The beneficial effects of the precious metal catalytic net activation device are that, the precious metal catalytic net activation device can completely remove impurities attached on the net in the manufacturing process of a catalytic net, and ensures catalytic efficiency and activity of the catalytic net.
Description
Technical field
The present invention relates to chemical industry noble metal and manufacture field, especially a kind of activation method of precious metal catalyst net and device.
Background technology
Industry preparing nitric acid by ammonia oxidation industry needs to use precious metal catalyst net to improve reaction efficiency, and needs through overactivation before new catalysis net makes installation, its objective is the firing temperature reducing catalysis net.
The mainly hydrogen flame burning of existing activation method, by being attached to the combustible of net surface in hydrogen flame burning removing catalysis net manufacture process.But online attachment can not remove by single hydrogen flame burning completely.
Summary of the invention
In order to the impurity be attached on catalysis net being removed completely, the invention provides a kind of activation method and device of precious metal catalyst net.
The present invention is achieved through the following technical solutions:
An activation method for precious metal catalyst net, comprises the following steps:
1) remove with hydrogen flame catalysis net retains organic matter;
2) catalysis net is inserted remove electro-coppering except in plating solution;
3) soluble pollutants on catalysis net surface is removed in washing;
4) catalysis net after washing is hung up and is dried.
Further, described step 1) to retain organic matter be polyvinyl alcohol.
Further, described step 2) in except plating solution to be concentration be 5 ~ 10% sulfuric acid or hydrochloric acid.
Further, described step 3) to wash water used be deionized water.
A kind of activating apparatus of precious metal catalyst net, comprise flame combustion apparatus, except plating appts and elution device, it is characterized in that described flame combustion apparatus comprises hydrogen flame rod, flame stand and catalysis net spool, except plating appts comprises except coating bath, flush box and smoke extractor, elution device comprises hanger and washing nozzle.
Further, described flame stand is the support of horizontally set, and hydrogen flame rod is arranged on flame stand, and catalysis net spool is arranged at above support.
Further, described smoke extractor is arranged at except directly over coating bath.
Beneficial effect of the present invention is: can remove completely in catalysis net manufacturing process and be attached to online impurity, ensures catalytic efficiency and the activity of catalysis net.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
In order to make technological means of the present invention, creation characteristic, reach object and effect is easy to understand, below in conjunction with accompanying drawing specific embodiment, the present invention is further elaborated.
Activating apparatus of the present invention comprises flame combustion apparatus, except plating appts and elution device, described flame combustion apparatus comprises hydrogen flame rod 12, flame stand 13 and catalysis net spool 14, flame stand 13 is the support of horizontally set, hydrogen flame rod 12 is arranged on flame stand 13, and catalysis net spool 14 is arranged at above support 13.Except plating appts comprises except coating bath 22, flush box 23 and smoke extractor 24, smoke extractor is arranged at except directly over coating bath, and elution device comprises hanger 32 and washing nozzle 33.
During use, first remove with hydrogen flame and catalysis net retains organic matter polyvinyl alcohol, flame rod transverse reciprocating on flame stand moves, and net volume rises with certain speed by the catalysis net spool of top simultaneously; Then, after catalysis net cooling, catalysis net is inserted and removes electro-coppering except in plating solution, except plating solution to be concentration be 5 ~ 10% sulfuric acid or hydrochloric acid; Catalysis net hanger after washing is hung up, and preferred catalysis net hanger is two hanger groups having difference in height, and shower nozzle is vertical with the catalysis net of hang-up to be arranged, and spends by shower nozzle the soluble pollutants that deionized water removes catalysis net surface; Wash the hang-up of the catalysis net after 3 ~ 5 times to dry.
More than show and describe its general principles and principal character and advantage.The technical staff of the industry should understand; the foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent transformation utilizing description of the present invention and accompanying drawing content to do; directly or indirectly be used in the technical field that other are relevant, be all in like manner included in scope of patent protection of the present invention.
