[0038] like Figure 1 and Figure 2 As shown, a specific embodiment is used to explain below. The present invention provides a method for treating medical waste for ships.

[0039] Medical waste is crushed, sorted and packaged before being put into the incinerator. After the incinerator's feeding port is tightly closed to prevent medical waste from polluting the air during the incineration process, the medical waste in the incinerator is cracked in an oxygen-deficient atmosphere using the microwave heating principle.

The medical waste in the incinerator is cracked in an oxygen-deficient atmosphere using the microwave heating principle, and the medical waste is cracked into gas, liquid and solid three-phase states, and the medical waste is cracked into water vapor, high-temperature flue gas and carbon slag.

[0040] The water vapor produced by the decomposition evaporates with high temperature, and the high-temperature flue gas in the incinerator enters the exhaust gas incineration chamber and is incinerated at high temperature through the heating medium.

[0041] The flue gas after high-temperature incineration stays in the high-temperature medium channel for a certain period of time and then enters the terminal exhaust gas processor.

[0042] The flue gas after high-temperature incineration is mixed with air in the terminal exhaust gas processor to achieve a qualified stoichiometric ratio.

[0043] The flue gas after high-temperature incineration is mixed with air in the terminal exhaust gas processor, and the flue gas after high-temperature incineration is cooled by the cooling system and discharged after reaching the standard. The cooling system is a fan.

[0044] Furthermore, the carbon slag is discharged through the outlet of the incinerator.

[0045] It can be seen from the above scheme that the present invention provides a method for treating medical waste for ships, which solves the problem of incomplete combustion of medical waste or secondary pollution of the atmosphere caused by exhaust of flue gas into the atmosphere.

[0046] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
