With a simple structure, the automatic sulfur-nitrogen determination instrument provided by the invention well solves the problems of weak data analysis and processing ability and low detection precision in existing sulfur-nitrogen determination instruments, and is convenient for popularization and application.
Description
Technical field
The present invention relates to electrochemical analytical instrument, be specifically related to a kind of sulphur nitrogen automatic analyzer.
Background technology
Sulphur and nitrogen are the essential elements that affects the matter small drums used in the army in ancient China such as oil, rock gas, industrial chemicals, are also the major pollutants of atmosphere.Therefore, the detection tool of sulphur helium concentration is of great significance.The instrument people of existing detection sulphur concentration adopts chemical method more, and equipment complexity, complex operation are subject to the interference of other material toward contact.Therefore, at present the detection of sulfur dioxide concentration is trended towards to the method with physics more, wherein ultraviolet fluorescence method receives much concern because of advantages such as selectivity are good, sensitivity is high.The basic dependence on import of analyser of nitride detects in China, and price is high and difficult in maintenance, is difficult to universal.In general, some problems that at present sulphur blood urea/nitrogen analyzer exists, as: storage holds that Chinese alligator is little, Presentation Function is dull, data analysis processing power shortcoming etc.
Although Chinese patent CN200820217145.7 discloses a kind of sulfur-nitrogen crystalline silica cracking tube, be applied in the analytical instrument with sulphur nitrogen element content in cracking process working sample.This cracking tube stage casing is burning chamber, two ends are respectively gasification end and stabilized end, and gasification end is inner the gasification chamber being connected with carrier gas port, is provided with bending carrier gas economizer bank between described gasification end inwall and gasification chamber outer wall, one end of this economizer bank communicates with gasification chamber, and the other end communicates with carrier gas port.In the time of work, carrier gas is introduced into economizer bank and enters gasification chamber again, carrier gas temperature after preheating reaches the requirement that sample is gasified totally, thereby avoids making because carrier gas temperature is low sample to produce the problem of carbon deposit or residue at gasification chamber wall, and then improves the accuracy detecting.But a little less than it does not solve data analysis processing power completely, the problem that accuracy of detection is not high.
Summary of the invention
The object of this invention is to provide a kind of sulphur nitrogen automatic analyzer, it is not only simple in structure, and a little less than solving existing sulphur apparatus for nitrogen examination data analysis processing power, the problem that accuracy of detection is not high.
The present invention is achieved in that a kind of sulphur nitrogen automatic analyzer, comprises injector, pyrolysis furnace, detecting device, computing machine, and described detecting device is made up of chemiluminescence detector and UV vluorescent tester and signal amplification circuit.
As improvement, described injector is liquid sample feeding device or gas sampler or solid sampler.
As improvement, described pyrolysis furnace is also connected with the membrane dryer of pair of lamina structure.
As further improvement, described computer department divide comprise for showing, storage and the host computer of data analysis processing and the slave computer for injector, pyrolysis furnace, detecting device are controlled, between host computer and slave computer, connect by the communication of USB virtual serial port.
In the present invention, injector, for testing sample is sent into pyrolysis furnace quantitatively, can be selected respectively corresponding injector according to the form that detects sample, has three kinds of models: liquid sample feeding device, gas sampler and solid sampler; Pyrolysis furnace: 1000 DEG C of left and right, the sample being imported by injector is carried out to Pintsch process oxidation, the SOz and the NO that sulphur contained in sample and nitrogen are all converted into can be detected by detecting device; Detecting device: this unit is the core of a whole set of instrument, mainly comprises chemiluminescence detector and UV vluorescent tester and signal amplification circuit, according to the SO being introduced into
2with the concentration of NO, react by physical optics, produce corresponding electric signal, complete constituent content to be measured and change to the correspondence of electrical signal intensity; Computing machine: the electric signal to detecting device output gathers, and carries out data processing by software, finally calculates the concentration of sulphur and nitrogen in sample, and completes the functions such as preservation, printing.Host computer completes the functions such as demonstration, storage and data analysis processing.Industrial PC Computer software and hardware resources is abundant, and technical support is good, and programming is simple, and upgrading is convenient, and can realize friendly man-machine interaction, therefore host computer is selected Industrial PC Computer.Slave computer completes control and the detection to injector, reaction chamber, oxidation furnace, has the input of 9 tunnel analog quantitys, the output of 7 tunnel analog quantitys, 6 way switch amounts and 1 road PWM, and according to the instruction of host computer, to oxidation furnace, the duty of reaction chamber detects and arranges.Meanwhile, the evident characteristic such as the present invention also has simple in structure, and automaticity is high, easy to operate, analyst need only simple training, can carry out the work according to instructions, easy to utilize.
