The main advantages and sampling methods of experimental smoke analyzer

The flue gas analyzer is an instrument for analyzing the smoke content and is widely used by people. Flue gas analysis instruments are mainly used in chemical fertilizers, metallurgy, petrochemicals, cement production, thermal power generation and other industries.

The advantages of the flue gas analyzer are particularly obvious, mainly reflected in:

1. Powerful. Can analyze and test a variety of gas coefficients, selectable differential pressure, flow rate.

2. Complete sampling. The peristaltic pump is automatically switched on and the condensate drains, making it ideal for monitoring and analysis of wet flue gases. At the same time, the instrument is equipped with a three-stage filtration and particle collection device to effectively filter soot particles.

3. Wireless control. The operator controls the operation of the instrument remotely; it avoids operator contamination on site.

4. Strong pumping power. Built-in high-power thin-film air pump, the ultimate vacuum can reach -60kPa, the negative pressure of the flue can still work normally when it is -20kPa.

5. Rapid response. The sampling flow rate of flue gas is 2-3.5 litres/minute to ensure that the sensor is exposed to sufficient smoke and the reaction speed is increased.

6. Reliable and durable. The air pump has superior corrosion resistance.

7. Easy to operate. Use the OK softkey to perform various operations directly.

8. Intuitive display. With a large-screen liquid crystal display, all measurement results are clear at a glance.

9. Easy to carry. AC and DC dual-use, a charge can work continuously for 6 hours, ideal for working in the industrial field.

10. Simple to maintain. With self-diagnosis function, automatically alarm when there is a fault, and point out where the fault occurred. Easy to maintain.

11. Automatic maintenance. When the CO concentration is out of range, the air circuit is automatically disconnected, and the sensor is flushed with a backup air pump to extend its service life.

12. Data records. Instrument built-in 1500 sets of data storage and 1GB MMC memory card, automatically store measurement data, and generate EXCEL format files, the instrument built-in high-speed thermal printer print measurement data at any time.

13. Calculate the average value. User-defined storage time, automatic sampling, measurement, storage and printing of measurement data and the average of a given time period.

14. Match a variety of styles and lengths of probes to ensure accommodating different field test environments.

There are many sampling methods for the flue gas analyzer. The main methods are:

1. Direct suction sampling method (non-dispersive infrared absorption method, ultraviolet absorption method).

2. Dilute suction sampling method (including in-duct dilution and flue dilution).

3. On-line direct measurement method (a beam of infrared light or ultraviolet light is directly irradiated on the flue gas and measured with the characteristic absorption spectrum of SO2).

4. Fixed potential electrolysis.
