ABSTRACT

The hydrocyclone is a separating device used for the separation of dust particles from air, which has no moving component parts. This mechanism can also be defined as a system of winds circulating about a center of relatively low barometric pressure and on the earths surface, blowing inward in spiral form.

This project is constructed for the separation of liquid – liquid and solid – liquid mixture, like air and dust mixture, dust and liquid drop. This equipment is constructed to separate dust air mixture input of about 25m ³/h.

The equipment was constructed with flat sheet metal plate of a desired standard. The dimensioned and for truncated parts were coupled and welded in other to fasten the parts together. The material used in this construction is mild sheet. This material was selected to avoid the effect of rust of material due to contact of the separating item or material with the walls of metal sheet.

In considering the rating of this instrument, it is capable of sparing a gas-dust mixture of about 70% pure compared to the one used in commercial industries. That has the offering of product at around 90% pure. The total material cost of this equipment is ten thousand naira ( N 10,000).

The effect of hydrocyclone had been of much help especially in the pharmaceutical and photographic industries in the process of particle size separation. It is use to separate a mixture of particle size within the range of 4 and 95 m. The moving or relative speed for this model during separation is 4mls.
