Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

Referring to fig. 1, the embodiment of the utility model discloses a medical waste microwave carbonization innocent treatment device, which comprises a microwave generator 100, a carbonization bin 400, a vibrating screen 500 and a granular carbon device 600 which are connected in sequence;

the gas outlet of the microwave generator and the gas outlet of the carbonization bin are respectively connected to the flue gas condensation equipment 700. Further, an automatic conveying belt 200 and a feeding device 300 are sequentially arranged between the microwave generator and the carbonization bin. Further, the gas outlet of the flue gas condensing equipment is communicated with a combustion chamber 810. Further, the gas outlet of the combustion chamber is communicated with a tail gas treatment device 900. Further, the tail gas treatment device comprises a washing tower 910, a demister 920 and a UV ozone purifier 930 which are connected in sequence. Further, the UV ozone purifier comprises a shell, and a UV generation unit and an ozone generation unit which are installed in the shell. Further, a gas generator 820 is arranged on the heat supply side of the combustion chamber, power is generated by using heat energy generated by combustion, and a power supply end of the gas generator is electrically connected with the microwave generator.

The medical waste is prepared by controlling the temperature of a microwave generator by an automatic program PLC (programmable logic controller), controlling the temperature between 400 ℃ and 600 ℃, passing the material through an automatic conveying belt (the automatic conveying belt is a chain type or a roller type made of metal in view of high temperature resistance), a feeding system (various elevators and needless of course without the help of the feeding system) conveying the material which does not need to be crushed into a carbonization bin, carbonizing the material at 600 ℃, reducing the volume by 70 percent, removing 25 percent of carbon slag by a vibrating screen in the rest 30 percent, compressing the rest 30 percent into granular carbon by a granular carbon device to be used as a heating material, and finally, the rest 5 percent is glass and metal and can be reused.

The smoke generated by microwave carbonization of medical waste is condensed by smoke condensing equipment to generate a part of biodiesel which can be recycled for industrial oil, and a small part of combustible gas is automatically combusted at 1100 ℃ by a torch nozzle. Or used for generating electricity by a gas generator and supplying power to a microwave generator. The micro flue gas is treated for the first time by a washing tower (such as a physical ball small water-cooled type) to remove dust. And then the water is removed through a small demister, and finally the water is discharged after reaching the standard through UV ozone purification treatment.

The treatment capacity of the equipment is determined according to the power of the microwave, and the total power of 10 tons of medical wastes treated is about 180 kilowatts. The microwave heating function is that each group of the microwave heating function circularly works according to the use temperature, namely the normal use of the machine is completely less than 180 kilowatts, so that the energy is saved, the emission is reduced, and the heating part belongs to the microwave source heating and has no flue gas treatment.
