热泵组合性多效蒸发设备制造
详细介绍:




热泵组合性多效蒸发可节省蒸汽用量,但随着效用数增加设备成本也会大幅增加。热泵或蒸汽再压缩(MVR)组合型多 效蒸发系统即可降低设备成本又可做到完全不用蒸汽,具有取长补短的作用。热泵或蒸汽再压缩的原理就 是将单效蒸发或多效蒸发过程中蒸汽被冷却水冷凝的热量利用起来用于废液的再蒸发,因此理论上没有热 量的损失,可不需要外部供热。但实际上压缩机的功力不可能100%转化成热能(被蒸发液的熵),所以存在 效能系数(COP)。效能系数取决于多个因数,MVR的效能系数大致在下表所示的范围之内。我们可根据客 户 的实际情况和要求设计合理、省能的热泵组合性多效蒸发浓缩系统。


The combined multi-effect evaporation of heat pumps can save steam consumption, but the cost of equipment will also increase significantly as the number of utilities increases. The heat pump or vapor recompression (MVR) combined multi-effect evaporation system can reduce equipment costs and eliminate the need for steam at all, which has the effect of complementing each other. The principle of heat pump or steam recompression is to use the heat of the steam condensed by cooling water in the single-effect evaporation or multi-effect evaporation process to re-evaporate the waste liquid. Therefore, there is no heat loss in theory and no external heating is required. But in fact, the compressor's power cannot be 100% converted into heat energy (entropy of the evaporated liquid), so there is a coefficient of efficiency (COP). The performance coefficient depends on a number of factors, and the performance coefficient of MVR is roughly within the range shown in the table below. We can design a reasonable and energy-saving heat pump combined multi-effect evaporation concentration system according to the actual situation and requirements of customers.
