specific Embodiment approach 1

[0041] Specific embodiments 1. The continuous nuclear level monitoring method described in this embodiment is:

[0042] Two detectors are arranged on one side of the tank body 20 to be detected, and the two detectors are arranged in a vertical direction, the upper detector is the upper detector, and the lower detector is the lower detector; on the other side of the tank body 20 to be detected A radiation source is arranged on one side for emitting rays; the two detectors are used for receiving the rays emitted by the radiation source;

[0043] The radiation source and the detector make a one-dimensional linear motion along the vertical direction synchronously;

[0044] The signals collected by the two detectors have three combination states, and the three combination states are respectively:

[0045] State 1: The signal intensity received by the upper detector from the radiation source is greater than the threshold, while the signal intensity received by the lower detector is...

specific Embodiment approach 2

[0062] Embodiment 2. This embodiment is a further limitation of the continuous nuclear level monitoring method described in Embodiment 1. In this embodiment, the heights of the radiation source and the detector are adjusted according to the three combined states, thereby realizing The method of monitoring the level in the detected tank is as follows:

[0063] In state two, control the radiation source and the detector to move downward until the signals collected by the two detectors are state one;

[0064] In state three, control the radiation source and the detector to move upward until the signals collected by the two detectors are state one;

[0065] In state one, keep the positions of the radiation source and the detector unchanged, and take the middle position of the two detectors as the material level.

specific Embodiment approach 3

[0066] Embodiment 3. This embodiment is a further limitation of the continuous nuclear level monitoring method described in Embodiment 1. In this embodiment, the radiation signal emitted by the radiation source is γ-ray.

Abstract

A continuous kernel level monitoring method and a device for realizing the same belong to the technical field of radioactive continuous level detection techniques. The continuous kernel level monitoring method and the device solve the problems of low measuring efficiency, high cost and poor measuring accuracy in the prior art and overcome the technology biases in the conventional similar technologies. According to the invention, a radiation source is arranged on one side of a detected tank body and is used for transmitting rays; two detectors for receiving the rays are arranged on the other side of the detected tank body; the two detectors are arranged in the vertical direction, wherein the upper detector is arranged in the upper position, and the lower detector is arranged in the lower position; the radiation source and the detectors synchronously do a one-dimensional rectilinear motion in the vertical direction; in addition, the heights of the radiation source and the detectors are adjusted according to three combined states of signals that are acquired by the two detectors, so that the level in the detected tank body is monitored. The continuous kernel level monitoring method and the device are especially suitable for continuous level detection in harsh environment, and are particularly suitable for continuous level measurement in toxic, inflammable, explosive, high-temperature and high-pressure harsh environment.

Description

technical field [0001] The invention belongs to the technical field of radioactive continuous level detection. Background technique [0002] Level detection technology plays an important role in the actual industrial production process. Through accurate measurement of the level, the optimal control of the production process can be guaranteed. At present, there are many kinds of level products in the practice of manufacturers, which can be divided into contact measurement and non-contact measurement according to the measurement form. Because of its non-contact and non-destructive measurement, the nuclear level monitoring device does not need to change the inherent shape of the installed tank 20. It is especially suitable for level monitoring in harsh environments. It has the advantages of reliable operation, accurate measurement, and convenient maintenance. In actual work has a very wide range of applications. [0003] At present, continuous nuclear level monitoring instrum...
