Abstract
A precious metal recovery device for waste liquid incineration comprises a storage tank which is arranged horizontally and inclines upwards by 15 degrees. An upright incineration tower and an upright scrubber tower are arranged on the side wall of the top end of the storage tank side by side. The bottom end of the incineration tower and the bottom end of the scrubber tower are both communicated with the storage tank. The incineration tower comprises a tower drum. The top end of the tower drum is sealed. The tower drum is divided into an upper combustion section and a lower splat cooling section. A waste liquid air inlet pipeline is arranged on the side wall of the middle of the combustion section. An atomization spray pipe is arranged on the side wall of the splat cooling section. Gas-state sufficient combustion is achieved, internal nitrogen, phosphorus and chlorine which are complex in component and low in content are treated better, a solvent is prepared by fully using high heat, fuel consumption is reduced, and the low loss rate of precious metal is guaranteed.
Description
Technical field
The present invention relates to noble metal and reclaim field, particularly relate to liquid waste incineration and reclaim precious metal device.
Background technology
Environmental protection treatment refuse, burning is an important process.Containing the noble metal needing to reclaim in waste liquid, it is also a kind of normality of the dead catalyst containing noble metal.Both combine, and are exactly while recovery noble metal, dispose the process of organic liquid waste.
Waste liquid containing noble metal mostly is organic solvent and mostly is hydrocarbon, and molecular structure is C
xh
yo
z,part medical waste contains a small amount of medicine intermediate, nitrogenous, chloride, partial chemical waste liquid is phosphorous, containing iodine; But Main Ingredients and Appearance is all nytron key.Total feature is exactly that calorific value is very high, and have the composition that trace is very assorted, it is little that neat liquid form exists, and solid-liquid mixes, and depends on carbon carrier.This waste material, generally all takes burning disposal.At present, for the solidliquid mixture of this carbon carrier, adopt distillation much pretreated, distillation test residue and a small amount of distillate burning disposal in solid form.
For burning process, designer knows that the burning under gaseous state is the most abundant, is exactly solid-state refuse, is also under the state adopting secondary burning gaseous state, Thorough combustion.The burning disposal of prior art is not thorough, and burning is abundant not, haves much room for improvement.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of with gaseous state Thorough combustion, by the complicated of the inside, the nitrogen that content is not high, phosphorus, chlorine process better, make full use of high heating value and obtain solvent, the consumption of fuel saving, ensures that the liquid waste incineration of the low loss late of noble metal reclaims precious metal device.
For realizing the object of the invention, provide following technical scheme: liquid waste incineration reclaims precious metal device, it is characterized in that comprising horizontal drain and the 15 degree of storage tanks arranged that are inclined upwardly, tank roof side wall is set side by side with burning tower straight up and aeration tower, burn tower to be all communicated with storage tank with aeration tower bottom, described burning tower comprises tower cylinder, tower cylinder end sealing, tower cylinder is divided into the burning zone on top and the quench zone of bottom, burning zone stage casing sidewall is provided with waste liquid admission line, quench zone sidewall is provided with atomizing spray pipe, aeration tower comprises tower cylinder, tower cylinder nearly top sidewall is provided with circulating water intake, the storage tank bottom end that is inclined upwardly is provided with dosing mouth, dosing mouth connects medicine system, medicine system comprises the drug feeding pipeline be connected with dosing mouth, the dispensing canister be connected with drug feeding pipeline, described drug feeding pipeline is provided with filter and circulating pump, storage tank other end bottom arranges vacuum lead, vacuum lead connects vacuum filter and vacuum pumping pump, circulating water intake arranges pipeline and connects circulating pump.
As preferably, described waste liquid admission line comprises body, and body one end is provided with end plate, end plate is provided with wind-supplying mouth, atomization waste liquid port and combustion-supporting gas port, body central is provided with conical jet pipe, and playpipe stretches out from body other end end plate, stretches in burning zone.
As preferably, in aeration tower tower cylinder, interleaved is provided with dividing plate from the top down.
Beneficial effect of the present invention: the embodiment of 1 security aspect, organic solvent volatility is very strong, inflammable; Waste containing noble metals solid-liquid mixes, and when burning, is not easy control temperature, when heating low-temperature zone, controls bad, and gas ratio controls bad, easily fires.Fluid separation applications out, directly burn, safety.
2 energy-conserving and environment-protective, under pressurizing atomizing state, after direct and combustion adjuvant air fully mixes, directly light, sufficient combustion, clean tail gas.Make full use of the heat of waste liquid self, fuel saving.After quench spray, all salt and noble metal, all in water.After vacuum filtration, after again burning as solid, hand over lower end operation to refine, water circulation use, does not have discharge of wastewater.Device can use with the series connection of solid stove, serves as dual firing chamber and the vent gas treatment of solid combustion stove, saves device fabrication cost.
