Cavitation Reactors

The combination of and technical developments in the field of acoustics, hydrodynamics and chemical kinetics result in new promising devices in the technology market. One of them is the cavitation reactor capable of producing suspensions, emulsions and intensifying chemical processes in solutions. It can either be used separately (in laboratory equipment) or as a part of industrial production lines. In today’s market, there are two types of cavitation reactors: ultrasonic cavitation reactors and hydrodynamic cavitation reactors. The latter are more popular  due to simplicity of design, reliability and affordability.

A modern cavitation reactor performs continuous dispersion (grinding of the solid component), homogenization (additional grinding of one fraction and its homogeneous distribution in a liquid medium), disintegration (breaking of complex substances into constituent parts) and deagglomeration (breaking up of particle aggregates). It helps to commercially receive emulsion resistant to stratification.

The principle of operation of any cavitation reactor is the initiation of cavitation processes in a solution pumped through the reactor. The drop of local pressure with a slowing current (hydrodynamic cavitation) or a powerful acoustic wave (acoustic cavitation) cause cavitation bubbles to appear. The bubbles rapidly collapse, generating shock waves. In the hydrodynamic cavitation reactor the process occurs when the mixture passes through special nozzles. The geometry of the nozzles may vary, controlling the fluid flow, acheiving the necessary rheological properties and the desired result.

Apart from geometry, the performance of a cavitation reactor depends on the operating pressure in the reactor and the temperature of the fluid (emulsion slurry). For example, by increasing the pressure of the pumped fluid from 5 to 15 bar, the cavitation processes occurs at least ten times more intensively. It is worth noting that the maximum intensity of the cavitation processes is achieved not only by the increase of pressure but also by raising the temperature. Experiments show that optimum cavitation effect occurs upon heating the liquid to 65% of its boiling point

In operation, the inner surface of the mixing chamber and the nozzle of the  cavitation reactor undergo tremendous stress. GlobeCore make their reactors of heavy-duty, impact and abrasion resistant materials. If the liquid is chemically active, the cavitation reactor is made of chemically resistant materials.

GlobeCore cavitation reactors are used for continuous biodiesel production, making the material more homogeneous. Under the influence of cavitation shocks, the complex molecular bonds are broken, and the particle size is reduced to 1-8 micron. This dramatically increases the surface of the particles of biological material coated with bacteria and, as a result, intensifies biogas production by 30-50%

GlobeCore Cavitation reactors are versatile, compact and reliable, they have the highest quality at the best price, putting GlobeCore equipment in the leading position in the global market.
