Pressurized and heated medical waste classification and pyrolysis device

Abstract

The invention discloses a pressurized and heated medical waste classification and pyrolysis device. During pyrolysis, running water in a water tank is heated by high-temperature ash, the interior of avapor chamber is heated under the effect of a circulating water pump, the ash temperature is reduced, the heat is reutilized, and energy is saved; metal parts in medical wastes transferred by a transfer device are adsorbed onto a conveyor belt under the action of a rubber magnetic stripe and finally enters the vapor chamber under the action of a scraper, the metal parts are classified from otherwastes, and damage of each part in a pyrolyzing furnace is effectively avoided. A compressed panel is downwards pushed by an oil hydraulic cylinder, and air in the pressurization device further entersthe tank, so that the pressure in the tank is raised, the temperature in the tank body is further improved, the pyrolysis temperature is ensured, the temperature of the running water in the water tank is improved, and a high-temperature and high-pressure sterilization environment in the vapor chamber is further ensured.

Description

technical field [0001] The invention relates to medical waste treatment, in particular to a pressurized and heated medical waste sorting and pyrolysis device. Background technique [0002] Medical waste refers to polluting waste produced by hospitals that have been in contact with patients' blood and flesh. Such as used cotton balls, gauze, tape, waste water, disposable medical equipment, postoperative waste products and expired medicines, etc. According to the medical inspection report of the national health department, because medical waste has the characteristics of space pollution, acute infection and latent pollution, the harmfulness of viruses and bacteria is dozens, hundreds or even thousands of times that of ordinary domestic waste. If it is not handled properly, it will cause serious pollution to the environment and may also become the source of epidemics. [0003] Most of the existing treatment methods are incineration and landfill. Incineration is likely to caus...

If it is not handled properly, it will cause serious pollution to the environment and may also become the source of epidemics

[0003] Most of the existing treatment methods are incineration and landfill. Incineration is likely to cause secondary pollution, and landfill cannot completely avoid the spread of bacteria. Pyrolysis is a better treatment method than the above two methods, but the existing The pyrolysis device cannot classify the garbage. When the medical waste doped with metal parts is pyrolyzed for classification, it is easy to cause damage and blockage of the equipment, and the separate classification treatment has caused low efficiency.
