Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
The high temperature reduction atmosphere catalyzer sampling jar that the utility model provides comprises sampling jar inner core 7, sampling jar urceolus 8, and be arranged at injection port 1, outlet 10, the exhausr port 2 of sampling jar inner core 7; Wherein, described outlet 10 and exhausr port 2 are located at respectively the two ends of inner core 7, and described injection port 1, outlet 10, exhausr port 2 are respectively equipped with valve.
The sampling jar that the utility model provides, described exhausr port 2 place's ends are provided with strainer tube 5, and described strainer tube 5 can be assemblied in the inside of sampling jar inner core.Namely the end at described exhausr port 2 is provided with strainer tube 5, exhausr port valve 3 successively.
The sampling jar that the utility model provides is provided with two injection port arms outside the described injection port valve 11, arm is provided with arm valve 12,13, and described injection port valve and two arm valves 12,13 form the injection port valve sets.Wherein, described injection port valve sets is comprised of three valves, and three valves lay respectively on three strands of paths of injection port and two arms, control sampling jar and reactor mode of communicating in sampling process.
The sampling jar that the utility model provides, described exhaust ports arranges tensimeter 4.In the preferred case, described exhausr port end is provided with strainer tube 5, tensimeter 4, exhausr port valve 3 successively.
The sampling jar that the utility model provides preferably, arranges handle 6 on the described sampling jar urceolus.Described handle can be at least one, handle be shaped as circular-arc or other shapes easily, the utility model is not limited in this respect.
The using method of the reactor particulate solid sampling jar that the utility model provides is as follows, at first open injection port valve, outlet valve and exhausr port valve before the sampling, then pass into inert gas from outlet and get rid of air in the sampling jar, make inert gas be full of pipeline between whole sampling jar inner core and inner core and each valve, close successively subsequently injection port valve, outlet valve and exhausr port valve.Described inert gas preferred nitrogen.
Take sampling jar that the injection port valve sets is set as example, an arm of sampling jar injection port is connected with the outlet of unloading of the particle to be got of reactor to be taken a sample, the described sampler for the treatment of is fluidizing reactor or the moving-burden bed reactor that is in reducing atmosphere.Close the injection port valve, open injection port arm valve 12,13, begin to unload a small amount of particle to get rid of the sampling jar injection port and to treat that sampler unloads the air between the connecting line of outlet.
