Description

High-temperature steam sterilization device for treating medical waste

Technical Field

The invention relates to the technical field of garbage treatment, in particular to a high-temperature steam sterilization device for treating medical wastes.

Background

Hospital waste refers to all waste that a hospital needs to discard and cannot be reused, and includes biological and non-biological, and also includes domestic garbage. Medical waste refers to waste generated during the course of a patient's activities of diagnosis, treatment, care, and the like. Medical waste may contain a large amount of pathogenic microorganisms and harmful chemicals, and even radioactive and damaging substances, and thus is an important risk factor for disease transmission or related public health problems.

Most of the existing medical waste treatment methods firstly adopt a high-temperature steam method to carry out sterilization treatment. However, in the existing device, the steam source is basically provided externally, heat dissipation is very easy to occur in the transmission process, and the energy-saving effect of the device is poor. Meanwhile, steam is continuously supplied from an external source, so that a large amount of water is undoubtedly introduced in the garbage treatment, more waste water is generated, and the cost of the waste water treatment is greatly increased. In the existing device, garbage can be stacked together in the garbage treatment, and an area where steam cannot reach exists, so that the garbage is not sufficiently sterilized, and the potential safety hazard is large.
