Sampling analysis device with powder filtering filtration function

Abstract

The invention relates to a sampling analyzing device that has dust filtering function. It contains raw filtering module, scrubber, cooler, and refine filter module. The dust would be filtered, and the monitoring action would be taken. It could avoid blocking and uneasy to maintain caused by continuously operation, and effectively improve useful life.

Description

technical field [0001] The invention relates to a sampling and analyzing device, which is used for sampling and analyzing the flue of a combustion system, in particular to a sampling and analyzing device with dust filtering function. Background technique [0002] The sampling system of the traditional flue gas sampling analyzer is installed at the flue gas outlet at the upper end of the chimney, where most of the flue gas has passed through a large dust removal system, such as: electrostatic precipitator, bag dust collector and flue gas desulfurization system, etc., to capture micron dust in the flue gas, so there is no special requirement for the suppression of dust particles required by the sampling system. However, the flue gas value extracted here cannot truly reflect the actual combustion status of the boiler body, which often leads to misjudgment of the operating status of the equipment, resulting in energy consumption and the generation of a large amount of waste gas,...

AI Technical Summary

Problems solved by technology

However, once it is used for a long time or there are multiple sampling points, whether the flow rate of each sampling point pipeline is stable, equal or blocked, whether the flue gas at each sampling point is mixed uniformly, and whether the gas properties are the same often make the long-term sampling and monitoring work difficult. For the sake of impossibility, the sampling port for general real-time optimal adjustment is forced to be moved to the rear of the dust removal equipment or the chimney outlet

This move will also cause problems such as possible leaks in the pipeline and delays in sampling samples.
