Description

Technical Field

[0001] This utility model relates to the technical field of portable flue gas detectors, and specifically to a flue gas detection device with filtration and separation. Background Technology

[0002] A flue gas analyzer is a device that uses electrochemical sensors to continuously analyze and measure the content of CO2, CO, NOx, SO2, and other flue gas components. It is mainly used for handheld environmental monitoring of small oil-fired and gas-fired boiler emissions or near pollution sources. Based on usage, it can be divided into handheld flue gas analyzers and fixed, wired recording flue gas analyzers. When using a flue gas analyzer, because it primarily collects flue gas, there is a risk of the inlet pipe becoming clogged with particulate matter, especially in harsh environments such as coal mines or areas with high dust levels, leading to data errors. Therefore, this paper proposes a flue gas detection device with filtration and separation capabilities. Utility Model Content

[0028] The portable flue gas detector 1 includes a detector body 11, a protective shell 13 covering the outside of the detector body 11, and an air inlet 12 connected to the detection port of the detector body 11.

[0029] The air intake filtration and separation mechanism 2 includes a middle section housing 21, a rear section housing 29 fixed at the rear end of the middle section housing 21, and a front section housing 27 fixed at the front end of the middle section housing 21. A servo fan 28 is fixedly installed in the inner cavity of the rear section housing 29. A filter plate 25 is snapped into the inner cavity of the front section housing 27. An air intake pipe 26 is fixedly connected to the front end of the front section housing 27.

[0030] The small particulate dust filter assembly 3 includes an inner tube 31, a mesh plate 33 fixedly connected to the front and rear ends of the inner tube 31, and degreased cotton 32 filled in the inner cavity of the inner tube 31.

[0031] The front end of the middle section housing 21 is fixedly connected to an externally threaded tube 22 inserted into the rear end of the front section housing 27. The rear end inner wall of the front section housing 27 is provided with threads, and the outer surface of the externally threaded tube 22 is provided with threads. An inner ring 24 is fixedly connected to the front end of the inner cavity side wall of the front section housing 27. The edge of the front end face of the filter plate 25 contacts the rear end face of the inner ring 24. A C-shaped handle 23 is fixedly connected to the rear end face of the filter plate 25. The rear end face of the C-shaped handle 23 contacts the front end of the externally threaded tube 22. The inner cavity side wall of the rear section housing 29 is fixedly connected to the four corners of the outer shell of the servo fan 28 by screws.

[0034] When conducting flue gas testing in harsh environments, such as coal mines or other dusty environments, the servo fan 28 is activated to draw external gas into the intake pipe 26 and the front housing 27. At this time, the gas will pass through the filter plate 25 to remove some particulate matter. After passing through the filter plate 25, the gas enters the inner tube 31. The degreased cotton 33 at the front and rear ends of the inner tube 31 further filters the particles in the gas. In addition, the gas will pass through the mesh plate 32, which adsorbs and separates the moisture in the gas. After being filtered and dried by the mesh plate 32, the gas is delivered to the air inlet 12 for testing.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
