Various Types Of Evaporator Structures

The evaporator is one of the most commonly used wastewater evaporators in the process industry. The evaporator is to pass the secondary steam vaporized by the previous effect evaporator into the heating chamber of the latter effect evaporator as the heating steam of the latter effect evaporator. Evaporation makes full use of the latent heat of vaporization of the secondary steam of each effect, and is a relatively energy-saving evaporation operation.

The evaporator is used in the liquid syrup concentration process of the corn chemical plant. The raw steam is passed into the chemical wastewater evaporator to heat the liquid syrup, and the water in the liquid syrup is heated and evaporated to achieve the purpose of concentration. There are also many reports on the research and application of multi-effect evaporation at home and abroad, but there are many researches on conventional simulation and optimization design based on the solution of multi-effect evaporation design problems, while the solution based on the operation of chemical wastewater evaporators Process simulation and operational optimization problems are rarely studied.

The structure and characteristics of the evaporator, and the working principle of the chemical wastewater evaporator and its application in chemical enterprises are introduced. In the wastewater concentration process, the tubular falling film evaporator is used. The wastewater flows in the tube and the steam condenses and releases heat in the shell side. .
