Description
Technical field
The present invention relates to a kind of new material and new technology for being catalyzed organic gas, specially a kind of new catalytic organic gas
Catalysis cotton material preparation.
Background technique
It is existing current domestic and in the world for organic gas such as natural gas, liquefied gas, its burning is mainly made with igniting
Heat is generated, while a part of heat is radiate in the form of infrared ray.Heat is generated for these organic gas ignition
The method of amount is lighting a fire unsuccessful and gas leakage in confined space, is meeting open fire and easily generate explosion danger.And use this hair
Bright catalysis cotton carries out catalysis burning to organic gas such as natural gas, liquefied gas, does not need open fire and lights, and is an oxidation reaction mistake
Journey, so not having explosion hazard.
Meanwhile the method that traditional combustor or other open fires lights the organic gas such as natural gas, liquefied gas, it is general to only have
95% or so organic gas is sufficiently burned, and the insufficient carbon monoxide that is converted into of rest part burning is wasted, closed
Easily personnel is caused to suffocate in space.And catalysis combustion system is used, and it is not only safe, and organic gas can be close to 100%
It is oxidized and reacts away, be not likely to produce carbon monoxide.
The relatively traditional open fire combustion system of catalysis burning, the energy overwhelming majority are radiate in the form of infrared ray,
It is unobvious to air heating, it has great application prospect in industries such as coating heating, heating of house, exhaust-gas treatments.
Summary of the invention
Present invention solves the technical problem that the defects such as being to overcome the waste of energy of the prior art, production security low, mention
For a kind of catalysis cotton material preparation of new catalytic organic gas.A kind of catalysis cotton material system of the new catalytic organic gas

Compared with prior art, the beneficial effects of the present invention are:
1, the reduction about 2/3rds more infrared than electricity of infrared operating cost is generated using fuel gas such as natural gases, because being pair
Fuel gas progress oxidation reaction generation is infrared, without igniting, so can also be used in combustible and explosive area.Because at work
Fuel gas positive pressure is by panel surface, so more dirt, drying powdery paints, conductive material are not easy to drift work at work
On panel, corresponding occasion be can also be used；
2, with electric heating tube heatable catalytic cotton, make to be catalyzed the oxidation reaction that carries out that cotton surface temperature reaches fuel gas
Temperature, this process only has about 10-15 minutes or so, so electricity consumption is smaller；
3, it adjusts fuel gas air inflow or adjusts the content of catalyst platinum, it is infrared to can produce shortwave, medium wave, long wave etc.
Line, to meet different drying requirements；
4, aluminium dioxide fibre diameter is 2-4um, more abundant in the catalysis reaction of this diameter range；
5, the mass percent of platinum is 1.0%-5% in platinum catalyst.
