As long as this low-temperature waste heat retracting device is made of outer barrel 1, inner cylinder 2, rotating cylinder 3 and cold water pipe 7, formed in cold water pipe 7
Cold water channel 7a forms waste heat aquaporin-4 between outer barrel 1 and rotating cylinder 3, warm Aquaporin-5 is formed between inner cylinder 2 and rotating cylinder 3,
Cold water channel 7a is connected by cold water apopore 72 with warm Aquaporin-5.
In use, spent hot water flows into waste heat aquaporin-4 from waste heat water inlet 41, and in waste heat aquaporin-4 from up to
Lower flowing is finally flowed out from waste heat water out 42；And cold water flows into cold water channel 7a from cold water inlet 71, and in cold water channel
It is flowed from top to bottom in 7a, then warm Aquaporin-5 is flowed into from the cold water apopore 72 of the lower parts cold water channel 7a, in warm Aquaporin-5
It flows from bottom to up.With from bottom to up flowing of the cold water in warm Aquaporin-5, spent hot water in waste heat aquaporin-4 from up to
Lower flowing occurs heat exchange, the water temperature of cold water is made to increase in hot water or cold water crosses flow process, to reach recycling spent hot water
The purpose of waste heat.The warm water for absorbing waste heat flows into warm water collector 6 from warm water apopore 51, is finally flowed from warm water water outlet 61
Go out to be utilized.
The rotating cylinder 3 being connected by rotary drive mechanism is arranged between waste heat aquaporin-4 and warm Aquaporin-5 in the present invention,
In device operational process, the rotation of rotating cylinder 3 stirs the water in waste heat aquaporin-4 and warm Aquaporin-5；Since water is bad
Conductor, under smooth flow state, the heat on the outside of waste heat aquaporin-4 is difficult inside transmit and is fully utilized, likewise, warm
Water on the inside of Aquaporin-5 causes water temperature rising extremely limited due to being unable to fully heat transfer, and the present invention passes through the rotation pair of rotating cylinder 3
Water is stirred, and to increase the mobility of water, so that heat is preferably transmitted, is substantially increased transmission efficiency, can
Effectively promote the effect of waste heat recovery.
Since spent hot water is flowed from top to bottom in waste heat aquaporin-4, in heat recovering process, in waste heat aquaporin-4
Water temperature taper off distribution from waste heat water inlet 41 to waste heat water out 42；And cold water flows from bottom to up in warm Aquaporin-5,
Water temperature in warm Aquaporin-5 is from cold water apopore 72 to warm water apopore 51 in incremental distribution.For example, being flowed from waste heat water inlet 41
The temperature of the spent hot water entered is 40 DEG C, and the temperature of the cold water flowed into from cold water inlet 71 is 10 DEG C of (i.e. cold water apopores 72
Water temperature is 10 DEG C), by this waste heat recovery plant heat recovery (etc. heat exchanges under the conditions of), at warm water apopore 51
Water temperature reaches as high as 39 DEG C, and the water temperature of waste heat water out 42 is 11 DEG C；In operational process, water temperature in waste heat aquaporin-4 from
40 DEG C to 11 DEG C distributions of successively decreasing, and DEG C incremental distribution from 10 DEG C to 39 of the water temperature in warm Aquaporin-5.
Highly preferred embodiment of the present invention has illustrated, and the various change or remodeling made by those of ordinary skill in the art are not
It can depart from the scope of the present invention.
