Detailed description of the invention
With reference to the accompanying drawings, in conjunction with concrete embodiment, the invention will be further described, to understand the present invention better.
Embodiment 1
For a mineral cleanser for purification of water quality, described mineral cleanser is obtained after pulverization process, high-temperature roasting process, aluminium process, acid treatment and hydrophobic treatment by natural zeolite.
Step 1, pulverization process: the ore containing amount of zeolite more than 75% of mining, after machined fragmentation, cross 10 mesh sieves, as the raw material manufacturing water quality cleansing agent.
Described natural zeolite is the Zeolite mineral that field is taked, and the content of General Requirements zeolite is more high better, preferred clinoptilolite and modenite.
Step 2, high-temperature roasting process: the ore in sand form of gained in step 1 is carried out high-temperature roasting, is first warming up to 450 DEG C, and at the temperature of 450 DEG C, roasting 50 minutes, then cooling is come out of the stove, and tapping temperature is 200 DEG C, and whole ore in sand form will be heated as far as possible equably.The high-temperature roasting furnace palpus employing aluminum material that described high-temperature roasting is used.
After constant temperature time, timely power-off, enters cooling period; Under the condition that fire door closes, lower the temperature 15 minutes, then by crack for a fire door very little crack, As time goes on, strengthen the gap of fire door gradually, with the speed making ore in sand form accelerate cooling.When temperature is down to 250 DEG C, ore in sand form has just been come out of the stove; After taking out ore in sand form, closed furnace door, makes the temperature of furnace remain as far as possible.
Step 3, aluminium process: the ore in sand form after high-temperature roasting process in described step 2 is put into the container that mass concentration is the aluminum salt solution of 4%, the weight of solution is 1/4 of ore in sand form weight; Under the condition of container covered and enclosed, ore in sand form is hot dipping 2h in a reservoir, and hot dipping temperature is 60 DEG C, then toasts 40 minutes at 250 DEG C.
Described aluminium salt comprises aluminum sulfate, aluminium chloride or aluminum nitrate, preferably sulfuric acid aluminium; The container of described heat soaking must adopt aluminum products or stainless steel products, must guard against use common iron.Flood in cooled ore in sand form and substantially there is not aluminum sulfate solution, but ore in sand form is moistening, so it is dry to carry out baking.
Step 4, the hot ore in sand form after aluminium process being dropped into mass concentration is soak 3 hours in the sulfuric acid solution of 8%, and clear water embathes, and residual pickling is fallen, and then toasts 1.5 hours at 120 DEG C.
Described sulfuric acid can be replaced with hydrochloric acid or nitric acid, but most preferably sulfuric acid; Acid soak container must be acid resisting material, as aluminium alloy, stainless steel, plastic plate etc.; Described sulfuric acid liquid level will cover described ore in sand form surface, and described sulfuric acid soak time is 1.5 hours; Then releasing sulfuric acid solution, flowing in sulfuric acid pool specialized, in order to again utilizing.
Step 5, hydrophobic treatment: spray water-repelling agent to by the ore in sand form after acid treatment, make to form one deck hydrophobic film on mineral crystal He on the wall of intracrystalline space, jail is attached and do not come off.
Described water-repelling agent is the mixture of cationoid hydroxyl silicon oil emulsion and containing hydrogen silicone oil emulsion, and the mass ratio of described cationoid hydroxyl silicon oil emulsion and containing hydrogen silicone oil emulsion is 7:3; The viscosity of described cationoid hydroxyl silicon oil emulsion and containing hydrogen silicone oil emulsion is 10 ~ 20PaS, concentration is 10 ~ 15%.
To described two kinds of mixing silicon breasts, dilute with water 25 times, is the water-repelling agent of practical application; Be sprayed on the ore in sand form of 150 DEG C of high temperature by the mixing silicon breast after dilution, moisture evaporates, and silicone oil adheres to the internal pore of ore in sand form and outer surface and forms one deck silicone oil film.During practical application, moisture is just difficult to enter in mineral, does not absorb water or absorbs water less, increases absorption exchange capacity to pollutant to reach ore in sand form.
Spray the amount of water-repelling agent, generally be no more than 10% of ore in sand form weight, the consumption of the preferred water-repelling agent of the present invention is no more than 8% of ore in sand form weight, and reaching every ore in sand form can be drawn onto water-repelling agent as far as possible, but adsorbance again can not be excessive, because the thin layer formed is too thick can affect effect.
Its colourity of drinking water, turbidity, total number of bacteria, amount of total colibacillus, content of beary metal etc. after the process of this mineral substance water quality cleanser can reach national drinking water standard GB5749-2006.
