RB-LP Double tube Ringman Blackness Meter

1、 Introduction: The RB-LP dual tube Ringman blackness meter is a specialized instrument used by environmental protection departments and industrial and mining enterprises to monitor environmental pollution and energy conservation. It complies with the national standard "Determination of blackness of flue gas emitted from fixed pollution sources - Ringman blackness chart method" (HJ/T398-2007). This instrument converts the monitoring of smoke and dust from the daily measurement method of Ringman smoke concentration map to remote measurement through high-quality prism telescopes. Therefore, it has a series of advantages such as small size, large field of view, long distance measurement, fast speed, high accuracy, easy portability, and easy mastery. It is an ideal instrument for monitoring the blackness of smoke and dust. 2、 Main parameters: 1. Telescope magnification: 10x. 2. Telescope objective aperture: 50mm. 3. Measurement distance: 0-500m. 4. Ringman blackness level: 0, 1, 2, 3, 4, 5. 5. Visual observation error: not greater than 0.5. 3.

Brief introduction

RB-LP Double tube Ringman Blackness MeterIt is a specialized instrument used by environmental protection departments and industrial and mining enterprises to monitor environmental pollution and energy conservation. It complies with the national standard "Determination of Blackness of Fixed Pollution Source Emission Smoke by Ringman Smoke Blackness Chart Method" (HJ/T398-2007).

This instrument converts the monitoring of smoke and dust from the daily measurement method of Ringman smoke concentration map to remote measurement through high-quality prism telescopes. Therefore, it has a series of advantages such as small size, large field of view, long distance measurement, fast speed, high accuracy, easy portability, and easy mastery. It is an ideal instrument for monitoring the blackness of smoke and dust.

2、 Main parameters

1. Telescope magnification: 10x

2. Telescope objective aperture: 50mm

3. Measurement distance: 0-500m

4. Lingman Blackness Levels: 0, 1, 2, 3, 4, 5

5. Visual observation error: not greater than level 0.5

3、 Structural principle

This instrument adopts a binocular prism telescope system, with corresponding grayscale step blocks at levels 1-5 of the Ringman smoke concentration map made on the telescope reticle. The fully transparent part is at level 0. The observer compares the smoke target with the grayscale step block through the left eyepiece of the telescope to determine the standard level of smoke blackness.

4、 Usage method

Take out the instrument from the leather bag, degas the eyepiece cover and objective cover, then align the instrument with the monitored chimney mouth, adjust the telescope to make the black smoke emitted from the chimney mouth clear, and then compare and determine.

When measuring, the following points should be noted:

1. The illumination light during observation (i.e. direct sunlight or illumination from the sky) should be side light, approximately at a right angle to the line of sight, and should avoid frontal light and backlighting;

2. In cloudy and foggy conditions, due to the dark background of the sky, readings should be taken at a slightly lower level;

3. There should be no dark obstacles such as mountains, trees, or buildings on the background of the chimney exit;

4. When observing, the boiler should be in normal operation, and the boiler load should be kept above 80% of the rated load. At this time, water should not be added to the coal, and excessive air blowing should not be used for balance release;

5. Observation cannot be based on one time, and the interval between each observation can be controlled between 0.1-1 minutes. Record the data in sequence (instantaneous blackness for each observation), such as when the smoke and dust blackness is between level 2, it can be estimated to be 1/2 level blackness. Finally, take the average of the measured values

The value is the blackness of the smoke and dust.
