Description
Technical Field
The utility model relates to a refuse treatment technical field especially relates to a refuse treatment equipment.
Background
At present, domestic garbage treatment methods suitable for treating domestic garbage mainly comprise incineration, high-temperature pyrolysis and low-temperature pyrolysis. The method for treating the garbage by burning not only greatly reduces the volume of the garbage, but also can generate electricity and supply heat by using the heat generated by burning so as to achieve the purpose of recycling energy. However, direct incineration of garbage has many problems, for example, because the heat value of household garbage is low, auxiliary energy needs to be added when incineration equipment incinerates garbage to ensure normal operation of the incineration equipment; in addition, the smoke generated by the waste incineration is complex in composition and difficult to treat, and the environment can be polluted due to improper treatment, for example, acidic gas, highly toxic chlorine-containing high molecular compounds (generally called dioxin substances), mercury-containing smoke dust and lead-containing smoke dust and the like can be generated by the organic waste incineration.
In order to overcome the above-mentioned disadvantages of the waste incineration technology, a waste pyrolysis technology as a substitute technology for waste incineration has been developed and applied. Pyrolysis, which is different according to the control conditions of the pyrolysis process, can be classified into high-temperature pyrolysis and low-temperature pyrolysis. The high-temperature pyrolysis refers to a process of heating and decomposing solid organic garbage under the condition of completely isolating oxygen, and is a pyrolysis process in a strict sense. The low-temperature pyrolysis is to supply a certain amount of air and water vapor into the pyrolysis equipment to partially combust combustible substances in the organic waste and decompose the organic waste by using heat generated by combustion, and the whole pyrolysis process can be automatically and continuously carried out without external heat source supply.
Although the normal operation of the furnace body can be ensured without external energy sources through high-temperature pyrolysis, harmful gases such as nitrogen oxides, dioxin and the like can be generated through high-temperature decomposition, and the treatment cost is higher. The low-temperature pyrolysis equipment carries out garbage pyrolysis at the low temperature of 300 ℃, can avoid the generation of dioxin, and has the advantages of simple and easy-to-process smoke components, low operation cost and the like. However, in the actual operation process of the low-temperature pyrolysis equipment, due to the reasons of different moisture degrees of the garbage, different garbage components and the like, the temperature in the furnace is uncontrollable in the pyrolysis process, so that the local temperature sometimes exceeds 300 ℃, and when the temperature exceeds 300 ℃, harmful substances such as dioxin and the like can be generated by decomposing the garbage. In addition, because the low-temperature pyrolysis equipment belongs to anoxic decomposition equipment during operation, CO can exist in flue gas generated by pyrolysis, and the CO in the atmosphere can exceed the standard when the flue gas is discharged into the air.
