The collection, transportation and safe disposal of medical waste and epidemic household garbage are important contents for epidemic prevention and control and also an important part for blocking an epidemic propagation chain. As the processing capacity of the medical waste centralized disposal facilities which are built and put into use in China is limited, after the epidemic situation of the major infectious diseases occurs, the medical waste and the epidemic household garbage are greatly increased, and the emergency disposal facilities need to be started to meet the processing requirements of the medical waste. The main technical requirements of the household garbage incinerator and the medical waste incinerator are the same, the working condition requirements are close, the emergency disposal resource list of the medical waste is brought into the household garbage incinerator, and an implementation case is already provided during the epidemic situation of the novel coronavirus pneumonia.
The material loading mode that current domestic waste burns power plant and adopts when emergency treatment medical waste is: feeding by directly and manually tipping a bucket through an overhaul elevator; or unloading the medical waste after the reinforced packaging to a garbage pit, grabbing the material by using a hook and a string bag in a matching way (without a grab bucket, avoiding damage in the grabbing process), and guiding refined feeding by video monitoring. The mode of artifical tipping bucket feeding needs to add oblique platform in burning furnace feeder hopper department and is convenient for transport medical waste to the feed inlet, and material loading degree of automation is low, and intensity of labour is big, and has increased the risk of personnel's infection. The medical waste after will reinforceing the packing is unloaded to the rubbish hole after with the feeding mode of the supporting grab material of crotch and string bag need carry out special transformation to rubbish grab bucket crane, and the transformation degree of difficulty is big, and the operation flexibility is poor, and the medical waste of saving in rubbish hole inside subregion is difficult for snatching, causes medical waste to stop for a long time in the rubbish hole easily, leads to packing damaged infectious substance to leak even. Both of the two feeding methods have strict requirements on the packaging of medical waste; meanwhile, the blending combustion proportion of the medical waste is not easy to control in the two feeding modes. Because the medical waste has high calorific value and low ignition point, the furnace feeding time is concentrated, and the ignition point is concentrated during combustion, the operation fluctuation of the incinerator is easily caused when the medical waste is treated by adopting the existing feeding mode, and the problems of falling of refractory materials in the incinerator, damage of a fire grate and a superheater and the like can be caused after long-time operation, so that the equipment maintenance and the operation cost are increased.
