Product summary: Kdtq-3a three section furnace coal hydrocarbon element analyzer is mainly used to determine the content of carbon and hydrogen in coal and other organic matter. A certain amount of samples are burned in oxygen flow, and the water and carbon dioxide generated are absorbed by water absorbent and carbon dioxide absorbent respectively. The carbon and hydrogen contents in coal are calculated by the increment of absorbent. The performance of the instrument meets the requirements of GB / T 476-2001 method for elemental analysis of coal. The instrument is simple to operate, quick to determine and accurate in results. It can be used in laboratories of coal, chemical, metallurgical, electric power and geological exploration departments.

Kdtq-3a three section furnace coal hydrocarbon element analyzer
The instrument is composed of a high temperature furnace, a temperature controller, a gas purification and absorption device. Each furnace is separately controlled by an independent control system for temperature indication and constant temperature control. The temperature display is controlled by a high integrated digital temperature control meter, with an accuracy of 0.5 level

Instrument maintenance
1. The instrument should be protected from dust and corrosive gas, and should be used in a dry environment.
2. The instrument should be handled with care to prevent vibration damage.
3. Pay attention to the protection and cleaning of the electrolytic cell. If the hydrogen value of the system is found to be low, if there is no other error, the electrolytic cell should be treated.
4. Replace silicone rubber tube and gasket regularly.
5. If it is not used for a long time, the electrolytic cell shall be treated and calibrated with standard samples. Generally, the standard samples shall be used for calibration once a month.
6. The air tightness of the system should be checked frequently.
7. Pay attention to check the failure of various Yao products.
?
Test procedure:
1. The temperature of economizer is controlled at 800 ℃, the temperature of the second furnace is controlled at 800 ℃, the temperature of the third furnace is controlled at 600, and the economizer is close to the second furnace.
2. Weigh 0.2g air dried coal sample with particle size less than 0.2mm in the pre burned combustion boat, weigh it accurately to 0.0002g, and evenly spread it. A layer of tungsten trioxide was laid on the coal sample. The combustion boat can be temporarily stored in a special ground glass tube or a dryer without desiccant.
3. Connect the oxygen to the system at a flow rate of 120 ml / min. Open the rubber stopper, take out the copper wire coil, quickly put the combustion boat into the combustion pipe, make its front end just at the furnace mouth, then put the copper wire coil and plug the rubber plug. The oxygen flow rate was maintained at 120 ml / min. After 1 min, move the economizer towards the purification system to make half of the combustion boat enter the furnace; 2 min later, move the furnace to make all the combustion boats enter the furnace; 2 min later, make the combustion boat in the center of the furnace. After holding for 18 min, the furnace is moved back to its original position. After 2min, take down the absorption system and close the grinding plug (when supplying oxygen under negative pressure, close the U-tube grinding plug close to the bubble meter first, then close other U-tube grinding plug in turn, and then take off the absorption system), wipe it with flannelette, place it beside the balance for 10min and weigh it (the nitrogen removal tube is not weighed). The change of the second carbon dioxide absorption U-tube is less than 0.0005g, which is ignored in calculation.
4. In order to check whether the measuring device is reliable, the standard coal sample can be used for determination according to the specified test steps. If the difference between the measured value of carbon and hydrogen and the standard value of carbon and hydrogen of standard coal sample is within the uncertainty range of standard coal sample, it shows that the measuring device is reliable. Otherwise, it is necessary to find out the causes and correct them before formal determination.

Treatment of hydrogen analyzer after electrolysis cell experiment
(1) Remove the cell;
? (2) Clean the electrolytic cell: first, rinse it with tap water, then dip it with a small soft brush with washing powder, slowly turn the brush to the left and inward, pay attention to the lead wire, and then slowly turn the brush outward to exit, wash with water to see if the platinum wire is bright. If there is any black spot, brush it again until it is cleaned, * then rinse it with distilled water, and then rinse it with copper propylene After that, use an electric blower (hot air gear) to dry, and then measure the two poles of the electrolytic cell with a multimeter resistance block (2k). The internal resistance should be infinite, indicating that the cleaning is in good condition, otherwise clean it again.
(3) distribution solution: take 10ml or 15ml small measuring cylinder, according to the volume ratio, first put in 3 parts of phosphoric acid (superior grade pure), and then put in 7 parts of propylene copper. Shake the measuring cylinder gently, and the bottom of the cylinder should have heat dissipation. ?
(4) coating: tilt the rough end of the cleaned cell upward, pour the prepared electrolyte into the cell, and then to 1 / 2 of the length of the cell (if the electrolyte still flows downward, level it and wipe off the flowing electrolyte with filter paper), Then dry it with cold air, pour it into the whole cell for the second time (pay attention not to flow through the two poles), then dry it with cold air, pour half of it into the cell for the third time, dry it with cold air, and then measure the two poles with a multimeter (1 Ω block). If there is a certain resistance value (several or dozens of Ohm), the coating is normal, otherwise repaint.
(5) install the coated electrolytic cell, and put the cooling suit on, so that the fine end of the electrolytic cell is slightly inclined upward.
? (6) Electrolysis: turn on the gas path and the flowmeter displays 80ml / min. turn on the power supply and press the coating key. After 60 minutes of electrolysis to the end point, press the coating key again to continue the coating until the end point (electrolysis current ≤ 70ma). After reaching the end point, press the "month and day" key, press the odd number and even number respectively, and then press the return key to make the electrolysis current quickly drop to the end point. After repeated for many times, it can be used At this point, the treatment of the electrolytic cell is completed, and two waste samples are analyzed to balance the system before making formal samples.
