Description
Technical field
The invention belongs to technical field of waste treatment, and in particular to a kind of Combustion Properties of Municipal Solid Waste gasification process.
Background technology
The processing mode of current municipal refuse mainly has landfill, compost, burning and cracking.Landfill disposal need to take a large amount of soil
Ground.Meanwhile, oxious component also can cause severe contamination to air, soil and water source in rubbish, not only break up ecological environment, also tight
It is detrimental to health again；Compost treatment will be sorted to rubbish, be classified, it is desirable to which the organic content of rubbish is higher, and compost
Processing is unable to minimizing, still needs to take a large amount of soils；The essence of burning is in high temperature and the sufficient condition of oxygen supply by organic waste
Under be oxidized to gaseous inert gas thing and inorganic noncombustibles, to form stable solid residue, its advantage is rapid volume reduction ability
Thoroughly high temperature is innoxious, and floor space less, and has energy recovery but due to the presence of oxygen, but when burning in rubbish
Chlorinated organics will unavoidably produce the violent in toxicity bioxin for being difficult to decompose, the bottleneck as restriction waste incineration application.
House refuse cracking is technology newly developed in recent years, and operation is to be first using intelligence sorting by house refuse
System, sub-elected metal, glass, building materials, plastics etc. can the raw material that utilizes of direct circulation, the straight sourceization for realizing rubbish circulates
Utilize, then will sort remaining organic matter adds the special process production reclaimed coal of middle temperature cracking technique to carry out turning source using low temperature
Utilize.This processing mode is high to waste resources utilization rate, the generation of no bioxin, but oil product complicated component, big using difficulty,
And produce reluctant phenol water（2% or so）, msw water content is more than 50%, therefore processing time is in 4 ~ 6d or so, in addition
Large-scale production is difficult to based on bed technology.
Reluctant phenol water can be produced for house refuse cracking, and msw water content is excessive, it is necessary to dry or air-dry
Afterwards the problem of sorting, prior art needs to provide a kind of brand-new domestic waste Processing tecchnics.
The content of the invention
The invention is intended to solve the problem of house refuse cracking subsequent treatment is bothered.
A kind of Combustion Properties of Municipal Solid Waste gasification process, comprises the following steps：It is a, broken：Domestic waste is transported to
In twin shaft primary mill, coarse crushing is carried out, the rubbish size after crushing is between 2 ~ 2.5cm；
B, desiccation dehydration：Domestic waste after crushing is transported to progress microorganism dehydration in biological dewatered storehouse, it is described
Agitator and heating apparatus are provided with biological dewatered storehouse, domestic waste is stirred by agitator, while stirring
Aerobic microbial bacterial agent is added, is persistently stirred after 5 ~ 10h, stops stirring；Oxygen is continually fed into biological dewatered storehouse, is passed through
Heating apparatus by the temperature adjustment in biological dewatered storehouse to 40 ~ 55 DEG C, then 2 ~ 3d of quiescent culture；By temperature adjustment to 70 ~ 80
DEG C, and keep pressure to be 31 ~ 47kPa, start air exhauster and send into the water, carbon dioxide and methane of the generation in desiccation storehouse in the lump
Into biological adsorption deodoration system, until the moisture content of rubbish in desiccation storehouse discharges when between 25 ~ 30%, desiccation rubbish is obtained；
C, sorting：Magnetic plant, screening plant and density sorting device are passed sequentially through to the rubbish after step b processing, magnetic separation is set
Standby screening metal, screening plant and density separation screening inorganic matter and annoying compound；
D, handle respectively：Vapour is sent into thermal decomposition vaporization stove by air exhauster, the fuel gas produced after pyrolytic gasification
Into combustion chambers burn, the heat of combustion chamber is used for heating boiler；Then the steam in boiler is used to arrive steam-driven generator
Power is used to generate electricity, and the waste gas residual heat produced after burning is supplied to the heating apparatus in biological dewatered storehouse, is come out from heating apparatus
Waste gas feeding biological adsorption deodoration system in；
E, exhaust-gas treatment：Waste gas enters in biological adsorption deodoration system, using specially cultivating in biofilter on biologic packing material
Microbial film to waste gas carry out deodorization, detection free from extraneous odour after discharge.
The operation principle and beneficial effect of the present invention：
1st, a kind of Combustion Properties of Municipal Solid Waste gasification process of the invention, is first to be crushed domestic waste, broken
Particle diameter is 2 ~ 2.5cm, and too small less than 2cm or too greatly higher than 2.5cm, the treatment effect of microbial bacterial agent is difficult to ensure that.
2nd, by first being carried out to house refuse by adding microbial bacterial agent to house refuse quick desiccation dehydration after crushing,
House refuse unit weight and moisture content are reduced, house refuse mean calorie is improved, the energy reduced in incineration process of domestic garbage is damaged
Consumption, while the moisture after decomposition and other gases are extracted out, removes the moisture in rubbish, removes stink, it is ensured that house refuse is not
Moistening, not soaking to infiltrate in water, be at the state of desiccation, improve house refuse shatter value, it is ensured that follow-up sorting
Effect.
3rd, the house refuse after desiccation is decomposed is after organic matter removal, and remaining is exactly the material that cannot be decomposed, successively
Into magnetic plant, screening plant and density sorting device, desiccation rubbish is divided into three classes, inorganic matter, annoying compound and waste and old
Metal, wherein inorganic matter include brick, tile fragment and glass etc., and annoying compound includes plastics and fabric etc., handled respectively after sorting,
To improve the added value of rubbish.
4th, annoying compound obtains fuel gas by pyrolytic gasification, for power supply or heat supply, to these gas progress
Income, reduction energy consumption and processing cost can also be increased while reason.
In a word, the present invention is entered back into biological dewatered storehouse and utilized by the way that domestic waste is crushed into defined particle diameter
Aerobic resistant to elevated temperatures microbial bacterial agent is handled, and is dehydrated its desiccation, reduces moisture content, it is ensured that the drying of rubbish, and be beneficial to
The sorting process of bottom, the processing for afterwards being distinguished the rubbish after sorting burns annoying compound for generating electricity and providing
Heat, further reduces energy consumption and processing cost, this is simple for process, can handle on a large scale, and bioxin gas is not produced,
Floor space is also little, moreover it is possible to increases the added value of domestic waste, is worthy of popularization.
Further, the bread worm of described microbial bacterial agent is between 30 ~ 60 DEG C, biological decomposition temperature is 60 ~ 85
Between DEG C.The purpose for screening these microbial bacterial agents is, because garbage decomposition can produce substantial amounts of heat, to cause house refuse
Temperature uprise, in order to not influence discomposing effect, resistant to elevated temperatures microbial bacterial agent can only be screened.Simultaneously at such a temperature also can be true
Protect the moisture decomposed and become gaseous state discharge.
Further, microbial bacterial agent includes bacillus subtilis, bacillus licheniformis, Bacillus macerans, Richter scale wood
Mould, series bacillus, koning trichoderma, white mould bacterium, nitrogen-fixing bacteria, phosphate solubilizing bacteria and potassium solubilizing bacteria.
Further, multilayer storing plate is provided with biological dewatered storehouse, the thickness of every layer of storing plate is 10 ~ 20cm, storing plate
On be equipped with some air-vents.It is in the case where not implementing stirring to set multi-layer porous purpose, it is ensured that every layer of life rubbish
Rubbish can be contacted fully with oxygen, improve breeding potential and discomposing effect.
