Abstract

The utility model provides a noble metal recovering pyrolysis incinerator, which comprises incinerator furnaces, a gas mixing chamber, a secondary combustion chamber, a heat exchanger, a half-dry type absorption tower, an activated carbon storing tank, an air box type cloth bag dust remover, a spray washing tower, a fog water separator and a draft fan. The above-mentioned components are sequentially connected through a flue. The noble metal recycling pyrolysis incinerator in the utility model can effectively collect noble metal from metal trash for secondary applications. Waste gas generated during the whole incineration process will not be directly discharged to the outside. The pollution is thus reduced to the minimum. Meanwhile, by effectively separating the noble metal from metal trash by repeated incineration pyrolysis, the noble metal recycling pyrolysis incinerator can make the recovery rate of the noble metal further improved and contribute more economic benefits to enterprises.

Description

A kind of noble metal reclaims the pyrolytic incineration device

Technical field

The utility model belongs to burning back resource and reclaims the field again, specifically relates to a kind of device that noble metal in compound, active carbon or the mud is reclaimed by the pyrolytic incineration means.

Background technology

China is in the period of new and high technology develop rapidly, various new technologies, new material all are widely used, and has driven the big demand of rare metal, rare precious metal thus.But these metal materials will inevitably produce waste product, waste material and slag charge again in production, processing or use.If we reclaim these waste product waste residues and extract by technological means, not only can obtain considerable economic, and also have good social benefit.Present stage, the noble metal recovery technology is not also well developed, and also has deficiency aspect a lot, and low as the noble metal resource recovery, it is serious that regenerated resources not easy to be recycled or that economic worth is low abandon phenomenon.

Therefore, how setting up the rational apparatus for recovering metal of a cover is current urgent problem.

Summary of the invention

Goal of the invention: the purpose of this utility model is that at the deficiencies in the prior art providing a kind of can high efficiency reclaim noble metal, can make again simultaneously and pollute the recovery pyrolytic incineration device that reduces.

Technical scheme: a kind of noble metal that the utility model provides reclaims the pyrolytic incineration device, comprise incinerator, gas mixer, secondary combustion chamber, heat exchanger, the half dry type absorption tower, active carbon material stock groove, gas tank formula sack cleaner, spray scrubber, mist water separator and air-introduced machine, secondary combustion chamber, heat exchanger is connected by flue successively with half dry type absorption tower inlet, the outlet of half dry type absorption tower connects gas tank formula sack cleaner inlet by flue, the outlet of gas tank formula sack cleaner is connected by flue with the inlet of spray scrubber, the spray scrubber outlet is connected the inlet of mist water separator by flue, the outlet of mist water separator is connected by flue with air-introduced machine, described incinerator, gas mixer is connected by flue with secondary combustion chamber, adds active carbon material stock groove on the connection flue of the gentle box sack cleaner in half dry type absorption tower.

Wherein,, a plurality of incinerators can be set in order to improve the efficient of once burning,, take multistage to burn, guarantee the abundant decomposition of discarded noble metal.

Rubbish in the incinerator adds thermal control oxygen pyrolytic gasification in gas mixer chamber after, produce imflammable gas, this imflammable gas is imported into secondary combustion chamber, carries out the secondary high-temp combustion; Flue gas enters heat exchanger by secondary combustion chamber and cools off, and then enter the half dry type absorption tower, with alkali lye atomize chilling, neutralization, make flue gas at 600 ℃～200 ℃ temperature range chilling, can effectively prevent the regeneration of dioxin, and making flue gas through depickling, the place to go acidic materials enter pipeline through twice cooled smoke.

Flue gas after depickling enters that the dry type reaction unit further deacidifies again, sack cleaner is removed dust, after spray absorber further after the washing, enter atmosphere by air-introduced machine through chimney, whole vent gas treatment flow process is under the negative pressure state all the time to be moved.

Beneficial effect: the utility model can be collected out noble metal effectively and carry out the resource recovery from metal rubbish, the waste gas that produces in the whole burning process is through the absorption of device, not directly discharging to external world, it is minimum that pollution is reduced to, repeated combustion pyrolysis is simultaneously separated the noble metal in the metal rubbish effectively, and noble metal recovery rate is further enhanced.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment:

As shown in the figure, a kind of noble metal that the utility model provides reclaims and decomposes incinerator, comprise 2 incinerators 1, gas mixer chamber 2, secondary combustion chamber 3, heat exchanger 4, half dry type absorption tower 5, active carbon material stock groove 6, gas tank formula sack cleaner 7, spray scrubber 8, mist water separator 9 and air-introduced machine 10, incinerator 1, gas mixer chamber 2 and secondary combustion chamber 3 are connected successively by flue, secondary combustion chamber 3, heat exchanger 4 is connected by flue successively with half dry type absorption tower 5 inlets, 5 outlets of half dry type absorption tower connect gas tank formula sack cleaner 7 inlets by flue, on flue, be provided with 1 active carbon

material stock groove

6,7 outlets of gas tank formula sack cleaner are connected by flue with the inlet of spray scrubber 8, spray scrubber 8 outlet connects the inlet of mist water separator 9 by flue, and the outlet of mist water separator 9 and air-introduced machine 10 are connected by flue.

Incinerator 1 in the utility model mainly carries out high temperature pyrolysis to waste material and burns, and the organic principle in the waste material is removed; Secondary combustion chamber 3 is increased to 1100 ℃ with temperature, and further the long-chain compound that will not burn fully destroys, and guarantees to burn fully; Heat exchanger 4 is reduced to 550 ℃ with flue gas from 1100 ℃, can reclaim hot water or hot blast; Half dry type absorption tower 5 utilizes aqueous slkali that flue-gas temperature is reduced rapidly, prevents that two evil beautiful jades from generating between 200-500 ℃, utilizes the acid composition in the alkali lye absorption flue gas simultaneously; The fine solid particle that sack cleaner 7 is collected in the flue gas is guaranteed the dust qualified discharge.

A kind of noble metal that the utility model provides reclaims and decomposes incinerator; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications; for example add a plurality of incinerators etc.; these improvements and modifications also should be considered as protection domain of the present utility model, and all available prior art of each part not clear and definite in the present embodiment is realized.
