Does domestic waste incineration require air compressors for heating?
Air compressor is needed during domestic waste incineration and heating process, its role is mainly reflected in the following aspects:
- Providing compressed air for critical operations in incineration systems: During the combustion process of the incinerator, compressed air generated by the air compressor is injected into the furnace exhaust hole and mixed with the garbage for combustion. This design not only improves combustion efficiency, but also allows garbage to be suspended in the air to ensure adequate combustion. For example, mechanical grate incinerators use staggered grates and pulsed aerodynamic devices to push garbage to be thrown step by step into the next grate, completing the evaporation, cracking and combustion processes at high temperatures, and compressed air is the key element of maintaining this efficient combustion model.
- Driving pneumatic equipment guarantees process flow: The flue gas treatment system of waste incineration plants relies on compressed air driven pneumatic valves, pulse blowing devices of bag dust collectors and other equipment. These equipment achieve rapid action and precise control through compressed air. For example, bag dust collectors use compressed air to regularly clean ash to maintain efficient filtration performance. In addition, when the automated robot arm handles wafers and other materials, it also uses compressed air to drive the pneumatic gripper to complete the grasping and releasing actions to ensure the continuity and stability of the process process.
- Optimize energy efficiency: Some incineration plants use compressed air-driven energy-saving equipment, such as a combined system of steam air preheater and flue gas air preheater. The compressed air increases the temperature of the combustion-supporting air during the preheating process, making the garbage burn more fully, and at the same time, through waste heat recovery, steam is generated for heating or power generation. This design not only improves energy utilization efficiency, but also reduces energy waste, which is in line with the resource goal of waste incineration and heating.
- Support automated control and safety monitoring: The compressed air provides power to the DCS control system of the incineration plant, realizing real-time monitoring of more than 500 parameters such as furnace temperature, flue gas composition, and material layer thickness. By introducing AI algorithms, the system can respond to combustion adjustment requirements within 30 seconds to ensure process stability. At the same time, the compressed air-driven safety interlock device can monitor more than 200 protection parameters such as furnace negative pressure and gas leakage to ensure the safe operation of the incineration process.
