Problems solved by technology

However, most of the existing incinerators currently have an incineration temperature between 600-800°C. The heat generated after incineration is not well utilized, and polluting gases such as dioxins are likely to be produced, which increases the cost of post-treatment gases. cost and pressure

Abstract

The invention belongs to the field of comprehensive utilization of solid waste resources, and particularly relates to a new medical solid waste utilization method and device. According to the method, medicine solid waste and pulverized coal are mixed and then put into a fluid-solid coupling combustion device to be incinerated, and heat and / or slag generated by incineration are / is recycled. According to the method and device, co-treatment of the medicine solid waste is realized on the basis of coal-fired power generation, the new treatment method is provided for treatment of the medicine solid waste, green and environment-friendly treatment of the solid waste is realized, generation of polluting gases such as dioxin in a traditional chemical organic solid waste incineration process is greatly reduced, and meanwhile, heavy metal elements in the solid waste are subjected to curing treatment. In addition, heat energy and slag generated by incineration can be well applied, and the win-win situation of economic benefits and environmental benefits is achieved. In addition, the method provided by the invention accords with the condition of existing solid waste, is beneficial to popularization in practice, and has important economic, social and ecological environmental protection significance.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of solid waste resources, and in particular relates to a new method and device for utilization of medical solid waste. Background technique [0002] Hospital waste is different from domestic waste. Medical waste contains a large number of bacteria, viruses, and chemicals, which are highly infectious, biologically toxic, and corrosive. Random piles of untreated or incompletely treated medical waste can easily cause damage to the environment. Pollution of water, soil and air can cause direct or indirect harm to the human body, and may also become the source of epidemics. With the current increase in population, people's living standards and medical standards have improved, and the amount of medical waste disposal has also increased year by year. The existing medical waste incineration system can no longer satisfy the effective, fast and safe disposal of medical waste, and further improvement...
