Description

Natural y-ray on-line dust meter

Technical Field

Background

The ash detector adopts a double gamma ray penetration method, can eliminate the influence of factors such as porosity, granularity and the like of coal, and quickly detects ash content and heat productivity of the coal. The method is a method commonly adopted by the rapid coal quality on-line analyzer, and the radioactive elements used by the method have the characteristics of low energy level, long service time, small dosage and the like, so that the method is safe and reliable, and the radioactive source does not need to be replaced in the service life. The ash content of coal products must be strictly controlled in order to improve the utilization efficiency of coal, since the coal ash content is closely related to the calorific value of coal. However, the traditional burning test method has complex process and long result lag time, can not adapt to the quality control requirement of coal products, and when the experimental result is obtained, the coal can be produced and put in storage or burned, so that the production and the use can not be rapidly monitored. To solve this problem, new and more scientific methods need to be studied, and new methods for measuring the ash value need to be studied. With the development of science and technology, the company develops a coal quality analyzer using a nuclear physical method, the analyzer adopts a dual-source transmission method, combines a nuclear technology with a computer, can rapidly and nondestructively measure the ash content of coal, controls the coal quality, and timely guides production and performs quality monitoring, thereby improving benefits.

At present, the ash meter of current generally all is direct mount on band conveyer, but because the thickness of material and the homogeneity of ash content distribution are relatively poor on band conveyer, often make to detect that the result is not good and not representative, and the material on the band conveyer is usually thicker in addition, and the low power radiation source can't satisfy the detection demand, must use high-power radiation source, has also increased the degree of difficulty of radiation source radiation protection when increasing the consumption. Therefore, we improve the method and provide a natural y-ray online gray measuring instrument.
