Description

Technical Field

[0001] The utility model relates to the technical field of filter bags, in particular to a bag-type oil removal filter. Background Art

[0002] As a filter element, the filter bag is a key link in the filtration process. The quality of the filter bag largely determines the filtration effect. The filter bag is widely used in industries such as chemical industry, petrochemical products, automobiles, paint and varnish, electronics, pharmaceuticals, resins, plastics, inks and coatings, beverages and foods, water treatment, and metal processing.

[0003] The oil removal filter bag is used to filter the oil in gas or liquid, so that the oil adheres to the bag body. When filtering oily sewage, most of the time, the oily sewage is poured into the bag body. The non-oil liquid in the oily sewage passes through the gaps of the filter bag, and the oil will adhere to the filter bag. Since the density of many non-oil liquids is greater than that of oil, the oil will float on the liquid surface. During filtration, the oil will adhere to the side wall of the oil removal filter bag, blocking the side wall of the oil removal filter bag, while there is only less oil on the bottom of the oil removal filter bag, resulting in low utilization rate of the oil removal filter bag and low overall filtration efficiency, which needs to be improved. Content of the Utility Model
