Evaporation apparatus and evaporation method adopting active carbon fiber plate as evaporation plate

Abstract

The invention relates to an evaporation apparatus adopting an active carbon fiber plate as an evaporation plate. The evaporation apparatus consists of an evaporation tank (20), a cold well (30), an air pump (40), a cleaning water trough (9) and a water pump (4); evaporated water is continuously supplemented from a water feeding pipe (5) so as to keep a water level in a water storage area constant;a spraying head (6) sprays the evaporated water to an evaporation assembly (10) by adopting the active carbon fiber plate as the evaporation plate; and the air pump (40) is started, so that the air pressure in an inner space of a tank body (7) is reduced, and the evaporated water is condensed and collected by virtue of the cold well (30).

[0002] Thermal evaporation is a common industrial production process, commonly used equipment for solid-liquid concentration and separation, liquid temperature, ambient pressure, and evaporation area are important indicators of process efficiency; there are common equipment such as multi-effect evaporators, falling film evaporators, etc. Insufficient evaporation area, easy scaling, and high operating costs;

[0003] The invention patent "A negative pressure evaporation equipment and process involving activated carbon fiber board" (201810261151.0) discloses the advantages of using activated carbon fiber board. It has a large evaporation surface area, and the activated carbon fiber board is resistant to acid and alkali, and can absorb water; only after actual use , it is found that the movable parts are prone to failure, and the total evaporation area is still too small, so further reform is necessary
