Description

Technical Field

[0001] This utility model relates to the field of dust concentration measurement technology, and in particular to a dust heating system for a dust concentration measurement device. Background Technology

[0002] A light-scattering dust concentration measuring device is a tool that measures the concentration of dust in the air based on the principle of light scattering. When airborne particles pass through a laser beam, they scatter light. The device uses a photoelectric sensor to detect the intensity of this scattered light, thereby calculating the dust concentration. However, in a humid flue gas environment, the dust contains moisture. This moisture alters the physical properties of the particles, such as density and refractive index, thus affecting the intensity and direction of the scattered light. This significantly impacts the measurement results, leading to a decrease in measurement accuracy.

[0003] Currently, existing light scattering dust concentration measurement devices typically do not have the capability to directly heat the flue gas to remove moisture from the flue gas dust, thus eliminating the influence of humidity on the measurement results. Utility Model Content

[0028] In an exemplary embodiment of this application, the dust heating system of the dust concentration measuring device includes a measuring chamber 1, an optical path measuring module 2, an air inlet pipe 3, and an exhaust pipe 4. The air inlet pipe 3 is used to introduce flue gas from the flue into the measuring chamber 1, the exhaust pipe 4 is used to discharge the flue gas from the measuring chamber 1, and the optical path measuring module 2 is used to measure the dust concentration of the flue gas in the measuring chamber 1. The dust heating system includes:

[0029] Mounting base 5 is provided with a first channel 501 and a second channel 502. The first channel 501 is connected to the intake pipe 3 and the second channel 502 is connected to the exhaust pipe 4.

[0030] The dehumidification and heating module 6 is mounted on the mounting base 5 and is used to heat the flue gas in the first channel 501.

[0031] In this embodiment, the first channel 501 on the mounting base 5 connects to the air intake pipe 3, and the second channel 502 connects to the exhaust pipe 4. A dehumidification and heating module 6 is provided on the mounting base 5. The dehumidification and heating module 6 heats the flue gas entering the measuring chamber 1 through the first channel 501 of the mounting base 5 from the air intake pipe 3, removing moisture from the dust particles in the flue gas, effectively improving the accuracy of the measurement results and the measurement precision of the dust concentration measuring device.

[0032] In an exemplary embodiment of this application, the dehumidification heating module 6 includes a heating block 601 and a heating rod 602. The mounting base 5 is provided with a mounting channel 503 parallel to the first channel 501. The heating rod 602 is disposed in the mounting channel 503, and the heating block 601 is disposed on the mounting base 5.

[0033] In this embodiment, by installing the heating rod 602 in the installation channel 503, the heating rod 602 is arranged parallel to the first channel 501, so that the heating rod 602 can heat the flue gas passing through the first channel 501 within a certain length range along the axial direction of the air inlet pipe 3; the heating block 601 is arranged above the first channel 501, and the heating block 601 heats the mounting base 5, and then conducts heat to the first channel 501 through the mounting base 5, thereby heating the flue gas in the first channel 501; the combination of heating rod 602 and heating block 601 to heat the flue gas in the first channel 501 can effectively remove the moisture in the dust particles of the flue gas entering the measuring chamber 1, avoid the influence of dust particle humidity on the measurement results, and improve the accuracy of the measurement results.

[0034] In an exemplary embodiment of this application, the intake pipe 3 includes a guide section 301, a detachable section 302, and a fixed section 303. The detachable section 302 is detachably connected between the guide section 301 and the fixed section 303, and the fixed section 303 is connected to the first channel 501.

[0035] In this embodiment, when dealing with working conditions where the measurement points are far apart, the length of the air inlet pipe can be extended by replacing the detachable section 302, making the dust concentration measuring device more flexible and scalable, meeting the needs of multiple working conditions, and effectively improving the compatibility of the device.

[0036] In an exemplary embodiment of this application, a drain pipe 7 is provided on the fixed section 303, and the drain pipe 7 is connected to the first channel 501.

[0037] In this embodiment, the drain pipe 7 is arranged perpendicularly to the fixed section 303 and the opening faces downward, so that the flue gas dust particles can be discharged after the water evaporated by the dehumidification heating module 6 is condensed.

[0038] In an exemplary embodiment of this application, the drain pipe 7 is provided with an installation groove 701, which is used to install a plug 8, and the plug 8 is threadedly connected to the installation groove 701.

[0039] In this embodiment, the plug 8 is used to block the drain pipe 7. The plug 8 is opened periodically to drain the liquid, preventing the drain pipe 7 from leaking out of the flue gas.

[0040] In an exemplary embodiment of this application, the plug 8 is provided with a positioning groove 801, which is used to position and install the sealing component 9, and the sealing component 9 is used to seal the connection between the drain pipe 7 and the plug 8.

[0041] In this embodiment, the sealing component 9 includes, but is not limited to, the use of an O-ring seal. The sealing component 9 seals the connection between the plug 8 and the drain pipe 7, thereby effectively ensuring the sealing performance of the drain pipe 7.
