Description

Technical Field

[0001] This utility model relates to the field of flue gas testing technology, specifically to a flue gas testing device. Background Technology

[0002] Automatic flue gas (smoke and dust) testers are a type of environmental monitoring instrument, mainly used for monitoring the emission concentration, equivalent concentration, and total emission of flue gas from various boilers and industrial furnaces.

[0003] In the prior art, an automatic dust and flue gas tester suitable for low-temperature environments in frigid regions, with publication number "CN 210514222 U", belongs to the field of environmental monitoring instrument technology. It includes a main unit, a sampler, a temperature-controlled heating cable, a connecting hose, and a temperature-controlled heating hose. The main unit and sampler are connected via the connecting hose. A temperature-controlled heating hose is fitted over the connecting hose to maintain its temperature, and this hose is connected to the temperature-controlled heating cable for temperature regulation. In frigid environments, the temperature-controlled heating cable wraps around the connecting hose to prevent moisture in the flue gas from condensing and freezing, thus preventing blockage. This invention has a simple structure and can ensure that the automatic dust (gas) tester can operate for extended periods in frigid environments, preventing moisture in the flue gas from condensing into ice and blocking the connecting hose, thus ensuring smooth testing and accuracy.

[0004] However, the aforementioned patents lack a temperature feedback mechanism, meaning the temperature control heating element may not accurately control the temperature, leading to excessively high or low temperatures in the connecting hose. Excessive temperature may affect the integrity of the flue gas sample, while excessively low temperature may still cause condensation. Utility Model Content

After the flexible heating layer is wrapped around the connecting hose, its two sides are connected by Velcro. The temperature measuring component includes a temperature sensor, which is fixedly disposed on the inner side of the flexible heating layer and attached to the outer wall of the connecting hose.

[0007] In a preferred embodiment, the flexible layer is a fabric, and the two fabric layers are fixed together by adhesive or sewing.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] A flue gas testing device includes: a main unit 10, a sampler 20, a connecting hose 30, a heating module, and a temperature measuring component.

[0017] The heating module is sleeved on the connecting hose 30 and includes a flexible heating layer 401, a power module, and a switch. The flexible heating layer 401 is wrapped around the connecting hose 30. The power module and the switch are located on the main unit 10. The flexible heating layer 401 includes two flexible layers 4011, with an electric heating wire 4012 sandwiched between the two flexible layers 4011. The electric heating wire 4012 is connected to the switch and the power module to form an electrical circuit. After the flexible heating layer 401 is wrapped around the connecting hose 30, its two sides are connected by Velcro, which makes it easy to wrap the flexible heating layer 401 around the connecting hose 30 and easy to disassemble.

[0018] The temperature measuring component includes a temperature sensor 501, which is fixedly disposed on the inner side of the flexible heating layer 401 and attached to the outer wall of the connecting hose 30, for real-time monitoring of the surface temperature of the connecting hose 30.

[0019] The heating wire and temperature sensor 501 provide feedback, enabling precise heating of the connecting hose 30. This ensures that the connecting hose 30 is at a suitable temperature, preventing freezing and avoiding excessive heat that could lead to energy waste.

[0020] In a preferred embodiment, the flexible layer 4011 is a fabric, and the two fabric layers are fixed together by adhesive or sewing.

[0021] In a preferred embodiment, the outer surface of the flexible heating layer 401 is provided with an insulating and heat-preserving layer 402, which effectively reduces the loss of heat to the environment.

[0022] In a preferred embodiment, the insulating layer 402 is an aerogel composite material or a foam ceramic material, and its outer surface is provided with a waterproof coating.

[0023] In a preferred embodiment, the temperature sensor 501 is a PT100 platinum resistance sensor, and there are at least two of them, arranged at intervals along the length of the connecting hose 30. Using multiple temperature sensors 501 for multi-point heating achieves precise and uniform heating of the entire length of the connecting hose 30, effectively preventing localized icing or overheating.
