Description

Technical Field

[0001] This utility model relates to the field of flue gas detection technology, specifically to an assembled detection mechanism with multiple detection points connected in series. Background Technology

[0002] Achieving the "dual carbon" goal requires a two-pronged approach: controlling carbon emissions and increasing carbon absorption. Both aspects necessitate carbon emission measurement, making the measurement methods, accuracy, and suitable instruments crucial. Domestic thermal power plants primarily employ wet desulfurization technology for flue gas. During desulfurization, flue gas temperatures can reach (45–52)℃, containing saturated water vapor and a large amount of corrosive acid ions. Flue gas flow rates are typically (17–30) m / s. Therefore, flue gas flow metering equipment usually operates under high temperature, high humidity, and corrosive conditions.

[0003] Many portable sampling and testing devices in the present technology need to be inserted at different depths to perform multiple single-point tests. Although they are easy to install, they require intervals for testing, which reduces the testing efficiency. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] Please see Figures 1 to 4 This utility model discloses an assembly testing mechanism with multiple detection points connected in series, including an electrical control box 1. A testing component is provided on one side of the electrical control box 1. The testing component includes ultrasonic testing units connected in series. The ultrasonic testing unit includes an ultrasonic testing head 7. At least two sets of ultrasonic testing heads 7 are provided.

[0019] In this embodiment, two or more ultrasonic detection heads 7 installed in series are inserted into the sampling hole 9 on the chimney 10 at one end to detect the flow velocity at different positions at the same time. The multiple flow velocity values ​​are weighted and averaged by the integration unit to obtain a more accurate actual flow velocity, thereby more accurately reflecting the instantaneous flow rate of the flue gas.

[0020] An integrator is installed inside the electrical control box 1, and the integrator is electrically connected to the ultrasonic detection head 7 via a cable.

[0021] It should be noted that the integrator unit is located inside the electrical control box 1 and can work in conjunction with the data collected by the ultrasonic testing head 7 to continuously monitor the output flow rate in real time. The specific data transmission and calculation principles of this part are existing technologies and will not be elaborated further.

[0022] A telescopic connection assembly is provided between adjacent ultrasonic testing units. The telescopic connection assembly includes a sleeve 5 and a screw 6. The inner wall of the sleeve 5 is provided with an internal thread. The external thread and the internal thread of the screw 6 are matched. A locking nut 8 is provided on the surface of the screw 6.

[0023] In this embodiment, a telescopic connecting assembly is connected between adjacent ultrasonic detection heads 7, including a sleeve 5 and a screw 6 threaded into the sleeve 5. According to the specifications of the sampling platform of the chimney 10, the ultrasonic detection heads 7 are evenly arranged on one side of the electrical control box 1. Rotating the screw 6 can adjust the overall length of the sleeve 5 and the screw 6, that is, the distance between the ultrasonic detection heads 7. After determining the length, the locking nut 8 is rotated to lock it.

[0024] It should be noted that the telescopic connection component is the structure in the above embodiments, but is not limited to the structure in the above embodiments, as long as it can realize the position adjustment of the ultrasonic detection head 7.

[0025] The screw 6 is a hollow rod structure, and a cable is installed through the first insert 2, the second insert 4, the sleeve 5 and the screw 6.

[0026] It should be noted that since the ultrasonic testing head 7 and the electrical control box 1 are electrically connected by a cable, the screw 6 needs to be set as a hollow structure, which can not only support the testing device, but also be used for cable penetration and protection.

[0027] A first plug rod 2 is connected to one side of the electrical control box 1, a flange 3 is connected to one end of the first plug rod 2, and a second plug rod 4 is connected between the flange 3 and the ultrasonic testing head 7.

[0028] In this embodiment, a first insert rod 2 is provided to connect the electrical control box 1 and the flange 3. The flange 3 is used to complete the fixed connection with the chimney 10. Depending on the usage requirements, the second insert rod 4 between the flange 3 and the ultrasonic testing head 7 can also be set as a telescopic structure.

[0029] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
