Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings 1 to 10 of the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.

The most common medical waste disposal methods are: three forms of landfill, microwave sterilization and incineration. Compared with other treatment methods, the medical waste incineration power generation has the advantages of small occupied area, thorough harmlessness, high resource utilization degree and the like. However, at the beginning of the project, china still faces a plurality of difficulties in the aspect of treating garbage by adopting an incineration method, which mainly shows that:

(1) The introduced technology is expensive and is difficult to adapt to the national conditions of China. The most and mature medical waste incineration treatment technology applied abroad is mainly a grate furnace. They have good incineration treatment effect on domestic garbage with high foreign heat value and low water content. However, according to practical operation experience, the directly introduced foreign grate furnace has the disadvantages of no pre-sorting in incineration treatment, complex components, lower heat value and unsatisfactory incineration treatment effect. Because the designed heat value of the incinerator is high, the garbage percolate generated in the stacking process needs to be additionally treated after being stacked for 3-7 days before entering the incinerator. At the same time, it is unacceptable for most of the Chinese towns, whose economic strength is not strong enough at present. In addition, the foreign grate furnace incineration technology generally adopts oil for combustion supporting, has higher operation cost and needs high government subsidies.

(2) The research on the generation mechanism and the control technology of the secondary pollution in the medical waste incineration process is lacked. The smoke discharged by the incineration of the medical waste contains various harmful and toxic substances such as SO2, HCl, HF, hg, pb, cd, NOx, dioxin, heavy metals and the like, and if a simple incineration method is adopted, serious secondary pollution can be caused. The 'clean' incineration of the domestic waste can be realized only by deeply researching combustion modes, combustion optimization, flue gas purification and other aspects and adopting a targeted technical means.

(4) The power generation efficiency of medical waste incineration needs to be improved. The power generation efficiency of the international medical waste incineration power plant is much lower than that of the modern thermal power plant. The main reason for the influence on the power generation efficiency is that chloride salts contained in combustion gas of the medical waste incineration boiler cause high-temperature corrosion of the superheater, so that the steam parameters of the waste incinerator are low, for example, the parameters of the waste incinerator are generally designed to be 2.94MPa and below 300 ℃ in Japan, and the steam parameters of Europe and America are generally 4.5MPa and below 450 ℃. Therefore, increasing steam parameters is a development direction for improving the economy of waste incineration.

(5) The medical waste incineration technology, particularly the integration technology, needs to be improved. The medical waste incineration system is integrated with various systems including waste pretreatment and feeding, an incinerator, waste heat utilization and power generation, flue gas purification, ash treatment and control systems. Since the development time of the medical waste incineration technology in China is still short, the integration and optimization of the medical waste incineration system need to be further improved.
