Rubber foam intake conical air filter
Introduction of rubber foam intake conical air filter
The rubber foam intake conical air filter takes polyethylene or polyester foam plastic as the core filter layer, forms a three-dimensional connected pore structure through chemical treatment, and realizes efficient inertial interception and diffusion filtration. Its conical design is optimized through fluid mechanics to evenly distribute the intake along the curved surface, reduce local velocity differences, and thus reduce resistance losses. The typical structure adopts galvanized steel plate skeleton support, combined with low hardness closed cell rubber sealing rings, to ensure zero leakage under a working pressure of 0.6MPa. The pore size of the filter material is usually controlled within the range of 200-300 μ m, which can capture particles larger than 0.5 μ m and maintain low resistance characteristics of 0.3-0.5kPa. Some high-end models use flame-retardant nanofiber composite filter paper, combined with super strong adhesive to fix the pleated structure, which increases the filtration area by 40% compared to traditional filter materials, and extends the service life to more than 2 years while maintaining high dust holding capacity.
Characteristics of rubber foam intake conical air filter
This filter has four core advantages: firstly, it has strong weather resistance and can work stably in a wide temperature range of -80 ℃ to+480 ℃, adapting to extreme environments such as the Northwest Loess Plateau; Secondly, it is resistant to chemical corrosion. The 304/316L stainless steel filter can withstand strong corrosive media such as concentrated sulfuric acid and caustic soda; Thirdly, self-cleaning and high-efficiency. When using pulse back blowing technology, the rigid structure of the filter material ensures that wrinkles do not collapse, and the dust cleaning efficiency reaches 98%; Fourthly, maintenance is convenient, modular design supports online replacement, and the maintenance time for a single shutdown is reduced to less than 15 minutes. Actual test data shows that in a large chemical enterprise, the filter reduces the growth rate of system pressure difference by 60% and reduces annual maintenance costs by 42000 yuan. Its flame retardant performance has passed UL94 V-0 certification, which can prevent flame spread in case of sudden fire and ensure equipment safety.
Usage scenario of rubber foam intake conical air filter
This filter is widely used in three scenarios: in the energy field, as the first level pre filter of the gas turbine intake system, it can intercept 99% of sand and dust particles, protecting the GE 9HA gas turbine worth billions of yuan from wear and tear; In the pharmaceutical industry, 316L stainless steel material meets GMP standards and is used for fresh air filtration in sterile workshops to ensure that the environment for drug preparation meets ISO 5 cleanliness level; In the field of food processing, combined with HEPA terminal filtration, a cascade purification system is formed to control the bacterial content in the air of the beer filling workshop below 10CFU/m ³. Especially in the reconstruction project of an air compression station in a coal mine in northwest China, after the conical foam filter was used, the equipment failure rate dropped from three times a month to zero, and the annual spare parts cost was saved by 280000 yuan, verifying its reliability under adverse conditions.
