Distiller Ethanol Thermal Vapor Recompression Evaporator
|
Industry Distiller Ethanol TVR Multi effect Evaporator system with jet compressor steam TVR evaporation and concentration equipment It is an evaporation concentration crystallization equipment which uses TVR heat pump to recompress part of secondary steam as heat source of heating chamber. The supply conditions for stable supply of saturated steam above 0.7MPa are required. The performance of TVR is directly related to the effect of steam saving, so it is necessary to use products with guaranteed operation performance. If the quality and performance of TVR is poor, the steam saving effect is not obvious, and it is easy to damage because of the noise and vibration.
How Thermal Vapor Recompression Evaporators Work To reduce energy consumption, water vapor from an evaporator is entrained and compressed with high pressure steam in a thermocompressor so it can be condensed in the evaporator heat exchanger. The resultant pressure is intermediate to that of the motive steam and the water vapor. A thermocompressor is similar to a steam-jet air ejector used to maintain vacuum in an evaporator. Only a portion of the vapor from an evaporator can be compressed in a thermocompressor with the remainder condensed in the next-effect heat exchanger or a condenser. A thermocompressor is normally used on a single-effect evaporator or on the first effect of a double- or triple-effect evaporator to reduce energy consumption. Like mechanical recompression, thermal recompression is more applicable to low boiling-point rise liquids and low to moderate differential temperatures in the heat exchanger to minimize the compression ratio. The double-effect evaporator with thermal recompression requires 33% less steam than the conventional double effect. In essence, the steam usage for the double effect with thermal recompression is comparable to that of a triple-effect evaporator.
Features of thermal vapor recompression evaporation crystallizer: 1. In the process of thermal vapor recompression, the steam in the boiling chamber is recompressed to a higher pressure in the heating chamber according to the heat pump principle. 2. The saturated steam temperature corresponding to this heating steam pressure is high
