Low-cost deodorizing desiccant and its preparing method

Abstract

The invention provides a kind of low cost deodorization desiccant, the proportion is: coal ash 45-75%, plaster (CaSO4) 18-53%, lime 2-7%. 0.1-0.4 permillage activating agent, the ingredients are: CaO 67-70%, MgO 10-12%, Al2O3 2-5%, SiO2 10-15%, Fe2O3 0.12-0.3%, K2O 0.2-2.5%. Besides, the activating agent also may has other calcium salt, carbon organic compound. Adds 30-45 portions of water into 100 portions of the mixture and forms them into column with radius of 3-10mm, and length of 5-30mm, and then they are dried into products.
