The basic principle of the special energy household waste pyrolysis gasification power generation system is to convert household waste and other waste into combustible gas through a gasification furnace after pre-treatment, and then use combustible gas as fuel for gas boilers. After producing steam, the steam drives the steam turbine to work and generate electricity. It can solve the increasingly serious problem of ineffective harmless and reduced treatment of urban household waste, making it one of the more effective and clean utilization methods for waste treatment.

一阶段垃圾预处理

Stage 1 Garbage Pretreatment

垃圾预处理主要设备包括：输送带、分选设备等。整个工艺流程为：垃圾经过人工，去除一些大物件（进一步破碎后用于热解气化）、可回收物品、有害物品等；再经过滚筒筛设备分选，得到可用于热解气化的可燃物（纸制品、木制品、园林修剪枝丫、纺织物、无害塑料等）。有机垃圾可用作沼气或者堆肥处理，金属、玻璃等可回收垃圾可回收处理。

The main equipment for garbage pretreatment includes conveyor belts, sorting equipment, etc. The entire process flow is as follows: the garbage is manually removed from some large objects (further crushed for pyrolysis and gasification), recyclable items, harmful substances, etc; After being sorted by a drum screen equipment, combustible materials (paper products, wood products, garden pruning branches, textiles, harmless plastics, etc.) that can be used for pyrolysis and gasification are obtained. Organic waste can be used for biogas or composting treatment, while recyclable waste such as metal and glass can be recycled for treatment.

二阶段气化发电

Two-stage gasification power generation

气化发电系统的主要设备包括：加料与送料设备、气化炉、燃气锅炉、汽轮机、烟气处理系统等。整个工艺流程基本分为：预处理的垃圾进入气化炉热解气化，固体燃料转变为可燃气体；可燃气体作为燃气锅炉燃料，生产蒸汽；蒸汽推动汽轮机稳定工作输出电能；锅炉烟气经过净化后排放。

The main equipment of the gasification power generation system includes: feeding and feeding equipment, gasification furnace, gas boiler, steam turbine, flue gas treatment system, etc. The entire process is basically divided into: the pre-treated waste enters the gasification furnace for pyrolysis and gasification, and the solid fuel is converted into combustible gas; Combustible gas is used as fuel for gas boilers to produce steam; Steam drives the stable operation of the steam turbine to output electrical energy; The boiler flue gas is discharged after purification.
