A synchronous flue gas sampling system and method thereof

Abstract

The invention discloses a synchronous fume sampling system and a method thereof. The synchronous fume sampling system comprises a fume mixing collector, wherein a plurality of fume inlet tubes are communicated with the lower end of the fume mixing collector; a peristaltic pump is connected with the fume inlet end of each fume inlet tube through a hose; the other end of each peristaltic pump is connected with a fume sampling tube through a filter by using the hose; fume can be introduced into the another end of the fume sampling tube; the end part of the fume sampling tube corresponds to a preset measuring point position of a sampling plane; a fume outlet is formed in the top end of the fume mixing collector; a fume discharge valve is arranged at the top end of the fume mixing collector; the fume outlet is connected with a fume analyzer; each peristaltic pump is connected with a driving shaft of a same speed adjusting drive. As the flow of different fume sampling tubes is kept accordant constantly, and the sampling flow is matched with the testing flow of the fume analyzer, the fume sampling measurement accuracy can be ensured.

Description

A synchronous flue gas sampling system and method thereof technical field The invention relates to the field of flue gas sampling and analysis, in particular to a synchronous flue gas sampling system and a method thereof. Background technique In the production links of industries such as electric power, energy, building materials and metallurgy, large boilers are used to provide power in these productions. Monitoring the efficiency and environmental indicators of boiler equipment is an important means to master the economic and environmental performance of boilers. Among them, boiler flue gas sampling is the basic technical means to monitor boiler performance, and is the basis of various test and detection work. The size of the boiler flue is relatively large, especially for large boilers, the cross section of the flue can reach 10 meters wide and 5 meters deep. To analyze the flue gas composition of such a large cross-section, it is necessary to arrange multiple sampli...

Problems solved by technology

The existing flue gas sampling systems and methods are relatively complex and difficult to implement. Although theoretically feasible, they have not been put into practice.

The existing flue gas sampling methods are to mix the flue gas samples from some sampling points first, and then gradually mix each flue gas sampling is a common method. This method cannot measure the flue gas flow obtained from each sampling point, and the There is an indeterminate difference in flow
