Which filter equipment for which application?
Which filter equipment for which application?Filtration equipment can be used in the following applications: clean rooms, photocopying equipment, anesthetic gases, laser surgery, heating, ventilation, and air conditioning systems, constant temperature rooms, computer rooms, etc.1、Plate filters, plate metal frame filters, and other equipment that cannot be reused, usually used in constant temperature and humidity air filtration systems; 2、Plate filters, bag filters, sub-high efficiency filters, activated carbon filters, etc., are usually used in ventilation systems of large buildings and public places; 3、Plate air filter, bag air filter, large air volume air filter, partitioned air filter, etc., usually used in the production of clean rooms with clean requirements; 4、Spraying top cotton, high-temperature glass fiber felt, high-temperature filter with partition, etc., suitable for spraying type of surface coating industry; 5、Plate type, bag type, large air volume, cylinder type air filter, generally used in the gas turbine industry; 6、a high-efficiency air outlet, FFU fan filtration unit and other air equipment can be used in the clean workshop. There is a wide range of types and sizes of filter equipment, how do I choose my equipment?There are several factors to consider:I. Types of filters and the accuracy of filtration1、Influencing factors: clarification, sterilization, concentration, separation;2、The content of the selection: microfiltration, ultrafiltration, nanofiltration; 3、Effect of sterilization: 0.3μm or 0.55μm; 4、Particle removal: 1-70μm; II, the choice of filter material1, According to the characteristics of the filtering fluid: gas or liquid, the composition of the fluid, chemical properties, temperature, etc;2, filtering liquid: try to choose hydrophilic filter material, such as polyethersulfone membrane, nylon membrane, etc; 3, filtering gas or strong acid and alkali solution: try to choose PTFE filter material. III, the choice of filter shell1, Factors affecting: filtering fluid, gas or liquid, the composition of the fluid, chemical properties, etc;2, the choice of content: generally can choose 304 or 316L stainless steel material, less or no thread. IV, the size of the filter1, the factors affecting: the flow of equipment, the viscosity of the liquid;2, the selection of the content: according to the effective differential pressure, the initial differential pressure, and the amount of filtration to determine; 3, the choice of items: whether the need for a pre-high efficiency filter; 4, the use of appropriate pre-high efficiency filters, can effectively extend the life of high-efficiency equipment and reduce costs. |
