Achieve formerly: Green river of Hunan of a gentleman, hooligan is energy-saving platform of environmental protection cooperation
Guide language
The waste residue that contain mercury comes from chemical raw material to make, metallic mine is collected anthology, material of crude crude oil and natural gas exploitation, synthesis is made, batteries is made, illume appliance is made wait for an industry, mercuric content of these the waste residue that contain mercury are high, if inappropriate be apt to deals with, will pollute atmosphere, circumjacent soil, surface water and groundwater, the mercury in soil and its compound can enter human body through food chain, produce huge harm to human body. Because danger is abandoned,deal with cost is higher, how be located in manage, achieve investment cost of small, operation is low, deal with the effect that amounts to mark, make the pressing demand of experience mercuric industry. Via platform the autograph restricts application of VIP collaboration unit, platform organizes expert adviser to inspect communication for many times, think this technology handles a respect to undertake popularizing in the waste residue that contain mercury, have distinct advantage, send this announcement especially.
Note: The following data and data are offerred by the technology just offer, the data in providing square affirmatory article and data are not had by accident, for its authenticity in full charge.
One, trade current situation
The mill that abstracts illegally one
The mill that abstracts illegally 2
China is to look the amount to on preexistence bound still is not in more one of countries of mine mercuric mine, the mercury inside certain period will still be used continuously in industrial production. Bedding face of discharge capacity of Chinese mercury pollution is wide, bureau ground pollution is serious, especially mercuric mine mine and enterprise of nonferrous metal smelt and its periphery area, discharge mercuricly plus the industry such as coal fired power plant, also accentuated the mercuric pollution bear of area and global environment.
Because have the danger containing mercury of aptitude to abandon an enterprise to be located in the remote region such as Guizhou, Xinjiang and Ningxia more, certain business needs to pay big carry reach processing to deal with charge, process charge to escape dangerous trash, a few enterprises choose trash of illegal tip danger long-term perhaps keep in storage, this caused tremendous menace to place and circumjacent zoology environment.
Common mercury broken bits deals with method
1, roast law: To containing mercury waste residue uses direct roast processing, its high temperature heats make mercury volatilizes, classics condensation reclaims the metal is mercuric.
2, law of electrochemistry oxidation soak: Was to include the waste residue that contain mercury to add sodium chloride to make an oar electroanalysis soak, broken bits fluid is detached, soak fluid changes the part such as the processing that reach broken bits, its soak fluid oxidizes via changing the waste liquid after to be returned again to report groove is used circularly.
3, solidify fills bury processing law: Stability is changed and solidify reagent can produce chemistry with the mercuric contaminant with the medium waste residue that contain mercury or physics reacts, made translate into is not easy deliquescent, migratory ability the configuration with weak, smaller noxiousness. The product after solidify stability is changed is OK backfill or use at other utility.
4, ion exchange law: Carry through chemical dip in making mercury changes fluid posture, the method such as repass ion exchange reclaims mercuric.
2, technical brief introduction
1, deal with detached
Undertake the waste residue that contain mercury early days processing reserves, reserve stock undertakes dealing with departing, below high temperature condition, oxidation mercury decomposes the vapour that it is mercury and oxygen.
Hg + O2 of HgO →
Condensation of mercuric vapour classics reclaims get liquid state mercury, smelt broken bits enters broken bits field via cooling evacuation, analyse the composition in broken bits, the smelt residue that still contains other element having price stays wait for processing, accomplish danger to abandon deal with the resource of the process is changed, decrease quantify and harmless change.
2, tail gas sends to purify processing unit, undertake back row is put handling.
If plan institute is shown, the waste residue that contain mercury reclaims use craft to include deal with depart and tail gas purify processing two phase.
3, as comparative as other processing technology
1, compare with roast law photograph: The waste residue that contain mercury passes early days processing, raised follow-up mercury to reclaim rate, craft is simple, raw material adaptability is strong, the operation is simple, integrated benefit is better.
2, with electrochemistry photograph of oxidation soak law compares: Do not need to will contain dissolve of mercuric waste residue to enter the processing in fluid photograph, do not need to handle the liquid waste containing mercury after electroanalysising, do not need to add other drug, power consumption low cost is little.
3, fill the photograph that bury a law to compare with solidify: Raw material adaptability is strong, and the drug of solidify law and method, suit to contaminate soil at repair mercury commonly, do not suit to be changed at containing the stability of mercuric waste residue certainly, expensive drug raised cost.
4, compare with photograph of ion exchange law: Do not need to will contain dissolve of mercuric waste residue to enter the processing in fluid photograph, do not need to handle the liquid waste containing mercury after exchange, do not need to exchange colophony breed, reduced cost.
4, technical characteristic and advantage
This technology but efficient reclaim the metal in waste residue is mercuric. The waste residue of different to containing metal having price, can take metallic depart step, those who realize resource is integrated reclaim use. Handle to containing mercury danger to abandon and reclaim use be like advantage of lower part case:
1, technology of the distill after using pretreatment, technology is simple and sound, sufficient to containing mercury waste residue to undertake harmless change, resource is changed use, the mercury different pattern and valence condition all reclaims effectively use.
2, comfortable to the general of raw material sex is strong, be used former complementary makings cost is low;
3, technology maturity of advanced, craft, use turn operation continuously;
4, smelt broken bits can reclaim as resource use, extraction has price element;
5, sewage is used circularly discharge nothing more than, pay attention to environmental protection;
6, can accomplish resource to use the biggest change, processing of hydrosphere broken bits is harmless change and decrease quantify;
7, reduced danger to abandon collect, the environmental protection risk in keep in storage, carriage process;
5, successful case
Raw material: Contain mercuric acerbity mud
Reclaim child: Mercuric
Handle a technology: Igneous law handles technology
Handle project volume: Operation two years, year processing capability is 1200 tons
1, raw material origin
The mud of the acid that contain mercury that the waste material of firm of the danger that contain mercury of processing expects the process such as smelt of the zinc that it is lead, copper smelt, antimonial smelt arises.
2, technical brief introduction
This project uses mature high temperature distill to handle a technology, below constant pressure and condensing temperature, the mercury of more than 98% above is collected to come down by condensation, mercury reclaims rate is high. The contaminant that can ensure danger abandons the generation in handling a process discharges index to control standard of Home Yan Yuguo.
3, economic benefits
Mercuric content is in the waste residue that contain mercury 40% , one ton contains what mercuric waste residue passes this technology to reclaim deal with attainable the metallic mercuric product that makes an appointment with 396kg. In the meantime, the construction of this project and operation, effective settlement a large number of danger that contain mercury deal with uselessly problem, raising mercury to reclaim below the circumstance of rate, dangerous solid useless change is general industry firm to abandon.
