Description
Affiliated technical field
The present invention relates to the clean-out system that ceramic filtering plate is cleaned on the ceramic filter.
Background technology
Ceramic filter is a capillary principle of utilizing ceramic capillary, and-------permeable airtight and solid-liquid separating equipment of design, the ceramic capillary size is generally at 0.1～10um.In the production use, filter cake is adsorbed on the ceramic filtering plate surface, and filtrate is sucked away by the ceramic filtering plate micropore.The reciprocation cycle of process like this, in micropore, form chemical fouling and machinery obstruction (depositions such as particle and glutinous mud) inevitably, though this equipment design nitric acid cleaning, ultrasonic cleaning and water purification back-purge system, and used once in per 8～10 hours, but to different filtering objects, blockage problem still often takes place, at least less than one month, less than 1 year, discard because of stopping up fully at most once the cover ceramic filtering plate.So just problem that the article of a piece " cleaning practice of ceramic filter and discussion " by name of the 24th phase the 1st volume 34-37 page or leaf publication of publishing " mining metallurgical engineering " in February, 2004 is discussed.In incomplete obstruction process, throughput of filtration has been subjected to very big influence, and more transducer set ceramic filtering plate expense is also very expensive, more than 5000 yuan of average every square meter.
The obstruction of ceramic filtering plate has not only increased running cost to the user, simultaneously the market development of manufacturing enterprise and the widespread use of this energy-conserving and environment-protective equipment all has been subjected to serious restriction.Also just because of this reason, at present international and domestic ceramic filter equipment manufacturers all sell by test and Selection ground the user of need solid-liquid separation.
Summary of the invention
The purpose of this invention is to provide a kind of clean-out system that is used for cleaning ceramic filtering plate, ceramic filtering plate is cleaned, the micropore of mediation ceramic filtering plate is to recover filtering function.
A kind of clean-out system that is used for cleaning ceramic filtering plate of the present invention, it is to comprise the aqueous solution that weight percent content is 0.1～5% nitric acid, 0.1～5% hydrochloric acid, 0.2～3% hydrofluoric acid, 0.1～5% oxalic acid.
The present invention utilizes the powerful corrodibility of " chloroazotic acid " of nitric acid and hydrochloric acid composition, in order to remove carbonate, incrustation scale, and other metallic compound such as iron dirt, patina, aluminium rust etc. had good solvency action, also help many oxidation operations, decomposition in the dirt.Be equipped with hydrofluoric acid, can remove silicon dirt and iron dirt better.Because ferric oxide is Fe especially
3+Low with nitric acid, hydrochloric acid and hydrofluoric acid speed of reaction under lower concentration, form difficult filtering floss, stop up the micropore of filter plate in order to prevent the floss that clean-out system occurs in reaction again, be added with oxalic acid in the clean-out system, strengthen ferric oxide by its sequestering action, especially Fe
3+Dissolving.Therefore, this clean-out system can clean the ceramic filter filter plate of the pulp dewatering that is applied to metal mine preferably, and the dirt on such ceramic filtering plate mainly is pore forming material in sulfide, oxyhydroxide, carbonate, silicate and the beneficiation reagent, flocculation agent, glutinous mud etc.
For the wetting ability that strengthens in the clean-out system acid, stablize the dirty ability of clean-out system decontamination in the cleaning process and to the corrosion inhibition of steel, also include weight percent content in the clean-out system of the present invention and be the buffering component of the sodium-chlor of 0.05～1% ammonium bifluoride and/or 0.1～2%.
Because tamper mainly is present in the micropore of filter plate, in order to improve cleaning performance, should add suitable permeate agent in the clean-out system,, is convenient to clean-out system and contacts in dirt to improve the perviousness of medicament.The inventor finds also that under study for action the obstruction of ceramic filtering plate also has the factor of microorganisms such as bacterium except ore pulp particulate matter factor.In the inherent filtration procedure of the micropore of ceramic filtering plate, easily microorganisms such as breed bacteria, algae are accelerated the obstruction of its micropore, therefore, in clean-out system, add permeate agent, also help bacterium, algae, the sterilization of glutinous mud, the effect of dissolving and peeling off are made the cleaning performance multiplication with germicidal action.The present invention selects for use hydrogen peroxide, dodecyl dimethyl benzyl ammonium bromide to make permeate agent, can add wherein one or both, and its weight percent content is: hydrogen peroxide: 0.02～2%; Dodecyl dimethyl benzyl ammonium bromide: 0.005～1%.
In order to reduce the surface tension of clean-out system, improve that it is wetting, the ability of dispersion, emulsification, solubilising, also be added with anion surfactant in the clean-out system of the present invention, select acid resistance one or both of sodium lauryl sulphate, Sodium dodecylbenzene sulfonate preferably for use, its weight percent content is respectively 0.01～1%.
Advantage of the present invention is under the acting in conjunction by nitric acid, hydrochloric acid, hydrofluoric acid, in the time of can being implemented in normal temperature and pressure conditions, processing to mixed type dirts such as carbonate, silicate, vitriol, phosphoric acid salt, sulfide, oxyhydroxide, glutinous mud, cleaning performance is good, applied widely, can improve the work-ing life of filter plate, enlarge the use range of ceramic filter.
