That is, when the waste liquid is transferred to the intermediate storage tank 80 along the inner surface 31 of the evaporation spring by the waste liquid distribution pipe 1, the air forcedly introduced into the evaporation tank 10 by the exhaust fan 40 is evaporated. Contacting the outer surface 32 of the cloth (3) to suck the moisture in the waste liquid soaked into the evaporation cloth (3), and forcibly discharged the moisture-containing air to the outside of the evaporation tank (10) (3) The waste liquid flowing downward along the inner surface 31 of the () is concentrated.
이와 같이 본 발명은 밀폐된 증발천의 내부면을 따라 폐액을 흐르게 하여 폐액으로 인한 오염확산을 방지하고, 폐액과 공기를 간접·접촉시켜 공기 유속에 의한 비말동반 현상을 제거하며, 작업효율성을 향상시키는 등 많은 효과가 있다.As described above, the present invention prevents the spread of waste due to the waste liquid by flowing the waste liquid along the inner surface of the sealed evaporation cloth, and eliminates the entrainment of the splash by the air flow rate by indirectly contacting the waste liquid with the air and improves the work efficiency. There are many effects.
