Factor selection for thin film evaporator

2018-05-19

Thin film evaporator is a kind of chemical equipment often used in chemical production. Evaporation crystallization equipment is used in wastewater treatment, pharmaceutical food concentration and other processes. The different evaporating equipment is suitable for different materials, so today we will familiarize you with the thin film evaporator.

Thin film evaporator is a new type of high efficiency evaporator, which is forced into film by rotating wiper, high speed flow, high heat transfer efficiency and short stay time (about 10~50 seconds).

The film evaporator is a type of evaporator, which is characterized by the heat transfer and evaporation of the material liquid along the wall of the heated tube. It has the advantages of high heat transfer efficiency, fast evaporation speed and short residence time, so it is especially suitable for the evaporation of heat sensitive material. In the selection of thin film evaporator, various factors must be considered.

1, production capacity and operating parameters: including handling capacity, inlet and outlet concentration, temperature, annual operating hours and so on;

2, product characteristics: including heat sensitivity, viscosity and fluidity (at operating temperature), foaming property, solid content, crystallization and polymerization tendency;

3, operating medium: such as water vapor (pressure), cooling water (temperature), cleaning fluid (solvent), etc.

4. Material selection and surface polishing requirements.

5, site conditions: such as space, climate (outdoor), energy and product convergence, work platform, etc.
