MANUAL SAMPLING SYSTEM FOR REACTOR:
This system is an anti-corrosion manual sampling device.The parts in contact with the samplingmedium are lined with PFA or Fluorine to achieve anti-corrosion purpose.The Teflon suction pipematched with the insertion pipe (fluorine lined /glass lined)is immersed below the medium liquidin the vessel to increase the stability of the process.The medium is sampled safely and quickly inthe system by vacuuming.
Sampler Installation and Sampling Steps:
Installation procedure
1.Install (the insertion pipe)on the corresponding nozzle of the reactor and fasten the bolts.
2.Separate the lower end (base)of the sampling system from (diaphragm valve 1),and install (base)to the upper end of(insertion pipe).
3.Put the Teflon outer flanging (suction pipe)into the inner cavity of the (base),and the Teflon outer flange of(the suctionpipe)is matched at the sealing surface of the (valve seat).
4.Connect and tighten the rest of the sampling system body to ensure that the sealing part of (base)is tight and withoutleakage.
Note:The base part can be canceled when connecting the device with small diameter pipe.
Sampling procedure
1.Confirm and check before starting:
a.All diaphragm valves are closed.
b.There is no residue inside and outside the sampling system,and no damage to the sightglass.
c.The vacuum system is connected to the corresponding vacuum interface and ensure that the seal is leak-free.
d.0.2~0.3 MPa nitrogen gas source is used for back blowing.
e.One spare 150/250 ml boroslicate glass sampling bottle is needed.
2.Suction:
a.Open(diaphragm valve 1).
b.Open(diaphragm valve 2)in time.
c.Observe (sightglass).The floater slowly rises and mediumfills the sightglass window.
d.Close(diaphragm valve 1 and diaphragm valve 2).
3.Sampling
a.Open (diaphragm valve 3).
b.Open (diaphragm valve 4).Observe the dosage of the sam-pling bottle
c.Close (diaphragm valve 3 and diaphragm valve 4).
d.Remove the (sampling bottle)and seal the bottle mouth -putin (spare sampling bottle).
e.Open(diaphragm valve 1)—Open(diaphragm valve 5)—Open (diaphragm valve 3 and diaphragm valve 4).
Make nitrogen blow the residual medium in the system backinto the vessel.
f.Close (diaphragm valve 1,diaphragm valve 3,diaphragmvalve 4 and diaphragm valve 5).
g.Sampling complete.
Descipton ofthe Cleantng Proces ofthe Reactor with Nenual Samplng System:
During the cleaning process of the whole reactor,the internal cleaning and purging of the sampling systemcan be carried out according to the above sampling steps.
