Description
Technical field
The present invention relates to field of garbage disposal, be specifically related to one way of life garbage harmless pyrolysis treatment systems.
Background technology
Owing to there being a lot of combustible component in house refuse, if directly filled, these combustible components have just become disaster hidden-trouble, and can take a large amount of land resource.Therefore to reduce stacking, fill the destruction that soil and water body resource are caused, also for reducing disaster hidden-trouble, present usual way is to process this part combustiblerefuse by the way of directly burning, the most i.e. can reduce volume, economize the land resource, disaster hidden-trouble can be reduced again.
But owing in direct burning process, incineration firing is insufficient, many rubbish just produce a large amount of harmful gas in thermal histories, and this portion gas can be directly discharged into air after producing, and has a strong impact on atmospheric environment；Additionally, due to the oxygen content within rubbish is not enough, it is impossible to support that rubbish fully burns, easily produces the strong carcinogens such as dioxin, therefore also need to rubbish be overturn, stirs in burning process so that it is be sufficiently mixed to improve efficiency of combustion with oxygen.But this mode can produce substantial amounts of dust, and rubbish can produce stronger ascending air in combustion, bring the dust in rubbish into air, increase the weight of the pollution to atmospheric environment further.
In recent years, both at home and abroad along with increasingly stricter to incineration of waste tail gas and ash emissions standard, various countries' environmental protection circle is all at the pyrolysis incineration disposal technology exploring low stain, saving operating cost.This is that a kind of and direct-fired tradition excess air incinerator burns the diverse new technique of mechanism.Owing to most of organic compound have the feature of thermal instability, therefore, it is placed on anoxia
Under hot conditions, decomposing with under the common effect of condensation, this type organic will crack, and is converted into the gaseous state of molecular weight, liquid and solids fraction, thus reaches to process the purpose of house refuse.
The disclosure of the invention of Application No. 201310025921.9 device of a kind of pyrolysis processing rural garbage, this device is mainly made up of pyrolysis zone and combustion zone, pyrolysis zone is anaerobic environment, then Organic substance house refuse is pyrolyzed in pyrolysis zone, obtain lime-ash and flammable micro-molecular gas, then gas is in combustion zone through fully burning, finally discharges.This technical scheme can preferably realize the innoxious pyrolysis of organic matter rubbish, but the high-temperature gas after Ran Shao directly discharges, and waste heat is not used, additionally for the house refuse that moisture is more, and the house refuse that rainy day drenches, the treatment effect all cannot being satisfied with very much.
Summary of the invention
It is an object of the invention to provide one way of life garbage harmless pyrolysis treatment systems, to solve conventional pyrolysis furnaces to the higher house refuse of water content and the intractable problem of house refuse drenched rainy day, effectively make use of the waste heat of high-temperature gas after burning simultaneously.
Technical scheme: one way of life garbage harmless pyrolysis treatment systems, pond 1, feed mechanism 2, drying mechanism 5, pyrolysis oven 6, combustor 7 and air-introduced machine 9 is toppled over including rubbish, described system also includes refuse grinder 3 and condenser 8, described combustor 7 communicates with described pyrolysis oven 6, the gas produced in described combustor 7 is the most directly arranged to air, but enter described drying mechanism along the pipeline embedded in pyrolysis oven 6 and combustor 7 body of wall, described condenser 8 one end is connected with the gas outlet of drying mechanism 5, and the other end connects described air-introduced machine 9.
Further, refuse grinder 3 central shaft is provided with the crushing rod of jagged helical alignment, and described refuse grinder 3 cylinder bottom is provided with drainage screen；Refuse grinder 3 cylinder is laterally disposed, is 0-30 with horizontal plane angle, and it is high-end for toppling over one end, pond near described rubbish, and the other end of refuse grinder is low side.
Further, described drying mechanism 5 is the cylinder of band hollow interlayer, described hollow interlayer is closed, it is respectively arranged at two ends with air inlet 51 and gas outlet 52, gas outlet 52 is connected with condenser 8, hot-air does not directly contact with rubbish, but flows through hollow interlayer, heating cylinder thus rubbish is carried out heat transfer dry.
Further, described connecting gear 4 is partially or fully through the cylinder of described drying mechanism 5.
Further, the condensing tube in described condenser 8 is serpentine condenser, and described condensing tube one end connects the hollow interlayer gas outlet 52 of described drying mechanism 5, and the other end connects air-introduced machine 9.
Further, the serpentine condenser in described condenser 8 is fully immersed in below cooling water liquid level.
During work, combustion preheater pyrolysis oven 6 and combustor 7, when combustor 7 and pyrolysis oven 6 temperature reach 800 DEG C, open feed mechanism 2, connecting gear 4, refuse grinder 3 and air-introduced machine 9, house refuse is toppled over pond 1 in feed mechanism 2 is transferred into refuse grinder 3 from rubbish, and rubbish is broken, and earth in rubbish and contained portion of water are in rotating shattering process, leaching from the drainage screen of bottom, the rubbish that residue is of moderate size is sent to pyrolysis oven through connecting gear 4.
Rubbish is dried in pyrolysis oven, pyrolysis, the little molecule fuel gas produced enters combustor, fully burn, the high-temperature gas obtained continues under the traction of air-introduced machine 9, advance along the pipeline embedded in pyrolysis oven and heating wall body, drying mechanism 5 is entered by the air inlet 51 of hollow interlayer one end of drying mechanism 5, high-temperature gas flows in hollow interlayer, then flow out from gas outlet 52, play the effect of heating and thermal insulation drying mechanism, thus effectively dried the rubbish on connecting gear 4, effectively eliminate moisture.
The high-temperature gas discharged from the gas outlet 52 of air blanketing, quickly enters the serpentine condenser in condenser 8, and gas temperature is reduced to about 100 DEG C, then arranges to air, is effectively prevented the generation of dioxin.
The invention have the advantages that
1, crushing by refuse grinder, rubbish is dimensioned for pyrolysis, and removes portion of water and earth；
2, the high-temperature gas after the gas fuel burning after pyrolysis is the most directly arranged to air, but enter drying mechanism along the pipeline embedded in pyrolysis oven and heating wall body, both pyrolysis oven and combustor were played insulation effect, the most highly effective utilizing waste heat to be dried the rubbish entered before pyrolysis oven, waste heat is fully used；
3, high-temperature gas is by the serpentine condenser in condenser, and temperature is reduced rapidly, is effectively prevented the generation of dioxin.
