Abstract
The invention relates to a dioxin catalyst for production of cellular bricks. The dioxin catalyst is prepared from, by weight, 90% of nanometer titania, 2.5% of nanometer vanadium pentoxide, 4% of nanometer tungsten trioxide, 1% of nanometer molybdenum trioxide and 2.5% of nanosilicon dioxide. The catalyst is prepared from the nanometer base materials, the catalyst more easily and fully adheres to the cellular bricks, the catalytic effect is more obvious, the processing difficulty and cost of the cellular brick type catalyst are reduced, the requirement for the catalysis achieving environment is lowered, and therefore energy efficiency is improved and energy is saved.
Description
Technical field
The invention belongs to honeycomb brick produce and dioxin catalyst technical field, relate in particular to one forThe dioxin catalyst that honeycomb brick is produced.
Background technology
At present, in honeycomb brick production process in order to reduce the discharge of dioxin, row all can be to honeycomb brick timeImmersion, catalysis; This process needs to use dioxin catalyst, the catalyst doing on the market, allBe that the composition with catalyst is made into honeycomb brick completely, and the environment temperature that generation catalysis needs existMore than 400 DEG C, ours is the surface that nanocatalyst is attached to honeycomb brick, has both used honeycombThe area of brick maximizes, and reduces the consumption of catalyst simultaneously. Both reduced adding of honeycomb brick formula catalystWork difficulty and cost, reduce for the environmental requirement that realizes catalysis, thereby it is energy-conservation to reduce efficiency.
Summary of the invention
For solving the above-mentioned problems in the prior art, the invention provides a kind of for honeycomb brickWhen production more easily, stick to more fully the surface of honeycomb brick completely, consumption is few, catalytic effectSignificantly dioxin catalyst.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A dioxin catalyst of producing for honeycomb brick, is prepared by following composition and percentage by weightForm: 90% nano titanium oxide, 2.5% nanometer vanadic anhydride, 4% nano tungsten trioxide,1% nanometer molybdenum trioxide and 2.5% nano silicon.
The invention has the beneficial effects as follows:
The present invention is by technique scheme, during for the production of honeycomb brick catalyst more easily, more abundantGround sticks to the surface of honeycomb brick completely, greatly reduces the consumption of catalyst, the catalytic effect of dioxinMore obvious, both reduced difficulty of processing and the cost of honeycomb brick, reduce for the environment of realizing catalysis and wantAsk, thereby it is energy-conservation to reduce efficiency.
The present invention, by adopting nanometer base material to make, can will just produce catalysis effect at 80 DEG C～90 DEG CReally, catalytic efficiency reaches 98%.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with enforcementExample, is further elaborated to the present invention. Should be appreciated that specific embodiment described hereinOnly, in order to explain the present invention, be not intended to limit the present invention.
A kind of dioxin catalyst of producing for honeycomb brick of the present invention, by following composition and heavyAmount percentage is prepared from: 90% nano titanium oxide (TiO2), 2.5% nanometer vanadic anhydride(V2O5), 4% nano tungsten trioxide (WO3), 1% nanometer molybdenum trioxide (MoO3) and 2.5%Nano silicon (SiO2)。
While utilizing dioxin Catalyst Production honeycomb brick of the present invention, first by dioxin catalyst withSolution mixes, is made into dioxin catalyst solution, then honeycomb brick is dipped in catalyst solution,Soak into, finally take out and dry.
Through experimental test, because dioxin catalyst of the present invention adopts said components and percentage by weight,Immersion process make catalyst more easily, stick to more fully the surface of honeycomb brick completely, andAt the temperature of 80 DEG C～90 DEG C, catalytic efficiency can reach 98%. Can greatly reduce like this consumption of catalyst,The catalytic effect of dioxin is more obvious, has both reduced difficulty of processing and the cost of honeycomb brick, reduce forRealize the environmental requirement of catalysis, thereby it is energy-conservation to reduce efficiency.
The above is the preferred embodiment of the present invention, it should be pointed out that general for the artLogical technical staff, under the premise without departing from the principles of the invention, can also make some improvement andRetouching, these improvements and modifications are also considered as protection scope of the present invention.
