Problems solved by technology

[0007] 1. The safety of the γ-ray source is poor. Once the ray source is lost or leaked, it will cause great harm to the environment or people
[0008] 2. Due to the poor safety, the γ-ray source must be strictly managed, and it needs to pay a large management fee every

Embodiment Construction

[0047] The specific implementation of the present invention will be described in detail below through specific embodiments.

[0048] The invention uses X-rays instead of gamma rays, so that the measurement process has good safety, high accuracy, simple structure and high reliability. And based on the thickness (or weight) correction of the object to be measured, the ash content measurement is performed to improve the accuracy of the ash content measurement.

[0049] see Figure 1A Shown is a schematic structural view of the X-ray ash measuring device 100 of the present invention. The X-ray ash measuring device 100 includes a thickness measuring device 1, an X-ray source 2, m (m=1, 2, 3...m) X-ray detectors 6, a measuring container 4, a measured object 3, and a data processing unit 5. Rotating platform (or stationary platform)7.

[0050] The measuring container 4 is placed on the rotating platform 7 , and the measured object 3 is set in the measuring container 4 . The object...

Abstract

The invention discloses an X-ray ash content measurement device and method. The device comprises a measurement container, a static platform and a rotation platform, an X-ray source, m (m=1, 2, 3,...m) X-ray detectors, a thickness measurement, a weight measurement device and a data processing device, wherein the measurement container is provided with a detected object; the measurement container isarranged on the static platform and a rotation platform; the X-ray source is used for emitting the X-ray to irradiate the measurement container; m (m=1, 2, 3,...m) X-ray detectors are used for receiving the X-ray penetrating through the detected object and converting the ray into a detection signal; the thickness measurement device is used for measuring a thickness value of the detected object, or the weight measurement device is used for measuring a weight value of the detected object; the data processing device is used for computing a coal ash content value according to an electric signal and the thickness value or according to the electric signal and the weight value; and the data processing device computes the coal ash content value according to the following mathematic models as shown in the specification.

Description

technical field [0001] The invention relates to an ash content measurement and control technology, in particular to an analysis and measurement device and method for realizing ash content by using X-rays. Background technique [0002] Coal generally consists of two parts, one is a combustible substance composed of carbon, hydrogen, sulfur, etc., and the other is an incombustible substance composed of oxides such as calcium, aluminum, silicon, and iron. [0003] Coal ash is the weight fraction (ie weight percentage) of incombustible substances—that is, oxide residues—after coal is fully and completely burned at a certain temperature. [0004] The ash content of coal is closely related to the calorific value of coal. In order to improve the utilization efficiency of coal, the ash content of coal products must be strictly controlled. [0005] At present, coal ash measurement methods include X-ray fluorescence analysis, backscattering method, high-energy γ-ray annihilation radi...
