6. a kind for the treatment of of!medical waste method based on the treatment of!medical waste device described in claim 1 is it is characterised in that institute
The method of stating comprises the steps:
In sorting case, medical waste is tentatively sorted, sorted out inorganic including relatively large metal and glass
Thing, and it is indoor that medical waste after the completion of sorting is pushed to preheating and drying；
First high-temperature flue gas entry receives the high-temperature flue gas from the second temperature controlled compartment, controls the first temperature by the first temperature sensor
The temperature of control room, makes the indoor medical waste of preheating and drying enter the preheating and drying stage, to the moisture being comprised in medical waste
It is evaporated volatilization preliminary exposition, then the gas decomposing is passed through the first decomposed gas outlet and discharge, simultaneously by high temperature
The tail gas of flue gas is discharged by offgas outlet, and the medical waste after preheating and drying is processed is pushed to low-temperature carbonization room；
Second high-temperature flue gas entry receives the high-temperature flue gas from temperature control Burning Room, controls the second temperature by second temperature sensor
The temperature of control room, makes the indoor medical waste of low-temperature carbonization enter low-temperature carbonization stage, medical waste is carried out at low-temperature carbonization
Then the gas decomposing passed through the second decomposed gas outlet and discharge, high-temperature flue gas are passed through the first high-temperature flue gas simultaneously by reason
Outlet is sent to the first high-temperature flue gas entry of the first temperature controlled compartment, and the medical waste after low-temperature carbonization is processed is pushed to high temperature
Carbonizing chamber；
Temperature control Burning Room by decomposition gas entrance receive first decompose lift outlet and second decomposed gas outlet discharge can
The decomposition gas of combustion property, and control burning, form high-temperature flue gas, by the second high-temperature flue gas outlet, high-temperature flue gas are conveyed simultaneously
To the second high-temperature flue gas entry of the second temperature controlled compartment, then control the temperature of temperature control Burning Room by three-temperature sensor, make
The indoor medical waste of high temperature cabonization enters the high temperature cabonization stage, carries out high temperature cabonization process to medical waste, and by pyrocarbon
Medical waste after change is processed is pushed in separatory vessel；
In described separatory vessel, the residue after high temperature cabonization process is entered with the recovery of row metal and carbon granules.
7. treatment of!medical waste method according to claim 6 is it is characterised in that methods described also comprises the steps:
It is arranged on the indoor first heater of described first temperature control to be preheated, make preheating and drying room reach preheating and drying rank
Temperature required for section.
8. treatment of!medical waste method according to claim 6 is it is characterised in that methods described also comprises the steps:
Exhaust gas processing device carries out dust removal operation to the low-temperature flue gas discharged from the offgas outlet of described first temperature controlled compartment, and will remove
Exhaust emissions after dirt operation is in air.
9. treatment of!medical waste method according to claim 6 is it is characterised in that methods described also comprises the steps:
First heat exchanger tube burns interior in temperature control and carries out heat exchange, and the second heat exchanger tube carries out heat exchange in the second temperature control interior；
The medical treatment in disinfection heat exchanger to the heat exchange of the first heat exchanger tube and the second heat exchanger tube respectively of 3rd heat exchanger tube
In sewage, carry out disinfection sterilization to medical sewage.
