Description

Smoke and dust detection device

Technical Field

The utility model relates to an environmental monitoring technical field, concretely relates to flue gas smoke and dust detection device.

Background

Fixed source flue gas emissions are a very important aspect of creating atmospheric environmental pollution. In order to know the environmental pollution caused by the emission of the flue gas of the fixed source, the emission of the flue gas of the fixed source needs to be monitored. There are two main monitoring methods at present: firstly, a continuous flue gas emission monitoring system (CEMS) is installed, and a national standard method (manual or semi-automatic) is adopted for monitoring; and secondly, the CEMS is installed to carry out on-line continuous monitoring and is regularly compared by using a national standard method. The national fume emission environment monitoring establishes strict standards and specifications, and according to the specific conditions of the shape, the sectional area and the like of a flue (an exhaust passage), strict requirements and detailed regulations are made on the monitoring position, the point position, the time, the frequency and the sampling action of the fixed source fume pollution emission in the standards of GB/T16157, HJ/T75, HJ/T76, HJ/T373, HJ/T397 and the like. Because the combined sampling pipe is generally 1.5m-3.0m long and even longer, when most of the combined sampling pipe enters a flue to be monitored, manual operation at the rear end of the sampling pipe is very difficult. In the current practical operation, the distance of the sampling pipe entering the flue is controlled, the relative position of the sampling head, the pitot tube hole measuring surface and the airflow, the straightness of the sampling pipe and the verticality of the sampling pipe and the flue wall, the collision prevention of the sampling head and the flue wall and the like all need to be controlled manually, the operation process is high in strength and poor in stability, and the interference of human factors is easy to cause.
