Liquid Jet Eductors use the kinetic energy of a liquid to entrain another liquid. They completely mix the two, then discharge the mixture against a counter pressure. They are used in large numbers throughout industry for pumping and mixing operations.
Applications are so vast, it is impossible to note all of them.
General uses include:
Some of the typical applications can be seen below:
The Hopper Eductor is a hopper equipped jet ejector. It is designed to entrain and mix granular solids or slurries with liquid, and transfer it to a desired location.
Originally developed to mix drilling mud for oil industry applications, these devices have proved to be so effective and versatile that they are being applied in increasing numbers in diverse industries including:
Hopper Eductors are also used for ejecting sludge's from tank bottoms, for pumping sand from filter beds and for washing and conveying granular materials.
Typical materials handled can be:
Steam jet Ejectors are based on the ejector-venturi principal and operate by passing motive steam through an expanding nozzle. The nozzle provides a controlled expansion of the motive steam to convert pressure in to velocity. This creates a vacuum within the body chamber to draw in and entrain gases or vapours.
Primary advantages over other vacuum pumps can be seen below:
Steam Desuperheater have been designed to reduce the temperature of super heated steam to produce lower operating temperatures.
Most of the installations fall into these typical installations.
Steam Jet Heaters mix steam uniformly with a cold liquid. Tthe steam is fully condensed in to the liquid being heated which allows the liquid to reach within 5 degrees Celsius. The jet action within the heater, produces turbulence to keep steam bubbles to a minimum for maximum heat transfer. It would also reduce noise and steam at high operating temperatures.
Steam Jet Heaters are available in two groups. Firstly we have Pipeline Heaters which are installed in pipe lines for instantly raising a fluids temperature. Secondly, Tank Heaters are installed at the bottom of the tanks to provide gradual heating and tank agitation.
The use of wet scrubbers, to control air pollution, has gained wide acceptance through out industry. Gas scrubbers can be very effective at removing the following:
Contaminants are removed by impaction with a high velocity spray. Where as gases and odours are eliminated through absorption, or chemical reaction between gases and scrubbing liquid.
In addition to being highly effective air pollution control devices, wet scrubbers like these are also used in process operations where:
