[0002] At present, there is no effective real-time detection method for the material level of the desulfurization and denitrification silo. The method of adding materials by estimating the material consumption or regular manual inspection is used to determine the silo situation. The material level cannot be monitored online in real time. For early warning material level , The alarm material level cannot be detected in real time, the remaining amount of the material in the silo cannot be accurately grasped, and it is even impossible to count the material data according to the daily material consumption. status assessment

Embodiment Construction
[0023] The present invention will be further described below in conjunction with the drawings and embodiments.
[0024] Such as figure 1 As shown, the installation schematic diagram of the desulfurization and denitrification material flow rate and margin detection device of the present invention is given. The detection device 3 shown is installed at the center position of the top of the silo, so that the detection device 3 measures 3 through the 3D radar probe The distance in the direction, as shown in the figure, the distance in the x, y and z axis directions, the distance in the x and y directions is the distance between the silo 1 wall in the horizontal plane where the 3D radar probe 13 is located and perpendicular to each other. The distance of the 3D radar probe 13 in order to find the cross-sectional area of the silo 1. The distance along the z-axis direction is the distance between the upper surface of the material 2 and the 3D radar probe 13 through which the remaining ...

In the 3D radar-based desulfurization and denitrification material flow rate and residual detection device of the present invention, the detection device is composed of an outer shell and a circuit part; the outer shell is provided with a key module, a liquid crystal display and a communication interface; the feature is that the circuit part is processed by data And control unit, 3D radar probe and communication module, the data processing and control unit obtains the distance in three directions required to measure the material flow rate and margin through the 3D radar probe. The detection methods include: a). Equipment installation; b). Collecting the width in the horizontal plane and in two directions; c). Judging the shape of the silo; d). Calculating the cross-sectional area; e). Calculating the material flow rate; f). Calculate the material balance; g). Judgment whether the warning value is reached; h). Calculate the usable time of the material. The device and method for detecting the flow rate and the remaining amount of the present invention well solve the existing weaknesses of unreliability caused by human factors and poor real-time detection, and better guarantee safe production.
Description
Technical field [0001] The present invention relates to a 3D radar-based desulfurization and denitrification material flow rate and residual detection device and method, and more specifically, to a 3D radar-based desulfurization and denitrification material flow rate and method that can adaptively accurately monitor a silo Surplus detection device and method. Background technique [0002] At present, there is no effective real-time detection method for the material level of the silo for desulfurization and denitrification. The material level of the silo is determined by adding in the way of estimating the materials or manually checking the method on a regular basis. The material level cannot be monitored online in real time. , The alarm material level cannot be detected in real time, and it is impossible to accurately grasp the remaining amount of the silo material, and it is also impossible to count the material data according to the daily material consumption. These important d...
