| titleOfInvention | A kind of method of brown coal air drying dehydration |
| abstract | The invention provides the method for a kind of brown coal air drying dehydration, said method comprising the steps of: raw material brown coal are pulverized by (1); (2) brown coal after pulverizing are added in soak and soak; Wherein, described soak is the aqueous solution containing dehydrating agent, described dehydrating agent comprises the first dehydrating agent and the second dehydrating agent, wherein, described first dehydrating agent be selected from ferrous salt, hypochlorite, chloramines structural compounds and chlorine monoxid one or more, described second dehydrating agent be selected from carboxylate, sulfuric acid, sulfonate and phosphate ester salt one or more, in described soak, the concentration of dehydrating agent is 0.01 ~ 1 % by weight, and the mass ratio of described first dehydrating agent and the second dehydrating agent is 1:1 ~ 5; (3) brown coal after immersion are sent into dewatering screen to filter; (4) dewater in the brown coal feeding dewaterer after filtration further.The inventive method is safe and reliable, and environmental-protecting performance is high, and energy consumption is low, and flow process is simple, is beneficial to commercial Application. |
