Description
Technical field
The utility model relates to a kind of organic solid-state waste reduction and disposal equipment, particularly a kind of equipment by pyrolysis way process organic solid-state refuse.
Background technology
Though organic solid waste refers to producing, the original utility value of forfeiture that produces or do not lose utility value but be abandoned or the solid-state organic article abandoned and material in life and other activities, domestic refuse common are machine solid waste the most.Kitchen waste, Plastics Packaging Wastes, waste paper and packing material etc. is had in domestic refuse; Garden waste is also organic solid waste.Present traditional way is under environment protection rules guide, according to minimizing, resource utilization, innoxious principle, strengthens the Whole Course Management produced rubbish, and actively carries out innoxiously focusing on and recycling, to prevent contaminate environment.As the technologies of garbage disposal such as sanitary landfill, burning, compost, recycling and equipment have corresponding applicable elements, suiting measures to local conditions, technical feasibility, equipment reliably, on a fairly large scale, under the principle of the comprehensive regulation and utilization, appropriateness is carried out, these long processing period, running cost is high, also easily pollutes surrounding enviroment.Garden waste is mainly to the residual branch of plant and broken leaf etc. that produce in the pruning of urban greenery plants and Renewal process, and its generation increases sharply and increases along with city ecology construction, green coverage.For a long time, the garden waste of China, mainly based on simple and easy landfill, accounts for more than 90% of whole treatment capacity.The simple and easy landfill of rubbish not only takies a large amount of soil, also add trucking costs and disposes load, and also causing the wasting of resources.For the shortcoming of simple and easy landfill, researchist is had to start garden waste to carry out recycling treatment, as formerly invented " treating process for green waste and uses thereof " application number be: 201110253821.2, disclose following a kind of technical scheme: by garden waste powder, cotton benevolence cake powder, Semen Maydis powder, wheat bran, the peat composed of rotten mosses and loam, mix by weight, add water, adjust pH, sterilizing, add streptomyces microflavus, carry out fermentative processing 5 ~ 8 days in 26 ~ 32 DEG C, tunning is as producing the treatment agent of planting.But this kind of complex process, other required material are numerous and diverse, and processing cost is high, and processes Zhou Lichang.
Pyrolysis plant, as a kind of new technical equipment, is applied to the fields such as biomass processes, greasy filth refiltered oil, coal just gradually.Pyrolytic process is under the condition of anaerobic or anoxic, thermo-cracking of being heated by organic materials, and resultant has pyrolysis gas, bio oil, charcoal etc., the equal recoverable of these resultants, and wherein pyrolysis gas is after purifying, and can be used as high-quality combustion gas; Bio oil, after refining, can be used as the oil fuel of oil engine, internal combustion turbine; Charcoal after pyrolysis also can be used as fuel, soil improvement agent, prepares activated carbon raw material etc.Because pyrolysis carries out in anaerobic or anoxia condition, be not oxidized burning, the generation of dioxin-like chemical can be stopped, therefore pyrolysis has as a kind of refuse treatment new technology and subtracts the features such as capacity is large, innoxious thoroughly, recycling is abundant, secondary pollution is little, just day by day receives publicity and payes attention to.The requirement of pyrolysis to raw material is that moisture content is low, and viscosity is low, calorific value is high.To domestic refuse, particularly kitchen waste, its water ratio is higher, the rear viscosity of pulverizing is comparatively large, and individual curing is not suitable for pyrolysis; After adding garden waste mixing, water ratio and the viscosity of domestic refuse can be reduced, thus be applicable to pyrolysis, and its calorific value can be improved, strengthen to recycle being worth.
Based on the feature of pyrolysis, each state has all developed some technology and equipments, application purpose and place different, wherein a part obtains small-scale application, be more in research and demonstration phase.Outer pattern of fever, interior pattern of fever, self-heating type etc. are had by type of heating; Tubular reactor, fluid bed furnace, multi-layer rake type stove and rotary kiln etc. are had by raw material transport flowing mode.
Autothermal retort stove is destructive distillation while, in gas retort, pass into a certain amount of air, and make the pyrolysis of part destructive distillation material combusting, therefore raw material availability is lower, only adopts in small-scale production.
Fluid bed furnace is that one utilizes gas or liquid to make solid particulate be in suspended motion state by particulate solid layer, the Reaktionsofen of go forward side by side promoting the circulation of qi solid state reaction process or liquid and solid phase reaction process.The advantage of fluidized-bed reactor is: the continuous input and output that 1. can realize solid materials; 2. the motion of fluid and particle makes fluidized-bed layer have good heat transfer property, and bed internal temperature is even, and is easy to control, and is specially adapted to strong exothermal reaction; But then, because back-mixing is serious, certain influence can be brought to the selectivity of the efficiency of reactor and reaction; The existence of adding gas-solid fluidized bed middle bubble makes gas-solid contact be deteriorated, and causes gas reaction to obtain not exclusively.Therefore, the very high reaction of requirement per pass conversion should not be usually used for.In addition, the dust in the wearing and tearing of solid particulate and air-flow is carried secretly, also makes the application of fluidized-bed be subject to a definite limitation.
Multi-layer rake type Reaktionsofen is combined respectively from top to down by multilayer siege, its body skin is generally steel cylinder shape, inwall builds fire-brick lining, central authorities' firebrick arch is built and is formed several layers of siege, mostly be 4 ~ 12 layers, the high temperaturesteel axle of crowngear driven rotary is housed at the center of stove, can rotate by 0.5 ~ 2rpm rotating speed, rake arms is equipped with in the both sides of axle, under arm, some rake teeths are housed, axle and arm are all double-layer structurals, blowing air cools, cooling air is crossed in each arm from pipe advection in axle and is managed, the loop of axle is returned to from pipe, become warm air (200 ~ 260 DEG C).Reaction mass is supplied by furnace roof, on the bed board of the first layer stove, because the stirring action of rake arms and rake teeth shifts to center, fall second layer furnace bed board from the perforate of central part, the direction of second layer stirrer gear is contrary with the first layer, pushes material to outer, and fall on third layer bed board, the like until floor grate bed board, finally draw off from bottom discharge device, obtain reactor product.Therefore such stove design, manufacture, technique and process control requirements are high, and the cycle is long, and different material needs according to its atmosphere characteristic requirements, makes to measure.
In a word, interior pattern of fever, self-heating type Reaktionsofen are all burning Reaktionsofens, and its smoke eliminator produced after burning requires higher, and have the shortcoming of contaminate environment, and raw material availability is lower, their application is subject to certain limitation.And the retort stove of outer pattern of fever, fluid bed furnace, multi-layer rake type stove, because its design, manufacture, technique and process control requirements are high, investment is large, the cycle is long, and their application is also subject to certain limitation.
Tubular reactor is one fairly simple in pyrolysis installation.Reactor is the pipe of certain length, and after biofuel enters pipe one end, move to the other end under spiral or the angle of rake promotion of blade, accept outside heat and pyrolytic reaction occurs in moving process, pyrolysis temperature and solid phase residence time easily control.Shortcoming is that treatment capacity is little, is not suitable for mass-producing operation.
Outer pattern of fever rotary reaction furnace is a kind of universal large-scale plant, and main body is a steel rollers, and slant setting, slowly rotates, and can arrange the accessory such as flight, scraper plate in cylinder.During work, solid materials enters from cylinder is high-end, discharges, in movement, complete pyrolytic reaction at cylinder low side.The solid materials that the revolution of cylinder makes is easy to realize fully mixing and evenly conveying, and cylinder is less demanding to material size size and shape, and treatment capacity is large, is applicable to large-scale production, therefore of many uses.But because it is direct heating, add heat smoke and treat that pyrolysis material directly contacts, there is physics contaminated, pyrolysis gas overall quality is not high, the shortcoming that the quality of pyrolysis solid product and productive rate are not high, the pyrolysis gas produced is not effective to be recycled, and overall work energy consumption is comparatively large, does not meet the requirement of energy-conserving and environment-protective.
