  控制温度:温度是热解气化过程中的关键控制参数。合理控制炉膛温度,不同温度范围会影响产品产量、成分比例及反应速率。一般来说,要保证垃圾中的有机物能够充分裂解并转化为可燃气体,但温度并非越高越好,过高会增加设备运行成本、加剧设备腐蚀和导致垃圾灰渣结焦等问题,需找到合适的温度范围以提高热解气化炉的效率。

  Temperature control: Temperature is a key control parameter in the pyrolysis gasification process. Reasonable control of furnace temperature, different temperature ranges will affect product yield, composition ratio, and reaction rate. Generally speaking, it is necessary to ensure that the organic matter in the garbage can be fully decomposed and converted into combustible gases. However, the higher the temperature, the better. Excessive temperature can increase equipment operating costs, exacerbate equipment corrosion, and cause problems such as garbage ash coking. It is necessary to find a suitable temperature range to improve the efficiency of the pyrolysis gasification furnace.

  调节加热速率:加热速率对反应产物的成分比例有影响。过快或过慢的加热速率都不理想,在实际操作中要找到最佳的加热速率范围,既能保证气体产量,又能尽量减少水分和有机物液体的损失,从而提升能源利用效率。

  Adjust heating rate: The heating rate has an impact on the composition ratio of the reaction products. Heating rates that are too fast or too slow are not ideal. In practical operation, it is necessary to find the optimal heating rate range that can ensure gas production while minimizing the loss of moisture and organic liquids, thereby improving energy utilization efficiency.

  把控反应时间:反应时间与物料尺寸、分子结构特性、反应器内的温度水平及热解方式等因素有关。物料尺寸越小、反应温度越高,反应时间可能越短,但要注意在实际操作中需找到平衡点,保证废料在反应器中有足够的保温时间以充分利用原料中的有机质并脱出挥发分,同时避免保温时间过长导致处理量减少或过短造成热解不完整的情况,以此提高热解效率。

  Control reaction time: The reaction time is related to factors such as material size, molecular structure characteristics, temperature level inside the reactor, and pyrolysis method. The smaller the material size and the higher the reaction temperature, the shorter the reaction time may be. However, it is important to find an equilibrium point in practical operation to ensure that the waste has sufficient insulation time in the reactor to fully utilize the organic matter in the raw materials and remove volatile components. At the same time, avoiding situations where the insulation time is too long, resulting in a decrease in processing capacity, or too short, leading to incomplete pyrolysis, in order to improve pyrolysis efficiency.

  合理控制进氧量

  Reasonably control the oxygen intake

  热解气化炉可控制进氧量比例(全过程缺氧)将垃圾中的有害物处理成可燃气体,把固体不完全热解过程转变为气体完全热解过程,大大减少固体颗粒物的排放量。在热解气体自燃时,温度达到一定程度助燃装置自动停止,可降低运行成本,实现垃圾热能的资源化利用,减少CO?总排放量等,通过对进氧量的合理控制来提升能源利用效率和处理效果。

  The pyrolysis gasifier can control the oxygen intake ratio (oxygen deficiency throughout the entire process) to process harmful substances in garbage into combustible gases, transforming the incomplete solid pyrolysis process into a complete gas pyrolysis process, greatly reducing the emission of solid particles. When the pyrolysis gas self ignites, the combustion assisting device automatically stops when the temperature reaches a certain level, which can reduce operating costs, realize the resource utilization of waste heat energy, reduce the total emissions of CO, and improve energy utilization efficiency and treatment effectiveness through reasonable control of oxygen intake.

  高效收集产物:通过气体收集器和液体收集器对产物进行高效分离和收集,减少产物的损失,从而提高能源利用效率。

  Efficient collection of products: By using gas and liquid collectors to efficiently separate and collect products, the loss of products is reduced, thereby improving energy utilization efficiency.

  回收利用热能:在热解气化过程中会产生大量热能,可通过能量回收技术,如余热利用、热交换等方式回收利用这些热能,进一步提高能源利用效率。

  Recycling thermal energy: During the pyrolysis and gasification process, a large amount of thermal energy is generated, which can be recovered and utilized through energy recovery technologies such as waste heat utilization and heat exchange, further improving energy utilization efficiency.
