Embodiment 1

[0024] An environmentally friendly treatment method for medical waste, including the following steps:

[0025] The separately weighed raw coal and the preliminarily screened and crushed medical waste are sent to the raw coal bunker for mixing through the conveyor belt. The mass ratio of the medical waste to the raw coal is 1:8, and then the pulverizing system performs coarse crushing and ball milling to The fineness of the material is R90=16-20% and is sent to the pulverized coal silo. The pulverizer adjusts the speed according to the load of the heating boiler, and sends the crushed mixture into the cyclone furnace to burn to the molten state at 1600℃. The resulting molten substance is in contact with water in the granulation box at 20°C for cold quenching to form a non-toxic and side-effect glass body, and then the slag flushing pump sprays the pressurized water to remove the glass body in the granulation box Rush to the slag ditch and flow to the slag tank. The slag grab grabs...

Embodiment 2

[0029] An environmentally friendly treatment method for medical waste, including the following steps:

[0030] The separately weighed raw coal and the preliminarily screened and crushed medical waste are sent to the raw coal bunker for mixing through the conveyor belt. The mass ratio of the medical waste to the raw coal is 1:9, and then the pulverizing system performs coarse crushing and ball milling to The fineness of the material is R90=16-20% and it is sent to the pulverized coal silo. The pulverizer adjusts the speed according to the load of the heating boiler, and sends the pulverized mixture into the cyclone furnace and burns to the molten state at 1800℃. The resulting molten substance is in contact with water in the granulation box at 25°C for cold quenching to produce a non-toxic and side-effect vitreous substance, and then the slag flushing pump sprays the pressurized water to remove the vitreous substance in the granulation box Rush to the slag ditch and flow to the sla...

Embodiment 3

[0034] An environmentally friendly treatment method for medical waste, including the following steps:

[0035] The separately weighed raw coal and the preliminarily screened and crushed medical waste are sent to the raw coal bunker for mixing through the conveyor belt. The mass ratio of the medical waste to the raw coal is 2:10, and then the pulverizing system performs coarse crushing and ball milling to The fineness of the material is R90=16-20% and is sent to the pulverized coal silo. The pulverizer adjusts the speed according to the load of the heating boiler, and sends the crushed mixture into the cyclone furnace to burn to the molten state at 2000 ℃. The obtained molten substance is in contact with water at 28°C in the granulation box for cold quenching, forming a non-toxic and side effect glass body, and then the slag flushing pump sprays the pressurized water to remove the glass body in the granulation box Rush to the slag ditch and flow to the slag tank. The slag grab gra...

Abstract

The invention belongs to the field of heavy metal pollutant treatment and particularly relates to an environment-friendly treatment method of medical garbage.By the adoption of coal powder, high-dielectric heavy metal in the medical garbage is reduced into non-toxic low-dielectric heavy metal under the high-temperature condition, the low-dielectric heavy metal is sealed up in a final product glass body object, exhausted smoke is separated, collected and treated again, and the medical garbage can be treated in a complete environment-friendly mode really.Meanwhile, heat generated by combustion of the coal powder and the medical garbage can serve as a heat source of a heating boiler, and energy sources can be distributed reasonably and applied in an environment-friendly mode.

Description

technical field [0001] The invention belongs to the field of treatment of heavy metal pollutants, in particular to an environmental protection treatment method of medical waste. Background technique [0002] With the rapid development of industrial civilization, the pollution caused by heavy metals is deteriorating step by step, especially the environmental pollution caused by medical waste. Most of the medical waste in the prior art is processed by high-temperature incineration, so the heavy metals in the medical waste are either discharged into the atmosphere along with the smoke, or remain in the burned ash and are transported to the garbage dump, causing damage to the soil. pollute. Therefore, how to carry out environmental protection treatment of medical waste is a technical problem to be solved urgently by those skilled in the art. [0003] The heavy metal waste in the prior art mostly adopts engineering restoration measures, chemical restoration measures or biologic...
