Description
Technical field
The utility model belongs to paper mill sludge processing technology field, is specifically related to a kind of paper mill sludge recycling system.
Background technology
Along with the development of papermaking industry and the construction of Pollution treatment installation, the mud that paper waste produces after treatment facility process becomes new source of pollution.These mud only have part to obtain outside comprehensive utilization, and all the other are sanitary landfill process, need a large amount of landfill soils every year, both waste land resources, and also can produce secondary pollution.Cause imponderable loss to national economy, be also a kind of huge waste to resource simultaneously.Paper mill sludge belongs to biosolids waste, and it is both containing plant nutrients such as a large amount of cellulose families organic matter and nitrogen, phosphorus, potassium, again containing micro heavy and pathogenic bacteria.According to this characteristic, paper mill sludge can be become Agricultural Fertilizer and paper making raw material is recycled, can considerable economic benefit be brought to enterprise and produce good environmental benefit like this.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of paper mill sludge recycling system.This system cost is low, reasonably utilizes plain boiled water, arrives the object of energy-conserving and environment-protective.
The technical solution of the utility model is achieved in that a kind of paper mill sludge recycling system comprises sludge sump, sludge pump, vibratory screening apparatus, mixing pit, storage basin, dehydration equipment, fiber recovery machine and the air floatation machine connected successively; Described mixing pit is also connected with compound pump and medicament pond in turn, is also provided with stirrer in described storage basin; Described dehydration equipment is provided with filtered solid outlet, and fiber recovery machine is provided with discharge port, and air floatation machine is provided with clear water output.
Preferably, described dehydration equipment is centrifuge or pressure filter.
Preferably, also recycle pump is provided with in described mixing pit.
The utility model solves the defect existed in background technology, has following beneficial effect:
The paper mill sludge recycling system that the utility model provides, paper mill sludge, through chemical treatment and processed, finally becomes mud cake and discharges.Mud cake can be used as Agricultural Fertilizer and uses, and such as air-dryly directly to use as soil improvement agent afterwards; After mud cake compost as soil improvement agent use or mud cake compost secondary processing becomes compoiste fertilizer to use.The fiber impurity obtained through fiber recovery machine also can be used for the slurry of the production carrying out paper; The clear water obtained by air floatation machine process can be discharged through clear water output, carries out paper industry utilization, saves production cost.This both can solve waste problems, can create considerable economic benefit again, energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 is the structural representation of paper mill sludge recycling system;
In figure: 1-sludge sump, 2-medicament pond, 3-sludge pump, 4-vibratory screening apparatus, 5-compound pump, 6-mixing pit, 7-storage basin, 8-stirrer, 9-dehydration equipment, 10-filtered solid outlet, 11-fiber recovery machine, 12-air floatation machine, 13-clear water output, 14-discharge port.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of paper mill sludge recycling system as shown in Figure 1, this paper mill sludge recycling system comprises the sludge sump 1, sludge pump 3, vibratory screening apparatus 4, mixing pit 6, storage basin 7, dehydration equipment 9, fiber recovery machine 11 and the air floatation machine 12 that connect successively; Mixing pit 6 is also connected with compound pump 5 and medicament pond 2 in turn, is also provided with stirrer 8 in storage basin 7; Dehydration equipment 9 is provided with filtered solid outlet 10, and fiber recovery machine 11 is provided with discharge port 14, and air floatation machine 12 is provided with clear water output 13.Dehydration equipment 9 is centrifuge or pressure filter.Also recycle pump is provided with in mixing pit 6.
Working process of the present utility model is: first paper mill sludge focuses on sludge sump 1, to be sent into that vibratory screening apparatus 4 carries out screening, desanding enters in mixing pit 6 from sludge sump 1 by sludge pump 3; Medicament simultaneously in medicament pond 2 pumps in mixing pit 6 by compound pump 5, fully mixes, carry out disinfection and remove the metal ion in mud to mud with mud wherein.The interior recycle pump of mixing pit 6 circulates.Then mud sends into storage basin 7 by sludge pump 3, in storage basin 7, by stirrer 8, mud is mixed.Then enter dehydration equipment 9 and carry out processed.The paper pulp that mud workshop is discharged has very high fibre content, adds appropriate poly-propionyl enamine and just can reach good dehydrating effect before entering belt filter press.In dehydration equipment 9, after concentrated mud fully mixes with certain density flocculation agent, the cotton-shaped agglomerate that minute solid particles coacervation in mud becomes volume larger, isolate free water simultaneously, mud after flocculation is transported on the strainer of the concentrated gravity dehydration in dehydration equipment 9, free water is separated under gravity, form the mud of stagnant condition, then be clamped between upper and lower two guipures, through wedge shape precompressed zone, the ascending squeeze in low pressure area and high pressure area, under shear action, progressively extrude mud, to reach maximum mud, water is separated, finally form mud cake to be discharged by filtered solid outlet 10.Mud cake can be used as Agricultural Fertilizer and uses, and such as air-dryly directly to use as soil improvement agent afterwards; After mud cake compost as soil improvement agent use or mud cake compost secondary processing becomes compoiste fertilizer to use.Considerable economic benefit can be produced.The supernatant liquor of dehydration equipment 9 is back to the small suspended matter (as paper pulp fiber etc.) that fiber recovery machine 11 removes in supernatant liquor and separates to greatest extent, realize solid, liquid two-phase to be separated, clearance can reach more than 96%, these paper pulp fibers are discharged by discharge port 14, use as slip house making beating.The inflow air floatation machine 12 of last separated supernatant liquor processes, and removes fiber fines and other soluble substances further, makes water become clear.Clear water is discharged by clear water output 13, can be used to commercial paper production and application, as washed the water such as net, making beating.This both can solve waste problems, can create considerable economic benefit again, energy-conserving and environment-protective.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
