Description
Technical field
The invention belongs to resource reclaim field of comprehensive utilization, be specifically related to the retrieving arrangement of precious metal in a kind of waste catalyst.
Background technology
In the industrial and agricultural productions such as iron and steel, chemistry, special material, the consumption of common metal is huge, and in the last few years, the comprehensive utilization of China's pay attention to day by day first resource and the research and development of open pit mining, particularly paid close attention to from the research and development containing waste catalyst recovery valuable metal.But compared with abroad, China utilizes the level of secondary resource still to have larger gap.
But along with demand increase while, metal can expected reserves continuous decrease.Meanwhile, containing the quantity of precious metal waste also in continuous growth, therefore carry out reclaiming the pressure that can alleviate metal reserves and decline to these wastes, also can reduce the huge Environmental costs that waste brings.It is a kind of common recovery method that chemistry drop is got, and the normal sequestrant used is ethylenediamine tetraacetic acid (EDTA) (EDTA) and sodium salt quasi-chelate compound thereof, and this sequestrant is strong to the sequestering power of metal ion, just has good drop to get efficiency.But this sequestrant is difficult to be degraded in physical environment, this quasi-chelate compound is used to bring Secondary Organic to pollute therefore for a long time, in a large number.
N, N'-ethylenediamine disuccinic acid be a kind of in physical environment degradable sequestrant, be applied to drop at present and fetched earth heavy metal ion in earth.
Summary of the invention
The present invention proposes the retrieving arrangement of precious metal in a kind of waste catalyst, this device can use tackiness agent that useless ink powder, spent catalyst are integrated together granulation, then carry out destructive distillation, obtain empyreumatic oil, provide pre-treatment for spent catalyst carries out precious metal regeneration.Produce empyreumatic oil in retort process to use as regenerated fuel, producing carbonization gas can act directly in gas retort as fuel, produces the raw material of destructive distillation slag as spent catalyst recover precious metals.Utilize eco-friendly N, N'-ethylenediamine disuccinic acid sequestrant, in autoclave treater, got containing the palladium composition in palladium waste catalyst by chemical drop.
The retrieving arrangement of precious metal in waste catalyst of the present invention, its concrete structure is by the stirred pot of mixture; And be arranged at stirred pot top, for adding the material inlet of raw material; The whipping appts for stirring material is also provided with in the inner chamber of stirred pot; The lower side of stirred pot is connected with the transport unit for transmitting material; Stirred pot is connected with tablets press by transport unit; Tablets press is connected with destructive distillation device by transport unit; The vertical direction of destructive distillation device is provided with screening machine, is sprinkled upon in continuous retorting device for being spread uniformly by the raw material made; Raw material after destructive distillation; Add in autoclave treater by transport unit; The top of autoclave treater arranges material mouth; The bosom of autoclave treater is provided with agitator; Autoclave treater is connected by pipeline with filter, storage tank and withdrawing can; The sidepiece of storage tank is provided with the fluid inlet for adding pH value adjustment liquid.
The device of recovery discarded metal catalyzer of the present invention, easy and simple to handle, save manpower and low-consumption high-efficiency, have a good application prospect.
Accompanying drawing explanation
Fig. 1: the retrieving arrangement schematic diagram of precious metal in waste catalyst: wherein,
1. stirred pot; Material inlet 11; Whipping appts 12; Transport unit 2; Tablets press 3; Screening machine 41; Destructive distillation device 4; Autoclave treater 5; Material mouth 51; Agitator 52; Filter 6; Storage tank 7; Fluid inlet 71; Withdrawing can 8.
Embodiment
The following examples will be further described the present invention, but not thereby limiting the invention.
After taking raw material (150kg spent catalyst, 19kg give up ink powder, 14kg clay and 15kg water), to be given up ink powder and spent catalyst, add in stirred pot 1 by material inlet 11, slowly stirred 20 minutes by whipping appts 12, fully after mixing, then add clay and water by material inlet 11, continue to puddle evenly, by the transport unit 2 that stirred pot 1 bottom connects, material is sent to tablets press 3 granulation, the diameter of pellet is between 5 ~ 7cm; Material granulation completed, to be spread the raw material made uniformly by screening machine 41 and is sprinkled upon in continuous retorting device 4, ensure furnace bottom all to cover, and to prevent local dry burning from causing body of heater to damage, destructive distillation is carried out in sealing subsequently; Start heat temperature raising, after rising to 450 DEG C from room temperature, be incubated 2.5 hours, stop heating, treat that temperature is down to room temperature from 450 DEG C and is come out of the stove, forbid directly to lower the temperature with water; Raw material after obtained destructive distillation; By raw material after 50kg destructive distillation; Add in 100L autoclave treater 5 by transport unit 2, the material mouth 51 arranged from autoclave treater 5 top, drop into 5kgN, N'-ethylenediamine disuccinic acid, the agitator 52 opening autoclave treater 5 stirs with 300 revs/min of speed, and be warming up to 60 ° of C, process after 1.0 hours, liquid is filtered through filter 6 by pipeline, after liquid cooling but to be filtered, through piping by filtrate pump to storage tank 7, add dilute sulphuric acid from the fluid inlet 71 of storage tank 7, make pH value be adjusted to 4, after static 0.5 hour, to separate out N, N'-ethylenediamine disuccinic acid pumps into withdrawing can 8.
Metal ion-N, N'-ethylenediamine disuccinic acid chelating systems after acidifying discharge palladium ion concentration analyzed by icp ms.The device of recovery discarded metal catalyzer of the present invention, easy and simple to handle, save manpower and low-consumption high-efficiency, have a good application prospect.
