Description

Technical Field

[0001] The utility model belongs to the technical field of centrifuges, and more specifically relates to a waste heat recovery device for a centrifuge. Background Art

[0002] During operation, one of the core functions of a centrifuge is to separate liquids from solids by generating strong centrifugal force through high-speed rotation. However, during this process, the air undergoes primary, secondary, and tertiary compression, and due to energy conversion and friction effects, the temperature of the air rises significantly, usually reaching around 130°C or even higher.

[0003] Such high-temperature air poses a great challenge to the normal operation of the centrifuge. First, high temperature will accelerate the oxidation and aging of metal parts inside the equipment, shortening the service life of the equipment. Secondly, high temperature environment may also cause safety accidents such as fire, posing a threat to production safety and personnel safety. Furthermore, direct discharge of high-temperature air into the environment will also cause energy waste and environmental pollution.

[0004] In order to deal with this high-temperature air, the traditional approach is usually to use cooling equipment, such as cooling fans, to cool down the hot air discharged from the centrifuge. However, although this method can reduce the air temperature, it does not fully utilize this part of the heat energy, resulting in energy waste. At the same time, the cooling equipment itself also consumes energy, increasing operating costs.
