High-temperature high-efficiency filter

High-temperature high-efficiency filters play a vital role in the field of air purification needs for high-temperature environments, and the following information is detailed for you:
1. Product characteristics
Material composition
Outer frame: Generally, choose stainless steel material. In the case of low-temperature requirements, you can also use a galvanized frame.
Filter material: The main use of ultrafine glass fiber filter paper, this filter paper has the characteristics of high-temperature resistance and high filtration efficiency.
Baffle: The corrugated shape of aluminum foil accurately maintains the spacing between the pleats, thereby reducing resistance while fully using the filter material.
Sealant: There are two types of red silicone and ceramic glue. Red silicone can withstand the temperature of 250-280 ° C, ceramic glue can withstand the high temperature of 350-400 ° C.
Filtration efficiency
Its filtration efficiency covers multiple levels of H10-H14 to meet different filtration needs.
However, due to the influence of glue characteristics, the actual filtration efficiency may be reduced. For example, 250℃ H13 high-temperature high-efficiency filter, the actual efficiency is between H12-H13; 350-400 ℃ H13 high-temperature high-efficiency filter, the actual efficiency is between H11-H12.
Structural advantage
The diaphragm structure is adopted, and both sides of the filter material are folded at 180° to form a wedge fold layer. There are two indentations in the bending of the filter material, which can effectively prevent damage to the filter paper and extend the service life of the filter.
Second, application scenarios
Industrial production field
It is widely used in ultra-clean ovens, ultra-clean cleaning machines, high-temperature equipment in the chemical industry, and exhaust gas treatment systems in steam power plants to ensure the cleanliness of the production environment and the normal operation of equipment.
Medical and pharmaceutical field
In the pharmaceutical infusion production line, biopharmaceutical clean room laboratory, and other places, it is used for high-temperature sterilization and air purification to ensure the quality of drugs and the accuracy of experiments.
Electronic manufacturing field
It is suitable for clean workshops in electronics, semiconductors, chips, and other industries to provide a clean-air environment for the production of precision electronic components.
Food processing field
In the purified environment of food processing, such as baking ovens and other equipment, play a role in filtering the air and ensuring food hygiene.
3. Use attention points
Curing treatment
The new high-temperature resistant high-efficiency filter needs to wait for the glue to fully cure before use. Usually, the glue curing time is 3-7 days. If the customer is in urgent need of installation and use, it must be processed by the specific heating procedure, that is, slowly heating to different temperatures and maintaining for a period of time before stopping for cooling, so that the glue is fully cured, and the phenomenon of cracking, expansion and detachment from the outer frame during high-temperature use is avoided.
Temperature control
Use strictly in accordance with the temperature level of the filter. For example, a filter resistant to 250 ° C, its constant temperature should be controlled at about 260 ° C, and the instantaneous maximum temperature can reach 300 ° C. At the same time, it is necessary to avoid the filter running at the limit temperature for a long time, so as not to affect its performance and service life.
Installation specification
When installing, ensure a tight fit between the filter the sealing material, and the support frame to prevent leakage. For the need to withstand higher temperatures (above 250 ° C), galvanized frames or stainless steel frames must be selected to ensure the structural stability and high-temperature resistance of the filter.
maintenance
When the filter surface is found to be black, it indicates that it contains more dust, and the resistance increases at this time, and the non-woven fabric in the high-efficiency air filter needs to be removed in time for cleaning, or the replacement of a new filter.
It is recommended to check the nozzle wind speed regularly (generally 1-2 times a year), and if the wind speed does not meet the technical parameters, the filter should be replaced in time to ensure the filtration effect.
When replacing the filter, it should be noted that the model specifications of the new filter should be consistent with the original filter, and careful operation should be carried out to avoid hitting the frame and damaging the filter paper. At the same time, pay attention to the arrow sign on the filter and make sure that the arrow points in the direction of the airflow.
After replacing the new filter, it must be confirmed that there is no leakage between the filter and the sealing material and the support frame to ensure the tightness and filtration effect of the filtration system. In addition, regular electrical line checks should be carried out to ensure the normal operation of the equipment.
