavy metal waste, by curing/stabilizing, harmful refuse is fixed in a kind of fluid-tight matrix of inertia, refuse is after curing/stabilizing process, can poisonous and hazardous pollutant be changed into low-solubility, low migration and the metastable material of hypotoxic physics and chemistry character, the stable mechanism of curing technology is the Chemical bonding between refuse and coagulating agent, coagulating agent is to the physical inclusion of refuse, the effect that coagulating agent hydrated product is common to absorption of refuse etc., refuse is changed and forms tight solid, change the permeability of refuse, compressibility and intensity.
It is several that conventional curing technology mainly contains cement solidification, lime solidification, bitumen solidification and chemical stabilization etc., and different technical methods is applicable to different types of hazardous waste.Chinese patent application " a kind of hazardous waste solidification, stabilisation pretreatment system " (application number: 201320891873.7) disclose a kind of hazardous waste processing system; the engineering means that main employing separate unit mixer stirs realize the object of the curing/stabilizing of certain hazardous waste; during with the process of separate unit mixer; the hazardous waste that moisture content is higher often can be sticky on paddle; day output only has about 10t; and the test of finished product Leaching does not meet landfill requirement; must re-start solidification, treatment effeciency is low and effect is bad.At present, the domestic research to curing/stabilizing treatment agent is many, less to the research of complete set of equipments, is cured/stabilization processes for multiple types hazardous waste simultaneously, does not still have ripe complete production unit.
Summary of the invention
The purpose of this utility model is to provide a kind of raising treatment effeciency, can process the hazardous waste that multiple types, shape and Traits change are larger, hazardous waste two stirring curing/stabilizing treatment system that treatment effect is stable.
For achieving the above object, the utility model adopts following technical scheme:
A kind of hazardous waste is two stirs curing/stabilizing treatment system, the charging aperture of breaker is connected with the first waste storage metering and conveying device and the second waste storage metering and conveying device respectively with discharging opening, the second waste storage metering and conveying device, pre-mixer, connects with belt successively between homogenizer and device for discharging; Homogenizer and clear water are stored metering and conveying device, dose-storage metering and conveying device and powder material storing and conveying device and are connected with pipeline respectively; The absorption edge of dust collecting is arranged on above homogenizer and powder material storage metering and conveying device, and output is connected in dust process tapping equipment.
Described first waste storage metering and conveying device, the second waste storage metering and conveying device, clear water storage metering and conveying device, dose-storage metering and conveying device, powder material storage metering and conveying device are one or more sets respectively.
The beneficial effects of the utility model are:
1, the utility model system uses breaker to carry out fragmentation to the hazardous waste of large volume, solve Waste volume excessive do not enter mixer or to mixer cause damages, while stir process the also bad problem of effect;
2, the utility model system employs pre-mixer, the refuse of different water cut can be mixed, and ensures that moisture content is below 30%, stirs particle diameter simultaneously, the effect that when improving follow-up high-speed stirred, hazardous waste mixes with curing agent, stabilizing agent; The system day output of making can reach about 80t, and can be cured/stabilization processes by the hazardous waste larger to multiple types, shape and Traits change, and treating capacity and treatment effeciency are obtained for and significantly improve.
The Leaching concentration of the finished product 3, after the process of the utility model system all requires much lower than the landfill of " hazard waste landfill pollutant catabolic gene standard " (GB18598-2001).
