Description
Technical field
The utility model relates to a kind of dead palladium catalyst pre-treatment decarbonization device, especially can process the decarbonation appliance of petrochemical industry spent catalyst in a large number.
Background technology
In catalyzed reaction, carbon deposit or coking are almost inevitable.The precious metal reclaimed in catalyzer needs dissolve carrier or dissolve precious metal, often there is a large amount of carbon deposits, carbon deposit and organic existence, easily produce " cruelly excessive ", cause precious metal losses in dissolution process in used catalyst support duct.On the other hand, the carbon deposit in spent catalyst and organism wrap up and adsorb the dissolving that precious metal also affects precious metal.For improve organic efficiency, usually need in advance by spent catalyst through carbonization treatment, removing carbon distribution and organism etc.Therefore, decarburization is the important step reclaiming precious metal in Effect of Catalysis In Petrochemistry agent.
Usual spent catalyst, through roasting, removes carbon wherein and organism.Roasting is carried out in retort furnace, is loaded in vessel by spent catalyst and puts into retort furnace, is preheating to predetermined temperature, and being heated to required time can effective decarburization.From produce hydrogen peroxide dead palladium catalyst in Recover palladium experiment in find that bed thickness is the key factor affecting carbon-drop rate, 4mm bed thickness 600 DEG C of roastings decarburization in 0.5 hour is greater than 98%, 7mm bed thickness 600 DEG C of roastings need 1.5 hours carbon-drop rates are just greater than 98%, 10mm bed thickness, 600 DEG C of roastings, 5 hours carbon-drop rates and only have 70%.This is because static roasting spent catalyst, carbon wherein and organism contact by air molecule diffusion control with air, carbon bottom spent catalyst and organism are particularly housed the carbon on top and the complete air diffuser of organic compound combustion need be waited could to burn to bottom remove, this just extends static roasting decarburization time.For accelerating air diffuser speed, usually need to open some fire doors, although it is higher to accelerate air diffuser speed energy consumption like this.Few owing to testing the material used at every turn in laboratory study, be usually tens grams, bed thickness impact is little, but experimental study is produced after completing, and the decarbonization device of spent catalyst just becomes the large problem affecting output.
Utility model content
The deficiency of extensive process dead palladium catalyst pre-treatment decarburization can not be met in order to overcome existing static baking modes, the utility model provides a kind of dead palladium catalyst pre-treatment decarbonization device, this decarbonization device can not only remove carbon distribution in dead palladium catalyst and organism in large quantity, and efficiency is high and energy-conservation.
A kind of dead palladium catalyst pre-treatment decarbonization device of the present utility model contains: temperature housing (1), temperature thermocouple (2), body of heater (3), bell (4), dead palladium catalyst (5), gas communication device (6), spent catalyst container (7), rubber airway (8), gas meter (9), valve (10), air compressor (11), wherein temperature thermocouple (2) is popped one's head in and is placed in body of heater and is connected with temperature housing (1), gas communication device (6) to be placed in spent catalyst container (7) and to add dead palladium catalyst, spent catalyst container (7) is put into body of heater (3) inner roof brick and is placed in above body of heater, gas communication device (6) is connected with gas meter by rubber airway gas, air compressor (11) is connected with gas meter (9) by rubber airway (8) through valve valve.
Dead palladium catalyst pre-treatment decarburization adopts Dynamic Burning method, its know-why is that carbon containing and organic spent catalyst are heated to certain temperature, passes into air make carbon wherein and organic compound combustion be transformed into harmless carbonic acid gas and aqueous vapor body and remove from spent catalyst bottom even.For make carbon and organic compound combustion completely, carrier crystal formation remains unchanged and the burned air-flow of the excessive spent catalyst of tolerance takes away the tolerance causing damage and need control Heating temperature and pass into.Temperature control unit is formed, by set temperature housing state modulator temperature rise rate and temperature required value by temperature housing, temperature thermocouple, body of heater, bell.Form gas control unit by air compressor, valve, rubber airway, gas meter, produced stablize air pressure by air compressor, regulated valve obtains by observing gas meter the air capacity needing to pass into.Remove for making the carbon in spent catalyst and organism all burn efficiently, the air that need pass into can uniformly across the spent catalyst needing carbonization treatment, devise gas communication device for this reason, the gas passed into passes through gas duct, by gas communication dish, gas uniform is scatter, then uniformly across spent catalyst burning decarburization.During pre-treatment decarburization, spent catalyst container is put into body of heater, put into gas communication device, add and will process dead palladium catalyst, cover bell, connect gas communication device and rubber airway, opening temperature housing switch is warming up to temperature required, opens air compressor regulated valve to required flow, maintains certain aeration time thus reach decarburization object.
The beneficial effects of the utility model are:
1, adopt this device can not affect by bed thickness dead palladium catalyst pre-treatment decarburization, the pre-carbonization treatment of dead palladium catalyst can be carried out on a large scale like this, enhance productivity.
2, because the air passed into is by spent catalyst material, carbon wherein and organic compound combustion are more abundant, and carbon-drop rate is high.
3, the air passed into and the carbon in spent catalyst contact with organism fully, and burning decarburization time is short, and energy consumption is low.
