Description
Technical field
Precious metal device is reclaimed the present invention relates to noble metal recycling field, more particularly to liquid waste incineration.
Background technology
Environmental protection treatment waste, burning is an important process.Contain the noble metal of recovery in need in waste liquid, be also that your gold contained
A kind of normality of the dead catalyst of category.Both combine, and are exactly while noble metal is reclaimed, to dispose the process of organic liquid waste.
Waste liquid containing noble metal is generally organic solvent mostly hydrocarbon, and molecular structure is CXHYOZ,Part medical waste
Containing a small amount of medicine intermediate, nitrogenous, chloride, part chemical waste fluid is phosphorous, containing iodine；But Main Ingredients and Appearance is all
Nytron key.Shared feature, is exactly that calorific value is very high, has micro very miscellaneous composition, it is seldom that neat liquid form is present, and solid-liquid is mixed
Close, depend on carbon carrier.This waste material, typically all takes burning disposal.At present, for the solidliquid mixture of this carbon carrier, adopt
It is many with distillation pretreatment, distillation test residue and a small amount of distillate burning disposal in solid form.
For burning process, the burning that designer is both known about under gaseous state is most abundant, is exactly the waste of solid-state,
It is, using in the state of secondary burning gaseous state, fully to burn.The burning disposal of prior art is not thorough, burns not abundant enough, has
It is to be modified.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides one kind is fully burnt with gaseous state, the composition of the inside is answered
Miscellaneous, it is more preferable that the not high nitrogen of content, phosphorus, chlorine are handled, and makes full use of high heating value to obtain solvent, saves the consumption of fuel, it is ensured that your gold
The liquid waste incineration for belonging to low loss late reclaims precious metal device.
To realize the object of the invention, there is provided following technical scheme：Liquid waste incineration reclaims precious metal device, it is characterised in that
Burning tower straight up is set side by side with storage tank including horizontal drain and the 15 degree of settings that are inclined upwardly, storage tank tip side wall
And aeration tower, burn tower and aeration tower bottom is connected with storage tank, the burning tower includes tower, tower end sealing, tower
It is divided on the burning zone on top and the quench zone of bottom, burning zone stage casing side wall and is provided with waste liquid admission line, quench zone side
Wall is provided with atomizing spray pipe, and aeration tower includes tower, and the nearly tip side wall of tower is provided with circulating water intake, and storage tank is inclined upwardly
End bottom is provided with dosing mouth, and dosing mouth connection medicine system, medicine system includes the drug feeding pipeline being connected with dosing mouth and added
Filter and circulating pump are provided with the dispensing canister of pencil road connection, the drug feeding pipeline, storage tank other end bottom, which is set, takes out true
Vacant duct, vacuum lead connection vacuum filter and vacuum pumping pump, circulating water intake set pipeline to connect circulating pump.
Preferably, the waste liquid admission line includes body, body one end, which is provided with end plate, end plate, is provided with benefit wind
Mouth, atomization waste liquid port and combustion-supporting gas port, body central are provided with conical jet pipe, and playpipe is stretched from body other end end plate
Go out, stretch into burning zone.
Preferably, interleaved is provided with dividing plate from the top down in aeration tower tower.
Beneficial effect of the present invention：Embodiment in terms of 1 security, organic solvent volatility is very strong, inflammable；It is useless containing noble metal
Expect solid-liquid mixing, when burning, it is not easy to control temperature, when heating low-temperature zone, control is bad, and gas ratio is controlled not
It is good, easily fire.Liquid is separated, directly burnt up, safety.
2 energy-conserving and environment-protective, under pressurizing atomizing state, after direct and combustion adjuvant air is sufficiently mixed, directly light, burn
Fully, clean tail gas.The heat of waste liquid itself is made full use of, fuel is saved.After chilling spray, all salt and noble metal, all
In water.After vacuum filter, after being burned again as solid, lower end process is handed over to refine, water circulation use, without discharge of wastewater.
Device can be used in series with solid stove, serve as dual firing chamber and the vent gas treatment of solid combustion stove, save device fabrication cost.
