Positive pressure sterillization filtration system introduction:
Sterillization air filtration technology has been used a lot in the developed countries. It has been the production of sterile air filters in industrial scale in large numbers. There are many patents relating to the manufacture of equipment to ensure sterile air for the relevant sectors. The annual product from entering the market more and more in terms of quantity as well as kind, especially in the years of the late 20th century when the development of integration needs of the pharmaceutical industry must strive to GMP, GLP , and GSP, the fishery must meet HACCP standards, the biotechnology industry to ensure fast plants and animals for agricultural development, health department hospital to implement anti-infective program for operating rooms... Positive pressure stirillization filtration system designed including parts and equipment follows: 1.Air filtration stirilization equipment - Pretreatment by UV light:
To increase the efficiency of sterilizing, before passing through the HEPA filter, the air will be pre-sterilized by UV light
2. Positive pressure generator:
This part work to create a positive pressure in the surgery room and corridor by creating pressure devices. The positive pressure generator is designed by high-pressure squirrel cage fan with large capacity, high durability. In addition to preventing bacterial penetration from the outside (especially when entering or goingout the surgical area) positive pressure generator also contributes to limiting oxygen deficiency in the long time lasted operation with big number of participants 3. Micro air filter Hepa:
These filters can retain 99.9% of particles 0.3 microns. They completely can use to pasteurize air.
Filters are manufactured by a variety of methods such as Zic-zac fold-style corrugated with height of every paper segment from 80 to 100mm, used coffee filter pater as insert material against falling between the zone. This technology has high capacity, high pressure bearing, can blow directly without incurring insertion and disproportion effect of paper zones. II. Positive pressure sterillization filtration system operating principle
1. Principle diagram:
a. Principle diagram of air stirillization processing:
 b. Principle diagram of air re-treatment:
 2. Technology description:
The entire treatment system is placed on laphong, re-treatment processor and intake air part is placed at a convenient position with beam to get fresh air. Air is drawn through the primary filter to remove larger dust particles. Next, it is handled by short-wavelength UV light (254nm) to kill the bacteria.
Is continuously create positive suction pressure and push through the treatment system by Hepa membrane. 0.3mm." j="HEPA filter capable of removing 99.99% of bacteria and the size of> 0.3mm. " g="Màng lọc hepa có khả năng loại bỏ 99.99% các vi khuẩn và các chất có kích thước >0.3mm.">HEPA filter capable of removing 99.99% of bacteria and the size of> 0.3mm. Also at this air sterilizer 1 again by UV, ensure sterile air completely before entering the operating room. Air flow is adjusted on the device capacity. Each room has two gas treatment systems are located on the ceiling. Next, the gas is put into a sterile air supply system pressure positive, use Hepa membrane and the pressure. Air from the air conditioning is also treated with UV light to ensure non-contaminated air. The air in the room will be handled by the secondary filter and gas sterilized with UV light before transmission out. Ensure no pollution to the environment and the fight against infectious pathogens.  |
