Using ceramic membrane to recover moisture from gas is a feasible way that not only can realize the recycling of resources

but also can alleviate environmental pollution. By taking double-row ceramic membrane module as the research object

the heat and mass transfer of water vapor transport was theoretically analyzed

the physical model was established

and numerical simulation was carried out according to the boundary parameters under actual conditions. Then

a pilot test platform was built on a coal-fired unit to carry out the experimental research on the purified flue gas after wet desulfurization. The results show that

the amount of recovered water decreased linearly from 29.45 kg/h to 18.13 kg/h by increasing the cooling water temperature from 25 ℃ to 36 ℃.With the growing of flue gas flowrate

the recovered water gradually increased

but the growth rate gradually decreased. The deviations of the recovery water amount between the calculated results and the experimental data were less than 7%.
