垃圾焚烧工艺流程图1.doc
本系统从垃圾投入开场到最后的出灰,整个系统全部自动程序控制。这不仅减少了操作人员,而且保障了系统平安稳定运行,到达最好的垃圾处理效果。 The system is mainly about the disposal of urban household garbage and non-toxic&harmless industrial trashthrough the advanced, reliable, mature production technology and technical equipment. After the comprehensive implementation, we can realize the purpose of changing the reduced garbage into resources in a harmless way. Also,the heat energy generated out of garbage incineration can be used in heating and power supply. The chemical equilibrium and fludic analysis of gas as well as the precise equipment selection and temperature enaction shall be executed according to garbage contents at the design stage. From primary garbage input to final ash output , the whole system is controlled by automatic program, which not only cuts the workforce, but also ensures the system safety and steady operation, thus achieving the best garbage disposal effect. 垃圾燃烧工艺流程图 Process Flow Of Grbage Incineration 城市生活垃圾剔除不可燃烧及有毒有害的废弃物后,由专用垃圾运输车辆送进厂区,驶上地磅进展称重,然后按指定路线驶向垃圾卸料平台,将垃圾卸入垃圾贮存池可贮存57天的处理量,贮存池上方设有垃圾吊,对池内垃圾进展搬运、搅拌和倒垛,以确保入炉垃圾组分均匀。 Having eliminated incombustible and noxious waste, the urban household garbage is sent to the factory by special garbage carrier. After weighed on weigh bridge, special garbage carrier is drived to garbage discharging platform, where garbage shall be unloaded into storage pool whch has the storing capacity for 5-7 days. There are two garbage cranes above storage pool for hauling ,stirring up and shifting to ensure the evenly distribution of the incinerated garbage. 垃圾燃烧系统包括从垃圾吊车接到垃圾后送至二次燃烧室进展燃烧以及垃圾燃烧炉出渣。燃烧炉的种类很多,燃烧工艺也因燃烧炉的不同而各有差异,本工程将采用国际先进的往复式机械炉排炉,它分为枯燥段、燃烧段、燃烬段。根据各段供给的空气量和调节推进的速度,适时掌控炉膛温度,提高垃圾燃烬率。 The incineration system covers the process of collecting garbage from carrier ,sending it to re-combustion space and then discharging the slag out of incinerator.there are many kinds of incinerators, Incineration technology differs by incinerators. Using the most advanced international reciprocating mechanical grate, the system is devided into drying section, combustion section and burning section. According to the air amount provided by each stage and by adjusting the velocity of clockwise pushing, furnace temperature can be controlled ,thus increasing the garbage combustion efficiency. 在整个燃烧系统中,我们将配置国内最先进、最可靠、最成熟的设备,垃圾燃烧炉的配套余热锅炉和气轮发电机组。将垃圾燃烧产生的热能通过余热锅炉产生蒸汽,然后用蒸汽供气轮机组发电、上网。 In the whole system, we will employ nationally the most advanced, most reliable and most mature equipment to produce steam by the heat generated from garbage incineration through residual heat boiler. Then the steam can be used to generate electricity through the steam electric generating set , then the electricity can be used on internet. 生活垃圾燃烧过程中产生的烟气中会有烟尘、酸性气体、重金属及二恶英等污染物。为了防止垃圾燃烧过程中对环境产生二次污染,我们将严格控制垃圾燃烧温度在850以上且停留2秒以上,以确保二恶英分解。采用投入反响助剂和消石灰的干法烟气净化处理工艺,烟气排放到达国际先进指标。 Fume produced by garbage incineration contains some contamination such as smoke dust, acidic gas , dioxin , heavy metal and so on.In order to prevent the quadric environmental pollution, the garbage incineration temperature should be strictly controlled above 850for more than 2 seconds, which hereby ensures the decomposition of dioxin.With the drying fume purification process through adding reaction auxiliary agent and lime hydrate, fume discharge thus can meet with the internationally progressive indicator. &nbps;&nbps;&nbps;&nbps;垃圾渗滤液主要产生于垃圾贮存池,是垃圾在贮存池中发酵腐烂后,由垃圾内的水分排出而造成的.它的特点是臭味重,有机污染浓度高,氨氮含量高.其含量约占垃圾量的10%左右.我们将在厂区内建立污水处理站,通过UAUB厌氧反响器、膜生化反响器,污泥处理系统处理后,达标排放,用专用管道送至城区污水处理厂。 Water inside garbage in the storage pool gives off leachate with heavy odious smell and high viscosity of organic pollution together with rich content of ammonia nitrogen,which accounting for around 10 percent of total garbage volume. Before been discharged and sent to sewage treatment plant by special duct , garbage leachate is processed by UAUB anaerobic reactor, membrane biochemical reactor and sludge disposal system at sewage treatment station which will be built in the factory垃圾燃烧后产生的炉渣占垃圾量的10%15%左右,它属于一般废弃物,它从炉中落入输送机,经过降温后送至炉渣堆放处,然后外运到指定地点,再经过加工处理后,可作铺路、制砖的辅料,进展再利用。经布袋回收下来的飞灰,占垃圾总量的3%左右,它属于危险废弃物。我们将对产生的飞灰进展无害化处理,再送填埋场进展填埋。 As a common waste, cinder is about 15 percent of garbage. After being dropped onto the conveyer from furnace, the cinder is sent to piling place after being cooled, later on transported to the designated location for the secondary machining. after which, cinder can be turned into an auxiliary material for pavage and brickmaking.The flying ash, as a hazardous waste, collected by bag filter accounting for 3 percent of garbage, then be delivered to landfill site after being treated in a harmless way. 垃圾燃烧厂的恶臭味主要来源于垃圾贮存池,我们将采用的控制与防治工艺是加强密封。一是对可能发生臭气外泄的部位都采用密封材料进展封堵;二是在卸料平台进门处设有风幕,防止垃圾车进厂时带来的臭味外泄;三是将垃圾池的臭味抽到燃烧炉膛,用燃烧的方法把臭味成分烧掉,到达脱臭效果。 Mainly from garbage storage pool, effluvium shall be controlled by reinforced seal. On one hand,caulk the pote-ntial leaking position with sealant. Secondly, set up air curtain at door of discharging platform to prevent efflluv-ium leakage when a trash truck enters. Thirdly,draw out effluvium to hearth, and realize deodorization by conflagra-ting its effluvium ingredients.
