Abstract
The utility model discloses a drying agent-free sulfur determination device and belongs to the range of a detection technology of total sulfur content in coal. The drying agent-free sulfur determination device is characterized in that a gas path of the drying agent-free sulfur determination device is composed of a quartz tube, a dust filter, an electrolytic tank, a pressure sensor and an air pump which are connected in series, a gas path detection opening of the pressure sensor is connected with a computer, and the pressure sensor is used for transmitting detected gas path pressure electric signals to the computer; and the detected gas path pressure electric signals are about partial pressures of various gases, and the computer is used for converting partial pressure values of the gases into corresponding gas flow values so as to detect the total sulfur content in a sample. The structure of the drying agent-free sulfur determination device is simplified, and the drying agent-free sulfur determination device is not equipped with a gas drying device or a float flowmeter; the using cost is saved; the flow values can be visually displayed on the computer; and device measurement and control software can perform self diagnose, judge failure causes and give corresponding voice and light prompts, so that the unattended operation effect of the device can be achieved truly.
Description
Technical field
The utility model belongs to full content of Sulphur in coal content detection device scope, particularly a kind of without drying agent sulphur meter.
Background technology
In the ISO of coal quality detecting method, ASTM standard, the test of full content of Sulphur in coal, the survey sulphur method that majority relates to is at present mainly some comparatively advanced measuring methods such as infra-red sepectrometry, X-fluorescence method.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 coulometric titration method degree of correlation mostly is the introduction that coulometric titration is surveyed sulphur method, the analysis of principle, the computing method of electric charge etc.External apparatus manufacturer is seldom used coulometric titration method, mainly produces the sulphur meter based on infrared spectroscopy.
Tradition sulphur surveying instrument is comprised of quartz ampoule, dust filter unit, electrolytic cell, two-stage drying tube, the gentle series connection of pumps of suspended body flowmeter.What this sulphur meter adopted is suspended body flowmeter, suspended body flowmeter can only lead to dry gas while using, therefore traditional sulphur surveying instrument must add in the prime gas circuit of flowmeter the moisture in drying agent removal air body, drying agent generally adopts variable color industrial silicone, making thus traditional sulphur surveying instrument have (1) variable color industrial silicone is consumables, need often to change, increase instrument use cost; (2) while changing variable color industrial silicone, easily cause air-channel system gas leakage, thereby affect instrument test result; (3) shortcoming such as apparatus structure complexity.At present not without relevant bibliographical informations such as drying agent sulphur surveying instrument, gas circuit transformations.
Utility model content
The purpose of this utility model is the sulphur meter for prior art, with drying agent, need often to change, increase instrument use cost and easily cause air-channel system gas leakage, thereby affect the deficiency of instrument test result, propose a kind ofly without drying agent sulphur meter, it is characterized in that, this sulphur meter becomes the gas circuit without drying agent sulphur meter by quartz ampoule, dust filter unit, electrolytic cell, the gentle series connection of pumps of pressure transducer, at a gas circuit detection mouthful connection computing machine for pressure transducer.
The beneficial effects of the utility model are to compare with traditional sulphur surveying instrument, have following some advantage:
1. Instrument Design is simplified, and system does not exist drying device, saves the work that user often changes drying agent, saves use cost;
2. thereby not existing because changing drying agent causes air-channel system gas leakage to affect instrument test result;
3. flow value can show intuitively on computers, and combines together with instrument TT&C software, reduces the observed quantity of user to 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 can really accomplish unmanned; And traditional approach can only require lab technician not leave instrument, Real Time Observation float position guarantees to stop in time experiment when Traffic Anomaly.
Accompanying drawing explanation
Fig. 1 connects schematic diagram without drying agent sulphur meter gas circuit.
Embodiment
The utility model proposes a kind of without drying agent sulphur meter.Below in conjunction with accompanying drawing, the present invention is further described.
Figure 1 shows that without drying agent sulphur meter gas circuit and connect schematic diagram.In figure, without drying agent sulphur meter, gas drier and suspended body flowmeter have been cancelled; 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, at a gas circuit detection mouthful connection computing machine 8 for pressure transducer 7.
Pressure transducer of the present utility model is passed to computing machine by the gas circuit electric pressure signal detecting.This pressure transducer detects the partial pressure that gas circuit pressure is each composition gas in real time, and 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 through air pump 6, discharge.
Claims (1)
1. without a drying agent sulphur meter, 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, electrolytic cell, the gentle series connection of pumps of pressure transducer, at a gas circuit detection mouthful connection computing machine for pressure transducer.
