Only for 15 minutes, effective absorption unnecessary oil share and remove acne.
While the gas medium is isothermal uniformed, the dissertation calculates the effective absorption coefficient, the Planck-mean absorption coefficient and the wall-incident mean coefficient.
Separate expressions for the transmitted, and multiply diffracted power are obtained, which enable the effective absorption coefficient to be calculated.
The innovation is that a ring bar sprayed bubbling gas distributing device is installed at the bottom of the tower, which has novel effects of leveling off gas and decompressing, cooling and dust removal, highly effective absorption, hydraulic stiring and so on at the same time.
