Dual-swirl water purifier

Abstract

The invention belongs to the field of water treatment equipment and discloses a dual-swirl water purifier, which can perform tertiary sewage treatment without extra power. The dual-swirl water purifier is formed by sleeving three layers of pipe sleeves with different diameters, wherein the upper part of an outer sleeve is provided with a water inlet which is communicated with a primary swirl cavity; a sewage collecting and settling area and a sewage outlet are formed on the lower part in the outer sleeve; a water inlet oblique cut is formed on the surface of a middle section of a middle sleeve along the tangential direction; the outer surface is wound with spiral swirl vanes and spiral swirl lower vanes; gaps are reserved between the vanes and the outer sleeve; a gap is not reserved between the lower vanes and the outer sleeve; and a filtering net is arranged on an outer surface of an inner meshed pipe framework and is communicated with a purified water outlet. Three filtering and purifying functions, namely primary filtering, middle precision filtering and final filtering are realized, and the invention has the characteristics that the water purifier is small in size, compact in structure and high in sewage treatment amount, a recycling ratio of water is improved, and the water resources are saved.

Description

technical field [0001] The invention belongs to the field of water treatment equipment, namely a double swirl flow water purifier, which can carry out three-stage sewage treatment without external power. Outer casing and middle casing Background technique [0002] In the prior art, the application of cyclone water purifier (filter device) is on the rise both at home and abroad. It is a preliminary filter device that does not require external power, and is widely used in fields such as industrial water, agricultural water and domestic water. It includes an outer casing and an inner casing, which are made of two layers of pipes with different diameters. There is a water inlet on the outer casing, a sewage outlet on the bottom, and a water outlet on the upper part of the inner casing. The principle is The principle of gravity stratification of rotating fluid is used to realize the preliminary purification treatment of sewage. However, most of the above-mentioned cyclone filte...

Problems solved by technology

However, most of the above-mentioned cyclone filter devices are simple in structure, and can only perform preliminary graded filtration and purification treatment of sewage. In large-scale industrial sewage purification treatment systems, they generally only play the role of primary filtration equipment, and systems or equipment with higher water quality requirements are generally used. , it is difficult to achieve the required water quality only by using a cyclone filter. Generally, a higher level or continuous filtration and purification treatment device is placed behind it, resulting in a complex structure.
