Abstract
The invention discloses an evaporator and an evaporating system applying the same. The evaporator comprises a housing, an upper end cover, a lower end cover, an upper porous water distributing plate and a lower porous water distributing plate. Seamless tubes are fixed between the upper porous water distributing plate and the lower porous water distributing plate in a spaced manner. The evaporator defines the quantity, pipe diameter and length of the seamless tubes through a liquid waste output needed to be treated, so that the waste liquid flows downward along the tube walls appropriately, and are neither crystallized or fall to the bottom quickly, and the concentrating and evaporating effect is excellent. In addition, the upper porous water distributing plate is a graphite carbon plate which is high in strength. After the upper porous water distributing plate is heated, the anti-cracking property is high, so that the service life of the evaporator is prolonged. Therefore, the waste liquid and waste gas concentrating effect of a single-effect or multi-effect evaporating system using the evaporator is good, and the service life is long.
