GB/T 15187-2017 in English

Analysis of the core content of the standard

GB/T 15187-2017, as the national standard for the performance measurement of wet dust collectors, systematically regulates the test method system for wet dust collectors. Compared with the 2005 version, the main technical evolution is reflected in:

Detailed explanation of key measurement technologies

1. Sampling system construction

The standard requires the establishment of a three-level quality control system:

1. Measurement point arrangement: The circular flue adopts the equal area integral ring method. When the diameter is greater than 4m, 10-20 measurement points need to be arranged
2. Instrument selection: Pitot tube coefficient error ≤2%, temperature measurement accuracy ≥ Level 1
3. Working condition control: The dust concentration needs to be stable in the range of 1-20g/m³ during the test

2. Core parameter measurement

Implementation suggestions

1. On-site operation specifications

Note when performing dust concentration measurement:

• The sampling gun heating temperature needs to be controlled at 160±5℃
• The constant weight of the filter cartridge requires the difference between two weighings to be ≤0.3mg
• The SO2 absorption liquid needs to be kept in an ice bath at ≤25℃

2. Data quality control

3. Special working conditions processing

For high humidity flue gas (moisture content＞15%vol):

1. Condensation method is preferred for humidity measurement
2. The sampling system needs to add an insulation sleeve
3. Gas density needs to be corrected during calculation (Formula 13)
