Description
Technical field
The invention belongs to full content of Sulphur in coal content detection technical scope, particularly a kind of without drying agent sulphur meter and survey sulphur method thereof.
Background technology
In ISO, ASTM standard of coal quality detecting method, the test of full content of Sulphur in coal, the survey sulphur method that current majority relates to is some comparatively advanced measuring methods such as infra-red sepectrometry, X-fluorescence method mainly.Other patents relate to and improve sulphur meter degree of accuracy and the scope of application.What most literature related to is principle introduction, and the document higher with the Coulomb equation degree of correlation mostly is the introduction that coulometric titration surveys sulphur method, the analysis of principle, the computing method etc. of electric charge.External apparatus manufacturer seldom uses Coulomb equation, the main sulphur meter produced based on infrared spectroscopy.
Tradition sulphur surveying instrument is composed in series (as shown in Figure 1) by quartz ampoule 1, dust filter unit 2, electrolytic cell 3, two-stage drying tube 4, suspended body flowmeter 5 and air pump 6.What this sulphur meter adopted is suspended body flowmeter, suspended body flowmeter can only lead to dry gas when using, therefore traditional sulphur surveying instrument must add the moisture in drying agent removal air body in the prime gas circuit of flowmeter, drying agent generally adopts variable color industrial silicone, making traditional sulphur surveying instrument there is (1) variable color industrial silicone is thus consumables, need often to change, increase instrument use cost; (2) easily cause air-channel system to leak gas when changing variable color industrial silicone, thus affect instrument test result; (3) shortcomings such as apparatus structure is complicated.Do not have at present without the relevant bibliographical information such as drying agent sulphur surveying instrument, gas circuit transformation.
Summary of the invention
The object of the invention is to propose one without drying agent sulphur meter and survey sulphur method thereof, it is characterized in that, without drying agent sulphur meter without gas drier and suspended body flowmeter; This sulphur meter becomes the gas circuit without drying agent sulphur meter by quartz ampoule, dust filter unit, the gentle series connection of pumps of electrolytic cell, pressure transducer, detect mouth in the gas circuit of pressure transducer and connect computing machine, the airline pressure electric signal detected is passed to computing machine by this pressure transducer.
The described survey sulphur method utilized without drying agent sulphur meter, first puts into quartz ampoule by detection sample coal, heating flame, and produce containing S flue gas, flue gas filters the dust in flue gas through dust filter unit, then enters electrolytic cell, the SO in flue gas
2gas by electrolysis, decomposite S and other gas, then detect airline pressure in real time through pressure transducer, relevant pressure electric signal is passed to computing machine, computing machine is converted to corresponding air flow value according to relevant pressure value, detects sample total sulphur content; From electrolytic cell out mixed gas discharge through air pump.
Described pressure transducer detects the partial pressure that airline pressure is each component gas in real time.
Described computing machine can show gas flow values intuitively, reduce user to the observed quantity of instrument operational factor; And when the electric signal showing flow occurs abnormal, instrument TT&C software self-diagnosable, failure judgement reason, provides mutually at the sound, light prompting, uses instrument really can accomplish unmanned.
The invention has the beneficial effects as follows compared with traditional sulphur surveying instrument have some advantage following:
1. Instrument Design simplifies, and system does not exist drying device, saves the work that user often changes drying agent, saves use cost;
2. do not exist and cause air-channel system leak gas thus affect instrument test result because changing drying agent;
3. flow value can show intuitively on computers, and combines together with instrument TT&C software, reduces user to the observed quantity of instrument operational factor; When there is Traffic Anomaly, instrument TT&C software self-diagnosable, failure judgement reason, provides mutually at the sound, light prompting, uses instrument really can accomplish unmanned; And traditional approach can only require that lab technician does not leave instrument, Real Time Observation float position ensures to stop experiment in time when Traffic Anomaly.
Accompanying drawing explanation
Fig. 1 is that traditional sulphur surveying instrument gas circuit connects schematic diagram.
Fig. 2 connects schematic diagram without drying agent sulphur meter gas circuit.
Embodiment
The present invention proposes a kind of without drying agent sulphur meter and survey sulphur method thereof.Below in conjunction with accompanying drawing, the present invention is further described.
Figure 2 shows that without drying agent sulphur meter gas circuit connection schematic diagram.In figure, eliminate gas drier and suspended body flowmeter without drying agent sulphur meter; This sulphur meter is connected into the gas circuit without drying agent sulphur meter by quartz ampoule 1, dust filter unit 2, electrolytic cell 3, pressure transducer 7 and air pump 6, detect mouth in the gas circuit of pressure transducer 7 and connect computing machine 8, the airline pressure electric signal detected is passed to computing machine 6 by this pressure transducer 7.
Utilize the survey sulphur method without drying agent sulphur meter to be first detection sample coal is put into quartz ampoule 1, heating flame, produce containing S flue gas, flue gas filters the dust in flue gas through dust filter unit 2, then enter electrolytic cell 3, the SO in flue gas
2gas by electrolysis, decomposite S and other gas, airline pressure is detected in real time again through pressure transducer 7, this pressure transducer detects the partial pressure that airline pressure is each component gas in real time, relevant pressure electric signal is passed to computing machine 8 by pressure transducer 7, computing machine is converted to corresponding air flow value according to relevant pressure value, detects sample total sulphur content; From electrolytic cell out mixed gas discharge through air pump 6.
Described computing machine can show gas flow values intuitively, reduce user to the observed quantity of instrument operational factor; And when the electric signal showing flow occurs abnormal, instrument TT&C software self-diagnosable, failure judgement reason, provides mutually at the sound, light prompting, uses instrument really can accomplish unmanned.
