Abstract
The invention relates to a preparation method of a composite photocatalytic oxidation nano titanium dioxide preparation. When being used in a water treatment technique by a photocatalytic oxidation process, the preparation can be uninterruptedly used for a long time without complex recovery equipment. The preparation method comprises the following steps: 1) mixing: sufficiently mixing 75-85% of modified zeolite powder, 10-20% of tourmaline powder and 4-6% of nano titanium dioxide powder to obtain mixed powder; 2) granulation: filling the mixed powder into a granulator, and carrying out centrifugal rolling on the composite powder by spraying water glass adhesive to obtain 1-3mm granules; and 3) sintering: after naturally drying the granules of the composite powder, baking at the low temperature of 100-120 DEG C in a kiln for 30-60 minutes, and sintering at the high temperature of 800-900 DEG C for 120-180 minutes.
Description
Technical field
The present invention relates to the preparation method of photochemical catalytic oxidation nano titanium oxide preparation, especially a kind of preparation method of compound photochemical catalytic oxidation nano titanium oxide preparation.
Background technology
Photochemical catalytic oxidation is a kind of Photosensitized Oxidation take the N-shaped semiconductor as sensitizer, its outstanding feature is that oxidability is extremely strong, in the N-shaped semiconductor of numerous optical sensibilizations, the photochemical stability of titanium dioxide and catalytic activity are all fine, and the character before and after the reaction is constant, therefore is used in the water treatment technology of photocatalytic oxidation.But photocatalytic oxidation need to reclaim and reuse, and is complicated because of equipment, causes the water treatment expense high, limited the application in the advanced treatment process of water.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of preparation method of compound photochemical catalytic oxidation nano titanium oxide preparation, and said preparation does not need complicated reclaimer when being applied in the water treatment technology of photocatalytic oxidation, can continual long-term use.
The preparation method of a kind of compound photochemical catalytic oxidation nano titanium oxide preparation of the present invention may further comprise the steps:
1. blend step: with the modified zeolite powder of 75%-85%, the tourmaline powder of 10%-20%, the nanometer titanium dioxide titanium valve of 4%-6% fully mixes, and obtains mixed powder;
2. balling-up step: mixed powder is contained in the nodulizer, sprays the centrifugal spherical particles that rolls into 1mm-3mm of composite powder with water glass binder;
3. sintering step: after the spherical particles of composite powder is natural drying, is placed in the stove of cellar for storing things and cured 30 minutes to 60 minutes with 100 ℃ of-120 ℃ of low temperature, then use 800 ℃-900 ℃ high temperature sintering 120 minutes to 180 minutes.
The specific embodiment
Following embodiment is for the more detailed the present invention of explanation, is confined to this but should not be construed as the present invention.
Embodiment 1:
The preparation method of a kind of compound photochemical catalytic oxidation nano titanium oxide preparation of the present invention may further comprise the steps:
1. blend step: the modified zeolite powder with 75%, 20% tourmaline powder, 5% nanometer titanium dioxide titanium valve fully mixes, and obtains mixed powder;
2. balling-up step: mixed powder is contained in the nodulizer, sprays the centrifugal spherical particles that rolls into 2mm of composite powder with water glass binder;
3. sintering step: after the spherical particles of composite powder is natural drying, is placed in the stove of cellar for storing things and cured 45 minutes with 110 ℃ of low temperature, then use 850 ℃ high temperature sintering 150 minutes.
The invention has the beneficial effects as follows:
1. be the composite granule of nano titanium oxide owing to having adopted modified zeolite, tourmaline, modified zeolite and tourmaline have oxic processes and cheap in water.
2. because the modified zeolite porosity is very high, unit weight is little, so the composite powder spherical particles becomes suspended state under the effect of current, can fully accept various light sources, and catalytic oxidation efficient is high.
Since the composite granule diameter than large many of nano-titanium dioxide powder, microballon, so do not need complicated reclaimer, operating cost decrease.
More than design is only for explanation the present invention's, and be not to be limitation of the present invention, the those of ordinary skill in relevant technologies field, in the situation that does not break away from the spirit and scope of the present invention, other variation of having done and the technical scheme that all are equal to also should belong to category of the present invention.
