FIELD: chemical industry; petrochemical industry;, metallurgical industry;, motor-car industry; other industries; devices for filtering gases and solid particles. ^ SUBSTANCE: the invention is pertaining to purification of liquids and gases from the solid particles and may be used in chemical, petrochemical, metallurgical, motor-car and other industries, which use the filters in the main production and the auxiliary production process, in the ecological processes of purification of the waste waters and the combustion gases, at the spillage of oil from the tank ships, the oil pipelines and the petroleum storages, and also for collection of the oil products from the water surface. Substance of the invention is that the filtering material been out of the synthetic filaments in the form of the tubular knitted fabric with disposed inside the knitted fabric the rubber crumbs of 1.2-2.6 mm size and the pebble gravel of 3.2-4.5 mm size. The tubular knitted fabric contains the filling threads, which diameter exceeds the size of the rubber crumbs in 0.5-1.2 times. At that the volumetric ratio between the rubber crumbs and the pebble gravel makes 3:1. The technical result of the invention is the improved quality of filtration in the process of purification of the liquids and gases, and the increased efficiency of purification of the shower flows and the industrial waste waters. ^ EFFECT: the invention ensures the improved quality of filtration in the process of purification of the liquids and gases, and the increased efficiency of purification of the shower flows and the industrial waste waters. ^ 3 ex, 1 tbl, 2 dwg |
