Description
Technical field
The utility model belongs to a kind of sampler being applied to the online particle sampling of miniature fluidized bed.
Background technology
The research such as traditional catalyst reduction, evaluation, inactivation, regeneration is carried out usually in fixed bed, but due to the unevenness of catalyst granules distribution in fixed bed, the reactiveness of the catalyst granules of different loading position is not quite similar, and the getable catalyzer of institute is not necessarily representative; In addition, traditional research method could take out catalyzer after question response can only be waited to terminate, and what obtain can only be catalyst granules that is fresh and reaction, for the change information of catalyzer with reaction, lacks suitable research means.
Miniature fluidized bed has good mixed performance, and catalyst granules is uniformly distributed in fluidized bed, is in identical reactiveness, can ensure that the catalyst granules in bed is representative, this utility model is by the reduction of miniature fluidized bed applications to catalyzer, evaluate, inactivation, the processes such as regeneration, the sampler unique in conjunction with design carries out continuous on-line period to catalyzer, namely while not affecting chemical reaction, catalyst granules is taken out, obtain the catalyst granules in course of reaction, and be not only fresh in catalyst granules that is inactivation, realize reduction, evaluate, inactivation, the Collection and analysis of catalyzer information in the processes such as regeneration, and then tracking sign is carried out to whole course of reaction, contribute to the change behavior of the Study of Catalyst each reaction process in surface and catalyzer itself.
The method of online for miniature fluidized bed particle sampling can be introduced the research process of heterogeneous catalyst; its advantage is in the process such as reduction, evaluation, inactivation, regeneration of catalyzer; do not stop reacting and the catalyst granules that obtains in course of reaction; inertia protection is carried out to the catalyst granules taken out simultaneously, farthest maintain the reactiveness of catalyst granules.By to take out catalyst granules carry out characterization research and in association reaction process Different periods tail gas composition monitoring analysis, can realize the seizure of species in the middle of in catalytic reaction process really and obtain change procedure, the tendency information of catalyzer with the reaction time, change existing catalyst research method have to react before and after the drawback of catalyzer.
In order to adopting said method, can design can on-line period realize the device of inert atmosphere protection, and one of fundamental purpose of this device is exactly form inert gas environment, and makes catalyst granules farthest not residue in whole sampling and protective device.And in existing sampling technique, the taking-up of catalyst granules is all comparatively complicated with protection.Such as, Chinese patent (CN 202255960 U) devises a kind of fluidized particles sampling apparatus and sampling system, be mainly used in recirculating fluidized bed sampling, this patent pumped vacuum systems and purging system share connector, namely purge and are difficult to carry out with vacuumizing simultaneously; Chinese patent (CN 203365172 U) devises a kind of high temperature, high pressure, flammable solid liable to sponta neous combustion fluidized bed sampler, the phenomenon of material burning when solution high temperature, high pressure, the sampling of flammable solid liable to sponta neous combustion fluidized bed, need the pressure discharge operations of sampler before the sampling of this patent to purge to protect the particle taken out, can reach and sample smoothly; Chinese patent (CN 2655219 Y) devises a kind of suction type granular substance sampler, negative pressure is utilized to sample device interior, this patent uses same inertia source of the gas to purge sampling hut and sampling line, can only be taken up in order of priority and purge sampling hut and sampling line; Chinese patent (CN 202974705 U) devises a kind of reactor particulate solid sampling jar, for the solid particle sampling in reducing atmosphere under high temperature, this patent gets rid of air between fluidized bed sample tap and sampling jar by releasing a small amount of particle before sampling, catalyst granules in fluid bedreactors causes waste, and this is very important in the laboratory study using small amount catalyzer.
In laboratory study process, the difference maximum with commercial Application process is that the amount of at every turn testing the catalyzer used is considerably less, sampling neither should affect catalytic reaction can meet follow-up study needs again, therefore how quantitative taking-up catalyzer, making the catalyst quality of taking-up moderate is problem demanding prompt solution, also carries out the report of follow-up study not about the catalyzer that can quantitatively take out at present about in the document of fluidized bed sampling.
Got particle is put into again the design of containing sample bottle after the sampling of listed patent Jun Shi sampling hut above, these design ap-plication are at relatively large device, the handling of equipment can be reduced, but in laboratory operation process, the evaluating apparatus of catalyzer is general less, corresponding required sampling hut's volume is also less, after designing more complicated sampling hut's miniaturization, use inconvenience, and particle is transferred to contain sample bottle process from sampling hut and very easily contact with air, sampling hut's Long-Time Service certainly exists remaining of catalyst granules powder.
To sum up, design and purge completely and the sampler of not easily residual particles, and be applied to the sampling of miniature fluidized bed online particle and be very important, these parts also should guarantee that whole process sampling bottle inside does not contact with ambient atmosphere simultaneously, the connection of pipeline is easy as much as possible, so that operation.
