Description
Technical Field
The utility model belongs to the technical field of the chemical industry, concretely relates to brown coal high frequency drying device and forming process.
Background
The low-rank coal is mainly characterized by high water content (50-65%), low calorific value and high volatile content, and lignite, particularly young lignite, often contains rare resources such as montan wax, humic acid, germanium and the like. In any case, dehydration is firstly carried out, the main purpose of drying is to reduce the amount of process wastewater, and water resources can be recovered in the drying and dehydration process. The conventional drying equipment adopts a rotary dryer, and the heating equipment adopts a boiling hot blast stove which is a coal and gas co-combustion hot blast stove. The energy consumption of the lignite containing 50% of moisture is about 200Kg per ton of dry-basis lignite (5000 kcal), so that the conventional drying method has high energy consumption and large carbon dioxide emission, and has certain influence on the environment.
