Background technology
Prepare dehydrogenation often the mixture of copper and aluminum is added in crucible and fusing is heated in prior art, so
Poured in the resistant to elevated temperatures diaphragm capsule for making in advance, after alloy solution natural cooling afterwards, make albronze block, then use again
Jaw crusher, gyratory crusher are crushed, and after the granule after crushing is with vibrosieve screening, dealuminzation makes dehydrogenation.
The dehydrogenation prepared using this kind of method, in albronze solution, due to the proportion of copper it is bigger than aluminum, from
So stand in cooling procedure, copper can sink to solution bottom and cause albronze uneven components, so as to the micropore of the copper after dealuminzation
Few, catalyst activity is low, and usage cycles are short, increases production cost；Made by alloyed powder specific surface area it is less；Naturally it is cold
But the time is long, and the catalyst preparation cycle is long, commercial production high cost；The preparation of the method is first to prepare albronze ingot, then
Mechanical activation comminution is carried out, its process energy consumption is increased, mechanical noise is big, while producing a large amount of metallic dusts, can also bring a part into
Ferrum element in machinery so as to affect catalyst catalytic performance, reduces the performance of subsequent product in catalyst.
Therefore at present the preparation method of dehydrogenation exist that catalyst activity is low, alloyed powder specific surface area is little,
The problems such as rate of temperature fall is slow, mechanical activation comminution energy consumption is big, dust is more, noise is big.
The content of the invention
For the problems referred to above, the present invention proposes a kind of preparation method of dehydrogenation, improves catalyst activity, drop
Warm speed, reduces mechanical activation comminution energy consumption.
The present invention solution be：
A kind of device for preparing dehydrogenation, including eruption device, drain pipe, gas box, eruption device bottom open up circular hole, gas
Closing inside box, sleeve pipe being set in the middle part of gas box, drain pipe one end connection circular hole one end passes through sleeve pipe, air inlet arranged at the top of gas box
Mouthful, gas outlet being opened up away from eruption device one side periphery in sleeve pipe, gas outlet is arranged on gas box box body, and gas outlet and drain pipe are remote
From eruption device side simultaneously towards spray room.
Further, facilitate pouring into for alloy liquid to divide, eruption device is open-topped arc-shaped eruption device.
Further, in order to let the liquid out, the aperture of eruption device bottom circular aperture is 2～4cm.
Further, air draught, air inlet connection air compressor are passed through in order to continual.
Further, in order that gas forms high-speed air air-flow, the hole of gas outlet between sleeve pipe and the gas box in gas outlet
Footpath is 2～6mm.
A kind of method for preparing dehydrogenation, alloy liquid is poured in eruption device, and alloy liquid is from eruption device bottom
Jing drain pipes flow out；Gas box air inlet connects air compressor, and gas outlet forms high-speed air air-flow；The conjunction flowed out in drain pipe
Golden liquid forms copper-aluminum alloy powder with high-speed air air flow contacts, and copper-aluminum alloy powder is sprayed onto in spray room, and powder is taken off after collecting
Aluminum, makes dehydrogenation.
Further, alloy is albronze.
Further, copper and aluminium mixture are added in crucible, crucible is heated to 800～1050 DEG C to copper and aluminium mixture
Fusing, obtains albronze solution.
Further, in the mixed thing of copper and aluminum, the mass fraction of copper is 30%～60%.
Compared with prior art, it is an advantage of the current invention that：Albronze solution directly sprays, rapid to cool down, and copper aluminum is closed
Bronze end is evenly distributed, and after dealuminzation, the micropore of copper is more, and specific surface area of catalyst is big, and catalysis activity is high, without metallic dust without production
Noise, energy consumption are low, and catalyst usage cycles can extend one times.
