Scope of application

It is suitable for the treatment of medical waste and other solid wastes with higher heating value.

Main technical content

First, the basic principle

According to the principle of pyrolysis, materials are heated under anoxic conditions to decompose the organic components in the waste and generate flammable gases. Because pyrolysis can generate combustible materials, in addition to the need for heating in the oven, there is basically no need to supply additional heat during the operation, which greatly reduces the fuel consumption required for incineration and achieves the goal of saving energy and reducing operating costs. Because a small amount of air is passed into the pyrolysis furnace and the temperature of pyrolysis is reasonably controlled, the amount of flue gas generated will be greatly reduced, and the content of harmful substances such as dust and heavy metals in the flue gas will be reduced. achieve.

Technical key

The system's main incineration equipment, a combustion chamber, is a pyrolysis furnace capable of continuous operation for 24 hours and automatic ash discharge. By controlling the furnace temperature and oxygen supply conditions of the pyrolysis furnace, the solid waste is dried, pyrolyzed, and burned out in the furnace. The burned ash is discharged through the ash discharge mechanism at the bottom of the furnace body to achieve continuous operation of the device. And automatically ash. Adopting advanced two British control technology and secondary pollution prevention technology, at the same time set explosion-proof, anti-scald, fire protection, electrical protection and emergency emergency linkage devices to ensure the safe operation of the equipment.
