Gas heater / heat exchanger is an apparatus (device) in which the heat is delivered (performed transition) from one medium to another. They can be made so that the media are touching each other and are separated by a partition, the pipe wall, etc. that prevent their direct contact.
Heat exchange surface is derived from the tube so these heat exchangers are called tubular heat exchangers.
Depending on which process is primary, i.e. whether we want the main medium heated or cooled, heat exchangers are divided into heaters and refrigerators.
The materials used for the production of heat exchangers are usually steel. Can be non alloyed, low alloyed, high alloyed steel and cast steel. Pipes for producing heat exchanger is made of aluminum and its alloys, copper and its alloys as well as carbon, low alloy and high alloy steel. Gas heater / heat exchanger is protected with anti-corrosive influence of surface corrosion, aggressive influence of the atmosphere, condensation, etc.
Measuring of industrial gases frequently requests a
precise pressure regulation for the purpose of dosage
UNIS FAGAS has two kinds of pressure regulators,
1893 B and 1853 B in its production programme.
These regulators enable economical and precise regulation of pressure in various of applications, as well as
protection od consumers from overpressure and under pressure in the installation.
Hydro cyclone units
are applied in order to separate coarse and fine solid particles from liquids . These type of separators are particularly capable of separating sand, starch, and other finely distributed materials. With hydro cyclones it is possible to separate fine particles online during the process.
Hydro cyclone units are used to separate, classify, and to thicken suspensions. Also, these units are used to purify ores and minerals. Also, in fibre technique and paper industry they are applied in purification processes to separate dirt. Hydro cyclones are frequently run in parallel mode.
The lay out and design of hydro cyclones are performed empirically similar to the duct cyclones. In the lower flow region of a hydro cyclone an air swirl forms during the separation process, which is not substantially influencing the cyclone flow. Because of the large dimension of the cyclone, wall friction has much more influence on the flow.
The gas cyclone
belongs to the mostly applied technical separators, because it has applicationwise some fundamental advantages. One of them is certainly the fact that its construction does not show any movable components.
For the large variety of different kinds of dispersed (particulate) phases (for example dust particles, metal chips, wooden waste, liquid droplets) and different gas conditions (pressure, temperature) the lay out and computation of a cyclone is still a complex task.
Suvis has specialised in the development and lay out of cyclone separators and can offer professional solutions and consulting in the area of gas cyclones. Many years of experience gained through numerous cyclone development projects results in optimal solutions for our customers.
A cyclone separator applies centrifugal forces and represents an effective apparatus for separating gas, liquid or solid particles from a continuous phase in chemical, process or environmental engineering.
The Suvis GmbH also deals with
the application of modern numerical methods for the lay out and optimisation of various separator types like cyclones. A typical application of these computation methods is the computer aided investigation of particle separation from gases in cyclones. The prediction of the separation efficiency allows the reliable optimisation of conventional cyclones and the development of completely novel high efficiency cyclones. With that, very often expensive filter units, wet cleaner, or costly electro filters can be replaced or completed.
When applying numerical methods (CFD simulations) to cyclones one encounters the problem of strong curvature of the stream lines because of the resulting strong swirl flow and the abrupt change of flow direction towards the outlet tube. This means that the assumption of isotropic turbulence is not useful anymore.
