High efficient Thermal Vapor Recompression (TVR) Evaporators in food, pharmaceutical, chemical, bioengineering
Principle
A part of the vapour steam is compressed to a higher pressure and temperature level by a steam jet pump with steam, so that it can be used as a heating medium.
Process description
The solution is preheated with condensate and enters the evaporation circuit. Here it mixes with the circulated solution and is warmed up in heater H. In the evaporator V, solvent (water) evaporates while cooling the solution to the boiling temperature. The resulting vapour steam is compressed to a higher pressure and temperature level by the steam jet pump with the help of steam, so that it can be used as a heating medium for heating the circulated solution. The excess vapour is condensed. If salt shall be crystallized in the plant, further evaporation concentrates the solution to such an extent that crystals are formed. If desired, the crystals in the suspension can then be separated from the solution and dried.
Thermo compressors
Thermo compressors are designed to recycle heat energy by capturing and recompressing waste steam for use elsewhere.
Thermo compressors, like ejectors, have no moving parts. The mechanical design consists of a steam chest, nozzle holder, nozzles, and diffuser.
The thermo compressor uses high pressure steam, as a motive fluid, which enters the steam chest and expands through the nozzle.
The high-velocity steam then entrains the waste steam, into a mixing chamber where the fluids are combined.
The mixed fluids are then recompressed to an immediate pressure through the diffuser, which acts as a nozzle in reverse, reconverting velocity energy to pressure energy.
Thermo compressors are designed for applications in the food, petroleum, chemical, power, and paper industries. Thermal recompression is typically applied in the dairy and juice industries to recapture and reuse steam from evaporators during the concentration process.
All thermo compressors are custom designed and performance tested to meet our client’s exacting specifications.
