It is discharged into air, is used if adopting an effective measure and reclaiming this part water resource electric power supply plant, then energy-conservation aspect is received every year for power plant
Benefit is considerable.
Have a large amount of on being reduced using heat exchanger below flue-gas temperature to dew-point temperature so as to recovered flue gas both at home and abroad
The research of waste heat and condensate.As a kind of new " green technology ", membrane separating method also grades neck in dehumidification and recycle-water
Domain obtains more and more widely paying close attention to.But the membrane separating and trapping moisture studied at present focus mostly in the research of organic film.Have
There are high water vapor infiltration coefficient and preferable vapor and nitrogen separation machine film more.But all in all, the infiltration of organic film
Flux is much lower than inoranic membrane.For in-situ processing big flow gas, inoranic membrane has bigger application potential.Porous ceramics
Film belongs to inoranic membrane, and it shows the stability of height under high temperature and acid or alkali environment and microbial attack environment.It is this steady
It is qualitative to cause it to possess very strong applicability under this complex environment of power-plant flue gas.
Domestic applied there is presently no hollow ceramic membrane technology is furtherd investigate in the recovery of coal steam-electric plant smoke moisture.
Utility model content
The purpose of this utility model is to provide a kind of device based on hollow ceramic membranes recovered flue gas moisture and waste heat, and it is special
Levy and be：The device by hollow ceramic membrane module, vacuum system and heat exchange condenser system, and by valve, vacuum breaker,
