Therefore, composting There are also many problems in the product market; the fatal defect of incineration of waste is high temperature (about 850 ° C), SOx, NOx, HCl, HF, dust and heavy metals in residues in the incineration flue gas products will cause serious secondary Pollution, especially the highly toxic dioxins, can be produced in large quantities.
在土地资源日益稀缺的现状下，原生垃圾“零填埋”将逐步成为发展趋势。垃圾焚烧将是实现此趋势的重要发展方向，焚烧需要解决的核心技术是二噁英及烟气排放问题。Under the current situation of increasingly scarce land resources, "zero landfill" of primary waste will gradually become a development trend. Waste incineration will be an important development direction to realize this trend. The core technology to be solved in incineration is the problem of dioxin and flue gas emission.

垃圾的热解和焚烧是两个完全不同的过程。焚烧是一个放热过程，而热解是吸热过程。焚烧的主要产物是二氧化碳和水，而热解的主要产物是可燃的低分子化合物，如气态的氢气、甲烷、一氧化碳等有机物，固态的主要是焦炭和炭黑。Pyrolysis and incineration of waste are two completely different processes. Incineration is an exothermic process whereas pyrolysis is an endothermic process.

本发明的可有机垃圾低温磁化裂解设备，炉体1内的温度优选通过电加热和鼓风机风量来自动调整，如温度过高则调频鼓风机减少风量或减少电加热功率；如温度过低则调频鼓风机增大风量或增加电加热功率。In the low-temperature magnetization cracking equipment for organic waste of the present invention, the temperature in the furnace body 1 is preferably automatically adjusted by electric heating and the air volume of the blower. If the temperature is too high, the frequency-modulated blower will reduce the air volume or reduce the electric heating power; Increase the air volume or increase the electric heating power.
炉体1内的负压优选由引风机来自动调整，如炉体1内的负压低于设定值则调频引风机增大抽气量，反之则减少抽气量。The negative pressure in the furnace body 1 is preferably automatically adjusted by the induced draft fan. If the negative pressure in the furnace body 1 is lower than the set value, the frequency modulation induced draft fan increases the air extraction volume, otherwise it reduces the air extraction volume.
本发明的有机垃圾低温磁化裂解设备，其裂解产生的烟气穿过上部料层排出后，烟气中的飞灰、颗粒物、焦油等被高位料层净化；炉底与料层上部的温差大于80℃；底部固体垃圾低温燃烧热解过程中同时将上部固体垃圾干燥，落入底部后会更易于进行低温燃烧热解，提高效率。In the low-temperature magnetization cracking equipment for organic waste of the invention, after the flue gas generated by the cracking is discharged through the upper material layer, the fly ash, particulate matter, tar, etc. in the flue gas are purified by the high-level material layer; the temperature difference between the furnace bottom and the upper part of the material layer is greater than 80 ℃; the solid waste at the bottom is dried at the same time during the low-temperature combustion and pyrolysis of the solid waste, and it will be easier to carry out low-temperature combustion and pyrolysis after falling into the bottom, and the efficiency will be improved.
本发明的有机垃圾低温磁化裂解设备，其低温燃烧热解过程相当于通常燃烧过程的前期阶段即有机废弃物的挥发性气体化阶段。通过磁化空气、设置电气石10，成功实现了挥发性气体的离子化、无害化。由于无需经历火焰温度区域的剧烈化学反应就可以进行排气的处理，所以可实现无害化。由于挥发性气体离子化，在火焰燃烧或与其相当的温度区域里，即使气体曝露也不会发生普通燃烧所产生的那种含有大量的未燃烧碳化物的黑烟，不会有剧烈化学反应带来的二恶英等有害气体产生。In the low-temperature magnetization pyrolysis equipment of the organic waste of the present invention, the low-temperature combustion pyrolysis process is equivalent to the early stage of the normal combustion process, that is, the volatile gasification stage of the organic waste. By magnetizing air and setting tourmaline 10, the ionization and detoxification of volatile gas were successfully achieved. Since the exhaust gas can be treated without undergoing a violent chemical reaction in the flame temperature region, it can be detoxified. Due to the ionization of volatile gas, in the flame combustion or its equivalent temperature region, even if the gas is exposed, the black smoke containing a large amount of unburned carbides produced by ordinary combustion will not occur, and there will be no violent chemical reaction zone. Harmful gases such as dioxins are produced.
此外，本发明的有机垃圾低温磁化裂解设备机型小，安装便捷，操作方便。设备在较低温度工况下运行，与通常的高温领域的燃烧不同，运行使用寿命更长。运行时工作量少，省时省力。烟气净化彻底。In addition, the low-temperature magnetization pyrolysis equipment of the organic waste of the present invention is small in model, convenient in installation and convenient in operation. The equipment operates at a lower temperature, which is different from the usual combustion in the high temperature field, and has a longer operating life. Less workload when running, saving time and effort. The flue gas is thoroughly purified.
本发明的有机垃圾低温磁化裂解设备采用先进的低温(350℃以下)热解技术，避免了二噁英的产生，产生的炉灰不到固体垃圾重量的1％(体积量约1/300以下)，而且可以再次利用，同时独特的尾气处理技术不仅节能而且烟气排放全部达到国家及地方的最新标准。The low-temperature magnetization cracking equipment for organic wastes of the present invention adopts advanced low-temperature (below 350°C) pyrolysis technology, which avoids the generation of dioxins, and produces less than 1% of the weight of solid waste (less than 1/300 of the volume by volume). ), and can be reused, and the unique exhaust gas treatment technology not only saves energy but also meets the latest national and local standards for flue gas emissions.
