Description

A kind of technical process of sludge composting quick aerobic fermentation technological equipment automatically controls Method

Technical field

The present invention relates to sludge composting aerobic fermentation technical fields, are specifically a kind of sludge composting quick aerobic fermentation work The technical process autocontrol method of skill equipment.

Background technology

With the high speed development of economic construction of China and the quickening of Development of China's Urbanization, municipal sewage（Including trade effluent and Sanitary sewage）Discharge capacity drastically increase, and the sludge generated in sewage disposal process also rolls up therewith.According to relevant information Statistics ended for the end of the year 2013, and the wet mud that year generates moisture content 80% has broken through 38,000,000 tons, it is contemplated that 2020---2025 Sludge annual output will break through 60,000,000 tons.Although municipal sewage is administered, if so huge sludge quantity cannot be appropriate Reason is conducted oneself well just arbitrarily to be discharged into nature, by the serious secondary pollution including underground water source, surface water, soil and air, It is greatly endangered to urban and rural environment and people's lives health care belt.China's sludge has nearly 80% not dealt carefully at present, with Meaning disorderly fall, stack, caused by secondary pollution highlighted, cause the extensive concern of the whole society and governments at all levels.

Urban sludge treating method mainly has " sanitary landfills ", " building materials utilization ", " burning " and " land use " etc..Health Landfill has the characteristics that small investment, implementation is fast, method is simple, treatment scale is big, but this method is not fundamentally to sludge In organic matter handled and controlled, simply sludge simply carry and temporary, and occupies substantial amounts of soil money Source is a kind of not recyclable disposal options.Although sludge building material utilization can be to utilization of resources, due to currently with dirt The clay brick cost created is too high, and the brick produced is difficult to reach building standard requirement in itself, and Treatment of Sludge factory can not It bears great number cost and is restricted.Although sludge incineration processing is thorough, the volume and weight of sludge, processing can be greatly reduced Speed is fast, but sludge incineration processing cost is very expensive and the toxic and harmful gas that generates is difficult to handle after burning.Compared to it Under, to improving, sludge landfill characteristics have small investment to sludge, low energy consumption and operating cost is low after the processing of compost aerobic fermentation The features such as, and the nutriment in sludge can obtain recycling, and result of study shows that sludge composting aerobic fermentation is to work as Before most economical, most worthy the processing mode that tallies with the national condition.

Sludge composting aerobic fermentation process process is generally divided into a compost and secondary compost.Wherein a compost includes original Auxiliary material premix, compost aerobic fermentation turn over the technological operations links such as throwing, aeration oxygen supply, deodorization.And primary sludge compost aerobic fermentation Technical process plays the role of sludge reduction, innoxious and stabilization processes critical, and the factor to be controlled ratio More, such as moisture, temperature, gas permeability and ventilation oxygen supply, in factors, the variation of sludge heap temperature is to weigh sludge composting The whether normal key index of aerobic fermentation and whether normal most direct, the most sensitive index of reflection sludge body fermentation. Requirement to sludge composting heap temperature is can be summarized as under normal circumstances in a composting fermentation process, peaceful in early period temperature Surely, mid-term high temperature maintain temperature change will moderately, latter temperature decline it is slow.One time compost fermentation temperature change early period is had to Handle the relation of " fast " and " steady " well, i.e. compost fermentation plays temperature and wants fast, but warm rise cannot be too fast, steady as far as possible；Once The temperature change that compost mid-term high temperature maintains is appropriate, is preferably controlled in 55⁰C---65⁰C does not exceed 70⁰C, the excessively high meeting of temperature Make compost material ' sintering ', in short, in sludge composting aerobic fermentation process control, temperature is one most important, most direct Governing factor, in this export-oriented heap body oxygen supply in time be also promote during sludge composting aerobic fermentation indispensable one it is important Index.But less, particularly sludge is discussed on domestic at present, the external technological measure on this two key indexes are controlled The initial period of fertile aerobic fermentation（I.e. cloth terminates）, quick and stable can be found and play a kind of technological measure that is warm, supplying oxygen in time also There is no referential experience.Primary fermentation temperature environment still heats up naturally by compost heap body at present comes slowly that meet object biology numerous Condition is grown, generally requiring the time of 3 days or so could be into being rapidly heated the cycle, and which results in the entire compost fermentation cycles Lengthening.And it is being that cannot supply gas in compost temperature-rise period in the case of not having heating and control means to its temperature to be aerated Oxygen supply, supplying gas in the temperature rise period can be such that heap temperature declines rapidly, and fermentation cannot carry out.Aeration supply at present is usually in heap Temperature just starts to blow to heap Invivo oxyger-supply when reaching the high temperature upper limit of compost mid-term high temperature fermentation period, at this moment send aeration Main purpose be that heap temperature is made to cool down, and the initial period that ferments should be so by heap body material itself oxygen content and heap it is external Boundary's air provides the oxygen needed for microbial reproduction naturally into the oxygen brought into heap body, this just constrains sludge aerobic The source of a large amount of oxygens needed in fermentation process, because just not sent at fermentation initial stage into windrow containing fermentation initial temperature It is required that oxygen supply condition, and not with heap temperature gradually rises and make aeration also with the technological equipment gradually risen come Ensure, the temperature at fermentation initial stage, oxygen supply condition is caused not to possess, it by heating up and supplying oxygen naturally, can be aerobic there are sludge composting The defects of fermentation maturity cycle length, unstable product quality.Simultaneously because not supplied oxygen in time at fermentation initial stage, compost material exists Under own wt effect, material can be caused to be compacted, the gas permeability of aeration supply impacts and influence product quality to the later stage The factors of instability.

China differs greatly in the opposite developed countries of aspect that automatically control of sludge composting aerobic fermentation at present, at present The large-scale sludge composting aerobic fermentation complete set of equipments that the country introduces is there are high energy consumption, investment is big, equipment is costly and complicated, maintenance is tired It difficult, the shortcomings of operating cost is high, not fully tallies with the national condition.It is fast to find a kind of sludge composting for meeting China's fundamental realities of the country The problem of fast aerobic fermentation process equipment is current in the urgent need to address, including developing, Treatment of Sludge scale is big, processing speed Soon, highly integrated, the composting process process of environmental protection, sludge composting aerobic fermentation technology efficient, energy consumption is low and domestic external equipment Automatic collection, online data real time monitoring, data analysis, data automatic recording, data automatic archiving and the dirt of data The realization that mud compost aerobic fermentation process process automatically controls is a challenge of the pendulum in the numerous engineers and technicians in China.

Since the optimal initial temperature of sludge composting aerobic fermentation microbial reproduction generally exists（25⁰C ---35⁰C）Scope Interior, how this temperature range has just terminated just most beneficial for the growth and breeding of microorganism at compost fermentation initial stage, that is, cloth Meet this technological parameter requirement rapidly, compost is enable to rapidly enter high temperature fermentation period, shorten entire fermentation period, reduce cost It is most important.In the northern area of China, this above-mentioned technological parameter is even more important, and particularly the northern area of China winter carries out dirty Mud compost aerobic fermentation is worked continuously the importance of above-mentioned initial temperature of just more seeming, winter temperature is too low（10⁰Below C）, meeting Cause in sludge composting aerobic fermentation heap body that microorganism decomposition, degradation reaction speed are excessively slow, quality is unstable, can cause when serious Fermentation failure.

The water vapour and ammonia that China's sludge composting aerobic fermentation process generates at present（The foul smell that i.e. people are commonly called as）It cannot Processing is timely and effectively collected, roofing is caused to drip condensed water downwards, condensed water is fallen on the material in fermentation tank, to material Fermented quality has an impact, the equipment in heavy corrosion mill construction and fermentation plant.Generally use now to fermentation plant Interior air-supply, the exhausting of deodoration system cannot effectively collect water vapour and foul smell, particularly the winter of northern China, be sent into Air in fermentation plant is cold air, and temperature in workshop can be caused to decline, while the cold air being sent into is produced with fermentation process Raw hot steam crosses, and more accelerates the generation speed of condensed water, causes sludge composting aerobic fermentation environmental degradation.

The distributing mode of sludge composting aerobic fermentation is most using engineering loader cloth at present, also has a small number of using with turning over Throwing machine shares the material distributing machine of same track and belt conveyor coordinates cloth, is often occurred due to department using engineering loader cloth Machine break accidentally fermentation cell wall the phenomenon that, while engineering loader dead weight it is heavier, cloth process is scattering on ground cannot and The material of Shi Qingli is compacted, and causes later stage cleaning difficult, unfavorable to aeration ventilation, and also fermentation tank ground is had an impact, It is present with ground crackle.Although track material distributing machine can overcome the defects of engineering loader, realize that automatic distributing needs belt Conveyer coordinates, and in addition from a fermentation tank to another fermentation tank cloth, belt conveyor needs and then to shift, and is unfavorable for reality Existing automatic distributing process, while material distributing machine can not achieve self-emptying function.

Aerated conduit is to cool down for oxygen supply to be supplied oxygen and passed through into fermentation tank to the interim excessive temperature of hot fermentation, Effect is that aeration is made to be evenly distributed to inside sludge composting heap body material, maintains the aerobic shape of material inner homogeneous in fermentation tank State reduces the pressure loss, the pressure of aerating pipelines as far as possible to aeration is maintained to be evenly distributed it is necessary to be laid in aerating pipelines Loss is mainly derived from being lost along stroke pressure for pipeline, local pressure loss, pipe diameter is smaller, the longer pressure loss of length just Bigger, pipeline corner is more, and local pressure loss is bigger.Duct pressure loss accounts for 80% or so of the aerating system pressure loss, And material heap body only accounts for 20% or so to the pressure loss caused by the resistance of aeration.So reasonable Arrangement aerating pipelines are to reducing The pressure loss, to be uniformly distributed in fermentation tank aeration most important.Aerating pipelines are divided into aeration main line and aeration branch pipe road, mistake It goes to be laid with bye-pass along fermentation tank length direction always, causes that the pressure loss is big, it is uneven that pressure is aerated in pond, be partially formed and detest Aerobe fermentation generates a large amount of foul smell, sludge composting aerobic fermentation quality is impacted, unstable product quality.In addition also have more The form of a fermentation tank central gas supply causes to cause completely to stop supply during a fermentation tank failure shutdown maintenance, to whole A sludge composting aerobic fermentation impacts, while the design of aerating pipelines system does not account for mechanical redundancy yet.Air energy-storage Pressure, stability of flow when air accumulator effectively can solve to be aerated continuous supply, but at present using less.

With regard to currently available technology, for the moving vehicle that turner shifts between fermentation tank, using control manually, meat is used Whether the eye observation moving vehicle track installed above track for turner operation installed above with fermentation tank aligns, even if It is that installation travel switch control is also gross alignment, it is also necessary to which artificial accurate adjustment can just make track and displacement track on fermentation tank Road accurate alignment, it is impossible to realize and be controlled in fermentation process turner automatic shift, reduce turner operating efficiency, increase manually Cost.
