A medical waste incinerator using oxygen-enriched combustion technology

Abstract

The invention discloses a medical waste incinerator applied with the oxygen-enriched combustion technology, and belongs to the field of environmental-friendly and energy-saving devices. The medical waste incinerator comprises an incinerator body, a second combustion chamber, a combustion air fan, an oxygen-enriched air supply system and a smoke tail processing system. Combustible components of medical waste are decomposed into combustible gas (smoke) in the incinerator body, and combustible gas enters a second combustion chamber body and flows downwards; the combustion air fan delivers combustion air into the incinerator body and the second combustion chamber body; the oxygen-enriched air supply system is used for generating oxygen-enriched gas and leading the oxygen-enriched gas into the second combustion chamber body; the smoke is contacted with the common combustion air and the oxygen-enriched gas which enters into the second combustion chamber respectively, turbulence and perturbation are formed in a main combustion zone by the smoke, and therefore the fact that waste gas burns out is facilitated. According to the medical waste incinerator applied with the oxygen-enriched combustion technology, the burning temperature of the waste gas of the incinerator is guaranteed to the maximum extent through oxygen-enriched equipment and a secondary air system, the second combustion chamber is facilitated to form turbulent flow, the staying time of the smoke in the second combustion chamber is prolonged, and therefore dioxin is decomposed.

Description

technical field [0001] The invention relates to the technical field of environmental protection and energy saving devices, in particular to a medical waste incinerator applying oxygen-enriched combustion technology. Background technique [0002] Medical waste is a kind of polluting, harmful and deadly medical waste. The national "Hazardous Waste List" clearly states that medical waste is No. 1 hazardous waste. The National Law on the Prevention and Control of Environmental Pollution by Solid Waste regards the promotion of centralized disposal of hazardous waste as the basic principle and important measure for the prevention and control of hazardous waste. But in fact, due to various reasons, a considerable amount of medical waste has not been effectively and timely disposed of. Medical waste contains a large number of pathogenic bacteria, viruses, radioactive substances and more chemical poisons, etc., and is extremely infectious, biologically viral and corrosive. The har...

Problems solved by technology

In fact, the oxygen content at the outlet of the incinerator is guaranteed to be above 6-10% or greater than this value, and it is not easy to ensure the temperature of the secondary combustion chamber, and the supplement and improper control of the combustion air volume during the combustion process of the secondary combustion chamber cannot guarantee the temperature above 1100 °C.
