Description
一、技术领域 1. Technical field
本发明属于热解气化处理方法及其装置技术领域，特别是涉及垃圾处理装置。The invention belongs to the technical field of a pyrolysis gasification treatment method and a device thereof, and in particular relates to a garbage treatment device.
二、背景技术 2. Background technology
成型垃圾的气化如果采用传统的气化炉，将不可避免地使产生的燃气中含有剧毒的二恶英类物质，其合成温度为400到600摄氏度，在摄氏850度的条件下2秒中内可全部分解。在传统的气化炉中气化剂从炉底进入气化炉，气化炉由下而上为灰渣层、氧化层、还原层、干馏层、干燥层，氧化层为炉内温度最高处，其次为还原层，再次为干馏层，干燥层温度最低。在气化炉中二恶英类物质产生于干馏层中，干馏层的温度为350～800摄氏度，由于二恶英合成后只经过温度低于摄氏350度的干燥层后即离开气化炉，在气化炉中不可能发生分解，因此煤气中将含有大量剧毒的二恶英类物质，所以传统的气化炉不能用于成型垃圾的气化。If a traditional gasification furnace is used for the gasification of molded waste, the gas produced will inevitably contain highly toxic dioxins. The inside can be completely decomposed. In the traditional gasification furnace, the gasification agent enters the gasification furnace from the bottom of the furnace. The gasification furnace is composed of ash layer, oxide layer, reduction layer, dry distillation layer, and drying layer from bottom to top. The oxide layer is the highest temperature in the furnace. , followed by the reducing layer, followed by the dry distillation layer, and the drying layer has the lowest temperature. In the gasification furnace, dioxins are produced in the dry distillation layer, and the temperature of the dry distillation layer is 350-800 degrees Celsius. After the dioxin is synthesized, it only passes through the dry layer with a temperature lower than 350 degrees Celsius before leaving the gasifier. It is impossible to decompose in the gasification furnace, so the gas will contain a large amount of highly toxic dioxins, so the traditional gasification furnace cannot be used for the gasification of molded waste.
与本发明相关的背景文件为垃圾再生燃气发生炉(专利申请号00124777.8)，其在背景文件中公开的“垃圾反火气化炉”的目的是气化成型垃圾，并在气化成型垃圾的过程中将成型垃圾在干馏阶段产生的二恶英类剧毒物质有效地分解。其结构是，气化炉的炉体内，除底部有一可旋转的塔形炉栅外是中空的，气化剂的进口在炉体上部，燃气出口在炉体底部。工作时，成型垃圾原料从炉顶加入，在塔形炉栅的承托下，形成物料床层。气化剂从气化炉的顶部进入气化炉，自上而下依次通过干燥层、干馏层、氧化层、还原层、灰渣层，产生的燃气通过塔形炉栅的间隙后，经设置在塔形炉栅下的燃气出口输出。在干馏层中合成的二恶英类物质离开气化炉前将通过温度高达1100～1300摄氏度的氧化层和温度为900～1100摄氏度的还原层，所以当燃气离开气化炉时，其中的二恶英类物质已经完全分解，因此可以制取洁净的燃气。The background document relevant to the present invention is the garbage regeneration gas generator (patent application number 00124777.8), and the purpose of the "garbage backfire gasifier" disclosed in the background document is to gasify and form garbage, and in the process of gasifying and forming garbage It effectively decomposes dioxin-like highly toxic substances produced in the dry distillation stage of molded waste. Its structure is that the furnace body of the gasifier is hollow except for a rotatable tower-shaped grate at the bottom, the inlet of the gasification agent is at the upper part of the furnace body, and the gas outlet is at the bottom of the furnace body. When working, the shaped waste raw materials are added from the top of the furnace, and under the support of the tower-shaped grate, a material bed is formed. The gasification agent enters the gasification furnace from the top of the gasification furnace, and passes through the drying layer, carbonization layer, oxidation layer, reduction layer, and ash layer in sequence from top to bottom. Gas outlet output under tower grate. The dioxins synthesized in the carbonization layer will pass through the oxidation layer with a temperature of 1100-1300 degrees Celsius and the reduction layer with a temperature of 900-1100 degrees Celsius before leaving the gasifier, so when the gas leaves the gasifier, the dioxins The oxins have been completely decomposed, so clean gas can be produced.
反火气化炉有以下两个不足之处是不可避免的：一为气化效率较低，由于反火气化炉的氧化层在还原层之上，气化剂首先进入氧化层，在氧化层中发生C+O2＝CO2的氧化反应，并放出大量的热量，供下部还原反应之用；在还原层中主要发生CO2+C＝CO的还原反应以及H2O+C＝CO+H2的水煤气反应。当还原层下部的温度随着反应的进行而下降到反应停止时，物料层成为灰渣层。由于还原反应和水煤气反应都必须在碳过剩的环境中进行，所以还原层中必须保持较高的碳含量，相应的转入灰渣层的物料中碳含量较高，一般将超过5％，所以反火气化的气化效率较低。二为气化强度较低。在反火气化炉中为了保证气化的连续、稳定的进行，气化剂的通入速度将受到严格的控制，气化剂的通入速度增加将使炉内氧化层厚度增加，并使氧化层向下移动，造成还原层的减薄和下移，使还原反应失去必要的时间，导致还原反应不充分，燃气中CO2含量增加，CO和H2的含量减少，燃气质量下降，严重时还将由于燃气中氧含量过高而发生事故。氧化层的下降还将使灰渣层温度上升，对炉栅的运行和寿命造成严重的危害，所以反火气化只能在较小的气化强度下工作。The reverse fire gasifier has the following two disadvantages, which are inevitable: one is that the gasification efficiency is low, because the oxide layer of the reverse fire gasifier is above the reduction layer, the gasification agent first enters the oxide layer, and in the oxide layer The oxidation reaction of C+O 2 =CO 2 occurs, and a large amount of heat is released for the reduction reaction of the lower part; in the reduction layer, the reduction reaction of CO 2 +C=CO and H 2 O+C=CO+H mainly occur 2 water gas reaction. When the temperature of the lower part of the reduction layer drops to the point where the reaction stops, the material layer becomes the ash layer. Since both the reduction reaction and the water-gas reaction must be carried out in an environment with excess carbon, a high carbon content must be maintained in the reduction layer, and the corresponding carbon content in the material transferred to the ash layer is relatively high, generally exceeding 5%, so The gasification efficiency of backfire gasification is low. Second, the gasification intensity is low. In order to ensure the continuous and stable gasification in the reverse fire gasification furnace, the feeding speed of the gasification agent will be strictly controlled. The increase of the feeding speed of the gasifying agent will increase the thickness of the oxide layer in the furnace and make the oxidation The layer moves downward, resulting in the thinning and downward movement of the reduction layer, which makes the reduction reaction lose the necessary time, resulting in insufficient reduction reaction, the increase of CO2 content in the gas, the decrease of CO and H2 content, and the decline of gas quality. In severe cases There will also be accidents due to excessive oxygen content in the gas. The decline of the oxide layer will also increase the temperature of the ash layer, which will cause serious harm to the operation and life of the grate, so the reverse fire gasification can only work under a small gasification intensity.
三、发明内容 3. Contents of the invention
本发明需要解决的技术问题是：提供一种垃圾处理方法及其装置，它不仅可以将燃气中的二恶英类物质有效地在气化过程中分解，而且还可以在较大的气化强度下以较高的气化效率稳定地运行。The technical problem to be solved by the present invention is to provide a garbage treatment method and its device, which can not only effectively decompose the dioxins in the gas in the gasification process, but also can It can run stably with high gasification efficiency.
本发明的技术解决方案是：一种垃圾处理装置，包括料斗、炉体、炉栅以及设置在炉体内的燃气通道；所述的燃气通道的一端为使炉体内可燃气进入的燃气入口，另一端为使可燃气向炉外排出的燃气出口，其特征在于：The technical solution of the present invention is: a garbage disposal device, including a hopper, a furnace body, a grate, and a gas passage arranged in the furnace body; one end of the gas passage is a gas inlet for allowing combustible gas to enter the furnace body, One end is a gas outlet for discharging combustible gas to the outside of the furnace, which is characterized in that:
--所述炉体内设有隔墙，隔墙的底部与炉栅之间是中空的并由此形成炉体自身的空腔；--The furnace body is provided with a partition wall, and the bottom of the partition wall and the grate are hollow to form the cavity of the furnace body itself;
--所述炉体自身的空腔的上部为封闭状态，所述的燃气出口与炉体自身的空腔不直接相通，而只与燃气通道相连通；--The upper part of the cavity of the furnace body itself is in a closed state, and the gas outlet is not directly communicated with the cavity of the furnace body itself, but only communicated with the gas channel;
--所述燃气通道设在所述隔墙内，以使燃气全部从其中通过，所述的燃气通道包括垂直燃气通道和水平燃气通道，所述的垂直燃气通道上端与水平燃气通道相通，所述水平燃气通道的端部即为燃气出口；--The gas channel is set in the partition wall so that all the gas passes through it, the gas channel includes a vertical gas channel and a horizontal gas channel, the upper end of the vertical gas channel communicates with the horizontal gas channel, the The end of the horizontal gas channel is the gas outlet;
--所述燃气入口位于炉体的下部且在料层的还原层内，并与多条所述垂直燃气通道的底部相通；--The gas inlet is located in the lower part of the furnace body and in the reduction layer of the material layer, and communicates with the bottom of the plurality of vertical gas channels;
--所述垂直燃气通道位于炉体的下部，以使气化剂自下而上通过所述炉栅进入料层的灰渣层。--The vertical gas channel is located at the lower part of the furnace body, so that the gasification agent can pass through the grate from bottom to top and enter the ash layer of the material layer.
本发明与反火气化比较具有以下优点，第一，氧化层中物料的碳含量从上到下逐步降低，而氧化层所接触的气化剂中的氧含量则是从上到下逐步升高。这就使氧化层物料在碳含量较低时接触到氧含量很高的新鲜的氧化剂，从而保证氧化反应进行得较为彻底，因此灰渣中的碳含量比反火气化法大大减低，使气化效率大大提高。第二，可以在较大的气化强度下进行气化，当气化剂通入量加大后，相应使塔形炉栅的转速加快，提高灰渣排出速度，即可保证氧化层不上移，即使灰渣的数量增加，由于气化剂的流速增大，使之与灰渣之间的热交换加剧，因此灰渣的排出温度不会上升，故不会对塔形炉栅造成危害。所以，中置式成型垃圾气化炉的气化强度将比反火气化炉提高一倍以上。本发明所涉及的成型垃圾气化炉由于还原层的温度高达900～1000摄氏度，干馏时产生的剧毒二恶英类物质在此温度下将完全分解，输出的燃气中将不含有毒成分。不仅可以将燃气中的二恶英有效地在气化过程中分解，而且可以在较大的气化强度下以较高的气化效率稳定地运行。Compared with backfire gasification, the present invention has the following advantages. First, the carbon content of the material in the oxide layer gradually decreases from top to bottom, while the oxygen content in the gasification agent that the oxide layer contacts gradually increases from top to bottom. . This makes the oxide layer material contact with fresh oxidant with high oxygen content when the carbon content is low, so as to ensure that the oxidation reaction is carried out more thoroughly. Efficiency is greatly improved. Second, gasification can be carried out at a higher gasification intensity. When the amount of gasification agent is increased, the rotation speed of the tower grate is correspondingly accelerated, and the discharge speed of ash and slag is increased to ensure that the oxide layer does not build up. Even if the amount of ash increases, the heat exchange between the gasification agent and the ash will intensify due to the increase of the flow rate of the gasification agent, so the discharge temperature of the ash will not rise, so it will not cause harm to the tower grate . Therefore, the gasification intensity of the mid-mounted shaped waste gasifier will be more than double that of the reverse fire gasifier. Since the temperature of the reducing layer of the molded garbage gasification furnace involved in the present invention is as high as 900-1000 degrees Celsius, highly toxic dioxins produced during dry distillation will be completely decomposed at this temperature, and the output gas will not contain toxic components. Not only can the dioxin in the fuel gas be effectively decomposed in the gasification process, but also it can operate stably with a higher gasification efficiency under a larger gasification intensity.

气化剂通过灰渣层向上进入氧化层，由氧化层产生的二氧化碳以及水蒸气向上进入还原层后，与还原层中的碳发生还原反应，生成一氧化碳和氢气，并从若干个燃气进口12，通过与燃气进口12数量相同、也可以不同的支燃气道17，在环形总燃气道18汇合后，由燃气出口管16向外输送。The gasification agent enters the oxidation layer upwards through the ash layer, and the carbon dioxide and water vapor produced by the oxidation layer enter the reduction layer upwards, and then undergo a reduction reaction with the carbon in the reduction layer to generate carbon monoxide and hydrogen, which are fed from
物料层中的干馏层位于燃气进口管上部，干馏层中产生的干馏气中含有剧毒的二恶英类物质，由于炉体6的上部没有燃气出口，所以，随着干馏气的增加，炉体6上部的压力也逐渐增大，这将迫使干馏气向下，即向温度超过900度的还原层运动，此时干馏气中的有毒物质将在高温下全部裂解。经过高温裂解的燃气分别进入燃气进口12，燃气进口12位于固体物料床的还原层，通过支燃气道17，在环形总燃气道18汇合后，由燃气出口管16向输出。The dry distillation layer in the material layer is located at the upper part of the gas inlet pipe, and the dry distillation gas produced in the dry distillation layer contains highly toxic dioxins. Since there is no gas outlet in the upper part of the
