The Cleaning Principle of the present apparatus is as follows：The organic matter and carbon of the composition such as carbon, hydrogen, sulphur are all combustibility things in coal
Matter, although the constituent content of these materials is different in coal, generally all than relatively low, average value is 6 left to atomic number
It is right.Silicon, aluminium, calcium, the oxide of iron and salts substances are to represent incombustible material, i.e. ash content, these yuan in coal ash
All than larger, the average atomic number of ash content is more than 12 to the atomic number of element.
By the above, average atomic number differs by more than 6 or so between combustible and ash content, it is possible to use double source γ
Radiation exposure coal stream, wherein double source include low energy and the middle energy, and low energy is used to detect ature of coal ash content that the middle energy to be used to eliminate
The influence of thickness, density to testing result；Can show that ash content (Ash) is line with the absorption relation (R) of double source by theory deduction
Sexual intercourse, you can draw formula Ash=kR+b (R is the ratio between characterisitic parameter of low energy after being absorbed and the middle energy).So as to
The content of the relatively low combustible species of atomic number is determined that, by being shown in the form of ash content after data processing.
The method of operation of the present apparatus is as follows：The radioactive substance of double source is provided with the radiographic source；The conveyer belt band
Coal sample to be detected is moved by the analytical equipment, when the coal sample moves to the radiographic source and the detector
Between when, radioactive source is opened and simultaneously sends gamma-rays towards the coal sample, and gamma-rays is through the coal sample and by part
Absorb, be then irradiated on the detector, the data is activation that detector will be received to computing module, by computing module according to
Aforementioned calculation method calculates the ash content of coal sample.
