filter device

Abstract

The invention discloses a filtering device. The filtering device includes: a central pipe assembly and at least one water inlet mesh, at least one pure water mesh and at least one page of membranes. The central pipe assembly includes at least two wastewater discharge conduits and As the central core element of the pure water conduit; one diaphragm is folded to form two overlapping layers of diaphragms. The overlapping diaphragm layer is set between the water inlet screen and the pure water screen. A part of the diaphragm is set between the wastewater discharge conduit and the pure water screen. In the cavity defined by the central core element, the other part of the diaphragm is laminated with the water inlet mesh and the pure water mesh to form a multi-layer membrane element arranged around the central core element; the water inlet mesh is not in direct contact with the wastewater discharge conduit. ;The pure water mesh is in contact with the central core component. According to the filtration device of the present invention, by arranging at least two wastewater discharge conduits and a central core element, a central tube assembly that facilitates rolling multi-layer membrane elements can be formed, so that multi-layer membrane elements can be used to achieve high water saving in the filtration device.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a filtering device. Background technique [0002] The concept of water saving is in line with the status quo of the industry and is the development trend of technology. At present, the recovery rate of large-flux reverse osmosis water purification equipment in related technologies is mainly 50%. When 1 ton of pure water is produced, it will produce 1 ton of waste water, waste water is not easy to be used, resulting in great waste. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the invention consists in proposing a filter device which can achieve a high water saving. [0004] According to the filter device of the present invention, comprising: a central pipe assembly, including at least two waste water discharge conduits and a central core element as a pu...
