(2) background technology
As everyone knows, in the existing paper-making technique, the waste liquid that the paper mill is discharged is divided into three kinds: the one, and concentrated black liquid, the 2nd, rare black liquor, the 3rd, terminal water.Wherein rare black liquor is to be spurted to jetting storehouse by the slurry from rotary spherical digester, and after the secondary pulp-extruding machine extracted concentrated black liquid, remaining slurry added water and is called rare black liquor by the liquid that the roller extrusion filter extracts again again.Extracting remaining slurry for three times delivers to level band wash hollander and carries out paper.Also contain part fiber and plant material material (alkali lignin etc.) and chemical agent in rare black liquor, its concentration is 2 * 10
4About mg/l, it can not be got rid of as waste material, yet can not directly use again, must carry out the processing of physics and chemical process.At present, also do not handle the suite of equipment of rare black liquor.
(3) technology contents
The purpose of this utility model is that the rare black liquor come-up of a kind of papermaking treatment unit will be provided.This device will be with the less equipment setting, and appropriate lectotype selection and mode of connection are fully brought into play the effect of single unit system effectively, is used for production line with full recovery of clear water that reaches after the processing, recycles materials such as alkali lignin.
Task of the present utility model is finished by following technical scheme, has developed the rare black liquor come-up of a kind of papermaking treatment unit, and it is that rare black liquor storage pool is set behind rare black liquid extraction device.This storage pool is connected in the mixing tank by pump and pharmaceutical pipeline, dosing mouth behind dosing mouth and the pump before on this section pharmaceutical pipeline, successively pump being set, this mixing tank inserts in the Buffer Pool by pipeline, this Buffer Pool inserts floating upward groove by pipeline again, this floating upward groove turns in the equalizing tank by immersion liquid pump and pipeline, and this equalizing tank turns back to the inlet of rare black liquid extraction device by fresh water pump and pipeline.
The described pharmaceutical pipeline of the rare black liquor come-up treatment unit of this papermaking, dosing mouth is by auxiliary tank before the pump that is provided with on it, under meter and pipeline turn on the preceding dosing mouth of pump.
The described pharmaceutical pipeline of the rare black liquor of this papermaking come-up treatment unit, it on behind the pump of setting dosing mouth be by the reagent jar, pressure pump, under meter and pipeline turn on behind the pump on the dosing mouth.
The described mixing tank of the rare black liquor come-up treatment unit of this papermaking, it is a turbomixer, or is the baffle-type mixing tank.
The described equalizing tank of the rare black liquor come-up treatment unit of this papermaking, its top also is provided with dosing mouth, and this dosing mouth is by the conditioning agent jar, pressure pump, under meter and pipeline turn on the dosing mouth.
The rare black liquor come-up of this papermaking treatment unit is between described floating upward groove and equalizing tank, and also connecting by sludge pump and pipeline has filter plant.
Described filter plant, itself or oblique net filtration pond, or plate-and-frame filter press.
The described floating upward groove of the rare black liquor of this papermaking come-up treatment unit, itself or be the bottom land liquid-discharing ditch type shallow trough, or be to be provided with the flat tapered shaped can groove of screen cloth.
Advantage of the present utility model is: owing to dosing mouth after on the pharmaceutical pipeline pump being set, turn on the pipeline by reagent jar and pressure pump again on this dosing mouth, make two pumps unify, force the pipeline dosing simultaneously, realize the quick response effect.Behind mixing tank, be connected to Buffer Pool, make reaction solution fully cohesion in this Buffer Pool, insert floating upward groove by pipeline again by pipeline.This floating upward groove is the bottom land liquid-discharing ditch type shallow trough, can realize that materials such as alkali lignin fully condense come-up, are beneficial to the scarfing cinder mummification.This device is with the less equipment setting, and appropriate lectotype selection and mode of connection have fully been brought into play the effect of single unit system effectively, to reach the full purpose that reclaims and recycle materials such as alkali lignin of clear water after the processing.
