DE2505185A1 - Infected garbage removal from hospitals - includes treating with steam, infrared radiation and fluid bed heating - Google Patents

Abstract

A system for removal of infected (infectious) garbage waste etc. from in partic. hospitals, has a disinfection system in which the garbage or waste can be rendered free from disease carrying germs etc. to allow it to be handled in a normal manner. The process of disinfection may be continuous or discontinuous. In the latter process hot air or steam chambers are used. In the former or continuous process a rotating heated shaft with a communication device and output compaction press is used in conjunction with infra red or fluid bed type heating devices.

Description

Process for the disposal of infected (infectious) garbage, in particular from hospitals.

The rubbish that arises in hospitals, medical practices, etc. is marked through the possibility of being a carrier of pathological germs to the source of infection to become. That is why it is compulsory to keep this garbage on the hospital premises to destroy.

On the other hand, this garbage contains parts, e.g. glass or plastics, which make incineration very difficult, especially with regard to environmental protection only with enormous additional effort (filter and gas scrubbing).

The invention proposes to disinfect and pathological garbage to be treated like household waste, i.e. to be stored in an orderly manner or mixed together incinerate with household waste from other sources.

The disinfection of devices and devices is state of the art (Hot air from 18com, moist heat from 1200C / latü or high pressure steam 1340C / 2atü.

According to the invention, a hot air or superheated steam chamber can be used for this purpose into which the garbage is placed in bins.

However, continuous operation should preferably be aimed for: For this purpose, according to the invention, a tubular hot air (or superheated steam) Chamber used, which rotates at an angle and is constant transport and so the ensures that the goods to be disinfected remain in place over time. So treated Waste is pressed at the exit - if necessary to reduce its volume - for normal waste disposal guided.

Basically this is the case with appropriate interpretations of the technical Data ensures perfect disinfection. To get a better flow Achieving even narrower cross-sections should be done before or during the disinfection process comminution can be provided, for example in the form of a grinding process. Special problems offer metallic tubes such as syringes and hollow needles, in which e.g. Dried blood-smeared residues are contained. These would affect the grinding process withdraw, and even cause additional problems in the case of cross-sectional squashing.

To correct this problem, an infrared radiation source or Eddy current heating additionally spec. for heating the tietal parts.
