The technical scheme of the invention is a resource utilization treatment method of Chinese herbal medicine dregs:
①, after the dregs after cooking are discharged, the dregs are firstly extruded by a screw press (1) due to higher water content to achieve the purpose of preliminary dehydration, the extruded wastewater is treated by a biochemical pool (2) to degrade organic pollutants, and then desalination and further removal of other pollutants are carried out by a reverse osmosis membrane system, and the produced water reaches the standard and is recycled;
②, dehydrating the residues in a tower dryer (3) in a convection mode, and treating the odor gas generated in the process by acid-base leaching and a biological filter bed (4) to reach the standard and discharge;
③, crushing the medicine dregs from the tower type dryer (3) by a wet crusher (5), wherein the particle size of crushed materials is less than or equal to 5 mm;
④, conveying the crushed press into a drum dryer (6) through a belt, and carrying out convection heat exchange by introducing hot air through a normal pressure fan (7) to achieve the final dehydration target of the material;
⑤, extruding and granulating the dregs from the drum dryer (6) by a biomass granulator (8), then sending the produced dregs granules into a microwave pyrolysis furnace (9) by a feeding machine for pyrolysis and carbonization, and conveying the biochar to an activation tower (12) to prepare the biomass activated carbon with high added value, wherein the process is full-automatic and sealed;
⑥, sending pyrolysis gas generated in the pyrolysis process to a gas storage cabinet (10) for pressure stabilization and homogenization, then burning by using a burning furnace (11), wherein the generated flue gas is used for preparing biomass activated carbon by a charcoal activation tower (12), the activated tail gas is subjected to dust fall treatment by a bag-type dust remover (16) after passing through a cold air blower (14) for heat exchange and temperature reduction of a preheater (13), the tail gas of the dust remover is converged with preheated air, and a constant pressure fan (15) is used for guiding the tail gas to a drum dryer (6) to be used as a drying heat medium.
