Background
Smoke sampling is an important link in smoke emission, equipment performance test and environmental protection supervision. When the smoke content of the measuring point after the dust removing, desulfurizing and denitrating equipment is sampled, a smoke sampling device is needed. According to the national relevant standard, the sampling position is required to be determined according to the flue size during the flue dust sampling, for example, when the flue dust with a large width is sampled, a plurality of sampling point positions exist in the same radial direction, so that the length of the sampling gun is strictly required. However, the overlong sampling gun is not beneficial to processing and ensuring the strength of the gun body, is not convenient to adjust in time according to the size of the wide flue, and is not easy to transport due to the limitation of the field.
Traditional smoke and dust sampling uses a glass fiber filter cartridge to collect smoke and dust, and when dry smoke and dust sampling is carried out, the filter cartridge is fragile due to overhigh smoke temperature. Many pieces are generated and left behind when the cartridge is removed, so that measurement deviations occur when the cartridge is weighed; when wet flue gas and smoke dust are sampled, because the temperature difference between the inside and outside of the sampling gun is large, the moisture in the wet flue gas is condensed and then mixed with the smoke dust and acidic substances in the flue gas, the inside of the sampling gun can be corroded, even the air passage is blocked, and meanwhile, the sampling filter cylinder is also made to become wet and soft and even broken, so that the weighing of the filter cylinder after the smoke dust sampling is influenced.
