Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of ventilation system. More particularly, it relates to a ventilation system device of a waste incineration equipment for incinerating waste and other combustibles. BACKGROUND

[0002] The waste incineration equipment, such as a modern waste incinerator, is used to incinerate waste. The waste is fed into the incinerator through a feeding port. The feeding process can be continuous or intermittent, depending on the type and size of the incinerator. The waste is subjected to high temperature and sufficient oxygen in the furnace, and starts to burn. The grate or stirring device continuously turns and stirs the waste to ensure its complete combustion. The heat generated during the combustion process is recovered by the waste heat recovery system. The flue gas generated during the combustion process is purified by the flue gas treatment system. The solid waste, such as slag and fly ash, generated by the incinerator is treated further, such as landfill or resource utilization. The waste incineration equipment can quickly and efficiently treat municipal solid waste, reducing the pressure on the landfill site. Through the flue gas treatment and waste heat recovery system, the harmful gases and heat generated during the incineration process are effectively controlled and utilized. The solid waste, such as slag and fly ash, generated during the incineration process can be further utilized, such as making building materials.

[0003] As the ventilation system of the waste incineration equipment, it is crucial for the stable operation and efficient combustion of the waste incinerator.
