Abstract
The invention is a fabrication process for a meerschaum air purifying agent. According to the invention, purified meerschaum with a purity no less than 80% produced by Hunan Hongyan Meerschaum Technology Ltd. is used as a raw material; a finished product is prepared by carrying out a reaction in a hydrochloric acid solution at specific temperature under the conditions of pressurization and stirring, carrying out automatic extraction and reverse osmosis with a membrane machine and repeated rinsing and filtration until the pH value of a resultant is about 6, dehydrating the resultant with a plunger pump and a filter press so as to obtain a filter cake, drying the filter cake with a flash evaporation drier to obtain powder, allowing the filter cake to enter into a chain pulverizer and an extruder for processing so as to obtain master batch, adding powder into the master batch, putting an obtained mixture in a rotary pelleting machine for water spraying and granulation and drying obtained granules in an adjustable rotary drier to obtain the meerschaum air purifying agent. The fabrication process guarantees hole capacity of meerschaum; the prepared meerschaum air purifying agent which is an adsorptive purifying material used for treating environmental pollution has greater capability of adsorping formaldehyde than other charcoal products do under a same condition, having a removal rate no less than 86%.
Description
Technical field
The present invention relates to a kind of fabrication process for meerschaum air purifying agent.
Background technology
Indoor environment at present, the air pollution of PE is more serious, one of the primary pollution source that particularly indoor decorating brings " formaldehyde " is confirmed as a class carcinogenic substance by the World Health Organization, and in the market for indoor environment, the PE air pollution purified product that especially formaldehyde pollution aspect is administered is very different, parameter is different, carry out the Product Activity charcoal of physical absorption, bamboo charcoal, the adsorption capacity of these class polar molecules of PARA FORMALDEHYDE PRILLS(91,95) such as charcoal carving is quite limited, they just the air pollutants of the macromolecular particle to nonpolar molecule possess certain absorption advantage, because of its release of formaldehyde for up to 3-15.And chemical decomposition method is other method in the market, but cure the symptoms, not the disease.
Sepiolite is rare nonmetallic mineral, its significant characteristic is adsorptivity, suspension, catalytic, ion exchangeable etc., the aperture of its distinctive 0.36-1.06 nanometer is just being suitable for receiving harmful polar gas molecule and is living, therefore the feature of the strong adsorption indoor harmful gas polar molecule thing (formaldehyde, ammonia, radon gas, hydrogen sulfide, nitrogen etc.) of this product uniqueness has obtained the relevant experts' such as Chinese Indoor Environment Detection center, CDC abundant affirmation, has filled up the market vacancy of sepiolite as air clearing product.But because domestic natural sea afrodite purity is low, interstitial channels is full of and tamps by many impurity, extremely affect its specific area (900m
2/ g), so domestic natural sea afrodite cannot reach the adsorptivity of expection, more do not reach the index of air clearing product requirement.
Summary of the invention
Department, to the purify manufacture craft of further activation modification on the basis of (purify after sepiolite purity >=80%) technology of natural sea afrodite, makes the adsorptivity scavenging material sepiolite air purifying preparation for indoor environment pollution.
Solution of the present invention is: selecting to adopt the purification sepiolite of sepiolite purity >=80% of Hunan swan goose sepiolite Science and Technology Ltd. is raw material, by following technology mode step:
(1), adopt specification 5-10m
3reactor equipment is made container, raw material is immersed in the hydrochloric acid solution that concentration is 0.5%-10.6%, at the normal pressure of≤0.6Mpa ,-5-180 DEG C temperature, with rotating speed 48-300f/p stirring reaction 4-24h;
(2), the stirring material after upper step is entered to 5-10m
3in the anticorrosion material storage container of volume, being filtered to pH value by the counter-infiltration of film machine Automatic Extraction, cyclic washing is 6, is placed in material storage container;
(3), will be dehydrated into filter cake by plunger displacement pump, filter press through the material of upper step process, the moisture content of filter cake is 40-50%;
(4), upper step is made to 33% of filter cake and under temperature 150-300 DEG C condition, be dried to powder by flash dryer; All the other 67% filter cakes enter chain crusher and are ground into fritter, then with extruder, fritter are processed into the master batch of 0.5-3mm;
(5) master batch of, upper step being made adds the powder granulation of spraying water in rotary pelleting machine; again the grain of making is dried to finished product at temperature 100-500 DEG C in adjustable rotary drying oven; its moisture content of finished products is controlled at < 0.3%, by product cut size screening finished product sepiolite air purifying preparation.
The invention has the beneficial effects as follows: according to the natural network pore passage structure of sepiolite, the permanent negative electrical charge in surface and ion-exchange performance thereof, carry out acidifying, heating, pressurization, the materialization processing of stirring, the further activation modification of purification sepiolite of the sepiolite purification technique to employing Hunan swan goose sepiolite Science and Technology Ltd., making its duct impurity obtain fully acidifying dissolves, ensure the pore capacities of sepiolite, impel sepiolite surface to be permanent negative electrical charge, make the adsorptivity scavenging material sepiolite air purifying preparation that is used in indoor environment pollution, after testing, under equal conditions, the ability of this sepiolite air purifying preparation absorption formaldehyde substantially exceeds charcoal series products, clearance >=86%.
detailed description of the invention
Selecting to adopt the purification sepiolite 800kg of sepiolite purity >=80% of Hunan swan goose sepiolite Science and Technology Ltd. is raw material, by following technology mode step:
