The utility model relates to the technical field of condensing equipment, and particularly discloses a three-
pipe efficient
cascade heat
recovery condenser which comprises an inner shell and an outer shell from inside to outside, a cooling water cavity is formed between the inner shell and the outer shell, a
wine liquid condensing cavity is formed in the inner shell, and a plurality of outer heat exchange pipes are arranged in the inner shell in the vertical direction; the outer shell is provided with a plurality of inner heat exchange pipes in the vertical direction, the inner heat exchange pipes penetrate through the inner shell and penetrate through the middles of the outer heat exchange pipes, and the inner heat exchange pipes and the outer heat exchange pipes are coaxial; the shell is sequentially divided into a high-temperature cooling
water area, a medium-temperature cooling
water area and a low-temperature cooling
water area from top to bottom. The condenser aims to solve the problems that an existing condenser for
wine making only has a single inlet and outlet, and after heat exchange,
warm water is about 50 DEG C; due to low
water temperature grade, low
heat energy recycling value, narrow application range and low energy-saving benefit, a large amount of low-grade
warm water is accumulated in the
winery; secondly, cooling of a large amount of
warm water needs long-time high-load operation of a
cooling tower,
power consumption is large, and a large amount of
heat energy is wasted.
