Gas circuit is integrally used to hydrogen sulfide chemical inert material, but be not limited to silica gel, polytetrafluoroethylene (PTFE) etc..Gas-liquid separation lid is used to sulphur
Change Hydrochemistry inert material, processed using numerically-controlled machine tool, there is gas liquid separating function, material is not limited to polytetrafluoroethylene (PTFE), highly dense
Spend polypropylene etc..Peristaltic pump is driven using brush motor, the acid resistances bullet such as silica gel, EPDM ethylene propylene diene rubber, VITON fluorubber
Property material.Pressure bottle is using materials such as high borosilicate, high density poly propylene, polytetrafluoroethylene (PTFE).Electric control part is prolonged using metal-oxide-semiconductor circulation
The control loops time such as Shi Kaiguan.
Acid or other releasing agents is added to pressure-resistant sample bottle in peristaltic pump, and hydrogen sulfide is released at molecular state in sample bottle
Come, aeration is then bubbled by circulating pump and is purged out, until pressure-resistant absorption bottle, is absorbed agent absorption, unabsorbed hydrogen sulfide
It continues cycling through, until absorbing complete.Releasing agent is added in peristaltic pump and circulation time passes through two metal-oxide-semiconductor circulation delay switch respectively
Control.
