PI Incinerator Series

The PI Incinerator Series consists of nine sub-systems by the order of its technology process, i.e. The Feeding System, Incineration System, Fuel System, Air Supply System, Emergent Emission Chimney, Gas-cleaning System, Slag Disposal System, Fly Ash Solidification System and Auto Control System.

The incinerator combines the following characteristics:

  1. 1. The waste is directly incinerated without prior assortment, selection and grinding. It is a highly mechanized and automated technology with low labor intensity.
  2. 2. The waste is incinerated thoroughly under high temperature that is safely contained in the incinerator to ensure a safe and reliable operation.
  3. 3. The waste is incinerated in the first and second combustion chamber respectively. Dioxin and its precursor obtained in the first chamber are decomposed into small-molecule compounds when heated with high temperature in the 2nd chamber. The conditions in the 2nd chamber are not suitable for the production of Dioxin.
  4. 4. During the incinerating process under smoke control, there is minimal dust emission from both combustion chambers. The dust emitted by the smoke after disposal is only a fraction of the emission standard level.
  5. 5. Cost of running is low.

 

DC Dry Chemical Non-incinerator Series

The DC Dry Chemical Non-incinerator Series can be configured as either a mobile or a fixed-site unit., and both of them is a continuous feed RMW processor with an average volume of over 600 Kg per hour. This extremely high throughput is due to patented shredder technology and the proprietary UEEnviroTM dry chemical.
 
The facility performs sterilization and bio-safety disposal of the medical waste by adding UEEnviroTM dry chemical disinfector during the grinding process. The surfaces of the waste will be coated with the disinfector to eliminate the transductivity both chemically and physically. By breaking up the diaphragm and active coat protein, a fundamental change of the pH value will occur in the nucleic acid from the neutral 7.0 to 11.0-12.5. Once the cell walls are destroyed, the micro-organisms and viruses can be completely killed.
 
The DC Dry Chemical Non-incinerator Series renders Medical Waste unrecognizable and landfill-ready via the general waste stream. The environmental friendliness of the DC-8000 is further enhanced by the fact that the unit does not produce any air or wastewater emissions or other hazardous by-product.
 
The DC Dry Chemical Non-incinerator Series’ on-board computer monitors the pH value consecutively to ensure that the pH value remains between 11.0 and 12.5 after disposal and complies with the emission standards. All required information for permanent and regulatory records can be captured by the on-board computer. The DC fully complies with the safety standards implemented by SEPA and WHO. 

AC Autoclave Series
 
The AC Autoclave Series is developed with sophisticated technology that caters to the characteristics of the medical waste in China. The facility adopts a specific processing technology used in the P3 laboratory for sterilizer discharge to achieve thorough sterilization and prevent secondary pollution.
 
Technology Process
 
1. Pre-heating of medical waste
Once the feeding gate of the vapour jet chamber is closed, compressed and sealed, the high temperature vapour enters into the storage chamber to preheat the medical waste.
 
2. Repeated vacuum suction and pumping of high temperature vapour
Repeated vacuum suction and pumping of high temperature vapour is conducted simultaneously. Vacuum suction causes the tiny holes of the porous medical waste materials to remain in a status of negative pressure, helping the high pressure vapour penetrate through the materials while eliminating any untouched spots when the heat is conducted. Waste vapour is carried away together with the cooled water after heat transfer to achieve better heat conduction and the thorough destruction of plastic bags that wrap the medical waste.

3. Sterilization

The medical waste is sterilized under a high temperature of 134℃ at a pressure of 220KPa for a consecutive period of 45 minutes as required by national standards.

4. Drying
The drying process reduces the amount of cooling water produced out of the waste when the temperature is lowered and also to prepare for the grinding process at the next stage. Under consecutive vacuum suction, the vapour continuously enters the storage chamber to reach at an appropriate pressure to maintain a temperature required for drying. The medical waste contains less than 5% water after standard drying.
 
5. Unloading
Pressure is reduced before the gate opens to dispose the medical waste. The total volume of the waste will be reduced by 50% to 70% after it is dried and sterilized.
 
6. Secondary sterilization
The cooling water is collected by a collecting utensil and stored in the waste water storage chamber. Once the water reaches a certain level, the system will automatically initiate the secondary sterilization process to heat and sterilize the collected water. The water obtained from sterilization can be directly discharged through airtight pipes.
 
The tail gas filter adopts water-repellent and high temperature resistant mesoporous materials. The filter holes are no more than 0.2μm in diameter and can be used to filter bacteria and viruses. This filter is equipped with air admission and exhaust valves, a pressure meter and a water discharge valve. The design of the filter is created to correspond to filter flow and disposal capacity, achieving a filtering efficiency of over 99.999%
