       城市生活垃圾焚烧锅炉系列 Municipal Solid Waste Incineration Boiler Series

随着经济的发展、人口的不断增多以及城市生活水平的日益提高,城市生活垃圾量也日渐增多,给环境带来的压力也越来越大。而城市垃圾还没有实行分拣,其中不可降解的成分较多,采用垃圾焚烧技术即可达到减容、减量、减少垃圾运输的目的,又能有效利用垃圾焚烧产生的热能发电,因而采用焚烧方法处理生活垃圾是一种主要方法,许多发达国家已通过实践证明,焚烧是目前处理生活垃圾的主要途径。VR彩票注册-首页锅炉设计制造的垃圾焚烧锅炉目前单台日处理城市生活垃圾量为300吨、350吨、500吨等。

垃圾焚烧炉是垃圾焚烧处理的关键设备,其主要形式简介如下:

· 回转窖形式的焚烧炉:它是通过倾斜筒体连续、缓慢地转动,使垃圾在筒中翻滚,并与热空气充分接触,完成点火,燃烧。因此回转窖式的焚烧炉多用于处理高热值的有毒、有害的医院垃圾和化工废料。

· 流化床形式的焚烧炉;垃圾在入炉前需进行分选,粉碎到≤15cm,然后送入流化床焚烧炉内燃烧,床层物料为石英砂,垃圾颗粒在炉内悬浮燃烧,燃烧过程与普通的流化床锅炉相似,因此流化床焚烧炉对垃圾颗粒的标准要求很高。同时要求进料均匀,对操作、运行及维护的要求也高。因此虽然流化床焚烧炉对垃圾的热值适应范围广,但垃圾的预处理设备的投资成本较高,而且国内尚未推广对垃圾分类收集的方式因而制约了流化床焚烧炉在国内的发展。

· 机械炉排形式的焚烧炉:这种焚烧炉因为具有对垃圾的预处理要求不高,对垃圾热值适应范围广,运行及维护简便等优点,在欧美国家得到广泛应用尤其适用于低热值、高灰分的城市生活垃圾的焚烧。我公司为美国COVANTA公司制造的垃圾炉为该种类型。该类型焚烧炉形式很多,大体分为以下几种形式。

1. 链条炉排;                      2. 滚动炉排;

3. 倾斜顺推往复炉排;        4. 倾斜逆推往复炉排等;



With the development of economies and growth of population, combined with increased urban living standards, the amount of municipal solid waste is also increasing pressure on the environment.

AS companies still look to deal with the sorting of municipal waste, including non-degradable components, volume reduction can be achieved by using incineration technology.

The use of incineration has increased over the years,as companies can reduce waste transportation costs and can effectively use the heat generated by waste incineration power. Many companies now use this process, including the Sifang factory with French company Alstom,ABB in the United States and the TAKUMA Company in japan. Co-manufacturing company Seghers in Belgium have multiple incinerations for domestic waste, using the most advanced methods. The Sifang factory waste incinerator is currently a single day municipal solid waste treatment with a capacity of 300 tons, 350 tons, 500 tons,etc.

The waste incinerator is the key to waste incineration facilities, with the main form outlined below:

· Rotary kiln incinerator form is continuous through the tilt, with the cylinder slowly rotating, so that the rolling trash barrel has full contact with the hot air to complete the fire, burning and ember in three stages. The rotary kiln type incinerator has heat values used for treatment of toxic and hazardous hospital waste and chemical waste.

· Fluidized bed incinerator in the form of garbage into the blast furnace in need of sorting, crushing to ≤15cm, and then into the fluidized bed combustion,the bed material is made of made of quartz sand, with waste particles suspended in the furnace combustion. The combustion process is similar to an ordinary fluidized bed boiler, the fluidized bed incinerator for waste particles demanding, and requires uniformity of the feed, the operation and maintenance requirements are high. Thus, while the fluidized bed incinerator for waste heat to adapt to a wide range of values, but is not yet promoting the way of garbage collection, which restricted the fluidized bed incinerator in the country development.

· Form of mechanical grate incinerator: This garbage incinerator as a pretreatment for less demanding, fit for a wide range of calorific value of waste,easy operation and maintenance, etc is widely used in Europe and America, specifically for low calorific value, high ash content, for municipal solid waste incineration, The type of incinerator is divided into the following forms:

1. Grate;  2.rolling;  3.pushed back and forth along the inclined grate;  4.to push against the push against the push reciprocating grate so inclined.

给料装置布置在垃圾焚烧炉本体和余热锅炉的前侧。包括钢制垃圾料斗、闸板门及上、下部溜槽。生活垃圾用抓斗送入钢制垃圾料斗,经闸板门及上。下部溜槽送入炉膛。为减缓垃圾对料斗的冲击和磨损,料斗内侧布置了特殊材料制作的防磨板和减震用橡胶板。料斗下布置液压驱动的闸板门,可调节入炉垃圾的给料量。溜槽上布置有料位探测器,用以监测入炉垃圾料位。下部溜槽内侧布置耐火防磨内衬。

焚烧炉本体布置在余热锅炉的下部,由钢制炉墙板组成,四周布置观测孔和检修人孔,内衬高温耐火材料,构成一个完整、密闭的燃烧空间。往复式垃圾焚烧炉排布置在焚烧炉本体的下部,由炉排框架及支架支撑固定。炉排下方布置灰斗及灰收集系统以及燃烧空气系统。垃圾由于炉排片的往复运动而向出渣口方向移动并同时得到松动,具有良好的拔火、燃烧作用。燃烬的灰渣经出渣口排入出渣机,细灰经灰斗、灰收集系统送入出渣机与灰渣一并排出。燃烧空气量及其分布均匀可调节,分为一次风、二次风送入炉膛,并在炉膛内布置轻柴油辅助油燃烧器,以保证垃圾的及时引燃。充分燃烧和燃烬,降低烟气中有害气体的排放。


The feeding device is arranged in the body and waste incinerator waste heat boiler front. Including steel trash hopper, door and gate on the lower part of the chute. Garbage into the trash hopper with a grab, the gate door and on the lower part of the chute into the furnace. To mitigate the impact of wear and tear on the hopper, the inside layout is made of a special shock-absorbing rubber plate. The hopper arrangement of the hydraulic-driven gate door, can be adjusted to the feeding amount of garbage into the furnace. Chute on the layout of a material level detector to monitor the material level waste into the furnace. The inside of the lower chute has a fire-resistant lining.

The incinerator waste heat boiler body, can be arranged in the lower part of the furnace wall composed of steel, surrounded by observation wells and the maintenance people arranged holes, lined with high temperature refractory to form a complete, sealed combustion space. Reciprocating incineration grate incinerator body arranged in the lower part of the frame and grate support bracket fixed . Arranged below the hopper grate and ash collection system and the combustion air system. Garbage because the reciprocating grate movement direction to the slag and get loose with good flames, burning effect. Ash by burning ember of the slag into the slag machine, fine ash by ash bucket, ash residue collection system into the machine together with the ash discharge. The amount of combustion air, and the distribution can be adjusted, into primary air, secondary air into the furnace, and arranged in the furnace auxiliary diesel oil burner, waste of time to ensure ignition, combustion and burning embers and reduce smoke gas emissions of harmful gases.
