Evaporator is used for concentrating waste liquid by using steam etc. as heat source and then volume of waste liquid is reduced.
We have some types of evaporator such as single, multi-effect of unit structure, multi-effect with external heating, etc. and we design evaporator by client's request and physical properties of waste liquid.
Single type evaporator
Single type evaportor + steam compressor
Compress and re-use generated steam.
The amount of steam is reduced to less than 1/3 as compared with a single
Double-effect evaporator + steam compressor
Waste liquid 10 ton/h is concentrated 10 times.
The consuptiovs is charged depending on waste liquid conditions.
|Type||Steam consumption||Power consumption|
|Single evaporator||9 ton/h||11 kW|
|Triple-effect evaporator||3 ton/h||20 kW|
|Single evaporator + steam compressor||0 ton/h||310 kW|
|Double-effect vaporizer + steam compressor||0 ton/h||190 kW|
