Equipment and Method for Intelligent Mobile Medical Waste Disposal and Flue Gas Purification

An intelligent mobile medical waste disposal and flue gas purification method, comprising:

• transporting medical waste to a location of an intelligent mobile medical waste disposal and flue gas purification equipment through an Internet of things garbage collection system, and
• automatically feeding a medical waste pyrolysis incineration system by an intelligent mechanical arm;
• selecting a pyrolysis process by a pyrolysis gasification chamber according to use requirements, and raising a temperature to a corresponding value through a rapid temperature-raising program and a rapid temperature increase and control module, realizing rapid pyrolysis and efficient volume reduction of medical waste;
• transporting pyrolysis gas discharged from a pyrolysis gasification chamber and pyrolysis condensate oil to a secondary combustion chamber to complete deep decomposition of volatile organic compounds, persistent organic pollutants and other difficult-to-remove organic components in flue gas;
• sending the flue gas from an outlet of the secondary combustion chamber to a heat exchanger to complete a waste gas heat exchange step, reducing a temperature from 850 degrees Celsius to 500 degrees Celsius, and using generated waste heat in a link of a de-whitening tower;
• completing a flue gas quenching step for flue gas from an outlet of the heat exchanger through a quencher, reducing the temperature from 500 degrees Celsius to 200 degrees Celsius;
• completing a flue gas dust removal step for flue gas from an outlet of the quencher through a dust collector;
• completing a flue gas deacidification step for flue gas from an outlet of the dust collector through a wet deacidification tower to remove acid gases such as hydrogen chloride, sulphur dioxide, nitrogen oxides, wherein a deacidification process uses a lye atomization spraying mode, and lye is a prepared sodium hydroxide solution;
• completing a flue gas dehydration and defogging step for flue gas from an outlet of the wet deacidification tower through a dehydrator;
• completing a flue gas de-whitening step for flue gas from an outlet of the dehydrator through a de-whitening tower;
• completing a low-temperature plasma molecular cracking deep purification step for flue gas from an outlet of the de-whitening tower through molecular cracking equipment, realizing efficient decomposition of trace dioxin and other difficult-to-remove pollutants by massive high-energy free radicals in a process of low-temperature plasma discharge, and ultimately ensuring a dioxin emission concentration of ≤0.3 nanogram toxic equivalent quantity/normal cubic metre;
• discharging flue gas from an outlet of the molecular cracking equipment to atmosphere through a chimney;
• and
• collecting at least fly ash and particulate matter filtered by the dust collector in internal ceramic fibre pipes, and sending at least fly ash and particulate matter to a specific site for landfill after a proper treatment;
• sending waste residue generated by the pyrolysis gasification chamber to a specific site for landfill after collection and pretreatment of spraying dust suppression;
• and recovering pyrolysis gas generated by the pyrolysis gasification chamber as condensed oil after condensation.
