Problems solved by technology

[0003] For the usage scenario of the marine flue gas automatic monitoring system, the general sampling probe needs to be equipped with electric heaters, heat preservation covers, and protective boxes, which makes the structure of the sampling probe more complicated
The ship has been sailing at sea for a long time, and the hull swings with the waves. If the probe device is too large and sinks, the connection may break, resulting in failure to sample. The probe is exposed to high humidity and high electrolyte seawater environment for a long time. The frequency of replacement will be very high, which brings great inconvenience to daily maintenance and high cost

Abstract

The application discloses a novel sampling probe, which comprises a probe rod with a through hole, a probe cavity, a probe upper cover, and a filter element. The probe cavity is connected with the probe rod, and the probe cavity is provided with a first flow guide hole; and the probe upper cover is provided with a second flow guide hole. The filter element is arranged on the probe upper cover. Thegas path direction in the heating probe is optimized, and the size of the probe is reduced.

Description

technical field [0001] This application relates to the field of environmental protection, in particular to the detection of gaseous pollutants and particulate matter emitted by air pollution sources. Background technique [0002] The sampling probe is a device connected to the instrument measuring unit of the flue gas measuring device and the chimney. Its function is to collect sample gas with low distortion from the flue gas for measurement of subsequent units. Therefore, the design of the sampling probe plays an important role in the entire detection process. status. [0003] For the usage scenario of the marine flue gas automatic monitoring system, the general sampling probe needs to be equipped with electric heaters, heat preservation covers, and protective boxes, which makes the structure of the sampling probe more complicated. The ship has been sailing at sea for a long time, and the hull swings with the waves. If the probe device is too large and sinks, the connectio...
