Medical waste subcritical hydrolysis processing apparatus

Abstract

The invention discloses a medical waste subcritical hydrolysis processing apparatus. The apparatus comprises: a raw material storage chamber, a subcritical hydrolysis processor, a heating casing, a steam concurrent boiler, an organic heat carrier boiler, an eddy flow deduster and a deodorizing unit. The apparatus is characterized in that: the outlet of the raw material storage chamber is connected with the inlet of the subcritical hydrolysis processor, the subcritical hydrolysis processor is connected with the eddy flow deduster via the outlet of the processor, the eddy flow deduster is connected with the deodorizing unit, the heating casing is installed on the lower portion of the subcritical hydrolysis processor, the steam concurrent boiler and the organic heat carrier boiler are connected with the subcritical hydrolysis processor and the heating casing respectively. The apparatus of the invention can be heated to the working temperature in a short time; achieves the advantages of low operation cost and low environment load; and can sterilize, damage, decrease, decompose a large amount of medical wastes completely under the high temperature and high pressure condition, and further dry and convert them into low molecular solid fuel with uniform texture, low content of impurity, no secondary pollution and gross calorific value.

Description

technical field [0001] The invention relates to a treatment device for infectious medical waste residues in the field of environmental protection technology, in particular to a subcritical hydrolysis treatment device for medical waste. Background technique [0002] Infectious medical waste, such as various internal organs, polyethylene, plaster, injection needles, etc., is infectious and damaging, and is harmful to human health. If discarded medical devices are not destroyed in time and are illegally sold into the society, it will cause the spread of diseases, potential threats to public health, public dissatisfaction, market disorder and other social hazards. [0003] Medical waste must be treated at high temperature before it can be completely harmless and meet the national environmental protection standards. The current main disposal technologies generally include high-temperature incineration, also known as pyrolysis incineration, chemical disinfection, high-temperature...

AI Technical Summary

Problems solved by technology

Although these technologies can completely destroy all kinds of bacteria, viruses, fungi and other sources of infection, they are prone to produce a large amount of volatile organic substances, especially the emission of dioxins during incineration and flue gas treatment. odor

In addition, the tail products after sterilization treatment or chemical disinfection treatment need to be finally landfilled. If the landfill treatment is not done properly, it may cause secondary pollution to soil, surface water, and groundwater.

[0004] At present, the temperature of conventional high-temperature pyrolysis medical waste devices is generally 500-700°C, and the process flow is relatively complicated. The heating and cooling process consumes a lot of time, and consumes a lot of heat sources through fuel oil, gas, coal, and electricity. The energy consumption of the device is relatively high; at the same time, the sealing system of the processing container is easily damaged, and the high-temperature gas in the container is easy to leak out, and the processing and maintenance costs of the overall device are relatively high; in addition, medical waste contains a large amount of Waste plastics and waste rubbers converted into valuable fuels are directly incinerated, which is a serious waste of energy resources. It is difficult to realize the harmless recycling and resource reuse of medical waste with existing technologies
