下面结合实施例对本发明作进一步的描述。The present invention will be further described below in conjunction with embodiment.
固体废弃物由连接在主体炉2侧壁上端的进料装置1进入主体炉2，充满机械炉排10与主体炉2形成的空间。在主体炉2顶部中心处的螺旋搅拌器3依靠液压装置可上下移动，经过可上下移动的螺旋搅拌器3的作用形成均匀的物料层面，可使物料热解反应发生的充分而均匀。The solid waste enters the main furnace 2 from the feeding device 1 connected to the upper end of the side wall of the main furnace 2 and fills the space formed by the mechanical grate 10 and the main furnace 2 . The spiral stirrer 3 at the center of the top of the main furnace 2 can move up and down by means of a hydraulic device, and forms a uniform material layer through the action of the spiral stirrer 3 that can move up and down, so that the pyrolysis reaction of the material can occur fully and evenly.
主炉体内的中下部装有机械炉排，煤炭在机械炉排中燃烧，产生热量，使炉体内的物料预热，在温度小于250℃的时候物料的水分蒸发，在温度接近400℃的时候物料的有机物质开始热解，产生以碳氢化合物为主体的热解气体。在此过程中挥发的有机酸焦油等混合，使热解气体的可燃成分不断增加，这部分热解气体为高热值的燃气部分，通过主体炉2内的管道20进入冷凝净化器5，然后排出设备。The middle and lower part of the main furnace body is equipped with a mechanical grate. Coal is burned in the mechanical grate to generate heat, which preheats the material in the furnace body. The organic matter of the material begins to pyrolyze, producing pyrolysis gas mainly composed of hydrocarbons. During this process, the volatilized organic acid, tar, etc. are mixed to increase the combustible components of the pyrolysis gas. This part of the pyrolysis gas is a high-calorific gas part, which enters the condensation purifier 5 through the pipeline 20 in the main furnace 2, and then is discharged. equipment.
物料经过首次热解气化后形成部分物料碳，由在主炉体2内中部的螺旋推进器6向一侧推动，其中一部分推进了气体反映炉7中。螺旋推进器6与气体反应炉7相连接。气体反应炉7顶部中心处装有螺旋搅拌器8，通过液压装置螺旋搅拌器8可上下移动。在螺旋搅拌器9的作用下，使物料碳形成均匀的层面。After the first pyrolysis and gasification, the material forms part of the material carbon, which is pushed to one side by the screw propeller 6 in the middle of the main furnace body 2, and a part of it is pushed into the gas reaction furnace 7. The screw propeller 6 is connected with the gas reaction furnace 7 . A spiral agitator 8 is installed at the center of the top of the gas reaction furnace 7, and the spiral agitator 8 can move up and down through a hydraulic device. Under the action of the spiral agitator 9, the material carbon is formed into a uniform layer.
物料经过首次热解气化后形成的物料碳，一部分经螺旋推进器6向另一侧推动，进入主体炉炉体外壁的料斗9中。料斗9与机械炉排10相通，部分物料碳同时进入了机械炉排。设置在主炉体外部的空气鼓风机11通过管道将空气由底部送入主炉体，经配风室12使空气均匀穿越炉排10，使炉排10上的物料碳充分燃烧产生高温烟气，以保持机械炉排10与螺旋推进器6之间形成的高温燃烧室的温度。当不断的有物料碳进入机械炉排10，就不需要向机械炉排送煤炭来供给热解气化所需的热量了。燃烧尽的物料灰由出口13排出。Part of the material carbon formed after the first pyrolysis and gasification of the material is pushed to the other side by the screw propeller 6 and enters the hopper 9 on the outer wall of the main furnace. The hopper 9 communicates with the mechanical fire grate 10, and part of the material carbon enters the mechanical fire grate at the same time. The air blower 11 arranged outside the main furnace body sends the air from the bottom into the main furnace body through the pipe, and the air is evenly passed through the grate 10 through the air distribution chamber 12, so that the material carbon on the grate 10 is fully burned to generate high-temperature flue gas. To keep the temperature of the high-temperature combustion chamber formed between the mechanical grate 10 and the screw propeller 6 . When material carbon continuously enters the mechanical fire grate 10, there is no need to send coal to the mechanical fire grate to supply the required heat for pyrolysis and gasification. The burnt material ash is discharged from outlet 13.
气体反应炉7中下部装有供热送风加水装置，在此装置中风机通过管道与加热室连接，管道设置有阀门，风机向加热室输送空气或氧气，气量的大小由阀门控制；水泵通过管道与加热室连接，管道设置有阀门，在加热室内部的供水管道表面有均匀的孔，水泵将水通过管道送入加热室，水量的大小由阀门控制；加热室内有电热器，由加热器提供热量；在加热室内气体被加热为热风，水被蒸发为水蒸汽；加热室为密闭管道，管道表面沿径向均匀分布喷孔，喷孔三排分布共有30个，喷孔直径为4mm。经过此系统的作用，含有定量水蒸汽和定量热的热风由加热室中喷孔送出。The lower part of the gas reaction furnace 7 is equipped with a heating, air supply and water adding device. In this device, the fan is connected to the heating chamber through a pipeline. The pipeline is provided with a valve. The fan sends air or oxygen to the heating chamber. The pipe is connected with the heating chamber, and the pipe is equipped with a valve. There are uniform holes on the surface of the water supply pipe inside the heating chamber. The water pump sends the water into the heating chamber through the pipe. The water volume is controlled by the valve; Provide heat; the gas is heated into hot air in the heating chamber, and the water is evaporated into water vapor; the heating chamber is a closed pipe, and the surface of the pipe is uniformly distributed along the radial direction. There are 30 nozzle holes in three rows, and the diameter of the nozzle hole is 4mm. After the function of this system, the hot air containing quantitative water vapor and quantitative heat is sent out from the nozzle hole in the heating chamber.
物料碳充分燃烧产生的高温烟气由烟道14进入供热送风加水装置15保持燃烧室内的高温度区域，反应机理为：The high-temperature flue gas produced by the full combustion of material carbon enters the high-temperature area in the combustion chamber from the flue 14 into the heating, air-supplying and water-adding device 15, and the reaction mechanism is as follows:
燃烧尽的物料灰由出口13排出。The burnt material ash is discharged from outlet 13.
物料炭充分燃烧产生的高温烟气由烟道14进入供热送风加水系统15，其主要的成分有CO2，H2O和N2气体。900摄氏度以上的高温燃烧烟气与反应炉内物料炭的主要反应机理为：The high-temperature flue gas produced by the full combustion of material charcoal enters the heating air supply and water supply system 15 through the flue 14, and its main components are CO2, H2O and N2 gases. The main reaction mechanism of the high-temperature combustion flue gas above 900 degrees Celsius and the material carbon in the reaction furnace is:
为保证主反应炉中的反应温度，从供热送风加水系统15中提供部分氧气，使主反应炉中的物料炭产生微燃，产生的热量以保证反应过程需要的反应热，完成最后的主气化过程②和③后产生的可燃气体经气管16输送出装置。气化完成后的气体含有的燃气成分主要有CO、H2、等可燃成分，经过冷凝器和气体净化器5后排出设备，成为较低热值的燃气部分。In order to ensure the reaction temperature in the main reaction furnace, part of the oxygen is provided from the heating air supply and water addition system 15, so that the material charcoal in the main reaction furnace is slightly ignited, and the heat generated is to ensure the reaction heat required by the reaction process to complete the final reaction. The combustible gas produced after the main gasification process ② and ③ is transported out of the device through the gas pipe 16 . After the gasification is completed, the gas components mainly contain combustible components such as CO, H 2 , etc. After passing through the condenser and the gas purifier 5, it is discharged from the equipment and becomes the gas part with a lower calorific value.
送入反应炉内的O2成分已经在燃烧和继后的反应过程中消耗完毕，由于所有进料装置和输料具有密封性，因此整个热解处理过程是在无氧或缺氧的状态下进行，并且气化反应的最终温度均超过800摄氏度，这样的反应条件可杜绝或大大降低二恶英物质的发生；另外800摄氏度以上的最高处理温度可基本消灭任何病菌，并且可以分解生成的二恶英物质，达到无害化的处理效果。The O2 component sent into the reaction furnace has been consumed in the combustion and subsequent reaction process. Since all feeding devices and materials are sealed, the entire pyrolysis treatment process is in an oxygen-free or oxygen-deficient state and the final temperature of the gasification reaction exceeds 800 degrees Celsius. Such reaction conditions can eliminate or greatly reduce the occurrence of dioxin substances; in addition, the highest treatment temperature above 800 degrees Celsius can basically eliminate any germs and decompose the generated dioxins. To achieve harmless treatment effect.
反应炉产生的垃圾灰由推进器19排除。The rubbish ash that reaction furnace produces is removed by propeller 19.
为防止垃圾水分过高导致的反应物料不平衡，特设了物料平衡管17，使多余的反应气体排出至气体冷凝净化器5，冷凝为液体水和部分热解气。In order to prevent the imbalance of reaction materials caused by excessive moisture in the garbage, a material balance pipe 17 is specially set up to discharge the excess reaction gas to the gas condensation purifier 5, where it is condensed into liquid water and part of pyrolysis gas.
热解处理固体废弃物，将有5-10％部分残余物排出，排出物可进行简单筛选，回收出可再生物，如金属、玻璃等。最后剩余的残余物可进行简单填埋或作为花草养殖土，达到了减量化的处理效果。固体废弃物经由热解装置处理后，除自身消耗部分热量维持继续热解外，剩余热量以燃气的方式输出，作为清洁能源供能耗设备使用，排出5-10％的物料灰经简单筛选，除去金属、玻璃等可回收物质后，用于做花草养殖土。对热解的废弃物料成分无特殊要求，但物料中的含灰土量不得20％。由于热解过程是在缺氧或无氧条件下运行，因此可降低或消除无二恶英的产生，可实现无害化处理，同时也达到资源化和减量化的处理要求，产生的燃气还可获得一定的经济效益；如果就地处理生活垃圾，还可节省垃圾的输运费用和垃圾处理费用，杜绝输运造成的交通紧张和二次污染，产生明显的社会效益和环境效益。Pyrolysis treatment of solid waste, 5-10% of the residue will be discharged, and the discharge can be simply screened to recover renewable organisms, such as metal and glass. Finally, the remaining residue can be simply landfilled or used as soil for cultivating flowers and plants, achieving the effect of reducing the amount of treatment. After the solid waste is processed by the pyrolysis device, in addition to the heat consumed by itself to continue pyrolysis, the remaining heat is output in the form of gas, which is used as clean energy for energy-consuming equipment, and 5-10% of the material ash is discharged through simple screening. After removing metal, glass and other recyclable materials, it is used to make flower and plant cultivation soil. There is no special requirement for the composition of pyrolyzed waste materials, but the ash content in the materials shall not exceed 20%. Since the pyrolysis process operates under anaerobic or anaerobic conditions, it can reduce or eliminate the generation of dioxins, realize harmless treatment, and also meet the treatment requirements of resource utilization and reduction. The gas produced Certain economic benefits can also be obtained; if domestic waste is disposed of locally, it can also save waste transportation costs and waste treatment costs, eliminate traffic tension and secondary pollution caused by transportation, and produce obvious social and environmental benefits.
