Industrial parallel water inlet three-stage disc-type filter

Abstract

The invention relates to an industrial parallel water inlet three-stage disc-type filter, and belongs to the field of water treatment equipment. The industrial parallel water inlet three-stage disc-type filter comprises an outer tube; a raw water inlet is formed in the upper end of the outer tube, and a sewage outlet and a pure water outlet are formed in the lower end of the outer tube; a screw rod is arranged in the outer tube and sequentially provided with a first-stage filter element, a second-stage filter element and a third-stage filter element from top to bottom, wherein the first-stagefilter element, the second-stage filter element and the third-stage filter element communicate; and partition flow-guiding discs are arranged between the first-stage filter element and the second-stage filter element as well as between the second-stage filter element and the third-stage filter element correspondingly. The industrial parallel water inlet three-stage disc-type filter has the beneficial effects that the water production efficiency is high, the water resource is saved, electric energy consumption and the production cost are lowered, three-stage series filtering is adopted, the excess pressure of the previous stage can be utilized sufficiently, the water utilization rate is high, the requirement for the water quality of raw water is not high, and pretreatment is not needed.

Description

technical field [0001] The invention relates to an industrial parallel water inlet three-stage disc filter, which belongs to the field of water treatment equipment. Background technique [0002] Along with the general improvement of society's awareness of sanitary water, reverse osmosis water purifiers for filtering water have widely entered various places where people live and work. In order to strengthen the management of water purifiers, my country implemented the national standard GB34914-2017 "Reverse Osmosis Water Purifier Water Efficiency Limits and Water Efficiency Grades" on November 1, 2018. This standard stipulates the water efficiency detection and calculation method of reverse osmosis water purifiers. The standard stipulates: "After being purified by the reverse osmosis system of the water purifier, the ratio of the total purified water to the total influent water is the purified water production rate. , referred to as water effect". The water efficiency level...
