Sterilizing filter sterilizing filter sterilizing filter sterilizing filte

  Sterilizing filter sterilizing filter sterilizing filter sterilizing filter
 
【1】 The sterilizing filter mainly adopts large specific surface area, and the filtering accuracy is 0
22-mu; The microfiltration filter element above M is mainly used to prevent impurities, harmful bacteria and microorganisms in the air from entering the tank, production line and sterile room, causing changes in water quality, products and the environment of sterile room, so as to meet the process needs of food, biochemistry, beverage, beer, medicine, electronics and other industries
Filter element material
The main filter materials commonly used for filters are roughly as follows:
Mixed cellulose ester
It is often used to make circular single plate filter membrane for fine filtration of liquid and gas;
polypropylene
It is made into a folding type, which is commonly used in cylindrical filters
It has a large pore diameter and is hydrophilic
It is a coarse filter material;
Polyvinylidene fluoride
It is a fine filtration material, which is heat-resistant and chemically stable, and has good steam sterilization resistance
It can be made into hydrophilic filter membrane, which is widely used in the filtration of sterile preparation water and injection water in pharmaceutical industry;
Polyethersulfone
It is made into a folding type, which is commonly used in cylindrical filter
It has good temperature resistance and hydrolysis resistance
It is a hydrophilic material, which is used for fine filtration of high-precision solution;
nylon
It is made into a folding type, which is commonly used in cylindrical filter, hydrophilic material and fine filtration of liquid;
teflon
It is made into a folding type, which is commonly used in cylindrical filters and hydrophobic materials
It is a widely used material with heat resistance and chemical stability
It is often used for fine filtration of water, inorganic solvents and air

In addition, filter materials can be divided into hydrophilic (water wettable) and hydrophobic (water non wettable) according to their relationship with water

Hydrophilic filter materials are mainly used in the filtration and sterilization filtration of water or water / organic solution mixture; Hydrophobic filter material is intercepted or & ldquo; Guide & rdquo; Entering the filter membrane is mainly used in solvent, acid, alkali and chemical filtration, tank / equipment respirator, process gas, fermentation inlet / exhaust filtration
characteristic
(1) Generally, the sterilizing filter adopts cross suspension type with horizontal inlet and outlet
The multi-core filter can be designed as floor type

(2) Some applications are divided into pre filter and fine filter according to actual needs

(3) Air flow direction: pass through the filter element from the outside to the inside

(4) The compressed air entering the sterilization filter must first pass through at least three-stage precision filter and dryer
For oil, water and dust removal, the concentration of oil mist shall be ≤ 0
01ppm, otherwise it will affect the service life of the sterilization filter element and fail to achieve the expected sterilization effect

(5) Sterilize regularly, once or twice a week or every month for 30 minutes according to the actual use 1μ Clean saturated steam sterilization with filtration accuracy
Steam temperature & lt; 140 ℃, steam pressure & lt; 0
3MPa。 The valve opens and closes slowly

(6) When used as a respirator for tanks and equipment, its function is mainly to connect the atmosphere, prevent negative pressure inside the equipment and isolate pollution sources in the air
The function of filtration is small, so there is basically no requirement for filtration
General technical parameters
