Construction of hydro cyclone

Thesis Overview

<p> </p><p><strong>INTRODUCTION</strong></p><p>Since 1772 Ac, the ancient Greek’s and the Roman Empire has successfully been equipment for separation to carry out separation operation. In the past, there are different separation apparatus invented either for the purpose of size reduction or for size separation process such as decapitation and filtration. But later, a way of separating liquid from liquid by distillation process was introduced, but the mystery of separating dust, steam of gas and liquid remain not until recently, when it was broken by the invention of an apparatus called the electrostatic precipitator and the cyclone.</p><p>A cyclone, which is a mechanical separating equipment, is concerned with the separation of particulate and could be defined as a type of centrifugal equipment for separating dust or mist from gasses. The separation of a cyclone takes effect due to the strong centrifugal acceleration that act radially. The separation depends on periodically size and also on particles density, therefore, cyclone may be used to effect separation on the basis of particle size or density or even both.</p><p>If the apparatus is the hydrocyclone, the liquid used in this apparatus is usually water and the viscosity (m) is much higher than that of the gas.</p><p>The uncounted fluid resistance is greater in hydrocyclone than in ordinary cyclone. In hydro-cyclone which are solid-liquid separator, the slurry is pumped in tan gentially near the top coarse or heavy solid are thrown out to the apex and the same or higher solid are removed from the center of the vortex at the top.</p><p>Generally, hydrocyclone have pared way needed, often for processes that makes use of pure (filtered) air as their raw material is needed. For instance, in electronic and pharmaceutical industries where dust particles are to be removed may range from 10 to more than 2,000mu, in size. Moreover, in an evaporator, it is frequently necessary to estimate droplets, which become entrained in the vapour and in a plant involving fluidized solids.</p><p>OBJECTIVE OF THE PROJECT</p><p>The objective of this project is to construct a hydrocyclone that can be used in small scale industry for the size separation processes. The constructed hydrocyclone can also be used industrially for product quality improvement, as in an cleaning in pharmaceutical products and photographic film. A suitable choice of material of construction was made in order to enhance the versatility of its application’s.</p> <br><p></p>
