High Evaporation Speed Stainless Steel Falling Film Evaporator

High Evaporation Speed Stainless Steel Falling Film Evaporator

Falling Film Evaporator Description

The falling film evaporator is suitable for evaporation and concentration of the foaming material, and the liquid is evaporated in the heating tube to form a vapor-liquid separation. At the bottom of the body, most of the materials are pumped away, only a small amount of liquid and all the secondary steam enters the separator for separation. The entire process does not have much impact, in order to avoid the formation of bubbles.

Falling Film Evaporator Parameter

Falling Film Evaporator Application

The falling film evaporator is widely used in the evaporation and concentration of water or organic solvent solutions in the pharmaceutical, food, chemical, light industry and other industries, and can be widely used in the waste treatment of the above industries. The falling film evaporator is especially suitable for heat sensitive materials. The whole equipment is continuously operated under vacuum and low temperature conditions, with high evaporation capacity, energy saving, low operating cost, and can ensure the material is invariable during evaporation.

Falling Film Evaporator Principle

The working principle of falling film evaporators can be described as follows. The materials are added from the upper part of the heating tube. They are evenly distributed into each falling film pipe through the distributor, and flow down the wall of the pipe in the state of a liquid film. Under the action of gravity and the secondary steam flow, the materials get evaporated while flowing down. At the bottom of the falling film tube, the materials and secondary steam are basically separated, and they reach the separation chamber to achieve complete separation.

FAQ

1. Why is single-effect falling film evaporator commonly used for ethanol recovery?
Ethanol has low heat content and is volatile, so it is not suitable for multi-effect falling film evaporator.

2. What is the feed temperature of the single-effect falling film when recovering ethanol?
It is recommended to be above 20 °C, if the low temperature material liquid can add a preheating device before the cloth.

3. How much is the steam pressure in the heating chamber controlled?
The steam pressure is controlled within 0.2MPa, and the temperature is within 130 °C.

4. How to control the steam temperature?
By adjusting the steam pressure to adjust the steam temperature, the temperature changes with the pressure.

5. What material is the single effect falling film evaporator, can it be made of 316 material?
Hygienic grade 304 material. According to customer needs can be made of 316 material.

6. Is the single-effect falling film evaporator controlled automatically or manually?
Manual control. According to customer needs can make automatic control system.

7. Can 200L single effect falling film evaporator be sent by air?
After special packaging design, it can be sent by air.
