Abstract
This invention relates to a device for treating black liquor of paper-making in water-treatment for environmental protection, and an electrolytic bath with cathode and anode chambers partitioned by ionic membrane is provided, a circulation pipe and a flushing pump are set up on the elevated position and in the bottom of anode chamber respectively, and a dreg scraper is set up on the top of anode chamber. It is simple in structure, low in invested cost and not limited in scale, and the electrolytic treatment method renders good effect.
Description
The present invention relates to a kind of environmental protection water technology, especially a kind of treatment unit of black liquid.
Development along with paper industry, the environmental pollution that bring in the paper mill becomes distinct issues, the black liquor of 90-95% from boil house arranged in the pollutent of paper mill, processing to black liquor is to carry out special disposal between the alkali recovery vehicle to set up at present, but the facility investment of this kind facture is big, and be primarily aimed at the processing of wood pulp papermaking black liquor, very different to the treatment effect of black liquid of straw pulp paper-making, have certain limitation.
The objective of the invention is to overcome above-mentioned technology defective, a kind of treatment unit of simple in structure, cost is low, vegetation slurry all is suitable for black liquid is provided.
The present invention adopts treatment with electrolytic method, be provided with electrolyzer, and by ionic membrane every being set as the negative and positive chamber, indoor anode and the negative electrode of being provided with respectively, high position in positive chamber is provided with the effluent cycle outlet, is provided with over against the import of anodic effluent cycle in the bottom of positive chamber, and the effluent cycle export and import is communicated with swash of wave pump by the effluent cycle pipe, simultaneously, at the top of cloudy chamber slag scraping device is set.
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Accompanying drawing is the structural representation of present embodiment.
Present embodiment is provided with electrolyzer (1), and by ionic membrane (2) every being set as the negative and positive chamber, indoor anode (3) and the negative electrode (4) of being provided with respectively, high position in positive chamber is provided with effluent cycle outlet (5), in the effluent cycle import (6) of the bottom of positive chamber setting over against anode (3), effluent cycle outlet (5) and import (6) are communicated with swash of wave pump (8) by effluent cycle pipe (7), simultaneously, at the top of positive chamber (3) slag scraping device (9) are set.When adding black liquor, the anode chamber injects clear water when handling black liquid to cathode compartment, when water level reaches certain degree, can connect power supply and carry out electrolysis treatment, organism part in the black liquor after the electrolysis treatment of certain hour in the anolyte compartment can resolve into the spumescence come-up, then coagulative precipitation of part is arranged, with the continuous impact of swash of wave pump and sewage by the circulation tube continuous work of circulation and slag scraping device continuously, make that large amount of organic obtains removing, it is clear that water quality becomes, and can obtain certain density alkaline solution at cathode compartment simultaneously.
The present invention is simple in structure, reduced investment, and cost is low, and scale do not limit, and the vegetation slurry all is suitable for, and is a kind of more satisfactory black liquid facture.
Claims (1)
1, a kind of treatment unit of black liquid, it is characterized in that: be provided with electrolyzer (1), and by ionic membrane (2) every being set as the negative and positive chamber, indoor anode (3) and the negative electrode (4) of being provided with respectively, high position in positive chamber is provided with effluent cycle outlet (5), and the effluent cycle import (6) over against anode (3) is set in bottom, positive chamber, and effluent cycle outlet (5) and import (6) are communicated with swash of wave pump (8) by effluent cycle pipe (7), simultaneously, at the top of positive chamber (3) slag scraping device (9) is set.
