By adopting such scheme, consequently: the height that can be carried out perception liquid level by mechanical ball float.When liquid level is too low, mechanical ball float drives valve open charging; When liquid level reach a certain height, mechanical ball float drives valve closing, stops charging.The utility model controls the liquid level in separator by simple vibrational power flow, effectively can prevent the generation of flash problem.
Of the present utility modelly to be set to further: described two effect circulating pumps are forced circulation pump.
By adopting such scheme, consequently: in two effect separators, feed liquid viscosity after an effect circulating and evaporating improves greatly, and two effect circulating pumps adopt forced circulation pump can guarantee that evaporimeter normally works.
Of the present utility modelly to be set to further: two effect separators are DTB separator.
By adopting such scheme, consequently: DTB crystal separator can control liquid level in separator, according to different material character, different crystal separator size diameter can be designed again, effectively can control material and bubbling in the impact of crystal separator.
Of the present utility modelly to be set to further: a described effect heat exchanger is Falling film heat transfer device, described two effect heat exchangers are two-tube-pass heat exchanger.
By adopting such scheme, consequently: adopt round trip, mass flow reduces half on original basis, and improve flow velocity and reduce flow again, power of motor subtracts half, heat transfer efficiency is increased.
