Wastewater recovery process and system based on hot flue gas and adsorbent
The invention discloses a wastewater recovery process and system based on hot flue gas and an adsorbent. The wastewater recovery process comprises the following steps that: a high-specific-surface-area hydrophilic filler is loaded into a humidifying tower, the adsorbent is loaded into a dehumidifying tower, a rotary dehumidifying wheel is arranged at the bottom in the dehumidifying tower, and salt-containing wastewater is sprayed from the top of the humidifying tower to the inside of the humidifying tower after heat exchange and temperature rise; hot flue gas is injected from the side face of the humidifying tower, the hot flue gas, the salt-containing wastewater and the high-specific-surface-area hydrophilic filler are in cross-flow contact in the humidifying tower for humidifying, isothermal steam phase change and cooling are conducted, moisture in the hot flue gas is recycled, and recycled water is obtained; and the hot flue gas is in contact with the adsorbent in the dehumidifying tower, the adsorbent absorbs water vapor in the hot flue gas, and the adsorbent is absorbed-extruded by the rotary dehumidifying wheel to obtain recycled water. Therefore, the technical problem of low recycling efficiency caused by complex recycling process and high recycling energy consumption in a traditional wastewater recycling method is solved; and the invention relates to the technical field of wastewater recycling.
