Description
Technical field：A kind of production technology and complete set technology for natural zeolite being made with ripple cleavage method modified zeolite.
Technical background：Zeolite is the natural aluminosilicate acid salt ore that one kind can produce " boiling " phenomenon.Its crystal structure is silicon
The three-dimensional screen work that (aluminium) oxygen tetrahedron is linked to be, there is the hole and duct to differ in size in screen work, alkali metal, alkaline-earth metal ions and
Hydrone is all distributed in hole and duct.Zeolite is in waste water control, soil, water body Radioactive decontamination, environment-friendly building materials, feeding
Should all there is extensive use in feed additives, slow-release fertilizer, cosmetics manufacture, but current service condition is unsatisfactory.China
Zeolite reserves account for the 2/3 of the world, but dosage very little, and existing several mining plants are very depressed, and in half end-of-life state, reason is
The hole and duct of natural zeolite are mostly blocked by impurity, do not reach due effect in use, natural zeolite is changed
Property for the unimpeded modified zeolite in duct, its function is more preferably played, be problem in urgent need to solve.
Natural zeolite will solve four problems by modification in structure, be only possible to be used widely in practice：The
First, get through what natural zeolite was blocked by calcium and magnesium salt, zeolite water etc., it is impossible to the duct to play a role.Secondth, zeolite is played and adsorbed
Noisy anion is acted on, to be removed.3rd, many occasions have particular/special requirement to zeolite, by modification, autotelic and add
Enter some compositions and meet its requirement.4th, modified zeolite can will preferably attract nitrobacteria and denitrifying bacteria, rely on
Ammonia nitrogen of zeolite adsorption etc. is changed into nitrate nitrogen by nitrobacteria, and nitrate nitrogen is converted into nitrogen and water by denitrifying bacterium, so that
Modified zeolite constantly can be activated voluntarily, long-term role, make to fall too low using the cost of zeolite.Present many units are all
Modified zeolite is being done, but is lacking advanced appropriate technology, the modified zeolite made far cannot get above-mentioned requirements.We are by long-term
The technical method that high-quality modified zeolite is manufactured with ripple cracking process has been invented in research, preferably solves these problems.Have currently reached
Technological principle, plant equipment, technological process, the level that improved chemical fills in the gaps to complete a chain, modified zeolite have also produced supply in batches
Market.
The content of the invention：Existing cracking technique refers to a kind of substance change with heat for direct energy source into several sharp material mixings
The process of body, such as Petroleum refining, essence are thermal crackings.The present invention is that natural zeolite manufacture becomes second nature using high frequency waves as direct energy source
The more preferable modified zeolite of energy, and the complete set technology of its basic boom is not broken, as its name suggests, its essence is ripple cracking.Main hair
Bright point：
First, technical principle：Radio-frequency generator sends the signal for producing nonlinear wave, and transducer is converted electrical energy into by this signal
Into the mechanical energy of vibration wave, modifier aqueous solution is outwards propagated as the elastic fluid propagated.It is non-thread due to ripple when propagating
Property effect, cavitation effect and cavitation bubble are produced in medium, when cavitation bubble closes suddenly, will be produced one instantaneous strong
The shock wave spent more than suitable 1,000 atmospheric pressure.This shock wave is iteratively operating on the zeolite in reactive tank, gets lodged in zeolite pore
Impurity in road, which will be impacted, to be come, and is miscible in water, zeolite cavity get through after by the clear of running water and deionization liquid
Wash, the modified zeolite of function admirable is just made in drying.Because the impurity in zeolite cavity and contacting for duct screen work are weaker, as long as
Related parameter choosing is appropriate, and leaving away for impurity will not destroy the screen work of natural zeolite.
