Description

Variable hydrocyclone for treating contaminated water with multiple inlets and vortex formation induction device

Various embodiments relate to a variable hydrocyclone for treating contaminated water having multiple inlets and a vortex inducing device.

In the event of a marine pollution accident, an emergency response plan is needed to prevent further contamination through prompt recovery of spilled oil. Oil absorbents and dispersants are used as spill control methods. In the case of oil sorbent, a method widely used as a preventive material for coastal pollution accidents is to distribute the sorbent to the sea and recover the oil when it is adsorbed. This has limitations in that a lot of manpower is required for distribution and recovery, and it is difficult to recycle the oil, and secondary environmental pollution is followed by the disposal of the oil-absorbed adsorbent. In the case of a dispersant, a method of making oil in a form that is easy to decompose by microorganisms has recently been limited in use due to controversy over the effect on the environment.

The occurrence of green and red tides due to eutrophication of rivers, lakes and seawater in the high-temperature dry summer each year causes great social losses such as difficulties in supplying drinking water and mortality of farmed fish and shellfish. A direct way to prevent the large-scale proliferation of blue-green algae causing algae in rivers and lakes and to purify contaminated water is to discharge dams or weirs, but there are limitations depending on the amount of precipitation.

As a way to reduce the red tide caused by the large-scale proliferation of diflagellates in the sea, a method of sedimenting to the seabed using ocher is used, but it is not a fundamental solution, and there is a limit to its application to the sea with a wide range of treatment. .

In the case of a hydrocyclone for water treatment, it is a technology that separates a mixture by the difference in specific gravity of the mixture by forming a vortex of water in which two or more materials are mixed. Since the inlet of the hydrocyclone must be arranged so that mixed water can flow in the tangential direction of the cylinder to form a vortex, the treatment capacity is considerably limited. In addition, since the separation efficiency is determined according to the characteristics of the mixture to be treated, such as specific gravity, particle size, etc., and the shape of the hydrocyclone, there is a problem in that the design of the hydrocyclone must be changed according to the application.

Various embodiments provide a variable hydrocyclone for treating contaminated water that can respond to a wider range of separation of mixed water.

Various embodiments provide a variable hydrocyclone for treating contaminated water having multiple inlets and a vortex inducing device.

According to various embodiments, the first outlet may be a second outlet through which the separated first material is discharged from the housing, and the second end portion may be a second outlet through which the separated second material is discharged from the housing.

According to various embodiments, since the variable hydrocyclone induces a vortex with respect to the introduced mixture using the vortex forming induction device, a plurality of inlets may be provided without limiting the location of the inlet of the variable hydrocyclone. Accordingly, the treatment capacity for the mixture in the variable hydrocyclone can be increased. In addition, as the variable hydrocyclone is implemented to be assembled and detachable, the size or number of inlets or the shape of the vortex, such as speed and angle, can be adjusted according to the mixture to be treated. Accordingly, the variable hydrocyclone can respond to the separation of a wider range of mixtures.
