Efficient treatment device for medical waste

Abstract

The invention discloses an efficient treatment device for medical waste. The efficient treatment device comprises a reaction chamber, a reaction chamber, an air blower, a waste residue chamber and an oxygen-enriched air supply system, wherein the reaction chamber is arranged above the waste residue chamber; the reaction chamber and the waste residue chamber form a device tower body; a filter residue screen plate is arranged between the reaction chamber and the waste residue chamber; and a piston feeding device is arranged at the side of the upper end of the reaction chamber. The medical waste is pyrolyzed under an anaerobic condition in the reaction chamber to generate combustible gases and harmless residues, combustion treatment is carried out on the combustible gases in the combustion chamber, and concentrated collection treatment is carried out on the harmless residues, thus generation of harmful gases due to direct combustion is avoided; an oxygen-enriched gas is conveyed in the combustion chamber through the oxygen-enriched air supply system to adjust an oxygen content in the combustion chamber, thus adequate combustion of the different combustible gases is ensured; and a tail gas after the adequate combustion is filtered through a tail gas treatment device, and then clean air is exhausted and is harmless to environment.

Description

technical field [0001] The invention relates to the field of special waste treatment, in particular to a high-efficiency treatment device for medical waste. Background technique [0002] Medical waste is a special urban pollutant, specifically referring to the waste generated from the medical service process of hospitals, medical centers and clinics. Because medical waste contains a large number of viruses, bacteria and chemicals, it is a kind of hazardous waste that is extremely harmful to the environment and public health safety. It has been included in the "Basel Convention" that controls the transfer of hazardous waste internationally. It was included in the first batch of "National Hazardous Waste List" in 1998, and it is required to be treated as hazardous waste. In the existing technology, medical waste is directly incinerated by traditional combustion methods, which has large fluctuations in combustion conditions and incomplete combustion. And unstable, it will prod...

Because medical waste contains a large number of viruses, bacteria and chemicals, it is a kind of hazardous waste that is extremely harmful to the environment and public health safety. It has been included in the "Basel Convention" that controls the transfer of hazardous waste internationally. It was included in the first batch of "National Hazardous Waste List" in 1998, and it is required to be treated as hazardous waste. In the existing technology, medical waste is directly incinerated by traditional combustion methods, which has large fluctuations in combustion conditions and incomplete combustion. And unstable, it will produce harmful and toxic substances such as black smoke, particulate matter and dioxin, which will bring secondary pollution and harm to the environment
