Those enclosed by dotted lines are components in shielded thermostat.Depending on permanent electric dipole moment, CO2, SO2 and other polar molecules have vibrational and rotational structure, and can generate absorption upon coupling with long infrared radiation by incident characteristic wave. Lambert-Beer Law reflects principle of the absorption. II0exp(aPL) I0-incident light intensityI-emergent light intensitya- absorption coefficientP-partial pressure of the gasL-length of analysis bathGiven that CO2 and SO2 have strong absorption band at 4.26mm and 7.4mm, respectively, by measuring light intensity change after absorption, the instrument can analyze percentages of CO2 and SO2, based on which C and S content of measured sample can be established.Analysis room is comprised of infrared source, reflecting mirror, modulation reticle, absorption cell, optical filter and detector. After infrared source rises to 800 upon electric heating, infrared radiation is generated. Optical signal is modulated to 80Hz alternating radiation signal by modulator, for incidence to absorption cell. After absorption by CO2 and SO2 in absorption cell, energy of optical radiations other than the wavelengths above is filtered by narrow band pass filter, followed by incidence of the light to detector, so that light intensities respectively corresponding to concentrations of CO2 and SO2 are detected. Afterwards, they get to be electric signal upon photoelectric conversion, followed by amplification and output of analog quantity signal. Analog quantity signal is converted to C and S percentage upon integral inversion after A/D (analog/digital) conversion and normalization.Analysis flow: for analysis, sample is first weighed on electric balance, followed by result input to microcomputer (or keyboard input), then incorporated with flux and delivered to combustor of high-frequency furnace. The first phase of analysis is oxygen blowing. True solenoid valve is first opened for oxygen input as analysis flow so that residual CO2 and SO2 are removed in pipeline. If contents of CO2 and SO2, as well as partial pressure of measured gas, are 0, reference signal under pure oxygen will be acquired. The second phase is release. High-frequency furnace is started to heat sample to release temperature. At this, sample is immediately oxidized to CO2 and SO2 under high temperature and rich oxygen, and delivered to absorption cell with oxygen acting as carrier. Output signal of amplifier decreases with increase in concentration of measured gas. After normalization, all data is corrected in linearized way. With data from this, percentages of C and S are concluded upon area integration, multiplication by coefficient and blank deduction.Chapter II Instrument StructureCS-206 is comprised of electronic balance, analysis host (AIO comprised of high frequency combustion furnace, infrared gas inspection and gas circuit system), computer and printer. Each part is connected via cable or gas pipe, to complete sample weighing (weight input), combustion (CS oxidation release), measurement, data processing and data (statement) printing.I. Electric balanceWhat is to be achieved is weight percentages of C and S, thus weight value of measured sample from electronic balance is necessary for data normalization. Weight value is directly and automatically input to upper microcomputer via serial port and communication line of balance. Measured object is weighed and combusted in crucible. Treated empty crucible is put on electronic balance. Its weight can be automatically deducted by electronic balance with analysis software. Then, measured object is put in. When balance gets stable, weight of measured object can be automatically input to computer if Enter is pressed. II. Computer Computer supports data acquisition, operational processing, database management, real-time control, man-machine dialog and on-line operation with printer, electronic balance, data transmission unit and other peripheral equipments. Comprised of host, display, keyboard and mouse, computer needs 1 serial port at least. Analysis software of CS-206, which is installed under root directory of disk C, needs support by Windows 2000 or Windows XP. III. Analysis hostAnalysis host is comprised of high frequency heating equipment, gas circuit system, CS signal detection system and control unit. Measured sample is heated and combusted to release CO2 and SO2, and delivered to inspection system after dedusting and drying.1. Front view1. Grid current meter2. Plate current meter3.
