The working process of medical incinerators can be roughly divided into the following stages:
Pretreatment stage:
Before entering the incinerator, medical waste will undergo a series of pretreatments, such as sorting, crushing, compaction, etc. The purpose of this step is to remove non-combustion substances from garbage, reduce the volume of garbage, and improve incineration efficiency.
Objective:
To ensure the efficient and stable operation of the incinerator, while reducing wear and damage to the incinerator.
Incineration stage:
Pre-treated medical waste is sent into the incinerator and completely burned through high temperature combustion. During the incineration process, the incinerator will control the combustion temperature, combustion time and other parameters to ensure that the garbage is fully burned.
Key parameters:
The incineration temperature usually needs to reach more than 850°C to ensure that pathogens, harmful chemicals, etc. in medical waste are completely destroyed.
Flue gas purification stage:
The flue gas produced by incineration contains a large number of harmful substances, such as particulate matter, acidic gas, heavy metals, etc. The flue gas purification system will treat these harmful substances to reduce their pollution to the environment.
Purification technology:
including dust removal, desulfurization, denitrification, heavy metal removal and other technologies to ensure that flue gas emissions meet national and local environmental protection standards.
Ash treatment stage:
The ash generated after incineration will be collected for harmless treatment or safe landfilling. The handling of ash should follow relevant environmental regulations and standards to ensure that it does not cause harm to the environment and human health.
Harmless treatment
Through high-temperature incineration, pathogens, chemicals, radioactive substances and other harmful substances in medical waste are completely incinerated and converted into harmless substances.
Reduced treatment: During incineration, the volume of medical waste will be greatly reduced, thus reducing the occupation and pollution of garbage on the environment.
Resource utilization
The thermal energy generated during incineration can be recycled through heat exchange technology for heating or power generation to achieve the sustainable use of resources.
Environmental protection and safety
Medical incinerators adopt advanced combustion technology and equipment, which can effectively control exhaust emissions and secondary pollution and ensure environmental protection and safety in the treatment process.
