Abstract

The invention relates to a static industrial air filter, belonging to the technical field of air filtering devices. The static industrial air filter comprises a shell and an axial fan, wherein the axial fan is arranged at the lower part of the shell, the shell sequentially comprises an air inlet, a first filter section, a second filter section and an air outlet from top to bottom, the first filtersection is internally provided with at least one layer of air filter element, and the second filter section is internally provided with an activated carbon filter layer. The processing process of theair filter element comprises the steps of (1) preparing materials; (2) crushing; (3) spinning; (4) weaving cloth; (5) forming a net; (6) making a needle fabric; (7) making a composite material; (8) attaching activated carbon; and (9) wrapping a layer of nonwoven cloth on the surface of the composite material attached with activated carbon, so as to prepare the air filter element. According to thestatic industrial air filter, aluminum oxide and zinc oxide are added in the air filter element, so that the static industrial air filter has good thermal resistance and corrosion resistance; the airfilter element can be adapted to various complex working conditions, so that the service life of the filter is prolonged.

Description

technical field [0001] The invention relates to a static industrial air filter, belonging to the technical field of air filtering devices. Background technique [0002] In petrochemical, electric power, metallurgy and other industries, due to some inherent characteristics of the industry, ventilation is required in many places, and fans are generally used for ventilation equipment. When working, the fan sucks air from the atmosphere. Since the air contains granular dust and impurities, these dust impurities will often flow into the downstream equipment of the piping system after being sucked by the fan, causing these equipment to block or destroy the normal operation of the equipment. Therefore, it is necessary to install an air filter capable of filtering dust and impurities at the inlet of the fan. [0003] At present, there are many types of air filters, but in the industrial production process, due to the frequent use and complicated working conditions, the practical li...
