Medical waste microwave treatment method and treatment equipment

Abstract

The invention provides a medical waste microwave treatment method and treatment equipment. The medical waste microwave treatment method comprises the steps that the temperature of medical waste is increased by means of microwaves till the medical waste is incinerated; and then ionizing decomposition is conducted on gas generated in the incineration process of the medical waste in a high-voltage electric field, so that harmful substances left in the gas are removed. The equipment is composed of a medical waste feeding system, a microwave incineration furnace, a gas filtering system, a plasma gas processing system, a gas energy reutilization loop and a gas cooling system, wherein the microwave incineration furnace, the gas filtering system, the plasma gas processing system, the gas energy reutilization loop and the gas cooling system are connected with one another in sequence through gas delivery pipelines. The medical waste microwave treatment method and the treatment equipment have the advantage that minimizing, harmless, efficient, energy-saving and environment-friendly treatment of the medical waste can be achieved.

Description

technical field [0001] The invention belongs to the field of microwave technology, and in particular relates to a microwave processing method and processing equipment for medical waste. Background technique [0002] Traditional medical waste treatment methods mainly include chemical treatment methods and physical treatment methods. The chemical treatment method mainly adopts sanitary landfill method, which is to bury medical waste in deep soil and use microorganisms to decompose naturally. However, medical waste is not easy to decompose for hundreds of years in the absence of light and wind erosion. Because plastic, glass, rubber, and aluminum products are all inorganic substances, it takes a long period of time to achieve the goal of natural decomposition by microorganisms alone, and it will also trigger There are many disadvantages such as soil acidification and compaction, pollution of groundwater resources, and occupation of land resources. The physical treatment metho...

Problems solved by technology

However, the composition of medical waste is complex, containing a large amount of plastic, rubber and other products. The treatment temperature of traditional incinerators is low (up to 1000°C), generally 700-800°C, and it takes a long time for the temperature to rise from 200°C to 500°C. , will produce a large amount of highly toxic gases such as "dioxin", which will seriously affect the atmospheric environment and people's health. Therefore, the flue gas pollution generated by medical waste incineration has always been a key problem to be solved in incineration technology

Moreover, the traditional medical waste incinerator device cannot be directly built in the hospital. Medical waste needs to be sorted and packaged before being transported to the incineration plant for centralized treatment. It is easily scattered during transportation, causing the environment to be polluted again
