Abstract
The utility model discloses a recycling device for pulping wastewater, which comprises a wastewater pool, a pulper and a multi-disc concentrator, wherein a waste carton soaking pool is arranged aside the wastewater pool; a water-filling pipeline is communicated between the wastewater pool and the pulper; a spraying pipeline is communicated between the wastewater pool and the waste carton soaking pool; a sprayer of the spraying pipeline is arranged above the waste carton soaking pool; a wastewater effusion pipeline is arranged between the multi-disc concentrator and the wastewater pool; and a water pump is communicated with the water-filling pipeline and the spraying pipeline. The recycling device for pulping wastewater has the advantages that: 1) the invested equipment is less, the emission load of the wastewater is effectively controlled and the cost is lowered; 2) the set of closed recycling system is high in use ratio of whitewater, the running cost is low, the water consumption per ton paper is effectively reduced and is reduced to 5-7 tons, and the set of closed recycling system is located in the domestic leading position; and 3) the treating pressure and the treating cost of the wastewater are reduced and the water resource is saved.
Description
Technical field
The utility model relates to field of papermaking, is specifically related to the corrugated paper factory effluent recycle in the field of papermaking.
Background technology
Corrugated paper is a raw material with waste paper, litter decoration etc. generally, through pulping, screening, flotation and copy production processes such as paper and process, in these production processes, all will produce a large amount of waste water.Main Ingredients and Appearance in the waste water is tiny suspension fiber, papermaking filler, waste paper impurity and a small amount of pectin, wax, carbohydrate, and all kinds of organic and inorganic compound that adds in the paper process.Generally, the displacement of ton paper product is at 70～80 cubic metres.At present; The method of both at home and abroad paper waste being handled has: the precipitation method, air supporting method, biochemical process etc.; These methods have played better effect for the pollution that reduces paper waste, but also exist following deficiency: the one, and the abatement equipment investment in fixed assets is big, and is domestic with the precipitation method, air supporting France and Japan processing 5000-10000 ton waste water; It is made an investment in about 2,000,000 yuan, and the biochemical process investment is then bigger; The 2nd, operating cost is higher, and wastewater treatment expense per ton is between 5-7 unit; The 3rd, because ton paper water consumption big (generally between the 20-30 ton), water resource waste is serious.The wastewater flow rate that in size degradation, pulping process, produces of waste paper, litter decoration bigger (waste water of generation per ton is about 60 tons) wherein, it is medium pending that these waste water major parts flow directly into plant area Wastewater Concentrated pond, increased wastewater treatment capacity.
Summary of the invention
The technical problem that the utility model will solve provides a kind of pulp-making waste-water recycle device (referring to that mainly shredded paper, the waste water in this stage of slurrying recycle), and not only equipment investment is few, and operating cost is low, what is more important conserve water resource.
The utility model is realized through following technical scheme:
A kind of pulp-making waste-water recycle device comprises wastewater disposal basin, pulper, polydisc thickener; Be provided with the litter decoration fermentation vat on the wastewater disposal basin side, be communicated with the filler pipe road between said wastewater disposal basin and the pulper, and be communicated with spray piping between the fermentation vat, the shower nozzle of said spray piping is arranged at litter decoration fermentation vat top; Be provided with waste water between said polydisc thickener and the wastewater disposal basin and flow out pipeline; Be communicated with water pump on said filler pipe road and the spray piping.
The further improvement project of the utility model is, the shower nozzle of said spray piping is the annular hollow structure, and it is communicated with spray piping, or shower nozzle is circular straighttube, and the one of which end is communicated with spray piping, and the other end is a blind pipe; Said shower nozzle is provided with some spray orifices.Said shower nozzle is arranged on the support.
The utility model further improvement project is, said filler pipe road, spray piping one end are communicated in pulper, shower nozzle respectively, the other end back water pump outlet that is interconnected, and pump entrance is communicated in the wastewater disposal basin bottom.
The utility model further improvement project is, on the pipeline between water pump and the wastewater disposal basin, and on the filler pipe road between water pump and pulper, the shower nozzle, spray piping, is respectively equipped with switch valve.
The utility model compared with prior art has following obvious advantage:
One, used device is few, can effectively control discharged waste water, reduces cost.
Two, this cover closed cycle system plain boiled water utilization rate is high, and operating cost is low, has thoroughly solved evaporating, emitting, dripping or leaking of liquid or gas
Phenomenon has effectively reduced the water consumption of ton paper, and a ton paper water is reduced to the 5-7 ton, occupies leading domestic status.
Three, reduce the processing pressure and the processing cost of sewage, the conserve water resource.
Description of drawings
Fig. 1 is the utility model sketch map.
The specific embodiment
As shown in Figure 1, the utility model comprises wastewater disposal basin 1, pulper 2, polydisc thickener 3.Still as shown in Figure 1, be provided with litter decoration fermentation vat 4 on wastewater disposal basin 1 side, be communicated with filler pipe road 5 between said wastewater disposal basin and the pulper 2, and be communicated with spray piping 6 between the fermentation vat 4, the shower nozzle 7 of said spray piping 6 is arranged at litter decoration fermentation vat 4 tops.Still as shown in Figure 1, the shower nozzle 7 of spray piping 6 is a circular straighttube, and the one of which end is communicated with spray piping 6, and the other end is a blind pipe; Said shower nozzle 7 is provided with some spray orifices (spray orifice is arranged on the tube wall of circular straighttube axis with upper/lower positions, and diagram is not provided).Said shower nozzle 7 is arranged on the support 8.
Still as shown in Figure 1, be provided with waste water between said polydisc thickener 3 and the wastewater disposal basin and flow out pipeline 9.Said filler pipe road 5, spray piping 6 one ends are communicated in pulper 2, shower nozzle 7 respectively, water pump 10 outlets after the other end is interconnected, and water pump 10 inlets are communicated in wastewater disposal basin 1 bottom.On the connecting pipe 11 between water pump 10 and the wastewater disposal basin 1, and on the filler pipe road 5 between water pump 10 and pulper 2, the shower nozzle 7, spray piping 6, be respectively equipped with switch valve 12.
