Scraped Stainless Steel Surface Falling Film Evaporator

Product Description

Product Description

Rising film evaporator is also know as vertical long tube evaporator, rising tube evaporator.
Rising film evaporators are suitable for dilute solutions with low concentration and heat-sensitive materials.
The solution is preheated to the boiling point, added from the bottom of the heating chamber, and strongly vaporized in the heating tube. The generated vapor drives the liquid to rise in the form of a film along the pipe wall. The liquid film continues to evaporate as it rises. The solution can reach the required concentration through the heating tube.

Application

Rising film evaporators are mainly used for concentration, distillation and recovery of organic solvents in bioengineering, pharmaceuticals, beverages, petroleum, fine chemicals, water treatment and other industries.
Rising film evaporators are widely used in sewage treatment, polymer production, food production, thermal desalination, pharmaceutical and solvent recovery industries; Rising film evaporators are mainly used as reboilers, preconcentrators, flashers or preheaters of distillation columns.

Structure Introduction

The rising film evaporator is composed of buffer tank, preheater, heater, separation chamber, gas-liquid separator, condenser, cooler and receiving tank.

Working Principle

Rising film evaporator adopts decompression concentration technology, which greatly reduces energy consumption and operating cost. 
The raw material is preheated to the boiling point or close to the boiling point, and is introduced into the tube from the bottom of the heating chamber. The high-speed rising secondary steam drives the solution to flow in the form of a film along the wall and evaporates; the required concentration is reached at the top of the heating chamber, and the solution is discharged from the bottom of the separator.
The vapor liquid separator separates the liquid carried by the steam, and the unvaporized liquid returns to the concentrator. The condenser liquefies the gas to achieve solvent recovery. The cooler cools the liquefied solvent to achieve full solvent recovery. The receiving tank collects and stores the liquefied solvent.
