The cost of battalion；The hazard property that sulphur and its sulfide also result in crude oil simultaneously changes.According to the United Nations " about dangerous goods
The recommendation model constitution of object transport " in (UNR TDG) " sour crude oil " clearly define as " concentration is enough to cause from crude oil
The hydrogen sulfide containing petroleum crude oil that the gas given out can cause sucking dangerous ", that is to say, that determine whether that sour crude oil is
Using the concentration of hydrogen sulfide as foundation.
Research about sulfurated hydrogen detection in crude oil has: the Zeng little Lan of BJ University of Aeronautics & Astronautics is by the hydrogen sulfide in crude oil
(H2S) through nitrogen stripping, alkaline hydrogen peroxide sorption enhanced is SO4 2-, ion-chromatographic determination SO4 2-Content, to obtain indirectly
H2The content of S.Zhejiang University, Dalian grand duke's environment measuring Co., Ltd are measured in crude oil and can be escaped using iodimetric titration or modification method
Hydrogen sulfide gas out.Liaoning Import &. Export Inspection and Quarantine Office, The People's Republi discloses patent and " photoelectricity dual signal while detecting
The survey of hydrogen sulfide content theoretically can be achieved in the method and detector of hydrogen sulfide and mercaptan in crude oil ", these methods or patent
It is fixed, but the problems such as do not account for field sampling, it cannot really reflect crude storage, the hazard property in transportational process.
Utility model content
Can be realized the technical problem to be solved by the utility model is to provide one kind can escape sulphur in on-line checking crude oil
Change the device of hydrogen, and can classify to the hazard property of hydrogen sulfide.
The utility model solves above-mentioned technical problem with following technical solution:
A kind of monitoring device of volatile hydrogen sulfide in crude oil, the hydrogen sulfide monitoring device are supplied using internal battery
Electricity, the front end connection sampling air pump of hydrogen sulfide monitoring device, sampling air pump pass through the timing in such a way that active is evacuated of pump line suction nozzle
The mixed gas of monitoring point is quantitatively sucked, mixed gas is first filtered through front end, then through H2Sensor and GPS location sensor,
To which the concentration of hydrogen sulfide change information and location information of monitoring point are transferred to single-chip microcontroller；The hydrogen sulfide monitoring device
It is additionally provided with warning module, warning module is connect by I/O interface with single-chip microcontroller, for prompting H2S concentration over-standard, electricity, operation
And fault condition.
The warning module include exceeded alarm buzzing, exceeded alarm lamp, battery capacity indication lamp, run indicator with
And malfunction indicator lamp；Exceeded alarm buzzing and exceeded alarm lamp are for prompting H2S concentration over-standard, battery capacity indication lamp are used for
Electricity supply is prompted, run indicator is for prompting communication abnormality, and malfunction indicator lamp is for prompting H2Sensor failure and GPS
Position sensor failure.
The single-chip microcontroller model are as follows: STM32L433CCT6.
The utility model, which is applied to arrange net in ship or holding vessel, monitors H2The concentration of S gas changes, and can use wireless
The H that Long-distance Transmission Technologies detect monitoring device2S gas concentration is real-time transmitted to terminal monitoring system, and operator is led to again
The state that Data Analysis Software obtained, analyzed each monitoring device is crossed, H is worked as2When S gas concentration is exceeded or reach a certain threshold value
When early warning immediately, thus the safety of guarantee environment and personnel.The hydrogen sulfide content detection of the utility model is " sampling formula "
Detection does not require complete " absorption " hydrogen sulfide；H2Sensor is easily changed, and can suitably weaken mist environment and high humility ring
Influence of the border to sensor is suitble to field to use, degree of protection IP66, and with good stability and reliability, is subjected to
The data for the multiple monitoring devices being arranged.
