Detailed description of the invention
Fig. 1 is the system schematic of the utility model.
Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
As shown in Figure 1, a kind of prime pretreatment system for the measurement of sulfide hydrogen sample provided by the utility model, packet
It includes a sample introduction and manually switches off ball valve BV02-001, the pneumatic shut-off valve XV-4751 of a sample introduction, a sample introduction pressure gauge PG-
4751, pressure gauge PG-4752 after a coarse filter F02-001, sample introduction gasification pressure reducing valve PCV-4751, a decompression,

Thermometer TG-4751, a hydrogen sulfide detector NGT-4751, a breather valve BR-001.
The course of work of above system are as follows:
The first step, open purging shut-off valve BV02-004, by the flow control of purging air 10L/H, that is, cabinet per hour
Displacement 6 times or more.Purge gass are discharged from breather valve BR-001.Hydrogen sulfide detector NGT-4751 powers on opening simultaneously.If inspection
Hydrogen sulfide is measured, then hydrogen sulfide detector NGT-4751 alarms at once, and sends alarm signal to DCS system.DCS system is at once
Shutoff signal is sent to solenoid valve XY-4751, solenoid valve XY-4751 cuts off pneumatic shut-off valve XV-4751 gas source, sample stop into
Sample.
Second step, it is known that sample strain, temperature and component information.Sample is transmitted to prime via field sample transfer line
Pretreatment system is sampled, is maintained at entire cabinet under one stable stationary temperature by box heater ACH-0301.It beats
It opens sampling and manually switches off valve BV02-001, control solenoid valve XY-4751 opens pneumatic shut-off valve XV-4751, reads sample introduction pressure
Table PG-4751 numerical value confirms sample introduction sample pressure within the scope of known sample strain.
Third step, sample are filtered removal of impurities using coarse filter F02-001.Sample is by gasification pressure reducing valve PCV-4751
Decompression, is depressurized to after appropriate pressure and is transmitted to pretreatment system or analysis meter after.
