Description
Technical field
The present invention relates to exhaust-gas treatment field, the catalyst carrier that more particularly to a kind of use double-layer plate makes.
Background technology
Metallic catalyst carrier is mainly used in placing metallic catalyst, there is through hole, metal catalytic in metallic catalyst carrier
Agent is placed in metallic catalyst carrier through hole, is then allowed waste gas to pass through carrier through hole and is occurred instead with the metallic catalyst on carrier
Should come to process waste gas, the matrix inside current catalyst carrier is generally single layer structure and its stability is relatively low, one
Denier inner base is clashed into, and is easily caused inner base and is deformed upon, and the catalyst on compartment or air flue is impacted,
Reduce its catalytic efficiency.
The content of the invention
For the catalyst carrier that problem above, the present invention make for a kind of use double-layer plate, the catalyst carrier bag
Include housing and carrier matrix；Carrier matrix includes outer sheet metal and internal layer thin plate, and outer sheet metal is neodymium iron boron plate, internal layer thin plate
It is to use pyrolytic oxide preparation, the moulding bodies thin plate with catalysis activity；Adjacent inner layer thin plate constitutes a compartment, each
Compartment outer wrap has outer sheet metal.Outer sheet metal uses neodymium iron boron as material, with outstanding intensity and magnetic so that
Can mutually be adsorbed between outer sheet metal, can mutually be absorbed when being impacted, reduce impulsive force.Internal layer thin plate is with pyrolitic oxidation
Thing is material, and when the tail gas of high temperature passes through, the treated thin plate with catalysis activity accordingly decomposites catalyst and comes right
Tail gas carries out catalytic reaction.
As a further improvement on the present invention, compartment is regular polygon.Be can guarantee that between outer sheet metal from regular polygon
Can be in close contact.
As a further improvement on the present invention, outer sheet metal is 2mm with internal layer lamella thickness.
As a further improvement on the present invention, the specific preparation method of internal layer thin plate is：
A, making sheet：Pyrolytic oxide is fabricated to thin plate according to size requirements, pyrolytic oxide be silica, aluminum oxide,
One or more in titanium oxide and zirconium oxide；
B, pre-activate：The thin plate made is processed by acidic cleaning liquid, and is dried；
C, surface treatment：Alkyl silicate is evenly coated in thin sheet surface；
D, drying：Thin plate is put into temperature for 60-70 DEG C, environmental stress are 1.4x105~1.5x105Carried out in the environment of Pa
Dry；
E, water process：Thin plate is immersed in the water or the slurrying in water；
F, calcining：Calcining heat is 850-950 DEG C, a length of 4-5 hours during calcining.
The catalyst carrier that the present invention makes for a kind of use double-layer plate, carrier matrix is by using internal layer and outer layer
Thin plate constitutes regular polygon to constitute, and outer sheet metal is used using the neodymium iron boron with excellent in strength and magnetic, internal layer thin plate
Prepared by pyrolytic oxide, the moulding bodies thin plate with catalysis activity, therefore the impact resistance ability of catalyst carrier is not only lifted,
Improve intensity, and catalytic efficiency when can guarantee that tail gas by its compartment air flue.
