Description
Technical field
The utility model belongs to incineration treatment of garbage field, and in particular to one kind is used for incineration of refuse flyash stabilization processes
Grey medicine homogenising system.
Background technique
In recent years, waste incineration and generating electricity industry in China's is fast-developing.Incineration method gradually substitutes traditional landfill method, becomes
The first choice of Urban Garbage Treatment in China Project Technical route at present.Waste incineration handles Domestic Waste Minimization in realization same
When, flying dust can be generated, flying dust yield accounts for about the 3%~5% of full factory's quantity of refuse burning disposal amount.Since flying dust is enriched largely
The poisonous and harmful substances such as heavy metal were classified as hazardous waste, the recycling of flying dust by " National Hazard waste register " in 2016
Using being more restricted, incineration of refuse flyash has to pass through stabilization processes, the nuisances such as heavy metal that flying dust Central Plains is enriched with
Matter stabilizes, and leachate pollutant concentration meets relevant national standard, just can enter landfill yard landfill.
The mainstream technology of country's waste incineration industry processing stabilizing fly ashization processing at present is chelating agent stabilisation+cement
Curing process.Wherein, chelating agent stablizes the most critical link for turning to incineration of refuse flyash processing, and the quality of chelate effect is straight
Connect the stabilization processes effect that decide to heavy metal in flying dust.In processes, usually by chelating agent, water and flying dust by certain ratio
Example is being kneaded progress ash in blender-medicine mixing and chelatropic reaction.In addition to the property of chelating agent itself works, flying dust and chelating
Agent solution also determines chelate effect in the mixing uniformity being kneaded in blender.Traditional only one chela of mixing blender
Mixture solution inlet port, chelating agent solution are inputted from one end into body, easily cause input end chelating agent liquid more in kneading machine,
Tail end feed liquor is few, and flying dust stirs unevenness, to be easy to cause the leachate pollutant concentration index of flying dust after stabilized processing
It is unqualified.
Utility model content
The utility model aim is: in view of the above problems, providing a kind of for incineration of refuse flyash stabilisation
The grey medicine homogenising system of processing solves the problems, such as that chelating agent solution mixes unevenness with flying dust, guarantees that chelating agent solution is burnt with rubbish
It burns flying dust and is being kneaded full and uniform mixing in blender, improve the effect of incineration of refuse flyash stabilization processes.
The technical solution of the utility model is as follows:
A kind of grey medicine homogenising system for incineration of refuse flyash stabilization processes, including be kneaded blender, lower ash system,
Chelating agent solution delivery pump and liquid distribution trough, the mixing blender upper end offer a flying dust entrance and several chelatings
Agent solution entrance is kneaded in blender and is equipped with two spiral shape agitating shafts, and the agitating shaft is driven by motor, and is kneaded blender
Lower end offers discharge port；The delivery pump is connect by pipeline with liquid distributor inlet, and the liquid distributor outlets are logical
It crosses several pipeline branches and is connect with the chelating agent solution entrance for being kneaded blender, the lower ash system is by lower grey channel and flies
Grey entrance connection.
Further, the quantity of the chelating agent entrance is 3, and the chelating agent entrance is equidistant in mixing blender upper end
From distribution.It is usually solid-state like with certain moisture content after flying dust, chelating agent and water mixing, therefore the mixing with fluid substance
It compares, to realize the character substance is mixed with certain difficulty.By single chelating agent solution entrance is changed in the prior art originally
The form that multiple entry enters is both that traditional uniaxial stirring is changed to Double shaft stirring, is conducive to increase connecing for chelating agent and flying dust
Contacting surface product, improves mixed effect.
Further, the pipeline branch road of the liquid distributor outlets is provided with volume control device, the flow control
Device processed includes regulating valve and fluid flowmeter.The inlet of chelating agent is controlled by volume control device, so that chelating agent
It measures and matches with the inlet of flying dust.According further to the setting position of flying dust entrance, the chela far from flying dust entrance can be suitably reduced
The inlet of mixture entrance, so that the substance distribution in whole system is more uniform.
Further, the chelating agent entrance is provided with spray head.Chelating agent can be more uniformly sprayed at mixed by spray head
It refines in blender.
Further, multiple groups stirring blade, and the paddle on two agitating shafts are evenly arranged on the agitating shaft
Piece installation site mutually staggers.Reinforce mixing effect by adding stirring blade, the stirring blade on two agitating shafts is installed
Position mutually staggers to avoid interfering between each other.
Further, the inner bottom of the cylinder for being kneaded blender is reclinate arcwall face, and the discharging
Mouth is located at the center position of arcwall face.It is kneaded the cylindrical shape of blender, by optimization convenient for discharging.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are: adding and optimizing chela
Quantity, distribution and the structure of mixture solution inlet increase the agitating shaft being kneaded in blender and stir provided with what is mutually staggered
Blade is mixed, setting volume control device has advanced optimized the additional amount and distribution situation of chelating agent, improved by the above measure
The mixed effect of chelating agent solution and flying dust so as to reduce the dosage of chelating agent improves economic benefit；Pass through optimization
The cylindrical shape for being kneaded blender facilitates discharging to improve working efficiency.
