Title:
TREATMENT OF EXHAUST GAS GENERATED BY HEAT-TREATMENT OF MEDICAL WASTE
Document Type and Number:
Japanese Patent JP2530529
Kind Code:
B2
Abstract:
PURPOSE: To make exhaust gas harmless and odorless with high efficiency by removing hydrogen chloride in exhaust gas generated when medical waste mainly constituted of plastics is subjected to heating/sterilizing treatment by a reactive adsorbent before subjecting combustible gas and malodorous gas to oxidative decomposition.
CONSTITUTION: A hydrogen chloride gas adsorbing cylinder 12 is provided to a medical waste treatment apparatus 10 wherein medical waste mainly constituted of plastics such as used synthetic resin products, for example, a syringe, an injection needle or the like is received in a heat-resistant container and heated to predetermained temp. to be sterilized and the exhaust gas generated from the treatment apparatus 10 is guided to the adsorbing cylinder 12 to be brought into contact with a reactive adsorbent composed of oxides of group I, II, VII elements of the Periodic Table to remove hydrogen chloride gas. Next, the exhaust gas is heated to temp. suitable for catalytic oxidative decomposition by a heater 14 to be guided to a catalytic oxidizing cylinder 16 and brought into contact with a Pt or/and Pd type catalyst to subject the combustible gas and malodorous gas in the exhaust gas to oxidative decomposition.
