Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
First aspect present invention provides a kind of catalyst carrier combined filter element, as depicted in figs. 1 and 2, comprising: several
Fibrous layer 1, the fibrous layer are rolled up to be formed by fiber paper axis；And the catalyst being located between any two layers fibrous layer 1 carries
Body layer 2；Wherein, the catalyst support layer 2 includes: granular main carriers 21, is laid on the surface of the fibrous layer 1,
And assistant carrier 22, the fiber surface being coated on inside the fibrous paper, while being placed in and being laid with 21 shape of main carriers
At gap in, the assistant carrier 22 have cementing property.
Catalyst carrier combined filter element provided by the invention, first fibrous layer porosity with higher, can make
Obtaining assistant carrier is in " wetting " state on fibrous layer, and assistant carrier can flow into the hole in fibrous layer, is attached to fiber
Crosspoint between fiber and fiber and fiber surface, and then the secured intensity of reinforcement fibrous layers in layer are formed more steady
Fixed structure, and then form self supporting structure；Assistant carrier can consolidate granular main carriers again, so that mainly
Carrier is stablized between fibrous layer, not easy to migrate in subsequent heating and reaction process and destruction；Finally, assistant carrier itself
Also the load factor of active component can be substantially increased, the catalytic performance of catalyst is improved in subsequent complicated active component, and
And catalyst carrier preparation process of the invention is simple, while it is multiple catalyst carrier can be adjusted according to the amount for adjusting assistant carrier
The pore-size distribution and intensity of filter element are closed, adjustment process is simple.
Catalyst carrier combined filter element in the application, main carriers and assistant carrier therein can according to need
Setting, such as denitration and the de- field VOCs, main carriers and assistant carrier can take off the common carrier of VOCs for denitration, as long as main
Wanting carrier is graininess (powder, solid), and assistant carrier has cementing property (generally fluid, lotion).
As an example, main carriers can be carbon nanotube, TiO2Powder, molecular sieve etc., or above-mentioned one kind
Or a variety of mixing.Assistant carrier can be one of silica solution and Aluminum sol or a variety of mixing.
In the application, the porosity of the fibrous paper after by " wetting " and solidifying is more appropriate, and one side pressure drop is small, another
Aspect can prevent dust particles through fibrous paper, have the function of filtering.
Silica solution and Aluminum sol are emulsion form, have fluid properties, therefore can fall into main carriers by flowing
In gap and the gap of fibrous layer.It is since assistant carrier has cementing property, main carriers and fibrous layer are firmly solid
It is fixed.
