Description
Technical field
The invention belongs to processing and the comprehensive utilization technique field of solid waste, particularly a kind of high-moisture percentage Chinese medicine slag compression-classification and resource utilization system.
Background technology
In Chinese Medicine Industry great development, Chinese medicine slag be treated as the difficult problem that traditional Chinese medicine enterprise generally runs into.How reasonably disposing and utilizing Chinese medicine slag is to realize unavoidable major issue in the modernization of Chinese medicine process.The energy of Chinese medicine slag, resource and innoxious use are the essential approach that realizes herbal pharmaceutical industry cleaner production and sustainable development.
Chinese medicine slag is the solid waste that produces in the Chinese herbal medicine process, is characterized in that moisture content is high, and perishable, smell is large.Existing processing method has burning, landfill, compost, edible fungus culturing, production of fodder, flocculant for treating waste water, pyrolytic gasification etc.Directly burn, the thermal efficiency is not high, burns cost high, and contaminated air is detrimental to health; The landfill land occupation, and can produce a large amount of percolates and foul gas, seriously polluted to surrounding environment; The Chinese medicine slag complicated component, direct compost, the security of fertilizer is difficult to guarantee.Utilize Chinese medicine slag to carry out edible fungus culturing, because dregs of a decoction complicated component may suppress mycelial growth, it is its bottleneck problem that the dregs of a decoction separate; When the dregs of a decoction are processed into feed additive, be still waiting further intensive research on its medicinal function and on the impact of animal growth; Utilize Chinese medicine slag to make flocculant for treating waste water, it is difficult point that the dregs of a decoction separate.
Have the higher dregs of a decoction of content of cellulose and the pectin class dregs of a decoction in the general Chinese medicine slag, during the Chinese medicine slag pyrolytic gasification, need screening machine to its sifting sort, carry out the anaerobism ferment after the pectin class dregs of a decoction are sorted and process; Behind the pretreating process of the fiber-like dregs of a decoction through pulverizing, mechanical dehydration, heating power oven dry, enter again gasification furnace pyrolytic gasification aerogenesis.Feed pretreatment step is long, and cellulose and the classification of the pectin class dregs of a decoction are its difficult points.
Summary of the invention
The present invention has disclosed a kind of Chinese medicine slag compression-classification and resource utilization system.Native system mainly comprises biomass garbage press apparatus, waste incineration and generating electricity equipment or biomass gasification device, two-part anaerobic ferment devices, biogas electricity generation apparatus, production fertilizer equipment.
The object of the invention is to overcome the deficiency of existing Chinese medicine slag treatment technology, adopt the biomass garbage squeezer with the Chinese medicine slag raw material at 300kgf/cm
2About pressure under, compression-classification become to be done component and wet component, does the component moisture content less than 25%, directly burning electricity generation or gasification producing steam can produce economic benefit.Do component gasification producing steam and be and do component and pass into that pyrolytic gasification obtains high-temperature fuel gas in the biomass gasifying furnace, the high-temperature fuel gas of gasification furnace output directly passes into the hot gas boiler burning and produces steam.
Wet component adopts the producing biogas by two-stage anaerobic fermentation generating, also can produce economic benefit.Natural pond liquid is concentrated to be made organic fertilizer or enters biochemical treatment of wastewater, and natural pond slag muck fertilizer is made organic solid fertilizer.
Chinese medicine slag is done the component moisture content less than 25%, density 0.5～0.8t/m behind the biomass garbage compression-classification
3, generating per ton is 500 degree or approximately 4 tons of producing steams of gasification approximately; Wet component per ton can produce 180～250m
3Biogas, ton generating is 270～375 degree approximately.
Advantage of the present invention and good effect are:
1, the present invention adopts the biomass garbage squeezer that Chinese medicine slag is carried out high-pressure compressing, Chinese medicine slag is divided into does component and wet component two large classes, can well solve the difficult problem of cellulose and pectin class dregs of a decoction classification;
2, the present invention does the component moisture content less than 25%, and burning electricity generation or gasification producing steam can produce economic benefit.Because it is very low to do the moisture content of component, thereby can be directly used in burning electricity generation or gasification producing steam, thus avoided burning or during gasification because of the too high variety of issue that causes of Chinese medicine slag raw material moisture content;
3, the wet component of the present invention adopts two-part anaerobism ferment technology, hydrolysis acidification stage and product methane phase are separated, help to keep the best living environment of each stage dominant microflora, have start fast, fermentation period is short, improve treatment effeciency, the advantages such as capacity of resisting impact load is strong, gas production is high, system run all right;
4, the wet component of the present invention is produced marsh gas power generation by the anaerobism ferment, and the natural pond slag can be made the high-quality fertilizer, and natural pond liquid can concentrate to be made organic fertilizer or enter biochemical treatment of wastewater;
5, natural pond of the present invention slag muck fertilizer obtains to be rich in the organic solid fertilizer of nutrient afterwards, and this fertilizer can satisfy fertilizer standard (NY525-2002).
This Chinese medicine slag treatment technology can really be realized Chinese medicine slag environmental protection treatment and energy recycling.
