Description
Technical field
The utility model relates to gas detecting instrument, especially relates to a kind of sulfuretted hydrogen on-line monitoring analyser that can handle, report to the police and transmit the information that detects.
Background technology
Current, petroleum and petrochemical industry, rock gas, chemical industry, iron and steel etc. are to industrialization and automation direction high speed development, and safety problem is a problem demanding prompt solution of these industrial developments all the time.The research that both at home and abroad sulfuretted hydrogen is detected is at present paid much attention to, and detects sulfureted hydrogen gas concentration in real time for ensureing the significant of production safety.
China has obtained remarkable progress in the work of development H table, galvanochemistry and infrared absorption sulfuretted hydrogen comparator and sulfuretted hydrogen alarm have been made in research.Portable sulfuretted hydrogen detection alarm appearance is that various countries use the most general the earliest a kind of concentration of hydrogen sulfide measuring instrument, but the concentration of hydrogen sulfide in detection at any time operation place.
(1) the optics H is to utilize the different principle of gas with various refractive index and the optical assay instrument processed.It is by light source, level crossing, air plenum, gas specimen chamber, refracting prisms, and catoptron and telescope are formed.If the striped that produces when all charging into the fresh air with density with air plenum and sulfuretted hydrogen chamber is benchmark (to zero); When other gas (like sulfuretted hydrogen) gets into the gas specimen chamber; Because of its refractive index is different with air, the light path light path is changed, interference fringe squints; This side-play amount promptly can be used to represent concentration of hydrogen sulfide, and the high more skew of concentration is many more.When the sulfuretted hydrogen chamber charges into the air that contains sulfuretted hydrogen (mensuration of bleeding); Because the density of the H 2 S-containing gas in the fresh air in the air plenum and the sulfuretted hydrogen chamber is different; Cause change of refractive; Light path also just changes thereupon, so interference fringe produces displacement (moving), can see the distance of moving interference fringes from eyepiece.Because the displacement and the concentration of hydrogen sulfide relation in direct ratio of interference fringe; So just can record the concentration of sulfuretted hydrogen according to the displacement of interference fringe; Can observe residing concentration of hydrogen sulfide scale value after the moving interference fringes from eyepiece, so just can record concentration of hydrogen sulfide.
(2) the electrochemical principle detector is according to electrochemical principle work; Utilize gas to be measured electrochemical oxidation process on the working electrode in electrolytic cell; Through electronic circuit that the working electrode and the contrast electrode of electrolytic cell is constant in an appropriate potential; The electrochemical oxidation of gas to be measured can take place under this current potential, and the electric current that gas eletrochemistry reaction to be measured is produced is directly proportional with its concentration.Like this, just can confirm the concentration of gas to be measured through the size of measuring electric current.
The existing hydrogen sulfide detector ubiquity that adopts that power consumption is big, function singleness, shortcoming that precision is not high, and intelligent degree is low, can not handle, store and transmit the information that detects.
Summary of the invention
For overcoming above-mentioned shortcoming, the utility model purpose is to provide a kind of sulfuretted hydrogen on-line monitoring analyser that can handle, report to the police and transmit the information that detects.
The utility model is realized through following technical measures; A kind of sulfuretted hydrogen on-line monitoring analyser; Comprise that pipe connects an extraneous sampling air pump; The sampling air pump meets a sealed air chamber through a dry filter organ pipe, is provided with a gas sensor group in the sealed air chamber, and sealed air chamber is provided with a gas discharge outlet; Said sampling air pump is connected electrically on the processing module through operation circuit; This processing module is electrically connected the gas sensor group through an analog-to-digital conversion module, also is electrically connected with a display module, at least one communication module, an input keyboard and an alarm module on this processing module.
As a kind of optimal way, said gas sensor group comprises hydrogen sulfide sensor, temperature sensor and pressure transducer.
As a kind of optimal way, said communication module is any one or a few the combination in serial communication module, GPRS wireless transport module, cdma wireless transport module, 3G wireless transport module, the USB communication module.
As a kind of optimal way, said alarm module is the sound and light alarm module that hummer and light emitting diode are formed.
As a kind of optimal way, said processing module is the embedded microcontroller based on ARM.
As a kind of optimal way, said analog-to-digital conversion module is AD7927.
The utility model can be effectively to the hydrogen sulfide gas in the various environment monitor, warning and data acquisition and transmission, it is mainly used in multiple place field monitorings such as petrochemical industry coal, chemical metallurgy, municipal combustion gas.
Description of drawings
Fig. 1 is the structured flowchart of the utility model embodiment.
Embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is done further explain.
Like Fig. 1; A kind of sulfuretted hydrogen on-line monitoring analyser, be through sampling air pump 5 with gas extraction to sealed air chamber 13 in, gas from sampling air pump 5 through device for drying and filtering 6 entering sealed air chamber 13; Be provided with hydrogen sulfide sensor probe 9 in the sealed air chamber 13; Also have auxiliary temperature sensor probe 10, pressure transducer probe 11 etc., discharge through gas discharge outlet 12 again after gas is input to and detects in the sealed air chamber 13, form a gas circulation stream and supply to detect.
These hydrogen sulfide gas sensor probe 9, temperature sensor probe 10,11 pairs of gases of pressure transducer probe carry out check and analysis; And convert digital signal to through AD7927 analog to digital converter 8; After conclude, analyze, handle and store, and through LCDs 2 display density data based on the embedded microcontroller 7 of ARM.
