Description
[technical field]
The invention belongs to technical field of tobacco processing.More particularly it relates to an the method for comprehensive utilization of papermaking-method reconstituted tobaccos waste liquid.
[background technology]
The production process of papermaking-method reconstituted tobaccos is the separation-regrouping process of a Nicotiana tabacum L. material, and tobacco material is separated into aqueous phase soluble substance and two parts of soluble thing by extraction and separation technology in process of production.Soluble thing obtains reconstituted tobacco intermediate product-substrate by slurrying, the processing step such as manufacture paper with pulp, and soluble substance obtains another intermediate product-coating fluid through the processing step such as refining, concentration, allotment, coating fluid backfills restructuring on substrate and obtains reconstituted tobacco.Relate to a lot of processing step owing to reconstituted tobacco produces, be a complicated process, simultaneously in order to ensure reconstituted tobacco quality, therefore inevitably cause loss in process of production, produce garbage.Along with the improvement of production technology and working hard of scientific research personnel, major part waste discharge (especially industrial water) all achieves and recycles or effectively process, but still having the recycling of two kinds of garbages is numerous reconstituted tobacco manufacturing enterprises problem encountered.One is owing to production material balance and raw material clean produced water solublity refuse, and it generally includes washes stalk water, stem extracting solution, superfluous offal extracting solution etc.；Another kind is the residue production produced in extract refining and plain boiled water circulating treatment procedure.
Current water solublity refuse generally has two kinds of processing methods: a kind of method is to be routed directly to Sewage Disposal to process；Second method is therefrom to reclaim flavor matter, and debris is sent to Sewage Disposal again and processes.Water solublity total quantity of waste material is generally relatively big, sewage plant directly process consuming time longer, difficulty is higher and investment is bigger；Flavor matter recycling then needs stronger technical force to ensure, only Ji Jia reconstituted tobacco manufacturing enterprise is capable of at present.
The solid that cannot return to production line continuation production is generally made up of silt, papermaking filler, fiber fines etc., modal processing method is burn after dehydration, due to non-combustibles such as silts, the fuel value of curable type garbage is not high, a large amount of burning may have influence on normal production, and burn the greenhouse gases discharged can further to environment simultaneously.
CN104230127A, denomination of invention " technique that biogas is prepared in reforged tobacco wastewater process " disclose and utilize Anaerobic Biotechnology that reconstituted tobacco garbage carries out the technique that anaerobic fermentation generation biogas recycles.The weak point of this technology is: the oxygen content that (1) this technique does not consider in water, for avoiding flavor matter to run off in papermaking-method reconstituted tobaccos production process, K cryogenic treatment is usually taken, therefore the loss of the dissolved oxygen in water is little, and in anaerobic reaction, this part oxygen can hinder the process of reaction to affect production efficiency；(2) for general reconstituted tobacco manufacturing enterprise hc effluent day generation amount no less than 800 tons, producing 250 days meters per year, comprehensively its anaerobic treatment effect, anaerobic reaction facility scale will be very huge, and counter investment is higher；(3) biogas is methane with the main component of natural gas, but possibly together with CO in biogas2Deng incombustible gas, its efficiency of combustion will be generally below natural gas, and (combustion of natural gas value is: 1000m3Natural gas=1.33 ton standard coal), therefore also below fire coal, biogas to be used for boiler unrealistic as replacement of fuel coal.
In view of prior art exists such technical problem, the present inventor, on the basis summing up prior art, by lot of experiments and analysis, completes the present invention finally.
